If you’re looking at how to invest in tax liens in Texas, the first thing to know is that Texas doesn’t sell tax liens. It sells tax deeds. When property taxes go delinquent long enough, the taxing unit sues, wins a judgment, and the property itself is auctioned on the courthouse steps. The winning bidder walks away with a deed conveying the former owner’s ownership interest, subject to a limited right of redemption. Your return comes from one of two outcomes: the former owner buys the property back and pays you a 25% or 50% premium on top of what you bid, or the redemption window closes and you keep the property.1State of Texas. Tax Code Chapter 34 – Tax Sales and Redemption
That framing changes everything about how you approach the investment. You’re buying real estate, not a debt instrument, and every dollar of due diligence you’d apply to a normal property purchase applies here too.
What You’re Actually Buying
A Texas tax sale transfers ownership of real property. The deed you receive is a sheriff’s or constable’s deed conveying whatever interest the former owner held, cut through by the tax judgment. Most private liens are wiped out at the sale. A few obligations can survive, which is a separate problem discussed below.
If no one bids at least the minimum amount, the property is “struck off” to the taxing unit that requested the sale. That unit then owns the property and can resell it later through public or private sale. Struck-off properties sometimes offer better pricing because the taxing unit wants the parcel back on the tax rolls, but the resale terms and redemption rules can differ from the original auction. Read the specific offer carefully.
Researching Properties Before the Sale
Sale lists come out roughly 30 days before the auction. County Tax Assessor-Collectors publish them, and the law firms that represent taxing units in delinquent tax suits maintain searchable databases with the cause number, property address, and minimum bid for each parcel.
Every listing carries a legal description. Verify it against the county clerk’s real property records so you know exactly what you’re bidding on. A description that reads like a great deal can turn out to be an unbuildable strip, a landlocked lot, or a flood-prone parcel. Drive by whenever you can. Improvements sell as-is with no warranties, and you won’t see the interior before bidding.
Pull the court file for the underlying tax suit as well. Procedural defects in the foreclosure are the most common basis for a later attack on your title, and spotting them before you bid is cheaper than fighting them after.
Liens That Can Survive the Sale
Federal tax liens are the main hazard. Under federal law, the IRS must receive written notice at least 25 days before the sale, and even after a valid sale, the federal government retains a 120-day right to redeem the property by paying what you paid.2Office of the Law Revision Counsel. 26 U.S. Code 7425 – Discharge of Liens If the IRS wasn’t properly noticed, its lien can remain attached to the property after the sale. Municipal liens for health or safety code violations may also survive depending on the circumstances. A professional title search before you bid is the only reliable way to catch these.
If the property sits in an HOA, check whether outstanding assessments could follow you. Most Texas HOA governing documents give tax liens priority over assessment liens, so the tax sale usually extinguishes the HOA debt. Most, not all. Review the recorded restrictive covenants before you bid.
Registering to Bid
Texas law lets each county’s commissioners court require bidder registration before a tax sale. Where registration is required, you must register with the county assessor-collector before the sale begins.3State of Texas. Texas Code Tax 34.011 – Bidder Registration Registration requires your name, address, valid identification, and written authority if you’re bidding for someone else. You also sign a statement certifying that you owe no delinquent property taxes to the county or any taxing unit within it. The certification must be renewed at least annually.
Details vary by county. Some charge a small fee, and some require registration days or weeks in advance rather than the morning of the auction. Call the county assessor-collector’s office well ahead of the sale. Without valid registration where it’s required, the officer conducting the sale cannot accept your bid.
Auction Day
Tax sales in Texas happen on the first Tuesday of every month. They typically start at 10:00 a.m. on or near the county courthouse steps, though a growing number of counties now run online auctions through platforms like RealAuction.1State of Texas. Tax Code Chapter 34 – Tax Sales and Redemption For online sales, expect to register separately with both the platform and the county tax office.
Bidding opens at the minimum bid, which covers the total judgment: delinquent taxes, accrued penalties and interest, and the legal costs of the foreclosure suit. It’s open outcry, and the highest bid wins. Once you’re declared the winner, the full amount is due immediately, almost always in cash or cashier’s check within a few hours. Credit cards and personal checks generally won’t work. Have funds confirmed and ready before the first property is called.
After payment clears, the officer prepares the deed. Record it with the county clerk right away. Recording starts the clock on the redemption period and protects your interest against third-party claims. Recording fees follow a statutory structure that runs around $25 for the first page plus a few dollars per additional page, with slight county-by-county variation.
What You Can Do During the Redemption Period
Texas gives the tax deed purchaser something many other states do not: possession during the redemption window. The deed vests in you the former owner’s right to use and possess the property, even while their right of redemption is still open.4State of Texas. Tax Code 34.21 – Right of Redemption The former owner keeps only the right to buy the property back. They do not keep any right to occupy it, collect rent from it, or otherwise use it during that window.
Practically, you can take physical control of a vacant property, secure it, insure it, and rent it out. If the former owner or a tenant is still occupying the property and refuses to leave, you’d file a forcible detainer action in justice court, the same eviction process any landlord uses. The statute grants you the legal right to possession; it doesn’t hand you the keys.
The Redemption Window and What It Pays You
The former owner doesn’t permanently lose the property when the gavel falls. They get a window to reclaim it by paying you back with a premium. The length of the window and the size of the premium depend on the property type:4State of Texas. Tax Code 34.21 – Right of Redemption
- Homestead or agricultural land: two years from the date the deed is filed of record. Purchase price plus a 25% premium if the owner redeems within the first year, or 50% if they redeem during the second year.
- All other property: six months from the date the deed is filed of record. Purchase price plus a 25% premium.
Those premiums are your guaranteed return if the owner redeems. A 25% return in six months on a commercial parcel is what draws investors to this market. Redemption also means you give the property back, so any investment thesis has to work under both outcomes: the owner redeems and you collect the premium, or the owner doesn’t and you own the property outright.
Costs You Can Recover If the Owner Redeems
On top of the purchase price and premium, a redeeming owner must reimburse you for certain costs you incurred while holding the property. The statute lists them:4State of Texas. Tax Code 34.21 – Right of Redemption
- Property insurance.
- Repairs or improvements required by a local building code or ordinance, or by an existing lease.
- Municipal health or safety liens you paid to discharge.
- HOA dues or assessments paid under a recorded restrictive covenant.
- Impact or standby fees paid to a political subdivision.
Keep meticulous records of every dollar. If the former owner asks for an itemization of your costs, you must provide one, and only amounts included in that itemization can be recovered at redemption. Spending money on the property without documenting it is the same, for reimbursement purposes, as not spending it.
Clearing Title After Redemption Expires
When the redemption window passes without payment, your title gets significantly stronger, but it isn’t automatically bulletproof. The former owner or another party can still challenge the validity of the tax sale in court, subject to strict deadlines. For most properties, any challenge must be filed within one year of the date your deed was recorded. For homestead or agricultural properties, the deadline is two years.5State of Texas. Texas Code Tax 33.54 – Limitation on Actions Relating to Property Sold for Taxes
Once those deadlines pass, the statute bars further claims and grants the purchaser full title. One exception: a person who was never served with citation in the original tax foreclosure suit and who paid taxes on the property during the limitations period can still bring a challenge.
Many investors file a quiet title suit after redemption expires, especially if they plan to sell or finance the property. Title insurance companies are often reluctant to insure a tax deed without a court order confirming the title is clear. A quiet title action asks the court to declare that no other party has a valid claim. Treat that cost as a built-in expense of the investment rather than a surprise at exit.
Risks That Shape the Return
Properties sell as-is with no interior inspection. Environmental contamination, structural damage, and code violations can all be hiding behind a minimum bid that looks cheap. A serious environmental problem can carry cleanup liability that dwarfs the purchase price.
Redemption risk cuts both directions. If you’re counting on the 25% or 50% premium from a homestead, the owner has two full years to redeem. Your capital is tied up that whole time, and you’re responsible for maintaining the property in the meantime. If you’re betting on keeping the property, a last-minute redemption hands it back and leaves you with only the premium and documented costs.
Competition at tax sales in the major Texas metros has intensified. In counties like Harris, Travis, and Dallas, experienced investors and institutional buyers routinely bid properties well above the minimum, compressing returns. Better opportunities tend to appear in smaller counties with fewer bidders, though those properties come with limited resale markets, longer holding periods, and less municipal infrastructure. Matching your strategy to the county you’re buying in is where the actual skill lives.
