How Sales Tax Works in Texas
Texas imposes a statewide base sales tax rate of 6.25%. Texas is an origin-based sales tax state, meaning the tax rate is determined by the seller's location for in-state sales.
County taxes: Texas counties can levy additional sales tax on top of the state rate, and rates vary by county.
City taxes: Cities in Texas may impose their own sales tax, adding further variability to combined rates.
Special district taxes: Special taxing districts (transit authorities, improvement districts, etc.) in Texas can add additional taxes that apply within their boundaries.
Rates in Texas are typically updated quarterly. Businesses should monitor rate changes regularly to maintain compliance.
Why Rates Vary by County in Texas
The combined sales tax rate a customer pays in Texas depends on the specific jurisdiction of the transaction. Local governments use sales tax revenue to fund essential services such as infrastructure, public safety, and education.
This means that two addresses within the same city may have different tax rates if they fall in different special taxing districts. ZIP codes are particularly unreliable for tax determination because a single ZIP code can span multiple counties or tax jurisdictions.
For businesses operating in Texas, manually tracking these rate changes across every jurisdiction is impractical. An automated API solution ensures you always apply the correct rate at the point of sale, reducing compliance risk and audit exposure.
