Introduction 
This publication provides an overview of the federal tax law rules that apply to municipal       
financing arrangements commonly known as “governmental bonds.” It is intended to help              
issuers meet federal tax law requirements to ensure that interest earned by bondholders is          
exempt from taxation under Internal Revenue Code (IRC) Section 103. 
This publication is an overview of the rules; it isn’t official guidance that you may rely on for    
planning purposes. It refers to IRC sections, Income Tax Regulations (Treas. Regs.), revenue          
procedures and other official guidance. Please refer to the official guidance for the rules that      
apply to governmental bonds. Unless otherwise indicated, references in this publication to          
section numbers are references to sections of the IRC.

qualified private activity bonds, see IRS Publication 4077, Tax-Exempt Bonds for 501(c)(3) 
Charitable Organizations, and IRS     Publication 4078, Tax-Exempt Private Activity Bonds.

Background 
State and local governments receive direct and indirect tax benefits under the IRC that lower       
borrowing costs on their valid debt obligations. Because interest paid to bondholders on these             
obligations is not includable in their gross income for federal income tax purposes, bondholders            
are willing to accept a lower interest rate than they would accept if the interest was taxable.    
These benefits apply to many different types of municipal debt financing arrangements including             
bonds, notes, loans, lease purchase contracts, lines of credit and commercial paper (collectively           
referred to as “bonds” in this publication).  
To receive these benefits, issuers must ensure that the requirements under the IRC are met,        
generally for as long as the bonds remain outstanding. These requirements include, but are not             
limited to, information filing and other requirements related to issuance, the proper and timely     
use of bond-financed property, and limitations on how bond proceeds (funds derived from          
the sale of bonds) may be invested. This publication describes these rules as they relate to      
governmental bonds. 
This publication also addresses practices and steps the issuer can take to protect the tax-
exempt status of the bonds. For example, because the requirements and limitations generally          
apply at the time the bonds are issued and throughout the term of the bonds, this publication        
encourages issuers and beneficiaries of tax-exempt bonds to create procedures for monitoring               
compliance throughout the life of the bonds. For more information, see      Post-Issuance 
Compliance Monitoring. 

Tax-Exempt Governmental Bonds 
Governmental bonds are bonds that do not meet the private activity bond tests. Proceeds          
of these bonds may be used to finance activities of, or facilities owned, operated or used    
by, the issuer for its purpose or another state or local government for its own purposes. This      
can include financing the construction, maintenance or repair of public infrastructure such as       
highways, schools, fire stations, libraries or other types of municipal facilities. To be tax-exempt,       
governmental bonds must comply with the requirements that define governmental bonds and              
requirements that apply to tax-exempt bonds generally.      
In this section, we discuss the tests for determining whether a bond is a governmental bond        
or a private activity bond. These tests apply at issuance and after the bonds are issued. This      
discussion includes remedial action provisions that apply when a deliberate action causes        
governmental bonds to become private activity bonds. If a deliberate action that results in a      
violation of any of the federal tax requirements cannot be corrected under the remedial action            
provisions, issuers may be able to enter into a closing agreement under the TEB Voluntary        
Closing Agreement Program (TEB VCAP) described in          Notice 2008-31, 2008-11 I.R.B. 592 (see  
What To Do When You Discover a Violation — TEB Voluntary Closing Ageement Program                     ).

Testing for Governmental Bonds: The Private Activity Bond Tests 
IRC Section 141 sets forth tests to determine if a bond is a private activity bond. These tests      
identify arrangements that actually, or are reasonably expected to, transfer benefits of tax-
exempt financing to a nongovernmental person. A “nongovernmental person” is a person             
other than a governmental person. A governmental person means a state or local government              
as defined in Treas. Reg. Section 1.103-1 or any instrumentality of such entity. Governmental        
persons do not include the United States or any agency or instrumentality of the United States.         
A state or local bond will be a private activity bond if, as of the issue date of the bonds or at any    
time while the bonds are outstanding, the bond issue exceeds the limits set forth in either:       
   „ the private business tests of Section 141(b), which consist of the private use test and the
     private security and payment test, and certain special private business rules (see Special
     Private Business Test Rules and Special Rules for Certain Utility Financings, below), o
   „ the private loan financing test of Section 141(c). 
The bond issue exceeds the private activity bond tests limits as of the issue date if the issuer      
or a conduit borrower of the bond proceeds reasonably expects that the issue will exceed the           
limits while the bonds are outstanding. A bond issue also exceeds the private activity bond tests        
limits after the issue date if a deliberate action is taken that causes those limits to be exceeded.    
If a bond is a private activity bond, interest on the bond may still be excludable from federal     
income tax if the bond issue meets the additional requirements that apply to qualified private       
activity bonds. For a discussion of these additional requirements, see Publication 4078, Tax-
Exempt Private Activity Bonds. 

Private Business Tests 
Under IRC Section 141(b), a bond issue exceeds the limits of the private business tests, and        
therefore does not qualify as a governmental bond issue, if the issue exceeds the limit of the       
private business use test   and also exceeds the limit of the private security or payment test.     
Private Business Use Test. A state or local bond issue exceeds the limit of the private business  
use test if more than 10% of the proceeds of an issue are to be used for any private business  
use. Use of bond proceeds or bond-financed property by a nongovernmental person (individual  
or entity) in furtherance of a trade or business activity is considered private business use for tax-
exempt bond purposes. For this purpose, any trade or business activity of a natural person is  
treated as a trade or business, and any activity carried on by a person (including a governmental  
entity or corporation) other than a natural person is treated as a trade or business.  
Indirect uses of proceeds must also be considered in determining whether more than 10% of the            
proceeds of an issue will be used in a private business use. For example, property is treated as        
being used for a private business use if it is leased to a nongovernmental person and then sub­
leased to a governmental person if the nongovernmental person’s use is in a trade or business.          
Many types of arrangements can result in private business use under IRC Section 141 at          
issuance or later, including management and service contracts and research agreements.           
Management and Service Contracts.      Contracts for a private entity to manage a bond-financed        
facility may cause the private business use test to be met. For example, a management        
contract between a governmental entity and a nongovernmental person under which the             
nongovernmental person receives compensation for services provided with respect to bond-
financed property may result in the bonds meeting the private business use test.

The IRS has provided safe harbors protecting against private business use for management             
and service contracts between a private entity and a governmental entity when the service           
is provided in connection with bond-financed property. For more information, see Revenue 
Procedure 2017-13. Contracts that fail the safe harbor do not automatically meet the private          
business use test; all facts and circumstances are considered to determine whether the contract            
meets the test. 
Research Agreements.  Research agreements may also cause the private business use test              
to be met. For example, when private entities or the federal government sponsor research at           
a facility financed with tax-exempt bonds, the research agreements may result in the bonds           
meeting the private business use test. However, the IRS has provided safe harbors for research            
agreements. For more information, see Revenue Procedure 2007-47, 2007-29 I.R.B. 108. As 
with management contracts, failure to meet the safe harbors does not automatically cause the             
private business use test to be met. 
NOTE: If an issuer determines that its bonds meet the private business use test, the bonds have            
not met the private business tests unless the bonds also meet the private payment or security           
test.  
Private Security or Payment Test.        A state or local bond exceeds the limit of the private   
security or payment test if more than 10% of the proceeds of the bond issue is (under the terms            
of the issue or any underlying arrangement) directly or indirectly (1) secured by any interest in      
property used or to be used for a private business use or payments in respect of the property, or           
(2) to be derived from payments (whether or not to the issuer) in respect of property, or borrowed          
money, used or to be used for a private business use. For example, lease payments made by              
private businesses to a city for the lease of property in a blighted area that was rehabilitated with       
proceeds of the city’s bonds would be treated as private payments. 
NOTE: If an issuer determines that its bonds meet the private security or payment test, the         
bonds have not met the private business tests unless the bonds also meet the private business             
use test. 
Special Private Business Test Rules.        Additional limits on private business activity apply   
when private business use is unrelated to the governmental use, when private business use is            
disproportionate to the governmental use, and when the “nonqualified amount” exceeds $15              
million. 
Unrelated and Disproportionate Use.       IRC Section 141(b)(3) provides an additional limit for  
unrelated and disproportionate business use, which is lower than the limits in Sections 141(b)(1)         
and 141(b)(2). In particular, it limits unrelated or disproportionate private use of assets financed     
with governmental bonds to 5% of the proceeds of the bonds. The rule also reduces the private             
security or payment test limit to 5%. For this purpose, only payments, property and borrowed            
money with respect to the unrelated or disproportionate use are taken into account.         
Unrelated use is private use that isn’t related to the governmental use of the issue. Whether        
a private business use is related to a government use financed with the proceeds of an issue           
is determined on a case-by-case basis, emphasizing the operational relationship between the             
government use and the private business use. In general, a facility that is used for a related      
private business use must be located within, or adjacent to, the governmentally-used facility. 
   Example: A county issues bonds with proceeds of $20 million and uses $18.1 million of           
   the proceeds for construction of a new school building and $1.9 million of the proceeds for          

4 



- 7 -
   construction of a privately operated cafeteria in its administrative office building, which is      
   located at a remote site. The bonds are secured, in part, by the cafeteria. The $1.9 million of            
   proceeds is unrelated to the governmental use (that is, school construction) financed with           
   the bonds and exceeds 5% of $20 million. Thus, the issue exceeds the limit under the private                
   business tests. 
A private business use is disproportionate to a related government use only to the extent that           
the amount of proceeds used for that private business exceeds the amount of proceeds of               
the issue used for the related government use. For example, a private use of $100 million of           
proceeds that is related to a government use of $70 million of proceeds results in $30 million of              
disproportionate use. 
When unrelated use and disproportionate use occur in the same bond issue, the two uses are                   
aggregated to test against the 5% limit. Additional examples of the unrelated or disproportionate               
private use limits may be found in Treas. Reg. Section 1.141-9(e).      
Remedial Actions for Unrelated or Disproportionate Use.         A deliberate action that occurs after    
the issue date does not result in unrelated or disproportionate use if the issue meets the         
remedial action provisions in Treas. Regs. Section 1.141-12(a), discussed in       Remedial Actions for 
Nonqualified Use. 
The $15 Million Limit on the Nonqualified Amount.        An additional limit may apply even though      
the “nonqualified amount” of proceeds does not exceed 10% of the proceeds of the bonds (or                   
a lesser amount of unrelated or disproportionate use of proceeds), and therefore the private           
activity limits discussed above have not been exceeded. The nonqualified amount is the lesser                
of the amount of proceeds used in private business use or the amount of proceeds with respect                   
to which there are private payments or security. Section 141(b)(5) provides that an issue of         
bonds will be private activity bonds if the nonqualified amount exceeds $15 million, unless the           
issuer applies state volume cap under Section 146 to the excess of the nonqualified amount             
over $15 million. For additional information on the state volume cap limit under Section 146, see              
Publication 4078, Tax-Exempt Private Activity Bonds. 
Special Rules for Certain Utility Financings.        There are two additional limits that issuers of    
bonds for utility projects should consider. The first limit, under Section 141(b)(4), applies if 5% or          
more of the proceeds of the issue are to be used to finance any “output facility,” as          defined   in the 
regulations (other than a facility for the furnishing of water). Section 141(b)(4) limits the nonqualified 
amount of proceeds of a governmental bond issued to finance the output facilities to $15            
million. This rule applies in addition to the tests under Section 141(b)(1) and (2). In applying this        
limit, issuers must include the nonqualified amounts on any prior outstanding tax-exempt bond                 
issues for which 5% or more of the proceeds of the prior issue are or will be used for either the             
same output facility or another output facility that is part of the same project. If the nonqualified          
amount exceeds $15 million, the bonds are private activity bonds. 
Under the second limit, bonds will be private activity bonds if the amount of the proceeds of           
the issue that are to be used (directly or indirectly) for the acquisition by a governmental unit       
of nongovernmental output property exceeds the lesser of 5% of the proceeds or $5 million.              
“Nongovernmental output property” means any property (or interest therein) which before the              
acquisition was used (or held for use) by a person other than a governmental unit in connection                
with an output facility (other than a facility for the furnishing of water). The rule has several    
exceptions, which are beyond the scope of this publication.

Private Loan Financing Test 
A state or local bond exceeds the limit of the private loan financing test if the amount of    
proceeds of the issue which is to be used (directly or indirectly) to make or finance loans to     
persons other than governmental entities exceeds the lesser of 5% of the proceeds or $5 million.          
A bond that exceeds the private loan financing test limit is a private activity bond, even if it does    
not also meet the private business tests.  

Exceeding the Private Activity Bond Tests Limits after Issuance 
Even if the bonds comply with the limits of the private activity bond tests at issuance, a     
governmental bond issue can lose its tax-exempt status (from the time of issuance) if the issuer        
or a conduit borrower of the bond proceeds takes a “deliberate action” after the issue date        
that causes the issue to exceed those limits. A deliberate action is any action taken by the      
issuer or conduit borrower that is within its control; intent to exceed the limits is not necessary    
for an action to be deliberate. A deliberate action occurs on the date the issuer or conduit      
borrower enters into a binding contract (that is not subject to any material contingencies) with     
a nongovernmental person for use of the bond-financed property in a manner that causes the           
limits of the private activity tests to be exceeded. 
Remedial Actions for Nonqualified Use.         The regulations provide that an issuer and, in   
conduit financings, a conduit borrower that engages in a deliberate action causing the limits       
of the private activity bond tests to be exceeded may, in certain cases, cure that deliberate      
action. Treas. Reg. Section 1.141-12 provides that an issuer may take remedial actions to cure       
a deliberate action that would otherwise cause the bonds to lose their tax-exempt status. The        
remedial actions include redemption or defeasance of nonqualified bonds, alternative use of         
disposition proceeds and alternative use of bond-financed property.      
   Example: A city enters into an agreement through which it sells a building financed with        
   governmental bond proceeds to a corporation and leases the same building back from that           
   corporation, with the result that the corporation owns the building for federal income tax      
   purposes. This change in ownership of the property results in private business use and is a       
   deliberate action. However, the city may remediate the deliberate action by redeeming the        
   nonqualified bonds within 90 days of the action.     

Other Governmental Bond Requirements 
Other rules an issuer must meet for a governmental bond to be tax-exempt include: 
  „  rules a governmental bond must meet for interest to be excluded from federal income tax, 
     including rules that relate to issuance of the bonds (including elections that need to be made 
     when the bonds are issued) and rules that apply at issuance and throughout the life of the 
     bonds; 
  „  rules that apply when modifications are made to bond terms; and 
  „  recordkeeping requirements.

Requirements Related to Issuance 
The following is an overview of several general rules related to the issuance of governmental              
bonds. 
Issuers Must File an Information Return.           Issuers of governmental bonds must comply with            
certain information filing requirements under IRC Section 149(e). The size of the issuance            
dictates which information return an issuer must file. The chart below describes what form             
is required and when it must be filed. The        IRS Forms     listed below are available on the TEB  
website. 

Information Reporting Under Section 149(e) 

Information Return                 Due Date                                     Where to File 
Form 8038-G, Information           Generally, both returns are due on or        File Form 8038-G and Form    
Return for Tax-Exempt              before the 15th day of the 2nd calendar      8038-GC information returns   
Governmental Bonds    ,            month after the close of the calendar        at: 
for a governmental bond            quarter in which the bonds were              Department of the Treasury   
issue with an issue price of       issued.                                      Internal Revenue Service  
$100,000 or greater.               Example: The due date of the return          Center  
                                   for bonds issued on February 1 is May        Ogden, UT 84201 
                                   15. 
Form 8038-GC, Information          Alternatively, Form 8038-GC may       
Return for Small Tax-Exempt        be filed annually on a consolidated    
Governmental Bond Issues       ,   basis for all bond issues of less than   
Leases, and Installment            $100,000 that are not reported on     
Sales, for a governmental          a separate Form 8038-GC and that       
bond issue with an issue           are not construction issues electing    
price of less than $100,000.       to pay a penalty in lieu of rebate.  
May be filed for a single          Consolidated returns are due on or     
issue or on a consolidated         before February 15 following the     
basis for all “small” issues in    calendar year in which the bonds were      
a calendar year.                   issued. 
                                   Example: An issuer issues three      
                                   governmental bond issues with issue      
                                   prices and dates as follows: $50,000     
                                   Issue A - March 1, 2018; $75,000 Issue     
                                   B - June 15, 2018; and $30,000 Issue      
                                   C - October 5, 2018. This issuer can    
                                   file one consolidated Form 8038-GC       
                                   by February 15, 2019 for all three bond    
                                   issues. 

An issuer may request an extension of time to file Forms 8038-G or 8038-GC if the failure to file              
the return on time wasn’t due to willful neglect. To request an extension, the issuer must follow             
Revenue Procedure 2002-48, 2002-37 I.R.B. 531             . These procedures generally require that the       
issuer: (1) attach a letter to the Form 8038-G or Form 8038-GC briefly explaining when the return               
was required to be filed, why the return was not timely submitted, and whether the bond issue is                
under examination; (2) enter on top of the letter “Request for Relief under section 3 of Rev. Proc.             
2002-48” and (3) file the letter and return at the Internal Revenue Service Center, Ogden, UT              
84201. 
Bonds Must Be in Registered Form.            IRC Section 149(a) generally provides that any tax-exempt          
bond, including governmental bonds, must be issued “in registered form” unless the bond is not                  
of a type offered to the public or has, at the date of issue, a maturity of not more than one year.

The regulations describe what it means to be in “registered form.” Treas. Reg. Section 5f.103­
1(c)(1) provides that an obligation issued after January 20, 1987, pursuant to a binding contract       
entered into after January 20, 1987, is in registered form if:  
  „  the obligation is registered as to both principal and any stated interest with the issuer (or 
     its agent) and that the transfer of the obligation to a new holder may be effected only by 
     surrender of the old instrument and the issuer must either reissue the old instrument or issue a 
     new instrument to the new holder, or 
  „  the right to the principal of, and stated interest on, the obligation may be transferred only
     through a book-entry system maintained by the issuer (or its agent); or
  „  the obligation is registered as to both principal and any stated interest with the issuer (or its 
     agent) and may be transferred through both the above methods. 
Issuers Must Make Certain Elections at Issuance.          When an issuer considers actions it must       
take when it issues bonds, it should consider whether it wants to make any elections. Various       
provisions of the IRC and regulations require that the issuer make certain elections in writing and       
retain elections as part of the bond documents. Many elections have to be made on or before         
the issue date of the bonds. Some elections may be made by either the issuer or a conduit        
borrower. Others must be made by the actual issuer of the bonds. The IRS frequently observes             
that issuers make the written elections in the arbitrage certificate prepared pursuant to Treas.    
Reg. Section 1.148-2. Once made, elections cannot be revoked without IRS permission.       
Examples of elections include: 
  „  waiving the right to treat a purpose investment as a program investment 
  „  waiving the right to invest in higher yielding investments during any temporary period 
  „  the issuer of a pooled financing issue electing to apply rebate spending exceptions separately 
     to each conduit loan 
  „  applying actual facts rather than reasonable expectations for certain provisions under the two-
     year spending exception from rebate 
  „  excluding the earnings on a reasonably required reserve fund from available construction
     proceeds under the two-year spending exception from rebat
  „  treating a portion of an issue as a separate construction issue under the two-year spending 
     exception from rebate 
  „  electing to pay 1.5% penalty in lieu of arbitrage rebate 
  „  electing to treat portions of a bond issue as separate issues 

Requirements that Apply at Issuance and Throughout the Life of the Bonds 
Proceeds Must Be Timely Allocated to Expenditures.          Issuers and conduit borrowers must      
follow the rules for allocating bond proceeds. The issuer or other entity controlling expenditure       
of the proceeds of a governmental bond issue must allocate those proceeds among the various              
expenditures or other purposes of the issue in a manner demonstrating that the private activity         
bond tests are not met. These allocations must generally be consistent with the allocations      
made for determining compliance with the arbitrage yield restriction and rebate requirements,       
as well as other federal tax filings. See Proceeds are Subject to Investment Restrictions: the      
Arbitrage Yield Restriction and Arbitrage Rebate Requirements for an overview of those rules.

- 11 -
An issuer must allocate proceeds to expenditures not later than 18 months after the later of        
the date each expenditure is paid or the date the project, if any, that is financed by the issue is     
placed in service. This allocation must be made in any event by the date 60 days after the fifth        
anniversary of the issue date or the date 60 days after the retirement of the issue, if earlier.   
Proceeds are Subject to Investment Restrictions: the        Arbitrage Yield Restriction and         
Arbitrage Rebate Requirements.        Issuers of tax-exempt bonds, including governmental bonds,          
are generally subject to investment or arbitrage limitations under IRC Section 148. Failure to      
comply with those arbitrage limitations will result in the bonds being arbitrage bonds and interest        
on the bonds being taxable.    
In general, arbitrage is earned when the gross proceeds of an issue are used to acquire       
investments that earn a yield that is materially higher than the yield on the bonds of the issue.      
Earning arbitrage is permitted in certain circumstances. In some circumstances arbitrage may           
be earned but must be paid, or rebated to the U.S. Department of the Treasury. In some cases,            
an issuer may be able to reduce the yield on an investment for arbitrage purposes and thereby           
avoid an arbitrage violation by making a yield reduction payment to the U.S. Treasury. See         
Where and When to File Arbitrage Rebate Yield Reduction Payments           , for information on how 
to make yield reduction payments.     
An issuer must comply with two general sets of arbitrage rules: (1) the yield restriction   
requirements of Section 148(a) and (2) the rebate requirements of Section 148(f). An issuer may         
meet one of these rules but still have arbitrage bonds because it failed to meet the other. Even        
though interconnected, both sets of rules have their own distinct requirements. The following         
is an overview of the basic requirements of these two general rules. Additional requirements or         
exceptions, beyond the scope of this publication, may apply in certain instances. 
An issuer’s reasonable expectations on the issue date regarding the amount and use of gross            
proceeds of the issue are used to determine whether an issue consists of arbitrage bonds. In          
addition, if an issuer or any person acting for the issuer takes a deliberate, intentional action to    
earn arbitrage after the issue date, that action will cause the bonds of an issue to be arbitrage      
bonds if that action, had it been reasonably expected on the issue date, would have caused the            
bonds to be arbitrage bonds. Intent to violate the requirements of Section 148 is not necessary          
for an action to be intentional.  
Yield Restriction Requirements.    The yield restriction rules of IRC Section 148(a) generally provide     
that the direct or indirect investment of the gross proceeds of bonds in investments earning    a 
yield materially higher than the yield of the bond issue causes the bonds to be arbitrage bonds.  The  
chart below describes when the yield on particular investments will be “materially higher” (the        
chart shows the permitted yield spread between the yield on the bond issue and the yield on the            
particular investment; any spread beyond that stated is materially higher):

“Materially Higher” Limits 

Type of Investments                                   Materially Higher 
General rule (when other rules below don’t apply)     1/8 of one percentage point 

Investments in a refunding escrow                     1/1000 of one percentage point  
Investments allocable to replacement proceeds         1/1000 of one percentage point 

Program investments                                   1.5 percentage points 
Investments in tax-exempt bonds that are not          No yield limitation 
subject to the alternative minimum income tax 

Certain exceptions are available under the yield restriction rules. The investment of proceeds     
in materially higher yielding investments does not cause the bonds of an issue to be arbitrage      
bonds: (1) during a temporary period (for example, three-year temporary period for capital   
projects and 13 months for restricted working capital expenditures); (2) as part of a reasonably     
required reserve or replacement fund; and (3) as part of a minor portion (an amount not    
exceeding the lesser of 5% of the sale proceeds of the issue or $100,000). Whether the arbitrage        
yield restrictions rules apply, issuers should consider whether the rebate requirements apply.     
Rebate Requirements.      The rebate requirements of IRC Section 148(f) generally provide that,   
unless certain earnings on “nonpurpose investments” allocable to the gross proceeds of an         
issue are rebated to the U.S. Treasury, the bonds in the issue will be arbitrage bonds. Generally,     
nonpurpose investments are investment securities such as Treasury bonds, bank deposits or          
guaranteed investment contracts, and so on, and do not include “purpose investments.” A         
purpose investment is an investment that the issuer acquires to carry out the governmental       
purpose of an issue. An example of a purpose investment is the loan obligation created when an          
issuer loans bond proceeds to another governmental unit, such as in a pooled or “bond bank”          
financing. 
The arbitrage that must be rebated is based on the excess (if any) of the amount actually earned       
on nonpurpose investments over the amount that would have been earned if those investments            
had a yield equal to the yield on the issue, plus any income attributable to the excess. Under     
Treas. Reg. Section 1.148-3(b), the future values (as of the computation date) of all earnings   
received and payments actually or constructively made on nonpurpose investments are included            
in determining the amount of rebate due.   
See Where and When to File Arbitrage Rebate Yield Reduction Payments            for information on 
how to make rebate payments. 
There are, however, two types of exceptions to the general rebate requirements that apply to       
governmental bonds: the small issuer exception and the spending exceptions.        
Small Issuer Exception.  This exception provides that governmental bonds issued by small     
governmental issuers with general taxing powers are treated as meeting the arbitrage rebate        
requirement. A governmental entity has general taxing powers if it has the power to impose       
taxes of general applicability which, when collected, may be used for its general purposes.      

10 



- 13 -
An issue (other than a refunding issue, for which other rules apply) qualifies for the small issuer            
exception only if the issuer reasonably expects as of the issue date to issue, or in fact issues,            
$5 million or less in tax-exempt governmental bonds during the calendar year. The aggregation                  
rules of Section 148(f)(4)(D) should be considered when determining whether this exception            
applies. The $5 million limit is increased by the aggregate face amount of bonds attributable to               
financing the construction of public school facilities, up to an additional $10 million. For example,            
the small issuer exception could apply if the qualifying issuer issued $5 million in tax-exempt            
governmental bonds for street improvements and $5 million in tax-exempt bonds to finance                  
construction of public school facilities in the same calendar year. 
An issue meeting the small issuer requirements is exempt from rebate for all gross proceeds.                
However, the small issuer exception is an exception from rebate and not from the arbitrage rules                
altogether. The yield restriction rules still apply. Therefore, an issuer qualifying for this exception         
needs to establish a temporary period for project fund investments and needs to establish that                 
any reserve fund is reasonably required. 
Spending Exceptions.     There are three spending exceptions to the rebate requirements. Whether                
these exceptions apply depends on the timing of expenditures of required amounts of proceeds,                    
as follows: 

Spending Exceptions 

Spending           Spending Exception 
Period 
6 months           Treas. Reg. Section 1.148-7(c) provides an exception to rebate if the gross proceeds        
                   of the bond issue are allocated to expenditures for governmental or qualified   
                   purposes that are incurred within 6 months after the issue date. 

18 months          Treas. Reg. Section 1.148-7(d) provides an exception to rebate if the gross proceeds        
                   of the bond issue are allocated to expenditures for governmental or qualified   
                   purposes which are incurred within: (1) at least 15% within 6 months after the issue       
                   date; (2) at least 60% within 12 months after the issue date; and (3) 100% within 18      
                   months after the issue date. 
2 years            Treas. Reg. Section 1.148-7(e) provides an exception to rebate for construction issues       
                   financing property to be owned by a governmental entity or 501(c)(3) organization       
                   when certain available construction proceeds are allocated to expenditures: (1) at      
                   least 10% within 6 months after the issue date; (2) at least 45% within 12 months       
                   after the issue date; (3) at least 75% within 18 months after the issue date; and (4)    
                   100% within 24 months after the issue date. 
Note: Issuers may still owe rebate on amounts earned on nonpurpose investments allocable to proceeds            
not covered by one of the spending exceptions, which may include earnings in a reasonably required          
reserve or replacement fund.

Where and When To File Arbitrage Rebate and Yield Reduction Payments           . Issuers of tax-exempt 
bonds file  Form 8038-T, Arbitrage Rebate, Yield Reduction and Penalty in Lieu of Arbitrage          
Rebate, to make: 
  „   yield reduction payments 
  „   arbitrage rebate payments 
  „   payments of a penalty in lieu of rebate 
  „   payment in connection with the termination of the election to pay a penalty in lieu of arbitrage 
      rebate 
  „   payment of the penalty for failure to pay arbitrage rebate on time 
A yield reduction payment or arbitrage rebate installment payment is required to be paid no        
later than 60 days after the “computation date” to which the payment relates. An issuer of a       
fixed yield issue may treat any date as a computation date. An issuer of a variable yield issue      
may treat the last day of any bond year ending on or before the latest date for making the first      
rebate payment (generally not later than five years after the issue date) as a computation date.      
Thereafter, the issuer must consistently treat either the end of each bond year of the end of each        
fifth bond year as a computation date. Generally, a “bond year” is a one-year period that ends        
on the date that the issuer selects. If the issuer does not make a timely selection, the bond years       
for the issue end on each anniversary of the issue date and on the final maturity date.      
Recovering an Overpayment of Rebate.      If an issuer pays more than the required rebate, it may     
ask to recover the overpayment. In general, an issuer may request an overpayment of arbitrage          
rebate when it can establish that an overpayment occurred. An overpayment is the excess of          
the amount paid to the U.S. Treasury for an issue under IRC Section 148 over the sum of the         
rebate amount for the issue as of the most recent computation date and all amounts that are         
otherwise required to be paid under Section 148 as of the date the recovery is requested. The         
request can be made with the IRS by completing and filing      Form 8038-R, Request for Recovery          
of Overpayments Under Arbitrage Rebate Provisions         . An issuer must file a Form 8038-R no     
later than the date that is two years after the final computation date for the issue. For more    
information, see Treas. Reg. Section 1.148-3(i). 
Special Remedial Action for Failure to Timely Pay Arbitrage Rebate     . An issuer that fails to timely  
pay arbitrage rebate will be excused from having its bonds be arbitrage bonds if the failure isn’t     
due to willful neglect and the issuer submits a Form 8038-T with a payment of the rebate amount           
owed, plus penalty and interest. The penalty may be waived under certain circumstances. For           
more information, see Treas. Reg. Section 1.148-3(i)(3) and    Revenue Procedure 2005-40, 2005­
28 I.R.B. 83. 
Bonds May Not Be Federally Guaranteed. IRC Section 149(b) provides that any tax-exempt  
bond, including a governmental bond, will not be treated as tax-exempt if the payment of  
principal or interest is directly or indirectly guaranteed by the federal government or any agency  
or instrumentality of the federal government. Exceptions to this general rule include guarantees  
by certain quasi-governmental entities administering federal insurance programs, and federal  
guarantees for qualified residential rental projects, home mortgages and student loans. Additional  
exceptions apply for the investment of bond proceeds that are invested in U.S. Treasury securities  
or held in a bona fide debt service fund, a reasonably required reserve or replacement fund or a  
refunding escrow, and investments during a permitted initial temporary period.  

12 



- 15 -
A Bond May Not Be a Hedge Bond         . IRC Section 149(g) states that hedge bonds will not be     
tax-exempt unless certain requirements, described below, are satisfied. A “hedge bond” is any          
bond that is part of a bond issue that fails either of the following requirements:  
   „  The issuer must reasonably expect that 85% of the spendable proceeds of the issue will be 
      used to carry out the qualified purpose within the three-year period beginning on the date the 
      bonds are issued (“spendable proceeds” means proceeds from the sale of the issue, less the 
      portion invested in a reasonably required reserve or replacement fund or as part of a permitted 
      “minor portion”). 
   „  Not more than 50% of the proceeds of the issue are invested in nonpurpose investments
      having a substantially guaranteed yield for four or more years.
Section 149(g)(3)(B) provides an exception to the general definition of a hedge bond if at least     
95% of the net proceeds of the issue are invested in tax-exempt bonds that are not subject       
to the alternative minimum tax. For this purpose, amounts held either: (1) in a bona fide debt      
service fund, or (2) for 30 days or less pending either reinvestment of the proceeds or bond    
redemption, are treated as invested in tax-exempt bonds not subject to the alternative minimum          
tax. Additionally, a refunding bond issue does not generally consist of hedge bonds if the prior      
issue met the requirements for tax-exempt status and issuance of the refunding bonds furthers a          
significant governmental purpose (for example, realize debt service savings, but not to otherwise        
hedge against future increases in interest rates).  
Even if an issue otherwise meets the definition of a hedge bond, it will generally still be tax-
exempt if two requirements are satisfied. First, at least 95% of the reasonably expected legal       
and underwriting costs associated with issuing the bonds must be paid within 180 days after          
the issue date and the payment of such costs must not be contingent upon the disbursement of            
the bond proceeds. Second, on the date of issuance the issuer must reasonably expect that the           
spendable proceeds of the issue will be allocated to expenditures for governmental or qualified        
purposes within the following schedule:    
   „  10% within 1 year after the date of issuance; 
   „  30% within 2 years after the date of issuance; 
   „  60% within 3 years after the date of issuance; and 
   „  85% within 5 years after the date of issuance. 
Limitations on Refunding Governmental Bonds.          Governmental bonds may be currently      
refunded. The Tax Cuts and Jobs Act (2017) repealed the exclusion from gross income for        
interest on bonds issued to advance refund another bond. The repeal applies to advance        
refunding bonds issued after December 31, 2017. A bond is classified as an advance refunding if          
it is issued more than 90 days before the redemption of the refunded bonds. Under Treas. Reg.          
Section 1.150-1(d)(1), a refunding bond issue is an issue the proceeds of which are used to pay       
principal, interest, or redemption price on another issue (a prior issue), as well as the issuance    
cost, accrued interest, capitalized interest on the refunding issue, a reserve or replacement fund,      
or any similar cost properly allocable to that refunding issue.  
Refunding issues generally derive their tax-exempt status from the prior issue they refund; if the      
prior issue was not tax-exempt, the refunding bonds generally cannot be tax exempt.

Bonds May Not Be Used for Abusive Tax Transactions 
The IRS, is engaged in extensive efforts to curb abusive tax shelter schemes and transactions.   

What Happens When the Terms of a Bond are Modified? 
If the terms of a governmental bond are sufficiently modified, the bond will be treated as    
reissued. When bonds are reissued, either actually or in a deemed reissuance, the new bonds           
must be retested as of the date of the reissuance to determine if all the federal tax requirements      
are met for the “new” issue. These include the requirements that apply when bonds are issued,          
such as timely filing of the Form 8038-G or 8038-GC. See       Requirements Related to Issuance       
Issuers Must File an Information Return. 
A deemed reissuance may arise if sufficient changes are made to the bond terms, such as when            
a bondholder and issuer agree, directly or indirectly, to a significant modification of the terms of   
any bonds. See    Reissuance of Tax-Exempt Obligations: Some Basic Concepts             for examples 
of significant modifications. If deemed reissued, the modified bonds are deemed exchanged           
for the original bonds. In general, the date the issuer and bondholder enter into the agreement       
to modify the terms of the bonds is treated as the date of issuance of the new bonds, even if       
the modification is not immediately effective. At reissuance, the modified bond must meet any         
tax law requirements that apply upon its early retirement in connection with the reissuance,       
including the acceleration of any arbitrage rebate or yield reduction payment that is due. See      
Where and When To File Arbitrage Rebate and Yield Reduction Payments. 

Issuers Must Retain Records to Show that Requirements are Satisfied  
IRC Section 6001 and Treas. Reg. Section 1.6001-1(a) generally provide that any person subject         
to income tax, or any person required to file a return of information with respect to income (for     
example, the issuer filing information returns relating to its bond issues), must keep any books      
and records as are sufficient to establish the amount of gross income, deductions, credits     
or other matters required to be shown by that person in any return. See      Frequently Asked 
Questions for more information. 

Post-Issuance Compliance Monitoring 
In this section, we discuss the importance of issuers monitoring compliance with the IRC      
requirements and suggest steps an issuer may take to monitor its bond issues. 

Protecting Against Post-Issuance Violations 
Issuers may be concerned with how they can further protect the tax-exempt status of their      
bonds. Reliance solely on bond documents and tax certificates provided when the bonds are            
issued will not likely provide the assurance an issuer desires. To gain greater confidence that     
bonds are in compliance with federal tax laws, an issuer may adopt post-issuance monitoring          
procedures. Issuers that establish and follow comprehensive written monitoring procedures          
to promote post-issuance compliance generally are less likely to violate the federal tax     
requirements related to its bonds, and are more likely to find any violations earlier, than those    
without procedures. Early discovery of a violation is a factor IRS considers in determining the      
appropriate resolution under its TEB VCAP.

Steps to Better Monitoring 
In formulating its procedures, an issuer may consider: 
„   designating one or more officials to assist in post-issuance compliance; 
„   designating one or more officials to assist with and respond to examinations of the bond issue; 
„   providing training or other technical support to designated officials; 
„   designating time intervals within which compliance monitoring activities will be completed; and 
„   timely completing remedial actions (including requests under TEB VCAP) to correct or
    otherwise resolve identified noncompliance
The chart below identifies particular areas for compliance monitoring procedures.

What To Do When You Discover a Violation — TEB Voluntary Closing Ageement 
Program 
The IRS is committed to resolving federal tax violations with the issuer. The TEB Voluntary Closing  
Agreement Program (TEB VCAP) provides remedies for issuers of tax-exempt bonds, tax credit  
bonds, and direct pay bonds that voluntarily come forward to resolve a violation that cannot be  
corrected under self-correction programs described in the regulations or other published guidance.  
Notice 2008-31, 2008-11 I.R.B 592, provides information and general guidance about TEB VCAP.  
Internal Revenue Manual (IRM) section 7.2.3 provides general procedures under which TEB will enter  
into closing agreements. Closing agreement terms and amounts may vary according to the degree of  
the violation as well as the facts and circumstances surrounding it.  
Issuers must use IRS Form 14429, Tax Exempt Bonds Voluntary Closing Agreement Program                 
Request, to submit a request and provide the required information. See IRM section 7.2.3.2.1 
about completing the March 2013 version of the form.    
For more information about this program, including request submission requirements, case          
processing procedures, and resolutions standards, see   IRM section 7.2.3   . See Voluntary 
Compliance (for more information on TEB VCAP administrative procedures and resolution      
standards).
