Texas Sales Tax Calculator (2026) — Add or Reverse Tax
Texas's combined sales tax rate is 8.20% (6.25% state + 1.95% average local). Use the calculator below to add Texas sales tax to a price, or reverse a tax-included total to find the pre-tax price and exact tax amount.
How to use this calculator:
- Adding tax — enter a pre-tax price, pick "Add tax to price," and the calculator applies the Texas rate to show the tax amount and final total.
- Reversing (extracting) tax — enter a total that already includes tax, pick "Extract tax from total," and the calculator divides by 1 + the rate to isolate the pre-tax price and the exact tax paid.
- Pick the rate that matches your situation: the average combined rate is a good statewide estimate, but the state-only or maximum-local rate is more precise if you know the exact city or county.
Understanding Texas Sales Tax

Why Reverse Sales Tax Calculation Matters
Receipts and marketplace payouts usually show only the tax-included total, so separating revenue from tax collected — for bookkeeping, expense reports, or checking what an item costs before Texas's tax is applied — means working backward from that total. Dividing by (1 + rate) isn't the same as subtracting the rate, which is why the calculator above handles it exactly.

How Texas Fits Into the US Sales Tax System
The United States has no federal sales tax — unlike VAT/GST countries where a national rate applies everywhere, US sales tax is set entirely at the state level, and each of the 50 states (plus DC) independently decides whether to levy one, what the rate is, and what's exempt. Texas is one of the 45 states (plus DC) that levies a general sales tax. States can also authorize cities, counties, and special districts to add their own local rate on top of the state rate — which is why the "combined rate" shown on this page is a blend, not a single fixed number, and why it can differ from the state rate alone by several percentage points depending on the exact delivery address.
History & Rate Breakdown
Texas enacted its Limited Sales and Use Tax in 1961 at a 2% rate. Cities gained local option authority in 1967, when the legislature let them add up to 1% by voter approval — since expanded to a total local cap of 2%.
Texas's 8.2% average combined rate stacks the 6.25% state rate with city, county, transit, and special-purpose district taxes capped at a combined 2% locally, averaging 1.95% statewide.
Where the Money Goes
With no state income tax, Texas leans on sales tax — helped by its high $500,000 economic nexus threshold, one of the highest in the country — plus franchise (margin) tax on businesses and property tax to fund state and local government.
Business Use Case: Registering & Collecting Texas Sales Tax
An online retailer whose Texas sales exceed $500,000 in a year — a notably high bar compared to the $100,000 standard most states use — must register with the Texas Comptroller and apply the correct combined rate (up to 8.25%) for each delivery address, accounting for whichever mix of city, county, transit, and special-district taxes applies there.
Key terms: combined rate — state rate plus applicable local add-ons; reverse sales tax — working backward from a tax-included total via total ÷ (1 + rate); economic nexus — a sales threshold that obligates an out-of-state seller to collect tax without a physical presence; marketplace facilitator — a platform that remits tax on behalf of third-party sellers.
Real-World Example: Adding Tax to a Price
A $500.00 purchase in Texas at the average combined rate of 8.20%:
- Tax amount: $500.00 × 8.20% = $41.00
- Total price: $500.00 + $41.00 = $541.00
Real-World Example: Extracting Tax From a Receipt Total
A receipt shows a $749.99 tax-included total in Texas at the average combined rate of 8.20%:
- Pre-tax price: $749.99 ÷ (1 + 8.20%) = $693.15
- Tax amount: $749.99 − $693.15 = $56.84
Texas Sales Tax Compliance for Sellers
Remote and online sellers establish economic nexus in Texas once they exceed $500,000.00 in annual sales (no separate transaction-count test). Once nexus is established, a seller must register with the state, collect Texas sales tax at checkout, and file returns on the state's required schedule. Marketplace facilitators (Amazon, Etsy, eBay, Walmart) generally collect and remit on behalf of third-party sellers automatically.
