At 68 She’ll Sell the House, Buy an RV and Live on the Road. The State on Her Driver’s License Will Still Decide Her Taxes
Selling the house and hitting the road sounds like freedom, but one legal address still follows her everywhere. Her pick controls her taxes, her Medicare costs, and whether her old state keeps sending auditors after her.

She hands the buyer the house keys at closing, climbs into the RV, and notices something strange. She no longer has a home address. At 68, she’s sold the house, bought the rig, and plans to see the country one campground at a time.
Cashing out a house this way is common among retirees. A 2023 Vanguard study cited by The Wall Street Journal found that about 60% of retirees who move after retiring head somewhere more affordable, typically freeing up around $100,000 in home equity. She still keeps a legal home on the road, though. Some state still claims her, and that choice will cost or save her more over the years than the RV itself.
One Legal Home State Runs Her Taxes, Will and Health Plan
Everyone has exactly one domicile. New York’s tax department describes it as the place you intend as your permanent home and plan to return to after being away, and says, “You can only have one domicile.”
That one state decides who taxes her income, where her will gets probated, where the RV is registered, where she votes, and often which health plans she can buy. Driving off without picking one on purpose is how full-timers end up in trouble.
Why Full-Timers Keep Choosing South Dakota, Texas and Florida
All three are among the nine states with no state income tax in 2026. RVers usually name them as the states that let travelers claim residency in a way most others won’t, using a mail-forwarding address.
South Dakota asks the least. For full-time travelers, its licensing process requires a residency affidavit, a receipt showing one night at a South Dakota hotel, campground, or RV park within the past year, and a personal mailbox from a forwarding service. Licenses are generally valid for five years. We’ve covered retiring to South Dakota before, and the case is even simpler for someone who never has a house there.
Texas and Florida follow a similar playbook: an address, a driver’s license, vehicle registration, and voter registration. Florida law also treats a formal declaration of domicile filed in county public records as evidence of intent to stay. Registration fees and RV insurance rates depend on the state, and insurers often price by address too. Get quotes in each state before she commits.
My pick: for a solo full-timer with no family drawing her to Texas or Florida, South Dakota is the simplest choice. If she plans to spend winters in one of the other two, go with that one.
Her Old State May Refuse to Let Go
High-tax states don’t let residents go easily. New York says your 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 biggest source of new Florida taxpayers, at 43187 returns in the 2022-2023 IRS data.
These are the ties to cut:
- License and registration. Turn in the old driver’s license and register the RV in the new state. State tax auditors treat the address on your license and car registration as a sign of where you really live.
- Voter registration. Register in the new state and cancel the old one.
- Any home kept available. A rented apartment or a room at a relative’s that she controls can count as a permanent home.
- Financial addresses. Update banks, brokerage accounts, IRAs, Social Security, and tax returns.
- Local roots. Clubs, doctors, and storage units left in the old state all help an auditor argue she never really left.
Original Medicare Travels and Advantage Plans Often Don’t
Original Medicare covers care in all 50 states from providers who accept Medicare. Some Medicare Advantage plans limit coverage to a defined service area, which gets awkward when she’s three states from home. For most full-timers, Original Medicare plus a Medigap supplement is the better setup.
Medigap has no networks, but premiums are priced by state, so her domicile sets the price. Moving doesn’t give her a guaranteed right to switch plans later without health questions. Part B alone runs $202.90 a month in 2026, and single taxpayers with income over $109,000 pay surcharges. Those income-based surcharges are one of several Medicare traps that catch retirees off guard, and we detailed the rest in a free guide to Medicare’s hidden bills.
What Happens to Her Home-Sale Profit
She can exclude up to $250,000 of gain if she owned the house and lived in it for 2 of the five years before the sale ($500,000 for married couples filing jointly). Any profit above that gets taxed, and her old state will want its share since she lived there when she sold. A big gain also increases her income for the year, which matters for those Medicare surcharges.
On the road, fuel, campground fees, RV insurance, and repairs replace property tax, utilities, and homeowners insurance. Life on the road can cost about as much as life in a house. The Journal found that for some movers, total spending remains almost the same, or even rises.
Pick Her New Home State Before Closing Day
Her first decision comes before anything else: which state becomes home. Then set up the mailbox, license, registration, and voter card in the same short stretch. She should avoid keeping the old license or an extra apartment “just in case.” Hanging on like that is exactly what lets a high-tax state keep taxing her.
