The annual filing process

  1. April-June each year - file Modelo 3 covering the previous calendar year.
  2. NIF (tax number) and certified accountant required for most expats.
  3. Pre-filled returns for Portuguese-source income are usually visible in the Portal das Financas in March-April.
  4. Worldwide income must be added by the taxpayer for residents.
  5. Deductions for dependants, health expenses, education, housing, donations, retirement contributions.
  6. Refund or payment usually settled by July-August.

Common deductions

Deduction limits scale with household income and number of dependants. A specialist accountant maximises legitimate deductions which can save EUR 500-3,000+ annually.

FAQ

Frequently asked questions

What's e-fatura?+

Portugal's electronic invoicing system. When merchants record receipts against your NIF, certain VAT amounts become deductible from your IRS. Small individually (typically EUR 10-50/year per category), worth registering NIF on receipts.

Can I file IRS without an accountant?+

Technically yes - the Portal das Financas is in Portuguese and English (partial). For simple resident salary cases with pre-filled returns, possible. For self-employed, expat-with-foreign-income, capital gains, or anyone with complexity, a certified Portuguese accountant is strongly recommended.
