Indiana tax sales: what you are really bidding on

Two kinds of county auction get lumped together in northern Indiana, and confusing them is an expensive mistake. A sheriff’s sale sells a house after a lender forecloses a mortgage. A tax sale sells something much smaller: a certificate that gives you a lien on a parcel whose owner stopped paying property taxes, a clock the owner can stop by paying, and — only if that clock runs out and you follow a strict notice procedure — the right to ask a court for a deed. This guide covers the tax side in St. Joseph, Elkhart, LaPorte, Marshall and Kosciusko counties. Mortgage foreclosures have their own guide on sheriff’s sales.

Tax sale or sheriff’s sale: the difference in one table

A sheriff’s sale is a way to buy a house; a tax sale is mostly a way to earn a statutory return on a delinquent owner’s taxes. For a house, the foreclosure buyer’s guide is the better starting point.

How a parcel ends up on the list

Under Indiana Code 6-1.1-24-1, the county treasurer certifies a list of real property to the auditor each year, no later than 51 days after the first tax due date. A parcel qualifies when taxes from the prior year’s spring installment or earlier are still delinquent and the unpaid total exceeds $25 (how the bills work). The auditor mails the owner notice at least 21 days before the county asks the circuit court for a judgment and order for sale, and an owner who pays in full before the auction takes the parcel off the block.

Every parcel carries a minimum bid set by statute: the delinquent taxes and special assessments, the current year’s taxes whether or not they are late yet, the penalties, and the county’s costs of the sale. The flat postage and publication charge varies by county — St. Joseph County’s 2026 notice listed $80, Elkhart County’s listed $55.

The annual tax sale: what the winning bid buys

The treasurer sells each parcel to the highest bidder at public auction, subject to the right of redemption, and the law lets counties run the auction online. Both of the largest Michiana counties do: St. Joseph County’s 2026 sale ran online on September 1 and 2, and Elkhart County’s was scheduled online for October 1, 2026. The winning bidder pays the treasurer immediately. Money bid above the minimum goes into a tax sale surplus fund, which the owner of record can later claim.

What you walk away with is a certificate of sale, not a key. The owner still owns the house, can keep living in it, and can end your interest at any point in the redemption period by paying the county.

Redemption: the owner’s one-year window

For a parcel sold at the regular tax sale, the redemption period is one year after the date of sale (IC 6-1.1-25-4). St. Joseph County’s 2026 notice put the expiration at September 2, 2027; Elkhart County’s at October 1, 2027. To redeem, the owner pays the county, and the county pays the bidder, under a formula in IC 6-1.1-25-2:

• 110% of the minimum bid if redeemed within six months of the sale, or 115% after six months;
• the overbid — the amount paid above the minimum — plus 5% a year on it;
• any later taxes the bidder paid, plus 5% a year;
• certain title-search and notice costs the bidder incurred and certified to the auditor.

That formula is the whole investment case. One exception matters: parcels on the county’s vacant and abandoned property list are sold in a separate phase of the sale, and the statute gives them no right of redemption at all.

The commissioners’ certificate sale

Parcels that draw no bid at the minimum do not simply vanish. The county commissioners acquire a lien for the minimum bid, and the redemption period on those parcels is only 120 days from the date the county takes the lien — St. Joseph County’s notice said that period may run out December 31, 2026. The commissioners may then offer those certificates at a separate public sale, for less than the original minimum bid, after publishing notice once a week for three weeks with the last notice at least 30 days ahead (IC 6-1.1-24-6.1). A certificate bought there carries a 120-day redemption period from the date of that sale.

These are the main auction’s leftovers — some overlooked small lots, others parcels whose problems earlier bidders already found.

From certificate to deed: the notice trail

If nobody redeems, the certificate holder still owns nothing. The deed depends on a sequence of steps:

1. First notice. Within six months after a regular tax sale — or within 90 days after a commissioners’ certificate sale — the buyer sends notice by certified mail, return receipt requested, to the owner of record and to anyone with a substantial property interest of public record, such as a mortgage lender (IC 6-1.1-25-4.5).
2. The petition. After redemption expires, and no later than three months after, the buyer files a verified petition in the court that entered the sale judgment, asking it to direct the auditor to issue a tax deed. Notice goes out again, and anyone with an interest has 30 days to object (IC 6-1.1-25-4.6).
3. The deed. Within 150 days after the hearing that grants the petition, the buyer files the court order and a sales disclosure form with the auditor, pays the recording fees, and pays any outstanding taxes — or the auditor cannot issue the deed.

What a tax deed gives you — and what it does not

A properly issued tax deed vests title in fee simple, free of liens created before or after the sale, with two statutory exceptions: liens that federal law gives priority, and taxes that accrue after the sale. It remains subject to recorded easements, covenants and deed restrictions, and to zoning and building rules. A tax deed is prima facie evidence of a valid sale, but it can still be challenged, and Indiana law provides a quiet-title action for that reason. Before bidding real money, ask a title company what it will require before it insures a title that came through a tax deed.

The risks the list does not print

You bid blind. There is no interior inspection and no seller’s disclosure — Indiana’s disclosure statute expressly excludes transfers made because the owner failed to pay taxes. The address may be wrong. St. Joseph County’s notice states that the county does not warrant the street address or common description. Occupants stay put. The deed notices are not required for people in possession who are not shown in the public records, so a tenant can still be there when the deed issues, and removing anyone is a court process. Environmental problems are real. The statute lets a county decline to take a deed where cleanup would exceed the property’s value. Your money is tied up for as long as the full year.

How to find your county’s tax sale list

Start with the county treasurer and auditor. St. Joseph County posts a Tax Sale Notice page with the current advertisement and links to its online auction and full property list; Elkhart County posts its notice on the county website and notes that later notices appear there rather than in print. LaPorte, Marshall and Kosciusko counties publish through their auditor and treasurer offices. Two lists help early: the auditor must make the delinquent-fall-installment list available to cities and towns or on the county website at least 106 days before applying for judgment, and must post the list of liens the county holds within 30 days after the tax sale. Dates, costs and platforms change from year to year, so confirm every deadline with the county before you register.

When buying direct beats bidding

If the goal is a house, the tax list is still useful — as a list of owners under pressure, some of whom would rather sell, pay the delinquency and keep their equity. That is an ordinary purchase with an inspection, a title policy and a price checked against the monthly market report (South Bend’s median sale price was $190K through June 2026) and the MichianaRealty.com™ pages for Elkhart, LaPorte and Warsaw. The buy-direct playbook covers approaching owners and making an offer covers the paperwork; for bare land, read the rural-property guide first.

Frequently asked questions

How does the Indiana tax sale work?

Each year the county treasurer certifies parcels with delinquent property taxes, the county obtains a court judgment, and the treasurer auctions each parcel to the highest bidder at or above a minimum bid covering the taxes, penalties and costs. The winner receives a certificate of sale — a lien subject to the owner’s right to redeem — not the property.

How long is the redemption period after an Indiana tax sale?

For a parcel sold at the regular county tax sale, the owner has one year after the date of sale to redeem. Parcels struck to the county because nobody bid, and certificates later sold at a commissioners’ certificate sale, carry a 120-day redemption period. Parcels on the county’s vacant and abandoned property list have no right of redemption.

What is a commissioners’ certificate sale in Indiana?

It is the follow-up auction for parcels that drew no bid at the regular tax sale. The county commissioners hold a lien on those parcels and may sell the certificates to the public for less than the original minimum bid after publishing notice. Those certificates carry a 120-day redemption period.

Do you get the house at an Indiana tax sale?

Not at the auction. You get a certificate. If the owner redeems, you are paid back with the statutory premium and interest. If nobody redeems, you must have sent the required notices and then petition the court within three months after redemption expires; only then does the auditor issue a tax deed.
