Frequently asked
Is the doc fee capped in Idaho?
No. Idaho does not cap the documentation fee, and dealers commonly charge ~$300–$500 typical. The fee itself is rarely dropped, so negotiate the out-the-door total instead.
How much is sales tax on a used car in Idaho?
6%. 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 Idaho allows it.
Which dealer fees can I refuse in Idaho?
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 Idaho?
Take the agreed vehicle price, add Idaho's tax (6%), title (~$14), and registration, plus a doc fee in line with no cap; ~$300–$500 typical. If the quote is meaningfully above that math, ask the dealer to walk you through every added line.
