Late FBAR & FATCA Filing — What Are Your Options?
FBAR · FATCA 미신고 해결 방법 — 4가지 경로 완전 해설 2026

Does This Apply to FATCA (Form 8938) Too? FATCA 미신고에도 동일하게 적용되나요?

Yes — and the good news is that all four compliance pathways cover both FBAR and FATCA simultaneously. When you use any of the IRS programs to correct past non-compliance, Form 8938 (FATCA) is handled alongside the FBAR — they are not treated as separate remediation tracks.

FATCA Penalties (Form 8938) — Also Being Avoided

• $10,000 initial penalty per year for failure to file Form 8938 when required
• $10,000 per 30-day period after IRS notice(up to $50,000 additional) for continued failure after IRS notification
• 40% accuracy-related penalty on any U.S. tax underpayment attributable to undisclosed foreign financial assets (double the standard 20% accuracy penalty)
• All of these FATCA penalties are waived under SFOP; a 5% miscellaneous offshore penalty replaces them under SDOP

Willfulness — How IRS Decides 의도적 여부 판단 기준

The willful vs. non-willful determination is the single most consequential decision in an FBAR compliance situation. It determines whether the taxpayer is eligible for the far more favorable streamlined and DFSP procedures — or must use the VDP with substantially higher penalties.

Reasonable Cause Defense 합리적 이유 항변

Beyond the four formal programs, the IRS can waive FBAR penalties on a case-by-case basis when the taxpayer demonstrates "reasonable cause" for the failure and shows that the failure was not due to willful neglect. Reasonable cause is not a formal program — it is a legal defense submitted with the late FBAR filings or as a response to an IRS assessment.

What Constitutes Reasonable Cause for Korean FBAR Filers

• First-year U.S. resident with no prior awareness: A Korean national who became a U.S. tax resident for the first time and had no knowledge of the FBAR requirement — particularly one who had not been advised by a CPA familiar with cross-border compliance — has a strong reasonable cause argument. The complexity of U.S. cross-border rules, combined with the abrupt change in tax status, supports a good-faith misunderstanding defense.
• Language barrier: Korean-language documentation of the FBAR obligation is not readily available from the IRS or standard U.S. tax resources. A Korean-speaking taxpayer who relied on Korean-language sources or a Korean-language CPA who was unfamiliar with FBAR may have a language-barrier-based reasonable cause argument.
• Reliance on a tax professional: If a U.S. CPA or tax preparer was hired and failed to ask about or disclose Korean foreign accounts, the taxpayer may argue reasonable cause based on reasonable reliance on a professional. The taxpayer must show they disclosed the accounts to the professional and that the professional's failure to advise on FBAR was the cause of non-compliance.
• Substantiate the cause in writing: Reasonable cause is not established by simply claiming it — it requires a specific written narrative explaining: what the taxpayer knew and when; what steps they took to comply; why they reasonably believed no filing was required; and what they did to correct the situation once the obligation was discovered.

Common Mistakes 자주 발생하는 오류

• 1 Filing a streamlined submission with a willful situation. The non-willfulness certification on Forms 14653 (SFOP) and 14654 (SDOP) is signed under penalty of perjury. Filing streamlined while the actual conduct was willful — or even recklessly disregardful — is itself a criminal act (filing a false statement to the U.S. government). If there is any genuine uncertainty about willfulness (e.g., Schedule B was checked "No"), consult a CPA before filing anything. A wrong choice of program compounds the problem significantly.
• 2 Using the original document's $10,000 non-willful penalty figure for risk calculation. The 2026 non-willful FBAR penalty is $16,536 per annual FBAR form (Bittner — per form, not per account). The original document cites $10,000 per violation. While Bittner generally makes non-willful exposure more manageable (one penalty per year, not per account), the per-form amount is higher than the statutory base. Risk calculations based on the old $10,000 figure understate exposure for each year of non-compliance.
• 3 Waiting for IRS contact before filing late FBARs. Once the IRS contacts the taxpayer about specific foreign accounts — which may happen automatically through FATCA IGA data matching from Korean banks — the streamlined procedures and DFSP become unavailable. The taxpayer loses access to the most favorable penalty outcomes simply by waiting. Proactive filing before any IRS contact preserves all options.
• 4 Filing late FBARs without choosing the correct program — or without filing them at all. Simply filing late FBARs without going through a formal program or providing a reasonable cause statement does not guarantee penalty relief. The DFSP is the correct vehicle for non-willful late FBAR filings where income was reported — it provides the structure (written explanation, FinCEN submission) that positions the taxpayer for penalty waiver. Filing late FBARs without any accompanying explanation or program participation may still result in a penalty assessment.
• 5 Not including Form 8938 in the streamlined submission package. Taxpayers who use SFOP or SDOP to address missed FBARs sometimes overlook the simultaneous requirement to include Form 8938 on the amended tax returns. If Form 8938 was required but not filed in prior years (because foreign assets exceeded the FATCA thresholds), it must be included on the corresponding amended returns that are part of the SFOP/SDOP package. An incomplete package that corrects FBAR but misses Form 8938 leaves the FATCA compliance gap open.
• 6 Using SFOP when the taxpayer does not meet the 330-day abroad test. SFOP requires the taxpayer to have been present outside the U.S. for at least 330 full days in at least one of the 3 most recent tax years. A Korean-American who has been living in the U.S. but visited Korea frequently does not qualify for SFOP — even if they have significant Korean assets. Such a taxpayer must use SDOP (5% penalty) rather than SFOP (0%). Incorrectly using SFOP when SDOP applies can result in the IRS rejecting the submission entirely.
• 7 Not documenting the non-willfulness narrative in sufficient detail. The non-willfulness certification (Form 14653 or 14654) requires a specific, credible narrative explaining why the taxpayer failed to file. A generic statement ("I didn't know about FBAR") is less effective than a detailed, specific narrative: "I immigrated to the United States on [date] and became a U.S. tax resident for the first time. I used a Korean-speaking tax preparer who was unfamiliar with the FBAR requirement. My Korean bank accounts had been held since [date] in connection with [specific purpose]. I had no intention of concealing these accounts from the U.S. government." The more specific and credible the narrative, the stronger the reasonable cause position.
• 8 Not addressing Form 8621 (PFIC) in the streamlined package when Korean ETFs or mutual funds were held. Taxpayers who held Korean domestic ETFs or mutual funds during the non-compliance period may also have Form 8621 filing obligations. SFOP and SDOP waive the Form 8621 information return penalties — but the underlying PFIC tax calculations may still produce additional tax liability that must be included on the amended returns. A streamlined package that corrects FBAR and Form 8938 but misses Form 8621 for Korean ETFs is incomplete and may be rejected or subject to additional scrutiny.
