Pennsylvania Car Bill of Sale: Form MV-4ST + Notarization
Pennsylvania's structural quirk: title signatures must be notarized. Most PA private vehicle transfers happen through tag service centers, AAA offices, or notaries that handle the notarization, Form MV-4ST filing, tax payment, and plate issuance in one visit.
Is a bill of sale required in Pennsylvania?
Recommended. PA's title-transfer process focuses on the title (notarized) and Form MV-4ST (combined title application + sales tax return).
Notarization
The title signature must be notarized in PA. The bill of sale itself is recommended but doesn't strictly require notarization.
State-specific form
Form MV-4ST (Vehicle Sales and Use Tax Return / Application for Registration) combines the title application and sales tax return. Filed at title transfer.
The bill of sale should include:
- Seller's full legal name, address
- Buyer's full legal name, address
- Vehicle year, make, model, body type, VIN
- Odometer reading

The buyer pays at title transfer.
