Valim’s CPAs prepare multi-state tax returns for remote workers and people who moved.

You pay tax to the state you live in, if it has an income tax, on pay for work you do from home. Your employer’s state generally cannot tax pay for work you do outside it. The main exception is the convenience of the employer rule, used by New York, Delaware and Pennsylvania. If your office is in one of them, days you choose to work from home can be taxed there too. Connecticut and New Jersey apply a similar rule, but only to workers who live in a state that has its own.

Yes, California keeps taxing income earned in California even after you leave the state. That includes pay for work you did in California and gains on California real estate. For RSUs that vest after you move, the Franchise Tax Board taxes the share earned by California workdays from grant to vest. Gains on stock you sell as a nonresident, and qualified pension or IRA income, are generally not taxed there.

Usually yes, if both states have an income tax, because each expects a return for your months as a resident. Each state taxes all your income from those months, plus any income from that state for the rest of the year. If both tax the same income, the state you lived in then usually gives a credit for the other’s tax. Moving to Texas, which has no income tax, leaves only the return for the state you left.

TurboTax, like any tax software, is only as accurate as your answers about where you lived and worked. For RSUs and stock options, you also need your workdays in each state over the years they were earned. A CPA is worth hiring when you worked in several states in one year or your equity vested across a move. At Valim, a licensed CPA counts your workdays in each state and prepares every state return.

No, because 183 days is only part of a residency test in states such as New York and Massachusetts. Under 183 days, you can still owe tax on your pay for the days you worked in that state. If the state is still your domicile, you are generally a resident there whatever your day count. California has no 183-day test, so fewer days there do not by themselves make you a nonresident.

Living in a state with no income tax, such as Florida, can lower your tax bill. Your old state can still tax income from its sources, such as rent or gains from property you own there. Washington taxes no wages, though its capital gains tax reaches long-term gains above a yearly deduction. A 9.9% tax on income over $1 million, as Washington defines it, is set to start there in 2028. Voters may repeal that tax on November 3, 2026, and a court could still strike it down.

Yes, two states can each tax you as a resident in the same year. It happens when your domicile is in one state and another treats you as a statutory resident. In New York, that takes a permanent place of abode, a home you keep there, for substantially all of the year. It also takes more than 183 days in the state. A state’s credit usually covers only income earned in the other state, so dividends and stock gains can be taxed twice.
