How Coconino 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 annually in February. The county Tax Liens page states: "The 2026 Tax Lien Sale was held on February 10, 2026, online through RealAuction." The Treasurer's Tax Certificate Process states: "The tax certificate auction must take place during the month of February." For the 2026 sale, RealAuction opened for registration and bidding on January 20, 2026 (1:00 PM MT), and batches closed on February 10, 2026 between 9:00 AM and 4:00 PM MT at 60-minute intervals.
Registration and deposit

Register on the RealAuction site at coconino.arizonataxsale.com by creating a username and password. For 2026 the site opened for registration and bidding on January 20, 2026 (1:00 PM MT), and a deposit of 10 percent of anticipated winnings was due by February 10, 2026 (4:00 PM MT). Coconino applies a Single Simultaneous Bidding Entity Rule, so each bidder may register only once and cannot have a related bidder in the sale. Bidding is a proxy auction with the interest rate bid down from the 16 percent statutory maximum to the lowest rate; payment for winning certificates is by ACH only, due February 11, 2026 for the 2026 sale. Registration stays open all year for over-the-counter purchases.

Sale format and venue
Interest ranges from 0 to 16 percent and is bid down to the lowest rate; the winner receives a Certificate of Purchase. Unsold certificates are struck to the state at 16 percent and become available over the counter. The delinquent parcel list was advertised in the Arizona Daily Sun on January 20, 2026 for the February 10, 2026 sale, and the Treasurer publishes a monthly over-the-counter list on the Tax Liens page. Over-the-counter purchases, endorsement payments, and lien research run through the Treasurer's separate GovPros portal at pay.govpros.us/az/coconino/treasurer. Statutory basis is A.R.S. Title 42, Chapter 18; the sale is offered under A.R.S. 42-18109. This is a tax-lien certificate sale only, as Arizona counties hold no tax-deed auction.

Coconino County tax sale list and auction calendar

For Coconino 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. Confirm the advertised parcel list

    Use Treasurer Tax Liens page (monthly over-the-counter list plus advertised sale property list) as a starting reference. Check which sale or list it covers; a Lands Available or office information page is separate from an auction parcel list. Ask the sale office for the advertised parcels for the auction you plan to attend.

  2. Register to bid

    Ask the Coconino County Treasurer how and when to register; many counties close registration days or weeks before the sale.

  3. Sale day

    Held annually in February. Bidding runs on RealAuction; check posted sale dates, registration status, and bidding windows there.

  4. Confirm with the office

    If the list, platform, and notice disagree, use the Coconino County Treasurer as the source to confirm which parcels are actually offered.

Before you bid in Coconino County

  1. Confirm the parcel list before pricing

    Open Treasurer Tax Liens page (monthly over-the-counter list plus advertised sale property list). Confirm whether this reference contains the auction parcels or covers a different list. Get the advertised parcel list from the county before you price a bid, and recheck it before the sale.

  2. Confirm registration and deposit

    Register on the RealAuction site at coconino.arizonataxsale.com by creating a username and password. For 2026 the site opened for registration and bidding on January 20, 2026 (1:00 PM MT), and a deposit of 10 percent of anticipated winnings was due by February 10, 2026 (4:00 PM MT). Coconino applies a Single Simultaneous Bidding Entity Rule, so each bidder may register only once and cannot have a related bidder in the sale. Bidding is a proxy auction with the interest rate bid down from the 16 percent statutory maximum to the lowest rate; payment for winning certificates is by ACH only, due February 11, 2026 for the 2026 sale. Registration stays open all year for over-the-counter purchases.

  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.

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.
