U.S. taxpayer files the tax return and Form 8938 but forgets the separate FBAR filing

A U.S. person with foreign accounts assumes the return package solved the disclosure problem, then learns that the Treasury-side reporting obligation runs on a different track.

The situation

A U.S. citizen living in Singapore keeps several foreign bank and brokerage accounts, gives the annual account figures to a preparer, and feels relieved after the federal tax return is filed with Form 8938 attached. Months later, the taxpayer hears someone mention the FBAR and realises nobody ever filed anything through FinCEN.

What matters first

The IRS is clear that Form 8938 and the FBAR are not the same filing. The FBAR is a Treasury reporting obligation filed electronically through FinCEN, while Form 8938 is filed with the federal income tax return if its own thresholds are met. That means the taxpayer's first mistake was assuming one disclosure system automatically satisfied the other.

Why the confusion happens so often

The facts overlap just enough to create false confidence. Both regimes can involve foreign accounts or foreign financial assets, and both are discussed in international-tax conversations. But the IRS comparison page exists precisely because taxpayers keep conflating them. Once that happens, the return can be filed cleanly and the separate Treasury filing can still be missing.

What the next step should look like

The taxpayer needs to reconstruct the annual maximum balances for the relevant foreign accounts, test the FBAR threshold separately and treat the missing filing as its own compliance problem. The better long-term fix is procedural: every year, foreign-account reporting should be checked under both systems instead of being lumped into a single mental box labeled 'international disclosure.'

Action checklist

  • 1Test the FBAR obligation separately from the Form 8938 obligation.
  • 2Reconstruct annual maximum foreign-account balances rather than relying only on year-end statements.
  • 3Do not assume a tax-return attachment automatically solved the Treasury-side filing duty.
  • 4Build a yearly foreign-account checklist that includes both filing systems.
