brackets are arrays of [upper_bound, rate], null = top band. Every file carries its official source and as-of year.
Thirty-eight states let counties, cities or districts add their own sales tax. The avg_local_rate column is computed by us, not copied: every incorporated city gets the local rate its state revenue department publishes for it, the unincorporated remainder of each county gets the county rate, and rates are weighted by the Census Bureau's Vintage 2024 sub-county population estimates (SUB-EST2024). Rate tables are the states' own files (Streamlined Sales Tax rate files, comptroller/DOR downloads, county rate charts) — named per state in the JSON file. Small special districts that the rate tables cannot place geographically are omitted except where the state's source line says otherwise. Recomputed quarterly.
A weekly automated check reads the official sources (IRS, SSA, state revenue departments, HMRC, CRA, ATO, incometax.gov.in, BMF, URSSAF/DGFiP) and the files are regenerated and pushed here whenever a figure changes. Mortgage rates refresh every Thursday.
