Arizona specifics, answered.
Does Arizona charge sales tax on a private car sale?
No — casual sales between private parties are exempt from Arizona's transaction privilege tax entirely. The bill of sale is your evidence: it shows MVD the seller was a private party, not a dealer. Without documentation, use tax can be assessed — which makes the humble bill of sale worth real money here.
Is Arizona's title transfer really all online?
For many sales, yes. Arizona titles live electronically in AZ MVD Now by default, and eligible lien-free, non-commercial vehicles can complete a full eTitle Transfer between two AZ MVD Now accounts — no office visit, free for the seller. Paper-title sales and edge cases still go through MVD or an authorized third-party office.
Do I still need a notary anywhere?
No. Arizona repealed title notarization in fall 2022 — eTitle transfers first, then paper titles. Older title certificates still show a notary block; MVD accepts them signed with or without a stamp. If you simply want a notarized bill of sale for your own records, that's your choice, not a requirement.
What are the two deadlines after an Arizona sale?
The seller files a Sold Notice within 10 days (online in AZ MVD Now or on paper) — it cuts off liability for the buyer's tickets, camera violations, and accidents. The buyer transfers title within 15 days, keeping in mind Phoenix- and Tucson-area vehicles need current emissions compliance to register. Plates stay with the seller, with credit available for unused registration.
