Registration and deposit

Bidders register online through the Iowa Tax Auction platform. The treasurer's page says, "If you would like to register to bid at the Jasper County Tax Sale, please use the link below," and links to iowataxauction.com. The platform's own steps are to create an account, apply to the auction, view listings, bid, and then view results. Jasper County does not publish a registration fee, deposit amount, or registration cutoff on its site, so confirm those with the treasurer's office before the June sale.

The treasurer's office runs the sale under Iowa Code chapter 446 and describes it as "an open competitive bidding process" over parcels whose taxes have become delinquent. Jasper County does not post the parcel list as a downloadable file. The page says delinquent parcels subject to sale are advertised in June in the Newton Daily News, that copies are available at the treasurer's office, and that printouts may be purchased. Parcels are "listed in parcel number order and have a sequence number for bidding purposes." The county also states that "The investor is responsible for all research on parcels available for auction." For redemption fund questions the page directs callers to the treasurer's office at 641-792-7731. The treasurer's office moved to the Jasper County Administration Building at 315 W. 3rd St. N., Suite 500; the 101 1st St. N. courthouse address still appears in the site footer, so use the Administration Building address for in-person visits.

From lien to deed

Run by: County Treasurer
Frequency: none
Typical timing: Iowa holds no tax deed auction. The treasurer makes out a treasurer's deed to the certificate holder immediately after 90 days have expired from completed service of the notice of expiration of the right of redemption, once the holder returns the certificate and pays the deed and recording fees.

There is nothing for an investor to bid on at the deed stage in Iowa. The only auction is the June certificate sale. The certificate holder must return the certificate of purchase and remit the deed and recording fees within 90 calendar days after the redemption period expires, or the treasurer cancels the certificate.

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.

Notes for Jasper County

Jasper County sells tax sale certificates online through the Iowa Tax Auction platform, which runs on the Zeus Auction Program. There is no in-person courthouse auction described on the county's page.
The county does not publish the sale parcel list on its website. The list runs in the Newton Daily News in June, and the treasurer's office sells printouts at the counter, so plan research time around that publication date.
Registration fee, deposit, and cutoff date are not published by Jasper County. Confirm them with the treasurer's office or inside the Iowa Tax Auction account before the June sale.
Property tax counter hours are 8:00 a.m. to 4:30 p.m. Monday through Friday, plus the second Saturday of each month from 8:00 a.m. to 11:00 a.m.

Iowa statewide 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.
