Family reunification remains, as of June 2026, a fundamental right for foreign citizens legally residing in Portugal.
However, beyond immigration matters, there are tax implications that are often overlooked.
At FA ACCOUNTING, we have supported several cases where the tax component was not properly considered.
What is Family Reunification?
It allows:
- A legal resident in Portugal to bring close family members to live with them.
It includes:
- Spouse;

- Dependent ascendants (parents or grandparents).
Tax Impact of Family Reunification
Family reunification may affect:
- Family status for Personal Income Tax (IRS) purposes;
- Expense deductions;
- Household composition;
- Tax residency status of family members.
Tax Residency of Family Members
It depends on:
- Length of stay in Portugal;
- Integration into the household;
- Center of vital interests.
Risk Situations

- Errors in joint tax filing;
- Lack of tax registration for family members;
