State Taxes for International Students: Why Federal Status Is Not Enough
Find out when an international student may need a state income tax return and what to check after moving or working in a state.
Filing a federal return does not settle your state tax obligations. States have their own rules for residency, source income, filing thresholds, credits, and deadlines. Your federal nonresident tax status is only one part of the picture.
Look at where income was earned
A state where you worked may tax wages earned there, even if you lived in another state. A state where you lived may also ask you to file based on its residency rules. On a W-2, boxes 15 through 20 can show state wage and withholding information, but those boxes alone do not decide every filing requirement.
Scholarships, fellowships, remote work, and multi-state employment can complicate sourcing. Keep dates, addresses, employer locations, and pay records for each state.
Federal and state residency can differ
A student may be a nonresident for federal income tax while a state applies a different residency test. Some states have no individual income tax; others have separate nonresident and part-year forms. Do not copy the federal residency answer onto a state return without checking that state’s instructions.
If you moved during the year, review both states. A credit for tax paid to another state may be available in some situations, but the rules depend on the state and income category.
Use the tax year’s state guidance
Find the tax agency website for each relevant state and read its instructions for the exact year you are filing. Check whether an extension applies separately from the federal extension and whether a local tax return is also required. Save all state filing confirmations with your federal return.
What to do next
Make a list of states where you lived or earned income, then apply each state’s own filing instructions.
