How Mills 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.

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.

County notes
- Mills County runs a hybrid format: the Mills County Treasurer conducts the annual tax sale from the courthouse at 418 Sharp Street in Glenwood, but all bidding is placed online through Iowa Tax Auction.
- Registration is a hard gate. For the June 15, 2026 sale it closed at 11:59 p.m. on June 11, 2026, and the packet states mailed or emailed registrations are not accepted.
- The parcel list is not hosted on the county website. Registered bidders view it on the auction platform, and the newspaper list runs in The Malvern Leader / Beacon-Enterprise in Malvern.
- Bidding is bid-down ownership percentage from 99 percent to 1 percent, and Mills County does not use batches, so parcels are offered in published order.
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.
