At the beginning of each year, Portuguese taxpayers can log in to the Portuguese tax authority web page to confirm or communicate their household (family unit). This service is located under the PIT section, in “Personal data relevant for PIT return” and “Household data.” Each household member’s tax ID and login credentials are required to authenticate their inclusion.
The communication must reflect the situation as of 31 December of the previous year. If there have been no changes, taxpayers can simply confirm the pre-filled information. Any changes, such as the birth of a child, marriage, divorce, or change of permanent residence, must be reported.
The household unit for IRS purposes includes spouses or civil partners and their dependents under Portuguese tax law.
Deadlines to submit this communication usually span from 1 January to mid-February, often with a final date around 15 or 17 February depending on the tax year.
Accurate household communication allows:
- Correct pre-filled PIT returns.
- Eligibility for automatic IRS where applicable.
- Proper application of deductions and social benefits.
Conclusion
Updating or confirming your household information on the Portuguese tax authority web page is a crucial step to ensure that your income tax return corresponds to your real family situation. Missing the deadline could lead to inaccuracies in your tax filing.
