You can buy a house by paying back taxes in one of two ways: negotiate directly with an owner who has fallen behind and build the tax debt into a reduced purchase price, or bid at a government tax sale where the property or the tax debt is being auctioned because of the delinquency. Both routes typically land you below market value. Both carry risks that the discount is paying you to accept, and treating them as the same transaction is where most buyers lose money.
The leverage behind either approach comes from one legal fact: a local property tax lien outranks almost every other claim against a home, including mortgages recorded years earlier and even federal tax liens filed by the IRS.1Office of the Law Revision Counsel. 26 USC 6323 – Validity and Priority Against Certain Persons An owner who cannot pay has little time and few options, and a buyer who can solve the tax problem is solving the one problem that scares off conventional buyers and their lenders.
Buying Directly From a Delinquent Owner
The cleaner path is a negotiated purchase from the current owner, with the back taxes folded into the deal. The owner wants out from under the debt. You want the discount. The negotiation turns on who physically pays the taxing authority and how that payment is reflected in the price.
Structuring the Price
Two arrangements dominate. In a seller credit, the seller reduces the purchase price by the amount of the delinquent taxes and the buyer pays the taxing authority at closing. In a direct assumption, the buyer takes on the tax debt and the purchase price drops accordingly. The total cash leaving your pocket is the same either way: price to the seller plus arrears to the government.
Your purchase agreement has to spell out the mechanics. It should reference the exact payoff amount from the collector’s statement, name the party responsible for payment, and require the closing agent to pay the taxing authority directly before any proceeds reach the seller. Vague language here is how closings fall apart.
Using Escrow to Keep the Payoff Safe
An escrow account held by the title company is the safest mechanism. The funds earmarked for the tax arrears sit in escrow until the title company confirms the transaction is ready to close. The escrow agent then pays the taxing authority, and the lien release is recorded in the public records. That simultaneous close-and-pay sequence prevents the scenario where money gets diverted and the lien stays on the property.
The title company’s commitment to insure must list the tax lien as an exception that will be removed at closing. That commitment is the insurer’s promise to issue a clean policy once the lien is released. Without it, you own a property no future buyer or lender will take without repeating the whole exercise.
Financing a Purchase With a Tax Lien in Place
Conventional lenders will not fund a loan on a property with an outstanding tax lien, because the lien would sit ahead of their mortgage and defeat their first-lien position. The workable approach is a synchronized closing: the title company pulls the payoff statement, the lender funds the loan, and the closing agent routes the tax payment to the collector before releasing anything else. The title insurer issues the lender’s policy once it has confirmation the lien release has been or will be recorded.2Internal Revenue Service. Understanding a Federal Tax Lien
If the tax debt is large relative to the home’s value, or the seller has no equity cushion, traditional financing may not work at all. Hard money and private lenders are more tolerant of title defects and close faster, with the trade being much higher rates and short terms.
Buying at a Government Tax Sale
When delinquency crosses a statutory threshold, the local government auctions either the tax debt or the property itself. You are buying from the government, usually with no warranties and limited information about what claims might survive.
Tax Lien Certificate Sales
In roughly half of U.S. states, the government sells the debt rather than the property. You pay the delinquent taxes and receive a certificate entitling you to collect the debt plus statutory interest from the owner. Rates vary widely by state, generally from about 8 percent to 24 percent annually, with a few states authorizing rates as high as 36 percent.
If the owner redeems within the statutory window, you get your money back with interest but no property. If the owner never redeems, you can eventually petition to foreclose on the certificate and take ownership. The wait before you can even start foreclosure is often two to three years, and the legal process adds more time after that.
Tax Deed Sales
In a tax deed sale, the government has already foreclosed and is selling the property outright. The winning bidder receives a deed, typically a limited warranty deed or a special commissioner’s deed rather than the full warranty deed used in ordinary sales. That difference will matter later when you refinance or resell.
Even with the deed in hand, the former owner may still have the right to reclaim the property. Most states grant a statutory redemption period after a tax sale, ranging from none at all to as long as four years. During that window, the former owner can pay the purchase price plus penalties and interest to recover the home. Your ownership is provisional until the clock runs out.
What a Tax Sale Actually Requires
Bank financing is effectively unavailable for tax sale purchases. Lenders will not underwrite a mortgage on a property with a clouded title or an active redemption period. You need cash or private capital for the bid, with reserves on top of that for clearing title, making the property habitable, and carrying it through any redemption window.
Properties sold at tax auctions are sold as-is, often after years of vacancy. Inspection access may be limited to a drive-by, with no interior walkthrough before you bid. Price what you cannot see as risk, not as upside.
Due Diligence Before You Commit Any Money
A professional title search is non-negotiable on either path. The search reveals every recorded claim: the tax lien, special assessments like utility district fees, and any other liens from creditors. Buyers who skip this step tend to discover after closing that they inherited problems much larger than the back taxes.
Get an Exact Payoff Figure
Ask the local tax assessor or collector for a formal payoff statement. The amount owed is never just the original tax. It includes accrued interest, annual penalties, and administrative fees that can add 20 to 40 percent on top of the base debt depending on how long the taxes have been unpaid. The statement is good as of a specific date and typically expires within 30 to 60 days because interest keeps running.
Look Specifically for Federal Tax Liens
The title search has to check for a Notice of Federal Tax Lien. If the IRS filed a lien against the owner under 26 USC 6321, that lien attaches to all of the owner’s property, including the house.3Office of the Law Revision Counsel. 26 USC 6321 – Lien for Taxes Federal tax liens follow different rules than local property tax liens and do not automatically go away when the local tax debt is paid.
Inspect the House
A homeowner who could not pay the taxes probably could not pay the roofer either. Get a full inspection before finalizing a negotiated purchase. For auction properties, factor the lack of inspection access into your bid.
The Federal Tax Lien Trap at Tax Sales
This is where tax sale buyers most often get hurt. A federal tax lien can survive a tax sale and stay attached to the property, even after the local tax lien is wiped out. Whether that happens depends on whether the taxing authority gave the IRS proper notice before the sale.
Under 26 USC 7425, a nonjudicial tax sale discharges a federal tax lien only if the IRS received written notice by registered or certified mail at least 25 days before the sale.4Office of the Law Revision Counsel. 26 USC 7425 – Discharge of Liens If notice was not sent, or was sent late, the sale proceeds without disturbing the federal lien, and you end up owning the property subject to the IRS claim.5Internal Revenue Service. Federal Tax Liens
Even when notice is given correctly and the federal lien is discharged, the IRS keeps a separate right to redeem the property. The government has 120 days from the sale date, or the full state redemption period, whichever is longer, to pay you the purchase price and take the property.4Office of the Law Revision Counsel. 26 USC 7425 – Discharge of Liens The IRS rarely exercises this right, but when it does, you get your bid back and nothing else. No reimbursement for repairs, carrying costs, or your time.
Before bidding, check county records for a Notice of Federal Tax Lien against the property or the former owner. If one exists, confirm the taxing authority followed the 25-day notice procedure. If you cannot verify that notice was given, treat the federal lien as surviving the sale and bid accordingly, or walk away.
Clearing Title With a Quiet Title Action
A tax deed does not automatically give you marketable title. Most title insurers will refuse to issue a policy on a tax sale property until the title has been judicially cleared. The standard tool is a quiet title action, a lawsuit asking the court to extinguish competing claims and declare you the rightful owner.
You start by identifying every party with a potential claim: the former owner, mortgage holders, lien holders, anyone with a recorded interest. You file a complaint in the county where the property sits and serve each identified party. If no one contests, the court enters default judgment and your title is clean. If someone does contest, the case goes to trial.
Uncontested actions usually resolve in three to six months. Contested ones can stretch past a year, especially when former owners or heirs are hard to locate and notice has to be published. Legal fees run from a few thousand dollars to $15,000 or more for complex cases. Budget this cost into your acquisition from the start.
How the Back Taxes You Pay Are Treated by the IRS
Paying a seller’s delinquent property taxes does not give you a deduction. The IRS treats those payments as part of your cost of acquiring the property. You add the amount to your basis instead of deducting it.6Internal Revenue Service. Publication 530 – Tax Information for Homeowners
The reasoning is that those taxes were the seller’s obligation, so paying them is effectively paying part of the purchase price. The higher basis reduces your taxable gain when you eventually sell, but there is no immediate write-off.
Current-year property taxes work differently. The IRS splits the tax year between buyer and seller based on the closing date, regardless of when the taxes are actually due locally. You deduct only your share, covering the portion of the year after you took ownership. The seller’s share belongs to the seller even if you wrote the check.6Internal Revenue Service. Publication 530 – Tax Information for Homeowners
Surplus Proceeds Belong to the Former Owner
When a property sells at a tax auction for more than the debt that triggered the sale, the excess is called surplus proceeds. Some jurisdictions used to keep it. In 2023, the U.S. Supreme Court held unanimously in Tyler v. Hennepin County that a government’s retention of surplus beyond the tax debt owed is a taking under the Fifth Amendment.7Supreme Court of the United States. Tyler v. Hennepin County, Minnesota
For buyers, two things follow. Auction prices may rise in some markets as jurisdictions restructure their sales to comply, because the former owner now has a constitutional claim on any excess. And if your winning bid exceeds the debt, the surplus goes to the former owner or their creditors, not back to you. Procedures vary, but the constitutional floor is settled: the government cannot keep more than it is owed.
