Quick Answer
You may need to file tax returns in two states, but you typically won't pay full taxes to both. If you live in New Jersey and work in New York, you'll pay NY tax on work income but get a credit on your NJ return. About 27% of US workers commute across state lines according to Census data.

The general rule for two-state taxation
You typically need to file tax returns in both states if you live in one state and work in another, but you won't pay full taxes to both. The process works through a system of resident and non-resident returns plus tax credits.
Here's how it works:
1. File as a non-resident in your work state - Pay taxes on income earned there
2. File as a resident in your home state - Report all income, including what you earned in the work state
3. Claim a credit - Your home state gives you credit for taxes paid to the work state
Example: Living in New Jersey, working in New York
Let's say you earn $75,000 working in Manhattan but live in New Jersey:
Note: You pay $2,150 more than a NY resident because NJ's rate (3.8%) is higher than NY's rate (4.67%) on this income level, and NJ taxes the full amount after giving credit for NY taxes paid.
States with reciprocity agreements
Some neighboring states have reciprocity agreements that simplify this process. You only pay taxes to your resident state:
Full Reciprocity (pay only resident state):
How the credit system prevents double taxation
Your home state's credit system ensures you're not truly double-taxed:
Credit calculation: Min(Taxes paid to work state, Home state tax on that same income)
Example scenarios:
Special situations that complicate two-state filing
What you should do
1. Check for reciprocity first: If your states have an agreement, you may only need to file in one state
2. Track your work location: Keep records of which days you work in which state
3. Review your W-2: Box 15-20 shows state wages and withholding for each state
4. File non-resident first: Complete your work state return before your home state return
5. Calculate the credit carefully: Use your home state's specific credit calculation method
6. Consider professional help: Multi-state returns are complex and mistakes are costly
Key takeaway: Most two-state workers file returns in both states but avoid true double taxation through credit systems, though they often pay more than single-state residents due to rate differences and administrative complexity.

Key Takeaway: You'll typically file in both states but pay a net amount somewhere between what each state would charge individually, often resulting in $1,000-3,000 more than single-state residents.

Remote work and multi-state complications
As a remote worker, your tax situation can be more complex than traditional commuters. You might need to file in multiple states depending on:
The 'convenience of employer' trap
Six states have rules that can create unexpected tax obligations for remote workers:
Most aggressive: New York taxes remote workers' full income if their employer is NY-based, unless the employer requires remote work for business necessity (not employee convenience).
Example: You live in Florida (no state tax) but work remotely for a NYC company earning $85,000. New York may claim you owe:
Tracking work location for remote workers
Keep detailed records of where you work each day:
Strategic considerations
Key takeaway: Remote workers may face unexpected multi-state filing requirements, especially from convenience-of-employer states, making residency planning crucial for tax optimization.
Key Takeaway: Remote workers can face surprise tax bills from convenience-of-employer states like New York, potentially owing thousands in taxes to states where they don't live.

Individuals who moved between states during the tax year and need to understand part-year resident filing requirements
Part-year resident returns when you move
If you moved between states during the tax year, you'll typically file as a part-year resident in both your old and new states. This creates a unique three-return situation:
1. Old state part-year resident return: Income earned while living there
2. New state part-year resident return: Income earned after moving
3. Possible non-resident return: If you worked in a third state
Example: Moving from Illinois to Texas mid-year
Earning $90,000 annually, moved July 1st:
Illinois part-year return:
Texas part-year return:
Total state tax: $2,250 vs. $4,500 if you stayed in Illinois all year
Establishing residency date
The key is proving when your residency officially changed:
Apportionment vs. allocation methods
States handle part-year income differently:
Avoiding double taxation on moving
Carefully track which income belongs to which residency period:
Key takeaway: Recent movers typically file part-year returns in both states, potentially saving significant taxes by moving from high-tax to low-tax states, but must carefully document residency change dates.
Key Takeaway: Moving between states mid-year requires part-year resident filings in both states, but can result in substantial tax savings when moving to lower-tax jurisdictions.
