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.
