How to Establish Domicile — Step by Step

— the real process for the Big Three no-income-tax states, in order —

• • • • •

🌴 Florida 30-day DL deadline

Get a Florida street address — not a PO Box. Full-timers typically use a domicile/mail-forwarding service (Escapees Mail Service in Bushnell, St. Brendan's Isle, or a paid domicile service). This address goes on everything else below.
File a Declaration of Domicile at your county clerk's office (Florida Statutes §222.17) — a notarized sworn statement that Florida is your permanent home. Not legally required, but it's the fastest dated proof of intent and strengthens your case if your old state challenges you. Filing fee is typically under $25.
Get a Florida driver's license within 30 days of establishing residency (Florida Statutes §322.031) — in person, bring proof of identity (passport or birth certificate), proof of SSN, and 2 items of mail/documents showing your FL address. Surrender your old license. ~$48.
Register your vehicle(s) within 10 days — title transfer or VIN verification at the county tax collector, plus proof of Florida auto insurance from a Florida-licensed agent.
Register to vote — can usually be done at the same DMV visit.
If you own FL property: file for homestead exemption with the county property appraiser by March 1.
Sever ties with your old state — cancel the old driver's license/voter registration, update banks/credit cards/insurance/IRS address, and file a final or part-year resident tax return there if applicable.

🤠 Texas 30-day physical presence

Get a Texas mailing address through a mail-forwarding service — Escapees Mail Service in Livingston is the classic option since the town is built around it (there's also Texas Home Base). PO Boxes aren't accepted for DL purposes.
Establish local professional ties in your domicile county — this means actually becoming a patient/client of a doctor, dentist, and insurance agent based in that county (Livingston has ones used to working with Escapees members), not just picking names off a list. The idea is to build a real paper trail of local relationships: schedule an actual checkup or intake appointment so there's a dated record of you as their patient/client, and consider a local bank account too. Escapees calls this one of their "Ten Commandments" of Texas domicile — it's not a form you file, but if your old state (or the IRS) ever questions whether Texas is really your home, "I have a Texas doctor and dentist I actually see" is much stronger evidence than an address alone. It doesn't need to happen on day one, but plan to knock it out within your first few visits to town.
Get your vehicle safety-inspected and Texas-insured. Some counties also require an emissions test — Polk County (Livingston) does not.
Register your vehicle(s) at the county tax office — bring your inspection certificate, insurance, and title. Must be done within 30 days of establishing residency.
Get a Texas driver's license — Texas DPS requires you to show two documents proving you've been physically present in Texas for at least 30 days before they'll issue it (this is an actual hard rule, not just a suggestion). Surrender your old license in person.
Register to vote with the documents from the steps above.
Sign an Affidavit of Domicile before a notary (Escapees keeps this on hand at their Livingston office) and file it with the district clerk.
Sever ties with your old state — sell/rent out any property you kept there, cancel local memberships, update your address everywhere.

🦬 South Dakota 1-night stay + new voting caveat

Sign up with an SD-based mail forwarding service — America's Mailbox and Dakota Post are the two most nomad-specific. They'll give you a Personal Mailbox (PMB) address and a "receipt proving mail service agreement" that the DMV requires.
Get a piece of mail sent to your new address — it doesn't have to be an official document. A magazine, a subscription renewal, a letter you mail to yourself, anything addressed to your name at the SD address works. The only real rules are it has to be printed/typed (handwritten mail isn't accepted) and less than a year old by the time you show it at the DMV.
Book one night at an SD hotel, motel, or campground and keep the receipt — it must show your name and the SD address, and can't be handwritten.
Go to the SD DMV in person (Rapid City is the most nomad-trafficked location) with: your mail service agreement receipt, the one-night stay receipt, your old driver's license to surrender, proof of SSN (card, W-2, or 1099), and proof of citizenship (passport or certified birth certificate — no photocopies).
Sign the Residency Affidavit in front of DMV staff — they're notaries, so this happens on the spot. It's a sworn statement under penalty of perjury that SD is your domicile.
Register your vehicle(s) — in Pennington County this can often be done without needing the driver's license first.
Register to vote — heads up, this is the part that changed. A 2025 law (referred to as HB 1208 in nomad forums) now requires 30 consecutive days in a single SD dwelling to vote in state and local SD elections. If you're using a PMB and can't meet that, you may only be able to vote in federal elections as an overseas-style voter.
Renew your driver's license every 5 years — requires a fresh one-night SD stay receipt (less than a year old), which can often be mailed in rather than requiring an in-person visit.

Where This Info Came From

How I researched this This is compiled from web searches across a few types of sources: (1) Escapees RV Club's own domicile pages — they're a real nonprofit RV club running physical domicile-support offices in Livingston TX, Bushnell FL, and helping with SD, so this is closer to practitioner-level info; (2) South Dakota-specific mail forwarders America's Mailbox and Dakota Post, who publish detailed DMV checklists because it's their core business; (3) a domicile-service company (YourTaxBase) that cites specific statute numbers — Florida Statutes §222.17 and §322.031, South Dakota Codified Laws Title 32 and §12-1-4; and (4) the Texas Department of Public Safety's own site for the 30-day physical presence rule. I did not pull directly from the statute text itself — I'm trusting these secondary sources' citations, so it's worth double-checking anything high-stakes directly against the state's own DMV/tax site or a professional.

Not legal or tax advice. Domicile rules are fact-specific, change often (SD's voting rules just did in 2025), and vary further by county. Confirm current requirements directly with each state's DMV/Secretary of State, and talk to a CPA or tax attorney before making the switch — especially if you're leaving a high-tax state like CA or NY, which audit departing residents aggressively.
