Credit for Taxes Paid to Another State: Complete Guide

When two states tax the same income, your resident state usually lets you claim a state tax credit for taxes paid to the other state. The credit is a dollar-for-dollar reduction in your resident state tax bill, capped at what your resident state would have charged on the overlapping income. This prevents double taxation in most situations.

So you're filing your taxes after a cross-state move, and you notice something odd. Your old state is asking for tax on income you earned there. Your new state is also asking for tax on that same income because you're a resident now. Or maybe you worked in one state while living in another all year, and both want their cut.

You may start to wonder, "am I really supposed to pay tax twice on the same dollars?" The short answer is: usually no.

Most states offer a credit to reduce your bill when the same income gets taxed twice, which typically limits what you owe to roughly what one state would have charged.

However, not every situation qualifies, and rules vary by state. Here's how it works.

What Is a State Tax Credit?

State tax credit for taxes paid: A dollar-for-dollar reduction in your resident state's tax bill that offsets income taxes you already paid to another state, up to a cap.

When two states tax the same income, your resident state calculates what you owe based on all your taxable income for the year. Then it lets you claim a credit to reduce that bill, based on taxes paid to the other state. Your resident state tax liability goes down, sometimes significantly.

The credit generally prevents you from paying full tax to both states on overlapping income, though some limitations apply.

How to claim the credit for taxes paid to another state:

1. File your nonresident or part-year return first in the state where you earned income but don't currently reside. Calculate your actual tax liability there.

2. File your resident state return and report all income from every source for the year.

3. Complete your resident state's credit form (often called "Credit for Taxes Paid to Another State". the exact form name varies by state).

4. Enter your actual tax liability from the other state. not the amount withheld from paychecks, but what you actually owe after filing.

5. Apply the credit cap. Your credit is the lesser of: (a) your actual tax paid to the other state, or (b) what your resident state would have charged on that same income.

6. Verify your combined tax burden. After the credit, your total state tax on the overlapping income should roughly equal what one state would have charged.

When the Credit Applies

You typically need this credit when:

• You work remotely for an out-of-state employer that withholds in its state
• You own rental property in a state different from your residence
• You're a multi-state business owner with income sourced to multiple states
• You're a part-year resident of both states and some income is sourced to each

Example: You live in New Jersey but work for a New York employer (pre-move). NY taxes the wages as NY-sourced income. NJ also taxes the wages as your resident state. You file a NY nonresident return, then claim a credit on your NJ return for the NY tax paid.

The table above shows when the credit applies at a glance. Below is a closer look at how some situations play out in real life.

Scenario 1. You Were a Resident of Two States During the Year

If you moved mid-year, you were a part-year resident in your old state and a part-year resident in your new state. In most cases, each state taxes only the income earned while you lived there, so there is no true double taxation.

The credit becomes relevant only if the same income is taxed by both states. This can happen with items that do not divide neatly by date, such as a year-end bonus earned over the entire year or certain investment income received during a transition period.

When that overlap occurs, your new resident state typically provides the credit, limited to the overlapping portion.

Scenario 2. You Worked in One State but Lived in Another

If you lived in State A but worked in State B, State B may tax your income because that's where you performed the work. State A also taxes it because you're a resident.

If a reciprocal agreement exists between the two states, only your resident state taxes the income and no credit is needed. Without one, you'll generally file a nonresident income tax return in the work state and a resident return in your home state. Your resident state typically offers a credit for the tax liability you owe the nonresident state.

Scenario 3. You Had Income Sourced to Another State

If you own rental property in State B but you're a resident of State A, State B may tax that rental income even though you don't live there. State A also taxes it because you're a resident. You'll generally claim a credit on your resident state return to offset taxes paid to the state where the property is located.

Business income sourced to another state works similarly. The credit typically prevents double taxation in these situations.

When Credits Don't Apply

The credit only applies when the same income is taxed by two states. If that overlap doesn’t exist, there’s nothing to offset. Common situations where the credit does not apply include:

• Only one state taxed the income. If you earned income in just one state and only that state imposed income tax, there is no double taxation to correct.
• Your resident state does not offer a credit. This is uncommon, but rules vary. Some states limit the types of income eligible for the credit.
• You moved to or from a state with no income tax. If one state does not impose income tax, there is no second tax to credit.
• The income type is not eligible under your state’s rules. Some states restrict credits for certain categories of income or apply special sourcing rules.

How the Credit Is Calculated

Most states use a formula like:

Credit = lesser of:

• Tax actually paid to the other state on the relevant income, OR
• What your home state would have taxed on that same income

Example:

$100,000 of wages taxed by NY at 6.85% = $6,850 NY tax.

NJ would have taxed the same at 6.37% = $6,370.

Credit on NJ return: $6,370 (the smaller amount).

The extra $480 isn't refunded — states don't compensate you for paying more tax to another state than they would have charged.

Reciprocity Agreements

Some neighboring states have reciprocity agreements where residents of one state working in another only pay tax to their home state:

• Arizona ↔ California, Indiana, Oregon, Virginia
• Illinois ↔ Iowa, Kentucky, Michigan, Wisconsin
• Indiana ↔ Kentucky, Michigan, Ohio, Pennsylvania, Wisconsin
• Iowa ↔ Illinois
• Kentucky ↔ IL, IN, MI, OH, VA, WV, WI
• Maryland ↔ DC, PA, VA, WV
• Minnesota ↔ Michigan, North Dakota
• Michigan ↔ IL, IN, KY, MN, OH, WI
• Montana ↔ North Dakota
• New Jersey ↔ Pennsylvania
• North Dakota ↔ Minnesota, Montana
• Ohio ↔ IN, KY, MI, PA, WV
• Pennsylvania ↔ IN, MD, NJ, OH, VA, WV
• Virginia ↔ DC, KY, MD, PA, WV
• West Virginia ↔ KY, MD, OH, PA, VA
• Wisconsin ↔ IL, IN, KY, MI

If reciprocity applies, submit the appropriate exemption form to your employer so only your home state's tax is withheld.

Why This Matters

Beyond taxation of the same income, moving can also change which deductions and credits you qualify for in each state, adding another layer of complexity to multi-state filing. Income gets sourced to different locations depending on where you lived or worked. Without the credit, you'd pay full state tax to both states on the overlapping income, effectively doubling your burden on that portion.

The credit for taxes paid prevents that in most situations. It doesn't eliminate filing in multiple states, but it generally caps your combined state tax liability at roughly what one state would have charged.

Important Limitations

The credit applies to income taxes only. It doesn't cover sales tax, property tax, or other fees. You have to actually owe income tax to another state for the credit to apply. If you moved from a state with no income tax, there's nothing to offset.

The credit is based on your actual tax liability in the other state, not on the amount withheld from your paychecks. The income that qualifies can vary by state.

Tying It All Together

The credit for taxes paid prevents double taxation, but it doesn't eliminate the need to file state returns in more than one state. You'll generally still file a nonresident return or part-year resident return in the other state, then claim the credit when you file your resident state return.

Claiming the credit on your resident return can reduce what you owe significantly. The credit is available to offset tax liability when you face overlapping obligations, though rules vary by state.

If the numbers aren't adding up or you're not sure whether the credit applies, it may be worth talking to a tax pro. They can help ensure you're claiming the credit correctly and not overpaying on your state returns.
