Why International Tax Matters for EAs
The United States taxes its citizens and resident aliens on worldwide income, regardless of where that income is earned. This means an American software engineer working in Berlin, a dual citizen receiving rental income from property in Toronto, or a small business owner with overseas suppliers all face international tax obligations.
As an Enrolled Agent, you will encounter clients with cross-border tax situations more frequently than you might expect. The EA exam tests your understanding of the key international provisions, and this guide covers the concepts most likely to appear on Parts 1 and 2 of the SEE.
FATCA: The Foreign Account Tax Compliance Act
FATCA, enacted in 2010, is the cornerstone of the U.S. government's effort to combat offshore tax evasion. It operates on two levels:
Institutional Requirements
FATCA requires foreign financial institutions (FFIs) — banks, investment firms, insurance companies, and pension funds outside the United States — to report information about accounts held by U.S. persons to the IRS. Institutions that fail to comply face a 30% withholding tax on certain U.S.-source payments.
This means that if a U.S. taxpayer opens a brokerage account in Singapore, the Singaporean brokerage is obligated to report that account to the IRS. The practical effect is that hiding foreign accounts from the IRS has become extremely difficult.
Individual Reporting: Form 8938
U.S. taxpayers with foreign financial assets above certain thresholds must file Form 8938 (Statement of Specified Foreign Financial Assets) with their annual tax return. The thresholds depend on filing status and whether the taxpayer lives in the U.S. or abroad:
| Filing Status | Living in U.S. | Living Abroad |
|---|---|---|
| Single | $50,000 year-end / $75,000 any time during year | $200,000 year-end / $300,000 any time |
| Married Filing Jointly | $100,000 year-end / $150,000 any time | $400,000 year-end / $600,000 any time |
Specified foreign financial assets include bank accounts, investment accounts, foreign stocks and securities held outside a U.S. financial institution, interests in foreign entities, and foreign-issued life insurance or annuity contracts with cash value.
For example, consider Marcus, a single taxpayer living in Chicago who holds a savings account at a bank in Frankfurt worth $38,000 and a brokerage account in London worth $22,000. His combined foreign assets of $60,000 exceed the $50,000 year-end threshold for single filers in the U.S., so he must file Form 8938.
FBAR: Report of Foreign Bank and Financial Accounts
The FBAR (FinCEN Form 114) is a separate reporting requirement from FATCA, administered by the Financial Crimes Enforcement Network (FinCEN) rather than the IRS. Any U.S. person with a financial interest in or signature authority over foreign financial accounts must file an FBAR if the aggregate value of all foreign accounts exceeds $10,000 at any point during the calendar year.
Key Differences Between FBAR and FATCA Form 8938
| Feature | FBAR (FinCEN 114) | FATCA (Form 8938) |
|---|---|---|
| Filing threshold | $10,000 aggregate at any time | Varies by filing status and residence |
| Where to file | Electronically via FinCEN BSA E-Filing | Attached to annual tax return |
| Due date | April 15, with automatic extension to October 15 | Same as tax return (April 15 or extension) |
| Penalties for non-filing | Up to $16,117 per violation (non-willful); $100,000 or 50% of account balance (willful) | $10,000 per failure to disclose; up to $60,000 for continued failure |
| Accounts covered | Bank accounts, securities accounts, mutual funds, certain insurance policies | Broader: includes foreign stocks, partnership interests, financial instruments |
A critical exam point: FBAR and Form 8938 have different thresholds and cover overlapping but not identical assets. A taxpayer may need to file both, one, or neither depending on their specific situation. Filing one does not exempt you from filing the other.
Tax Treaties: Preventing Double Taxation
The United States has income tax treaties with approximately 65 countries. These treaties serve two primary purposes: preventing the same income from being taxed by both countries, and providing mechanisms for resolving disputes between tax authorities.
How Treaties Reduce Tax
Treaties typically reduce or eliminate withholding tax on cross-border payments such as dividends, interest, and royalties. Without a treaty, the default U.S. withholding rate on dividends paid to foreign persons is 30%. Many treaties reduce this to 15% or even 5% for qualifying corporate shareholders.
For example, under the U.S.-United Kingdom treaty, dividends paid by a U.S. company to a qualifying U.K. resident are subject to a maximum withholding rate of 15% instead of the statutory 30%. If a U.K. investor receives $10,000 in dividends from a U.S. stock, the withholding is $1,500 rather than $3,000.
Treaty Tie-Breaker Rules
When a taxpayer could be considered a resident of both countries under their respective domestic laws, treaties include tie-breaker rules to assign residency to one country. The typical hierarchy examines: permanent home, center of vital interests (personal and economic ties), habitual abode, and finally nationality.
The Savings Clause
U.S. tax treaties contain a savings clause that preserves the right of the United States to tax its own citizens and residents as if the treaty did not exist. This means that a U.S. citizen living in France cannot use the U.S.-France treaty to reduce tax on income that the U.S. has the right to tax under its domestic law. The savings clause has limited exceptions, primarily for certain government pensions and social security benefits.
The Foreign Tax Credit
The foreign tax credit (FTC) is the primary mechanism for preventing double taxation of U.S. persons earning income abroad. It allows taxpayers to reduce their U.S. tax liability dollar-for-dollar by the amount of income taxes paid to foreign governments.
How It Works
Sarah, a U.S. citizen, earns $80,000 in consulting income from clients in Japan. Japan withholds $16,000 in income tax. On her U.S. return, Sarah reports the full $80,000 as income and computes her U.S. tax on it. She then claims a foreign tax credit of up to $16,000 against her U.S. tax liability.
The credit is limited to the U.S. tax attributable to the foreign-source income. If Sarah's effective U.S. rate on that income would be 20% ($16,000), the credit fully offsets her U.S. tax. If her U.S. rate is only 15% ($12,000), she can credit $12,000 currently and carry the excess $4,000 forward for up to ten years (or back one year).
Credit vs. Deduction
Taxpayers can elect to deduct foreign taxes paid instead of claiming a credit. However, a credit is almost always more advantageous because it reduces tax liability dollar-for-dollar, while a deduction only reduces taxable income. A $10,000 credit saves $10,000 in tax; a $10,000 deduction for a taxpayer in the 24% bracket saves only $2,400.
Foreign Earned Income Exclusion
The Foreign Earned Income Exclusion (FEIE), claimed on Form 2555, allows qualifying U.S. citizens and resident aliens living abroad to exclude a portion of their foreign earned income from U.S. taxation. For tax year 2025, the maximum exclusion is approximately $130,000 (adjusted annually for inflation).
Qualifying Tests
To claim the FEIE, you must meet one of two tests:
- Bona Fide Residence Test — You must be a bona fide resident of a foreign country for an uninterrupted period that includes an entire tax year. Brief trips back to the U.S. do not necessarily break bona fide residence.
- Physical Presence Test — You must be physically present in a foreign country or countries for at least 330 full days during any 12-month period. The 330 days need not be consecutive, but each day must be a full 24-hour period.
Housing Exclusion
In addition to the income exclusion, qualifying taxpayers can exclude or deduct certain foreign housing expenses that exceed a base amount (16% of the FEIE limit). This covers reasonable expenses such as rent, utilities, and insurance for a foreign residence, but not lavish or extravagant expenses.
FEIE vs. Foreign Tax Credit
Taxpayers cannot claim the foreign tax credit on income excluded under the FEIE. If you earn $150,000 abroad and exclude $130,000 under the FEIE, you can only claim foreign tax credits on the remaining $20,000 of taxable foreign income. Choosing between the FEIE and FTC (or using both strategically) depends on the tax rates in the foreign country, the level of income, and the taxpayer's overall tax situation.
Exam Strategy for International Tax Questions
International tax questions on the EA exam tend to focus on:
- Identifying who must file FBAR and Form 8938 based on account values and filing status
- Calculating the foreign tax credit limitation
- Determining eligibility for the FEIE under the bona fide residence or physical presence test
- Understanding the basic mechanics of tax treaties (reduced withholding rates, tie-breaker rules)
The exam tests application, not memorization. Practice with scenarios involving specific dollar amounts, dates, and taxpayer circumstances to build the pattern recognition needed for exam day.
