FBAR and FinCEN Form 114: does your crypto trigger a foreign-account report?

The FBAR is one of the most misread parts of a crypto return. People hear "over ten thousand dollars abroad" and assume a tax bill is coming. The FBAR is not a tax. It is a disclosure form, and for crypto the question of whether it even applies has moved over the past few years. This walks through what the form is, where foreign crypto sits under the current rules, and how to work out your own answer.

Start with the plain version. If the combined value of your accounts held outside the United States topped $10,000 at any point during the year, you generally file. For crypto the "held outside the United States" part is where most of the real questions live.

What the FBAR actually is

FBAR stands for Report of Foreign Bank and Financial Accounts. The form is FinCEN Form 114, and you file it electronically through FinCEN's BSA E-Filing System. It does not go with your Form 1040. It is a separate filing to the Treasury, and no tax is calculated on it. You are reporting that the accounts exist.

The trigger is a $10,000 aggregate. Add up the highest value each of your foreign accounts reached during the year, in US dollars. If that combined figure crossed $10,000 for even a single day, the threshold is met and every foreign account you hold gets listed, not only the one that pushed you over. The deadline is April 15, with an automatic extension to October 15 that you do not have to request.

Does crypto count? The honest 2026 answer

This is the part the old blog posts got wrong by oversimplifying. In Notice 2020-2, FinCEN said it intended to amend the FBAR regulations so that a foreign account holding virtual currency would be reportable. As of 2026 that rule has not been finalized. So a foreign account that holds only crypto is, on its own, generally not yet FBAR-reportable under the current regulations.

Two things keep that from being a free pass. First, many custodial exchange accounts also hold a fiat balance, and a foreign account holding cash or other reportable assets can already put you over the line. Second, FinCEN has signaled the change is coming, and the day the rule is finalized, foreign crypto accounts move squarely into scope. Because the downside of guessing wrong is large and the cost of filing is a form, some people file protectively even under today's rules. Informational, not tax advice.

Which situations actually reach the form

The self-custody point trips people up, so it is worth stating flatly. FBAR is about accounts at institutions. If you control the private keys yourself and no company holds the crypto for you, there is generally no foreign account to report. Whether an offshore exchange is "foreign" comes down to where it is organized and located, not where you happen to log in from.

How the $10,000 test works

The threshold is measured on the highest value during the year, not the year-end balance. If your foreign account spiked to $14,000 in the spring and drifted back to $3,000 by December, you still crossed the line. Convert each account's peak to US dollars using the Treasury year-end rate the instructions point to, add the accounts together, and compare the total to $10,000. If the total is over, the whole set gets reported.

Form 8938 is a separate form, not the same thing

People mix up the FBAR with Form 8938, and they are different filings with different rules. Form 8938, the Statement of Specified Foreign Financial Assets, comes from the FATCA law, files with your tax return, and starts at higher thresholds that vary by filing status and whether you live abroad. The IRS has signaled that foreign-held crypto may fall under 8938 as guidance develops, so someone with meaningful offshore holdings can end up filing both. They do not substitute for each other.

The penalties, and what Bittner changed

The reason the FBAR gets attention is the penalty structure. A non-willful failure to file carries a penalty set at $10,000 per report by statute, adjusted upward for inflation each year, which has pushed it above $16,000 in recent years. A willful failure is far worse: the greater of a six-figure statutory amount, also inflation-adjusted, or 50 percent of the account balance, with criminal exposure possible in the worst cases.

One recent case matters here. In Bittner v. United States (2023), the Supreme Court held that the non-willful penalty applies per annual report, not per account. Before that ruling, the IRS had stacked the penalty account by account, which turned a handful of unreported accounts into an enormous number. The per-report reading is meaningfully more forgiving, though it does not make missing the form free.

If you missed past years

Late FBARs are fixable, and the path depends on your facts. If you have no unreported income tied to the accounts and the IRS has not contacted you, the delinquent FBAR submission procedures let you e-file the missing reports with a short reason for filing late. If there was unreported income and the failure was non-willful, the streamlined filing compliance procedures are the usual route. Correcting it before the IRS raises it is almost always cheaper and calmer than waiting.

What to check this year

1. List anything held outside the US. Offshore exchanges, foreign brokerage or bank accounts, anything an institution holds for you abroad.
2. Find the highest combined balance. Peak value during the year, converted to US dollars, added across accounts.
3. Check whether any foreign account held fiat. A cash balance on an offshore exchange can put you over the line under today's rules.
4. Watch for the FinCEN rule. When the virtual-currency amendment is finalized, crypto-only foreign accounts become reportable.
5. File by the deadline, or file protectively. April 15, with the automatic extension to October 15, and consider filing even when the answer is uncertain.

The form itself is short and costs nothing to file. The expensive outcomes come from ignoring a foreign account, not from disclosing one.
