Find a tax report by period

Looks up the most recent generated tax report for a given type and period.

Returns the report or 404 tax_report_not_found when none exists for the period.

Pin the API version (YYYY-MM-DD, Stripe-style date versioning) for this request; omit to use the key's pinned version, or the latest if none. Unsupported version → 400 unsupported_api_version; malformed → 400 parameter_invalid_format. The effective version is echoed in the Factuarea-Version response header. See the Versioning guide.

Formatdate

X-Active-Profile?string

Operate on behalf of a child company (gestoría master key): pass its public id (UUID v7) and the request runs against that child's data without changing the key's scope, tier or environment (omit to use the key's own company). Invalid UUID → 400 parameter_invalid_uuid; unknown or non-owned id → 404 profile_not_found. See the Acting on behalf guide.
