How Tax Delinquent Property Sales Work in Iowa
Iowa is a tax-lien state. Each county treasurer holds an annual tax sale on the third Monday of June, where investors buy a tax-sale certificate on parcels with delinquent taxes. The certificate is a lien, not ownership; it earns 2% per month — 24% per year — on the amount paid until the owner redeems. Iowa uses a distinctive bid-down mechanic: bidding opens at a 100% undivided interest in the parcel, and investors bid down the percentage of the property they would accept if it ever goes to deed, to a floor of 1%. When several bidders tie at the smallest percentage, the winner is chosen by a random drawing. If the owner never redeems, the certificate holder can eventually obtain a tax deed — but only for the undivided percentage bid, so returns come mainly from redemption interest rather than from taking whole parcels. Counties run their sales through the Iowa Tax Auction Program (Zeus Auction), GovEase, or in person.
Bidding & Auctions
Iowa uses a bid-down-ownership format rather than premium or interest bidding. Bidding opens at a 100% undivided interest in the parcel, and investors compete by accepting a smaller and smaller percentage of the property they would take if it ever goes to a tax deed — down to a 1% minimum. Whoever accepts the lowest percentage wins; when multiple bidders tie at the smallest percentage, the winner is chosen by a random drawing. The interest rate is fixed by statute at 2% per month, so it is never bid down. Registration ahead of the sale and a deposit are typically required.
Redemption & Penalties
The effective redemption window is roughly two years. The certificate earns 2% per month (24% per year) from the month of sale, and any subsequent taxes the holder pays accrue at the same rate. After one year and nine months from the sale, the holder may serve a 90-day notice of expiration of the right of redemption; the owner then has 90 days from completed service to pay. Redemption is made through the county treasurer for the certificate amount plus accrued interest, subsequent taxes, and the holder's costs. Critically, if the holder fails to serve that notice within three years of the sale, the certificate is cancelled and the investment is forfeited.
See Iowa Code Chapters 446, 447, and 448. Specific procedures vary by county — always verify with the local tax assessor/collector before bidding.

When is the Iowa tax sale?▾
Each county holds its annual tax sale on the third Monday of June. Adjourned sales may continue afterward for parcels that did not sell on the sale date.
How much interest does an Iowa tax certificate earn?▾
2% per month — 24% per year — calculated from the month of sale. This is among the highest statutory rates in the country, and subsequently-paid taxes accrue at the same 2% per month.
What does "bidding down the percentage" mean in Iowa?▾
Instead of bidding the price up, investors bid down the undivided percentage of the property they would accept if it ever goes to deed, to a floor of 1%. Ties at the lowest percentage are broken by a random drawing, so most returns come from redemption interest, not from taking whole parcels.
How long until I can get a tax deed in Iowa?▾
After one year and nine months you may serve a 90-day notice of expiration; the owner then has 90 days to redeem, after which a deed can issue. Miss the three-year deadline to serve that notice and your certificate is cancelled.
