US Expat Tax in Germany & Western Europe (DIY Guide + Checklist)

If you are a U.S. citizen living in Germany, Portugal, or elsewhere in Western Europe, you are still required to file U.S. taxes every year.

This applies even if:

  • You live permanently abroad
  • You pay full local taxes
  • You owe nothing to the IRS

Many expats attempt to handle their U.S. tax filing themselves.

That is absolutely possible—if you approach it in a structured way.


Do U.S. Expats in Germany Have to File Taxes?

Yes.

If you are a U.S. citizen or green card holder, you must file:

  • Form 1040 (U.S. tax return)
  • Additional expat reporting (depending on your situation)

This applies regardless of where you live.

Living in Germany or Portugal does not eliminate your U.S. tax obligations.

    Payment deadline (most important)
  • June 15, 2026

👉 Even if you file later, interest starts from April 15 if tax is owed.


What Forms Do U.S. Expats Need?

Most U.S. expats in Germany and Europe will encounter:

Core Filing

  • Form 1040

Expat-Specific Forms

  • Form 2555 (Foreign Earned Income Exclusion)
  • Form 1116 (Foreign Tax Credit)
  • FBAR (foreign accounts > $10,000)
  • Form 8938 (FATCA reporting)

Germany vs Portugal: What Actually Changes

The U.S. system is consistent. The difference is coordination.

Germany (Frankfurt, Hamburg)

  • Local filing deadline typically July 31
  • Common approach:
    • Finalize German taxes first
    • Use Form 1116 (Foreign Tax Credit)

Portugal (e.g., Cascais)

  • Calendar-year system
  • Requires:
    • Reliable local tax assessment or estimate

👉 In both cases, correct coordination usually eliminates double taxation.


How to Do Your U.S. Expat Taxes Yourself

A typical DIY process looks like this:

Step 1 — Confirm you must file

If you are a U.S. citizen → you file annually.

Step 2 — Gather documents

  • Salary statements
  • Local tax assessments
  • Bank and investment records

Step 3 — Convert income to USD

All income must be reported in USD:

  • Salary
  • Dividends
  • Capital gains

Step 4 — Decide: FEIE vs FTC

This is the most important step:

  • Germany / high-tax countries
    → Form 1116 (FTC) is usually better
  • Simpler cases
    → Form 2555 (FEIE) may work

Step 5 — Prepare and file

  • Complete Form 1040
  • Add schedules and expat forms
  • File FBAR separately

To make this easier, I provide a structured “prep-by-client” checklist used in real engagements.

This includes exactly what you need to gather before filing:

  • Prior U.S. tax returns (3–5 years)
  • Worldwide income and foreign tax documents
  • Bank and investment account details (FBAR/FATCA)

👉 This is the same structure used to:

What to Prepare If You Want a Professional Review

If you plan to have your return reviewed, preparing upfront saves time and cost.

1. Identity & Prior Returns

  • Last 3–5 years of U.S. tax returns
  • Any IRS notices
  • Prior Form 2555 / 1116 filings

2. Income & Foreign Tax

  • Salary and payslips
  • Foreign tax assessments (Germany / Portugal)
  • Investment income (interest, dividends, gains)
  • Rental or business income

3. Foreign Accounts & Assets

  • All non-U.S. bank and brokerage accounts
  • Maximum balances during the year
  • Pension and insurance details

4. Entities & Investments

  • Company ownership documents
  • Stock options / RSUs
  • Partnerships or side businesses

5. Residency & Travel

  • Travel calendar (days in/out of U.S.)
  • Residency permits / visas
  • Lease or housing contracts

A clean document package upfront is the single biggest driver of an efficient and accurate filing.


Common Mistakes U.S. Expats Make

Most DIY filings are submitted—but not optimized.

Typical issues:

  • Wrong choice between FEIE vs FTC
  • Missing FBAR filings
  • Incorrect currency conversion
  • Misalignment with local tax filings
  • Investment income handled incorrectly

These issues often compound over multiple years.

Prepare your return yourself → get a professional review once

This ensures:

  • Correct structure
  • Optimized tax position
  • No missed filings
  • Confidence going forward
