What Foreign Tax Credits Are
- FTCs offset US tax dollar-for-dollar on income that was also taxed by another country
- They prevent the same income from being taxed twice, once abroad and once by the US
- Credits are more valuable than deductions because they reduce tax owed directly
- Taxpayers claim FTCs on Form 1116 or elect a simplified method for small amounts
FTC vs FEIE: Choosing the Right Approach
- The FEIE excludes foreign earned income; the FTC offsets US tax with foreign taxes paid
- In high-tax countries, FTCs often produce a better result by offsetting US tax fully
- In low-tax or no-tax countries, the FEIE may be preferable since few foreign taxes exist
- You cannot claim both the FEIE and FTC on the same income
The FTC Limitation
- The credit is limited to US tax attributable to your foreign source income
- Calculated as: US tax times foreign source taxable income divided by worldwide income
- If foreign taxes exceed the limit, the excess becomes a carryover
- Allocating deductions between US and foreign income can significantly affect the limit
Income Categories and Basket Rules
- Foreign income is separated into categories, each with its own limitation
- Passive category includes dividends, interest, rents, and royalties from foreign sources
- General category covers wages, business income, and other active income earned abroad
- Excess credits in one basket cannot offset a shortfall in another basket
Carryback and Carryforward Rules
- Excess foreign tax credits can be carried back one year and forward ten years
- Carryovers are applied on a first-in, first-out basis within each income category
- Careful planning can accelerate or defer income to maximize credit utilization
- Unused credits that expire after the carryforward period are permanently lost
Mutual Fund Credits and Tax Treaties
- International funds often pass through foreign taxes paid on dividends to shareholders
- For amounts under $300 ($600 joint), you may claim credits without filing Form 1116
- Tax treaties can reduce foreign withholding rates, lowering both foreign tax and the credit
- Treaty-based positions must be disclosed on Form 8833 if they reduce your US tax
Form 1116 Basics and Common Pitfalls
- Form 1116 requires separating income by category and source, which can be complex
- Only income taxes qualify for credit; VAT, property tax, and sales tax do not
- Accrual-basis election lets you claim credits when taxes accrue, not when you pay them
- Errors in source-of-income allocation are among the most common international mistakes
