Car Sales Tax, Title, and Registration: How They Work

Tax, title, and registration are the government's share of a car purchase. You cannot negotiate them, and the Consumer Financial Protection Bureau says as much. What you can do is estimate them accurately before you shop and check the dealer's figures against your state's own numbers. The rules differ a great deal from state to state, so this guide explains the mechanics and shows you where to look up the specifics.

Sales tax

What rate applies

Most states charge a sales or use tax on vehicle purchases. A few charge none, and some use a differently named tax, such as an excise or title tax, that works similarly. On top of the state rate, counties and cities may add their own.

The rate that applies is generally the one for where you will register the car, which is normally where you live. Buying across a state line does not usually let you pay the other state's lower rate. See buying a car out of state.

What the rate is applied to

This is where states differ most. The taxable amount usually starts with the vehicle's selling price, and then depends on how your state treats each of these:

The trade-in credit

In many states, when you trade in a vehicle, you pay tax only on the difference between the new car's price and the trade-in allowance. Not every state does this, and some limit it.

Two states' official guidance shows the contrast:

• Texas: the Comptroller states that motor vehicle sales tax is 6.25 percent of the sales price, minus any trade-in allowance.
• California: the state tax agency says a dealer must report the total selling price even when a trade-in is accepted. The trade-in allowance is not deducted.

Example only. A $30,000 car, a $10,000 trade-in, and an example 6% rate:

In a state with the credit, trading in this car saves $600 in tax compared with selling it yourself and bringing cash. That belongs in the comparison when you decide whether to sell or trade in. A private sale has to beat the trade-in offer by more than the tax saving to come out ahead.

Who collects it

• Dealer purchase: the dealer normally collects the tax and sends it to the state.
• Private purchase: you typically pay the tax yourself when you title and register the car. States set a deadline. Texas, for example, gives a private-party buyer 30 calendar days from the purchase date.
• Out-of-state dealer: depending on the two states involved, the dealer may collect your home state's tax, or you may pay it when you register. Many states give credit for tax properly paid to another state. Confirm before you sign.

Leases

Lease taxation is its own topic and varies just as much: tax may be charged on each payment, on the amounts due at signing, or on the full price. See how lease payments are calculated.

For each state's rate and trade-in rule in one table, see car sales tax by state, or go straight to your state's page.

Title

The title is the legal document showing who owns the vehicle. It is separate from registration.

• If you pay cash, the title is issued in your name.
• If you finance, the lender is recorded as lienholder. Depending on the state, the lender holds the title, or you hold a title that shows the lien. Many states keep titles electronically. When the loan is paid off, the lien is released.
• If you lease, the leasing company is the owner on the title.

Before you buy any used car, look at the title for brands such as salvage or rebuilt; see title brands. In a private sale, check that the seller's name matches the title and that any lien has been released. See private seller vs. dealer.

Registration

Registration is your permission to drive the car on public roads. It produces your plates and registration card and is renewed periodically.

Registration fees are set by the state, and sometimes by the county. Depending on where you live they may be a flat amount or based on the vehicle's weight, age, value, or type. Some states add fees for electric or hybrid vehicles, and some charge an annual tax based on value, either with registration or as a separate property tax bill.

States commonly require some or all of the following to register:

• Proof of ownership (title or, for a new car, the manufacturer's certificate of origin)
• Proof of insurance
• Identification and proof of address
• An odometer disclosure
• A safety or emissions inspection, in states and areas that require one
• Payment of tax and fees

Temporary tags

When you buy from a dealer, you normally leave with a temporary plate or permit so you can drive while the state processes the paperwork. How long it is valid differs by state.

• Note the expiration date.
• If your permanent plates or registration have not arrived a couple of weeks before it expires, call the dealer. Delays usually trace back to missing paperwork or, on a used car, a title the dealer is still waiting to receive from the previous lender.
• Do not drive on an expired temporary tag. Ask the dealer for an extension if your state allows one.

The steps, by purchase type

Buying from a dealer in your state

1. The dealer calculates tax, title, and registration and puts them on the buyer's order.
2. You sign title and registration applications along with the sale documents.
3. You leave with temporary tags.
4. The dealer submits everything to the state.
5. Plates and registration arrive by mail or at the dealer. The title goes to you or your lender.

Buying from a private seller

1. The seller signs the title over to you; both of you complete the odometer disclosure and a bill of sale.
2. You insure the car.
3. You take the documents to the motor vehicle agency, or file online where allowed, within your state's deadline.
4. You pay tax, title, and registration there.

Buying from a dealer in another state

Ask the dealer, in writing, which state's tax they will collect and who will handle your home-state registration. Then confirm with your own state's motor vehicle agency.

How to estimate before you shop

1. Find your state's official sites. USAGov keeps a directory of every state's motor vehicle agency. For tax, search for your state's department of revenue or taxation plus "motor vehicle sales tax."
2. Look up the tax rate for your address, including local add-ons, and whether your state deducts trade-ins and rebates.
3. Find the fee schedule or calculator for title and registration. Many states publish an online estimator.
4. Put it together. Our out-the-door calculator lets you combine price, tax, and fees. Advertised prices, including those on The Motor Standard, usually exclude all of these.
5. Ask the dealer for an itemized out-the-door quote and compare. See out-the-door price.

Checking the dealer's numbers

• The tax rate matches your registration address
• The taxable amount treats your trade-in and rebates the way your state does
• Title and registration match the state's fee schedule, or are labeled as estimates
• Government fees are listed separately from dealer fees such as the doc fee
• You know how any overestimate will be refunded

Dealers mostly get this right, since they do it every day. Mistakes are more likely on out-of-state deals. For the dealer's own charges, see dealer fees explained.
