Do I file State returns even if no tax is owed?
Annual return obligations of this kind are generally required on the facts rather than on the tax result, so a nil position does not remove one. Non-residents and foreign residents with income sourced to a US state — wages worked in-state, rental property, or business receipts.
What happens if I have missed State returns for several years?
Missed years are dealt with as a package rather than one at a time, because the route chosen for the first year affects the relief available for the rest. We map the years and the obligations before anything is filed.
Is State returns the same as the other reports I already file?
No. State non-resident income tax returns, which follow their own residency and sourcing rules independent of the federal return and of any treaty. Satisfying a different obligation, even one covering the same accounts or entity, does nothing for this one.
Do I have to file a state return if a treaty exempts me?
Often yes. A treaty is an agreement between national governments and it binds the federal tax system. States set their own income tax rules, and many of them do not conform to treaty articles at all, or conform only to parts of the federal code that do not carry the treaty through. So income the treaty protects from federal tax can still be taxable by the state it was earned in, and the state return is still due. This is the most common surprise in a cross-border employment file, and it usually surfaces when the state writes to the filer directly.
I worked in one state for a few weeks, do I owe tax there?
Possibly. States tax non-residents on income sourced to the state, and for employment income the source is usually where the work was physically performed. Some states begin at the first day worked, others apply a threshold of days or earnings before the filing obligation starts, and those thresholds differ from one state to the next. Because the rules are set state by state, the answer depends on which state you were in and what you did there, not on your federal position or your immigration category. Work out the days by state before assuming there is nothing to file.
My employer withheld state tax for a state I never worked in?
That happens when payroll is set to the office an employee is attached to rather than the place the work was performed. The remedy is usually a non-resident return in the state that received the withholding, showing no income sourced there and claiming the amount back, together with a return in the state where the work was actually done. It is two filings rather than one, and they have to agree with each other. Correcting the payroll set-up for the following year matters as much as recovering the tax for the year that has gone.
Does one state give credit for tax paid to another state?
Resident states generally relieve double taxation on the same income by crediting tax paid to the state where it was sourced, but the mechanics differ and the credit usually flows in one direction only, from the state of residence to the source state. For a non-resident filer with no state of residence in the United States there is no resident return to carry the credit, so the source state’s tax is simply a cost. Whether it can then be relieved on a home-country return is a separate question that turns on that country’s own rules.
I rent out a US property but live abroad, which state return?
The state the property sits in. Rental income is sourced where the real estate is, so the filing obligation follows the property rather than the owner, and it exists whatever your immigration status or country of residence. That state’s rules decide how the rent is computed, which expenses are allowed, and whether payments to an out-of-state owner attract withholding of their own. A sale of the property brings the same state back into the picture for the gain. Treat the state return as part of holding US property, not as an optional extra to the federal one.
Can a state tax me when I am not a US resident at all?
Yes. State taxing power runs on the state’s own connection to the income and to the person, and it does not depend on federal residence status or on a visa category. A foreign resident with wages earned in a state, a rental property there, or business receipts sourced to it can be a non-resident taxpayer of that state while being a non-resident alien federally. The two systems ask different questions and are answered separately. The practical consequence is that the state filings have to be identified from the facts, not read off the federal return.
Does a nonresident alien have to file a state return as well as a federal one?
Often, yes, and the state answer does not follow the federal one. States are not parties to the tax treaties, so a treaty position that removes federal tax can leave the state tax standing. Each state applies its own sourcing and its own residency test, and several tax a nonresident on income from work performed there from the first day. The federal return settles the treaty; the state returns are decided state by state, on where the work and the property actually were.
How do I know whether I am a covered expatriate?
Three tests, and one is enough. Net worth of $2,000,000 or more on the day you expatriate. Average annual net income tax above an inflation-adjusted figure for the five preceding years — $206,000 for 2025. Or failure to certify on Form 8854 that you complied with all federal tax obligations for those five years. The third catches people the first two never would, which is why compliance history is the thing to fix before, not after. See covered expatriate testing.
