Austin Sales Tax Calculator 2026 – how it works
Austin’s sales and use tax is flat-rate based and reflects a combined rate made up of two components: the Texas state sales and use tax at 6.25% and the Austin city sales and use tax at 1.00%. In practice, the combined rate is applied to the taxable sales price to estimate sales tax due. The same combined structure is used for use tax when tax is owed on taxable items or services in situations where sales tax was not collected at the time of purchase. Rate administration and published guidance are provided by the Texas Comptroller of Public Accounts (https://comptroller.texas.gov/taxes/sales/).
Examples
Example calculations below illustrate how a flat combined rate is applied. The combined rate is the Texas state sales and use tax at 6.25% plus the Austin city sales and use tax at 1.00%. If a taxable amount is multiplied by 6.25%, that produces the state portion of the estimate. If the same taxable amount is multiplied by 1.00%, that produces the Austin city portion of the estimate. Adding those two results produces the combined estimated sales tax for Austin under this simplified approach. The same combined-rate method applies when estimating use tax under the City Sales and Use Tax framework.
Limitations and important notes
Results are simplified estimates and may not match an amount calculated on an invoice or required on a filing. This estimate reflects only the Texas state sales and use tax at 6.25% and the Austin city sales and use tax at 1.00% as flat-rate components, and it does not account for transaction-specific taxability determinations, sourcing rules, rounding practices, or other administrative factors that can affect the final tax due. For authoritative determinations, published rate information and official guidance should be consulted.
FAQs about Austin Sales Tax Calculator 2026
What sales tax rates are included for Austin in this estimate?
This estimate includes two flat-rate components that apply within the described Austin context: the Texas state sales and use tax at 6.25% and the Austin city sales and use tax at 1.00%. The combined estimate is based on applying both components to the same taxable sales price and then summing the results. No other tax components are included here, and the estimate is limited to the rates explicitly listed. The approach is intended to reflect a straightforward combined-rate calculation.
How is the combined Austin sales tax estimate calculated under a flat-rate system?
Under a flat-rate system, the estimate is calculated by applying each listed rate component to the taxable amount and then adding the component results together. For Austin, that means calculating a state portion at 6.25% and a city portion at 1.00% on the same taxable base. The combined estimate is the sum of those two amounts. This method does not involve brackets, tiers, or progressive structures; it is a single-rate application per component across the taxable amount.
What is the difference between sales tax and use tax in this Austin context?
Sales tax and use tax are both part of the City Sales and Use Tax framework described here, and both are estimated using the same combined flat-rate structure. Sales tax generally refers to tax collected on taxable transactions at the time of sale. Use tax generally refers to tax owed on taxable items or services when sales tax was not collected at the time of purchase and the item is used in the taxing jurisdiction. This estimate applies the Texas 6.25% component and the Austin 1.00% component in either case.
Why might an invoice total differ from this simplified estimate?
An invoice total can differ from a simplified estimate for several factual reasons unrelated to progressive structures. Differences can arise from how taxability is determined for specific items or services, how a transaction is sourced to a location for tax purposes, and how rounding is applied at the line-item level versus the invoice level. Administrative practices and documentation can also affect what is collected or shown. This estimate is limited to applying the Texas 6.25% and Austin 1.00% flat-rate components and does not incorporate those transaction-level factors.
Does this estimate include any taxes other than the Texas state and Austin city components?
No. The estimate is limited to the components explicitly listed: the Texas state sales and use tax at 6.25% and the Austin city sales and use tax at 1.00%. It does not include any other taxes, and it does not describe or incorporate additional local components beyond the Austin city rate stated here. Because the calculation is intentionally simplified, it also does not address how particular transactions may be treated under detailed rules that can affect the final amount due.
