2026 U.S. Expat Tax Guide: 2025 Deadlines, FBAR, FEIE, and Form 8938

If you are a U.S. citizen or green card holder living abroad, the IRS still requires you to file a tax return in 2026 for the 2025 tax year. Unlike most countries, the U.S. taxes its citizens on worldwide income, regardless of where they live or where the money was earned.

A common misconception is that paying local taxes abroad exempts you from U.S. filing. In reality, you must still file a return and report your foreign accounts. However, you can often use tax breaks like the Foreign Earned Income Exclusion (FEIE) or the Foreign Tax Credit (FTC) to reduce or even eliminate your U.S. tax bill.

Deadline Type

Date

Note

Tax Payment Due

Interest starts accruing after this date.

Expat Filing Deadline

June 15, 2026

Extended Deadline

October 15, 2026

Requires filing Form 4868 by June 15.

FBAR Deadline

October 15, 2026

Important Note: While your filing deadline is automatically extended to June 15, any tax owed is still due by April 15. The IRS will charge interest on unpaid balances from April 15 onward.

For the 2025 tax year (returns filed in 2026), you generally must file a return if your gross income exceeds these standard deduction thresholds:

Filing Status (Under Age 65)

Gross Income Threshold

Single

$15,750

Married Filing Jointly

$31,500

Head of Household

$23,625

Married Filing Separately

$5

Qualifying Surviving Spouse

$31,500

Self-Employed? The threshold is much lower. You must file a U.S. return if your net earnings from self-employment were $400 or more, even if you live entirely outside the U.S.

This is a risky mistake. Tax benefits like the Foreign Earned Income Exclusion and the Foreign Tax Credit are not automatic; you must claim them by filing a tax return.

For the 2025 tax year, the maximum FEIE limit is $130,000 per person. If you and your spouse both work abroad and file jointly, you could potentially exclude up to $260,000 of earned income.

The foundation of your filing. This is where you report your worldwide income, including wages, interest, dividends, and rental income from any country.

You must file an FBAR if the total value of all your foreign financial accounts (bank accounts, brokerage accounts, etc.) exceeded $10,000 at any point during 2025.

• Tip: This is filed with the Treasury Department (FinCEN), not the IRS.

Unlike the FBAR, Form 8938 is filed with your tax return. It has higher thresholds for those living abroad:

• Single/MFS: Over $200,000 on the last day of 2025 or $300,000 at any time during the year.
• Married Filing Jointly: Over $400,000 on the last day of 2025 or $600,000 at any time during the year.

Used to exclude your foreign salary or self-employment income from U.S. tax. To qualify, you must pass either the Bona Fide Residence Test or the Physical Presence Test (330 full days abroad).

Managing U.S. tax compliance while living abroad is complex. You have to track foreign accounts in one place and organize cross-border financial data across multiple currencies and jurisdictions.

Aequify simplifies this by helping you prepare tax-ready information that can be shared with an independent tax professional. While Aequify does not provide tax or legal advice, we ensure your data is structured so you never miss a threshold.

1. Do U.S. expats get an automatic filing extension?

Yes. Many U.S. citizens and residents living abroad get an automatic 2-month extension to file, which moves the filing deadline to June 15, 2026 for 2025 returns. You should attach a statement explaining why you qualify. Interest on unpaid tax still generally starts from the regular due date.

2. What is the FBAR deadline for 2026?

The FBAR is due April 15, 2026, and there is an automatic extension to October 15, 2026. You do not need to request that extension separately.

3. What is the FEIE limit for 2025?

For tax year 2025, the maximum Foreign Earned Income Exclusion is $130,000 per qualifying person.

4. What is the Form 8938 threshold for expats?

For many expats living abroad, Form 8938 starts at more than $200,000 on the last day of the year or more than $300,000 at any time during the year for single filers or married filing separately. For married filing jointly abroad, the thresholds are generally more than $400,000 on the last day of the year or more than $600,000 at any time during the year.

5. Do I still need to file if I already pay tax abroad?

Often yes. The U.S. taxes citizens and residents on worldwide income. You may still need to file a return even if tax credits or exclusions later reduce your U.S. tax bill.
