Free, weekly-updated US sales-tax rate tables — the flat data behind TaxLocus, released as an open dataset for the community.
Data as of: 2026-05-19 · Refreshed weekly from the live TaxLocus corpus.
A clean, flat snapshot of US sales-tax rates and rules:
- State base rates for all sales-tax states.
- Local jurisdiction rates — ~14,000 counties, cities, parishes, boroughs, transit and special districts.
- Economic-nexus thresholds — the per-state remote-seller registration triggers.
- Taxability matrix — state × product-category taxable/exempt treatment.
Both CSV and JSON are provided for every table.
This is the rate data only. The address-level lookup API, the polygon geometry that resolves an address to its jurisdiction stack, and the nexus tracking tools are the paid product at taxlocus.com. This dataset will tell you the rate for a named jurisdiction; it will not tell you which jurisdictions a given street address falls in.
