Every person who discovers they have US filing obligations abroad eventually runs an informal calculation. It usually sounds like this: “A specialist wants over a thousand dollars a year to file paperwork that says I owe nothing. That can’t be worth it.”

That calculation has two numbers in it — and most people only ever look up the first one. This article puts both on the table.

Column A: what compliance actually costs

For a typical American abroad — salary, a few bank accounts, maybe a retirement account — professional preparation of the US side runs roughly $600 to $1,200 per year at specialist firms, with FBAR preparation adding somewhere around $70 to $125. Straightforward situations land at the bottom of that range; rental property, investment accounts, or self-employment push toward the top.

A genuinely cross-border life — a US return and a Canadian return, coordinated so the credits actually line up — costs more, commonly $1,500 to $3,500+ per year depending on complexity. Foreign corporations, trusts, or certain investment funds can push past that, because each one drags in additional forms that are billed individually for a reason: they’re where the preparation hours actually go.

So: call it $800 a year at the simple end, a few thousand at the complex end. Real money. Annual. Forever, or at least for as long as the obligations exist. That’s the full, honest size of Column A — and it’s the number that makes people close the browser tab.

Column B: what non-compliance can cost

Here is the column almost nobody prices before deciding.

The non-willful tier. If you fail to file the foreign account report (FBAR) and the failure was an honest one — you didn’t know, nobody told you — the civil penalty runs up to $16,536 per year at 2026’s inflation-adjusted level. After the Supreme Court’s Bittner decision, that’s per annual report, not per account, which genuinely helped people with many accounts. It is still more than a decade of professional prep fees, per missed year, for a mistake you didn’t know you were making.

The willful tier. If the government concludes you knew — or, as recent court rulings have confirmed, were reckless about knowing — the penalty becomes the greater of $165,353 or 50% of the account balance, per account, per year. Run that across a few accounts and a few years and the penalties can exceed what’s in the accounts. This is not theoretical: the case law we’ve covered in our News & Cases section involves real people with eight-figure judgments. Willful violations also carry criminal exposure — fines up to $250,000 and prison time — reserved for serious cases, but on the books.

The quieter penalties. The FBAR isn’t the only form with teeth. The foreign-asset statement that attaches to the tax return itself carries a $10,000 statutory penalty per missed form, climbing to $50,000 if you ignore an IRS notice about it. Foreign corporations and certain foreign investments have their own per-form penalty regimes. These stack alongside the FBAR numbers, not instead of them.

And the part that surprises everyone: none of this depends on owing tax. Most Americans abroad owe little or no US income tax after credits and exclusions — which means the income tax penalties, calculated as percentages of unpaid tax, often round to zero. The information-return penalties don’t work that way. They’re flat amounts per form, per year. You can owe $0 in tax and six figures in penalties. That asymmetry is the entire reason this article exists.

The column between the columns

Now the part that fear-based marketing leaves out, and we won’t: the maximum penalty is not the typical outcome.

The IRS regularly reduces or waives non-willful penalties where there’s reasonable cause. More importantly, formal catch-up paths exist precisely for people whose failures were innocent:

For someone who filed returns and reported income but missed the account report, the delinquent-filing procedure frequently resolves with no penalty at all. For someone behind on returns too, the streamlined program for people living abroad covers three years of returns and six years of account reports with a 0% offshore penalty for those who qualify as non-willful. The professional cost of going through it — typically $1,800 to $3,000 in prep fees at specialist firms, more for complex situations — is the price of converting an open-ended exposure into a closed, known one.

Every one of those paths shares a single condition: you get there before the government contacts you. Once a letter arrives, the voluntary options narrow or vanish, and you’re negotiating from Column B.

Two composite pictures

These are anonymized composites of how the math typically plays out — not any individual’s case, and not a prediction of yours.

Picture one. A US citizen who has lived abroad for eight years, never filed, owes essentially nothing in tax. Goes through streamlined: three returns, six account reports, 0% penalty, roughly $2,000–$3,000 in professional fees, then ~$1,000/year ongoing. Total cost of the entire problem: a few thousand dollars and some paperwork. Sleeps fine.

Picture two. Same person, but the IRS finds them first — through the bank-reporting network that now exists in over a hundred countries, this is a when-not-if mechanism. Best realistic case: non-willful penalties negotiated down, plus professional fees for the defense, plus years of process. Worse case: facts that look reckless (an account never mentioned to a preparer, a “no” checked on a form that should have been “yes”), and the willful framework enters the conversation. The same underlying situation now costs tens of thousands at minimum — with no ceiling that anyone can promise in advance.

The difference between the two pictures is not the person’s history. It’s who moved first.

The honest summary

Compliance is a known, bounded, recurring cost: high hundreds to low thousands per year, more for complex lives. It’s annoying, and the annoyance is legitimate — paying four figures annually to report that you owe nothing is a defensible thing to resent.

Non-compliance is not a cost. It’s an unbounded tail risk with five- and six-figure outcomes attached, where the size of the outcome depends heavily on a single variable — voluntary versus discovered — that stops being yours to control the moment you’re found.

That’s the whole comparison. Column A is a subscription. Column B is a lottery ticket where you’re trying to lose. Nobody can run this math for you, but it deserves to be run with both columns filled in — and if reading this is the first time you’ve seen the second column, that’s exactly the situation the catch-up programs were built for.
