What an expired-registration ticket costs in Idaho

Idaho gives no grace period. A registration period runs twelve months and expires at midnight on the last day of the period shown on the registration card (Idaho Code 49-402(1)). The only extension is the ITD director’s power under 49-430(1) to extend the renewal date by up to 45 days for individuals, counties or the whole state for good cause shown, which is not an automatic grace period. The amount is set statewide, not by county, by the Idaho Supreme Court’s Infraction Penalty Schedule under Idaho Infraction Rule 9(b) (effective July 1, 2025, the version the rule links as current in October 2026), but it depends on which section the officer writes on the citation, and no statute, court rule or ITD page we found says which section must be used for a lapsed renewal. Three sections fit. 49-456(1) makes it unlawful to operate, or let someone operate, a vehicle on a highway that is not registered and does not have the plates assigned to it for the current registration year; the schedule lists “Operating vehicle without registration, I.C. § 49-456(1)” at a $44.50 fixed penalty and a $101.00 total, and $101 is the fine ITD’s March 2026 announcement of the sticker change says applies when a vehicle without registration is cited. 49-428 requires plates to be displayed during the current registration year and treats the plates together with the registration card as the plates for the year on the card (until July 1, 2026 it also required the current year’s sticker on each plate); the schedule lists failure to display license plate under 49-428 at a $10.50 fixed penalty and a $67.00 total. 49-430, the duty to renew, makes a violation an infraction (49-430(2)) but has no line of its own on the schedule, so it takes the $15.50 default for infractions without a set penalty (Idaho Code 18-113A(4)) and the schedule’s “other infractions” total of $72. Each total includes the same $56.50 in court costs set by statute and charged on the infraction: a $16.50 general fee (31-3201A(3)), a $15 peace officer standards and training fee (31-3201B), a $10 court technology fee (31-3201(5)), a $5 county administrative surcharge (31-3201(3)) and a $10 infraction surcharge (31-3201H(2)(c)). No court may withhold judgment or suspend any part of the fixed penalty and costs (Infraction Rule 9(d)). Mailing the full total so the court receives it by the appearance date on the citation counts as admitting the charge (Rule 6(a)); that date is 5 to 21 days after the citation (Rule 5(a)). Since July 1, 2026 Idaho no longer issues or requires registration stickers (House Bill 533 of 2026); ITD says owners must still keep the registration current and show registration documents when police ask, and that police verify registration status electronically. Renewing late carries no DMV late fee: none appears in the registration fee table on ITD’s Vehicle Registrations page or anywhere in Title 49, Chapter 4 of the Idaho Code, the registration chapter (both searched in October 2026). The lapsed months are not given back, though: a renewal keeps the vehicle’s original registration month (49-402(1)) and is charged the fee for the established registration period whatever month you renew in, while a registration expired for more than a year is not charged fees retroactively (IDAPA 39.02.45.100.01).
