How Fremont 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
Third Monday in June. The Treasurer's tax calendar lists a "Third Monday in June annual tax sale of outstanding property taxes, manufactured homes, mobile homes, weed assessments, special assessments, rates or charges, and drainage taxes." The most recent posted terms document reads: "The 2024 annual Tax Sale will be held by the Fremont County Treasurer on Monday, June 17, 2024, in the Treasurer's office on the first floor of the Fremont County Courthouse, 501 Filmore, Sidney, IA beginning at 9:00 a.m." Bidding closes at 10:00 a.m. that same morning. An adjourned sale is held on any business day after the annual sale when bidders are present and parcels remain unsold.

Sale format and venue
Fremont County runs Iowa's standard annual tax sale as an online auction. Bidders place bids through www.iowataxauction.com while the Treasurer conducts the sale from the office on the first floor of the courthouse at 501 Filmore in Sidney. Bidding is a bid-down of the undivided percentage interest, starting at a 100% undivided interest with bid downs in whole percentage points from 99% to 1%; the county does not use batches. When the sale closes at 10:00 a.m., each parcel's certificate goes to the bidder naming the smallest percentage, and ties at the smallest percentage are broken by random selection. Bids may be uploaded before the sale opens but are not applied until 9:00 a.m. on sale day, and no bid may be withdrawn. Winners are invoiced at close and charged by ACH debit from the account used for the registration fee; the amount due covers delinquent taxes, special assessments, interest, collection fees, publishing costs, and a $20.00 certificate fee per certificate. Certificates typically arrive 7 to 15 days after the sale. Assigning a certificate costs the assignee a $100.00 assignment transaction fee. The newest full terms-and-conditions notice posted on the county website covers the 2024 sale, so confirm the current year's sale date, registration window, and fee with the Treasurer before bidding.

Fremont County tax sale list and auction calendar

For Fremont 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 County-held tax sale certificates (non-redeemed list, PDF) 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

    Iowa holds no tax deed auction. Bidding runs on ZEUS; check posted sale dates, registration status, and bidding windows there.

  4. Confirm with the office

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

Before you bid in Fremont County

  1. Start with the live sale list

    Pull the current advertised parcels from County-held tax sale certificates (non-redeemed list, PDF). Lists can change before the sale, so recheck the county source before you price a parcel.

  2. Confirm registration and deposit

    Registration is online at www.iowataxauction.com; the county accepts no mailed or emailed registrations. Bidders complete the online form, pay a non-refundable registration fee by ACH debit ($40.00 for the 2024 sale), and file an electronic W-9 so the Treasurer can issue an accurate 1099-INT. The 2024 registration window opened Monday, May 20 and closed at 11:59 p.m. Thursday, June 13, four days before the sale. Bidders must be 18 or older on the sale date. An entity bidder needs 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 Fremont County Recorder. Registration and auction-site help is available at (877) 243-9997 or support@iowataxauction.com.

  3. 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.

  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

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

  • The Treasurer's mailing address is 506 Filmore St., PO Box 299, Sidney, IA 51652. The sale itself is conducted from the Treasurer's office on the first floor of the Fremont County Courthouse at 501 Filmore, Sidney.
  • Office hours are 8:00 a.m. to 4:30 p.m., Monday through Friday. Treasurer: Alise Snyder.
  • The delinquent tax list is published around the first week of June in the Tabor Beacon. Parcels on that published list are also posted on the auction site and the county website before the sale, though auction-site data requires a completed bidder registration.
  • Delinquent notices go out to owners in May, ahead of the June sale.
  • Beginning June 1 the Treasurer requires guaranteed funds for delinquent taxes and accepts no personal checks or eChecks online.
  • The county posts a non-redeemed county-held certificates list, most recently generated 5/22/25, covering certificates dating back to 2004 that the county still holds. That list is separate from the annual sale list.
  • Certificate holders may pay subsequent delinquent taxes starting the 15th of October and the 15th of April.
  • iowatreasurers.org shows a different office phone, (712) 374-2344. The county's own Treasurer page and the Treasurer's letterhead both give (712) 374-2122, so use that number and treat the other as a secondary line.

Iowa rules

Max interest rate
24% per year, fixed by statute (not bid down)
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.
Governing statute
Iowa Code Chapter 446

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.
