Portugal Tax Filing 2026 is approaching fast, with the official filing period running from April 1 to June 30, 2026. If you are a tax resident in Portugal, you are required to submit your annual IRS (personal income tax) return and declare your worldwide income.
What Is Portugal Tax Filing 2026?
Portugal tax filing refers to the annual submission of your IRS (Imposto sobre o Rendimento das Pessoas Singulares) to the Autoridade Tributária e Aduaneira.

Portuguese employment income
Foreign employment income
Freelance income (including foreign clients)
Recibos verdes
Overseas pensions
Dividends and investment income
