At 68, She Plans to Sell Her Home, Buy an RV, and Live on the Road. Her Driver’s License State Will Still Shape Her Taxes

Turning a house into cash and heading out in an RV may feel like total freedom, but one legal home still determines a lot. That state affects her taxes, her Medicare costs, and whether her former state continues to question her residency.

She hands over the house keys at closing, climbs into the RV, and realizes she no longer has a street address. At 68, she has sold the house, bought the rig, and is preparing to travel from campground to campground.

For many retirees, selling a home this way is a familiar move. A 2023 Vanguard study cited by The Wall Street Journal found that about 60% of retirees who relocate after leaving work move to a less expensive area, often unlocking roughly $100,000 in home equity. Even so, a full-time traveler still needs a legal home base. One state will claim her as a resident, and that decision can affect her finances more than the RV itself.

One State of Residence Determines Taxes, Estate Issues, and Health Coverage

Everyone has only one domicile. New York’s tax department defines it as the place a person intends to keep as a permanent home and to which they plan to return after being away, and says, “You can only have one domicile.”

That state decides which government taxes her income, where her will is handled, where the RV is registered, where she votes, and often which health plans she can buy. Leaving without making a clear choice is how many full-timers run into trouble.

Why Many Full-Time RVers Choose South Dakota, Texas, or Florida

Those three are among the nine states with no state income tax in 2026. RV travelers often point to them as places that make residency easier to establish through a mail-forwarding address.

South Dakota is often the easiest option. For full-time travelers, the state’s licensing process calls for a residency affidavit, proof of one overnight stay at a South Dakota hotel, campground, or RV park within the past year, and a personal mailbox from a forwarding service. Licenses are generally good for five years. Retiring to South Dakota has been covered before, and the process is even more straightforward for someone who never maintained a house there.

Texas and Florida use a similar approach: an address, a driver’s license, vehicle registration, and voter registration. Florida law also recognizes a formal declaration of domicile filed in county public records as evidence of intent to remain. Registration fees and RV insurance costs vary by state, and insurers often set rates based on address as well. She should compare quotes before making a final choice.

For a solo full-timer with no family connection pulling her toward Texas or Florida, South Dakota may be the simplest choice. If she expects to spend winters in one of the other two, that state may make more sense.

Her Former State May Not Let Her Leave Easily

High-tax states can be reluctant to release former residents. New York says a person’s domicile “does not change until you can demonstrate that you have abandoned your New York domicile and established a new domicile outside New York State.” It can also tax someone who keeps a year-round home there and spends 184 days or more in the state. New York was also the largest source of new Florida taxpayers, with 43,187 returns in the 2022-2023 IRS data.

These are the ties she should cut:

1. License and registration. Give up the old driver’s license and register the RV in the new state. Tax auditors often view the license and vehicle registration address as evidence of where someone actually lives.
2. Voter registration. Register in the new state and cancel the old registration.
3. Any home kept available. A rented apartment or a room at a relative’s place that she controls can still count as a permanent home.
4. Financial records. Update banks, brokerage accounts, IRAs, Social Security, and tax returns.
5. Local connections. Clubs, doctors, and storage units left behind can give an auditor an argument that she never truly moved.

Original Medicare Travels, But Many Medicare Advantage Plans Do Not

Original Medicare covers care in all 50 states from providers who accept Medicare. Some Medicare Advantage plans limit coverage to a specific service area, which can become inconvenient when she is far from home. For most full-time travelers, Original Medicare with a Medigap supplement is the better fit.

Medigap has no networks, but premiums are set by state, so her domicile determines the price. Moving does not guarantee an automatic right to change plans later without health questions. Part B alone costs $202.90 a month in 2026, and single taxpayers with income above $109,000 pay surcharges. Those income-based surcharges are one of several Medicare surprises that catch retirees off guard, and the rest were detailed in a free guide to Medicare’s hidden bills.

What Happens to the Profit From Selling the House

She can exclude up to $250,000 of gain if she owned and lived in the home for two of the five years before the sale ($500,000 for married couples filing jointly). Any gain above that is taxable, and the state where she lived at the time of sale will want its share. A large profit can also raise her income for the year, which matters for Medicare surcharges.

Once she is on the road, fuel, campground fees, RV insurance, and repairs replace property tax, utilities, and homeowners insurance. Life in an RV can cost about as much as living in a house. The Journal found that for some movers, total spending remains almost the same, or even rises.

Choose the New Home State Before the Sale Closes

Her first decision should come before anything else: select the state that will serve as her home. After that, she should set up the mailbox, license, registration, and voter card in a short span of time. She should not keep the old license or hold onto an extra apartment “just in case.” That kind of tie is exactly what allows a high-tax state to keep taxing her.
