Corporate Tax

Portuguese Corporate Taxation (IRC) — 2025: Rates & Rules

If you're planning to do business in Portugal, you'll need to understand IRC — the country's corporate income tax system.

IRC operates on a company's net profits, after deductible expenses and allowances. The headline rate is only the start: the regime you fall under, your region, and your turnover all change the final figure.

Who pays IRC?

  • Resident companies (commercial, industrial or agricultural) are taxed on worldwide profits;
  • Resident entities such as associations and foundations are taxed, like individuals, on all income;
  • Non-resident companies with a permanent establishment in Portugal are taxed on Portuguese-sourced income;
  • Non-resident companies without a permanent establishment are taxed via withholding on their Portuguese income.

How IRC is calculated

  1. Determine net accounting profits;
  2. Adjust for tax provisions (add-backs and exclusions);
  3. Apply deductions — carried-forward losses and incentives;
  4. Apply the appropriate rate;
  5. Subtract prepayments and withholdings to reach the final liability.

Advance payments (Pagamentos por Conta — PPC)

Companies make three advance IRC payments based on the previous year's tax, due on 15 July, 15 September and 15 December.

  • Turnover up to €500,000 → 80% of the prior-year IRC;
  • Turnover above €500,000 → 95% of the prior-year IRC;
  • The third instalment may be skipped if sufficient tax has already been prepaid.

Surcharges

Municipal surcharge (Derrama Municipal)

Some municipalities apply an additional tax of up to 1.5%. Lisbon and Porto always apply 1.5%; small businesses with turnover under €150,000 are often exempt; Funchal applies 0% (2023–2025). CINM companies receive preferential rates.
