Critical Notes for Expats
The automatic 2-month filing extension to June 15 for expats does NOT extend the payment deadline. Tax owed must be paid by April 15 or interest (currently ~8% annualised) accrues from April 15.
Unlike the tax return, the FBAR (FinCEN 114) automatically extends to October 15 for all filers — no need to request the extension. However, the underlying accounts must still be reported accurately.
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.
