Texas is one of the largest surplus funds markets in the country. Harris County alone — which covers Houston and its surrounding municipalities — ranks among the top five counties nationwide for unclaimed tax sale surplus. With four major metro counties generating consistent auction volume, a favorable legal framework, and no attorney requirement for filing, Texas is a high-opportunity market for surplus recovery agents who know the system. Here's everything you need to operate in it.
The Texas Surplus Funds Landscape
When a Texas county sells a tax-delinquent property at auction for more than the amount owed in back taxes, penalties, fees, and court costs, the excess is classified as surplus. Under Texas Tax Code § 34.04, those funds belong to the former owner — or their heirs — and must be held by the county for a defined period before they can be claimed.
The Texas claim window is 2 years from the date the county deed is filed in most jurisdictions. After the window closes, unclaimed funds are transferred to the Texas Comptroller's unclaimed property fund. Two years sounds like plenty of time — until you're managing 20 active leads across multiple counties, each with a different auction date and a different deadline clock.
Texas was already a surplus-compliant state before the Tyler v. Hennepin County Supreme Court ruling in 2023. The ruling didn't create new rights in Texas — it reinforced them, and it is now a useful citation when a county disputes its obligation to disburse surplus promptly. Citing Tyler v. Hennepin County, 598 U.S. 631 (2023) in a demand letter to a slow-moving county tends to accelerate responses considerably.
Key Counties: Where the Volume Is
Harris County
Harris County is the largest county in Texas and the third-largest in the United States by population. It covers Houston and runs a high volume of constable-conducted tax sales every month. The Harris County Tax Assessor-Collector's office and the District Clerk maintain surplus records from these sales. Individual surplus amounts in Harris County regularly exceed $50,000 — fueled by Houston's high-value real estate market. The county uses an administrative process through the District Clerk, not the courts, to handle surplus disbursements. This is faster than Florida's circuit court process but has its own documentation requirements. The Harris County demo case in SurplusAI is a real example of the pipeline this county generates.
Dallas County
Dallas County runs regular tax sales through the Dallas County Tax Office and publishes results through the county's online records portal. Dallas produces strong mid-to-high-range surplus amounts — driven by the Dallas-Fort Worth metro's real estate appreciation over the past decade. The county uses a court-based process for surplus claims, filed with the District Court. Dallas is a high-volume market and less picked-over than Harris County, making it a strong secondary target for agents expanding their Texas footprint.
Tarrant County
Tarrant County (Fort Worth) generates consistent tax deed auction volume and publishes surplus information through the Tarrant County Tax Assessor-Collector's website. Claims are processed through the District Court, similar to Dallas County. Fort Worth's growth as a standalone metro — not just a DFW suburb — means Tarrant County produces surplus from a wide range of property types: single-family homes, commercial properties, and investment units. Strong mid-range market for agents who want volume alongside reasonable case complexity.
Bexar County
Bexar County covers San Antonio — Texas's second-largest city — and runs regular constable sales that generate consistent surplus. The Bexar County Tax Assessor-Collector and District Clerk maintain surplus records searchable through the county's online portal. San Antonio's rapid growth over the past five years has pushed property values up significantly, which increases the frequency and size of surplus amounts. Bexar is a growing market with less agent competition than Harris or Dallas, making it worth prioritizing as you build your Texas pipeline.
Texas Statutes and Filing Requirements
The governing statute is Texas Tax Code § 34.04 — Claims for Excess Proceeds. Key provisions:
- Who can claim — The former owner of record, their heirs, or an authorized agent acting under a written agreement with the claimant.
- Filing venue — Varies by county. Harris County: administrative process through the District Clerk. Dallas, Tarrant, Bexar: petition filed with the District Court in the county where the property was located.
- Claim deadline — 2 years from the date the deed is filed following the tax sale. After 2 years, unclaimed surplus is remitted to the Texas Comptroller under the Unclaimed Property Act.
- Required documents — Petition for excess proceeds (or county-specific claim form), proof of former ownership (recorded deed predating the tax sale), government-issued ID, and if filing as an agent: a signed written agreement from the claimant authorizing you to act on their behalf.
- Fee caps — Texas does not cap recovery agent fees by statute. Contingency fees of 30–40% are standard and enforceable, provided they are clearly disclosed in the written agreement with the claimant.
The Texas Filing Process Step by Step
Step 1 — Verify the Surplus Exists
Search the county's online records portal for tax sale results. For Harris County, start with the District Clerk's office online database. For Dallas, Tarrant, and Bexar, check the respective Tax Assessor-Collector and District Clerk websites. Verify the surplus amount, the date the county deed was filed, and calculate the 2-year deadline. Log that deadline in your CRM before doing anything else.
Step 2 — Locate the Former Owner
Pull the property's deed history from the county appraisal district website — each Texas county's central appraisal district (HCAD for Harris, DCAD for Dallas, TCAD for Tarrant, BCAD for Bexar) maintains ownership history and prior mailing addresses. Cross-reference with TLO, IRB Search, or BeenVerified to find a current address. For deceased owners, search the county probate court index for an open estate. Texas has strong public records access — most searches that fail on the first database succeed on the second.
Step 3 — Get a Signed Written Agreement
Your written agreement with the claimant must clearly state your contingency percentage, the specific surplus funds you're pursuing, the services you will provide, and that the client owes nothing out of pocket. Under Texas Tax Code § 34.04, the written agreement is required documentation — without it, the county will not accept a claim filed by a third party.
Step 4 — File the Claim
For Harris County: File a petition for excess proceeds with the Harris County District Clerk's office. The petition must include the tax case number, the surplus amount claimed, your written agreement with the claimant, and proof of prior ownership. Harris County's administrative process is faster than court-based filing — typical disbursement is 30–60 days from a complete filing. For Dallas, Tarrant, and Bexar counties: File a petition with the District Court in the county of sale. Attach the same documentation. Court processing runs 60–90 days in most cases, though backlogs can extend this.
Step 5 — Collect and Close
Once the county or court approves the claim, funds are disbursed by check or wire. Your contingency fee is paid from the proceeds. Close the case in your CRM, document the outcome, and move to the next lead. In Harris County specifically, the turnaround from approved claim to disbursement is typically faster than court-based counties — budget 30–45 days post-approval.
How to Find Texas Surplus Listings
The most reliable sources for Texas surplus leads:
- County Tax Assessor-Collector websites — Each Texas county publishes tax sale results. Harris, Dallas, Tarrant, and Bexar all have searchable online portals. Search for "excess proceeds," "tax sale surplus," or "overbid" in the county's online records system.
- District Clerk online portals — Tax deed cases and surplus petitions are filed with the District Clerk. Searching pending or recent cases labeled "excess proceeds" surfaces active claims and unclaimed surplus.
- Central Appraisal District (CAD) records — Each county's CAD maintains property ownership history. Cross-referencing CAD records with tax sale results identifies properties sold above their assessed value — a reliable proxy for surplus.
- Texas Comptroller Unclaimed Property database — Surplus that has already escheated after the 2-year window is held by the state. These claims are harder but still recoverable for former owners who missed the county deadline.
- SurplusAI lead database — Pre-verified Texas surplus leads across Harris, Dallas, Bexar, Travis, and Tarrant counties, filtered by surplus amount and deadline proximity. Eliminates the manual county scraping step.
Common Pitfalls in Texas Surplus Recovery
Confusing County Processes
Texas's biggest pitfall: each county sets its own process within the framework of § 34.04. Harris County's administrative filing through the District Clerk is fundamentally different from the court-petition process in Dallas, Tarrant, or Bexar. Filing a court-style petition in Harris County, or trying to use the administrative process in a court-based county, wastes time and risks a rejection. Always verify the specific county's process before preparing documents.
Missing the 2-Year Deadline
Two years feels long. It goes fast when you're working leads across multiple Texas counties, each with a different clock. The deadline runs from the date the deed is filed — not the auction date, not the date you found the lead. Log the exact deed filing date and calculate the deadline on day one. Set a 60-day alert and a 30-day final warning. A Texas claim filed one day late will be referred to the Comptroller's unclaimed property fund.
Skipping the Appraisal District Records
Many Texas agents go straight to skip tracing databases and skip the county appraisal district (CAD) entirely. This is a mistake. HCAD, DCAD, TCAD, and BCAD all publish current and historical ownership records online, often including mailing addresses where tax bills were sent — which frequently differ from the property address. CAD records are your free first step before spending money on TLO or IRB Search.
Competing Mortgage or Judgment Liens
Texas tax sales extinguish most junior liens, but not all claims on surplus. Mortgage lenders and judgment creditors can sometimes file competing claims on excess proceeds. Run a title search before filing to identify any competing interests. If another party has already filed, the court sets a priority hearing — having an attorney for that proceeding is worth the cost.
How SurplusAI Supports Texas Recovery
SurplusAI's demo case is a real Harris County lead — $47,200 in surplus from a 2024 auction, with a deadline in Q3 2026. That's not a placeholder. It's the actual kind of case the platform was built around. The lead database includes verified surplus across Harris, Dallas, Bexar, Travis, and Tarrant counties, with surplus amounts, auction dates, and deadline countdowns pre-populated.
The AI document generator produces Texas-specific demand letters, written fee agreements, and outreach correspondence in one click — pre-populated with the correct statute citation (Texas Tax Code § 34.04) and county-appropriate filing language. For agents running multiple Texas counties simultaneously, the 5-stage CRM pipeline tracks every active claim with deadline alerts so nothing ages out unnoticed.
