## US INTERNATIONAL TAX BASICS

```
US TAXATION OF INTERNATIONAL INCOME
══════════════════════════════════════════════════════════════

THE US SYSTEM:
─────────────────────────────────────────────────────────────
US taxes citizens and residents on WORLDWIDE income
Unlike most countries that use territorial taxation
This means US persons owe US tax regardless of where they live

WHO IS A "US PERSON"?
─────────────────────────────────────────────────────────────
• US citizens (even living abroad)
• Green card holders
• Substantial presence test passers
• Certain visa holders

AVOIDING DOUBLE TAXATION:
─────────────────────────────────────────────────────────────
Method 1: Foreign Tax Credit (FTC)
→ Credit foreign taxes paid against US tax liability

Method 2: Foreign Earned Income Exclusion (FEIE)
→ Exclude foreign earned income from US taxation

Method 3: Tax Treaties
→ Specific provisions to prevent double taxation
```

## FOREIGN EARNED INCOME EXCLUSION

```
FEIE EXPLAINED (2024)
══════════════════════════════════════════════════════════════

WHAT IT IS:
Exclude up to $126,500 (2024) of foreign earned income
Plus housing exclusion/deduction

QUALIFICATION TESTS (meet ONE):
─────────────────────────────────────────────────────────────
BONA FIDE RESIDENCE TEST:
• Resident of foreign country for full calendar year
• Intend to stay indefinitely
• Established ties to foreign country

PHYSICAL PRESENCE TEST:
• Present in foreign country 330 days in 12-month period
• Doesn't need to be calendar year
• Count any 12-month period that includes tax year

TAX HOME REQUIREMENT (both tests):
─────────────────────────────────────────────────────────────
Your "tax home" must be in a foreign country
Tax home = main place of business/employment
If you have no regular work location, where you regularly live

WHAT QUALIFIES AS EARNED INCOME:
─────────────────────────────────────────────────────────────
✓ Wages and salaries
✓ Self-employment income
✓ Professional fees

✗ NOT: Investment income, dividends, interest
✗ NOT: Pension or retirement income
✗ NOT: Rental income (generally)
```

## FOREIGN TAX CREDIT

```
FOREIGN TAX CREDIT (FTC)
══════════════════════════════════════════════════════════════

WHAT IT IS:
Dollar-for-dollar credit for foreign taxes paid
Reduces US tax liability directly

WHEN TO USE FTC vs FEIE:
─────────────────────────────────────────────────────────────
FEIE better when:
• Foreign country has LOW or NO income tax
• Income is below exclusion amount
• Examples: UAE, Monaco, Bahamas

FTC better when:
• Foreign country has HIGH income tax (>US rates)
• Significant investment income
• Examples: Germany, UK, Japan

CAN USE BOTH:
• FEIE for earned income
• FTC for income not covered by FEIE
• But can't double-dip (no FTC on excluded income)

FTC CALCULATION:
─────────────────────────────────────────────────────────────
FTC Limit = US Tax × (Foreign Source Income / Worldwide Income)

Example:
US tax liability: $50,000
Foreign income: $150,000
Worldwide income: $200,000
Foreign tax paid: $45,000

FTC Limit: $50,000 × ($150K / $200K) = $37,500
Can only credit $37,500 (not full $45,000)
Excess $7,500 can carry forward 10 years
```
