Indiana Motor Carrier Services: IRP and Base Plates

Quick Answer

Indiana DOR Motor Carrier Services (7811 Milhouse Road, Indianapolis; 317-615-7200) handles all Indiana IRP — apportioned plates cannot be purchased at the BMV — plus Base Plate Registration for intrastate fleets of 5 or more vehicles at 11,001 pounds and up. New IRP and IFTA accounts require an appointment; renewals open online 3 months early with a 10% penalty for paying late. Form 2290 proof (stamped Schedule 1 or e-file watermark; cancelled-check fallback) is required at a declared gross weight of 55,000 pounds or more — and trucks plated over 48,000 but at or under 66,000 pounds with a lower taxable weight file a sworn exemption affidavit (State Form 56500) instead, at every registration.

Indiana splits truck registration between two agencies: the BMV handles titles, farm plates, and smaller operations, while the Department of Revenue’s Motor Carrier Services division runs IRP, IFTA, intrastate authority, oversize/overweight, and — increasingly — ordinary base plates for mid-size fleets.

Two Indiana rules have no parallel in neighboring states: the one-time, unchangeable staggered renewal month, and the Form 56500 affidavit band for trucks plated heavy but taxed light.

MCS or BMV? The five-vehicle line

IRP is MCS-only: Indiana apportioned plates are available through Motor Carrier Services (online processing is 24/7) and cannot be purchased at the BMV. On the intrastate side, Indiana law routes carriers with five or more vehicles registered at 11,001 pounds or more through MCS Base Plate Registration instead of the BMV — the migration has been rolling fleets over cycle by cycle.

New IRP and IFTA accounts require an appointment at the MCS Customer Service Center (317-615-7200, option 2 for IRP; weekdays 8 a.m.–4:30 p.m. ET; or irpnewaccount@dor.in.gov); walk-in service covers other transactions. MCS assigns a staggered renewal month at setup — and once selected, it cannot be changed. Initial registration is prorated 6 to 18 months to land on your month.

Renewals open online three months before your due date, and paying after it adds a 10% penalty. 45-day temporary permits cover newly added vehicles — but not renewal vehicles awaiting payment.

The 2290 rules — and the 56500 affidavit band

The BMV requires the Form 2290 during registration, amendment, and renewal transactions for commercial and farm trucks, semi-tractors, and for-hire buses at a declared gross vehicle weight of 55,000 pounds or more; on the MCS side, proof of the current federal tax must be verified for IRP accounts and renewals. Accepted proof: a Schedule 1 stamped by the IRS (the e-file watermark qualifies) or an unstamped 2290 with both sides of the cancelled check.

Indiana plates run on declared gross weight — empty weight plus the heaviest load of the year — while the federal tax runs on taxable gross weight. When they diverge, State Form 56500 bridges the gap: a truck plated over 48,000 but at or under 66,000 pounds whose taxable gross weight is under 55,000 can skip the 2290 by filing the sworn exemption affidavit at every new and renewal registration. Above 66,000 pounds declared, the affidavit is off the table and 2290 proof is required outright.

New purchases are exempt from the state proof requirement through the last day of the month following the month of purchase — exactly the federal filing deadline, so filing on the federal clock satisfies Indiana automatically.

CVET and the farm lane

Indiana folds a Commercial Vehicle Excise Tax (CVET) into every commercial registration — paid with the plates in lieu of personal property tax, taking the vehicle off the county property tax rolls entirely. Farm plates (declared GVW over 11,000 pounds, use restricted to the owner’s agricultural operation) pay CVET at 50% of the non-farm rates, are exempt from IRP and IFTA, and skip the USDOT number if they never leave Indiana. At 55,000 pounds declared, the 2290 requirement applies to farm trucks at registration and every renewal.

Frequently asked questions

Where do I log in for Indiana IRP?
Through DOR Motor Carrier Services’ online system (linked from the DOR motor carrier pages) — processing is available 24/7 once your account exists. New IRP or IFTA accounts require an appointment first: 317-615-7200, option 2, or irpnewaccount@dor.in.gov.
What is Indiana State Form 56500?
A sworn affidavit exempting a truck from 2290 proof when its declared weight is over 48,000 but at or under 66,000 pounds while its federal taxable gross weight is under 55,000. It must be filed at every new and renewal registration — and above 66,000 pounds declared, it is not available at all.
Can I change my Indiana staggered renewal month?
No — MCS states that once the staggered month has been selected, it cannot be changed. Choose deliberately at account setup; the initial term is prorated 6 to 18 months to reach it.
When does a new truck need 2290 proof in Indiana?
After the last day of the month following the month of purchase — which is also the federal filing deadline. File the 2290 on time with the IRS and the watermarked Schedule 1 exists before any Indiana transaction can demand it.
