Overview
Buying a bike triggers the usual pair alongside registration: a $14 title fee (plus county add-on) and 6% sales tax on the price, with the same private-sale rules as cars - no book-value floor, but no trade-in credit outside a dealer purchase either. None of that changes based on engine size or the rider's age; Idaho treats a 250cc commuter bike and a full touring cruiser identically for registration purposes.

Common questions
Idaho motorcycle fees FAQ
- How much is motorcycle registration in Idaho per year?
- $29.25–$40.25 all-in: the flat $25 registration ($19 base + $6 safety fee), $4.25 in EMS/State Police fees, and a $3–$14 county add-on. Unlike cars, the base fee never changes with the bike's age.
- Why don't motorcycles get the age-based discount cars do?
- Idaho Code sets a flat rate for motorcycles and mopeds rather than the stepped 1–2/3–6/7+ year schedule used for cars and light trucks. A brand-new sport bike and a 20-year-old cruiser pay the identical $25 base fee.
- What's the $6 'motorcycle safety program fee' for?
- It funds Idaho STAR, the state's motorcycle rider training and safety course program, and is baked into every motorcycle registration - you can't opt out of it even if you never take a course.
- Do motorcycles pay the same sales tax as cars?
- Yes - 6% of the price, with a dealer trade-in credit but none on private sales, and the same family/gift exemption via Form ST-133 or ST-133GT if you're receiving the bike from a qualifying relative.
- Is there an emissions test for motorcycles in Idaho?
- No - Idaho has no emissions testing requirement for any vehicle type anywhere in the state as of mid-2023, motorcycles included.
- Do scooters and mopeds register at the same rate as motorcycles?
- Yes, if they're street-legal and require a title - same $25 flat fee. Very small mopeds and e-bikes that fall under Idaho's low-power exemptions may not need registration at all; check with your county assessor if you're unsure which category yours falls into.
