If a property doesn't sell in the fall, it often moves to a in the spring.

Many counties sell certificates to the bidder who offers the lowest interest rate (a "reverse auction"). However, some of the top Indiana counties (like Marion County/Indianapolis) use a premium bidding system where you bid up the purchase price.

Never bid on a property sight unseen just because the price looks good.

Investors also earn a 5% per annum interest rate on any "overage"—the amount bid and paid above the minimum tax delinquency.

If you want to land a property, you cannot just show up with a checkbook. Follow this exact process.

Planning your investment calendar around county sales is essential. Below are key dates for major counties in 2025.

Some counties publish their tax sale lists two to three months before the sale and update them weekly. For example, Hamilton County updates its tax sale list by noon each Friday during the two months preceding the sale. Monroe County’s certified list is available after July 1. Always check the county treasurer’s website or the official auction platform for the most current information.

To reach the top of the investor pool, you must employ a disciplined strategy before, during, and after the auction. 1. Master County-Specific Rules

Bidding starts at the amount of unpaid taxes owed on the property, plus penalties, costs, and any current‑year taxes. The Indiana Code sets a minimum sales price for each property, generally based on the total amount owed. While the property must be sold to the highest bidder at public auction, the minimum bid ensures the county recovers its delinquent taxes. Indiana also uses a premium bid process: investors earn 10% on the lien amount and 5% on any amount bid above the lien. The premium interest rate has been subject to change, but it still makes excess bids profitable.

Indiana tax sales are with no warranty. Two "top" pitfalls:

You paid $10,000 for a certificate in July. The owner redeems in December (5 months). They owe you $10,000 + ($10,000 * 0.15 * 5/12) = $10,625. That is a 6.25% return in five months.

Not all tax liens are created equal. Avoid properties that are:
