Montana LLC vs South Dakota, Texas and Florida for Vehicle Registration

For someone who does not live in any of the four, Montana is the only one that lets a company formed by mail own and register a vehicle with no sales tax, no inspection and, for most vehicles, no renewal.

South Dakota is a residency decision for full-timers. Texas and Florida register vehicles to their own residents and businesses and collect sales tax at purchase. Montana charges a yearly agent fee the others do not, and its plates draw attention in strict states. Both sides are in the table.

For someone who does not live in any of them, Montana is the only one of the four states that lets a company you form by mail own and register a vehicle with no sales tax, no inspection and, for most vehicles, no renewal. South Dakota, Texas and Florida each come up in the same conversation, usually because a forum post mentioned them. Each has something real going for it, and each asks something of you that Montana does not. This is the honest comparison, with the numbers we can stand behind and a plain “we don’t quote that” where we can’t.

The four, side by side

The tax figures for Texas and Florida are the state motor vehicle rates we use in our savings calculator, checked against the Texas Comptroller and the Florida Department of Revenue in 2026. South Dakota has a different kind of tax on vehicles that we have not verified to the same standard, so we leave the number out rather than guess.

South Dakota: the full-timer’s state

South Dakota’s reputation comes from people who live on the road. The state makes it easy to establish residency with a mail-forwarding address, and full-time RV owners use it for a driver’s license, voter registration and, yes, vehicle registration, with no state income tax. That is a decision about where you live, not about one vehicle. If you are not planning to make South Dakota your legal home, the vehicle registration does not come on its own.

Montana asks nothing about where you live. A Montana LLC is the owner, and the LLC lives at its registered office. You keep your license, your voter registration and your tax home where they are. The non-resident guide walks through it.

Texas: big state, same rules for everyone

Texas charges 6.25% on a vehicle purchase with no local add-on, which is lower than many states, and it dropped its statewide safety inspection in 2025, keeping emissions testing in the large metro counties. For a Texas resident, registering in Texas is straightforward. For a non-resident, there is no path: Texas registers vehicles to people and businesses located in Texas, and the registration renews every year.

Texas does come up for RVs because of its own full-timer community, and the same point applies as South Dakota: it is a residency decision.

Florida: no inspection, but the tax and the renewal

Florida has no safety or emissions inspection, which is the reason people mention it. It charges 6% state sales tax on a vehicle, registrations renew annually, and it registers vehicles to Florida residents and Florida businesses. Bloomberg Tax notes Florida has a six-month rule for residents buying out of state, which matters if you are a Florida resident thinking about Montana: a car delivered and kept outside Florida for six months is treated differently from one that comes straight home.

Where Montana loses

We should say this plainly, because the comparison is not one-sided.

Montana costs something every year. The LLC needs a registered agent, which with us is $99.99 a year. A resident of a no-tax state registering in their own name pays no such fee.

A newer car is not permanent in Montana until it is eleven years old, so until then it renews with the county each year like anywhere else.

Montana plates draw attention in some states. Utah and California now look for them specifically. If the car will be a daily driver in a state with active enforcement, Montana does not make the home-state question go away, and the legality guide says so at length.

Where Montana wins

No sales tax on any vehicle at any price. No inspection, ever. Permanent registration for motorcycles, trailers and most of the cars our clients bring us. A company, not your name, on the public record. And a process that runs by mail from any state, in about a week, without changing where you live.

For a collector car in storage, a vehicle that moves between homes, a boat, a bike, an off-road machine, or an RV that is on the road most of the year, that list is why people choose Montana over the other three. For a daily driver in a strict state, read the legality guide first and then decide.

Questions people ask when comparing states

Those states register vehicles to businesses located there, and a business located there is taxed there, with Texas and Florida collecting sales tax on the purchase. The structure that makes Montana work, a company in a state with no sales tax and no residency test for the company’s members, is Montana’s.

On a car worth more than a few thousand dollars, Montana, because the sales tax the other three charge is larger than our fees. On a very cheap vehicle in a state you already live in, your own state.

If you want a new legal domicile with a license and voting, South Dakota is built for that. If you want to keep your current domicile and register the rig without sales tax, Montana. Some people do both. Our RV page covers the Montana side.

Yes. Montana has no general sales tax on any purchase, and boats and trailers register permanently.
