How Montgomery County sells delinquent taxes

From lien to deed

Indiana holds no general public tax deed auction. Once the redemption period runs out, the certificate holder files a verified petition in the same court that entered the judgment of sale, and the court directs the county auditor to issue the deed. That petition must be filed no later than three months after the redemption period expires, or the purchaser's lien terminates. One narrow exception exists: real property a county, city, or town executive has certified as vacant or abandoned is auctioned separately, and there the county auditor deeds fee simple title straight to the highest bidder with no right of redemption.

When it runs
The Treasurer's Real Estate Tax Sale page states the sale "is usually scheduled during the month of October." The most recent published notice set the annual tax sale for October 07, 2025, "Beginning 10:00 AM Local Time," with properties commencing closing at 4:00 PM local time the same day and each parcel's specific closing time posted on the auction site.
Registration and deposit

Registration and bidding run entirely through the Zeus Auction site. Per the 2025 notice, you must first become a member of www.zeusauction.com, then register for the Montgomery County auction specifically. You must read, understand and agree to the rules of sale and payment terms, complete IRS Form W-9, and agree electronically to the registration statement described at IC 6-1.1-24-5.3(c). A business entity must provide a Certificate of Existence or Foreign Registration Statement under IC 5-23 from the Secretary of State to the Montgomery County Treasurer. For the 2025 sale the registration period opened at 8:00 AM local time on September 03, 2025 and closed at 12:00 PM local time on October 03, 2025; bidders who do not complete the full registration process are not approved to bid.

Sale format and venue
Montgomery County is an Indiana tax lien county. The Treasurer prepares the annual real estate tax sale and SRI Incorporated conducts it; the county page states "SRI is the company that conducts the sale. They advertise the properties on their website, www.SRIservices.com 30 days before the sale." The sale is an electronic auction conducted under IC 6-1.1-24-2(b)10 at www.zeusauction.com, so bidding is online rather than at the courthouse. Parcels three installments behind (a balance due from the spring of the prior year or earlier) become eligible, a certified letter goes to each listed taxpayer, the list is published in the local newspaper, and a $150 tax sale charge is added to each parcel. Bidding opens at the total owed on the parcel through the current year. Redemption is 110% of the minimum bid if redeemed within six months of sale or 115% if redeemed later, plus any surplus above the minimum bid with 5% per annum interest on that surplus; the 2025 notice set the redemption period expiry at October 07, 2026. The Montgomery County Auditor issues the sale certificate, and taking title or redeeming a parcel is handled in the Auditor's office at (765) 364-6400. Liens not sold at the annual sale move to a Commissioners' Certificate Sale, also online at www.zeusauction.com with reduced minimum bids; the most recent one was set for January 15, 2026 at 10:00 AM local time with registration closing at 4:00 PM local time on January 09, 2026. To pull a parcel from the sale, payment in cash or certified funds payable to the Montgomery County Treasurer had to reach 1580 Constitution Row, Suite B, Crawfordsville, IN 47933 by 12:00 PM local time on Friday, October 3, 2025. One caution: the Treasurer's page still carries older in-person language saying bidders "must register prior to the start of the sale" and that the "High bid must be paid in the Treasurer's office the day of the tax sale with certified funds," while the current statutory notice describes an online Zeus auction with an advance registration window. Confirm payment and registration mechanics with the Treasurer before bidding. The county also notes a tax sale property layer on its GIS site (Beacon by Schneider Corporation).

Montgomery County tax sale list and auction calendar

For Montgomery 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 SRI sale property search (county-designated property list) for the current advertised parcels, then recheck it before the auction.

  2. Register to bid

    Registration and bidding run entirely through the Zeus Auction site. Full requirements are in the sale card above.

  3. Sale day

    Bidding runs on ZEUS; check posted sale dates, registration status, and bidding windows there.

  4. Confirm with the office

    If the list, platform, and notice disagree, use Montgomery County Treasurer as the source to confirm which parcels are actually offered.

Before you bid in Montgomery County

  1. Start with the live sale list

    Pull the current advertised parcels from SRI sale property search (county-designated property list). Lists can change before the sale, so recheck the county source before you price a parcel.

  2. Confirm registration and deposit

    Registration and bidding run entirely through the Zeus Auction site. Per the 2025 notice, you must first become a member of www.zeusauction.com, then register for the Montgomery County auction specifically. You must read, understand and agree to the rules of sale and payment terms, complete IRS Form W-9, and agree electronically to the registration statement described at IC 6-1.1-24-5.3(c). A business entity must provide a Certificate of Existence or Foreign Registration Statement under IC 5-23 from the Secretary of State to the Montgomery County Treasurer. For the 2025 sale the registration period opened at 8:00 AM local time on September 03, 2025 and closed at 12:00 PM local time on October 03, 2025; bidders who do not complete the full registration process are not approved to bid.

  3. Check the state rules that change the bid

    Read the Indiana 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

Parcels that draw no bid at the treasurer's tax sale pass to the county executive, which acquires a lien for the minimum sale price and receives a tax sale certificate. The county executive may then adopt a resolution and offer those certificates at a separate advertised public sale, often called the commissioners' certificate sale, priced below the minimum bid that failed at the tax sale. Notice runs once a week for three consecutive weeks with the final advertisement at least 30 days before the sale. This is a scheduled sale rather than a walk-in list, and redemption on a certificate bought this way is 120 days. Check the county auditor page for the next commissioners' certificate sale date.

Indiana rules

Max interest rate
15% of the amount paid maximum, as a flat statutory penalty
Minimum return
10% statutory penalty at redemption
Redemption
The standard period is one year after the date of the treasurer's tax sale. Several tracks run 120 days instead: a certificate bought at the county executive's certificate sale, a lien the county executive holds that was never sold on, a sale to a purchasing agency qualified under IC 36-7-17 or IC 36-7-17.1, a certificate the county executive assigns to another political subdivision, and a parcel that was not offered at the tax sale at all. Property on the county auditor's vacant and abandoned list carries no right of redemption after its sale. A county treasurer may also extend redemption by agreement with the owner, in which case the extended period ends one year after the date of that agreement.
Surplus proceeds
The treasurer applies the payment first to the taxes, assessments, penalties, and costs in the minimum bid, then to other delinquent property taxes, then deposits the remainder in a tax sale surplus fund. The owner of record at the time the parcel was certified for sale, or the purchaser on a redemption, may file a verified claim against that fund. Unclaimed surplus transfers to the county general fund three years after it was received.
Governing statute
IC 6-1.1-24

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.
