Out-the-door price in Wyoming
How Wyoming works
- Wyoming charges a 4% state sales tax on a car, plus the county's option taxes where you live, not where the dealer is. The county total runs from 4% to 7% (Park and Sublette 4%, Teton 7%), and 9% inside the Teton Village and Grand Targhee resort districts. This uses the Department of Revenue's chart effective October 1, 2026.
- You do not pay the sales tax to the dealer. Your county treasurer collects it when you first register the car, and the dealer sends your title paperwork to your county clerk. You have 65 days from the purchase to pay. The tax is in the calculator's total because you pay it either way.
- Your trade-in reduces the taxable amount, on new and used cars. The trade has to be titled in your name. A manufacturer's rebate also reduces it when it is applied at the sale and assigned to the dealer, but a rebate you receive by mail afterwards does not. A dealer's own discount reduces it too.
- The doc fee is taxed, and so are freight, dealer preparation and accessories the dealer installs. An extended warranty or service contract is not taxed when it is listed as its own line on the contract.
- Registration is by value: 3% of 60% of the car's MSRP in the first year, so about $720 on a $40,000 new car, plus a $30 state fee and the $15 title fee. The county fee on an older car falls to as little as 0.45% of its original MSRP. Enter the MSRP; without it the calculator uses the price you pay, which understates the fee on a used car.
- Wyoming does not cap the doc fee, and the FTC expects it to be in the advertised price. Ask for the out-the-door price in writing.
- A dealer can issue a 60-day temporary permit so you can drive while you register. You register at your county treasurer's office, not at the dealer.

What a Wyoming advertised price has to include
Wyoming has no rule that says what a dealer's advertised price may leave out, and no cap on the doc fee. Its consumer protection law makes false or misleading statements about a price, and bait-and-switch advertising, unlawful. The FTC expects every fee the dealer requires, the doc fee included, to be in the advertised price, so only government charges like sales tax, title and registration can be added on top. That still isn't your out-the-door number; the calculator above adds the rest for your ZIP.
Federal law comes first
The FTC requires a dealer's advertised price to include every fee the dealer charges. Only charges the government requires you to pay, like tax, title and registration, can be left out. Where a state's rules let a dealer leave a fee out, the dealer still has to follow the federal rule, so the fee goes in. The FTC says a state's doc-fee rules can add disclosures, but they don't change the price that has to be advertised. Read the FTC's guidance.
Has to be in the advertised price
- The doc fee, whatever the dealer calls it (Wyoming has no cap)
- Freight (destination) and dealer preparation charges
- Dealer-installed accessories and anything else the dealer has added to the car
- A title or registration service fee, if the dealer charges one and makes it mandatory
Can still be added on top
- Sales tax: 4% state plus your county's option taxes, paid to your county treasurer
- The $15 title fee, the county registration fee and the $30 state registration fee, an electric car's or plug-in hybrid's decal, and a lien filing fee if you finance
- Optional products you choose to buy, such as a service contract or GAP coverage
- No cap, no set wording: Wyoming has no statute or rule on doc fee amounts or on how a dealer must disclose one. The fee is negotiable, and it is taxed.
- Misleading prices: it is an unlawful deceptive practice to knowingly make false or misleading statements about the price of merchandise or about a price reduction, to advertise merchandise with no intent to sell it as advertised, or to use bait-and-switch advertising, including undisclosed tie-in sales or conditions (W.S. 40-12-105(a)(vii), (x), (xiv)). The Attorney General enforces it. A licensed dealer may not knowingly publish a misleading advertisement (W.S. 31-16-108(a)(i)).
- Rebates: an advertised price has to be what any buyer can pay, whether or not the buyer negotiates, so it can't rely on a rebate or discount only some buyers get (FTC FAQ Q9).
- Registering: the dealer can issue a temporary permit good for 60 days. You register the car, and pay the tax, at your county treasurer's office.

Wyoming OTD questions, answered
Does a trade-in reduce sales tax in Wyoming?
Yes — Wyoming taxes the difference: your trade-in's value is subtracted before tax is computed.
Are manufacturer rebates taxed in Wyoming?
No — rebates passed to you are treated like a cash discount and reduce the taxable amount.
Is the doc fee capped in Wyoming?
No — doc fees are uncapped in Wyoming; buyers report a typical $459.00. It's negotiable as part of your total OTD.
What does a Wyoming dealer's advertised price have to include?
Every fee the dealer requires, including the doc fee and freight (the FTC's position; Wyoming has no rule on what an ad may leave out). Only sales tax, title, registration and other government charges can be added on top.
Is there a cap on doc fees in Wyoming?
No. Wyoming sets no dollar cap and no required wording, so the fee is negotiable. It is taxed at your county's rate because it is part of the sale price.
Do I pay sales tax to the dealer in Wyoming?
No. Your county treasurer collects it when you first register the car, at the rate in the county where you live. You have 65 days from the purchase to pay.
Does a manufacturer rebate lower my Wyoming sales tax?
Yes, when it is applied at the sale and assigned to the dealer. A rebate you take by mail afterwards is taxed. Your trade-in lowers the taxable amount too.
