Free Idaho Motorcycle Bill of Sale
The office that appraises Idaho farmland also titles Idaho motorcycles: vehicle transfers run through the COUNTY ASSESSOR'S motor vehicle counter, not a central ITD or DMV branch — the detail that sends half of new-to-Idaho buyers to the wrong building. The rest is pleasantly flat: a 6% sales tax with zero local additions anywhere in the state, the ITD 3738 bill of sale to document the deal, a 30-day titling window, and no inspection of any kind for motorcycles — no safety check, no emissions, nothing between paperwork and pavement.

Idaho Motorcycle Bill of Sale — What You Need to Know
Sales Tax Details
Same flat 6% Idaho sales tax on motorcycle sales.
Idaho Motorcycle Sale — Step-by-Step Checklist
- Verify the frame VIN against the Idaho title before paying.
- Complete form ITD 3738 (Idaho's bill of sale) with VIN, year, make, model, odometer, price, date, and both signatures.
- Seller signs the title over with the odometer disclosure.
- Buyer files at the COUNTY ASSESSOR'S motor vehicle office — not an ITD or DMV building — within 30 days.
- Buyer pays the flat 6% Idaho sales tax (no city or county adds anything) plus title and registration fees.
- No inspections to schedule — Idaho has no safety or emissions program for motorcycles.
- Buyer: hold Idaho's motorcycle endorsement before riding on public roads.
Common Pitfalls
- Driving to an ITD office — the Idaho Transportation Department issues the forms, but the county assessor's counter processes the transfer.
- Expecting local tax variation — Idaho's 6% is genuinely flat statewide; any different quote is a mistake.
- Missing the 30-day window — Idaho's late-title penalties apply to bikes like everything else.
- Declaring a token price on ITD 3738 — the assessor's office appraises things for a living and questions numbers far from market.
Pro Tip
