2025 Tax Deadlines for US Expats
At KKCA, we understand that living abroad brings unique financial complexities. For US citizens and Green Card holders residing overseas, the tax calendar isn’t just a suggestion—it’s a roadmap to protecting your wealth and maintaining compliance.
As we move through 2025, here is your definitive guide to the dates and thresholds you need to know for your 2025 tax year filings (due in 2026).
1. The 2025-2026 Filing Calendar
While those in the States are rushing for April 15, expats have a slightly different rhythm. However, a common misconception is that the extension applies to payments. It does not.
April 15, 2026: The Payment Deadline
Regardless of where you live, any tax owed to the IRS for the 2025 calendar year must be paid by this date to avoid interest charges.
June 15, 2026: The Automatic Expat Extension
US citizens and residents living and working outside the US and Puerto Rico receive an automatic two-month extension to file their federal income tax return.
- Action: You don’t need to file a form for this, but you must attach a statement to your return explaining your eligibility.
October 15, 2026: The Final Extension
If you need more time beyond June, you can file Form 4868 to extend your filing deadline to October 15.
2. Foreign Asset Reporting: FBAR & FATCA
International compliance is the IRS’s top priority. Missing these forms can lead to penalties that far outweigh the tax itself.
The FBAR (FinCEN Form 114)
If the total value of your foreign financial accounts exceeded $10,000 at any point during 2025, you must file an FBAR.
- Deadline: April 15, 2026 (with an automatic extension to October 15).
Form 8938 (FATCA) Thresholds
Unlike the FBAR, Form 8938 is filed directly with your Form 1040. The thresholds for taxpayers living abroad are significantly higher:
| Filing Status | Assets at Year-End (Dec 31) | OR | Assets at Any Peak Point |
|---|---|---|---|
| Single / MFS | Over $200,000 | Over $300,000 | |
| Married Filing Jointly | Over $400,000 | Over $600,000 |
Note: If you live in the US, these thresholds drop to $50,000 / $75,000 respectively.
3. Quarterly Estimated Tax Payments
For our self-employed clients or those with significant investment income, 2025 estimated taxes should be paid on the following schedule:
- 1st Payment: April 15, 2025
- 2nd Payment: June 16, 2025
- 3rd Payment: September 15, 2025
- 4th Payment: January 15, 2026
4. Why Compliance Matters
The IRS continues to expand its reach through data-sharing agreements with foreign banks. Filing Form 2555 (Foreign Earned Income Exclusion) or Form 1116 (Foreign Tax Credit) correctly is the difference between double taxation and a $0 tax bill.
The KKCA Difference: We don’t just file forms; we strategize. Whether you are navigating the Foreign Housing Exclusion or complex PFIC reporting for foreign mutual funds, we ensure your global footprint is optimized.
Stay Ahead of the Clock
Tax laws for expats are in a constant state of flux. Don’t wait until June to realize you have a reporting requirement.
