Moving to a Lower Tax State: Hidden Costs to Consider First

State income taxes are often a key driver in changing domicile,

Relocating to a state with no income tax can look like an easy way to trim your tax bill, but the full picture of moving to a lower tax state usually involves more than one line item. States that skip income taxes tend to make up the difference elsewhere, through property taxes, sales taxes, or fees you might not expect.

Changing Your Domicile Means More Than a New Zip Code

Packing boxes and forwarding your mail isn't what actually changes your tax situation. What matters legally is your domicile, the state considered your permanent legal home. Domicile decides where you owe income tax, and it also affects things like eligibility for unemployment benefits or disability coverage.

Katie Carlson, head of wealth strategy at Bank of America Private Bank, points out that a person can hold multiple residences but only one domicile at a time. There's no single test that proves you've switched. Instead, states look at a pattern of behavior and documentation to decide where you truly live.

183 Days and a Long Checklist

Carlson lays out a fairly specific set of steps for anyone trying to formally establish a new domicile. Renting or buying a home in the new state and actually living there is the starting point. From there, she recommends spending as much time as possible in the new location while staying out of the old state for 183 days, since that threshold often matters for residency rules.

Beyond the calendar, she suggests building real ties to the new place: finding local doctors, joining a religious congregation, or getting involved with charitable organizations there. Practical paperwork counts too. That means getting a new driver's license, registering to vote, updating car registrations, and revising your estate plan so it lines up with the new state's laws. Some states also want a formal declaration of domicile filed.
