TL;DR — Key Takeaways
- →FBAR (FinCEN Form 114) is a Bank Secrecy Act report, filed separately from the income-tax return.
- →The trigger used on this site is more than $10,000 aggregate across foreign accounts at any point in the year.
- →The calendar due date is 15 April, with an automatic extension to 15 October when required.
- →Form 8938 (FATCA) is a different form that rides with the return. Missing FBAR is a reporting gap, not a tax you already paid by filing.
Short answer
Filing your US income-tax return does not file the FBAR. FinCEN Form 114 is a separate report. People discover the gap years later because the IRS accepted the 1040.
What was missed
US persons whose foreign financial accounts exceeded $10,000 in aggregate at any point in the year may need to report those accounts on the FBAR. "Aggregate" means the high-water mark across accounts, not the year-end balance of one bank.
On this site's compliance calendar, FBAR is due 15 April with an automatic extension to 15 October when required. It is not an attachment to Form 1040.
Form 8938 is the FATCA information return that does go with the tax return, at higher thresholds. You can owe one, the other, or both. Filing one is not filing the other.
If the returns went in and the FBAR did not
The income may already be on the 1040 while the account report is absent. That is a reporting miss, not evidence that no report was required. The IRS describes specific correction procedures for people who reported the income and only missed the FBAR — which procedure fits depends on whether you were already contacted and on the rest of the facts. A CPA who handles foreign-account reports should choose the path. Do not treat a quiet year as a closed year once you know the form was skipped. Penalties for non-filing can be severe.
