Critical Notes for Expats
June 15 Extension Is Usually a Filing Extension
The automatic 2-month extension helps expats file later, but tax payments are still expected by the regular April deadline to reduce interest and penalties.
FBAR Auto-Extended to October 15
FinCEN grants an automatic FBAR extension to October 15. No separate extension request is required.
Year-End Strategy
Before year-end: maximise retirement contributions (SEP-IRA / Solo 401k), harvest capital losses to offset gains, review foreign account balances for FBAR/FATCA thresholds, pay any estimated Q4 taxes early to ensure they post before Jan 15 bank holiday.
