Combined sales tax rates for every US ZIP code, current for the 2026 tax year. Each row breaks down the total rate into its state, county, city, and special district components so you can apply the correct tax at the point of sale or validate tax calculations in your accounting system.
Pro tip: Import the SQL version into your database and JOIN on zip_code at checkout to calculate tax in real time — no third-party tax API needed for basic rate lookups.

About the US Sales Tax Rates Dataset
This dataset contains combined sales tax rates for every taxable ZIP code in the United States, current for the 2026 tax year. Each record provides a complete rate breakdown — state base rate, county rate, city rate, and any applicable special district rate — along with the combined total. The data covers all 50 states plus the District of Columbia and includes rate variations down to the ZIP code level.
Common Use Cases
Sales tax compliance is one of the most complex aspects of US commerce. This dataset simplifies rate lookups for a variety of scenarios:
- E-commerce tax calculation: Look up the combined rate by ZIP code at checkout to calculate the correct sales tax without relying on a paid tax API for basic rate lookups.
- Accounting validation: Cross-reference collected tax amounts against the official combined rate for each jurisdiction to catch over- or under-collection before filing.
- Tax-inclusive pricing: Build pricing models that factor in sales tax by region, useful for businesses that advertise tax-included prices or set uniform shelf prices across states.
- Business location analysis: Compare combined tax rates across ZIP codes when evaluating potential store, warehouse, or office locations where tax burden affects competitiveness.
Column Reference
Each row represents a unique tax jurisdiction identified by its ZIP code:
- state — The two-letter US state abbreviation (e.g. "CA", "TX", "NY").
- zip_code — The five-digit ZIP code for this tax jurisdiction.
- tax_region — The name of the tax region or jurisdiction as defined by the state tax authority.
- state_rate — The base sales tax rate imposed by the state government, expressed as a decimal (e.g. 0.0625 for 6.25%).
- county_rate — The additional sales tax rate imposed by the county, if any.
- city_rate — The additional sales tax rate imposed by the city or municipality, if any.
- special_rate — Any additional special district tax (transit, stadium, tourism, etc.).
- combined_rate — The total combined sales tax rate (state + county + city + special).
Understanding US Sales Tax Structure
The US has no national sales tax. Instead, sales tax is imposed at the state level, and most states allow counties, cities, and special districts to add their own rates on top. This creates a patchwork of over 11,000 distinct tax jurisdictions. Five states — Alaska, Delaware, Montana, New Hampshire, and Oregon — have no state-level sales tax, though some Alaska municipalities impose local taxes. The combined rate for a given ZIP code is the sum of all applicable layers. Rates can change quarterly as local governments adjust their levies, so this dataset is versioned by year.
Integration Tips
For real-time tax calculation, import the SQL format into your database and create an index on the zip_code column. A simple query like SELECT combined_rate FROM tax_rates WHERE zip_code = '90210' returns the applicable rate instantly. For spreadsheet analysis, the CSV format works directly in Excel or Google Sheets — use VLOOKUP or INDEX/MATCH on the ZIP code column. Note that this dataset covers general sales tax rates; specific product categories (groceries, clothing, digital goods) may have reduced or exempt rates depending on the state.
