Taxes When You Move to a New State

Moving to a new state doesn't just change your address — it can substantially change your income tax bill, particularly if you're moving between states with very different tax regimes. Planning the timing and execution of your move carefully can make a meaningful difference.

In the year you move, you're generally treated as a part-year resident of both your old state and your new state. Most states require you to file a part-year resident return and pay tax on all income earned while you were a resident of that state, plus income derived from in-state sources (like rental income from property or business income earned there) even after you leave. You may need to file two state returns for the year of the move. Some states are more aggressive than others about defining who is still a resident — keeping clear records of your move date and your actual location throughout the year is important.

High-income taxpayers moving from high-tax states like California, New York, or New Jersey to low- or no-income-tax states like Texas, Florida, Tennessee, or Nevada can save substantial amounts in state taxes. But states like California and New York are known for aggressively auditing people who claim to have changed their domicile, particularly if the taxpayer has retained ties to the original state. To establish a new domicile, you generally need to: change your voter registration, update your driver's license, register your cars in the new state, update your legal documents (wills, trusts), spend more than half your time in the new state, and sever as many ties to the old state as possible. Simply buying a home in another state while retaining your California or New York residency isn't enough — both states look for a clear "intent to permanently reside" in the new location.

Timing income and deductions around a state move can be tax-efficient. If you're moving from a high-tax state to a no-tax state, you generally want to defer income into the years when you're living in the new state and accelerate deductions into the years when you're in the high-tax state. For example, if you have significant capital gains to realize or a large bonus coming, timing it after the move can avoid high state taxes. Conversely, if you have deductible expenses or losses, realizing them before the move lets you use them against income that would otherwise be subject to high state rates.

Remote workers who move to a new state while keeping their job at a company based in their old state need to understand their state's "convenience of the employer" rule. States like New York tax nonresidents who work remotely from another state on income that could have been earned at the New York office, unless the remote work was required by the employer — not just convenient for the employee. This can create situations where a New Yorker who moves to Florida still owes New York income tax on their remote work income. Understanding your specific employer's state of business operations is critical before assuming a state move eliminates your old state tax exposure.
