Residents who have snowmobiles, all-terrain vehicles (ATVs), off-road utility vehicles (ORVs) or off-road motorcycles (ORMs) registered with the Iowa Department of Natural Resources (DNR) need to renew their registrations by Dec. 31.
Registrations can be renewed by any county recorder office or on the DNR’s website at iowadnr.gov. User permits can be purchased at any location where hunting licenses are sold, including the Iowa DNR website.
After Dec. 31, customers can still renew their registration, but they will pay a $5 penalty.

Resident snowmobiles
Iowa residents are required to have and display a current Iowa DNR registration and user permit on their snowmobile in order to lawfully operate on any public land or public ice in Iowa.
Nonresident snowmobiles
Nonresident snowmobilers are required to have and display a current registration from their home state and display a current Iowa DNR user permit. If a nonresident resides in a state that does not require or offer snowmobile registration, the only requirement is to display an Iowa DNR user permit.

Resident off-highway
Iowa residents must have and display a current Iowa DNR registration on their ATV, ORV or ORM to operate on any designated public land or ice in Iowa. Residents are not required to display an Iowa DNR user permit.

Nonresident off-highway
Non-residents are required to have their machines registered in their home state and display an Iowa DNR user permit.
