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 fixed fee.

TaxBordr is a Lisbon-based boutique firm exclusively serving Americans, British, Germans, and Canadians with tax exposure in Portugal—whether planning a move, already resident, or managing ongoing cross-border ties. Founded and led by a Portuguese native with postgraduate specialization in taxation and Big 4 international experience (EY Portugal foreign investor team and KPMG US client matters), we only take on complex cross-border cases that local accountants and general expat firms cannot handle.

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
