Woodbury County tax sales, Iowa

Verified

Woodbury County runs its sale online through GovEase and states that the 2026 sale was not a live tax sale. Registration was online only from May 18 to June 10, cost a non-refundable $43 paid through GovEase, and required an online W-9 and the GovEase payment form. Pre-bids were required, uploaded from June 11 at 8:00 a.m. until 8:00 a.m. on June 15, before the 9:00 a.m. auction. The Treasurer web page gives the sale window as 9:00 a.m. to 10:30 a.m. Each parcel opened at a 100 percent interest and bid down by whole points, with random selection on a tie. The classic mistakes are missing the pre-bid deadline, treating research as optional when the county places it on the investor, and missing the 4:00 p.m. payment deadline on sale day.

Selling office: Woodbury County Treasurer, Tina M. Bertrand, 822 Douglas St, Room 102, Sioux City, IA 51101, Phone: 712-279-6495 (Property Tax)

Next sale: Monday, June 15, 2026 annual tax sale (held). The Woodbury County Terms and Conditions of Tax Sale (2026) state the 2026 annual Tax Sale will be held online by the Woodbury County Treasurer at 822 Douglas St., Room 102 in Sioux City on Monday, June 15, 2026, with the auction beginning at 9:00 a.m. and all bids submitted online at www.Govease.com. The Treasurer Tax Sale page states the same June 15, 2026 date and gives the online event window as 9:00 a.m. to 10:30 a.m. A total parcel count and a total sold count for the 2026 sale are NOT PUBLISHED in the county sources read; the county posts a parcel listing, not totals.

As of November 9, 2026, the Woodbury County Treasurer Tax Sale page states the Annual Tax Sale takes place the 3rd Monday in June each year, and the 2026 terms publish adjourned sale dates through April 19, 2027. A dated June 2027 annual sale is NOT PUBLISHED in the county sources read.

Research Woodbury County parcels before you bid

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across Woodbury County, searchable by address, owner, or county, including parcels that never reach a sale list.

How Iowa tax sales work

• Iowa holds one sale a year, on the third Monday in June, and the county treasurer runs it. Under Iowa Code section 446.7 the treasurer offers every parcel on which taxes are delinquent, for the total amount of taxes, interest, fees and costs due. The notice discipline is statutory: the treasurer mails notice of the date, time and place to the person in whose name the parcel is taxed not later than May 1, and publishes it once in at least one official county newspaper at least one week and not more than three weeks before sale day (section 446.9). In 2026 the sale day was Monday, June 15, 2026. A different June date is allowed for good cause, which is one reason each county's own published date governs over the statewide pattern.
• The bid is a percentage of the parcel, not a price and not an interest rate. Bidders offer to pay the total amount due in exchange for a percentage of the parcel; the smallest percentage wins, the designated percentage may not be less than 1 percent, and an equal smallest bid is resolved by a random selection process run by the treasurer (section 446.16). The winner then pays the full total amount bid immediately, or the parcel is offered again (section 446.23). The percentage matters only later: if a deed issues, it conveys the undivided interest the percentage represents. A room full of buyers all pay the same dollars for a parcel; the auction decides how much of the parcel those dollars buy.
• The certificate earns a fixed statutory rate that nobody bids. The purchaser receives a certificate of purchase (section 446.29). When the owner redeems, the redemption price includes interest of 2 percent per month on the amount for which the parcel was sold, counting each fraction of a month as an entire month, and the same rate on any subsequent taxes the purchaser paid (section 447.1). Summaries that describe Iowa bidding as an interest rate auction are importing another state's system: in Iowa the rate is set by the statute, the same for every certificate in every county, and the only competitive variable is the percentage.
• Redemption stays open until the holder closes it, and owners use the whole window. The owner may redeem at any time before the right of redemption expires by paying the treasurer the amount sold for, the certificate fee, the 2 percent per month interest, and subsequent taxes with interest (section 447.1). Parcels leave the published list as owners pay, right up to the sale, and certificates are redeemed at the treasurer's office, not by paying the holder. The certificate is an interest-bearing claim with a deed at the end of a long fuse, not a purchase of the land on sale day.
• The fuse is one year and nine months, and the 90 days run from completed service, not from the notice. After one year and nine months from the date of a regular sale, the holder may cause a notice of expiration of the right of redemption to be served by both regular mail and certified mail on the person in possession, the person in whose name the parcel is taxed, and lienholders and other persons with an interest of record (section 447.9). Service is not complete until the affidavit of service, with the costs of service, is filed with the treasurer (section 447.12), and only then does the 90 day clock run; redemption must reach the treasurer, or the treasurer's authorized internet site, before the close of business on the ninetieth day. A holder who counts the 90 days from the mailing has started the clock early and can lose the deed over it.
• The deed follows immediately when the 90 days expire. On return of the certificate and payment of the deed and recording fees, the treasurer makes out, signs, acknowledges and records the deed before delivering it (sections 448.1 and 448.3), and the recorded deed vests the purchaser with the right, title, interest and estate of the state, the county and the former owner, as to the percentage the bid designated. Challenges are narrow: an equitable action in district court (section 448.6), a bar on actions brought more than three years after execution and recording (section 448.12), and a faster bar where the holder records the affidavit described in section 448.15, after which a claim must be filed within 120 days and suit brought within 60 days after that (sections 448.15 and 448.16). The two year recital in the deed form in section 448.2 is form language, not a waiting rule.
• The clocks are not uniform, and this is the correction that matters most on publicly held paper. The one year nine month wait belongs to the regular sale. A certificate sold at a public bidder sale under section 446.18 carries a nine month wait before the expiration notice may be served. Certificates arising from a housing purchase under section 446.19A or a public nuisance tax sale under section 446.19B carry a three month wait (section 447.9). Applying the regular sale clock to a public bidder certificate overstates the wait by a full year, and to a housing or nuisance certificate by a year and a half. Which sale produced the certificate is printed on the county's own records and decides the deed timeline before any other fact does.
• Parcels nobody bids on do not disappear, and Iowa law never calls what happens next a scavenger sale. Parcels previously advertised and offered for one year or more that remain unsold for want of bidders are offered at a public bidder sale on the day of the regular sale or an adjournment of it (section 446.18). If no bid is received there, or the bid is less than the total amount due, the county, through its treasurer, must bid the full total amount due and take the certificate without paying money, the taxing bodies being charged their shares (section 446.19); a city may bid to protect its own interests but is not the default holder. The word scavenger appears nowhere in chapters 446, 447 or 448. Certificates are assignable by endorsement and entry in the county system at the treasurer's office for a 100 dollar transaction fee, 10 dollars for an assignment by an estate or by a county, and may not be assigned to a person entitled to redeem the parcel other than a municipality (section 446.31).
• Registration is partly statutory and partly county terms, and the counties do not run the same sale. The statute authorizes a reasonable registration fee capped in total at the cost of the sale and limits who may register, bid or own a certificate, with a federal tax identification number and either a secretary of state agent designation or a chapter 547 verified statement required of non-individuals (section 446.16). Windows, payment forms and the platform are not in the statute at all. In the 2026 sales in this set, Polk and Woodbury Counties sold online only through GovEase with pre-bids, Dubuque and Story Counties took online bids only through Iowa Tax Auction inside a single morning, Linn County ran its sale at the Treasurer's Office with bids online, and Scott, Black Hawk and Johnson Counties sold fully in person, Johnson by oral bidding. Read the county's own packet for the year in front of you; there is no statewide Iowa registration window, deposit rule or platform.

How buying works in Woodbury County

Registration was online only at www.Govease.com. No mailed, emailed or in person registrations were accepted. Registration began at 12:01 a.m. on Monday, May 18, 2026 and closed at 11:59 p.m. on Wednesday, June 10, 2026. Bidders paid a non-refundable $43.00 registration fee through Govease.com, completed an online W-9 form, completed the Govease Payment Instructions and Disclaimer Form, and uploaded a Certificate of Existence from the Iowa Secretary of State or a Trade Name Verification Statement from the Woodbury County Recorder where applicable. All bidders had to be 18 years of age or older as of June 15, 2026. Pre-bids were required, uploaded beginning at 8:00 a.m. on June 11, 2026 through 8:00 a.m. on June 15, 2026, and bids were not accepted after that 8:00 a.m. deadline.

• Everyone pays the same dollars; the bid only sizes the share. The total amount due is fixed by the tax record, and the winning bidder pays all of it for the smallest percentage offered. The underwriting question is therefore double: is this parcel worth the full amount due as an interest bearing claim, and is the percentage you would have to bid to win it a share you would accept as a deed. A 1 percent win on a researched parcel is a deed to a sliver.
• Payment is due at the gavel, in the county's form. Section 446.23 makes the purchase money immediate. The online counties settle through their platforms, in person counties take the instruments their packets name, and Johnson County in 2026 took personal checks and money orders only, at the end of the sale. A bidder funded a day late is a spectator.
• The interest rate rewards patience, not aggression. Two percent per month is fixed under section 447.1 and cannot be bid away. The certificate's economics turn on redemption likelihood and the deed clock the certificate carries, regular sale paper at one year nine months or public bidder paper at nine months, not on anything that happens in the bidding.
• Registration closes before the sale opens, differently in every county. Fees, windows and identity rules vary: paper registration with original signatures in Black Hawk County, online only registration in the platform counties, one bidder number per tax identification number in Scott County. The buyers who miss Iowa sales miss the registration deadline, not the bidding.

Terms: what a bid actually costs

What happens to parcels that do not sell in Woodbury County

Woodbury County publishes adjourned tax sales on August 17, 2026, October 19, 2026, December 14, 2026, February 15, 2027 and April 19, 2027, with bidders registered by 4:00 p.m. on the Friday prior to the scheduled adjourned sale date if there are parcels available for sale. The Treasurer Tax Sale page posts a Public Bidder Parcel Listing as of July 8, 2026 and an Adjourned Tax Sale Parcel Listing as of July 8, 2026. It defines public bidder parcels as parcels advertised two years on the tax sale where Woodbury County holds the tax certificate, with interested buyers directed to call the Board of Supervisors office at 712-279-6525, and adjourned tax sale parcels as parcels that did not have the taxes paid by any investors on the last Tax Sale, with interested buyers directed to contact the Treasurer's Office at 712-279-6495.

Before you bid

• Read the county's own 2026 or current year packet before anything statewide. The statute sets the frame; the county's tax sale packet sets the platform, the registration window, the fee, the payment forms and the sale hours, and the counties in this set split between two online platforms and in person rooms. The packet is the sale.
• Ask which sale produced any certificate you are offered secondhand. The deed clock is nine months or three months on public bidder, housing and nuisance paper, against one year nine months on regular sale paper. An assignment priced off the wrong clock misprices the wait by a year or more.
• Re-verify the parcel against the final list. Owners pay and parcels are pulled up to sale day, and lists published weeks ahead shrink. The treasurer's final published list for the sale is the only list worth a funded registration fee.
• Set the maximum before the sale opens. The free Max-Bid Calculator below works backwards from your exit value. In Iowa run it twice: once for the claim at full amount due with 2 percent per month interest, and once for the deed outcome at the percentage you realistically have to bid to win.
