Behind on US filings? What streamlined compliance actually involves

You are a US citizen or green card holder living abroad. You have not filed a US return in years, three, seven, fifteen. You either did not know the obligation existed, or you knew and could not face it, and every year that passed made starting harder.

Two things are true and they point in the same direction.

Your exposure is probably far larger than you think, because it sits in information returns rather than tax. And it is probably fixable with the penalties waived entirely, provided you go first.

Most Americans abroad owe little or no US income tax once the foreign earned income exclusion and the foreign tax credit are applied properly. People assume that means little exposure.

It does not, because the penalties attach to the filings, not to the tax.

• A missed Form 5471 for a foreign company: $10,000 per company, per year.
• FBAR failures: penalties per violation, escalating sharply where conduct is treated as willful.
• Form 3520 for foreign gifts and trusts: penalties measured as a percentage of the amount.
• Unreported PFICs: no flat penalty, but the statute of limitations never closes and the interest charge compounds.

Someone with two foreign companies and six unfiled years can be looking at six figures of information return exposure while owing essentially nothing in tax. That asymmetry is the single most important thing to understand about this situation.

The IRS operates a route for taxpayers whose failure to file was nonwillful, negligence, inadvertence, mistake, or a good faith misunderstanding of the law.

For taxpayers who meet the nonresidency requirement, the offshore version waives the penalties entirely. You file, you pay whatever tax and interest is actually due, and the penalties that would otherwise apply are not asserted.

There is a parallel domestic version for people living in the US, which carries a miscellaneous offshore penalty calculated on the highest aggregate value of the unreported foreign assets. Meaningfully worse, and still far better than the alternative.

Everything rests on one document: a signed statement, under penalties of perjury, setting out the specific facts and circumstances explaining why the failures were nonwillful.

Not a form to tick. A narrative. Why you did not know, what you understood at the time, who advised you and what they said, when and how you found out, and what you did once you knew.

This is where submissions succeed or fail. A generic paragraph saying you were unaware of the requirement is weak and invites scrutiny. A specific, honest, verifiable account, you left the US at twenty three, you filed and paid taxes diligently in your country of residence, no advisor ever raised US filing, you learned of it from a bank asking about your citizenship in 2024, is credible because it is checkable and because it is what actually happened.

Two warnings. The certification is signed under penalty of perjury. If the facts do not honestly support nonwillfulness, if you were told and ignored it, if you moved money to avoid detection, if you deliberately structured around reporting, this is the wrong programme and using it makes your position considerably worse. That situation needs a lawyer, not an accountant.

And do not draft it as an afterthought once the returns are done. It is the primary document. The returns support it.

The standard description, three years of returns, six years of FBARs, describes the straightforward case: an employee abroad with a salary and a couple of bank accounts.

If you own anything, the returns are the easy part. The work is in the information returns that hang off them:

• Form 5471 for each foreign company, for each year, which requires the company’s financial statements restated to US standards. If your books are in local format under local rules, that is a reconstruction project.
• Form 8621 for each PFIC, which for most non US mutual funds and ETFs means identifying holdings, computing under the excess distribution rules, and considering whether an election is available.
• Form 3520 and 3520-A where there is a foreign trust, an inheritance, or a large gift from abroad.
• Form 8938 alongside the FBAR, on different thresholds, capturing assets rather than only accounts.

The accounting is the bulk of the cost and the bulk of the elapsed time. Anyone quoting you a fixed low fee without having asked what you own has not understood your situation.

There is no filing deadline for a streamlined submission. There is something more important: the programme is unavailable once the IRS has initiated a civil examination or a criminal investigation.

Coming forward is voluntary only while you are first. And you are increasingly unlikely to be first, because foreign financial institutions report US account holders under FATCA, and the reason many people discover this problem at all is a letter from their own bank asking about their citizenship.

If your bank has already asked, the clock is running.

• Do not file a single year quietly on its own. A “quiet disclosure”, amending or filing back years outside the programme, forfeits the penalty protection and flags you.
• Establish the facts first: citizenship history, residence history, what you own, what accounts existed, what you were told and when.
• Assess nonwillfulness honestly. If it does not hold, get a lawyer before anything is filed.
• Scope the information returns before agreeing to any fee.
• Prepare the whole package together and submit it as one.

The people who come out of this well are, almost without exception, the ones who moved before they were contacted. The programme exists for exactly your situation. It is not available forever and it is not available afterwards.

If you are behind, a consultation will tell you the actual size of the problem and whether the streamlined route is open to you. Most people find the number is smaller than they feared and the path is clearer than they expected.
