Tax Deed

Arizona tax lien auctions are annual, February-based events where investors bid down the interest rate (capped at 16%) on delinquent tax debt. The purchaser receives a certificate of purchase, not the property. If the owner fails to redeem within three years, the investor may initiate a judicial foreclosure to potentially acquire the deed.

Sale mechanics

Arizona conducts tax lien sales via a reverse auction where bidders compete to accept the lowest interest rate. Auctions are held annually, often online through platforms like RealAuction. Bidders must register with the county treasurer, provide identification, and submit a deposit. The minimum bid is the total of delinquent taxes, interest, penalties, and fees, with full payment typically due shortly after the sale.

Post-sale obligations

Purchasers do not gain possession or entry rights during the redemption period. If the lien is not redeemed within three years, the purchaser may initiate a judicial foreclosure action in Superior Court to obtain a treasurer's deed. The lien expires 10 years after the original sale if no foreclosure action is commenced.
