Texas sourcing, the origin point, the local cap and the policies. Each row saves on its own. Rates are fractions: 0.0625 = 6.25%.
Check an address
Geocode any address and, for Texas, list the jurisdictions and codes the boundary service returns. Use it to confirm the origin point or to spot-check a customer.
Nexus by state
"Collects" means Moss Seal is registered there and charges tax. Everything except Texas is unconfirmed until Taylor marks it. Rate source: Texas uses the Comptroller boundary service plus its rate tables; every other state uses the State rates table below plus any Local rate overrides.
Local rate overrides
Local rates for non-Texas ship-tos, by state and county/parish FIPS (the geocoder reports it; * = statewide default). Fill from the state's official lookup (Louisiana: the LULSTB Sales Tax Rate Lookup Tool, which must be used by hand; its terms forbid automated access). Cite the source and date on every row.
State rates
Reference table, refreshed by hand. Average local is an estimate for the "Needs review" message, never a rate to charge. Source and as-of date are shown on every decision that uses a row.
