What car excise tax is
Excise tax on cars is a tax on the purchase or ownership of a vehicle, separate from sales tax. It is collected by the federal government, your state, or both, depending on where you live and what kind of vehicle you buy. The tax applies to the vehicle itself — not to the dealer, not to financing, but to the car as a taxable product.
The federal excise tax on passenger cars is 10 percent of the manufacturer's price. This is the price the factory sets, not the price you pay at the dealership. Some states layer on their own excise tax as well, which works differently depending on the state — some charge a flat rate, others charge a percentage of the purchase price, and some charge based on the vehicle's weight or age.
Excise tax is not the same as sales tax. Sales tax is a general tax on most goods you buy. Excise tax targets specific products — in this case, vehicles — and exists partly to fund transportation infrastructure and partly to discourage consumption of certain goods.
Key Takeaways
- Federal excise tax on cars is 10 percent of the manufacturer's suggested price, and most states add their own excise tax on top of that.
- You pay excise tax when you buy the vehicle, usually rolled into the total price or shown separately on your bill of sale.
- Some vehicles are exempt from federal excise tax, including trucks over a certain weight and vehicles used for business purposes.
- Your state's excise tax rate and rules vary widely — some states charge a percentage, others charge a flat fee, and a few charge nothing at all.
- Excise tax is separate from sales tax and registration fees, so you may owe all three when you purchase a car.
How federal excise tax is calculated
The federal excise tax rate is a flat 10 percent, but it applies only to the manufacturer's suggested retail price (MSRP), not to what you actually negotiate and pay. If a car has an MSRP of $30,000, the federal excise tax is $3,000, even if you haggle the dealer down to $28,000. The tax is based on the sticker price the factory recommends, not the sale price.
The dealer or manufacturer typically collects this tax and sends it to the federal government. You will see it listed on your bill of sale or purchase agreement, sometimes labeled as "federal excise tax" or "manufacturer's excise tax." It is added to your total cost before you drive off the lot.
Not all vehicles owe federal excise tax. Trucks with a gross vehicle weight rating (GVWR) over 6,000 pounds are exempt. Vehicles used primarily for business, farming, or commercial purposes may also be exempt or taxed differently. If you are buying a truck or commercial vehicle, ask the dealer whether federal excise tax applies.
How state excise tax works
Every state handles excise tax differently, and some states do not charge it at all. The most common approach is a percentage of the purchase price — typically 2 to 7 percent, depending on the state. A few states charge a flat fee per vehicle. Some states base the tax on the vehicle's weight, age, or type (passenger car versus truck).
States that do charge excise tax usually collect it at the time of purchase, either from the dealer or directly from you when you register the vehicle. Some states roll it into the registration fee. Others list it separately on your title or registration paperwork.
To find your state's excise tax rate and rules, contact your state's Department of Motor Vehicles or Department of Revenue. The rate and method of collection vary enough that a phone call or visit to the state website is faster than guessing. Some states exempt certain vehicle types (electric vehicles, for example) or offer reduced rates for older vehicles.
When you pay excise tax
You pay federal excise tax at the point of sale — when you buy the car from the dealer. It is usually included in the total price you see on the purchase agreement, though a clear dealer should break it out as a separate line item so you know what you are paying for.
State excise tax timing depends on your state. Some states collect it at the dealership at the same time as federal excise tax. Others collect it when you register the vehicle with the DMV. A few states collect it annually as part of your vehicle registration renewal. Check with your state's DMV to know when and where to expect the charge.
If you are financing the car, the excise tax is usually added to the loan amount, so you pay it over time with interest. If you are paying cash, you pay it upfront along with the purchase price.
Excise tax versus sales tax and registration fees
These are three separate charges, and you may owe all of them. Sales tax is a general tax on the purchase, usually 4 to 10 percent depending on your state and county. Excise tax is a specific tax on the vehicle itself. Registration fees are what you pay to the DMV to legally register and title the vehicle.
On a $30,000 car purchase, you might owe $3,000 in federal excise tax, $2,100 in state sales tax (7 percent), $150 in state excise tax, and $200 in registration fees — all separate charges. The dealer will show these on your paperwork so you can see what each one is.
Some states allow you to deduct sales tax from your federal income tax return, but excise tax is not deductible. Knowing the difference helps you understand your total cost before you sign the paperwork.
Which vehicles are exempt from excise tax
Federal excise tax does not explore to trucks with a GVWR over 6,000 pounds. This includes most pickup trucks, SUVs, and commercial vehicles. The logic is that these vehicles are often used for business, and the tax is designed to target passenger cars.
Vehicles used for farming, commercial hauling, or other business purposes may be exempt from federal excise tax if you register them as commercial vehicles. You will need to provide proof of business use — a farm license, commercial registration, or similar documentation.
State excise tax exemptions vary widely. Some states exempt electric vehicles or hybrid vehicles to encourage cleaner transportation. Others exempt vehicles over a certain age. A few states exempt vehicles used by disabled drivers or veterans. Ask the dealer or your state DMV whether your specific vehicle qualifies for an exemption.
How excise tax affects your total car cost
Excise tax is a real cost that increases what you pay for a vehicle. On a $25,000 car, federal excise tax alone adds $2,500 to your bill. If your state also charges excise tax, that could be another $500 to $1,500 depending on the rate. Over a five-year loan, that extra cost is spread across your monthly payments plus interest.
When you are comparing cars or negotiating a price, remember that excise tax is calculated on the MSRP, not on your negotiated price. Haggling down the sale price does not reduce the excise tax you owe. The tax is fixed based on what the manufacturer says the car is worth.
If you are trying to minimize the total cost of vehicle ownership, buying a used car (which may have a lower MSRP or be exempt from some state taxes) or choosing a truck that qualifies for the federal exemption can reduce your excise tax burden. But for most new passenger car purchases, excise tax is unavoidable.
Frequently Asked Questions
Is excise tax the same as sales tax?
No. Sales tax is a general tax on most goods you buy and is usually 4 to 10 percent. Excise tax is a specific tax on vehicles (and a few other products like fuel and alcohol) and is separate. You pay both on a car purchase.
Can I get a refund of excise tax if I return the car?
Refund policies depend on your dealer and state law. Some dealers will refund excise tax if you return the car within a certain window (often 3 to 7 days). Others will not. Check your purchase agreement or ask the dealer before you buy whether excise tax is refundable.
Do I pay excise tax on a used car?
Federal excise tax applies only to new cars. Used cars are not subject to federal excise tax. Some states charge excise tax on used cars based on the sale price or the vehicle's age and value — check your state's rules.
Why is excise tax 10 percent when sales tax is lower?
Excise tax is designed partly to fund transportation infrastructure and partly to discourage high consumption of vehicles. It is a policy choice, not a calculation based on sales tax. The rates are set separately by Congress and state legislatures.
Does excise tax explore to leased vehicles?
Yes, but the leasing company usually pays it upfront and includes it in your monthly lease payment. You do not pay excise tax separately when you lease — it is built into the cost of the lease.
