This question comes up constantly in every skoolie group I’ve ever spent time in. Someone posts a gorgeous build and within five comments somebody’s asking “What state is this registered in? What is it registered as?” I went deep on this one because where you register your bus affects what you pay every single year, what hoops you jump through, and honestly how much headache you’re signing up for. (See our guide on How Do You Register a Converted School Bus as an RV? for more on this.)
The seven most popular states for skoolie registration are South Dakota, Texas, Florida, Montana, Indiana, Vermont, and Arizona. South Dakota is the overall favorite among full-time nomads because of its one-night residency requirement and low fees. Texas and Florida offer no state income tax and straightforward registration. Montana is the go-to for LLC registration to avoid sales tax. Indiana and Vermont are sleeper picks with low costs and minimal red tape. The best state for you depends on whether you’re full-timing, where you spend most of your time, and how much you want to deal with inspections.
South Dakota (The Nomad Favorite)
I kept seeing South Dakota come up over and over when I was researching this, and at first I thought it was just one of those internet echo chamber things. But no, there’s a real reason why so many full-timers — bus people, van lifers, RVers, all of them — choose South Dakota as their domicile state.
The big draw is how easy it is to establish residency. You literally need to spend one night in the state. One night at a campground, one night at a hotel, whatever. You get a receipt showing you stayed there, you sign up with a mail forwarding service like Americas Mailbox in Box Elder, and that becomes your legal address. That’s it. You’re a South Dakota resident. (See our guide on Do You Need a CDL to Drive a Skoolie? for more on this.)
From there, registration fees are pretty reasonable. For a converted bus registered as an RV or motorhome, you’re looking at around $100 to $250 per year depending on the weight and age of your vehicle. There’s no state income tax, no vehicle inspections for RVs, and the DMV process is about as painless as a DMV process can be. I talked to a guy on a forum who said he walked into the Pennington County office, had his plates in 20 minutes, and was back on the road. Whether that’s typical or he just got lucky, I don’t know, but the fact that stories like that exist tells you something. (See our guide on The Complete Guide to Insuring a Converted School Bus for more on this.)
One thing to know though. South Dakota does charge a 4.5% excise tax when you first title the vehicle in the state. So if your bus is worth $15,000 on paper, you’re paying around $675 upfront. Some people get around this by having a low purchase price on the bill of sale, which, I’m not gonna tell you what to do there.
The mail forwarding services run about $150 to $200 per year, so factor that in. But for a lot of full-timers it’s worth it because you get a real street address for your driver’s license, insurance, voter registration, all of it. And you never have to go back unless you want to. (See our guide on Can You Get Insurance for a Converted School Bus? for more on this.)
Texas (No State Income Tax, Easy Registration)
Texas is the second most popular choice I found, and it makes a lot of sense for people who actually spend time in the southern half of the country. No state income tax is the headline, but the registration process itself is also pretty straightforward.
To register a vehicle in Texas you need a Texas driver’s license, proof of insurance, and the vehicle title. For a converted school bus that’s been re-titled as an RV or motorhome, the annual registration is somewhere in the $50 to $80 range for most buses, which is honestly one of the lowest I found anywhere. There is a state vehicle inspection required, but for RVs it’s basically just a safety check — lights, brakes, windshield, that kind of thing. Nothing about the conversion itself.
I remember reading a thread where someone asked “In which state did you do the re-registration from school bus to RV?” and like half the responses said Texas. Part of that is just because Texas is huge and a lot of people are already there, but the process is genuinely easier than most states. You bring the bus to a county tax assessor’s office, show them your title, pay the fee, walk out with plates.
Now here’s the thing with Texas. You do need a physical address. It doesn’t have to be a house you own, it can be a friend’s place or a UPS mailbox with a real street address. But you can’t use a P.O. box for your driver’s license.
One more thing on Texas. They charge 6.25% sales tax on vehicle purchases, and some counties tack on a bit more. If you’re buying a bus in Texas that adds up. But if you already own the bus and you’re transferring registration from another state, you typically won’t owe sales tax again as long as you can show you paid it where you bought it.
Florida (Sunshine and Simple Rules)
Florida rounds out the big three nomad-friendly states, and honestly the appeal is pretty obvious. No state income tax, no annual vehicle inspection, and the weather means you’re probably already spending time there anyway.
Registration costs in Florida are based on weight. For a converted bus in the motorhome/RV category, you’re looking at about $100 to $400 per year depending on how heavy your rig is. A shorty under 10,000 lbs will be on the lower end, and a full-size 40-footer that’s pushing 20,000+ lbs after the conversion is going to be closer to the higher end. There’s also a $225 new resident fee if you’re registering for the first time, which catches some people off guard.
What I like about Florida is that the state doesn’t require a vehicle inspection for RVs. At all. You just bring your title, your insurance card, and your money to a local tax collector’s office and they hand you a plate. No one’s looking at your conversion, no one’s checking if you have a bathroom or a kitchen. They just want the paperwork and the payment.
Setting up residency is a little more involved than South Dakota but still not hard. You need a Florida driver’s license, which requires two forms of proof of residential address. A lot of full-timers use St. Brendan’s Isle in Green Cove Springs, which is specifically set up for full-time travelers establishing Florida domicile.
Montana (LLC Registration for No Sales Tax)
Alright, this is the one that gets people excited and also the one that generates the most debate. Montana has no sales tax. Zero. None. And because of that, there’s a whole cottage industry built around registering expensive vehicles through Montana LLCs to avoid paying sales tax in your home state.
Here’s how it works. You form an LLC in Montana — costs about $70 to file, or $500 to $1,000 if you use one of the companies that specialize in this. The LLC buys or is gifted the vehicle. You register the vehicle in Montana under the LLC. Because Montana has no sales tax, you pay zero sales tax on the vehicle. Registration fees are based on the age of the vehicle and for older buses run about $100 to $200 per year.
I was fascinated by this when I first started looking into it. You see Montana plates on million-dollar motorhomes all over the country, and now you know why. For a skoolie builder who just put $40,000 into a conversion, avoiding 6-8% sales tax could mean saving $2,400 to $3,200. That’s real money.
But here’s where I need to be straight with you. This is a gray area, and some states are cracking down on it. California, Virginia, and a few others have started going after people who live in their state but register vehicles through Montana LLCs. The argument is that if you’re physically living in California, you owe California registration and sales tax regardless of what LLC owns your vehicle. People have gotten hit with back taxes and penalties.
If you’re genuinely a full-time traveler with no fixed home state, the Montana LLC route is on solid legal ground. Where it gets sketchy is when someone lives in a house in New Jersey and registers their weekend toy through a Montana LLC to dodge Jersey sales tax. Different situation entirely.
Your LLC will need a registered agent in the state, which runs about $100 to $300 per year, and Montana requires liability insurance on any vehicle registered there. So your actual annual cost is registration plus agent fee plus setup costs. Still way less than sales tax in most states though.
Indiana (Low Fees, Minimal Hassle)
Indiana is one of those states that doesn’t show up in the big nomad domicile conversations, but when someone asks “Can someone tell me what it would cost to plate the bus?” and they start listing out state by state comparisons, Indiana always looks good.
Registration fees in Indiana are based on the vehicle’s age and value, and for older buses they’re shockingly cheap. I saw numbers as low as $40 to $80 per year for an older converted bus. The excise tax is calculated on a depreciation schedule, so by the time a 15 or 20 year old school bus comes through, the tax bill is practically nothing.
Indiana does require a VIN inspection for vehicles coming from out of state, but it’s pretty basic. A police officer or BMV employee checks that the VIN on the bus matches the title. That’s it. They’re not inspecting your conversion, they’re not checking your plumbing or electrical. Just making sure the vehicle is what you say it is.
The state also doesn’t have an annual safety inspection for RVs, which is a big deal if you’ve done a DIY conversion and you’re not super confident about whether your build would pass some strict state inspection. You register it, you plate it, and Indiana pretty much leaves you alone after that.
Where Indiana falls short for the full-time nomad crowd is the income tax. Indiana has a flat 3.05% state income tax, which isn’t terrible but it’s not zero like South Dakota, Texas, or Florida. If you’re working remotely and making decent money, that’s worth factoring in. For a lot of people the low registration fees don’t fully offset the income tax. But if you’ve already got ties to Indiana or you’re spending a lot of time in the Midwest, it’s a solid practical choice.
Vermont (Register by Mail, No Inspection)
This one blew my mind when I first heard about it. Vermont lets you register a vehicle by mail without ever setting foot in the state. You don’t need a Vermont driver’s license, you don’t need to be a Vermont resident, you don’t even need to bring the bus there. You fill out the forms, mail them in with a check, and they mail you back a title and registration.
I know what you’re thinking, because I thought the same thing. How is that real? But it is. Vermont allows out-of-state residents to title and register vehicles there. The process is mainly used for vehicles 15 years or older, which covers most school buses people are converting. And this is particularly useful for people who bought a bus without a title or with a janky title situation, because Vermont is one of the few states that will issue a clean title based on a bill of sale alone for older vehicles.
The registration fee is based on the vehicle’s purchase price or NADA value. For a school bus you bought for $3,000 to $5,000, you’re probably looking at $70 to $150 for the registration. There’s also a 6% purchase and use tax based on the vehicle’s value, so keep that in mind.
Here’s how a lot of people use this. They register the bus in Vermont by mail to get a clean title. Then once they have that Vermont title in hand, they transfer the registration to whatever state they actually want to be domiciled in, like South Dakota or Texas. It’s basically a title laundering process, and that sounds sketchier than it actually is. Vermont designed the system this way on purpose. They’re happy to take your registration fees.
No vehicle inspection required either. So if you’ve got a bus that might not pass inspection in your home state, Vermont is a way to get it legally titled and registered without anyone looking under the hood. (See our guide on Can You Legally Live in a Converted School Bus? for more on this.)
The downside is that registration needs to be renewed annually, and if you’re using it as a stepping stone to another state, that’s an extra step and fee. But for people stuck in title limbo — and there are a LOT of people who buy buses at auction with no title or a title that’s a mess — Vermont is a lifesaver.
What to Consider When Choosing Your State
After digging through all of this, here’s what it really comes down to. The “best” state depends on your specific situation, and anyone who tells you there’s one universal answer is oversimplifying.
If you’re full-timing with no fixed address, South Dakota is probably your best bet. The one-night residency thing is hard to beat, the fees are reasonable, and the mail forwarding infrastructure is already built for people like you. Texas and Florida are strong alternatives, especially if you’re already spending winters in the south.
If you’re trying to avoid sales tax on an expensive build or purchase, Montana’s LLC route is worth looking into. Just make sure you’re actually a full-time traveler and not trying to dodge your home state’s tax obligations from a house in the suburbs.
If you have a title problem, start with Vermont. Get the clean title, then transfer to your preferred domicile state.
And if you just want cheap plates and no one bothering you about inspections, Indiana is hard to beat on pure cost.
One more thing I learned that’s worth mentioning. Whatever state you register in, that’s typically where you need to carry insurance. Make sure you can get a good policy through that state before you commit to domiciling there.
And honestly, talk to other bus people who are registered in the state you’re considering. The DMV website will tell you the rules, but the person who actually went through the process last month will tell you what really happened. That kind of information is worth more than anything I can write here.
So that’s where I landed after all my research. South Dakota for the nomads, Montana for the tax avoiders, Vermont for the title-challenged, and Texas or Florida for people who want simplicity and sunshine. Pick the one that matches how you actually live, not just the one with the lowest sticker price, and you’ll be in good shape.
