Do I have to prove income to qualify for Portuguese permanent residence?

Article 80 requires evidence that you have stable and regular means of subsistence adequate for your own needs and those of your family members. This is to show you can live in Portugal without becoming dependent on public support.

Acceptable evidence usually includes employment income, pensions, self-employment earnings or other recurring resources, supported by documents such as tax returns or bank records. Keep your financial paperwork organised and up to date so you can show consistent income across the qualifying period.
