Cbox Tax
Cbox Tax is a free, self-hostable consumption-tax engine for Laravel applications.
What Cbox Tax is
Cbox Tax is a free, self-hostable consumption-tax engine for Laravel applications. It calculates tax treatment, rates and authority breakdowns across EU VAT, national VAT and GST, US sales tax, Canadian GST and HST, India dual GST, and Malaysia SST. Its rules address place of supply, reverse charge, inclusive or exclusive pricing, exemptions and seller-registration routing. For EU VAT, rules include intra-EU B2B reverse charge and VIES-validated customer tax IDs. US tax application checks whether the state resolves, the seller has nexus there and the product is taxable there. The engine stops when a needed regime or rate is missing rather than assuming a zero rate. A pluggable rate-source contract supports static, remote, caching or chained sources; the register syncs to local disk for pricing calculations without a network call. The package is MIT licensed, but its register data has separate PolyForm Internal Use 1.0.0 terms that bar redistribution or resale as rate lookups. The data is beta, may contain errors and is not tax advice. Requirements include PHP ^8.4, Laravel ^13, ext-dom, ext-zlib and cboxdk/laravel-geo.
Good
- Covers several VAT, GST and sales-tax regimes.
- Supports exemptions and reverse charge.
- Reads synced register data locally during pricing.
- Stops when a required rate is missing.
Watch out
- Requires PHP ^8.4 and Laravel ^13.
- Register data is beta and may contain errors.
- Register data cannot be redistributed or resold as lookups.
Who it suits
It suits Laravel teams that need a self-hosted engine for consumption-tax calculations across the listed regimes. Teams should be prepared to meet its requirements and verify tax data with an adviser.
Verdict
Cbox Tax provides configurable consumption-tax calculations for Laravel, with a fail-closed approach when rate data is missing. Check the register’s separate data terms and verify relevant figures, since the beta data is not tax advice.
