See Title & Registration Fees

 

International Registration Plan (IRP) License Plates

Vehicles used to transport items weighing more than 500 pounds (for business purposes) must be commercially licensed. If your vehicle travels only in South Dakota, you must obtain an in-state commercial license from your local county treasurer’s office. However, if you use that vehicle outside South Dakota, you must either obtain a trip permit or have an IRP license (PDF) (also referred to as a prorate license). These licenses are issued only by the Office of Prorate and Commercial Licensing, a section of the Department of Revenue Motor Vehicles Division. For more information, visit SDTruckInfo.com.

Heavy Vehicle Use Tax (HVUT)

Heavy Vehicle Use Tax (HVUT) is paid by anyone who registers a heavy highway motor vehicle in their name with a taxable gross weight of 55,000 pounds (28 ton) or more. The applicant is required to file a Form 2290 with the IRS. HVUT is filed annually. The tax period of Form 2290 is July 1st - June 30th of the following year. When vehicle owners purchase a vehicle over the gross weight requirement they have 60 days to file Form 2290 with the IRS in which they are under pending status and the tonnage decals are issued. At the time of registration, proof of payment of the heavy vehicle use tax is required to be provided within 30 days. The tonnage decals are not issued until this information is received.
