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

What’s included

✅ Intake review + clear document checklist

✅ Annex selection and completion based on your fact pattern (including foreign income annexes where applicable)

✅ e-Fatura validation and reconciliation

✅ Draft preparation + a plain-English summary of key reporting positions

✅ Submission via Portal das Finanças after you approve, with filing confirmation and key figures

✅ Reasonable clarification loop to finalize the draft (no surprise work without surfacing options)

Standard turnaround: 10 business days from complete document receipt.

What’s not included

(unless separately scoped)

❌ Audit representation, litigation, or disputes with the tax authority

❌ Complex multi-entity or multi-jurisdiction business structures

❌ Large-volume trading / highly complex capital gains computations beyond standard scope

❌ Non-standard international reporting that requires separate technical scoping

❌ U.S. state returns (for the coordinated option)

If we identify work outside the standard scope, we will flag it and present options before proceeding.

Prefer coordinated filing? Add Portugal + U.S. (optional)

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 checkout below. Email us before paying if you need the Portugal + U.S. path.

FBAR (FinCEN Form 114)

Generally due April 15, with an automatic extension to October 15.

We do not collect SSN/ITIN on this checkout page
