Fiscal Document with Tax Differences
Service fiscal documents generated by fiscal document generation are actually temporary service documents (Recibo Provisório de Serviços - RPS) until the city tax authority generates the real fiscal documents.
The actual service tax (ISS) is calculated and stated by the city tax authority along with the fiscal document return even though companies calculate and report the service tax in the RPS.
