Frequently asked
Is the doc fee capped in Washington?
Yes. Washington limits the documentation fee by law: capped at $200. A doc fee above the cap on your contract is a compliance problem — point it out and ask for it to be corrected.
How much is sales tax on a used car in Washington?
6.5% state + local + 0.3% motor vehicle tax. Tax is a government charge, not dealer profit — but check that it is calculated on the correct price, with any trade-in credit applied where Washington allows it.
Which dealer fees can I refuse in Washington?
Government charges (sales tax, title, registration) are fixed. Everything else — doc fee, dealer prep, VIN etching, paint protection, nitrogen tires, appearance packages — is dealer profit. You may not get individual lines removed, but you can negotiate the out-the-door total down to offset them, or walk away.
What is a fair out-the-door price in Washington?
Take the agreed vehicle price, add Washington's tax (6.5% state + local + 0.3% motor vehicle tax), title (~$15), and registration, plus a doc fee in line with capped at $200. If the quote is meaningfully above that math, ask the dealer to walk you through every added line.
