Iowa — Tax & Mortgage Foreclosure

Legal information, not legal advice. Verify against the cited primary sources before acting. Last verified: 2026-06-01.

Reader orientation (Iowa is unusual): Iowa is a tax-lien-certificate → tax-deed state with a bid-down-ownership-percentage auction. The certificate holder pays only the delinquent taxes, interest, fees and costs (Iowa Code §446.7, §446.16) and, if the owner never redeems, takes a treasurer’s deed to the entire parcel — there is no public cash auction that generates excess bid proceeds. As a result Iowa has no tax-sale surplus/“overplus” statute; the equity above the tax debt is simply captured by the deed holder. That captured equity is exactly what is now under tyler-v-hennepin-county attack in Iowa (see Modules 0, 3, 8). Do not import “surplus-recovery-agent” assumptions from deed-sale states like Florida or Georgia.

0. Identity & Classification

  • Recording unit: county (count: 99)
  • Tax sale type: tax lien certificate (“certificate of purchase”) maturing into a tax deed — Iowa Code §446.29 (certificate of purchase), §448.1 (deed)
  • Tax foreclosure process: administrative (no court action; treasurer conducts the annual public sale and issues the deed after the statutory redemption-expiration notice) — Iowa Code §446.7, §447.9, §448.1
  • Mortgage foreclosure process: both — judicial is the default (Iowa Code ch. 654); a limited non-judicial track exists for non-agricultural, non-owner-occupied property (Iowa Code ch. 655A)
  • Selling authority: county treasurer (tax sales) — Iowa Code §446.7; sheriff (mortgage execution sales) — ch. 654/626
  • Statutory home: Title X, Subtitle 2 — Iowa Code ch. 446 Tax Sales, ch. 447 Tax Redemption, ch. 448 Tax Deeds
  • Tyler v. Hennepin compliance: non_compliant (challenged, unresolved) — Iowa’s tax-deed scheme lets the certificate holder keep the owner’s entire equity for only the tax debt, with no statutory mechanism to return surplus. That is the precise harm condemned in tyler-v-hennepin-county. A 2026 suit (Woods v. Fayette County / Equity Trust) directly challenges it; reform bill SF 2313 (2026) to distribute “overplus” did not pass. See Axios Des Moines (2026-05-18).

1. Tax Sale Mechanics

  • What is sold: a certificate of purchase (tax lien); the delinquent tax lien transfers with the certificate and expires when the certificate expires — Iowa Code §446.29, §446.16(3).
  • Bidding method: bid-down ownership percentage. “The person who offers to pay the total amount due … for the smallest percentage of the parcel is the purchaser,” and that designated percentage becomes an undivided interest on issuance of the treasurer’s deed; the designated percentage “shall not be less than one percent.” Ties are broken by random selection — Iowa Code §446.16(1).
  • Interest / penalty: redemption carries interest of two percent (2%) per month, “counting each fraction of a month as an entire month,” from the month of sale — Iowa Code §447.1(1). (Effective ~24% simple annual yield to the certificate holder; statutory, not bid.)
  • Minimum bid composition: the total amount due — delinquent taxes + interest + fees + costs — for which the parcel is liable; the parcel is offered “for the total amount due” — Iowa Code §446.7(1), §446.15.
  • Sale frequency / typical month: annual, on the third Monday in June — Iowa Code §446.7(1). May be adjourned at ≤2-month intervals until parcels sell — §446.25.
  • “Public bidder” sale: parcels offered ≥1 year and remaining unsold are offered at a “public bidder sale” (shorter 9-month notice path) — Iowa Code §446.18.
  • Venue / platform: predominantly online; common vendor iowataxauction.com (operated for many counties); some counties use other platforms — see Des Moines County 2025 tax-sale rules. Platform choice is a county fact (see treasurer-sale / county pages).
  • Registration / deposit: treasurer may charge a reasonable registration fee (not against a county/municipality); only persons defined in §4.1 may bid; non-individuals need a federal TIN and a designated agent for service or a ch. 547 statement on file — Iowa Code §446.16(2),(4). W-9 and online registration are typical — Des Moines County rules.
  • Subsequent taxes (“subs”): the certificate holder may pay later-year delinquencies beginning one month and 14 days after an installment becomes delinquent; subs earn the same 2%/month added to the redemption amount, and must be recorded by 5:00 p.m. on the last business day of the month to accrue that month’s interest — Iowa Code §446.32, §447.1(1).

2. Right of Redemption → see right-of-redemption

  • Pre-deed right: a parcel “may be redeemed at any time before the right of redemption expires,” by paying the treasurer the amount for which the parcel was sold + the certificate fee + 2%/month interest + subsequent-year taxes (with the same interest) + recoverable costs — Iowa Code §447.1(1).
  • Post-sale period / runs-from: the redemption right does not automatically end on a fixed clock; it ends 90 days after completed service of the statutory notice of expiration of right of redemption, which the certificate holder may not serve until:
    • 1 year 9 months after a regular sale (so a regular sale’s practical floor is ~21 months + 90 days);
    • 9 months after a §446.18 public-bidder sale;
    • 3 months after a §446.19A/446.19B county/city housing or public-nuisance sale. — Iowa Code §447.9(1), §447.12.
  • Tolling / when the clock truly stops: service is “complete only after an affidavit has been filed” with the treasurer; the 90 days runs from completed service, and redemption must be received by the treasurer on or before the 90th day (next business day if it falls on a weekend/holiday) — Iowa Code §447.12.
  • Who may redeem: the owner of record / person in whose name the parcel is taxed; persons in possession (incl. tenants — see dohrn-v-mooring-2008); mortgagees, vendors under recorded contract, lessees, and any party of record who must be served; assignees of those rights; and a county for owner-occupied residential parcels (county right of redemption) — Iowa Code §447.1, §447.9(2),(3).
  • Redemption amount formula: sale price + certificate fee + 2%/month from month of sale + each subsequent tax payment with 2%/month from its month of payment + authorized costs (certified-mail, publication, record search ≤ $300) — Iowa Code §447.1, §447.13.
  • Premium to certificate holder: none beyond statutory interest; Iowa is a fixed-rate (not bid-down-interest) state — the “premium” is the bid-down equity capture (see Module 0/3).
  • Procedure: pay the treasurer (or via the treasurer’s authorized internet site) before the deadline; treasurer issues a certificate of redemption — Iowa Code §447.5.
  • Extinguishment: the right is extinguished by completed 90-day notice + no redemption, whereupon the treasurer issues the deed — Iowa Code §447.12, §448.1.
  • Special tolling: persons with a legal disability may redeem (and, post-deed, sue in equity to redeem) up to one year after the disability is removed, subject to the §448.15/448.16 affidavit bar and a 3-year outer limit — Iowa Code §447.7. After the deed, redemption is by equitable action only — §447.8. Federal-law tolling (e.g., SCRA, bankruptcy) operates on top of these — see bankruptcy-automatic-stay.

3. Surplus / Excess Proceeds → see surplus-funds, third-party-recovery-rules

  • Belongs to: No tax-sale surplus exists by design. Because the buyer pays only the total amount due (taxes/interest/fees/costs) and then takes the whole parcel by deed, the tax-sale process produces no excess cash to distribute — there is no claim waterfall, no filing venue, and no claim deadline in chapters 446–448. The owner’s equity above the tax debt is forfeited to the deed holder. Iowa Code ch. 446, 448 (no surplus provision).
  • Tyler exposure: this is the constitutional fault line. Under tyler-v-hennepin-county (598 U.S. 631 (2023)), retaining equity above the debt is an unconstitutional taking. Iowa’s scheme has not been reformed: SF 2313 (2026), which would have created an “overplus” distribution process, failed; Woods v. Fayette County / Equity Trust (2026) is litigating the takings claim — Axios (2026-05-18). Status: non_compliant / unresolved.
  • Mortgage-sale surplus (different track): a sheriff’s mortgage execution sale can yield excess proceeds; “if the amount paid to the clerk is in excess of the prior bid and liens, the clerk shall refund the excess to the party paying the amount,” or credit junior liens per affidavit — Iowa Code §628.20. (See Module 4.)
  • Escheat / where stray funds land: general unclaimed-property law (treasurer of state) governs abandoned funds, including any mortgage-sale or redemption-overpayment funds left unclaimed — Iowa Code ch. 556.
  • Third-party recovery (finder/locator): for any unclaimed funds reported under ch. 556, recovery-agent agreements are governed by Iowa Code §556.11(10):
    • fee cap: 15% of recoverable property;
    • timing / cooling-off: agreements made within 24 months of the date funds were payable/delivered are unenforceable; only agreements after 24 months are valid;
    • contract rules: must be in writing, signed by the owner, and disclose the nature/value of the property and the name/address of the holder;
    • licensing: the locator must be licensed as a private investigation business under chapter 80A to collect a fee;
    • prohibited: collecting a fee while unlicensed; charging on excessive or unjust consideration (challengeable any time); the cap/timing do not bind a bona fide attorney fee contract (ch. 602, art. 10). — Iowa Code §556.11(10). Note: because tax sales generate no surplus, there is no tax-surplus-recovery market in Iowa; the 556.11 finder rules reach unclaimed cash funds, not lost tax-deed equity.
  • Assignment of claim allowed? A certificate of purchase is assignable (Iowa Code §446.31), but a certificate may not be assigned to a person not entitled to redeem (§446.31(3)). No surplus “claim” exists to assign in the tax context.
  • Notice to former owner required? Yes — the 90-day notice of expiration of right of redemption must be served on the owner/occupant and recorded-interest parties (see Modules 2 & 6).

4. Mortgage Foreclosure

  • Process: both. Default is judicial foreclosure (Iowa Code ch. 654); a non-judicial option exists only for non-agricultural, non-owner-occupied property and bars a deficiency judgment (Iowa Code ch. 655A).
  • Sale officer: sheriff (judicial execution sale).
  • Redemption after sale (default): one year from the day of sale, with the debtor entitled to possession; the debtor’s right is exclusive for the first 6 months, and creditors may redeem from each other through 9 months — Iowa Code §628.3, §628.5, §628.15.
  • Shortened redemption (if the mortgagee waives deficiency / per mortgage terms): parcels < 10 acres may be reduced to 6 months (or 3 months if non-agricultural) by agreement in the mortgage where the mortgagee waives deficiency — Iowa Code §628.26; abandoned property may drop to 60 days — §628.27; non-ag / non-residence property may be 180 days, reducible to 90/30 days — §628.28.
  • Foreclosure without redemption: the plaintiff may elect foreclosure without redemption under Iowa Code §654.20; ch. 628 then does not apply (§628.1A), and the borrower may instead seek a court-ordered delay of sale (commonly up to 6 months; less if deficiency waived/abandoned) — [needs_verification: exact §654.20 delay periods not re-read from primary text].
  • Reinstatement right: [needs_verification: a specific statutory pre-acceleration reinstatement section was not located in the retrieved primary text — ch. 654/535B not re-read].
  • Deficiency judgment: allowed in judicial foreclosure with redemption; barred where the plaintiff elects no-redemption foreclosure (§654.20) and barred in involuntary non-judicial foreclosure (ch. 655A). [needs_verification: precise §654.6/§615.x deficiency and fair-value-offset mechanics not re-read from primary text].
  • Surplus distribution (mortgage sale): excess over bid and liens is refunded to the party who paid, or credited to junior liens per filed affidavit — Iowa Code §628.20.

5. Sale Procedure Playbooks

Treasurer (tax-lien) sale — ordered steps → see treasurer-sale

  1. Treasurer mails notice of sale to the taxpayer by regular mail within 15 days of the sale (§446.2) and serves the §446.9 annual-tax-sale notice by first-class mail by May 1 (with mailed notice to recorded mortgagees/vendors/lessees who filed a request) — §446.9(1),(3).
  2. Publish the sale once in an official newspaper 1–3 weeks before the sale (§446.9(2)); if publication can’t be procured, post in the treasurer’s office for 2 weeks (§446.11).
  3. Sell on the third Monday in June, each parcel offered separately for the total amount due, by bid-down ownership % with random tie-break — §446.7, §446.15, §446.16.
  4. Buyer pays immediately; treasurer issues a certificate of purchase — §446.23, §446.29.
  5. After the waiting period, certificate holder serves the 90-day notice of expiration of right of redemption by both regular and certified mail on owner/occupant and recorded parties, then files the affidavit of service — §447.9, §447.12.
  6. If unredeemed, treasurer executes and records the tax deed within ~90 days of completed service — §448.1.

Sheriff (mortgage) sale — ordered steps → see sheriff-sale

  1. Lender files judicial foreclosure (ch. 654); court enters decree and orders special execution.
  2. Sheriff publishes/posts notice of sale and conducts the public auction; surplus over bid/liens refunded per §628.20.
  3. Redemption period (typically 1 year; reducible — Module 4) runs; debtor keeps possession.
  4. If unredeemed, sheriff’s deed issues. [needs_verification: exact ch. 654 notice/publication-week counts not re-read from primary text].
  • Notice requirements (tax sale): publication once, 1–3 weeks pre-sale; mailing by May 1 + within-15-days post-sale + the dual-mail 90-day expiration notice; posting as substituted service — Iowa Code §446.2, §446.9, §446.11, §447.9.
  • Upset bid / confirmation: none for the tax-lien sale (administrative; no judicial confirmation). The functional analog is the 90-day redemption-expiration window. (Mortgage sheriff sales are subject to court processes, not upset bids.)
  • Payment terms (tax sale): immediate payment of the total bid; failure re-offers the parcel — Iowa Code §446.23.
  • Deed issued: treasurer’s tax deed; conveys “all the right, title, interest, and estate of the former owner,” subject to restrictive covenants, certain prior-conveyance interests, and post-sale tax-sale certificate holders’ rights — Iowa Code §448.3(1). Not a warranty deed.

6. Due Process & Notice → see due-process-notice

  • Standard: Mullane “notice reasonably calculated, under all the circumstances, to apprise interested parties.” Iowa requires the §447.9 expiration notice by both regular and certified mail; the Iowa Supreme Court held this satisfies due process and that personal service is not required — kluender-v-plum-grove-2023.
  • Required attempts: mailed §446.9 annual notice + publication; then dual-mail (regular + certified) 90-day expiration notice on owner, person in possession, and all recorded-interest parties (mortgagee, contract vendor, lessee) — Iowa Code §447.9(1),(2); publication substitute if mail service can’t be made — §447.10. Under jones-v-flowers, returned mail obligates additional reasonable steps where practicable.
  • Consequence of defective notice: void. If a record owner / taxed party is not served the §447.9 notice, the treasurer’s deed is void (subject to the §448.15/448.16 affidavit-bar process) — Iowa Code §448.3(2); see dohrn-v-mooring-2008 (tenants in possession must be served; unserved → deed void, redemption stays open). Sales made in violation of ch. 446 by the treasurer are void — §446.27(3); fraud voids the sale — §448.9.
  • Leading cases: kluender-v-plum-grove-2023, dohrn-v-mooring-2008, tyler-v-hennepin-county, jones-v-flowers, mennonite-v-adams.

7. Title & Marketability

  • Deed warranty level: statutory treasurer’s tax deed (no warranties); presumptive evidence of the facts in §448.4 and conclusive evidence of the facts in §448.5 (regularity of listing/levy/notice/sale; grantee is the purchaser).
  • Marketable immediately? No, not practically. Title is encumbered by the redemption-disability window, the 3-year challenge SOL, and lender/title-company caution toward tax titles; quiet title or the §448.15 affidavit process is usually needed before resale/insuring.
  • Quiet title required? Commonly yes in practice; alternatively the tax-title holder may file the §448.15 affidavit after taking possession, which triggers a 120-day window for adverse claimants to file (and 60 days thereafter to sue); if none, tax title is conclusively established and adverse claims are barred — Iowa Code §448.15, §448.16.
  • SOL to challenge the deed: an action to challenge under §447.8 or §448.6, or to recover the parcel, “shall not be brought after three years from the execution and recording” of the deed — Iowa Code §448.12. The deed may be challenged only by an equitable action in district court — §448.6(1).
  • Title insurance availability: Iowa uses the Iowa Title Guaranty program (in lieu of conventional title insurance); coverage of tax titles is fact-dependent and typically requires the §448.15 process or quiet title — [needs_verification: no primary Iowa Title Guaranty underwriting standard for tax deeds was retrieved].
  • Common defects: defective/omitted §447.9 service (void deed — dohrn-v-mooring-2008); undivided-percentage deeds (<100%) creating co-tenancy with the former owner (Iowa Code §446.16(1), §448.15(3)); legal-disability redemption rights (§447.7); surviving senior interests excepted by §448.3(1).

Surplus topic tag: covered by tyler-v-hennepin-county (the controlling surplus/takings authority binding on Iowa, now in active Iowa litigation). A purely Iowa-court surplus holding does not yet exist; see Module 11 open_questions for the pending Woods v. Fayette County matter.

9. Edge Cases (state-specific notes)

  • bankruptcy-automatic-stay — A bankruptcy filing stays issuance of a tax deed; Iowa expressly tolls the affidavit/cancellation clock: where filing is “stayed by operation of law,” the §447.12 affidavit deadline extends to the later of 6 months after the stay is lifted or 3 years from the sale — Iowa Code §446.37.
  • federal-tax-lien-redemption — A federal tax lien gets the IRS a 120-day post-sale redemption right under 26 U.S.C. §7425; the IRS is a “party of record” entitled to §447.9 notice — [needs_verification: no Iowa-specific primary source on IRS §7425 redemption from an Iowa tax deed was retrieved].
  • heirs-property — Heirs/successors are “persons entitled to redeem”; an assignment of a redemption right by an heir is recognized (§446.31 charges a $10 assignment fee “in the case of an assignment by an estate”) — Iowa Code §446.31(1), §447.7.
  • Persons with a legal disability — extended redemption up to 1 year after disability removed, with a 3-year outer bar tied to the deed — Iowa Code §447.7.
  • Undivided-percentage tax title — because bidding is bid-down %, a deed can convey < 100%, leaving the former owner as co-tenant on the remainder; the §448.15 affidavit form expressly contemplates “an undivided ___ percent interest” — Iowa Code §446.16(1), §448.15(3).
  • Government / municipal parcels — parcels owned by the state or its subdivisions, or already held on a county/municipal tax certificate, are not offered, and such a tax sale is “void from its inception” — Iowa Code §446.7(2).
  • Abandoned / public-nuisance & “county-as-purchaser” — counties/cities may buy and assign certificates for abandoned residential / vacant parcels (housing rehab) and public-nuisance parcels, with shortened 3-month redemption-notice paths — Iowa Code §446.19A, §446.19B, §447.9(1).
  • manufactured-homes — [needs_verification: Iowa’s treatment of manufactured-home tax delinquency (ch. 435) not retrieved as primary text].

10. Operations

  • Where records live: county treasurer (tax sale list, certificates, redemption, subs payments — Iowa Code §446.24 “record of sales” in the county system); county recorder (recorded tax deeds, §448.15 affidavits/claims — §448.17); clerk of district court (mortgage foreclosure decrees, sheriff’s sales, redemption deposits — ch. 628); Treasurer of State (unclaimed property — ch. 556).
  • Public portals: statutes at legis.iowa.gov; statewide tax-sale auction platform iowataxauction.com; county treasurer / iowataxandtags.org consolidated info; unclaimed property via the Iowa Treasurer of State.
  • Typical costs & timelines: investor outlay = total taxes due + interest/fees; yield = 2%/month (~24%/yr) until redemption; regular-sale path to deed ≈ ~22+ months (1 yr 9 mo wait + 90-day notice); public-bidder ≈ ~12 months; county housing/nuisance ≈ ~6 months. Record-search costs added to redemption capped at $300 — Iowa Code §447.1, §447.9, §447.13.
  • Key agencies: County Treasurer (selling authority); County Recorder; Clerk of District Court; Iowa Treasurer of State (unclaimed property); Iowa Title Guaranty.
  • Useful forms: Certificate of purchase (§446.29); Certificate of publication form (§446.12); Notice of expiration of right of redemption (§447.9); Affidavit of service (§447.12); Treasurer’s deed form (§448.2); §448.15 tax-title affidavit (§448.15).
