Six Years of Unreported Foreign Business Ownership — and the Path Back to Full Compliance
How we used the IRS Streamlined Domestic Offshore Procedures to resolve an unfiled-Form-5471 case involving a foreign manufacturing company, twenty-two foreign accounts, and a six-year cleanup — while containing the penalty to a single, predictable number.

The situation
A married couple in the Chicago suburbs came to us for what they thought was a routine tax year. One spouse is a U.S. citizen with ordinary W-2 wages. The other, a Korean-born entrepreneur, became a U.S. tax resident a few years ago — and owns 95% of an active manufacturing company in Vietnam, along with personal bank accounts in Korea and Vietnam.
None of that had ever been reported. Not because anyone was hiding it — but because no one had ever asked. The original returns were prepared by two different firms over the years, and neither ever raised foreign accounts or foreign companies. When the client heard from an acquaintance that there might be filing obligations, she went back to her preparer and asked them to fix it. They filed amendments that picked up some of the foreign income… and still missed the most important forms entirely.
An amended return is not the same thing as compliance. The 2024 amendments reported income — but no Form 5471 for the corporation, an incomplete Form 8938, and no analysis of the U.S. anti-deferral rules that apply to foreign companies. The client reasonably believed she was fixed. She wasn't.
When we reviewed the file, the exposure was serious: Form 5471 carries an automatic $10,000 penalty per form, per year. Form 8938 and FBAR penalties stack on top. Six years of that, across an operating company and dozens of accounts, adds up quickly — before anyone even discusses the income tax itself.
The strategy
The IRS Streamlined Domestic Offshore Procedures exist for exactly this situation: a taxpayer whose failure to report foreign assets was non-willful. In exchange for three years of amended returns, six years of FBARs, a sworn certification (Form 14654), and a single miscellaneous offshore penalty of 5% of the highest year-end value of the affected foreign assets, the IRS agrees not to assert the per-form information return penalties that would otherwise apply.
We filed the three streamlined years through the program, filed the earlier years as voluntary corrections alongside it, and rebuilt every number from primary sources so the entire six-year story is consistent from the first page to the last.
What made this case genuinely hard
- Establishing the residency start dateThe foreign spouse arrived in the U.S. in late one year, married a U.S. citizen days into the next, and received a green card a year after that. Which year was her first U.S. tax year? We built the substantial-presence analysis to pin residency to the earliest defensible date — because every later conclusion (which years get amended, which years get FBARs, what goes in the penalty base) depends on it.
- Rebuilding a foreign company's books in U.S. termsThe Vietnamese company keeps audited financial statements in Vietnamese dong, under Vietnamese accounting standards. Six years of Form 5471 balance sheets, income statements, and earnings-and-profits computations had to be rebuilt from those statements — down to details like sourcing fixed-asset balances from the audited movement notes rather than the depreciation register, which silently omits fully-depreciated assets still in use.
- The anti-deferral gauntlet: GILTI and Subpart FA U.S. person who controls a foreign corporation may owe U.S. tax on the company's earnings even if nothing is distributed. We computed the GILTI inclusion for every year — and documented why, in several years, the inclusion was zero because the company's tangible asset base (the deemed tangible income return) exceeded its tested income. Showing zero with full workpapers is very different from ignoring the rules.
- Wages reported net of foreign taxThe original returns reported the foreign salary net of Vietnamese income tax withheld — understating wages and forfeiting the credit. We re-grossed the compensation for every year and claimed the Vietnamese tax as a foreign tax credit instead, which changes adjusted gross income, the tax, and the credit simultaneously.
- A six-year foreign tax credit chain, rebuilt to the dollarForeign tax credit carryovers flow from year to year, in separate limitation baskets, with a parallel AMT computation. Amending all six years at once means the carryover schedules on every return must chain perfectly — we reconstructed the entire chain, regular and AMT, and closed it to a documented zero endpoint so no phantom carryover surfaces on a future return.
- Untangling corporate and personal accountsThe earlier amendment had reported the company's bank accounts as the client's personal accounts. We separated them: corporate accounts belong on the company's Form 5471 and in the FBAR signature-authority analysis; the personal accounts and the equity interest itself belong on Form 8938. Getting this wrong overstates some disclosures and understates others.
- Computing the 5% penalty base defensiblyThe streamlined penalty is 5% of the highest aggregate year-end value of the affected assets. That meant valuing 22 accounts and assets at each of six year-ends, in three currencies, at U.S. Treasury year-end exchange rates — with documented methods where statements were incomplete, and a stated, consistent valuation for the company equity itself. The highest year, not the total, sets the penalty; the workpapers have to survive scrutiny of both.
- The non-willfulness narrativeThe certification is a sworn statement, signed under penalties of perjury, telling the IRS exactly why the failures happened. It has to be complete, accurate, and consistent with every fact in the returns — including the uncomfortable history of two prior preparers and a first amendment attempt that didn't finish the job. We drafted it with separate statements for each spouse, as the form requires when their reasons differ.
- Assembly is part of the law hereStreamlined submissions have strict mechanics: the words “Streamlined Domestic Offshore” in red ink on every return, the certification original plus a copy attached to each return, wet signatures, one envelope, no staples, a specific IRS unit in Austin — and the state returns sequenced separately, only where money actually moves. A perfect technical filing can still fail on assembly.
The outcome
| Exposure without the program | Result under the streamlined procedures |
|---|
| $10,000 per unfiled Form 5471, per year — six figures before any other penalty | No information-return penalties asserted |
| Form 8938 and FBAR penalties, potentially per account, per year | Resolved within the same submission |
| Open-ended examination risk across every year | One 5% miscellaneous offshore penalty, computed once, on a documented base |
| Unquantifiable | A single, known, final number — and six years of clean, consistent filings |
The clients mailed their submission knowing the exact cost of the cleanup, with every figure tied from primary documents to the printed returns, and with instruction letters that told them precisely where to sign and what to mail. The hardest part of a case like this is not any single computation — it is making six years of federal returns, state returns, information returns, FBARs, and a sworn certification tell exactly one story.
What this case teaches
If your preparer has never asked you about foreign accounts or foreign companies, that is a red flag — the obligation to report exists whether or not anyone asks. An amendment that reports income is not the same as compliance — the information returns (5471, 8938, FBAR) carry their own, separate penalties. And the streamlined programs reward acting before the IRS finds you — eligibility depends on non-willfulness and on coming forward first. The earlier the problem is found, the more options exist for solving it.
