Harris County Tax Auction Dates & Procedures 2026

Harris County is the third most populous county in the United States and home to Houston — and it runs one of the most active tax deed sale programs in the country. Properties sell every single month, auction volume is high, and the competition ranges from novice bidders to well-capitalized investment firms.

If you plan to bid in Harris County in 2026, this is what you need to know.

When Are Harris County Tax Sales Held?

Harris County Constables conduct tax deed sales on the first Tuesday of every month, year-round. The sales are held at the Harris County Civil Courthouse, located at 201 Caroline Street, Houston, TX 77002.

Sales begin at 10:00 AM and may continue through the afternoon depending on volume. High-volume months (like January and after summer) can involve hundreds of properties across multiple constable precincts running simultaneously.

How Harris County Tax Sales Work

Texas is a tax deed state, not a tax lien state. This means when Harris County sells a property at auction, the winning bidder receives a Sheriff's or Constable's deed to the property — not just a lien. You own the property (subject to redemption rights) from the moment the hammer falls.

Texas Right of Redemption

Texas law gives former owners a limited right to reclaim the property after the sale:

• Standard properties: 6-month redemption period. Former owner can reclaim by paying the purchase price plus a 25% penalty (first 6 months) or 50% penalty (second 6 months if applicable).
• Homestead and agricultural properties: 2-year redemption period. Former owner can reclaim by paying the purchase price plus 25% premium in the first year, 50% in the second.

During the redemption period, you own the property but should avoid major improvements — if redeemed, you will typically not recover improvement costs.

Registration Requirements

Harris County requires bidder registration before you can participate. Requirements include:

• Valid government-issued photo ID
• Registration with the specific Constable precinct conducting the sale (there are 8 precincts, each with their own sales)
• A deposit (amount varies by precinct — typically $1,000–$2,500 in cashier's check or cash)
• If bidding as an entity (LLC, corporation): proof of authority to bid (certificate of formation or similar)

Registration must be completed before the sale begins. Arrive at least 45 minutes early on sale day.

How Bidding Works

Properties are announced by the Constable and open for verbal bids. The opening bid is typically the total amount of delinquent taxes, penalties, fees, and court costs. Bidding proceeds in any increment the bidders call.

When bidding closes on a property, the winning bidder must be ready to pay. Full payment is required immediately — same-day. Accepted methods include cashier's check payable to the specific precinct, and cash (for smaller amounts). Personal checks and credit cards are generally not accepted.

Finding the Property List

Harris County publishes the list of properties scheduled for each sale approximately 3 weeks before the auction date. The list is available through:

• The Harris County Tax Assessor-Collector's website
• The individual Constable precinct websites
• Local legal newspapers (required by Texas statute for official notice)

Each listing includes the parcel address, legal description, assessed value, and the minimum bid. Use this list to start your due diligence — title searches, drive-bys, and comparable sales analysis — before auction day.

What Survives a Harris County Tax Sale

Texas tax deed sales extinguish most liens — but not all. The following typically survive:

• IRS federal tax liens (if the IRS was not properly notified)
• Other municipal assessments (HOA dues are often extinguished, but verify)
• Easements and deed restrictions

Always run a full title search before bidding on any Harris County property. The cost is typically $100–$300 and is money well spent.

Competition in the Houston Market

Harris County attracts serious investors. Expect competition for desirable properties — especially anything in walkable Houston neighborhoods or with clear title. Properties in areas like The Heights, EaDo, or Midtown routinely sell at or above assessed value.

The better deals are typically found in outlying Harris County communities, properties with cosmetic issues (easily fixable), or lower-value parcels that larger investors skip.
