Texas Sales Tax Calculator (8.20% Combined Rate)
Texas's state rate is a flat 6.25% and local jurisdictions can add up to 2% in any combination of county, city, transit, and special-district levies — capped at 8.25% total. Most metros sit at the 8.25% cap. The Tax Foundation pegs Texas's combined state+local rate at 8.20% for 2026 — that's what this calculator applies to your purchase amount. Estimated using the combined state + average local rate; actual rate depends on your exact location (city/ZIP).

How This Calculator Works
Texas's 2% local cap is unusual — most states let local jurisdictions stack rates without a ceiling. The cap means Houston and Dallas couldn't, even if their councils voted to, push the combined rate above 8.25%. Texas also runs three sales-tax holidays per year (back-to-school in August, Emergency Preparation Supplies in April, Energy Star products in May), each lasting a single weekend with specific category exemptions. The August holiday alone moves roughly $200 million in retail sales tax-free per year. The 6.25% Texas statutory portion plus local layers reach 8.20% on the Tax Foundation's 2026 combined-rate map. Enter the pre-tax amount; the page returns Texas sales tax and total. At a Houston, Dallas, San Antonio register the actual rate runs higher; in small West Texas counties without city add-ons closer to 6.25%. Texas exempts groceries, prescription drugs, and over-the-counter drugs with a prescription. Most professional services are not taxed, though some specific services (data processing, information services, security) are. Clothing is fully taxable except during the August back-to-school tax holiday.

Worked Example
$100 spent in Texas at the 8.20% combined rate adds $8.20 tax, for a total of $108.20. Texas's 2% local cap is unusual — most states let local jurisdictions stack rates without a ceiling. The cap means Houston and Dallas couldn't, even if their councils voted to, push the combined rate above 8.25%. Texas also runs three sales-tax holidays per year (back-to-school in August, Emergency Preparation Supplies in April, Energy Star products in May), each lasting a single weekend with specific category exemptions. The August holiday alone moves roughly $200 million in retail sales tax-free per year. Texas's state rate is a flat 6.25% and local jurisdictions can add up to 2% in any combination of county, city, transit, and special-district levies — capped at 8.25% total. Most metros sit at the 8.25% cap. Texas has no state income tax, so sales and property taxes are the primary revenue streams — and the comptroller is correspondingly aggressive about use-tax enforcement on out-of-state purchases, even small ones.
Key Insight
Texas has no state income tax, so sales and property taxes are the primary revenue streams — and the comptroller is correspondingly aggressive about use-tax enforcement on out-of-state purchases, even small ones. The 6.25% Texas state rate gets layered with local jurisdictions to reach the 8.20% Tax Foundation combined figure — useful as a ballpark for Texas shoppers and a sanity check for Texas-bound sellers, but a multi-jurisdiction online retailer with Texas nexus needs the destination-specific rate per ZIP (via Avalara, TaxJar, Stripe Tax). Texas exempts groceries, prescription drugs, and over-the-counter drugs with a prescription. Most professional services are not taxed, though some specific services (data processing, information services, security) are. Clothing is fully taxable except during the August back-to-school tax holiday.
Why the 'combined' rate matters
U.S. sales tax is layered: a state statutory rate plus local add-ons (county, city, special districts). For Texas, the Tax Foundation publishes a single 'combined' figure by population-weighting all local rates — 8.20% as of January 2026.
This number is useful as a ballpark for consumer-side checkout estimation and statewide comparison, but it is NOT the rate you'd see at a specific store. Two stores in the same state, five miles apart, can have different combined rates because of district-level add-ons.
Wayfair (2018) and the destination-based rate
Before 2018, online sellers only collected sales tax in states where they had physical presence. South Dakota v. Wayfair changed that: a seller exceeding economic-nexus thresholds (typically $100k in sales or 200 transactions per state per year) must collect destination-based sales tax on shipments to that state.
Practical consequence for Texas: if you buy online from an out-of-state seller above the nexus threshold, they should charge YOUR Texas combined local rate, not theirs. If you're a seller, sales-tax automation (Avalara, TaxJar, Stripe Tax) handles the per-customer destination lookup.
Frequently Asked Questions
How is Texas sales tax set at the state and local layers?
The combined state + average local rate for Texas is 8.20% in 2026 (Tax Foundation). Texas's state rate is a flat 6.25% and local jurisdictions can add up to 2% in any combination of county, city, transit, and special-district levies — capped at 8.25% total. Most metros sit at the 8.25% cap.
This rate is off from the one charged at a Texas store — why?
Because this is a Texas-statewide population-weighted average. Your actual rate is the 6.25% state portion plus your specific Texas city, county, and special-district add-ons. Houston, Dallas, San Antonio typically runs above the state average; small West Texas counties without city add-ons below. For exact-rate compliance, use the Texas Department of Revenue's destination-based rate lookup.
How does Texas treat groceries, medicine, and clothes?
Texas exempts groceries, prescription drugs, and over-the-counter drugs with a prescription. Most professional services are not taxed, though some specific services (data processing, information services, security) are. Clothing is fully taxable except during the August back-to-school tax holiday.
Is sales tax on Amazon or Etsy orders to Texas different?
Under South Dakota v. Wayfair (2018), sellers above an economic-nexus threshold must collect destination-based sales tax. If you're in Texas, an out-of-state seller above the threshold applies your Texas combined local rate at checkout, not their home-state rate. Texas has no state income tax, so sales and property taxes are the primary revenue streams — and the comptroller is correspondingly aggressive about use-tax enforcement on out-of-state purchases, even small ones.
How does Texas enforce use tax on online purchases?
Texas has no state income tax, so sales and property taxes are the primary revenue streams — and the comptroller is correspondingly aggressive about use-tax enforcement on out-of-state purchases, even small ones.
What edge cases break this Texas sales-tax estimate?
When the actual Texas transaction's local rate differs materially from the state population-weighted average — common in Houston, Dallas, San Antonio where district add-ons push the rate higher, or in small West Texas counties without city add-ons where it's lower. Also unreliable for Texas category exemptions (this calculator uses the general retail rate, not reduced/exempt category rates) and for cross-border online sales where the destination's rate applies. For compliance-grade Texas calculation, use a sales-tax automation tool (Avalara, TaxJar, Stripe Tax) or the Texas DOR's destination lookup.

Methodology & Review
Texas sales-tax estimator using the Tax Foundation's 2026 combined state+local figure of 8.20%. Texas's 2% local cap is unusual — most states let local jurisdictions stack rates without a ceiling. The cap means Houston and Dallas couldn't, even if their councils voted to, push the combined rate above 8.25%. Texas also runs three sales-tax holidays per year (back-to-school in August, Emergency Preparation Supplies in April, Energy Star products in May), each lasting a single weekend with specific category exemptions. The August holiday alone moves roughly $200 million in retail sales tax-free per year. Texas's state rate is a flat 6.25% and local jurisdictions can add up to 2% in any combination of county, city, transit, and special-district levies — capped at 8.25% total. Most metros sit at the 8.25% cap. The calculator multiplies the purchase by the combined rate to return tax dollars and total. Texas exempts groceries, prescription drugs, and over-the-counter drugs with a prescription. Most professional services are not taxed, though some specific services (data processing, information services, security) are. Clothing is fully taxable except during the August back-to-school tax holiday. RELIABILITY: Reliable as a Texas-average for ballpark estimation and consumer-side checkout. Less reliable for (a) exact destination-based rates where Houston, Dallas, San Antonio runs above the state average and small West Texas counties without city add-ons runs below; (b) reduced-rate or exempt categories under Texas rules; (c) cross-border online sales where Wayfair (2018) redirects to the destination rate. For compliance-grade calculation, use the Texas Department of Revenue's ZIP-based lookup or a tax-automation platform (Avalara, TaxJar, Stripe Tax).
