Retiring abroad is a dream for many, but U.S. citizens still have U.S. tax obligations. Understanding the tax rules for Americans living overseas helps you plan and avoid costly mistakes.
U.S. Tax Obligations Abroad
The Rule
U.S. Citizens Are Taxed Worldwide:
- Must file U.S. tax return
- Report worldwide income
- Why: Citizenship-based taxation
Key Point: Living abroad doesn't eliminate U.S. tax obligations.
What's Taxable
All Income:
- U.S. income
- Foreign income
- Why: Worldwide taxation
Example:
- U.S. Social Security: Taxable
- Foreign pension: Taxable
- Foreign investment income: Taxable
- All taxable: To U.S.
Foreign Earned Income Exclusion
What It Is
Foreign Earned Income Exclusion (FEIE):
- Exclude up to $126,500 (2026) of earned income
- If meet requirements
- Why: Reduces U.S. tax on foreign earned income
Key Point: Only for earned income (wages, self-employment), not retirement income.
Requirements
Must Meet All:
- Tax home in foreign country
- Physical presence test: 330 days in 12 months, OR
- Bona fide residence test: Resident of foreign country
- Why: Strict requirements
Note: FEIE doesn't apply to retirement income (pensions, Social Security, IRA distributions).
Foreign Tax Credit
What It Is
Foreign Tax Credit:
- Credit for taxes paid to foreign country
- Reduces U.S. tax
- Why: Avoids double taxation
Example:
- Foreign tax: $5,000
- U.S. tax: $6,000
- Credit: $5,000: Reduces U.S. tax to $1,000
How It Works
Credit Calculation:
- Tax paid to foreign country
- Credit up to U.S. tax on that income
- Why: Prevents double taxation
Example:
- Foreign income: $50,000
- Foreign tax: $10,000 (20%)
- U.S. tax: $11,000 (22%)
- Credit: $10,000: Reduces U.S. tax to $1,000
Tax Treaties
What They Are
Tax Treaties:
- Agreements between countries
- Reduce or eliminate double taxation
- Why: Prevent double taxation
Common Provisions:
- Reduced withholding rates
- Exemptions for certain income
- Why: Treaty benefits
How They Help
Reduce Double Taxation:
- Lower withholding rates
- Exemptions
- Why: Tax savings
Example:
- Pension from foreign country
- Treaty may reduce or eliminate U.S. tax
