Portugal Corporate Tax Calculator

Summary

Enter taxable income and company type to calculate Portugal IRC tax, including the 17% SME reduced rate and municipal surtax.

How it works

1. Enter your company's taxable income for the fiscal year in euros.
2. Select whether your company qualifies as an SME (turnover ≤ €50M, balance sheet ≤ €43M, employees ≤ 250).
3. Set the applicable municipal surtax rate (0% to 1.5%) for your municipality.
4. The calculator applies 17% IRC on the first €50,000 of income for SMEs and 21% on the remainder.
5. Municipal surtax is added to the IRC base to compute total tax due.
6. Results show IRC, surtax, total tax, after-tax profit, and effective rate.
