How Pinal County sells delinquent taxes

From lien to deed

Arizona does not hold county tax deed auctions. Instead, a certificate of purchase holder whose lien has not been redeemed may file a judicial action to foreclose the owner's right to redeem, but only after three years have passed since the tax lien sale.

When it runs
Held online each year in February (A.R.S. 42-18112) for the prior year's delinquent taxes. The Treasurer's booklet states the sale "is held every year in February," and the vendor site opens for parcel viewing, new-bidder registration, and bidding about two weeks before the sale.
Registration and deposit

Register online at the RealAuction vendor site (pinal.arizonataxsale.com) at least one day before the sale. Create a username and password to be assigned a bidder number, then submit an initial deposit by wire or ACH (the greater of $500 or 10% of your anticipated bid) at least one day prior. ITIN, IRS Form W-8, and other non-US registration types are not accepted. Bidding opens at the 16% statutory maximum and is bid down; the certificate is awarded to the bidder accepting the lowest interest rate.

Sale format and venue
The sale runs in timed batches on sale day (first batch closes 8:00 am MST, successive batches close hourly, final batch closes 4:00 pm MST). Winning bidders must check out and pay by wire or ACH within 24 hours of the sale close. The parcel list is published in the county's newspaper of general circulation about two weeks before the sale and posted on the vendor site for viewing and bidding. County-held certificates not sold at auction can be bought online from about the first week of March through the end of December at the full 16%.

Pinal County tax sale list and auction calendar

For Pinal County tax sale 2026 searches, use the county-run sources below rather than a copied parcel list, and confirm the parcel, registration cutoff, deposit, and payment deadline against the county before you bid.

  1. Get the advertised list

    Use Tax lien sale parcel list and online bidding (RealAuction) for the current advertised parcels, then recheck it before the auction.

  2. Register to bid

    Ask the county office how and when to register; many counties close registration days or weeks before the sale.

  3. Sale day

Before you bid in Pinal County

  1. Start with the live sale list

    Pull the current advertised parcels from Tax lien sale parcel list and online bidding (RealAuction). Lists can change before the sale, so recheck the county source before you price a parcel.

  2. Confirm registration and deposit

    Register online at the RealAuction vendor site (pinal.arizonataxsale.com) at least one day before the sale. Create a username and password to be assigned a bidder number, then submit an initial deposit by wire or ACH (the greater of $500 or 10% of your anticipated bid) at least one day prior. ITIN, IRS Form W-8, and other non-US registration types are not accepted.

  3. Check the state rules that change the bid

    Read the Arizona due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth.

  4. Set a walk-away number

    Work out what the parcel is actually worth with the rural land value estimator, then turn it into a ceiling with the tax deed max-bid calculator.

Over-the-counter (leftover) purchases

Liens that receive no bid are struck to the state. Any person may later buy a state-held certificate over the counter by assignment from the county treasurer, paying the amount due plus subsequent taxes and a small assignment fee. Assigned state certificates earn the full 16 percent.

County notes

  • Arizona is a tax-lien state: Pinal County sells tax lien certificates each February and issues a Certificate of Purchase; there is no county tax-deed auction (A.R.S. Title 42, Chapter 18).
  • Bidding starts at the 16% statutory maximum and is bid down to the lowest rate accepted; certificates begin accruing interest on March 1 and expire 10 years after purchase (A.R.S. 42-18127).
  • County-held certificates not sold at the February auction can be purchased online (assignment purchase) from about the first week of March through the end of December at the full 16%.
  • Minimum bidder deposit is $500 or 10% of the anticipated bid, whichever is greater, submitted by wire or ACH at least one day before the sale.
  • Separately, the Pinal County Board of Supervisors sells parcels deeded to the State of Arizona (A.R.S. 42-18302, Article 7) through Special Services ([email protected], 520-866-6470); this state deed sale is outside the annual tax lien sale and is not a Treasurer tax-deed auction.

Arizona rules

Max interest rate
16% per year, bid down at auction
Minimum return
No statutory minimum; interest accrues at your bid rate
Redemption
The owner or any interested party can redeem the lien at any time until the right to redeem is foreclosed by the court. A certificate of purchase holder cannot begin a foreclosure action until three years after the sale, and the lien becomes void if no foreclosure is commenced within ten years after the month the certificate was acquired.
Surplus proceeds
If the court forecloses the right to redeem, the county treasurer issues a treasurer's deed conveying the parcel to the certificate holder. Because the property is conveyed by deed rather than sold at auction, there is no auction surplus to distribute.
Governing statute
A.R.S. Title 42, Chapter 18

A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
