How Johnson 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
The county's own notice to purchasers states: "The annual tax sale is usually held by the Johnson County Treasurer on the third Monday in June at 8:00 a.m., and for each succeeding day, for as long as purchasers are present or until all parcels have been sold. The adjourned annual sale is then to the following month according to the date shown on the calendar." The 2026 sale was set for Monday, June 15, 2026 at 8 a.m.
Registration and deposit

Bidders must pre-register in person in the tax division of the Treasurer's office before the sale. The bidder registration form states: "Participants must pre-register at the Treasurer's office by 5:00 pm, June 5th" for the June 15 sale, and a single registration covers the annual sale plus subsequent adjournments. The fee is $58.00 per bidder number (tax identification number). Registration also requires a completed and signed federal W-9. Bidders who are not individuals must have a designation of agent for service of process on file with the Iowa Secretary of State, or a verified statement meeting the requirements of Iowa Code chapter 547 on file with the Johnson County Recorder. Certificates and tax sale deeds are issued in the exact name shown on the registration and W-9. A bidder may designate an appointee to bid in their absence through written notice to the Treasurer.

Sale format and venue
Johnson County holds its tax sale in person, not online. No online bidding platform is used, so plan to attend or send an appointee. The sale takes place at the Johnson County Administration Building, 913 S. Dubuque Street, Iowa City, in Conference Room 110 (the Betty Sass Conference Room). Bidding follows Iowa's bid-down-ownership method run by an auctioneer: every parcel opens at 100 percent, the auctioneer pauses for active bidders to bid downward in whole percentages from 99 percent to 1 percent, and when bidding stops or reaches 1 percent the winner is drawn by random selection. The selected bidder has a few seconds to say "SOLD" to take the certificate or "PASS", in which case another bidder is drawn. Payment is due in full at the end of the sale by personal check or money order; two-party checks and cash are not accepted. Certificates can take up to 15 days to arrive while staff post records. The Treasurer issues a 1099-INT at year end. For parcels bought at the regular tax sale, the 90-day notice of right of redemption may be issued after one year and nine months from the sale date; for parcels bought at the public bidder tax sale, that notice may be issued after nine months. The office publishes the delinquent list as a newspaper publication proof (the 2026 list ran as a Gazette proof of Johnson County delinquent taxes). Verify the current year's date, deadline and room with the Treasurer's tax department before making plans, since the county posts a fresh notice and registration form each spring.

Johnson County tax sale list and auction calendar

For Johnson 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 Tax Sale Publication Lists 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. The auction platform is still being verified. Confirm the next sale date and registration window with the county before you bid.

  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 Johnson County

  1. Start with the live sale list

    Pull the current advertised parcels from Tax Sale Publication Lists. Lists can change before the sale, so recheck the county source before you price a parcel.

  2. Confirm registration and deposit

    Bidders must pre-register in person in the tax division of the Treasurer's office before the sale. The bidder registration form states: "Participants must pre-register at the Treasurer's office by 5:00 pm, June 5th" for the June 15 sale, and a single registration covers the annual sale plus subsequent adjournments. The fee is $58.00 per bidder number (tax identification number). Registration also requires a completed and signed federal W-9. Bidders who are not individuals must have a designation of agent for service of process on file with the Iowa Secretary of State, or a verified statement meeting the requirements of Iowa Code chapter 547 on file with the Johnson County Recorder. Certificates and tax sale deeds are issued in the exact name shown on the registration and W-9. A bidder may designate an appointee to bid in their absence through written notice to the Treasurer.

  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.

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.
