Arizona Tax Deed Sales 2026

How tax sales work in Arizona

Arizona counties sell tax lien certificates, not property. Each county treasurer holds one sale in February covering parcels with taxes delinquent from the prior year. Bidders compete on the interest rate they will accept, starting at 16 percent and moving down; the lowest rate wins. Certificates that draw no bid are assigned to the state and can later be bought over the counter from the treasurer at the full 16 percent rate, which is where many smaller investors start. Maricopa, Pima and most larger counties run the sale online through a contracted platform, while some rural counties still hold in-person sales.

Redemption and interest

The owner or any party with an interest may redeem by paying the certificate amount plus the winning interest rate, accrued monthly. Three years after the sale the certificate holder may file a judicial foreclosure action in superior court to end the redemption right and obtain a treasurer’s deed. The owner can still redeem until judgment, and if they do the holder recovers interest and, in many cases, court costs and fees under the statute. Holders should pay subsequent years’ taxes and endorse them onto the certificate, which earns the same rate and prevents a competing certificate from being sold on the parcel.

When and where sales happen

The statutory sale window is February each year. Lists are published in January, and the online auctions typically run for several days. Over-the-counter purchases of state-held certificates are available year-round from each treasurer, subject to county procedures.

What to check before you bid

Look at the assessor’s full cash value against the lien amount to gauge how likely redemption is and what you would own if it never comes. Check the county recorder for mortgages, IRS liens and HOA claims; a tax lien is senior to most, but foreclosure notice requirements are strict. Confirm the parcel has legal access and is not a sliver or remainder. Review the treasurer’s bidder rules on deposits, batch closing and proxy bidding, since these differ by county.

How DeedScore helps here

DeedScore pulls each county’s February certificate list into one dataset, scores parcels from 0 to 100 using assessed value, lien size and location factors, and flags recorded liens that could complicate a later foreclosure. The calendar tracks each county’s sale dates and list release.
