Out-of-State Vehicle Purchase - Title, Tax, and Transport
Buying a car in another state is perfectly legal and can get you a better deal or a specific vehicle you cannot find locally. The paperwork, however, involves two states instead of one, and getting it wrong can delay your registration by months.
What does your home state require?
Registration deadline, odometer rules, and whether your state wants a notarized bill of sale all depend on where you register. Pick your state to see them, then get a bill of sale built for it.
What the seller needs to do
The seller's obligations are the same as any private sale: sign the title over to you correctly (including any co-owner), complete the odometer disclosure, and provide a bill of sale. In some states the seller must also notify their DMV of the sale within a few days to stop liability for future tickets or accidents involving the vehicle.
Make sure the title is signed exactly as the seller's name appears on it. A middle initial omitted or a suffix like "Jr." left off can cause rejections at your home DMV.
Getting home legally - transport options
Once the plates come off, you have three options:
- Transit or trip permit. Some states issue these through the DMV. Check your home state and the seller's state to see which (if either) issues transit permits to private buyers.
- Transport on a trailer or flatbed. If no transit permit is available, this is your fallback. Renting a trailer or hiring a transport service avoids the plate problem entirely.
- Dealer involvement (for transport permit only). A small number of buyers work through a dealer even on a private purchase just to obtain a temporary tag. This adds cost but solves the transport problem.
Sales tax and where you pay it
Buying in a state with no sales tax (Oregon, Montana, New Hampshire, Delaware, Alaska) does not mean you avoid tax if you live in a tax state. Your home state will collect its sales tax when you register the vehicle. Most states give a credit for any tax already paid to the selling state, so you pay the difference rather than the full amount twice.
The bill of sale is your evidence of the purchase price, which is what the tax is calculated on. Keep it accurate.
Why a Vehicle POA often matters here
Out-of-state sales frequently involve one party who cannot appear at a DMV in person. A Vehicle Power of Attorney allows the buyer to complete the title transfer without requiring the seller to travel. It also lets a third party (spouse, attorney, trusted agent) handle DMV paperwork on behalf of either party.
If there is any chance you will not be able to get both parties physically together for the DMV trip, get the POA signed at the time of sale while everyone is present.

Titling in your home state - what to bring
Every state differs slightly, but you will generally need:
- The original signed title (not a photocopy)
- The bill of sale showing sale price and date
- Odometer disclosure (required for vehicles under 20 model years old)
- Proof of insurance in your name
- Government-issued photo ID
- Payment for title fee, registration fee, and sales tax
Some states also require a VIN inspection, an emissions test, or a safety inspection before they will issue new plates. Call your DMV ahead of time.
Out-of-state vehicle purchase checklist
Print this and keep it with you. Two states are involved, so a single missed step can stall your registration for weeks.
At the sale, while you are both present
- Confirm the seller signs the title exactly as their name appears on it
- Get all co-owner signatures on the title
- Complete the odometer disclosure (required under 20 model years old)
- Get a signed bill of sale showing the true sale price and date
- Have the seller sign a Vehicle POA if you cannot both reach the DMV together
- Confirm whether the seller must notify their DMV of the sale
Getting the car home legally
- Do not drive on the seller's plates, they leave with the seller
- Check whether your state or the seller's state issues a transit permit
- If no permit is available, arrange a trailer or transport service
At your home state DMV
- Bring the original signed title, not a photocopy
- Bring the bill of sale, proof of insurance, and photo ID
- Bring payment for title, registration, and sales tax
- Ask whether a VIN inspection, emissions, or safety test is required first
- File before your state's title-transfer deadline to avoid penalties
General guidance, not legal advice. Deadlines, tax credits, and inspection rules are set by your home state.
Common mistakes to avoid
- Signing the bill of sale with the wrong state's form (use one that matches where you will register, or use a neutral form)
- Failing to get all co-owner signatures on the title
- Driving home on expired or seller's plates
- Missing your state's title transfer deadline
- Not getting a notarized bill of sale when your home state requires one
