When you sell your house, ditch the 9-to-5, and pull out of your driveway for the last time, one question hits you almost immediately: where do I legally live now?
That question is not philosophical. It is deeply practical. Your domicile state determines how much you pay in income tax, what you pay to register your vehicles, how much your insurance costs, and where you vote. For a family chasing FIRE from the road, those decisions compound fast. We spent weeks running the numbers before we ever dropped our first jacks in a campground. Here is everything we learned, and exactly why we chose Florida.
What Domicile Actually Means for Full-Time RVers
Domicile is the state you claim as your permanent legal home, even when you have no fixed address. It is not the same as residency, which can be triggered by spending a certain number of days in a state. Domicile is about intent. You are telling one state: this is where I belong, this is where I pay taxes, this is where I vote.
Every person in the United States has exactly one domicile at all times. You cannot be domiciled nowhere, and you cannot be domiciled in two places. For full-time RVers, that means deliberately choosing a home base state and taking concrete steps to establish it: getting a driver's license, registering vehicles, registering to vote, and using a mailing address there.
The states you pass through may still try to claim you owe them taxes if you earn income within their borders, but your domicile state is the one that governs your overall tax picture, your vehicle registrations, and your legal identity. Pick the wrong one and you could be hemorrhaging money every single year. Pick the right one and you keep thousands of dollars working toward financial independence instead.
The Big Three: Florida vs. Texas vs. South Dakota
Ask any full-timer where to domicile and you will hear the same three states over and over: Florida, Texas, and South Dakota. All three have no state income tax, and all three have built infrastructure to welcome RVers. But the details matter enormously when you are optimizing for FIRE.
| Category | Florida | Texas | South Dakota |
|---|---|---|---|
| State Income Tax | None | None | None |
| Sales Tax | 6.0% (+ local, ~7.0% avg) | 6.25% (+ local, ~8.2% avg) | 4.5% (+ local, ~6.5% avg) |
| Vehicle Registration | $14.50–$32.50 + initial title | $50.75 base + inspection | ~$36–$144/yr by weight |
| Vehicle Inspection | None required | Annual inspection required | None required |
| Insurance Cost | Higher than avg (but manageable) | Above national avg | Below national avg |
| Asset Protection | Strongest in the US Winner | Strong homestead | Good trust laws |
| Mail Forwarding | MyRVMail (Crestview), Escapees, St. Brendan's Isle | Escapees (Livingston), St. Brendan's Isle | Americas Mailbox, Dakota Post |
| Thousand Trails Access | Multiple FL parks Winner | Several TX parks | No parks nearby |
| Our Overall Pick | Best for our family Winner | Great option | Easiest setup |
All three states will save you from state income tax, which is the single biggest line item. But once you move past that headline number, the differences start to add up — especially when you factor in where you actually spend your time.
Why Florida Won for Our Family
When we ran every number side by side and factored in our actual lifestyle, Florida came out ahead for reasons that go beyond just the tax situation.
No State Income Tax + Best Asset Protection in America
This is the table stakes. All three contenders share the no-income-tax advantage, but Florida goes further with the strongest asset protection laws in the country. Florida's homestead exemption protects your primary residence from creditors with no cap on value. For a FIRE family, that kind of legal protection matters as your net worth grows. Florida also has no estate tax and no inheritance tax — your wealth transfers cleanly to the next generation.
We Actually Spend Time There
This is the big one nobody talks about when recommending South Dakota. We spend a significant chunk of every winter in Florida, bouncing between Thousand Trails parks like Orlando and Peace River. Having our domicile in a state where we actually park our trailer strengthens our legal claim enormously. If a state ever challenges your domicile, the strongest defense is showing you have real ties there. South Dakota is great on paper, but we would have been driving through once a year at best.
MyRVMail Made It Easy
We use MyRVMail in Crestview, Florida as our mail forwarding service and they have been fantastic. They give you a real physical street address (not a PO Box), scan your mail so you can view it online, and forward packages wherever you are parked. Their service is built specifically for full-time RVers and they understand the domicile process inside and out. The team there helped walk us through exactly what we needed to bring to the DMV. It felt like having a concierge for the entire domicile switch.
Cheap Vehicle Registration, No Inspections
Florida registration fees are among the lowest in the country. There is no annual vehicle inspection, which is a huge deal when you are never in one place for long. Texas requires yearly inspections, meaning you have to physically be in Texas once a year or find a workaround. With Florida, we register by mail for renewals and never need to make a special trip back for routine paperwork.
Healthcare Marketplace Works for FIRE
Florida uses healthcare.gov for its ACA marketplace, and the plan options are solid. As a FIRE family managing our income carefully for ACA subsidy purposes, Florida's marketplace gives us access to PPO plans with national networks. Since we are often parked far from Florida, having a broad network plan is critical. We have had no issues getting care on the road with our Florida-based plan.
How to Establish Florida Domicile: Step by Step
-
Sign Up with MyRVMail
Before you do anything else, set up your mail forwarding. We went with MyRVMail in Crestview, FL. They give you a physical street address that you will use as your legal address on everything — driver's license, vehicle registration, bank accounts, voter registration. Sign up online, complete the USPS Form 1583 (they walk you through it), and you are ready. Their plans start around $15/month and include mail scanning so you can see everything digitally.
-
Gather Your Documents
Florida requires specific documents for a REAL ID-compliant driver's license. You will need: proof of identity (passport or birth certificate), proof of Social Security number (SSN card or W-2), two proofs of Florida residential address (your MyRVMail welcome letter plus a bank statement or utility bill showing your FL address), and your current out-of-state driver's license. MyRVMail provides a welcome letter specifically formatted for the DMV — they know exactly what Florida requires.
-
Visit a Florida DMV Office
Make an appointment at a Florida DHSMV office (the Crestview office near MyRVMail is popular with full-timers for this reason). Bring all your documents, surrender your old state license, pass the vision test, and pay the fee (around $48). You will walk out with a temporary paper license. Your permanent Florida license arrives by mail at your MyRVMail address within about two weeks. They will scan it and forward it to wherever you are parked.
-
Register Your Vehicles
Head to the county tax collector's office with your vehicle titles (or lien information), your new Florida driver's license, and proof of Florida insurance. Florida charges an initial title transfer fee plus annual registration. For our truck and travel trailer combined, it was very reasonable. No inspection required. If you are financing, your lienholder will need to send the title directly — MyRVMail can receive it and coordinate.
-
Update Your Insurance
Call your insurance company and update your garaging address to your MyRVMail Florida address. Yes, Florida insurance runs higher than South Dakota. But here is the thing — we were already paying for full-timer RV insurance, and the difference was smaller than the internet makes it sound. Shop around and bundle your truck and RV. We found competitive rates that were not dramatically different from what we paid before. The asset protection benefits of Florida domicile more than offset the insurance premium difference.
-
Register to Vote
Register to vote in Florida online at registertovoteflorida.gov or at the county supervisor of elections office while you are in town. This is a critical step for establishing domicile intent. Florida offers vote-by-mail, so you can request a mail ballot for every election and it gets sent to wherever you are. We have voted from campgrounds in three different states without any issues.
-
Update Everything Else
Change your address with the IRS, your banks, credit cards, brokerage accounts, the Social Security Administration, and any professional licenses. Update your Amazon and online shopping accounts. File a change of address with USPS to forward stragglers to your MyRVMail address. This cleanup takes a couple of hours but locks in your domicile across every system. We made a checklist and knocked it out over two evenings at the campground.
Why Not South Dakota?
We know South Dakota is the darling of the full-timer community, and for good reason — the setup process is dead simple (one overnight stay, walk-in DMV, done). If the only thing you care about is the fastest and easiest domicile switch, South Dakota wins hands down.
But here is the reality for our family: we never go to South Dakota. Our Thousand Trails membership has us bouncing around the Southeast and along the coasts. Having a domicile in a state we visit once a year (or less) felt legally flimsy. If a state ever audits your domicile claim, they look at real ties — where do you bank, where do you get your mail, where do you spend time, where do you vote? We have real ties to Florida. We park there for months every winter. Our mail service is physically there. It just made sense.
The insurance cost difference is real but manageable, and Florida's asset protection and our actual travel patterns tipped the scales decisively.
Common Mistakes to Avoid
- Not cutting ties with your old state. If you keep a driver's license, voter registration, or property in your previous state, they may argue you are still domiciled there and owe taxes. Surrender your old license, cancel voter registration, and update every account.
- Spending too many days in a high-tax state. States like California and New York aggressively pursue part-year residency claims. Track your travel days carefully. We use a simple spreadsheet that logs which state we sleep in each night.
- Using a PO Box instead of a physical address. Florida DMV requires a physical street address. MyRVMail gives you one — make sure whatever service you choose does the same.
- Ignoring your mail forwarding renewal. If your Florida mailing address lapses, your domicile argument weakens. Set a calendar reminder and keep it current.
- Skipping voter registration. Voting in your domicile state is one of the strongest signals of intent. Do not skip this step.
This article reflects our personal experience and research as of 2026. It is not tax advice, legal advice, or financial advice. Tax laws, registration requirements, and healthcare marketplace rules change frequently. Consult a qualified tax professional or attorney who understands full-time RV domicile issues before making any decisions. Your situation may differ from ours, and what worked for our family may not be the right choice for yours.
The Bottom Line
Choosing a domicile state is one of the most impactful financial decisions a full-time RV family can make. For us, Florida delivered the best combination of zero income tax, strong asset protection, proximity to our actual travel patterns, and a mail forwarding service (MyRVMail) that made the whole process painless. We spent a couple of days handling the paperwork and walked away with a legal home that makes sense for how we actually live.
South Dakota might be easier to set up. Texas might have cheaper insurance. But Florida is where we park, where we get our mail, and where our domicile claim is strongest. Those savings and protections go straight into our investment accounts, compounding toward the day we hit our FIRE number.
