What is a tax certificate?
A tax certificate is a first lien against real estate (not the owner). The tax certificate sale is NOT a sale of real property, nor does a tax certificate give the certificate holder a direct means to acquire a property.

It is your sole responsibility to research any tax lien certificates that you intend to buy. You can see additional property and tax information for any particular certificate by clicking on the account number. Research the property carefully as all tax certificate purchases are final.

Buyer beware:  As with all investment opportunities, there is an element of risk.

When does the tax certificate sale take place?
The sale opens in early February and closes in late February each year.

Starting in early February:
  • Items for sale are advertised in the Kingman Daily Miner and on
  • Bidders can begin to register for the sale (submit W-9 forms, pay deposits, get bidder numbers)
  • Bidders can begin to submit bids
On or before February 28:
  • Bid submission ends
  • Sale results are generated
For exact dates, please see the Auction Schedule. All activity related to registration, bidding, and certificate awards takes place on

How do I register for the sale?
All bidders who wish to participate in the sale must perform the following steps on
  • Obtain a User ID and password for the web site by clicking the "Register" link on the auction site home page and completing the required form.
  • Submit an IRS form W-9. Please note that you can only submit or modify your W-9 while a sale is open. You will be assigned a bidder number after you successfully submit your W-9.
  • Set a Budget amount (the most you are willing to spend in the sale)
  • Pay a deposit of at least 10% of your anticipated purchases. Deposits will only be accepted via ACH and while a sale is open.
How do I submit my bids?
You can submit your bids on the Bid page individually, as a group (using a saved list), or via a file upload. You must complete all of the registration steps before you are allowed to submit bids.

How do I pay for certificate purchases?
Payment must be made by ACH using the Pay for Certificates button on the My Account page. The button is activated once the last batch in the sale closes and any final data updates are complete. The deadline to pay is listed on the Auction Schedule. If you fail to pay by the deadline, you may forfeit your security deposit and certificate purchases.


What is the auction process?
Certificates are sold in the order advertised. Bidding begins at 16 percent (the maximum rate) and bids down in increments of one percent. Each certificate is sold individually to the bidder offering the lowest interest rate. In the case of a tie at the lowest rate, the winner will be selected using a random number generator in the auction software. Items that receive no bids are "struck" to the state. Bids are accepted at 0.00% (zero), but certificates awarded at this rate WILL NOT accrue interest. Bids at 0.00% will not be treated as Proxy bids in sales using Proxy Bidding.

For more information, please see Suggestions for Participating in the Tax Sale.

Is there a cost to participate?
Registration on the web site is free. You only need to make payment for a refundable security deposit, and to pay the balance due for any certificate purchases. All purchases are final and bidders can only pay the full amount due for all awarded certificates at the end of the sale.

What is a batch?
A batch is a subgroup of the list of auction items. The list is divided into batches to make the bidding process more efficient, and enable participants to manage their bids and budgets.

Do I have to bid on all the items in a batch?
NO. Each tax certificate in each batch is auctioned independently of every other tax certificate.

What happens to my security deposit if I don't win any certificates?
The Treasurer will issue refunds approximately four weeks after the close of the sale. The refund will be made by ACH to the account you used to submit your deposit. You will receive an email confirmation when the refund is initiated.

What is Proxy Bidding?
In a live auction, bidders lower their bids in one percent increments until they are the only bidder left or until the interest goes below their acceptable minimum level, at which point they would drop out.

Proxy bidding is a form of competitive sale in which bidders enter the minimum interest rate that they are willing to accept for each certificate. The auction system acts as an electronic agent, submitting bids on behalf of each bidder until their minimum bid rate is met. Using the proxy system the electronic agent keeps lowering your bid in one percent increments until you are either the only bidder left, (in which case you get the certificate at one percent lower than the previous bid) or until you reach the floor you have set. Note:
  • Zero percent bids will not be treated as proxy bids. They will be awarded at zero.
  • If you are the only bidder on a given certificate and your minimum rate is greater than zero percent, the electronic agent will submit a bid of 16 percent on your behalf.
  • In the case of a tie at the winning bid rate, the system awards the certificate to one of the tied bidders through a random selection process using a random number generator.
  • In no case will a bidder be awarded a certificate at a rate lower than their specified minimum acceptable rate.
  • Certificates that receive no bids after all batches are closed will be struck to the state at 16 percent.
  • For more information about using Proxy Bidding in sales on, see Suggestions for Participating in the Tax Sale.
Does my budget amount limit the number of bids I can submit?
No. You can submit an unlimited number of bids regardless of your budget amount. However, you will not be awarded an item if the award would cause the value of your purchases to exceed your budget amount.

Is my Budget amount automatically 10x my deposit amount?
No. The maximum allowable Budget you can set is 10x your deposit amount, but you have to enter what you want your Budget to be. You can modify your Budget any time before the end of the sale, as long as you have at least 10% of that amount submitted as your deposit.

Where can I find sale results?
You can see results by logging in to, entering the auction, and clicking on the Results tab in the upper right-hand part of the page. Clicking on the winning bid for any certificate will display a list of all submitted bids in a new window.

How do I receive my investment income?
The Treasurer remits the principal (face amount of certificate) and the interest earnings if the property taxes are paid by the owner or an agent.

Grant Street Group's $10.00 auction fee and a $10.00 processing fee (per Statute 42-18116,c) charged by the Treasurer are non-refundable and not interest-bearing. All other fees included in the face value of the certificate are refunded at redemption and are interest-bearing.

Can I pay the taxes and own the property?
NO. You have not purchased property. A tax certificate is an investment. This investment does not convey any property rights or ownership to the certificate holder. A certificate holder is an investor, and the purpose of purchasing certificates is to earn interest on your investment, not to acquire property.

Can an interest rate be changed after the sale?
If a certificate should be cancelled or reduced, the interest earned will be 10% per year, simple interest or the rate of interest bid at the tax certificate sale, whichever is less on the cancelled or reduced amount. Bankruptcy rulings may also affect interest rates.

Why would a certificate be canceled or reduced?
A certificate could be canceled or reduced for various reasons such as to correct errors, omissions, or double assessments, or when ordered by a court.

Are tax certificates transferable?
Certificates may be transferred by completing a re-assignment form (provided by the Treasurer's Office) and paying the applicable fees of $10.00 per parcel prior to redemption.

What happens to certificates that receive no bids in the sale?
Certificates that receive no third-party bids are issued to the State. State held tax certificates may be acquired by individuals after the close of the tax sale. The Treasurers Office will announce the date(s) these certificates become available.

What is the life of a tax certificate?
Certificates are dated as of the date the purchase was made. Ten years later, if the purchaser has taken no additional action to foreclose the tax lien, the lien expires and is voided. No payments will be made to the purchaser. A purchaser may initiate a Judicial Foreclosure action after three years from the initial purchase date.

What is the tax deed process?
Any certificate holder including the County may file an Action to Foreclose in the Superior Court of Mohave County three years from the date of the sale.

Where can I find the Arizona Revised Statutes that pertain to tax liens?
Statutes are available online (Title 42, Chapter 18, beginning with Article 3).
