                 Credit for Income Taxes Paid to Other Jurisdictions  
                                              (Wage Income) 
                                        Understanding Income Tax 

Purpose of This Publication 

Resident taxpayers who paid Income Tax both to New Jersey and to an out-of-state jurisdiction    in the same tax 
year may be eligible for a credit against the tax they owe to New Jersey. A taxpayer can be an individual, an 
estate, or a trust that pays Income Tax to another jurisdiction. The income can be earned from a business, an S 
corporation, or through self-employment. 

This publication explains: 

    • How to determine what income you can include in the credit calculation; 

    • When you are eligible to claim a credit for taxes paid to another jurisdiction;  

    • How to calculate the credit amount you are eligible to claim. 

The examples provided illustrate how to determine the tax credit in both simple and complex situations.  

(See our companion publication, Credit for Taxes Paid to Other Jurisdictions (Business/Nonwage Income), 
for examples of how to calculate the tax credit on business/nonwage income.) 

Purpose of the Credit 

This credit minimizes double taxation of income that is already taxed by other jurisdictions. Your credit will either 
be the amount of New Jersey Income Tax that you would have paid if the income had been earned in New Jersey, 
or the amount of tax actually paid to the other jurisdiction, whichever is less. 

These are the statutory limitations: 

 1. The income must have  been taxed, in the same tax year, by       both        New Jersey and another qualified 
      jurisdiction (see Jurisdiction ); and   

 2. The credit cannot exceed the proportional credit limitation. (See            Proportional Credit Limitation 
      Formula. ) 

Components of the Credit Calculation 

Before you can calculate any credit for taxes paid to another jurisdiction(s), you must understand the components 
of the credit calculation. You must also know how to determine each of those components for each jurisdiction 
and for each tax that you are claiming a credit. You must determine: 
                                                                                                    GIT-3W 
                                                                                                     January 2022

Credit for Income Taxes Paid to Other Jurisdictions
(Wage Income)
Understanding Income Tax

• What constitutes a jurisdiction ;

• Income actually taxed by the other jurisdiction;

• Income properly taxed by another jurisdiction;

• Income actually taxed by both New Jersey and the other jurisdiction;

• Income taxed by New Jersey;

• Actual tax paid to the other jurisdiction.

Jurisdiction
This is any state of the United States other than New Jersey, a political subdivision (e.g., county or municipality)
of any state other than New Jersey, or the District of Columbia. You are not allowed to claim a credit for taxes
paid to the U.S. government, Canada, Puerto Rico, or to any foreign country or territory.

Income Actually Taxed by Another Jurisdiction
Generally, this is the income sourced to the other jurisdiction, after any adjustments allowed by the other
jurisdiction but before deducting personal exemptions and standard or itemized deductions.

Income Sourced to Another Jurisdiction v. “Worldwide Income”
Some jurisdictions require you to determine the actual amount of tax due. First, you calculate a base tax on your
total income from all sources (worldwide income) as if you were a resident of that state. Second, divide the
amount of income sourced to the other state by worldwide income, which gives you a percentage. Then, multiply
the base tax by the percentage you calculated.

This method of tax calculation may result in you having higher tax liability in the other jurisdiction. However, it
does not increase the amount of income subject to tax by the other jurisdiction. The other jurisdiction actually
taxes only the income sourced to that state, and not worldwide income. (See example 6.)

As the New Jersey Tax Court stated in Chin v. Director, 14 NJ Tax 304 (Tax Ct. 1994): “It is clear that the use of the
plaintiff’s non-New York income in determining the tax rate to be imposed on his spouse’s New York source
income did not constitute taxation of that non-New York income. Accordingly, the Director properly excluded
the non-New York income from the numerator of the resident credit fraction because it was not subject to tax in
New York….”

The worldwide income is used to determine the tax rate to be imposed on income sourced to the jurisdiction,
but not actually taxed. Thus, only income actually sourced to the other state can be included on line 1, Schedule
NJ-COJ. (See Chin v. Director .)

Credit for Income Taxes Paid to Other Jurisdictions
(Wage Income)
Understanding Income Tax

Income Allocations Allowed by the Other Jurisdiction
A jurisdiction may allow income to be allocated when it is earned partly inside and partly outside the state. For
example, wages may be allocated using a ratio of days worked in the state over days worked everywhere. Since
the allocation of time worked in the state reduces the wages taxed by the other jurisdiction, you must take that
into consideration when determining the income actually taxed by the other jurisdiction. (See example 7.)

Adjustments (Deductions) Allowed by the Other Jurisdiction
In some cases, a jurisdiction does not allow subtractions or deductions from income. Do not include on line 1,
Schedule NJ-COJ any expenses allocated to the other jurisdiction that were used to reduce the income on line 2
but were not allowed in the other jurisdiction. Examples can include interest paid to finance the purchase of an
interest in a partnership and expenses paid by the partner that were not reimbursed by the partnership. They are
not permitted as deductions in some states, but can be used to reduce taxable income in New Jersey. (See
example 8.)

Income Subject to Tax by More Than One Jurisdiction Within One State
You can report income only once on the Schedule NJ-COJ. You can make only one credit calculation on Schedule
NJ-COJ when the same income is taxed by one or more jurisdictions within the same state, and the amount of
income taxed by each jurisdiction is the same. (See example 4.)

When the same income is taxed by one or more jurisdictions within the same state and the amount of income
taxed by each jurisdiction is different, you must use separate Schedule NJ-COJ’s to make your calculations. One
credit is based on the amount of income taxed by all the jurisdictions. The other credit is based on the difference
between the amounts taxed by each jurisdiction (excess income).

For example, you earned wages of $15,000 in a city in another state. After adjustments, $9,000 of that income
was taxed by the other state. However, the entire $15,000 was taxed by the city. The amount of excess income is
$6,000. In such a case, you must make two credit calculations. The first calculation determines the credit allowed
on the $9,000 taxed by all the jurisdictions; the second calculation determines the credit allowed on the $6,000
of excess income. (See example 9.)

Income Properly Taxed by Another Jurisdiction
You can include only income properly taxed by another jurisdiction in the credit calculation.

Income Properly Taxed
In general, another jurisdiction may properly tax a nonresident’s income from:

• Services rendered within that jurisdiction;

                                               (Wage Income) 
                                       Understanding Income Tax 

   •   Net profits from a business, trade, or profession carried  on within that jurisdiction, including interest 
       earned by the business, etc.; 

   •   A partnership or S corporation as allocated to that jurisdiction; 

   •   Real property (such as real estate) or tangible personal property (such as furniture, jewelry and art) located 
       in that jurisdiction; 

   •   Gambling in that jurisdiction; 

   •   Estate or trust distributions that were derived from any of the above types of income located, allocated, 
       or rendered within that jurisdiction. 

Income Not Properly Taxed 
A nonresident’s personal income from interest, dividends, or gains from intangible personal property is not  
properly taxable by another jurisdiction. If you are a nonresident, income from interest, dividends, or gains from 
intangible personal property (such as life insurance or securities investments) that was derived from a business, 
trade, or profession carried on in the other jurisdiction   properlyistaxable by that jurisdiction. For example, 
interest on a personal savings account in a bank located in another jurisdiction is not properly taxable by that 
jurisdiction. In addition, other jurisdictions cannot tax you on most retirement benefits, including distributions 
from deferred compensation plans, (e.g., 401(k) Plans, 457 Plans) and IRAs. (See example 10.)  

If you reported and paid tax to another jurisdiction on income not    properly taxable by that jurisdiction, you must 
follow the other jurisdiction’s procedures for requesting any refund due. 

Dual State Residents 
If you are considered to be a resident of both New Jersey and another state for the same period, you can claim 
a credit based on all income taxed on both the New Jersey and the other state’s resident returns, except     for any 
income allocated to New Jersey. For example, any S corporation or partnership income allocated to New Jersey 
cannot be included in the credit calculation. 

When the same income is reported to two states, other than New Jersey, that income is included only once on 
Schedule NJ-COJ.  

Example: An individual is a resident of both New York and New Jersey and has a business in Connecticut. They 
pay tax to Connecticut on their business income. They must also report that income on both the New Jersey and 
New York resident returns. They must claim a credit on the New York return for the tax paid to Connecticut. They 
also must claim a credit on the New Jersey return for the tax paid to Connecticut. They cannot claim a credit for 
New York tax because they did not pay tax to New York on this income. 

                                                                                                            GIT-3W 
                                                                                                        January 2022

                Credit for Income Taxes Paid to Other Jurisdictions

                                     Understanding Income Tax 

Income Actually Taxed by Both NJ and Another Jurisdiction 
Income Taxable in Another Jurisdiction Exempt From Tax in NJ 
Income must be taxed by both New Jersey and the other jurisdiction to be included on Schedule NJ-COJ. For 
example, unemployment compensation may be taxed by another jurisdiction but it is not taxable by New Jersey 
so you cannot include this income on line 1 of Schedule NJ-COJ. 

Other Jurisdiction’s Additions to Income 
The other jurisdiction may require additions to income that are not required by New Jersey and, therefore, are 
not reported on the New Jersey return. For example, a depreciation adjustment might be added to the business 
income taxed by the other jurisdiction. However, if the adjustment is not required or reported on the New Jersey 
return, it cannot be included in the credit calculation. (See Adjustments (Deductions) Allowed by the Other 
Jurisdiction .) 

Income Taxed by New Jersey 
Enter on Schedule NJ-COJ, line 2, the New Jersey Gross Income amount reported on Form NJ-1040, line 29. This 
is the total of all income reported on the New Jersey return after any  pension or other retirement income 
exclusion but before exemptions and deductions. (See example 1.)  

Actual Tax Paid to the Other Jurisdiction 
The actual tax paid to the other jurisdiction is the amount of tax that is due after deducting all tax credits allowed 
by that jurisdiction (e.g., child and dependent care, new job, research and development), but before the deduction 
of any payments made, such as withholdings, estimated payments, extension payments, or an overpayment from 
a prior year. 

If the same income was taxed by both a state and a jurisdiction within that state, the actual tax paid is the total 
tax paid to the state plus the tax paid to the jurisdiction on that income. 

Actual Tax Paid on Income Taxed by More Than One Jurisdiction in a State Outside NJ 
There may be situations in which a state and one or more jurisdictions within that state tax differing amounts of 
income. When calculating a credit in those instances, you must complete a separate Schedule NJ-COJ for each 
jurisdiction. You can report only the actual tax paid to the other jurisdiction(s) on the amount of income reported 
on line 1 of your Schedule NJ-COJ. To prorate the tax paid to the other jurisdiction, divide the amount of income 
on line 1 by the total amount of income taxed by that jurisdiction. Apply the resulting percentage to the total tax 
paid to the other jurisdiction. (See example 9.) 

                                                                                                  GIT-3W 
                                                                                              January 2022 
                                                                                                          7

Credit for Income Taxes Paid to Other Jurisdictions
(Wage Income)
Understanding Income Tax

How to Claim the Credit

You must do the following to claim credit for taxes paid to another jurisdiction:

1. Complete Schedule NJ-COJ in its entirety. You may have tocomplete more than one Schedule NJ-COJ
in certain situations. Fiduciaries of a resident estate or trust must complete Schedule C, Form NJ-1041;

2. Complete Worksheet I in the NJ-1040 Instructions if eligible to receive a property tax deduction or credit;

3. Enclose Schedule NJ-COJ(s) with the NJ-1040 Income Tax return.

Proportional Credit Limitation Formula

The proportional credit limitation (PCL) amount represents the amount of Income Tax New Jersey would have
imposed if the income you earned in the other jurisdiction had been earned in New Jersey.

The PCL is calculated by dividing the income actually taxed by both New Jersey and the other jurisdiction (a) by
the income subject to New Jersey tax (b). Multiply the resulting percentage by the tax calculated on the total
New Jersey taxable income (c). The formula is:

a
b × c = PCL

You then must compare the PCL amount to the actual tax paid to the other jurisdiction. You can claim a credit of
the lesser of the two amounts. (See examples 2and .)3

Completing More Than One Schedule NJ-COJ

Complete a separate Schedule NJ-COJ for each jurisdiction for which you are claiming a credit, or for each tax
imposed by a jurisdiction. You must file separate schedules when:

• Two or more jurisdictions (i.e., a state and political subdivision(s) therein – such as counties or
municipalities) tax the same income.For example, when both a state and a city within that state tax the
same income, you may have to complete and enclose a separate Schedule NJ-COJ for each jurisdiction.
(See example 4);

• Different jurisdictions tax different income. For example, if you had wages from State A and a gain from
the sale of property from State B, you must complete a separate Schedule NJ-COJ for each state;

                                            (Wage Income) 
                                    Understanding Income Tax 

 •  The same jurisdiction imposes more than one type of tax.  For example, if you had wages and business 
    income from a city that imposes both a wage tax and a different tax on business income,  you must 
    complete one Schedule NJ-COJ for the wage tax and a separate Schedule NJ-COJ for the tax on business 
    income. 

Part-Year Residents 

A part-year resident is a New Jersey resident for only part of the tax year. If you are a part-year resident who is 
required to file a New Jersey Resident Income Tax return, you must report on that return all the income received 
during your period of New Jersey residency, whether the income was from inside or outside New Jersey. If you 
received income from New Jersey sources during your period of nonresidency, you also may be required to file 
a part-year nonresident return with New Jersey. (See Part-Year Residents and Nonresidents to determine if 
you need to file a return.) 

Part-year residents may be able to claim a credit for taxes paid to other jurisdictions. You must have been a part-
year resident who paid Income Tax both to New Jersey and to an out-of-state jurisdiction on income that is 
reported on the part-year resident return. You may be eligible to claim a credit as long as the income was derived 
from the other jurisdiction during the period of time you were a New Jersey resident, and is actually and properly 
subject to tax in both the other jurisdiction and New Jersey. As a part-year resident, you should use the same 
criteria and methodology as full-year residents to determine the components of the credit calculation and the 
credit amount. 

For more information on the filing responsibilities of part-year residents and part-year nonresidents, see the 
instructions for the New Jersey resident return (Form NJ-1040) and nonresident return (Form NJ-1040NR), or 
see Part-Year Residents.  (See examples 11 and 12.) 

Income From New York 

If you are a New Jersey resident who works in New York or earns other taxable income there, you are often taxed 
on an amount less than your actual New York source income as a result of the deductions allowed by New York. 
When calculating a credit for taxes paid to New York, you should only use the income actually taxed by New York 
in the calculation. Because of New York’s method of calculating a nonresident taxpayer’s tax, it is not possible to 
identify one particular line on the New York tax return that represents the income subject to tax in New York.  

Do not use the  “worldwide income” column in the credit calculation.  (See    Income Sourced to Another  
Jurisdiction v. “Worldwide  Income” .) 
                                                                                                  GIT-3W

          Credit for Income Taxes Paid to Other Jurisdictions  
                                          (Wage Income) 
                                     Understanding Income Tax 

Follow the New York State Nonresident Return (Form IT-203) instructions carefully to ensure that you include the 
correct items and amounts of income in the New York State Amount column. If you complete the New York IT-
203 correctly, the income (or loss) reported in the New York State Amount column will only include income 
earned from sources in that state and properly taxable to that state. 

Items such as interest earned from a New York bank account or dividends paid by a New York corporation are 
not taxable in New York unless such income is from property used as part of trade, business, profession, or 
occupation carried on in that state. 

Income From Pennsylvania 

Pennsylvania and New Jersey have a Reciprocal Personal Income Tax Agreement. That means wages, salaries, 
and other compensation paid to New Jersey residents employed in Pennsylvania are not subject to Pennsylvania 
income tax. Residents of each state pay taxes to their state of residency, not to the state where they work. Thus, 
a New Jersey resident cannot claim a credit for taxes paid to Pennsylvania on employee compensation because 
the earnings are not subject to tax in Pennsylvania. 

If you are a New Jersey resident, and Pennsylvania tax is withheld from your wages in error, you must file a 
Pennsylvania nonresident return to receive a refund. To stop the withholding of Pennsylvania income tax, you 
must complete a Pennsylvania Employee’s Nonwithholding Application Certificate (Pennsylvania Form REV-
419) and give it to your employer. You can get this form from the Pennsylvania Department of Revenue. 

The Reciprocal Agreement covers only  employee compensation (wages, tips, fees, commissions, etc.). If you are 
self-employed or receiving income other than wages (e.g., gain from the sale of property) that is taxable in both 
states, you can claim a credit for taxes paid to Pennsylvania on that income. We do not allow a credit for taxes 
paid in error to Pennsylvania on employee compensation. (See example 13.) 

Income From Pennsylvania Municipalities 
The New Jersey/Pennsylvania Reciprocal Agreement does not apply to the income or wage tax imposed and 
collected by the City of Philadelphia or any other municipality in Pennsylvania. Therefore, you can include in the 
credit calculation income subject to both New Jersey Income Tax and the wage or income tax imposed by a 
Pennsylvania municipality. 

Wages From Philadelphia 
New Jersey residents earning wages in Philadelphia can determine the income to enter on line 1 of Schedule NJ-
COJ, by dividing the wage tax deducted (as reported in the “Local income tax” box on the W-2) by the Philadelphia 
nonresident tax rate as follows: 
                                                                                                 GIT-3W

                     Philadelphia Wage Tax Paid* 
                    Philadelphia Wage Tax Rate    =  Line 1, Schedule NJ-COJ 

The amount reported on line 1 cannot be more than the amount of Philadelphia wages included on line 15, Form 
NJ-1040. You must use the exact amount of Philadelphia wage tax reported on the W-2 when performing this 
calculation. Do not round the figure either up or down. (Seeexample 14.) 

In addition, if you contribute to a 401(k) Plan, you may need to adjust line 1 and box 9a of Schedule NJ-COJ. 

Unlike wages reported for New Jersey tax purposes, the amount of wages reported for Philadelphia include the 
401(k) amount. Accordingly, wages from Philadelphia that are available for a credit from New Jersey must be 
decreased for the Schedule NJ-COJ using the following calculations:

                                       Understanding Income Tax 

Therefore, you must adjust the tax paid to Philadelphia to reflect the amount of income eligible for a credit. Then, 
you can determine the maximum credit allowed using the following calculation: 

        Income Eligible for Philadelphia 
        Income Taxed by Philadelphia            =  Percentage of Philadelphia income eligible for credit 

        Percentage of Philadelphia income Eligible for Credit 
        × Taxes paid to Philadelphia________                        ___ 
        Prorated Taxes paid to Philadelphia – Enter this amount on Schedule NJ-COJ, box 9A 

Refund of Wage Tax Paid to Philadelphia  
If you filed a Philadelphia Petition for Wage Tax Refund, you must subtract your refund from the Philadelphia 
wage tax paid: 

               Taxes Withheld for Philadelphia 
               (Less Refund)___________________ 
               Total Taxes Paid to Philadelphia – Enter this amount on Schedule NJ-COJ, box 9A 

Divide Total Taxes Paid to Philadelphia by the Average Philadelphia Tax Rate (3.5019%) to determine the income 
taxed by Philadelphia. Report this income on line 1 of Schedule NJ-COJ. 

If you file the Philadelphia Petition for Wage Tax Refund after you file your NJ-1040 and you receive a refund of 
Philadelphia withholding, you must file an amended return, Form NJ-1040X, with the corrected wages and taxes 
paid, as calculated above. 

Changes Due to Audit by Other Jurisdictions 

When an audit by another jurisdiction changes the amount of previously reported tax paid, it will result in an 
adjustment to the credit you claimed on your New Jersey return. You are required to file an amended New Jersey 
return, Form NJ-1040X, for the year(s) affected by the audit and pay any amount due. If the audit results in an 
overpayment, you can request a refund “regardless of any otherwise applicable statute of limitations,” provided 
you claimed the credit for that state or municipality on your original return. N.J.S.A. 54A:4-1(e).  

                                                                                                         GIT-3W

                                   Understanding Income Tax 

If You Are Audited By New Jersey 

New Jersey does not require you to enclose a copy of the income tax return(s) filed with the other jurisdiction(s) 
if you file a paper return. However, you should keep complete copies of any returns filed with other jurisdiction(s). 
If we audit your return, you will be asked to provide: 

 (a) A complete copy of the income tax return(s) filed with the other jurisdiction(s), if one was filed or required 
     to be filed, along with  schedules, worksheets, etc., that show the nature and source of the income being 
     taxed;  

 (b) Documentation to prove you participated in a composite return filed in another jurisdiction. This can 
     include a statement on the filing entity’s letterhead that lists the jurisdiction, your share of the income 
     taxed by the other jurisdiction, and your share of the tax paid; 

 (c) The following if you were not required to file a return with the other jurisdiction:  

     • A W-2 that lists the wage taxes paid and the name of the taxing jurisdiction;  

     • A statement from the business entity that filed a tax return based on income that lists your share of 
       the income taxed by the other jurisdiction. It should include the name of the tax, and your share of the 
       tax paid (e.g., Philadelphia Net Profits Tax, New York City Unincorporated Business Tax). 

Estimated Tax Payments 

Individuals and certain estates and trusts who expect their New Jersey Income Tax liability to be more than $400 
are required to make quarterly estimated tax payments. Use Form NJ-1040-ES to file estimated tax payments 
when due. (For more information on estimated taxes, see Estimating Income Taxes.)  

Jurisdiction Code 

If you are a New Jersey resident claiming a credit, you are required to enter on line 43, Form NJ-1040, a two-digit 
code for the jurisdiction for which you are claiming a credit. For more information see the NJ-1040 instructions.

                 Credit for Income Taxes Paid to Other Jurisdictions  
                                         (Wage Income) 
                               Understanding Income Tax 

 Example #4 – Determining the credit for income taxed both by another state and by a 
                 city within that state  when the state and city  are taxing the same 
                 amount of income. 
 A married couple files jointly, and are full-year New Jersey residents. One individual earned $15,000 in New 
 Jersey, and the other earned $30,000 in a city located in another state. The income actually taxed on the 
 nonresident return for the other state was $30,000, and the tax paid to the state on that income was $1,600. 
 The nonresident income actually taxed by the city was $30,000, and they paid $135 in city tax. 

 Income only can be reported once on line 1, Schedule NJ-COJ. Even though the one individual paid tax to 
 two jurisdictions, they complete only one Schedule NJ-COJ to calculate their credit. The total tax paid to both 
 the state and the city, $1,735, is compared to line 8, Schedule NJ-COJ to determine the credit. 

 They are eligible for either a property tax deduction or credit. They must first complete lines 1 and 2 of 
 Worksheet H to determine their property tax deduction amount. Then they will complete both columns A 
 and B of Schedule NJ-COJ in addition to Worksheet I.

                               Understanding Income Tax 

  Example #5 – Determining the credit when income is taxed by two different states 
                 outside New Jersey. 
  A married couple file jointly and are full-year New Jersey residents. One individual earned wages of $52,000 
  in New York State. Their New York taxable income (from their nonresident return Form IT-203) was $50,500, 
  and they paid tax of $2,600 to New York. The other individual worked in Delaware, where they earned wages 
  of $38,000 and paid $930 in Delaware income tax. They are not eligible for a property tax deduction/credit. 

  Because they are claiming a credit for taxes paid to more than one jurisdiction, they must complete two 
  separate Schedules NJ-COJ: one for New York State and one for Delaware. They will only complete column B 
  of each schedule as if no other state were involved.  

  To determine the total credit for taxes paid to other jurisdictions for line 43, Form NJ-1040, they add the 
  amounts from line 9, column B of each Schedule NJ-COJ. 

                                                                 Income Subject to Tax

                 Credit for Income Taxes Paid to Other Jurisdictions  
                                         (Wage Income) 
                               Understanding Income Tax 

  Example #6 – Determining line 1, Schedule NJ-COJ when the other jurisdiction uses 
                 income from all sources to determine the tax due. 
  Two individuals are married and New Jersey residents. One works in New York, and their salary is $65,000. 
  The other works in New Jersey, and their salary is $35,000. They also have income from interest, dividends, 
  and capital gains. Although only the first individual’s salary is subject to tax by New York, they must determine 
  their New York tax liability as if they were New York residents. First, they must calculate the tax on their total 
  income from all sources (federal amount). Then, they must multiply the resulting “base tax” by the proportion 
  that their total New York source income (the New York salary) bears to their total income from all sources.  

  Determining the tax liability of a nonresident in this manner may result in an increase in the average tax rate 
  for income derived from the other jurisdiction. However, it does not affect the amount of income actually 
  being taxed by the other jurisdiction.

  A resident taxpayer who works in another state is required to work one day each week in New Jersey. Their 
  total wages for the year were $125,000. Their W-2 showed all the income was earned in the other state; it did 
  not reflect the days worked in New Jersey. They must allocate their total wages between the other jurisdiction 
  and New Jersey based on the percentage of time worked in each locality. Line 1, Schedule NJ-COJ is limited

  Example #8 – Determining line 1, Schedule NJ-COJ when the other jurisdiction allows 
                 an adjustment to (reduce) income that is not allowed by New Jersey. 
  A New Jersey resident taxpayer, works in New York where they earned wages of $115,000. They paid alimony 
  of $20,000. In New York, the alimony payment is an adjustment to income that reduces line 1, Schedule NJ-
  COJ, whereas in New Jersey, the alimony is a deduction and does not reduce line 2, Schedule NJ-COJ. (Line 
  2, Schedule NJ-COJ includes New Jersey income from all sources after subtracting any applicable pension 
  and/or  other  retirement  income  exclusion  allowed  by  New  Jersey,  but  before  subtracting  any  personal 
  exemptions or deductions such as alimony payments.)  

  The schedule below shows how to determine the amount of income subject to tax in both jurisdictions when 
  there is an adjustment to income allowed by the other jurisdiction.

 Example #9 – Determining the credit for income taxed both by another state and by a 
                city within that state when the city taxes more income than the state. 
 A married, full-year resident couple files jointly. One earned wages of $15,000 in New Jersey. The other 
 worked in a city located in another state, where they earned wages of $30,000. The other state taxed $20,000 
 of their income, and they paid tax of $1,600 to that state. The city taxed $30,000 of their income, and they 
 paid $135 in city tax.  

 They must complete two separate Schedule NJ-COJs: one for the amount of income that was taxed by both 
 the other state and city, and one for the amount of income taxed only by the city (excess income). The total 
 credit allowed is the sum of the two separate Schedule NJ-COJ calculations. 

 They are not eligible for a property tax deduction or credit and complete only column B of each Schedule 
 NJ-COJ.

Credit for Income Taxes Paid to Other Jurisdictions
(Wage Income)
Understanding Income Tax

Example #9 – continued

(a) Credit for taxes paid on the amount of income taxed by both the state and city.

They enter $20,000 on line 1 of the first Schedule NJ-COJ. This is the amount of income taxed by both
jurisdictions. The entry on line 9 is the lesser of the amount on line 8 (the proportional credit limitation
amount for $20,000) or the amount from box 9a (the total tax actually paid to both the state and the city on
$20,000).

The tax actually paid to both the state and the city on $20,000 is $1,690 ($1,600 paid to the state + $90 paid
to the city). They calculate the tax paid to the city on $20,000 as follows: $135 × ($20,000 ÷ $30,000) = $90.

Credit for Income Taxes Paid to Other Jurisdictions
(Wage Income)
Understanding Income Tax

Example #9 – continued

(b) Credit for taxes paid to the city on income taxed by the city but not by the state (excess income).

They enter $10,000 on line 1 of the second Schedule NJ-COJ. This is the excess income taxed only by the city.
The entry on line 9 is the lesser of the amount on line 8 (the proportional credit limitation amount for $10,000)
or the amount from box 9a (the tax actually paid to the city on $10,000).

They calculate the tax paid to the city on $10,000 as follows: $135 × ($10,000 ÷ $30,000) = $45.

                  Credit for Income Taxes Paid to Other Jurisdictions  
                               (Wage Income) 
                               Understanding Income Tax 

 Example #10 – Determining line 1, Schedule NJ-COJ when part of New Jersey income 
                  is taxed by the other jurisdiction. 
 A full-year resident taxpayer claims one dependent child besides themselves, and their filing status is head 
 of household. The amount of wages taxed by the other jurisdiction is $12,500, and the income tax paid to 
 the other jurisdiction is $400. They also reported $2,000 in interest, $3,000 in dividends, and $21,000 in capital 
 gains on their New Jersey return. Since the interest, dividends, and capital gains were not derived from a 
 business, trade, or profession carried on in the other jurisdiction, they do not report that income to the other 
 jurisdiction and do not  include that income on line 1, Schedule NJ-COJ. 

 The credit for taxes paid to the other jurisdiction can never exceed the proportion that the out-of-state 
 income bears to the total New Jersey taxable income multiplied by the New Jersey tax. In this example, only 
 32.4675% of their income was subject to the other jurisdiction’s tax.

 Credit for Income Taxes Paid to Other Jurisdictions  
  (Wage Income) 
  Understanding Income Tax 

 Example #11 – Determining the credit when a part-year resident moves to New Jersey 
 during the tax year and continues to work outside New Jersey. 
 A taxpayer lived in Maryland from January 1 through March 31, then moved to New Jersey on April 1. They 
 worked in Maryland for the entire year, where they earned wages of $100,000. The taxpayer must file two 
 returns with Maryland: a resident return for the period from January 1 through March 31, and a nonresident 
 return for the period April 1 to December 31. They also must file a part-year resident return in New Jersey 
 and report their income between April 1 and December 31. Since the income taxed by New Jersey both was 
 earned in, and taxed by, Maryland, they are eligible for a credit for taxes paid to another jurisdiction.

                                              Understanding Income Tax 

  Example #12 – Determining the credit when a part-year resident who lived and worked 
                  in another state moves to New Jersey and changes jobs to a New Jersey 
                  employer. 
  A taxpayer lived and worked in Maryland from January 1 to March 31. Their wages while a Maryland resident 
  were $25,000. They moved to New Jersey on April 1 and began a new job here, earning $75,000 for the rest 
  of the year. They file a New Jersey resident return for the nine-month period of residency here, reporting only 
  the income earned from April 1 to December 31.  

  Because their income earned while a Maryland resident is not taxed by New Jersey, and the income earned 
  while a New Jersey resident is not taxed by Maryland, they cannot claim a credit for taxes paid to other 
  jurisdictions.

  Example #13  –  Determining  the  credit for  income, other  than wages,  earned in 
                       Pennsylvania. 
  A resident taxpayer earned $50,000 in wages from their Pennsylvania employer. They are also a member of a 
  Pennsylvania partnership. Their share of the partnership’s income for the tax year is $30,000. They paid $5,150 
  in property taxes for the year on the residence they own in New Jersey and is eligible for a property tax 
  deduction or credit. 

  The taxpayer’s partnership income is subject to tax by both New Jersey and Pennsylvania. Therefore, they can 
  claim a credit on  their  New Jersey resident return for income tax paid to Pennsylvania on this income. 
  However, under the provisions of the New Jersey/Pennsylvania Reciprocal Personal Income Tax Agreement, 
  their wages are not subject to tax in Pennsylvania and cannot be included on line 1, Schedule NJ-COJ.

the taxes they paid to Philadelphia is only $3 less when taking the property tax deduction than it would be
without the deduction.

                 Credit for Income Taxes Paid to Other Jurisdictions  
                              (Wage Income) 
                              Understanding Income Tax 

 Example #15 – Determining line 1, Schedule NJ-COJ when the other jurisdiction allows 
                  an adjustment to reduce income that is not allowed in New Jersey, and 
                  when the other jurisdiction taxes income that is not taxed by New 
                  Jersey. 
 Two single New Jersey residents work in New York State and each earn wages of $30,000 while contributing 
 $2,000 to an IRA. Taxpayer one also has unemployment income from New York of $4,000. The schedules 
 below illustrate how to determine the amount of income taxed by both jurisdictions, specifically when there 
 is an adjustment to income allowed by the other jurisdiction, an adjustment for income excluded from line 2, 
 Schedule NJ-COJ, and an adjustment for tax paid to the other jurisdiction. 

 The unemployment income of $4,000  taxpayer one  received is  taxed by  New York but not New Jersey. 
 Because they cannot include it on line 2, Schedule NJ-COJ (income taxed by New Jersey), they cannot include 
 it on line 1, Schedule NJ-COJ (income taxed by both New Jersey and New York).

Credit for Income Taxes Paid to Other Jurisdictions
(Wage Income)
Understanding Income Tax

Example #15 – continued

For both taxpayers, the amount reported on line 1, Schedule NJ-COJ, is the same: $28,000. Since the amount
reported in box 9a must be the tax actually paid to New York on $28,000, taxpayer one calculates the amount
as follows: $1,415 × ($28,000 ÷ $32,000) = $1,238.

Neither taxpayer is eligible for a property tax deduction/credit. They will each complete a Schedule NJ-COJ
like this:
