As a U.S. citizen living abroad, managing your expat taxes is essential. You must file a federal income tax return annually, reporting worldwide income—including foreign income—in U.S. dollars. This guide outlines clear steps to comply with your tax obligations, meet expat tax deadlines, minimize your tax liability, and utilize valuable deductions and credits for the 2024 tax year (filed in 2025).
Filing Requirements for US Citizens Abroad
U.S. citizens, resident aliens, and green card holders living abroad are required to file a U.S. tax return if their taxable income exceeds IRS thresholds. Reporting includes all foreign earned income, income from foreign financial assets, and income from foreign trusts.
Income Thresholds for 2024:
- Single filers: $14,700
- Married filing jointly: $29,400
- Self-employed: $400 or more

Expat Tax Deadlines and Due Dates for 2024
For the 2024 tax year, the standard federal income tax return due date is April 15, 2025. U.S. citizens living abroad automatically receive a two-month extension to June 16, 2025 (since June 15 falls on a Sunday). If you need additional time, file Form 4868 by June 16 to extend the filing deadline to October 15, 2025. In certain cases, taxpayers living abroad may request a further discretionary extension to December 15, 2025, by writing to the IRS and explaining the reason for the additional time needed. Extensions do not apply to unpaid taxes; taxes owed must be paid by April 15 to avoid penalties and interest.
Reducing Your Taxes for Expats
Foreign Earned Income Exclusion (FEIE)
The FEIE allows expats to exclude up to $126,500 of foreign earned income from their taxable income for 2024. To qualify:
- Pass the Physical Presence Test (330 days in a foreign country).
- Or meet the Bona Fide Resident Test (full tax year living abroad).
File Form 2555 with your tax return.
Foreign Housing Exclusion or Deduction
Expats who qualify for FEIE may also use the Foreign Housing Exclusion (employees) or Foreign Housing Deduction (self-employed), reducing taxable income by eligible housing expenses such as rent and utilities. Claim this on Form 2555.
Foreign Tax Credit (FTC)
The Foreign Tax Credit helps prevent double taxation by offsetting U.S. income tax with taxes paid to a foreign country. Use Form 1116 to claim FTC. Expats often strategically combine the FTC and FEIE to minimize taxes owed.
Reporting Foreign Financial Accounts and Assets
Expats must report foreign financial accounts and assets via specific forms:
- FBAR (FinCEN Form 114): Required if total foreign financial accounts exceed $10,000 during the calendar year. Due April 15 with an automatic extension to October 15.
- FATCA Form 8938: Required if foreign financial assets exceed certain thresholds ($200,000 for single expats abroad). Non-compliance penalties can reach $50,000.
Child Tax Credit and Additional Child Tax Credit (ACTC)
Americans living abroad qualify for the Child Tax Credit (CTC), reducing taxes up to $2,000 per qualifying child. Importantly, the refundable Additional Child Tax Credit (ACTC) offers a refund of up to $1,700 per child for 2024, even if you owe no taxes. Claim the ACTC on your tax return.
State Income Tax Obligations
Some states require expats to file state tax returns if maintaining significant ties like property, dependents, voter registration, or financial accounts. Verify your state’s specific rules to determine if filing is necessary.

Social Security and Medicare Taxes
Self-employed expats earning $400 or more must pay Social Security and Medicare taxes (15.3% combined). Employees abroad working for U.S. employers may owe 7.65%. Tax treaties between the U.S. and the foreign country clarify these obligations.
Expat Tax Filing Methods
You can file your tax return electronically (e-file) or via mail:
- Use IRS-approved software to e-file.
- Mail returns without payments to the IRS in Austin, TX; returns with payments to Charlotte, NC.
Streamlined Filing Compliance Procedures
If you missed filing taxes previously, utilize the IRS Streamlined Filing Compliance Procedures to catch up. File the last three years of tax returns and six years of FBARs without penalties for failure to file before. This also allows you to retroactively claim exclusions and credits, including FEIE and ACTC.
Tax Implications of Renouncing U.S. Citizenship
Renouncing citizenship triggers significant tax obligations under IRC 877A, especially if you’re classified as a covered expatriate due to net worth or previous tax liability. You must certify tax compliance for five years prior and may face an exit tax.
