Quick Answer
A state tax credit for taxes paid to another state prevents double taxation when you owe income tax to multiple states. Most states offer a credit equal to the lesser of: taxes paid to the other state or your home state's tax on that same income, typically reducing your total state tax burden by $500-2,000 annually for cross-border workers.

People who work in one state but live in another, facing potential double taxation
What is a state tax credit for taxes paid to another state?
A state tax credit for taxes paid to another state is a mechanism that prevents you from being taxed twice on the same income when you owe taxes to multiple states. According to the Multistate Tax Commission, over 15 million Americans work across state lines and potentially face this double taxation issue.
The credit typically equals the lesser of two amounts: the taxes you actually paid to the other state, or the amount of tax your home state would impose on that same income. This ensures you never pay more in total state taxes than you would if all your income was earned in your highest-tax state.
Example: New Jersey resident working in New York
Let's say you live in New Jersey but work in New York City, earning $80,000 annually. Here's how the credit works:
New York taxes (as nonresident):
New Jersey taxes (as resident):
Total state tax burden: $5,500 (just the NY taxes)
Without the credit, you'd pay $5,500 to NY plus $2,800 to NJ = $8,300 total.
How the credit calculation works
The credit is calculated using this formula:
Credit = Lesser of:
1. Taxes paid to other state
2. (Home state tax rate × Income earned in other state)
Key factors that determine your credit
What you should do
1. File as a nonresident in the work state first to establish the tax paid
2. File as a resident in your home state and claim the credit on the designated form (often called "Credit for Taxes Paid to Another State")
3. Keep documentation of all taxes paid to other states
4. Use our paycheck calculator to estimate your multi-state tax burden throughout the year

Key takeaway: State tax credits typically save cross-border workers $500-2,000 annually by preventing double taxation, with the credit limited to the lesser of taxes paid to the other state or your home state's tax on that income.

Key Takeaway: State tax credits prevent double taxation by crediting taxes paid to other states against your home state liability, typically saving $500-2,000 annually for cross-border workers.
Common multi-state tax scenarios and credit calculations
| Scenario | Other State Tax | Home State Tax | Credit Amount | Total Burden |
|---|---|---|---|---|
| Work in higher-tax state | $3,200 | $2,400 | $2,400 | $3,200 |
| Work in lower-tax state | $1,800 | $2,400 | $1,800 | $2,400 |
| Work in no-tax state | $0 | $2,400 | $0 | $2,400 |

Remote workers who may work from different states throughout the year or for companies in different states
How state tax credits work for remote workers
As a remote worker, your state tax credit situation depends on where your employer is located, where you physically work, and your state of residence. The key distinction is between "convenience of employer" states and "physical presence" states.
Convenience of employer states (like New York, Connecticut, Delaware) tax you based on where your employer is located, even if you work remotely from another state. Physical presence states only tax income for work actually performed within their borders.
Example: Remote worker scenario
You live in Florida (no state income tax) but work remotely for a New York company, earning $90,000:
But if you lived in Pennsylvania instead:
Special considerations for remote workers
Key takeaway: Remote workers often face complex multi-state tax situations where credits become essential, especially when working for companies in "convenience of employer" states that tax remote work income.
Key Takeaway: Remote workers in "convenience of employer" states often need tax credits to avoid double taxation, particularly when the employer state has higher rates than the residence state.

Individuals who changed states during the tax year and need to file part-year resident returns in multiple states
State tax credits when you move during the year
When you move between states during the tax year, you'll typically file part-year resident returns in both states. Each state taxes the income earned while you were a resident, but you may still qualify for credits to prevent double taxation on certain types of income.
Example: Mid-year move from Texas to California
You moved from Texas to California on July 1, earning $70,000 total for the year:
Texas portion (January-June): $35,000
California portion (July-December): $35,000
But here's where it gets tricky: if you had investment income, retirement distributions, or other non-wage income, California might try to tax the full-year amounts. This is where you'd need to claim credits or file for apportionment.
Common moving scenarios requiring credits
What to do when you move
1. File part-year returns in both states
2. Track your move date precisely - it determines income allocation
3. Keep documentation of when income was earned vs. received
4. Consider estimated payments if moving to a higher-tax state mid-year
Key takeaway: People who move mid-year often need state tax credits for income that gets double-taxed, particularly investment income and deferred compensation that spans the move date.
Key Takeaway: Mid-year movers may need state tax credits for investment income and deferred compensation that gets taxed by both the old and new residence states.
