IRS: if your return left tax to pay, today is the deadline
Taxpayers who owe money after the settlement of their 2025 income — declared this year — must pay the Portuguese tax authority by today. The amount and the payment reference are on the settlement note (nota de liquidação) in Portal das Finanças.
Why it matters for your move
This catches new residents most often: the first Portuguese return frequently produces a balance to pay, because foreign income was not withheld at source during the year. Paying late adds interest and can block the tax-compliance certificate you need for residency renewals and some contracts.
