The taxation of profits remains, in 2026, one of the pillars of the Portuguese tax system, with a direct impact on the profitability of companies and self-employed professionals.
With ongoing changes in tax interpretation and increased enforcement, it is essential to understand how profits are taxed and the associated obligations.
At FA ACCOUNTING, we have observed in 2026 a growing need for strategic tax planning to avoid excessive tax burdens.
What are profits for tax purposes?
Profits correspond to the difference between:
- Revenue earned;
- Deductible costs and expenses.
They are calculated:
- ✔ Under Corporate Income Tax (IRC) – for companies
- ✔ Under Personal Income Tax (IRS) – for self-employed professionals
