Registration & When to Collect

Under Texas law, sellers with taxable activity in Houston must register with the Texas Comptroller and begin collecting sales and use tax when they make taxable sales in the city. The Texas Comptroller explains registration, collection responsibilities, and basic filing rules on its sales and use tax pages Texas Comptroller - Sales and Use Tax^[1]. Key obligations include charging the correct combined rate at point of sale and keeping complete sales records for audits.

• Register for a sales tax permit with the Texas Comptroller before collecting sales tax.
• Begin collection when you first make taxable sales in Houston; filing frequency depends on tax liability and is assigned by the Comptroller.
• Maintain receipts, exempt-sale documentation, and records for the period required by the Comptroller.

Rates & Determining Jurisdiction

The combined sales tax rate applied to a retail sale in Houston combines the Texas state rate with the applicable local rates; verify the exact rate for an address or ZIP using the Comptroller's rates tool Local Sales and Use Tax Rates^[2]. Retailers must collect the rate applicable to the location where the sale is sourced under Texas sourcing rules, which the Comptroller describes on its site.

• Combined rates change by jurisdiction; confirm the rate for each point of sale before charging customers.
• For remote sales or deliveries, follow Texas sourcing rules to determine whether Houston sales tax applies.
• Update POS tax tables and e-commerce settings when rates change or when you add new locations.

Penalties & Enforcement

Enforcement of sales tax registration, collection, and remittance for Houston retailers is administered by the Texas Comptroller. The Comptroller pursues assessments, audits, collection actions, and may impose penalties or interest for late or underpaid tax. Specific fine amounts and statutory penalty schedules should be confirmed on the Comptroller's official pages; where a numeric amount or schedule is not shown on the cited page, it is noted below as "not specified on the cited page."
