Key Takeaways for Americans in Portugal

You must satisfy two tax authorities (IRS + Finanças) with incompatible rules

Without coordination: double-tax risk, missed elections, and filing conflicts

Most advisors specialize in one system—we operate exclusively in the gap between them

Who This Is For

You're a US citizen or green card holder living in or moving to Portugal with:
US investments, LLCs, retirement accounts, or property

Portuguese income, residency, or assets

The need for one coherent tax strategy that works for both countries

Good Fit | Not a Fit

✅ Good Fit If

  1. Are a US citizen or green card holder with Portuguese tax obligations
  2. Have cross-border complexity (investments ≥€50k, entities, pensions, property)
  3. Need documented positions supported before both IRS and Finanças
  4. Value planning-first work with formal deliverables
  5. Have material financial stakes (€50k+ potential tax impact)
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.

❌ Not a Fit If

  1. Have simple Portuguese-only employment income (local accountant is more cost-effective)
  2. Need visa/immigration processing (we coordinate tax, don't process visas)
  3. Want aggressive "zero-tax" structures (we build compliant, defensible positions)
  4. Are seeking the lowest-cost advisory option only
  5. Need emergency same-week response

Core Coordination Challenges We Address

Client Results

Figures rounded for privacy. Past performance doesn't guarantee future results.

What Is the US-Portugal Tax Coordination Gap?

The IRS and Portuguese Finanças (Autoridade Tributária e Aduaneira) classify income, entities, and timing differently.
Your US LLC may be a partnership for federal tax but a corporation for Portuguese purposes. Your PFIC gains may be taxed at ordinary rates in the US but capital gains rates in Portugal.
Without coordinated planning, you pay more tax than either country requires—or face penalties from one authority for following the other's rules.

Frequently Asked Questions

Do Americans living in Portugal still have to file US taxes?

Yes. The US taxes worldwide income regardless of residence. Portugal taxes based on residency. You must satisfy both systems—that's the coordination challenge we solve.

What does the €500 assessment include?

A 30-minute consultation and written roadmap identifying your coordination gaps, planning opportunities, and next steps. The €500 is 100% credited toward any Annual Compliance package or Strategic Project.

Can the US-Portugal tax treaty eliminate double taxation?

The treaty provides relief mechanisms, but requires active application. The US "saving clause" means Americans cannot use the treaty to eliminate US tax on US-source income. Proper coordination maximizes available relief.

Do I need to replace my US CPA?

No. We specialize in coordinating with your existing US CPA. We handle the Portuguese side and treaty coordination, providing your CPA with the documentation needed for US filings.

How do you handle audits?

We provide full audit representation at no extra cost for positions we structure and file. We build strategies designed to withstand scrutiny from both IRS and Finanças.

What about Social Security and Medicare taxes?

The US-Portugal Totalization Agreement determines which system you pay into based on employment situation. We coordinate this to reduce dual coverage risk.

What's the deadline for IFICI?

If you became Portuguese tax resident in 2025, your deadline was January 15, 2026. Contact us to assess late filing options. For 2026 arrivals, deadline is January 15, 2027.

Do you prepare US tax returns?

We coordinate positions and provide Portugal-side data, but recommend maintaining a US CPA for return preparation. We ensure both filings tell the same story.

What documents should I prepare for our first consultation?

Recent US tax returns, Portuguese residency documents, investment statements, entity formation documents, and details of any cross-border income or assets.
