Portugal Corporate Tax Calculator 2026 (Modelo 22)

Portugal's corporate income tax (IRC) has a general rate of 19% in 2026. SMEs and small mid caps pay 15% on the first €50,000 of taxable income and 19% above that. A municipal surcharge of up to 1.5% of taxable profit applies, plus a state surcharge once profit exceeds €1.5 million.

How the tax is assessed

• Assessment — the rate applied to taxable income: 15% on the first €50,000 for SMEs, 19% on the rest (article 87 CIRC).
• Municipal surcharge — up to 1.5% of taxable profit, decided annually by the head-office municipality. It ranges from 0% to 1.5% and some councils waive it below a turnover threshold.
• State surcharge — 3% on the portion of taxable profit between €1.5m and €7.5m, 5% between €7.5m and €35m, and 9% above €35m (article 87-A).
• Deductions — payments on account already made during the period are deducted from the assessed tax, giving the balance payable or recoverable.

What this calculator does not include

Autonomous taxation is not part of this calculation: it falls on specific expenses — company cars, per diems, entertainment — rather than on profit, and is added afterwards. Use the autonomous taxation calculator to estimate it.

Filing deadline

Article 120 CIRC sets filing at the last day of May of the year following the tax period. In practice it has been extended: for the 2025 period it moved from 31 May to 19 June 2026 by ministerial order, with payment allowed by the same date without surcharges. Always check the current year's order before planning cash flow.

After the Modelo 22 come the following year's payments on account, calculated on the assessment just determined. Informative simulation prepared by HVR Business Consulting; it does not replace case-by-case analysis by a certified accountant.
