Your Tax Life Doesn’t Move With the Boxes
Relocating to a new state is exciting — new scenery, new opportunities, maybe even a lower cost of living. But while you’re busy forwarding your mail and figuring out where to buy groceries, your taxes are quietly becoming a lot more complicated. Moving across state lines can affect everything from how much you owe to which states get to tax your income. Getting ahead of this early saves real headaches later.
Establishing Your New Domicile
The first thing both states will look at is where you’re actually domiciled — meaning where you intend to make your permanent home. This isn’t just about where you sleep most nights. States look at concrete actions to determine residency, and if you’re not careful, two states might try to tax the same income.
To firmly establish domicile in your new state, move quickly on the practical steps:
- Get a new driver’s license and register your vehicle in the new state
- Update your voter registration
- Open a local bank account and update your address with financial institutions
- Transfer your primary physician, dentist, and other regular services
- Update your address on legal documents like your will or trust
The sooner you do these things, the cleaner your paper trail — and the harder it is for your old state to claim you’re still a resident.
Part-Year Resident Filing: What It Actually Means
In the year you move, you’ll almost certainly need to file as a part-year resident in both states. This means each state taxes only the income you earned while living there. Say you moved from Illinois to Texas in July — you’d file a part-year return in Illinois for the income earned between January and July, and Texas has no state income tax at all, so you’d owe nothing there.
The math sounds simple, but it gets messy with things like bonuses, stock vesting, rental income, or freelance work that doesn’t fit neatly into a calendar. If your employer paid out a year-end bonus in December but you moved in August, your old state may still want a piece of it depending on how the income is sourced.
Remote Workers Have Extra Layers to Manage
If you work remotely for a company based in your old state, some states have what’s known as a “convenience of the employer” rule. New York is the most well-known example — it taxes remote employees on income earned for New York-based employers, even if those employees never set foot in the state. Before assuming your move eliminates your old state tax bill, check whether your employer’s home state has a similar policy.
States With No Income Tax: A Real Advantage
Moving from a high-tax state like California or New York to one with no state income tax — Florida, Nevada, Washington, or Texas, for example — can mean significant savings. But California in particular is aggressive about auditing former residents. If you spend more than a certain number of days in California after claiming you’ve moved, the state may argue you’re still a resident and tax your income accordingly. Keep a travel log if you visit often.
A Few More Things to Keep on Your Radar
Beyond income tax, a move can affect other financial areas worth reviewing:
- Property tax: Rates vary wildly by state and even by county. Factor this into your housing budget early.
- Estate and inheritance taxes: Some states have them; many don’t. If you have a will or estate plan, review it after your move.
- 529 college savings plans: Some states only offer deductions for contributions to their own in-state plan. Moving may affect your strategy.
Work With a Tax Professional Who Knows Multi-State Rules
Multi-state tax returns are one of the more complex situations a tax preparer handles. A good CPA or enrolled agent who has experience with relocation cases can catch things most people miss — like a credit your new state offers for taxes paid to another state, which can prevent double taxation on the same income.
Moving is a fresh start in a lot of ways. Taking a few hours to sort out the tax side of things means you can actually enjoy that fresh start without an unexpected bill showing up the following April.
