In Texas, a property tax lien attaches to your real estate automatically on January 1 of each year, before any bill arrives, and it secures every dollar of tax, penalty, and interest that will come due for that year. If you don’t pay by January 31, the account goes delinquent on February 1 and charges start piling on. Left unresolved, the lien gives your county the legal power to sue, take the property through a court-ordered auction, and sell it to the highest bidder. Texas law does give former owners a chance to buy back a foreclosed property, but the price climbs the longer they wait. Here is how each stage of the process actually works.
When the Lien Attaches and Why It Beats Your Mortgage
Under Texas Tax Code Section 32.01, a lien for property taxes attaches to real property on January 1 of each year, automatically and without any action by the taxing unit. It secures the base tax plus every penalty and interest charge that will later be imposed for that year, and it exists before the county even mails a bill.1State of Texas. Tax Code Chapter 32 – Tax Liens and Personal Liability
That lien outranks almost every other claim on the property. A mortgage recorded years earlier, a home equity loan, a private judgment lien: all of them fall behind the taxing unit. In any foreclosure or dispute over sale proceeds, the government gets paid first. The Legislature built that priority in because property taxes fund schools, roads, and emergency services.
What You Owe Once the Taxes Go Delinquent
Property tax bills go out in the fall, and the balance is due by January 31 of the following year. Anything unpaid on February 1 becomes delinquent, and statutory penalties and interest begin accumulating right away.2Texas Comptroller. Property Tax Law Deadlines
The penalty starts at six percent of the unpaid tax in February and grows by one percentage point each month. Interest runs separately at one percent per month with no cap. On July 1, the penalty jumps to a flat twelve percent no matter how many months have passed.3State of Texas. Tax Code 33.01 – Penalties and Interest Month by month, the combined charges look like this:
- February: 6% penalty + 1% interest = 7% added to the base tax
- March: 7% penalty + 2% interest = 9%
- April: 8% penalty + 3% interest = 11%
- May: 9% penalty + 4% interest = 13%
- June: 10% penalty + 5% interest = 15%
- July 1: 12% penalty + 6% interest = 18%, plus a collection penalty of up to 20% if the account has been referred to an attorney
The July 1 collection penalty is where the damage accelerates. Once the taxing unit turns the account over to a law firm, the additional charge of up to twenty percent gets tacked onto the full balance to cover legal costs. Interest keeps running at one percent per month indefinitely, so a debt that started as a routine tax bill can grow past a third larger within the first year.2Texas Comptroller.

Ways to Stop Collection Before Foreclosure
Two provisions in the Tax Code can pause collection while you sort things out. Most owners in trouble don’t know about them.
The first is an installment agreement under Section 33.02. If you owe delinquent taxes, you can ask your local tax office to split the balance into monthly or quarterly payments. The plan has to cover the full debt including penalties and interest, and if you default, the taxing unit can immediately pursue the entire remaining balance. For an owner with steady income but no lump sum, it keeps foreclosure on hold.
The second is a tax deferral under Section 33.06 for homeowners who are sixty-five or older or who are disabled. Filing a deferral affidavit with the county tax office postpones all collection activity on your residence homestead for as long as you own and occupy the property. Penalties and interest still accrue during the deferral, but no lawsuit or auction can move forward. The deferred taxes come due when you sell, move out, or pass away. For older Texans on fixed incomes, this is often the single most important protection on the books.
The Lawsuit and the Auction
When the debt cannot be resolved through payment or deferral, the taxing unit files suit in district court to foreclose the lien. The petition lays out the property, every party with a recorded interest (including your mortgage lender), and the total owed broken down by tax year. Every recorded interest holder must receive notice of the case. Once the court is satisfied that notice was proper and the taxes are genuinely owed, it enters a judgment authorizing sale.
Tax foreclosure auctions in Texas take place on the first Tuesday of the month, typically at the county courthouse or through an authorized online bidding platform.4Williamson County, TX. Tax Sales A sheriff or constable runs the sale after the court issues an order of sale.
Each property has a minimum bid. For most properties, the minimum is the lesser of the appraised market value or the total judgment amount (delinquent taxes, penalties, interest, and court costs combined). Homesteads get different treatment: the minimum is the greater of those two figures, which makes it harder for someone’s home to sell at a deep discount. If no bidder meets the minimum, the taxing unit can take the property in and hold it for a later resale.
The winning bidder receives a sheriff’s deed to whatever interest the former owner had. Sale proceeds are applied first to the tax debt, then to other lienholders in order of priority. Anything left over belongs to the former owner, but that money doesn’t arrive automatically. You have to file a claim for the excess proceeds, and waiting too long can mean forfeiting them.
Buying the Property Back: Right of Redemption
Texas law gives former owners a window to redeem property sold at a tax auction. How long you have depends on what kind of property it was.
- Homesteads and agricultural land: two years from the date the purchaser’s deed is recorded.
- Everything else (vacant lots, commercial buildings, non-homestead residential): 180 days from the deed recording date.
Redemption is expensive. You must reimburse the purchaser for the full auction price, any taxes or insurance the purchaser paid on the property after the sale, and the deed recording costs. On top of that, you owe a redemption premium set by statute:
- Homestead redeemed during the first year: 25% premium on the purchase price.
- Homestead redeemed during the second year: 50% premium.
- Non-homestead property within the 180-day window: 25% premium.
A successful redemption voids the purchaser’s deed and returns ownership to you. The premium is the cost of getting the property back; skipping it means losing it for good.
Aftermath: Credit and Federal Tax Consequences
A completed foreclosure stays on your credit report for seven years from the sale date.5Consumer Financial Protection Bureau. If I Lose My Home to Foreclosure, Can I Ever Buy a Home Again? Fannie Mae imposes a seven-year waiting period after a foreclosure before a borrower qualifies for a conventional mortgage, with a possible reduction to three years if extenuating circumstances can be documented.6Fannie Mae. Significant Derogatory Credit Events – Waiting Periods and Re-establishing Credit
The IRS treats a foreclosure sale as a disposition of property. You are considered to have sold the property at auction, and the difference between the amount realized and your adjusted basis produces a taxable gain or a deductible loss. If the property was your personal residence or an investment asset, the gain is typically capital.7Internal Revenue Service. Publication 4681 – Canceled Debts, Foreclosures, Repossessions, and Abandonments You may receive a Form 1099-A reporting the acquisition of the property, or a 1099-C if any debt was canceled in connection with the sale.8Internal Revenue Service. Instructions for Forms 1099-A and 1099-C Talking to a tax professional in the year of the sale is worth the cost.
What If You Also Owe Federal Taxes
An existing federal tax lien does not push ahead of your Texas property tax lien. The IRS recognizes that state and local property tax liens based on the value of real property hold a “superpriority” over federal tax liens, covering both general property taxes and special assessments for public improvements. Even when the IRS has a recorded lien against you, the county’s claim for unpaid property taxes gets paid first.9Internal Revenue Service. Federal Tax Liens That superpriority does not extend to personal property taxes, state income taxes, or franchise taxes, which follow the ordinary first-in-time rule.
Using Bankruptcy to Pause an Auction
Filing bankruptcy triggers an automatic stay that immediately halts most collection activity, including a pending tax foreclosure sale. The stay kicks in the moment the petition is filed, and the taxing unit cannot proceed with the auction until it asks the bankruptcy court for permission to lift the stay.10United States Bankruptcy Court Central District of California. Automatic Stay: 362: Relief: Real Property; Foreclosure
Bankruptcy does not wipe out the property tax debt. In Chapter 13, the debtor proposes a three-to-five-year repayment plan, and property taxes secured by a lien must be paid in full through that plan. For a homeowner with income but no lump sum, that structure can stop the bleeding and save the house. Chapter 7 provides the same automatic stay but no repayment mechanism, so the taxing unit will typically move to lift the stay and continue with foreclosure. Bankruptcy is a heavy step with its own credit consequences, but for someone facing an auction next Tuesday, it can buy the time needed to arrange a payment plan or file a deferral affidavit.
