FEIE vs foreign tax credit: how the two US expat tools differ

What this covers

The foreign earned income exclusion (FEIE) and the foreign tax credit (FTC) are the two main federal rules that reduce double tax for US citizens and resident aliens with income abroad. The exclusion removes qualifying earned income from the US tax base. The credit keeps the income taxable in the US and then subtracts foreign income tax from the US tax on it. They follow different conditions, use different forms, and interact through a revocation rule that makes the choice last longer than one year.

Compare the two tools side by side

Both tools start from the same fact: Publication 54 says US citizens and resident aliens living abroad are taxed on worldwide income. They then reduce US tax in different ways. Read the table as a map of where each rule stops, not as a recommendation.

Check the three conditions for the exclusion

Publication 54 lists the requirements: a tax home in a foreign country, foreign earned income for personal services performed abroad, and either the bona fide residence test or the physical presence test. You also need a valid election by attaching Form 2555 to a return or amended return.

The physical presence test needs 330 full days in a foreign country or countries during a period of 12 consecutive months. A full day runs from midnight to midnight. You can test a date range with the FEIE physical presence calculator, which counts days but does not decide whether you qualify.

The IRS says income from working abroad as an employee of the US Government does not qualify for the exclusion. The Form 2555 instructions also say you are not treated as having a foreign tax home for any period your abode is in the United States, outside a combat-zone exception.

The cap is per person. If both spouses work abroad and each meets a test, Publication 54 says each can exclude up to the maximum, and they do not need to meet the same test.

Add the housing exclusion or deduction to the picture

Form 2555 also figures a foreign housing exclusion, for housing paid with employer-provided amounts, or a foreign housing deduction, for housing paid with self-employment earnings. Publication 54 says the housing amount is your qualifying housing expenses minus a base amount equal to 16% of the maximum exclusion, prorated by days.

Qualified housing expenses are limited. The standard limit is generally 30% of the maximum exclusion, figured on a daily basis, and the Form 2555 instructions list higher limits for high-cost localities. If you choose the housing exclusion, you must figure it before the earned income exclusion.

An unused housing deduction can be carried to the next year only. The exclusion itself does not carry over.

Understand how the foreign tax credit is limited

The IRS says only foreign income, war profits and excess profits taxes generally qualify. The credit is capped at the part of your total US tax that is in proportion to your foreign-source taxable income compared with all taxable income. It also cannot exceed your actual foreign tax liability.

Publication 54 says the limit is figured separately for categories of income, including section 951A category income, foreign branch category income, passive category income, general category income, section 901(j) income, certain income re-sourced by treaty and certain lump-sum distributions. Excluded income is left out when you figure taxable income in each category.

Foreign tax not allowed because of the limit can be carried back 1 year and carried forward 10 years. Schedule B (Form 1116) reconciles carryovers.

There is a narrow exemption from Form 1116. Publication 54 says you can skip the form and the limit if your only foreign-source income is passive income reported on a payee statement, your qualifying foreign taxes are not more than $300 ($600 on a joint return), and you elect this. If you do, unused foreign tax for that year cannot be carried back or forward.

You can also deduct foreign income taxes on Schedule A instead of crediting them, but you must treat all foreign income taxes the same way in a year. The IRS says the credit is more advantageous in most cases, and Publication 54 suggests figuring tax both ways.

Combine the two only on different slices of income

The two tools can appear on the same return, but not on the same income. Publication 54 says you cannot take a credit or deduction for foreign income taxes paid on income you exclude, and it gives a fraction to find the foreign tax allocable to the excluded part when only part of your wages is excluded.

For higher earners, Publication 54 notes you can exclude up to the cap and then take a credit for foreign tax paid on the part of the wage that was not excluded. Income such as interest, dividends or rent is not foreign earned income, so the credit is the only one of the two that can reach it.

Claiming the exclusion also changes the rate on what is left. The IRS says tax on nonexcluded income is figured at the rates that would apply without the exclusion, using the Foreign Earned Income Tax Worksheet in the Form 1040 instructions.

Count what the exclusion costs in other credits

Publication 54 says that if you elect the foreign earned income exclusion or the housing exclusion, or take the housing deduction, you cannot take the additional child tax credit in the same year. It also says that if you elect the exclusion, you do not qualify for the earned income credit for the year.

These credits can be refundable, so for some families the trade-off is a practical question, not only a tax-rate question. A professional can model both versions of the return.

Plan before you stop using the exclusion

Publication 54 says the exclusion election stays in effect for that year and all later years unless you revoke it. You revoke by attaching a statement to the return or amended return for the first year you do not want the exclusion, naming which choice you revoke. The earned income and housing elections are revoked separately.

Revocation can also happen by conduct. Publication 54 says that taking the foreign tax credit, the additional child tax credit or the earned income credit in a later year counts as revoking the prior choice. Having no foreign earned income in a year does not by itself require a revocation.

If you revoke and want the same exclusion again within 5 tax years, you must ask the IRS for approval through a ruling request. The IRS says it charges a fee for these rulings and may consider facts such as a period of residence in the United States, a move to a country with different tax rates, a change in foreign tax law, or a change of employer.

Remember what neither tool settles

Neither tool reduces self-employment tax. Publication 54 says self-employment income counts for net earnings from self-employment even when it is exempt from income tax under the exclusion. A totalization agreement is the separate route to check.

States follow their own rules. California's residency guide says California does not allow a foreign tax credit or a foreign earned income exclusion, while Virginia's residency page says people who qualify under section 911 receive the same exclusion on Virginia returns. See state taxes after moving abroad.

Foreign account reports are separate duties as well. See FBAR vs Form 8938 the broader US citizens abroad guide, and the United States country page.

Common misconceptions

Questions to take to a professional

1. Is my tax home in a foreign country, and does my abode stay outside the United States?
2. Do I meet the bona fide residence test or the physical presence test, and for which 12-month period?
3. Over several years, how do my US tax and refundable credits compare under the exclusion, the credit, and a mix of both?
4. Which foreign tax credit categories does my income fall into, and do I have carryovers from earlier years?
5. Have I made a Form 2555 election in a past year, and would claiming the credit now count as revoking it?
6. Does my housing cost qualify for the housing exclusion or deduction, and is my city on the high-cost list?
7. How does the state I left treat the exclusion and foreign taxes?
