Tax Registration in Portugal
Registration of the company's start of activity with the AT via the Declaração de Início de Atividade — establishing it as an IRC taxpayer and, where it trades, an IVA (VAT) taxpayer — and enrolment of the company and any workers with Segurança Social. There is generally no government fee. Standard IRC is 20% for 2025 (mainland), with a reduced 16% on the first €50,000 of taxable income for qualifying SMEs; standard IVA is 23% on the mainland (22% Madeira, 16% Azores).
