Global tax regime

The global regime is FiscalRail's country-neutral option. It does not assume a tax authority or maintain a catalog of local rules. Your integration supplies each tax's meaning and rate when it issues the invoice.

Choose it when FiscalRail does not yet have a structured regime for the account's jurisdiction. Do not choose it to bypass a structured regime's validation: the global regime gives you flexibility, not country-specific compliance.

Customer addresses are optional under this regime, including when issuing an invoice. Your integration is responsible for collecting any recipient address required by the applicable jurisdiction.

Define every tax explicitly

Each invoice-line tax needs a stable tax and rule, a human-readable description, an effect and a treatment. Supply a rate unless the treatment is not_subject.

effect controls invoice arithmetic. An added tax increases the total; a withheld tax reduces the amount payable. treatment records whether the line is taxable, exempt, reverse_charge or not_subject.

FiscalRail validates and stores the resolved tax on the immutable invoice, but it cannot decide which custom tax applies to your sale. Your integration owns that decision.

Supported catalog

This regime defines no structured taxes or rates.

The Tax Regimes API therefore returns an empty taxes array. This is deliberate: a tax identifier that merely looks official would be worse than an explicit custom definition.

If you need FiscalRail to resolve rates, effective dates and authority codes, use a structured regime such as Spain.
