Why Portugal IRS Filing with Foreign Income Isn’t DIY-Friendly
If you have income from outside Portugal (employment, pensions, investments, rentals, or capital gains), the correct annexes (for example, Anexo J) and consistent reporting choices matter. Small mistakes can trigger delays, inquiries, or missed deductions. We translate your cross-border facts into a correct, timely filing, with clear boundaries and a defined scope.
Foreign income (Anexo J)
Correct categorization and supporting detail to reduce follow-up requests
Special regimes (e.g., NHR / IFICI)
Correct annexing and disclosure positions where applicable
Capital gains & crypto
Clear classification and consistent reporting treatment across categories

Frequently asked questions
Is this the U.S. IRS?
No. Here, “IRS” refers to Portuguese personal income tax (Imposto sobre o Rendimento das Pessoas Singulares). This service is for Portugal’s annual tax return (Modelo 3), filed online via the Portal das Finanças.
Which year is this for?
This is for income earned in 2025 (filed in 2026).
What’s the filing deadline?
The filing window for 2025 income is 1 April to 30 June 2026.
How is foreign income handled?
Foreign-source income for Portuguese residents is typically reported via Anexo J, alongside other annexes as needed for your situation.
Can I file jointly with my spouse/partner?
If you are filing as a couple, we confirm the relevant filing basis in intake before preparation. The correct route depends on your legal and tax status and should be checked against your facts before filing.
I’m under NHR or another special regime. Does that change anything?
Possibly. NHR was closed to new entrants effective 1 January 2024 under Law 82/2023. Existing NHR holders with remaining regime years still report through Anexo L. The intake includes a quick flag so we can scope the correct annexes.
Can you assure a refund or a specific outcome?
No. Outcomes depend on your facts, documentation, and tax authority assessment.
What if I start Portugal-only but later realize I have U.S. obligations?
If you have U.S. filing obligations, coordinated preparation reduces mismatch and double-reporting risk across filings. That coordinated route is separate from the standard Portugal-only filing below. Email us before booking if you need the Portugal + U.S. path.
