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

Key dates for 2025 income (filed in 2026)

Starting early helps us confirm scope, request missing documents, and avoid last-minute rush.
1 Apr to 30 Jun 2026

Filing window

Portuguese IRS (Modelo 3) for 2025 income is submitted online during this window via the Portal das Finanças.

1 Apr to 30 Jun 2026
By 31 Aug 2026

Refund/payment timing (typical legal deadline)

For returns filed within the deadline, the tax authority timeline indicates refunds (if any) and payment should be processed by this date, subject to review/processing.

By 31 Aug 2026

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 mismatches and double-reporting risk across filings. The intake will only show U.S. questions if you indicate U.S. obligations.

FBAR (FinCEN Form 114)

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

We do not collect SSN/ITIN in the public intake

Sensitive identifiers are collected only after payment via secure upload.

U.S. coordination

Does not include U.S. state returns

How it works

Start the guided intake (8 to 12 minutes)

Answer a short set of questions. Portugal-first by default; U.S. questions appear only if relevant.
