Do I Have to File Taxes in Two States?

Yes, you often have to file taxes in two states if you lived in one state and earned income in another, moved between states during the year, or work remotely for an out-of-state employer. Your resident state taxes all of your income, the other state taxes only the income sourced there, and your resident state gives you a credit for taxes paid to the other state so you are not taxed twice on the same dollars. Reciprocity agreements between some neighboring states remove the second filing for commuters. Filing in two states rarely means paying double; it means splitting the tax between them.

When do you have to file taxes in two states?

Filing a second state return is common, and it comes down to where you lived and where the income was earned. These are the situations that create a two-state filing:

The one thing these share is that your resident state taxes all of your income, from every source, while a nonresident state taxes only the income you earned inside its borders.

How the credit for taxes paid to another state works

Being taxed by two states on the same income sounds like double taxation, and states solve it with a credit. You generally file the nonresident return first, calculate the tax that state charges on the income earned there, then claim that amount as a credit on your resident return. The credit is usually limited to what your home state would have charged on the same income.

The practical effect: you end up paying roughly the higher of the two states' rates on the shared income, not the sum of both. If you live in a low-tax state and work in a high-tax one, your home-state credit may not fully cover the other state's tax, so you feel the higher rate. If you live in the higher-tax state, the credit typically wipes out the double hit.

Reciprocity agreements: the exception for commuters

Some neighboring states have reciprocity agreements that let you pay tax only to your home state on wages, even when you work across the border. If your states have a reciprocity agreement, you file a form with your employer so they withhold your home state's tax, and you skip the nonresident return entirely.

There are around 30 such agreements across 16 states and the District of Columbia. Pennsylvania and New Jersey have one, so a New Jersey resident working in Philadelphia is taxed only by New Jersey on those wages. Reciprocity covers wages, not self-employment or business income, and not every neighboring pair has an agreement, so check before you assume. The full reciprocity map is on our state tax filing guide.

Remote work and the convenience of the employer rule

Remote work is where two-state filing gets tricky. As a default, remote employees are taxed by the state where they physically do the work, which is usually where they live. But a handful of states apply a convenience of the employer rule: if you work remotely for an employer based in that state for your own convenience rather than the employer's necessity, that state can still tax your wages. New York is the best-known example, and a few others follow similar rules.

If you live in one state and work remotely for an employer in a convenience-rule state, you can end up owing tax to both, with your home state's credit softening the overlap. This is the single most misunderstood area of multi-state taxation, and it is worth confirming your specific states before you file.

Moving states during the year

If you moved during 2025, you were a resident of each state for part of the year, so you file a part-year resident return in both. Each state taxes the income you earned while you lived there, and you allocate income and deductions by the portion of the year in each place. Keep dated records of your move, since the date determines which state taxes which paycheck. High-tax states scrutinize moves to no-income-tax states closely, so documentation matters.

Which states make this easier

Eight states have no individual income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Wyoming, and New Hampshire. If you live or earn in one of them, that side of the equation disappears, though you may still owe your other state. States with income tax vary enormously in rates and rules, from California's graduated brackets up to 12.3% to Pennsylvania's flat 3.07%, so the two-state math depends heavily on the specific pair. Our per-state guides, including California, New York, and Virginia, cover each state's forms, deadlines, and rates.

Frequently asked questions

Do I have to file taxes in two states?

Yes, if you lived in one state and earned income in another, moved between states during the year, or in some remote-work cases. Your resident state taxes all your income and the other state taxes the income earned there. A credit on your resident return for taxes paid to the other state prevents you from being taxed twice on the same dollars.

Do I pay double taxes if I work in a different state than I live?

Almost never. You file a nonresident return in the state where you work and a resident return where you live, then claim a credit on your resident return for the tax paid to the work state. The credit offsets the overlap, so you effectively pay the higher of the two states' rates on the shared income, not both rates added together.

How do taxes work if you work remotely in another state?

By default, you are taxed by the state where you physically work, usually your home state. The exception is the convenience of the employer rule in states like New York, which can tax a remote worker whose employer is based there. When both states tax the income, your resident state's credit for taxes paid elsewhere reduces the double hit.

Do I have to file state taxes if I moved to another state?

Usually yes. If you moved during the year you file a part-year resident return in each state, and each taxes the income you earned while living there. Keep records of your move date, because it decides which state taxes each paycheck. If one of the states has no income tax, you only file in the other.
