Substantial Foreign Account Reporting (200K+)

Foreign accounts exceeding $200,000 trigger the full suite of reporting requirements and the highest penalty exposure. At this asset level, PFIC complications, multiple reporting forms, and professional CPA guidance become non-negotiable.

Both FBAR and FATCA are mandatory. You must file FinCEN Form 114 (FBAR) for accounts exceeding $10,000 aggregate, and Form 8938 (FATCA) for foreign financial assets above the applicable threshold. These are separate filings with separate penalties, and the information reported overlaps but is not identical.

Multiple forms may be required. Beyond FBAR and Form 8938, accounts at this level often involve Form 8621 (PFIC reporting for foreign mutual funds), Forms 3520/3520-A (foreign trust reporting for certain pension plans), and Form 1116 (Foreign Tax Credit). Each form has its own penalty regime for non-filing.

Interest, dividends, and capital gains reporting. Income earned in foreign accounts is fully taxable on your US return. Foreign banks may not issue 1099 equivalents, so your CPA must obtain account statements and calculate reportable income, including unrealized gains on PFIC holdings if a mark-to-market election is in place.

PFIC rules catch foreign mutual funds. If any portion of your foreign accounts includes mutual funds, ETFs, or investment vehicles organized outside the US, they are almost certainly classified as PFICs. The default "excess distribution" regime imposes tax at the highest marginal rate plus an interest charge. QEF or mark-to-market elections can mitigate this but require annual compliance.

The tradeoff: At this asset level, international tax compliance is expensive but non-optional. CPA fees for proper reporting may run several thousand dollars annually, but FBAR penalties alone can exceed the total account value if violations are found to be willful.
