How to fill out Montana MV90A

The separate mileage sheet, for when the title itself has nowhere to record it. Montana has issued conforming titles - ones with the certification printed in the assignment - since August 1989, so most sales never need this. It comes out when the document in your hand is older or foreign and has no odometer space, when a break/bond or salvage application needs a conforming statement attached, and whenever the buyer's application and the certificate disagree about where the reading lives. Its first line is also the clearest statement of Montana's odometer rule anywhere in the division's library, and it contradicts the division's own 2026 seller leaflet.

Written against MV90A (4/26), issued under MCA 61-3-206 and the federal Truth in Mileage Act; sworn under MCA 45-7-203. The two exception boxes are not softeners for an approximate figure. Ticking not actual mileage brands the Montana title NOT ACTUAL for the rest of the vehicle's life, and the brand is carried forward to any other state it moves to. If the reading on the cluster is the reading, write it and leave both boxes alone.

Two documents, and they are not the same thing. Take the blank MV90A from the mvdmt.gov copy so you get the revision that is current today, then print our MV90A guide and keep it beside you while you fill theirs in.

Every line, in the order you meet it

1. 1
   You fill this in

   Section 1: the vehicle

   Year, make, model, style and VIN, matching the title exactly.

   Watch out: A conforming statement has to identify the vehicle by make, model, year, body type and VIN. A row with the style left blank is a statement the county can refuse as non-conforming.

2. 2
   You fill this in

   The reading, in whole miles

   Tick five or six digits, write the number with no tenths, and date the day you read it.

   Watch out: Read it on the day you hand the car over, not the day you agreed the sale. The date the odometer was read is its own field precisely because the two can differ.

3. 3
   You fill this in

   The two exception boxes

   Exceeds mechanical limits for a cluster that has rolled over; not actual mileage where the reading is known to be wrong.

   Watch out: The form's own instruction is do not check unless applicable. Either tick brands the title, and the brand follows the car out of state.

4. 4
   You fill this in

   Section 3: you, the transferor

   Name and full current address.

   Watch out: Transferor is wider than seller here - a gift, an inheritance distribution or any transfer other than creating a security interest puts you in this box.

5. 5
   The buyer fills this in

   Section 4: the buyer, the transferee

   Name and full current address, on the same sheet.

   Watch out: A conforming statement needs both addresses. A buyer who has not moved in yet should give the address they will actually be registering the car from.

6. 6
   You fill this in

   Section 5: both signatures, both dates

   You certify the reading; the buyer signs acknowledging it.

   Watch out: Do not post this for the buyer to sign later. An unacknowledged disclosure is incomplete under MCA 61-3-206(2), and a mistake on it cannot be corrected - it needs a fresh form.

What gets this one rejected

• •A reading written to the tenth of a mile. The form says no tenths and the manual repeats it - an odometer reading that specifies no tenths is part of what makes a statement conforming.
• •The word unknown. The manual is explicit that a statement that the odometer reading is UNKNOWN may not be used and is in violation of the Truth in Mileage Act; a missing or unreadable odometer is disclosed by ticking not actual mileage and noting why.
• •Only one signature. The transferee must sign to acknowledge the reading - MCA 61-3-206(2) makes the purchaser's acknowledgement part of the disclosure, not an optional courtesy.
• •A correction. The manual bars statements of fact from fixing errors on odometer statements and VIN inspections: if an error is made on one of these forms, a new form must be submitted.
• •This form where a secure power of attorney is needed. Its own header says so - where an attorney in fact is signing off for the registered owner, MV90A cannot be used.

Rules that decide whether it is accepted

• •Two thresholds, not one. MCA 61-3-206(4) exempts a 2010-model-year-or-earlier vehicle outright, and exempts a 2011-or-later vehicle once it is twenty years old or older. Everything in between discloses.
• •The division's own 2026 leaflet is wrong about this. Buying & Selling Vehicles in Montana, dated June 2026, says mileage must be disclosed on any vehicle newer than nine years, and repeats it under Title Tips. That is the pre-2021 federal rule. The statute, this form and the division's website all say otherwise.
• •Kilometres are handled on the face. The manual: cross out the word miles, substitute kilometers, and have both parties initial the change. Montana then prints the title in kilometres.
• •A repaired odometer has its own procedure. Reset to zero, a durable label on the left doorframe giving the mileage before the repair and the date it was serviced, and a title that thereafter reads not actual discrepancy.
• •Keep a copy if you are in the trade. Dealers, distributors and lessors retain a copy of every odometer statement they issue or receive for five years at their primary place of business. A private seller has no statutory duty here, which is another reason to keep the MV24.

Every line here was read off MV90A (4/26) itself — the PDF is here — and off the Montana Department of Justice, Motor Vehicle Division, Vehicle Services Bureau pages. This is plain-language help with a form, not legal advice, and where our wording and the agency's differ, theirs governs.
