Sales Tax API

TaxLite is a general sales tax API with address-level jurisdiction matching (including special districts), plus reporting and filing-ready exports built from recorded transactions.

• Address-level accuracy: avoid ZIP-level approximations when boundaries matter.
• Filing-ready exports: bucket totals you can export for returns.
• Transparent pricing: API access from $25/mo with published overage.
