- Go to the e-Fatura portal (faturas.portaldasfinancas.gov.pt) or the e-Fatura app — using your Tax Authority password, Digital Mobile Key, or Citizen Card.
- In "Verify invoices" you see those issued with your NIF (Portuguese tax identification number); validate or correct the classification of pending ones (health, education, housing…).
- You can register any missing ones yourself — in the app even via the invoice’s QR code, even if it wasn’t issued with your NIF.
- For IRS (Portuguese personal income tax) purposes, the year’s validation must be completed by the end of the following February; from March 15 you can already view the expenses counted for deductions.
If you have independent activity, indicate whether each expense was made within that activity — it changes the deduction.
