Corporate income tax at 25 per cent with a narrow base and petroleum expectations

Indexed· 2026-08-03

Corporate income tax is charged at 25 per cent, with a simplified regime for small taxpayers. There is no full VAT of the regional type; consumption is taxed through a sales tax, with VAT introduction repeatedly planned. Petroleum revenues from the Joint Development Zone are governed by a dedicated oil-revenue management law.

Key rules

  • Jurisdiction — The Direcção dos Impostos assesses; appeals lie to the fiscal courts.
  • Deadline — Corporate return: by 31 March following the calendar year
  • Deadline — Sales tax returns: monthly

Governing law

  • Código do Imposto sobre o Rendimento das Pessoas Colectivas
  • Lei de Gestão das Receitas PetrolíferasLei 8/2004
  • Código Geral Tributário

In practice

The 2004 oil-revenue law was drafted with external assistance as a model transparency statute — creating a national oil account and strict reporting rules — in anticipation of petroleum income that has not yet materialised at scale.
