A Practical Guide to Filing a Nonresident State Tax Return in the U.S.
Tax season can be challenging for many nonresidents who come to the United States to work or study. Between federal rules, state rules, and different filing requirements, it’s easy to feel overwhelmed.
While most people focus on their federal tax return, filing state taxes as a nonresident is just as important to ensure your overall tax withholding is correct and that you remain fully compliant with U.S. tax law.
In this guide, we explain what a nonresident state tax return is, when you need to file one, and how to file correctly with J1 Summer Tax Back.
What is a nonresident state tax return?
A nonresident state tax return is a state-level tax filing required when you earn income in a U.S. state where you are not considered a resident for tax purposes.
In many situations, nonresidents must file:
- A federal nonresident tax return, and
- One or more state tax returns, depending on where income was earned
Some states require a nonresident return even if you never lived there but earned income there.
There are eight U.S. states with no state income tax:
- Alaska
- Florida
- Nevada
- South Dakota
- Tennessee
- Texas
- Washington
- Wyoming
If you earned income only in these states, you generally do not need to file a state return there.
Most other states have agreements designed to prevent double taxation, as long as the correct returns are filed.
How is state residency determined?
State residency rules vary widely.
Each state applies its own criteria, which may include:
- Where you lived (domicile)
- How long you stayed in the state
- Your reason for being there
- Your intent to return
In many cases:
- If you lived and worked in a state for most of the year, you may be considered a resident
- If you earned income in a state but never lived there, you are usually a nonresident for that state
Some states closely follow federal residency rules, while others apply stricter or more flexible definitions.
What if you moved states during the tax year?
If you moved from one state to another, you may be classified as a part-year resident.
States evaluate:
- Length of stay
- Purpose of the move
- Whether you intended to establish a permanent home
This can result in:
- A part-year resident return for one state
- A nonresident return for another
Each state handles this differently, so accurate reporting is essential.
Do nonresidents have to file a state tax return?
In most cases, yes, if you earned income in that state.
You usually have a filing requirement if:
- You worked in the state
- State tax was withheld from your paycheck
- You earned taxable income sourced to that state
Each state sets its own income thresholds and rules, so requirements differ.
State tax forms you should know about
Every state has its own tax forms for nonresidents. For example:
- New York nonresidents file Form IT-203
- California nonresidents file Form 540NR
Deadlines, calculations, and deductions vary by state, which makes filing manually especially difficult for nonresidents.
When can you file a nonresident state tax return?
The federal tax deadline for 2026 is April 15 for the 2025 tax year.
Many states align their deadlines with the federal deadline, but some do not. Always check state-specific deadlines to avoid penalties.
State reciprocity agreements explained
Some U.S. states have reciprocity agreements, which allow workers to pay income tax only in their state of residence, even if they work in another state.
If no reciprocity agreement exists:
- Tax is typically withheld where the work was performed
- You may need to file returns in both states to reconcile the tax
Can I file my federal return before my state return?
Yes, and in most cases, you must.
State tax returns often require information from your federal return. If you plan to e-file, your federal return must be prepared first.
Filing state returns before federal filing is generally not recommended.
I filed taxes in the wrong state – what should I do?
This happens more often than you might think.
Each state has its own amended return process (for example, California uses Schedule X). Filing an amended return as soon as possible usually resolves the issue and minimizes penalties.
