U.S. taxpayers living and working abroad often face the challenge of double taxation: their foreign income may be taxed both by the country where they work and by the United States. To mitigate this, the U.S. tax code provides two primary mechanisms: the Foreign Earned Income Exclusion (FEIE) and the Foreign Tax Credit (FTC). While both are valuable, the law strictly prohibits claiming both benefits on the same income. However, in many situations, a taxpayer may claim both in the same year—just not on the same dollars of income. This post explains the rules, allocation methods, and compliance requirements for using both the FEIE and FTC, with references to the Internal Revenue Code, Treasury Regulations, and IRS guidance.
The General Rule: No Double Benefit
Internal Revenue Code (IRC) §911(d)(6) and related Treasury Regulations establish the “no double benefit” rule:
A taxpayer may not claim a credit or deduction for foreign taxes paid or accrued on income that is excluded from gross income under the FEIE or the foreign housing exclusion.
Treas. Reg. §1.911-6(a) and IRS Publication 514 reinforce this:
You must reduce your foreign taxes available for the credit by the amount of those taxes paid or accrued on income that is excluded from U.S. income under the foreign earned income exclusion or the foreign housing exclusion
Key Point:
- You cannot claim the FTC (or a deduction) for foreign taxes paid on income you exclude under the FEIE or the foreign housing exclusion.
When Can You Claim Both FEIE and FTC in the Same Year?
You may claim both the FEIE and the FTC in the same tax year, but only for different portions of your income. This typically arises in the following situations:
1. Foreign Earned Income Exceeds the FEIE Limit
- The FEIE is capped annually (e.g., $130,000 for 2025).
- If your foreign earned income exceeds this limit, you may exclude up to the cap and must include the excess in your U.S. taxable income.
- You may claim the FTC for foreign taxes paid on the non-excluded (taxable) portion of your foreign earned income .
2. Other Types of Foreign Income
- The FEIE applies only to “foreign earned income” (generally, compensation for services performed in a foreign country).
- Foreign investment income (interest, dividends, capital gains) does not qualify for the FEIE but may be eligible for the FTC if it is included in U.S. taxable income and subject to foreign tax.
3. Partial Exclusion by Choice
- You may choose to exclude less than the maximum FEIE amount, leaving more income subject to U.S. tax and eligible for the FTC.
- This may be advantageous if the foreign tax rate is higher than the U.S. rate, as the FTC may provide a greater benefit.
How to Allocate Foreign Income and Foreign Taxes
A. Allocation of Foreign Income
- The FEIE applies only to foreign earned income as defined in IRC §911(b).
- The exclusion must be applied first to eligible income, up to the annual limit.
- Any foreign earned income above the FEIE limit (and not excluded by the foreign housing exclusion) is included in U.S. taxable income and may be eligible for the FTC if foreign taxes were paid on it.
B. Allocation of Foreign Taxes
- Only the portion of foreign taxes paid on income included in U.S. taxable income (i.e., not excluded by the FEIE or foreign housing exclusion) can be claimed as a credit.
- The allocation is made using a fraction, as described in IRS Publication 514 and the Instructions for Form 1116:
- Numerator: The amount of foreign earned income and housing amounts excluded under the FEIE and housing exclusion, minus otherwise deductible expenses allocable to that income (not including the foreign housing deduction).
- Denominator: The total foreign earned income received or accrued during the tax year, minus all deductible expenses allocable to that income (including the foreign housing deduction).
- The result is the portion of foreign taxes that must be disallowed for the FTC. The remaining portion (attributable to non-excluded income) may be claimed as a credit
Example:
Suppose you earn $150,000 in foreign earned income, exclude $130,000 under the FEIE, and pay $30,000 in foreign taxes. Only the portion of the $30,000 attributable to the $20,000 of non-excluded income is eligible for the FTC. The rest is disallowed
Special Considerations
A. Dual-Status Year
A dual-status year occurs when you are both a nonresident and a resident alien in the same year (e.g., you move to the U.S. mid-year).
- The year is split into a nonresident period and a resident period
- The FEIE and FTC are only available for the resident period.
- Income earned and foreign taxes paid during the nonresident period are generally not subject to U.S. tax and are not eligible for the FEIE or FTC.
- Only foreign earned income received during the resident period may be excluded under the FEIE, and only foreign taxes paid on income included in U.S. taxable income during the resident period may be claimed as a credit
B. Moving from a Foreign Country to the U.S.
- If you move to the U.S. mid-year, only income earned after becoming a U.S. resident is subject to U.S. tax and eligible for the FEIE or FTC.
- Income earned before U.S. residency is not subject to U.S. tax (unless you are a U.S. citizen) and is not eligible for the FEIE or FTC.
- You must allocate income and foreign taxes between the nonresident and resident periods, and only claim the FEIE and FTC for the resident period .
Procedural Requirements
1. Filing Forms
- Form 2555: Required to claim the FEIE. Attach to your Form 1040.
- Form 1116: Required to claim the FTC (unless you qualify for the simplified procedure). Attach to your Form 1040.
- In a dual-status year, you must file a dual-status return: Form 1040 for the resident period, with a Form 1040-NR as a statement for the nonresident period .
2. Recordkeeping
- Maintain records to substantiate the allocation of income and foreign taxes between excluded and non-excluded income.
- Keep documentation of foreign tax payments, income statements, and calculations used for allocation.
Summary Table: Common Scenarios
| Scenario | FEIE Allowed? | FTC Allowed? | Allocation Required? | Notes |
|---|---|---|---|---|
| Foreign earned income ≤ FEIE limit | Yes | No | No | All foreign taxes on excluded income are disallowed for FTC. |
| Foreign earned income > FEIE limit | Yes (up to limit) | Yes (on non-excluded income) | Yes | FTC only for taxes on income not excluded. |
| Foreign investment income | No | Yes | No | FTC allowed if income is included in U.S. taxable income. |
| Dual-status year (resident period only) | Yes | Yes | Yes | Only for income/taxes during U.S. residency. |
| Income earned before U.S. residency | No | No | No | Not subject to U.S. tax (unless U.S. citizen). |
Conclusion: Key Points and Compliance
- You may claim both the FEIE and the FTC in the same tax year, but only for different portions of your income.
- You cannot claim the FTC for foreign taxes paid on income you exclude under the FEIE or the foreign housing exclusion.
- You must allocate both income and foreign taxes between excluded and non-excluded income using the prescribed IRS formulas.
- Special rules apply for dual-status years and when moving to the U.S.; only income and taxes from the U.S. resident period are eligible for the FEIE and FTC.
- File Form 2555 for the FEIE, Form 1116 for the FTC, and maintain proper records to substantiate your claims and allocations.
By following these rules and maintaining proper documentation, you can maximize your tax benefits while remaining fully compliant with U.S. tax law.
