Overview
Then come the car tabs. The registration itself is the famous "$30" - but a weight fee ($35–$96), a $12.50 filing fee, a $29 office service fee, your city's Transportation Benefit District fee (Seattle: $50), and - inside the Sound Transit district covering urban King, Pierce, and Snohomish counties - the RTA excise tax at 1.1% of a generously calculated MSRP value all pile on. That RTA line alone runs $300–$500 a year on newer vehicles, which is why Seattle-area tab renewals routinely clear $500.
Enter your purchase below and the calculator itemizes every line the licensing office will charge, using the 2026 rates. One warning for private-party buyers: Washington taxes the vehicle's fair market value, not necessarily the price you negotiated - more on that in the FAQs.

Washington tax, title & license FAQ
How much is tax, title and license on a $30,000 car in Seattle?
Roughly $3,865 in year one: about $3,315 in sales tax (≈11.05% with the 0.5% vehicle add-on), $56.50 in title, filing and service fees, $82.75 in base tabs and weight fee, Seattle's $50 TBD fee, and an RTA excise line that depends on the vehicle's MSRP and age - about $360 for a three-year-old car with a $37,000 sticker.
Why is Washington's vehicle tax higher than the regular sales tax?
Cars carry a dedicated add-on: on top of your combined state-plus-local rate, every motor vehicle sale or use owes an extra 0.5% (RCW 82.08.020) earmarked for transportation. It was 0.3% for two decades and rose to 0.5% on January 1, 2026 - so Seattle's 10.55% retail rate becomes about 11.05% at the car dealer.
What is the RTA tax on my car tabs?
Inside the Sound Transit district - the urban parts of King, Pierce, and Snohomish counties - tabs include a 1.1% motor vehicle excise tax funding light rail. It's charged on the vehicle's MSRP run through a 1996-era depreciation schedule that says a 3-year-old car is still worth 89% of sticker, which is why the bill feels inflated compared with what your car would actually sell for.
Does a trade-in reduce Washington sales tax?
Yes. Trade-in value accepted by a dealer is excluded from the taxable selling price, so trading a $12,000 car against a $30,000 purchase in Tacoma (≈10.9% on vehicles) taxes only $18,000 - saving you about $1,308. Private-party sales have no equivalent, since there's no dealer taking a trade.
I found a great private-party deal - will I be taxed on my low price?
Maybe not. Washington calculates use tax on average fair market value (from an industry valuation database), not automatically on your price. Your price is accepted only when the vehicle's value is under $7,500 or your price is within 20% of book value. Pay $6,000 for a car the system values at $12,000 and you'll be taxed on $12,000 unless you document why - a dealer appraisal or condition evidence can rebut it.
What's the new luxury vehicle tax?
Starting January 1, 2026, Washington adds 8% on the portion of a vehicle's selling price above $100,000 (the threshold creeps up 2% each July). A $130,000 truck owes $2,400 in luxury tax on top of the regular ~$14,000+ of sales tax in a Seattle-rate location. It applies to leases too.
Are dealer doc fees part of TTL in Washington?
No - the documentary service fee is the dealer's own charge, capped at $200 in Washington, and it's negotiable in the sense that you can push back on the deal. It's also taxable, so a $200 doc fee in Seattle quietly adds about $22 of tax.
