Indiana tax sales are a complex but potentially lucrative way to invest in real estate or earn a high interest rate on your money. The process is strictly governed by state law, which favors the original property owner through a lengthy "redemption period" before an investor can actually take title to the property. 1. Two Main Types of Sales
Counties generally hold two different types of auctions depending on how long the taxes have been delinquent:
Treasurer’s Tax Sale (Standard): Held typically in the Fall for properties with at least one year of delinquent taxes. Bidding starts at the amount of unpaid taxes and costs.
Commissioner’s Sale (Secondary): These involve properties that didn't sell at the Treasurer's sale. They often happen in the Spring (e.g., Lake County has one scheduled for May 4–8, 2026) and may have significantly lower starting bids, sometimes as low as $500. 2. The Redemption Period & Returns
When you win a bid, you do not immediately own the property. Instead, you receive a tax sale certificate (a lien). The original owner has a chance to "redeem" the property by paying you back with interest. Redemption Period Initial Interest (Penalty) Treasurer's Sale 10% (first 6 months) / 15% (after 6 months) Commissioner's Sale 10% (first 6 months)
Surplus Interest: If you bid more than the minimum amount, you typically earn a lower interest rate (historically around 5% per annum) on that "overbid" amount.
Recoverable Costs: If the owner redeems, you can also be reimbursed for attorney fees, title searches, and any subsequent taxes you paid, provided you file the correct paperwork (like Form 137B) with the county auditor. 3. Path to Ownership (The Tax Deed) indiana tax sales top

Indiana’s tax sale system offers a compelling "top" opportunity for investors to acquire property at below-market rates or earn double-digit interest. However, the process is unforgiving: failure to navigate the one-year redemption, perfect notice, or understand surplus funds can turn a profit into a loss. For property owners, the system is punitive but navigable—redemption is almost always the best financial decision. Ultimately, success in Indiana tax sales belongs not to the highest bidder, but to the most procedurally disciplined.
