A field-by-field walkthrough of the Massachusetts RMV-1 (Registration and Title Application) for licensed used car dealers — what goes in every section, who signs what, and the documents you attach. Verified against the official form as of June 2026.
This guide is informational and does not replace the official Massachusetts instructions. Always confirm the current form and procedure with the Massachusetts RMV before you file.
DealerVLO fills the official Massachusetts RMV-1 straight from your deal — VIN-decoded vehicle, buyer, co-buyer, and sale price already in place. $99/month, free to try — no credit card.
If you sell cars in Massachusetts, the RMV-1 is the form that actually transfers the vehicle. Until it's completed, stamped by an insurance agent, and filed, your buyer can't title the car, can't register it, and can't legally drive it off your lot. It's the single most important piece of paper in a Massachusetts deal jacket.
The form looks intimidating because it packs owner, vehicle, title, lien, and dealer information onto one page — but each section is short, and as the dealer you only complete part of it. This walkthrough covers every section, shows exactly who is responsible for each field, and flags the errors that send a title application back from the RMV.
Massachusetts has consolidated the old RMV-1 (registration/title) and RMV-3 forms into a single Registration and Title Application (RTA). Most dealers, insurance agents, and title runners still call it “the RMV-1,” and the published fillable PDF (TTLREG100) carries the same section layout described below. If your form's header reads “Registration and Title Application,” you're in the right place.
Gather these before you complete the RMV-1. A missing attachment is the number-one reason the the Massachusetts RMV bounces a title application back.
This is the buyer (the new owner), not you. Enter the primary owner's full legal name, date of birth, and Massachusetts residential address exactly as they appear on the buyer's license. A co-buyer goes in the Owner 2 fields.
| Field | Who fills it |
|---|---|
Owner 1 full name (Last, First, Middle) From the buyer's license — match it exactly. | You (dealer) |
Owner 1 date of birth | You (dealer) |
Owner 1 Massachusetts address | You (dealer) |
Owner 2 / co-buyer (if any) Only if the deal has a co-buyer. | You (dealer) |
Social Security number Often left blank by the dealer and completed at the counter — it isn't on the deal jacket. | Buyer |
Driver's license number | Buyer |
Everything that identifies the car. Most of this decodes straight from the VIN. Double-check the VIN character-for-character against the title and the dash — a single transposed digit is the most common rejection.
| Field | Who fills it |
|---|---|
VIN Verify against the title and the vehicle, not just your records. | You (dealer) |
Year, make, model | You (dealer) |
Body style / type | You (dealer) |
Color Use the RMV's color names, not the manufacturer's marketing name. | You (dealer) |
Cylinders, fuel type, transmission | You (dealer) |
Odometer reading Must match the odometer disclosure on the assigned title. | You (dealer) |
Registration / plate type Passenger, commercial, etc. — confirmed with the buyer. | Buyer |
Where the prior title came from. For a used car you sold, you're carrying forward the previous title's number and state, and confirming the vehicle's condition and title type.
| Field | Who fills it |
|---|---|
Previous title number | You (dealer) |
Previous title state | You (dealer) |
Vehicle condition “Used” for a dealer-sold second-hand vehicle. | You (dealer) |
Title type “Clear” by default — change only for salvage/rebuilt/reconstructed titles. | You (dealer) |
If the buyer paid cash, leave this blank. If you arranged or assigned financing, record the lender so the lien is printed on the new title and the RMV mails the title to the right place.
| Field | Who fills it |
|---|---|
Lienholder legal name Cash deal? Leave the whole section empty. | You (dealer) |
Lienholder mailing address | You (dealer) |
Date of lien Usually the sale date. | You (dealer) |
This is you. Your dealership's name and license number identify the selling dealer; the sale date and price drive the excise tax calculation. Be accurate — the price here should match your bill of sale.
| Field | Who fills it |
|---|---|
Dealer name | You (dealer) |
Dealer license number | You (dealer) |
Sale date | You (dealer) |
Sale price Match the bill of sale; this is what excise tax is computed on. | You (dealer) |
Trade-in indicator + allowance Check the trade-in box and enter the allowance when there's a trade on the deal. | You (dealer) |
The RMV will not process the form without proof of active Massachusetts coverage. The buyer's insurance agent stamps and signs this block. You can't complete it yourself — it has to be a licensed MA agent.
| Field | Who fills it |
|---|---|
Insurance company + policy number | Insurance agent |
Agent stamp Required — the form is rejected without it. | Insurance agent |
Agent signature + date | Insurance agent |
The form is signed in person. The buyer signs as the new owner; you sign as the selling dealer. Don't pre-sign — both signatures should be wet-ink at the desk when the deal closes.
| Field | Who fills it |
|---|---|
Owner / buyer signature | Buyer |
Dealer signature | You (dealer) |
The single most common rejection. The RMV-1 is not valid until a licensed Massachusetts insurance agent stamps Section F. Send the buyer to their agent (or your in-house agent) before filing — a printed RMV-1 with an empty insurance block gets handed right back.
The VIN on the RMV-1, the assigned title, and the vehicle must be identical, and the odometer reading must match the disclosure on the title. Verify all three against each other, not just against your DMS record.
Excise tax is calculated from the price in Section E. If it disagrees with your bill of sale, expect questions and delay. Keep the two documents in sync, and apply the trade-in allowance correctly when there's a trade.
Use the buyer's full legal name exactly as printed on their Massachusetts license — including middle name or suffix. A nickname or dropped middle initial can stall the title.
If the car is financed, the lender's exact legal name and address must be in Section D, or the title prints without the lien recorded — a serious problem for the lender and for you.
Yes. Massachusetts merged the old RMV-1 and RMV-3 forms into a single Registration and Title Application (RTA). The industry still calls it “the RMV-1,” and the section layout — owner, vehicle, title, lien, dealer, insurance, signatures — is the same. If your form header says Registration and Title Application, that's the current RMV-1.
The dealer completes most of it: owner information from the buyer's license, the vehicle details, title and lien information, and the dealer/sale block. The buyer provides their Social Security number, license number, and plate type, and signs at the desk. A licensed Massachusetts insurance agent stamps and signs the insurance section. All three are needed before filing.
Massachusetts requires proof of active insurance before a vehicle can be registered. The RMV will not process the RMV-1 until a licensed MA insurance agent stamps and signs the insurance block confirming coverage. This is the most common reason a form gets rejected, so handle it before you file.
At the Massachusetts RMV — either in person at a service center or through a title/registration service (a “runner”) that many dealers use to avoid the counter. You'll submit the completed RMV-1 along with the assigned title (or MCO), the bill of sale, and the insurance stamp. Plates are typically issued the same day; the printed title is mailed several weeks later.
Registration and plates are usually handled the same day the RMV-1 is processed. The physical title is mailed afterward and commonly takes about six to eight weeks. If there's a lienholder, the title is mailed to the lender; on a cash deal it goes to the owner.
You can complete the official fillable PDF on a computer and print it, which is faster and more legible than writing by hand — but the signatures and the insurance stamp still happen in person on the printed form. Dealer software like DealerVLO populates the official fillable PDF from your deal jacket automatically, so you only hand-add the few fields collected at the counter.
Don't scribble over it. A clean, correct form processes faster — cross-outs and white-out invite rejection. If you catch an error, reprint the form with the correction. If you generate the RMV-1 from your deal data, fix the underlying record and re-print so the corrected version is clean and consistent.
DealerVLO fills the official MA RMV-1 straight from your deal jacket — VIN-decoded vehicle, buyer, co-buyer, lienholder, and sale price already in place. Print, sign, and file in about 90 seconds. $99/month. No credit card to start.
