Unsure where you owe sales or use tax or dealing with legacy compliance pain?
Check Your ExposureTexas uses special tax districts extensively as part of its sales and use tax system. These districts are local taxing authorities that exist in addition to state, county, and city taxes. Special tax districts are one of the most common causes of incorrect tax calculation in Texas because they overlap other jurisdictions and frequently change. Understanding how these districts work is essential to accurate Texas sales and use tax compliance.
Special tax districts are local jurisdictions authorized to impose sales and use tax within defined geographic boundaries. These districts are created to fund specific public purposes such as transportation, development, or local services. Special districts apply in addition to state, county, and city taxes. A single address may fall within multiple special districts at the same time. Texas has hundreds of active special tax districts.
Texas authorizes several types of special districts, including:
Each district has its own boundaries, rate authority, and effective dates. The presence of a special district is determined by physical location, not mailing address or ZIP code.
Special district taxes increase the combined sales tax rate at a location. While Texas limits total local tax rates, the composition of those rates varies by address
Two businesses located within the same city may have different combined tax rates if one falls inside a special district and the other does not. This is why static rate tables and ZIP code based systems frequently fail in Texas.
Many retailers in Texas are affected by special purpose districts. Learn more on our Sales Tax Exposure for Retailers in Texas page.
Special districts create risk for several reasons:
Businesses that rely on simplified rate lookups often miss district applicability entirely.
Special district taxes apply to use tax in the same way they apply to sales tax. When a taxable item is purchased without Texas sales tax and later used in Texas, use tax must be calculated using the full jurisdiction rate, including applicable special districts. This is a common audit adjustment when businesses self assess use tax using only the state rate. Educational institutions and nonprofits in Texas also need to be aware of how special districts can impact their sales tax exposure. Learn more on our Sales Tax Exposure for Educational Institutions in Texas page. More on buyer responsibility is covered in the Texas use tax guide.
Remote sellers with economic nexus in Texas are required to collect sales tax at the destination rate. This includes all applicable local jurisdictions and special districts.

A broader discussion of remote seller obligations is available on the Texas economic nexus page.
Special district boundaries are legally defined geographic areas. These boundaries are not always intuitive and may cut across streets, subdivisions, or commercial zones. Postal addresses, city names, and ZIP codes are not reliable indicators of district applicability. Accurate determination requires jurisdiction level mapping based on physical location.

Texas special tax districts are not edge cases. They are a core component of the Texas sales and use tax system.
