Overview
Miss the window and Idaho applies a flat $20 late-filing penalty - no monthly escalation, no ballooning cap like some states use. It's a one-time hit whether you're a week late or a year late, which makes the math easy: budget $34 instead of $14 if you know you're not going to make the deadline.

Pay the $14 title fee plus your county's filing add-on, along with any sales tax and registration due at the same visit.

Idaho title transfer FAQ
How much does it cost to transfer a title in Idaho?
$14 statutory plus your county's filing add-on (typically a few dollars, up to about $19 in the pricier counties), so roughly $16–$33 total. On top of that, budget for 6% sales tax and registration, since the county collects everything in one visit.
What happens if I'm late transferring a title?
A flat $20 penalty, regardless of whether you're one week or one year overdue. Idaho doesn't compound this monthly the way some states escalate title penalties, which makes a late transfer relatively predictable.
Can I transfer a title online in Idaho?
No - title transfers require an in-person visit to your county assessor's motor vehicle desk with the signed title, a bill of sale, and ID. Registration renewals can often be done online, but a new-owner title transfer cannot.
Do all Idaho vehicles need a title?
Nearly all cars, trucks, and motorcycles do. Some older or smaller boats are the exception - Idaho only requires boat titles for 2000-model-year-or-newer vessels with permanent propulsion (inboards, sterndrives, PWCs, sailboats) or any outboard-powered boat over 12 feet.
What if I lost the title and need a duplicate?
Apply for a duplicate at your county assessor for the same $14 base fee plus your county's add-on. You'll need to show ID and, if there's a lienholder, their release or consent.
Do I need a title if the vehicle is a genuine gift?
Yes - the title still has to transfer within 30 days, you just don't pay sales tax on it if you file Form ST-133GT with the county. The $14 title fee (plus county add-on) is still due.
