How Audubon County sells delinquent taxes
From lien to deed
Iowa holds no separate tax deed auction. The county treasurer makes out a deed for each parcel sold and unredeemed immediately after 90 days have expired from the date of completed service of the notice of expiration of the right of redemption, once the holder returns the certificate of purchase and pays the deed and recording fees.

When it runs
Registration and deposit
Registration is handled directly by the Treasurer's Office and must be completed in advance. The 2026 packet states registration "must be completed and returned by Thursday, June 11, 2026 at 4:00 p.m." and that there is "No registration the day of the tax sale." A $25 non-refundable registration fee must accompany the documents. Required paperwork is a Bidder Registration Form, a W-9, and, when bidding through an agent, an Authorization to Represent Bidder form. An entity bidder must hold a federal tax identification number plus either a designation of agent for service of process on file with the Iowa Secretary of State or a verified statement of trade name on file with the Audubon County Recorder. The Treasurer's page allows 3 bidders per entity, with each bidder permitted to represent 6 companies. All bidders must be 18 or older as of the sale date, and a bidder may not have a vested interest in a parcel offered.

Check the state rules that change the bid
Read the Iowa due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth.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
unsold certificates
Two routes reach parcels after the June sale. Parcels that remain unsold for want of bidders are carried to adjourned sales, which the treasurer sets at intervals of not more than two months until the next annual sale. Separately, certificates struck to the county at the public bidder sale may be assigned by the county for the total amount due on the date of assignment, or for a compromised amount, under a written agreement filed with the treasurer and a 10 dollar assignment transaction fee. Ask the county treasurer which county-held certificates are available for assignment.

- Email contacts listed on the Treasurer's portal page are dcampbell@auduboncountyia.gov and treasurer@auduboncountyia.gov.
- The phone number 712-563-2741, which appears in some third-party search listings alongside Audubon tax sale information, belongs to the Audubon Advocate newspaper that publishes the sale notice, not to the Treasurer's Office. The Treasurer's number is 712-563-2293.
- The Treasurer page at auduboncountyia.gov/county-information/treasurer.aspx currently renders another Iowa county's treasurer content, including a different staff list, street address, and phone number. Investors should rely on the Iowa County Treasurers portal page for Audubon contact details until the county site is corrected.
- Certificate holders can pay subsequent taxes by registering as a Tax Sale Investor at iowatreasurers.org under the Online Services menu, at a cost of $0.25 per parcel paid, or by written request to the Treasurer at $2.00 per parcel under Iowa Code Section 445.5(3).
- Regular tax sale certificates allow the 90-day Notice of Right of Redemption after one year and nine months from the sale date. Public bidder certificates, marked with an asterisk on the sale list, allow that notice after nine months.
- The Treasurer cancels a certificate if the holder has not filed an affidavit of service under Iowa Code 447.12 within three years of the sale. The Treasurer's tax sale deed issuance fee is $25.00 per parcel, due with the certificate and recording fees within 90 calendar days after the redemption period expires.

Iowa rules
- Minimum return
- No statutory minimum return; what you earn is set by the share of ownership taken at the sale
- Redemption
- A parcel may be redeemed at any time before the right of redemption expires. After one year and nine months from the date of sale, the certificate holder may serve a notice of expiration of the right of redemption on the person in possession, the person in whose name the parcel is taxed, and every mortgagee, contract vendor, recorded lessor, and other party of record. The right of redemption then ends 90 days after that service is complete, which means the affidavit of service has been filed with the county treasurer. Three shortened tracks exist: nine months from a public bidder sale under section 446.18, and three months from an abandoned-property or public nuisance sale under section 446.19A or 446.19B. After the treasurer delivers the deed, redemption is possible only through an equitable action in district court, and only by a person who could have redeemed during the 90-day window.
- Surplus proceeds
- No surplus arises. The deed conveys the parcel to the certificate holder rather than selling it to the highest bidder, so there are no excess proceeds to distribute. Where the winning bid was less than 100 percent, the deed conveys only that undivided percentage interest in the parcel.
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.
