Common IRS Audit Red Flags for Americans Living Abroad

Expats Face Additional Reporting Responsibilities
Living abroad does not automatically make a taxpayer more likely to face an audit. However, international returns can contain more forms, income categories, foreign accounts, and currency calculations than a typical domestic return.
U.S. citizens and resident aliens abroad generally must report income from worldwide sources. Failing to include foreign wages, investments, rental income, business income, or retirement distributions can create discrepancies.
Unreported Foreign Income
One of the most significant concerns is income that does not appear on the return. Examples include:
- Foreign salary or freelance income
- Interest from overseas bank accounts
- Foreign dividends and capital gains
- Rental income from foreign property
- Pension or annuity distributions
- Cryptocurrency or digital asset income
- Income from a foreign company or partnership
Foreign income may be reportable even when it is taxed abroad or never transferred to the United States.
Missing FBAR or Form 8938 Filings
Taxpayers may need to file an FBAR, Form 8938, or both. The forms have different thresholds, filing locations, and definitions. Filing one does not replace the other.
A return showing foreign interest or dividends without the related account disclosures may raise questions. International information reporting failures can also carry significant penalties.
Incorrect Foreign Earned Income Exclusion Claims
The Foreign Earned Income Exclusion is not automatic. A taxpayer must have foreign earned income, a foreign tax home, and satisfy either the bona fide residence test or physical presence test.
Under the physical presence test, the taxpayer generally must be present in one or more foreign countries for at least 330 full days within a 12-month period.
Red flags can include:
- Counting partial travel days as full foreign days
- Including time spent in the United States
- Excluding passive or investment income
- Claiming the exclusion without a foreign tax home
- Using inconsistent travel records
Large or Unexplained Foreign Tax Credits
Foreign tax credits can help reduce double taxation, but the credit must be based on eligible foreign income taxes and properly categorized income. A credit that is unusually large compared with reported foreign income may require additional support.
Taxpayers should retain foreign tax returns, payment confirmations, and calculations showing how the credit was determined.
Foreign Businesses and Trusts
Ownership or control of foreign corporations, partnerships, and trusts can trigger forms such as Forms 5471, 8865, 8858, or 3520. The IRS warns that foreign trust reporting failures can result in substantial penalties and may extend the period during which tax can be assessed.
Inconsistent Returns and Records
Differences between a tax return, FBAR, Form 8938, foreign tax return, or information received from a foreign financial institution can invite scrutiny. Consistent reporting and organized documentation are essential.
What to Do If You Receive an Audit Notice
Do not ignore the notice. Review the years and issues listed, gather records, and respond by the stated deadline. Expatriate Tax Returns provides audit assistance for taxpayers facing questions about international income, accounts, credits, and prior filings.
