Montana MV24 — Bill of Sale

About MV24

Official name: Montana Form MV24 — Bill of Sale

Issued by: Montana Motor Vehicle Division

Purpose: Documents a private vehicle sale in Montana as an optional record; the transfer itself runs on the seller-signed title and the MV1 title application at the county treasurer's office. No sales tax is owed.

When required: Not required for an ordinary sale with the title in hand; the MV24 is one optional document in some lost-title and bonded-title cases. The buyer files the title paperwork at the county treasurer's office within Montana's 40-day window. For model year 2011 and newer vehicles, the MV24 directs you to the separate MV90A odometer disclosure.

What MV24 records

• The form (MV24, 12/23) must be completed in its entirety, and Montana authorities can reject any form that has been altered.
• The amount the seller received, and the buyer's name, address and driver license, FEIN, tribal ID or corporate ID number.
• The vehicle or vessel: year, make, model and VIN or hull ID number, and whether it was sold for parts only.
• Whether a title is available. If not, the seller certifies the vehicle is not "mechanically functional" (it needs more than minor reconditioning) and gives its current value.
• The odometer: for model year 2011 and newer, use the separate Odometer Disclosure Statement (MV90A). The buyer signs to confirm they saw the seller's odometer certification.

What the seller certifies

• For an electronic title: that the seller does not hold a paper title, owns the vehicle, authorizes the transfer to the buyer named, and has not already sold it to someone else.
• That the seller has the right to sell, and will warrant and defend the title against all claims except the lender listed on the Montana title application.
• Under penalty of law (MCA 45-7-203), that the information is true and the signer is the person named. All owners must sign.

When a notary is needed

The form says a notary is needed only when MV24 is used with an Application for Break/Bond Title (MV10), or when an electronic record transfer takes place. Separately, Montana dropped the notary requirement for title signatures in October 2025 (HB 165).

Deadline and costs

• The buyer has 40 calendar days from the purchase to title and register the vehicle. After that, a $10 late penalty applies.
• Montana has no sales tax. The buyer pays registration fees, and some counties add a local option motor vehicle tax.
