Publication Format 
The format of this publication is designed in an effort to consolidate the documentation and 
make it easier to review. In this publication, you will see references to detailed sections, instead 
of having all the content in the publication itself. These are noted by bold, black text and 
underlined. While this is not a live link to the document itself, you simply need to use your back 
button on your browser to return to the web page to find the actual link. There may be some 
embedded links in this document, as well, that will allow you to open another document directly. 
These will be in blue text and underlined. 
It is our hope that this will let you review the publication in more of a summary format, with 
some of the detailed contents in separate documents. This will also allow you to print or save off 
only the additional section(s) that you need for quick review. (For instance, the publication will 
refer you to the Administrative Highlights document, but the link to the Administrative 
Highlights will be a separate link on the same page where you accessed this publication 
document).  

Subscribe for Email Updates 
The department strongly recommends that all Software Developers, EROs, and Transmitters 
subscribe to our website in order to automatically receive email notifications whenever updates 
to our publications are posted. If you do not already subscribe, please click on the subscription

Getting Started   
Modernized e-File (MeF) 
Indiana accepts electronic returns through the IRS Fed/State Electronic Filing Program under the 
Modernized e-File platform (MeF).  
In this publication you will see references to detailed sections. These are noted by bold, black 
text and underlined. While this is not a live link to the document itself, you simply need to use 
your back button on your browser to return to the web page to find the actual link. There may be 
some embedded links in this document as well, that will allow you to open another document 
directly. These will be in blue text and underlined. 
Software development requirements are detailed within Publication 1346. The validation rules 
can be found in Publication 1347. The testing requirements are contained in Publication 1436. 
Administrative Highlights  
Please refer to the link on our Publication IND1345 (SP 275) webpage. 
Prior Year Filings  
Prior year 2018 and 2019 IND tax returns may be filed via the MeF platform with the following 
restrictions: 
•    Only software products that were certified to file the 2018 IT-40, IT-40PNR or IT-
     40RNR during the 2018 tax season may file the 2018 IT-40, IT-40PNR or IT-40RNR 
     during the 2020 tax season. 
•    Only software products that were certified to file the 2019 IT-40, IT-40PNR or IT-
     40RNR during the 2019 tax season may file the 2019 IT-40, IT-40PNR or IT-40RNR 
     during the 2020 tax season. 

The Federal/State Electronic Filing Program  
The Indiana Department of Revenue (department) accepts electronic tax returns as part of the 
Federal/State Electronic Filing program in conjunction with the Internal Revenue Service (IRS). 
The state system relies on the IRS to initially receive the state’s electronic data and store it until 
the department retrieves it for processing. Participants must meet all federal requirements as 
published by the IRS, as well as the requirements for the Indiana electronic filing program as 
specified in this publication. Indiana does accept unlinked returns for tax filings which cannot 
include the federal filing, but prefers that filings be linked whenever possible. Unlinked returns 
are more likely to experience processing delays in our back-end system. 
IRS Resources: e-Help desk assistors are ready to respond to Enrolled Agents, Reporting Agents, 
Electronic Return Originators, Certified Public Accountants, Software Developers, and 
Transmitters with non-account related questions and issues concerning e-products. The e-Help 
toll-free number is 1-866-255-0654. E-Help desk assistors support IRS e-file Individual and 
Business, EFTPS, SAM and e-services customers. 
Note: Callers who are outside of the 50 U.S. States and/or U.S. Territories should use the 
International phone number: 1-512-416-7750.

Who Can Participate  
There are three classifications of participants in the electronic filing program: Electronic Return 
Originators (ERO), Transmitters, and Software Developers. The electronic return originator 
(ERO) gathers forms from taxpayers and prepares them for electronic transmission using tax 
preparation software that has been approved by both the IRS and the department. They may be 
paid preparers who fill out the returns for the taxpayers or they may simply be drop-off points for 
the collection of completed returns which will be processed electronically.  

Transmitters send electronic returns directly to the IRS Service Center using approved software. 
A company may be both an ERO and a Transmitter, or an ERO may have an arrangement with a 
Third-Party Transmitter to use their computer services.  
Software Developers create and/or produce the tax preparation and transmission software which 
formats the electronic returns and allows the data to be transmitted via computers.  
The Application and Acceptance Process  
Because this is the Federal/State Electronic Filing Program, participants must meet the 
requirements of both the IRS and the State of Indiana to participate. To become an Authorized e-
file Provider, please visit the IRS website at www.irs.gov/Tax-Professionals/e-File-Providers-&-
Partners/Submit-Application . 
Once accepted into the federal electronic filing program, no additional Indiana application is 
needed. However, Indiana reserves the right to deny participation to any provider for reasons 
including outstanding tax liabilities, a failure to register your business in the state (when 
necessary), or a history of fraudulent transactions. Indiana reserves the right to terminate any 
partnership, for any reason, at any time and to stop accepting electronic returns from a provider.  
 
A Special Note for All EROs, Transmitters and Software Developers  
The software used to transmit the data must be approved by both the IRS and the department as 
part of the acceptance process. Software Developers are required to test their software programs 
for accuracy. The department will do additional testing of those programs prior to approving 
them.  
Indiana always encourages electronic filing wherever possible and welcomes new partnerships 
with software developers wishing to support Indiana in this endeavor. We encourage any 
developers who have not participated in MeF processing with Indiana previously to develop and 
test as early as possible. However, there are certain security measures that must be adhered to in 
order to begin testing. 
Specifications for developing software programs are explained in the IRS Publication 4164 
(MeF), Indiana Publication IND 1346 the Handbook for Developers of Electronic Filing 
Software for Individual Income Tax Returns, and Indiana Publication IND 1347, Edits and 
Validations for Indiana Individual Income Tax.  
Participating software developers will be provided with test data and instructions to perform the 
Indiana testing. Indiana’s testing procedure for the MeF platform is scenario based. Indiana

Publication IND 1436, Instructions for Testing Electronic Filing Software for Individual Income 
Tax Returns, contains all the necessary test materials for submitting Indiana test returns via MeF 
platforms. Only software developers are required to test with the department. However, EROs 
and transmitters must be sure to use only tax preparation software or use a third party transmitter 
whose software has been approved for use by the department. The department’s Tax 
Professionals web page provides a link to a listing of Certified Software Developers 
(https://secure.IN.gov/dor/3848.htm).  
The Indiana Department of Revenue reserves the right to suspend the approval of any software if 
a developer fails to comply with the DOR guidelines.

Attention: Do not distribute the Electronic Filing Coordinator’s telephone number to clients 
(i.e., taxpayers). This number is being provided to EROs as a courtesy. Distributing this number 
to the public can cause delays in assisting the EROs it was established to help.  
IRS Contacts 
Questions concerning your federal e-file application or regarding the federal e-file program may 
be directed to the IRS e-Help Desk at 1-866-255-0654 (toll-free). Callers who are outside of the 
50 U.S. States and/or U.S. Territories should use the International phone number: 1-512-416-

The Filing Process  
By electronically filing your individual income tax information, you avoid much of the 
paperwork associated with the filing process. Returns no longer have to be mailed, sorted, 
imaged, keyed, and verified. They bypass those parts of the process. 
 
Identity Theft Prevention 
The state of Indiana is requesting additional information in an effort to combat stolen-identity tax 
fraud and to protect our taxpayers’ hard-earned tax refunds.  Please provide the requested driver's 
license or state-issued identification card information whenever possible.  Returns will not be 
rejected if this information is not provided, but providing the information could help process the 
returns more quickly. 
 
What Can Be Electronically Transmitted  
The Indiana state individual income tax forms that can be electronically transmitted are:  
 •    IT-40, Indiana Full-Year Resident Individual Income Tax Return  
 •    IT-40PNR, Indiana Part-Year or Full-Year Nonresident  
 •    IT-40RNR, Reciprocal Nonresident Indiana  
 •    Prior Year: See details under “Prior Year Filings”

What Cannot Be Electronically Transmitted  
The following types of individual forms cannot be electronically transmitted.  
   • Amended or corrected returns (IT-40X) 
   • Returns for tax years prior to 2018 
   • The SC-40 Unified Tax Credit for the Elderly 
Giving Authorization to Discuss a Return 
A taxpayer may authorize the department to discuss his or her return with another individual by 
completing the Personal Representative Information and Authorization check box on Schedule 7 
(Form IT-40), Schedule H (Form IT-40PNR), or page 2 of Form IT-40RNR . To authorize the 
department to discuss a return with the paid preparer, the name of the individual paid preparer, 
not the firm, must be listed on the schedule/form as the personal representative. In addition, the 
personal representative authorization check box must be checked. 
 
Form IT-8879 Information 
An IT-8879, Declaration of Electronic Filing, must be completed and signed before transmission 
can take place. The IT-8879 serves several purposes. It gives authorization for the ERO to file on 
the taxpayer’s behalf and provide addition information to the department, provides permission 
for direct deposit of the taxpayer’s refund, and serves as authentication for the return.  
It is necessary to complete an IT-40, IT-40PNR, or IT-40RNR before filling out an IT-8879 
because the information needed on the IT-8879 will be taken directly from that return. The IT-
8879 should be printed for you by your tax preparation software.  
If the Paid Preparer is different than the ERO, and is not available to sign the IT-8879, a copy of 
the return signed by the Paid Preparer must be kept by the ERO with the completed IT-8879.  
Attachments to Form IT-8879.  
   • State copies of wage and withholding tax statements.  
   • Schedules, worksheets, or other verification requested on the main form (IT-40, etc.) to 
     explain any deductions and/or credits the taxpayer may have taken. These forms include, 
     but are not limited to:  
     o      IT-2210A, Annualized Income Schedule for the Underpayment of Individual 
            Estimated Tax  
     o      IT-2440, Disability Retirement Deduction;  
     o      IT-40NOL, Individual Net Operating Loss Schedule  
     o      Other State Tax Forms.  
     o      Any document requiring original signatures. If the primary paid preparer has NOT 
            signed the IT-8879, a copy of the main form (IT-40, etc.) with the signature be 
            attached.  
Note: Please attach the W-2 forms on the front of the IT-8879 where indicated. All other forms

Forms, schedules and/or letters should only be sent to the department upon request. 
If you have any questions concerning filling out the Form IT-8879, please direct them to the 
Indiana Electronic Filing Help Desk prior to transmitting the taxpayer’s information.  

The Transmission Process  
The data for the Indiana return must be transmitted to the Internal Revenue Service Center along 
with the federal return information. The Service Center simply receives and stores the Indiana 
information for the department to retrieve from them. Under no circumstances will the IRS alter 
the information on the state return.  

IRS Acknowledgments  
If the data meets the specifications and the transmission is accepted by the IRS, the transmitter 
will receive an acknowledgment that the transmission is complete. The IRS will acknowledge 
acceptance of the federal data and receipt of the state data packet. The IRS acknowledgment does    
not constitute acceptance (or rejection) of the Indiana data.  
If the data does not meet the IRS specifications, the entire packet (both the federal and state 
returns) will be rejected and an error code will be generated by the IRS. If an error code is 
generated, IRS Publication 1345 should be referenced.  

Indiana State Acknowledgments  
Indiana will use the IRS MeF Acknowledgment Schema to acknowledge receipt of the state data 
record transmitted. Specific error codes will indicate why the return was not accepted. Where 
appropriate, the schema path of the problem element will be identified. State Acknowledgments 
will normally post within 2 – 4 hours after the Transmitter has received the Federal 
Acknowledgments (exceptions: weekends and holidays).  
The State Acknowledgments will be addressed back to the Transmitter who sent the data. It is 
the Transmitter’s responsibility to retrieve the acknowledgment and inform the ERO or taxpayer 
that the return has been either accepted or rejected.  
In order to continue to participate in the Indiana Electronic Filing Program, all Transmitters are 
required to connect to the IRS at least once each day in order to retrieve any state 
acknowledgments. The department has the right to suspend any Transmitter from Indiana’s 
portion of the Federal/State Electronic Filing Program who fails to follow these guidelines.  
Please refer to the MeF Acknowledgment Schema on the IRS website, www.irs.gov

Indiana Business Rejection Error Codes  
It is important to note that, due to the flexibility afforded by XML, computation errors and 
duplicate return issues will be reason for reject and Transmitters will be notified of such error 
conditions. Therefore, a comprehensive list of Business Rejection Error Codes is available for 
electronic returns that were transmitted via the MeF platform. 
You may access the MeF Indiana Business Rejection Error Codes from the Federation of Tax 
Administrators (FTA) Secure Exchange System (SES) once they become available for 
publication. It is anticipated that Indiana’s Business Rejection Codes will be available for 
publication no later than mid-September. If you have activated the notifications to the FTA SES 
Indiana folders, you will automatically receive a notification email when the Business Rejection 
Error Codes are published.  

Indiana Schema Validation and Reject Process 
Indiana’s electronic return validation is a 2-part validation. 
•    Part 1 of the validation process is schema validation. If the return fails for any type of 
     schema violation, such as data formatting, the return will be rejected immediately, and no 
     further validation will be done. 
•    Part 2 of the validation process will be the business rejection rule validation. If the return 
     passes the business rule validations, it will be accepted by Indiana. If the return fails any 
     of the business rejection rules, it will be rejected. 
Transmitters who are sending returns that were generated by software products that do not 
validate against Indiana’s schemas can potentially see the same return rejected multiple times. If 
the return contains both schema and business rule violations, the initial acknowledgment(s) will 
identify only schema errors. Once the schema violations have been corrected, subsequent 
acknowledgments will report the business rule errors. 

Indiana Perfection Period Processing 
Indiana has a 5-day perfection period policy for electronically filed returns. Five days are 
allowed to perfect a rejected return for electronic re-transmission so that the return will be 
processed using the time stamp of the originally filed return rather than the time stamp of the re-
transmitted return. When a previously rejected electronic return is accepted by Indiana within the 
5-day transmission perfection period, it will be deemed to have been received on the date 
indicated in the time stamp of the first return submitted within that 5-day period.  
For purposes of the perfection period, the 5-day period is calendar days, not business days. 
This rule applies to all MeF rejected returns, but its implication is most important in regards to 
returns filed near or after the due date. Examples to illustrate how this rule will be applied 
follow. 
Note: The below table makes the assumptions that no federal or state extensions were filed and 
that the re-transmitted returns passed validation and were accepted by Indiana on that filing 
attempt.

Electronic Returns with Unreasonably Old Time Stamps 
Indiana will not accept electronic returns containing a time stamp that occurs more than five days 
in the past. 
Indiana concedes that there may be times when backlogs will occur due to processing problems 
at either the IRS or the Indiana Department of Revenue. During those times, Indiana will adjust 
the date threshold accordingly so as not to reject large numbers of returns that were delayed 
purely as a result of those processing issues. 
Once any backlogs are resolved, the normal threshold limitations will resume.

The following documents are not mailed to the department but must be maintained. Upon receipt 
of the Indiana acknowledgment, the ERO must keep and maintain the following information 
until December 31, three years after the return was signed and transmitted. For example: 2020 
return filed April 15, 2021: IT-8879 with attachments will be kept by the ERO until December 
31, 2024.) 
Each of the following must be kept by the ERO. You may retain either the paper or image 
format:  
•       Original IT-8879, Declaration of Electronic Filing w/original signatures;  
•       State copies of W-2s, W-2Gs, 1099-Rs, 1099-MISCs, 1099-Gs, IN-MSID-A and other 
        forms that show Indiana individual income tax withholding or unemployment 
        compensation;  
•       All documents requiring original, manual signatures;  
•       Any supporting schedules or worksheets that explain deductions or credits taken on the 
        return, as they apply to the taxpayer; and  
•       A copy of the IT-40, IT-40PNR, or IT-40RNR with the signature and business 
        information of the primary paid preparer only if they did not sign the IT-8879.  
Note  : Attach the W-2 forms on the front of the IT-8879 where indicated. All other forms or 
attachments should be attached to the back.  
The department may request copies of this information from the ERO on an as needed basis. The 
department, in return, will make every effort to review the records on hand before contacting the 
ERO for copies. However, the ultimate responsibility of record keeping falls to the taxpayer per 
IC 6-8.1-5-4(b).  
At the department’s discretion, random monitoring visits with EROs are possible in order to 
verify that they are complying with this procedure. Should an ERO decide to no longer remain in 
the business, the department must be notified in order to determine what will be done with the 
signature documents and attachments.  
If the ERO is a transient VITA or military site, special arrangements can be made for storage of 
the paper documents. Contact the electronic filing coordinator to make arrangements. Contact 
may be made via email at AltFileMgr@dor.in.gov or telephone at (317) 234-3660.  
Note: Do not give this telephone number to the taxpayer.)  
Corrections to Form IT-8879  
If the ERO makes changes to the electronic return after the taxpayer has signed Form IT-8879, but 
before the data has been transmitted to the IRS, the ERO must have the taxpayer complete a new 
IT-8879 if:  
•       The Federal Adjusted Gross Income (Form IT-40, Line 1) changes by more than $50 
        and/or  
•       The State Refund (Form IT-40, Line 16) changes by more than $14 

                                             12

Non-substantive changes are permissible on Form IT-8879 provided they meet the above 
conditions and are limited to:  
 •    Math errors                                                                                     Commented [BD3]:  
                                                                                                      Commented [BD4]: Arithmetic? Come on :) 
 •    Transposition errors 
 •    Misplaced entries 
 •    Spelling errors  
The ERO making the correction must initial any changes. If errors are found after the data has 
been transmitted and accepted, an IT-40X, Amended Return, must be mailed in for processing 
because amended forms are not accepted electronically. Amended forms with payments should             Commented [BD5]: This may change next Sept, talk to Cristen? 
be mailed to:  
      Indiana Department of Revenue 
      P.O. Box 7224 
      Indianapolis, IN 46207-7224  
 
All other amended forms should be mailed to: 
 
      Indiana Department of Revenue 
      P.O. Box 40 
      Indianapolis, IN 46206-0040 
 
Note: A State Only (Unlinked) Return cannot be used as a means for correcting or amending a 
previously filed return that was accepted by Indiana.                                                 Commented [BD6]: Again, not sure about next Sept. 

Due Date  
Transmission of electronic returns must be acknowledged by the IRS on or before April 15, 
2021, to be considered timely. The postmark date Indiana will recognize for all MeF filed returns 
is the ReturnHeaderState/Timestamp element. Indiana expects this element to contain the date 
and time of the tax return’s transmission to the IRS. 

Extended Filing  
Indiana will accept late returns electronically until the IRS closes the MeF gateway to prepare for 
the 2021 filing season. As with late paper returns, a Federal Extension for Tax Year 2020 must 
be filed with the IRS or a paper Form IT-9, Extension for Tax Year 2020 or an IT-9 extension 
electronically must be submitted to the department on or before April 15, 2021, to avoid penalty 
and interest. This requirement applies to all filings reporting a taxable income, even if a refund is 
due. Returns filed under a state or federal extension are due November 14, 2021.  

Taxpayer Copies  
After all necessary signatures have been obtained; the taxpayers must receive a copy of each 
form that applies to them.  
The taxpayers should receive copies of: their IT-8879, their IT-40, IT-40PNR, or IT-40RNR, and 
all of their supporting schedules. The originals will be kept by the ERO.

If the taxpayer has taxes due to the department, an official Post Filing Coupon (PFC) should be 
generated by the software and given to the taxpayer.  

Other Situations  
Credit Limits 
Some Indiana credits have annual limits, set by the Indiana General Assembly, regarding how 
much credit may be granted to taxpayers in aggregate during a given tax year. Taxpayers will be 
granted the credit until the maximum annual limit is reached for that tax year. From that point 
on, that credit will be denied on any return filed for that tax year that attempts to claim that 
credit. Once a credit reaches its maximum annual limit for a specific tax year, the department 
will post that information on the Software Developer’s website and will issue notices to all 
developers and transmitters who subscribe to our notification service. Unfortunately, there is no 
way for a taxpayer to know, when filing a return, if the credit will have exceeded its annual limit 
by the time the tax return is processed by the department. Obviously, the later in the filing season 
that the return is processed, the higher the likelihood that a limited credit will be denied. The 
denial of a credit will have the effect of reducing the taxpayer’s expected refund or increasing the 
amount owed. The taxpayer will be notified by letter if any credit on his return was denied due to 
legislative limits. 
Following is a list of the Indiana credits that have legislative limits and the amount of that limit. 
It should be noted that many of these credits have never actually reached the limits set by the 
Indiana Legislature; however, there is always the potential that it could happen during any given 
tax year. It should also be noted that the Indiana General Assembly sometimes adjusts the limits 
from one tax year to the next. For example, the limit for Credit 849 was $15,000,000 for Tax 
Year 2019, but it was increased to $16,500,000 for Tax Year 2020. 

Code                   Credit Description                  Limit Per Tax Year 
819           Historic Building Rehabilitation Credit                      $450,000 
823           Individual Development Account Tax Credit                    $200,000 
828           Neighborhood Assistance Credit                               $2,500,000 
831           Residential Historic Rehabilitation Credit                   $250,000 
835           Venture Capital Tax Credit                           $12,500,000 
849           School Scholarship Tax Credit                        $16,500,000 

These limits are not the annual limit. They are an “overall” limit. These credits will expire at 
whatever point the total credit amount allocated to them has been claimed. 
Refund Delays 
Refund checks will generally be processed, mailed, and in the taxpayer’s possession within three 
weeks of the department’s acknowledgment. However, if a delay does occur, taxpayers are 
advised to wait four weeks from the date of transmission before contacting the department to 
inquire about the status of a refund check.  
Taxpayers may inquire about the status of their state refund online or by calling the 
department’s Automated 

                                             14

Refund Line at (317) 233-4018. With either process, the taxpayer will need to provide their 
Social Security Number, the tax year (not date filed), and the exact refund amount claimed on the 
return.  
Do not give your clients the E-File Coordinator’s number to inquire about their refunds. That 
number was established to expedite assistance to EROs. Additional calls on this line can cause 
delays in assisting the EROs it was established to help.  
Refund amounts may be offset by any outstanding liabilities due to the department, another state 
agency, or the IRS for any reason. These outstanding liabilities may delay processing of a 
taxpayer’s refund because all claims against that refund must be resolved before a refund check 
can be processed. This is the same procedure the department follows with paper returns.  
 
Refund Anticipation Loans (RAL)  
Refund Anticipation Loans are not offered by the department. Taxpayers must wait until their 
returns are processed to receive any refunds due to them. If the ERO enters into an RAL 
agreement with the taxpayer, it is the responsibility of the ERO to explain exactly how the 
taxpayer may expect to receive their refund. The ERO should not expect special treatment from 
the department on any RAL agreement that they have entered into with the taxpayer.  
 
Direct Deposit  
Indiana taxpayers can elect to have their Indiana refund direct deposited into their Checking, 
Savings, or Hoosier Works accounts. Refunds will only be direct deposited if Sections II & III of 
the IT-8879 have been completed and signed by the taxpayer. The ERO must ensure that the IT-
8879 has been properly completed and signed by the taxpayer. The department cannot make any 
changes to this information after the return is filed. 
Taxpayers may have their refund direct deposited into their Hoosier Works MasterCard account. 
If a client is eligible and wishes to deposit their refund into their Hoosier Works MasterCard 
account, place the taxpayer’s 12-digit Hoosier Works account number from their monthly 
statement in the Account Number area. Enter “021031207" in the Routing Transit Number area. 
Check the Hoosier Works MC box:  
(Type of Account:   Checking      Savings       Hoosier Works MC)  
Note:Do not use the 16-digit MasterCard number. Use the taxpayer’s 12-digit Hoosier Works 
account number from their monthly statement in the Account Number area.

The taxpayer may elect to have their 2020 overpayment: 
 • Applied to the Indiana Nongame Wildlife Fund, Military Family Relief Fund and/or 
   Public K12 Education Fund; 
 • Applied to their 2021 estimated tax; 
 • Issued in the form of a check; 
 • Directly deposited into their financial institution; or  
 • The taxpayer may elect to have their refund split in the following manner:  
         o Part applied to the Indiana Nongame Wildlife Fund, Military Family Relief Fund 
           and/or Public K12 Education Fund and the remainder refunded by check or by 
           Direct Deposit; or  
         o Part applied to their 2020 estimated tax account and the remainder refunded by 
           check or by Direct Deposit.  
Neither the Indiana Department of Revenue nor the Financial Management Service (FMS) is 
responsible for the misapplication of a direct deposit that is caused by error, negligence, or 
malfeasance on the part of the taxpayer, ERO, transmitter, software developer, financial 
institution or any of their agents.  
Special Note about Direct Deposit: It is important to note that the Indiana State Auditor’s 
Office uses BMO Harris Bank to perform direct deposit functions. When your client is checking 
to see if a refund has been direct deposited into their account, tell them that it may appear under 
either Indiana Department of Revenue OR BMO Harris Bank. It may also appear as a “credit” 
rather than a “deposit. We recommend the taxpayer talk directly with the ACH section in the 
accounting department of their financial institution about transactions of this sort; normally 
tellers only have access to information about transactions made within the previous two-week 
period.  
Direct deposit refund requests rejected by the taxpayer’s financial institution will be mailed to 
the address supplied on the return in the form of a paper check. This process can delay the 
taxpayers refund up to 5 weeks.  
Paper refunds will be mailed directly to the taxpayer. Refunds needing to be sent to any other 
person or address (e.g., Power of Attorney) cannot be transmitted electronically.  
 
Balance Due Returns  
All electronic filers who owe taxes will need to submit their payment to the department via 
electronic payment or with a Post Filing Coupon (PFC), which indicates where the payment 
needs to be applied. Taxpayers must submit payment prior to the due date to avoid additional 
penalty and interest.

Entries on the Form IT-40 or Form IT-4PNR, requesting allocation as a 2020 estimated tax 
payment will be disallowed when the taxpayer is currently in a balance due status. If the taxpayer 
is in a balance due status and wishes to make a 1st installment period 2020 estimated tax 
payment, the taxpayer must use Form IT-40ES, Form ES-40 Or make an online payment via 
https://dorpay.dor.in.gov/.  
The issuance of the PFC will be the responsibility of the ERO. The ERO is responsible for 
explaining to the taxpayer when and how to file the PFC and/or make payment via the electronic 
payment system. 
If not paid by the April 15, 2021 payment deadline, as with all late balance due returns, penalty 
and interest will be assessed. There are three options available: 
•     Payment, including penalty and interest, may be made in the form of a check or money 
      order; contact the Practitioner’s Hot Line at (317) 233-4017 to determine the amount of 
      penalty and interest due. If the PFC is being submitted with the payment after the due 
      date, penalty and interest should be included with the “Amount You Owe” in the 
      designated box on the PFC.  
•     Payment, including penalty and interest, may be made using an electronic payment 
      method at www.in.gov/dor/4340.htm. See other payment options below for credit card 
      and electronic echeck.  
•     The department will send a Demand Notice for Tax Due billing to the address shown on 
      the electronically filed tax return. 
 
Other Payment Options 
Credit Card Payments 
The taxpayer may make a payment with a major credit card by logging on to the department’s 
website at www.in.gov/dor/4340.htm. Major credit cards that are accepted are MasterCard and 
VISA. 
Electronic Payment Systems  
Electronic options allow the taxpayer to make payment by having the payment debited directly 
from their bank account. To take advantage of this payment option, the taxpayer will visit our 
website at www.in.gov/dor/4340.htm. See the website for additional information. 

Responsibilities of EROs and Transmitters  
Electronic return originators and transmitters must abide by the terms set forth in this 
publication, the IRS Publication 1345, IRS Publication 4164 & Supplements and must maintain a 
high degree of integrity, compliance, and accuracy in order to continue to participate in the 
Federal/State Electronic Filing program.  
Transmitters must ensure that electronic returns are filed in a timely manner. The date contained 
in the ReturnHeaderState/Timestamp element will be considered the post mark date for 

                                           17

electronically transmitted Indiana returns. Transmitters must forward state acknowledgments to 
EROs on a timely basis.  
EROs must ensure that the original Submission ID is clearly and completely written or printed in 
the upper right-hand corner of the IT-8879 in the space provided. If not available at time of 
signing, it should be available to be completed if the department requests this form. W-2, W-2G, 
and 1099 forms must be attached to the front of the IT-8879. All other documentation must be 
attached to the back of the IT-8879.  
EROs must keep and maintain the original signed IT-8879 for a period of three (3) years from 
December 31 of the year in which the document was signed and electronically transmitted.  
It is the transmitter’s responsibility to confirm acknowledgment of the return by the department 
before considering the state portion received. When making an inquiry on the status of an 
electronically filed return, have the state acknowledgment date available.  
If the taxpayer elects to designate a personal representative to discuss their tax return with the 
department, the ERO must inform the taxpayer how they may revoke the authorization with the 
department to discuss their tax return with the personal representative. 
The department reserves the right to suspend any transmitter or ERO from the program if they do 
not follow the guidelines set forth in this or any other federal or state publication concerning the 
Electronic Filing program.
