The duty Wisconsin puts on you and nobody else. Within thirty days of selling a vehicle to another individual - a running car, a wreck, a junk vehicle handed over on a bill of sale - you have to tell WisDOT who bought it. There is no form, only an online service, and the department is unusually candid about the limits of what filing achieves.
Written against Seller Notification (online service), issued under Wis. Stat. s. 342.41, Identity of buyer, created by 2015 Wis. Act 60. This page describes an online service, not a document. The screens at sellernotify.wi.gov ask for a real Wisconsin driver licence number and social security digits, so nothing here is a walkthrough of a completed session - it is a list of what the statute and the department say the service collects.
There is no download link for the Seller Notification here because there is not one anywhere - Wisconsin DMV does not publish it. The card below explains where it does come from.
There is nothing to show filled in, because Wisconsin publishes no seller notification form at all. The report is taken only through the online service at sellernotify.wi.gov, behind an identity check that asks for a real driver licence number, the last four digits of a real social security number and a real date of birth. Every PDF on WisDOT's vehicle forms index was read looking for a paper version and there is none; s. 342.41(2) requires the department to accept the information electronically and that is the only route it offers. A mocked-up screenshot of a state identity service is not a sample, so this page sets out what the statute and the department say the service asks for instead.
| On the form | What to put in it |
|---|---|
| Vehicle identification number | The VIN of the vehicle sold. It is the one item the statute names first, and the whole record is keyed on it. |
| Identity of the individual buyer | Who took the car. The statute asks for the identity of the individual buyer and stops there; the online service asks for the detail. |
| Sale price | What you were paid. Not required by the words of s. 342.41, and asked for by WisDOT's service anyway. |
| Date of sale | The date that starts the thirty days, and the date you will want on your own copy of the title. |
| Your Wisconsin driver licence or identification card number, or your full name | How the service identifies you as an owner of the vehicle. A business cannot use it - the service is for individuals. |
| The last four digits of your social security number, or the full number | Asked as a second identifier alongside the licence number. |
| Your date of birth | The third identifier. All three are about proving you are the person on the vehicle record. |
There is no Seller Notification to read: Wisconsin DMV does not publish it, so nothing on this page describes its contents beyond what the agency itself says about it — that is here — and what is on the Wisconsin Department of Transportation, Division of Motor Vehicles pages. This is plain-language help with a form, not legal advice, and where our wording and the agency's differ, theirs governs.
