What Happens at a Tax Lien Auction? A Complete Guide for Homeowners
Published by AuctionBlock.org — a mission-driven company dedicated to foreclosure prevention education
If your county has notified you that your property will be included in a tax lien auction, or if you have heard the term and want to understand what it means, this guide explains the entire process from start to finish.
Tax Lien Auctions vs. Tax Deed Auctions
First, it is important to understand the difference between the two main types of tax sales in the United States.
Tax Lien Auction: The county sells the debt (the unpaid tax lien) to an investor. The investor pays the county what you owe in taxes, and in return, the investor receives a certificate giving them a legal claim on your property. You still own your home, but you now owe the investor instead of the county — and the investor earns interest on that debt.
Tax Deed Auction: The county sells the property itself. The winning bidder receives the deed to your home. You lose ownership.
About 30 states use the tax lien system, about 20 use the tax deed system, and some use a hybrid. Your state’s specific system is listed in our 50-state foreclosure law database.
What Leads to a Tax Lien Auction?
A property ends up at a tax lien auction after the homeowner has failed to pay property taxes for a period of time, typically one to three years. Before the auction happens, the county must provide the homeowner with notice, although the specific notice requirements vary by state.
The typical sequence is:
- Property taxes become delinquent
- County sends delinquency notices
- Penalties and interest accrue
- County publishes notice of upcoming tax sale (often in local newspaper and online)
- County sends direct notice to the homeowner
- Tax lien auction takes place
How the Auction Works
Before the Auction
Counties publish a list of all properties with tax liens being auctioned. This list typically includes the property address, the owner’s name, the amount of delinquent taxes, and the parcel number. These lists are often published in local newspapers, on county websites, and through third-party tax sale listing services.
Investors research the properties and decide which liens they want to bid on.
During the Auction
Tax lien auctions can be held in person at the county courthouse or online. The process varies by state, but there are two common bidding formats:
Bid-Down-the-Interest-Rate: Investors bid on the interest rate they will accept. The county sets a maximum interest rate (for example, 18%), and investors compete by bidding lower rates. The investor who accepts the lowest interest rate wins the lien. This is better for the homeowner because it reduces the cost of redemption.
Premium Bidding: Investors bid the amount they are willing to pay above the lien amount. The highest bidder wins but only receives the lien amount plus interest when the homeowner redeems. The premium is often not refunded. This format is common when properties have significant equity.
Rotational Bidding: In some counties, liens are assigned to investors in rotation to ensure fair distribution.
After the Auction
The winning investor receives a tax lien certificate. This certificate does not give them ownership of the property. It gives them the right to collect the delinquent taxes plus interest from the homeowner.
What This Means for the Homeowner
If your tax lien was sold at auction, here is what changes:
- You still own your home. The investor does not own your property.
- You now owe the investor. Instead of owing the county, you owe the investor who purchased your lien.
- Interest is accruing. The interest rate on the lien may be high — as much as 18% to 36% per year in some states.
- You have a redemption period. State law gives you a specific window of time to pay off the lien and clear the debt. This period ranges from six months to three years depending on your state.
- If you do not redeem, you can lose your home. After the redemption period expires, the investor can begin foreclosure proceedings to take ownership of your property.
The Redemption Process
To redeem your property, you must pay the full amount of the tax lien plus all accrued interest and any fees. You pay this to the county, which then pays the investor.
Important details:
- The redemption amount grows over time due to interest
- Some states allow partial redemption; others require full payment
- The county clerk or treasurer’s office can provide your exact redemption amount
- You may be able to set up a payment plan — ask your county
How to Protect Yourself
Before the Auction
If your property is scheduled for a tax lien auction, you may still be able to prevent the sale by:
- Paying the delinquent taxes in full
- Setting up a payment plan with the county
- Applying for property tax exemptions or assistance programs
- Filing for bankruptcy (which triggers an automatic stay)
After the Auction
If your lien has already been sold:
- Pay attention to all notices. The investor must notify you before they can foreclose.
- Know your redemption deadline. This is the most important date in the entire process.
- Seek free help immediately. Contact AuctionBlock.org for free counseling.
- Do not fall for scams. Investors and scammers may contact you offering to "help" in exchange for your deed. Never sign over ownership of your home.
Surplus Equity After Tyler v. Hennepin County
In 2023, the U.S. Supreme Court ruled in Tyler v. Hennepin County that governments cannot keep surplus proceeds from tax sales beyond the amount of taxes owed. If your home is sold at a tax sale for more than you owe in taxes, penalties, and fees, you are entitled to the surplus.
However, many homeowners do not know they are owed surplus funds, and the process for claiming them varies by state. If your property was sold at a tax sale, check with your county to determine whether surplus funds are available.
