What Is a TIRZ in Texas? Tax Increment Reinvestment Zones Explained

Texas Business Grants Research Team

A Tax Increment Reinvestment Zone (TIRZ) is a defined geographic area in Texas where property tax revenue growth is captured and reinvested into improvements within that zone. TIRZ districts are authorized under Chapter 311 of the Texas Tax Code and are one of the most powerful local economic development tools available to Texas cities.

How a TIRZ Works

When a city creates a TIRZ, the property tax values within the zone are frozen at their current level (the base value). As new development occurs and property values increase, the property tax revenue generated by the increment (the difference between the new value and the base value) is captured and deposited into a special fund dedicated to improvements within the zone.

This captured revenue, called tax increment, can be used for:

  • Infrastructure improvements (roads, utilities, drainage)
  • Public facilities and amenities
  • Environmental remediation
  • Affordable housing development
  • Demolition of existing structures
  • Economic development grants to businesses within the zone

How TIRZ Districts Benefit Businesses

Businesses locating or expanding within a TIRZ may benefit in several ways:

  • Infrastructure improvements: TIRZ funds can pay for road, water, sewer, and other infrastructure improvements that the business would otherwise need to fund privately.
  • Development grants: Some TIRZ districts provide direct grants or incentives to businesses that locate within the zone and contribute to increased property values.
  • Improved area conditions: TIRZ investments in public improvements, streetscaping, and amenities improve the business environment and attract customers and employees.

Where TIRZ Districts Exist in Texas

Most major Texas cities have established multiple TIRZ districts. Houston has over 20 active TIRZ zones. Dallas, San Antonio, Austin, Fort Worth, and many smaller cities also use TIRZ as a development tool. Each TIRZ has its own boundaries, project plan, and financing structure.

TIRZ vs. Other Incentive Tools

TIRZ is distinct from Chapter 380 agreements and Chapter 312 property tax abatements, though they are often used together. A TIRZ captures future tax growth for reinvestment, while a Chapter 312 abatement reduces taxes owed, and a Chapter 380 agreement provides direct financial incentives. Many large development projects use a combination of all three tools.

How to Find Out if Your Project Is in a TIRZ

  1. Contact the city's economic development office or planning department.
  2. Check the city's website for TIRZ boundary maps and project plans.
  3. Ask about available incentives within the specific TIRZ district.
  4. Review the TIRZ project and financing plan for planned infrastructure improvements.
