If your foreign exchange account also holds any regular currency or other financial assets, the whole account can trigger an FBAR filing once your foreign accounts total more than $10,000. The rules are also actively changing.

This article explains what is required now, where the traps are, and how to fix missed filings. To review your exposure with counsel, call (415) 968-1780.

What the crypto FBAR rules require right now

The FBAR, filed on FinCEN Form 114, requires U.S. persons to report foreign financial accounts when the combined value tops $10,000 at any point in the year. Under FinCEN Notice 2020-2, issued at the end of 2020, an account that holds only virtual currency is not currently defined as a reportable account.

As of the 2026 filing season, FinCEN has not finalized a rule changing that, though it has signaled its intent to do so. So on paper, a pure crypto holding at a foreign exchange sits outside the FBAR for now. The problem is that very few accounts are actually pure crypto.

The hybrid-account trap

Most foreign exchange accounts hold more than coins. The moment your account also holds fiat currency, a stablecoin treated as cash, or other financial assets, it looks like an ordinary reportable account, and the whole thing counts toward your FBAR once you cross the $10,000 aggregate threshold.

Because so many exchange accounts carry a cash or stablecoin balance, the “crypto is not reportable” headline misleads a lot of people into skipping a filing they actually owe. This is the single most common way crypto holders miss an FBAR without realizing it.

Self-custody wallets versus exchange accounts

Where you hold the crypto matters. Coins you control directly in a self-custody wallet, where you hold the private keys, generally are not an “account” with a foreign financial institution, so they usually fall outside the FBAR. An account at a foreign exchange or custodian is the opposite case: it is exactly the kind of relationship the FBAR was built to capture.

The analysis turns on facts about custody and the platform, which is why a close look at each account is worthwhile rather than a blanket assumption either way.

What about FATCA and Form 8938?

Form 8938, the FATCA statement of specified foreign financial assets, is a separate filing with higher thresholds, starting at $50,000 for many taxpayers. The IRS has not issued definitive guidance on whether foreign-held cryptocurrency must be reported on Form 8938, so it is unsettled.

Given the uncertainty and the penalties for getting it wrong, many advisors take a conservative approach and report, especially where the crypto is held through a foreign account or entity.

Why many advisors report conservatively

When a rule is unsettled and about to tighten, the math often favors filing. The burden of reporting a foreign account is modest. The cost of a missed FBAR is not. With FinCEN signaling a change, exchange data flowing to the government, and penalties as steep as they are, filing on a protective basis is frequently the prudent call. That is a judgment to make with counsel based on your specific accounts, not a blanket rule.

The penalties are severe

FBAR penalties are why this matters. For non-willful violations, the penalty runs to roughly $16,500 per report for 2026, and the Supreme Court’s decision in Bittner v. United States confirmed that the non-willful penalty applies per report rather than per account.

For willful violations, the penalty is far higher, generally the greater of about $165,000 or 50% of the account balance, and in extreme cases willful failures can carry criminal exposure. These figures adjust for inflation, so confirm the current numbers, but the order of magnitude is the point: this is not a nuisance filing.

How to fix missed crypto FBARs

If you should have filed and did not, you have paths back into compliance, and the right one depends on whether the failure was willful. Non-willful taxpayers may file late FBARs with a reasonable cause statement or use the streamlined procedures; willful conduct points toward the formal voluntary disclosure route.

Frequently asked questions

Do I have to report crypto on the FBAR?

As the rules stand for the 2026 filing season, an account holding only virtual currency is not currently FBAR-reportable under FinCEN Notice 2020-2, and no final rule has changed that yet. But if the account also holds fiat, a stablecoin treated as cash, or other assets, the whole account is reportable once your foreign accounts exceed $10,000. FinCEN has signaled it intends to expand FBAR reporting to virtual currency, so this can change.

What if my foreign exchange account also holds dollars or stablecoins?

Then it is very likely reportable. A mixed or “hybrid” account that holds fiat or cash-like assets alongside crypto counts as a reportable foreign account, and the entire account value goes toward the $10,000 threshold. This is the most common way crypto holders unknowingly miss an FBAR.

Is a self-custody wallet reportable on the FBAR?

Generally no. Crypto you hold directly in a self-custody wallet, controlling your own private keys, usually is not an account with a foreign financial institution and typically falls outside the FBAR. Custody and platform facts drive the analysis, so confirm your specific situation.

What are the penalties for a missed crypto FBAR?

For 2026, non-willful violations run to roughly $16,500 per report (per report, not per account, after Bittner v. United States), and willful violations to about the greater of $165,000 or 50% of the account balance, with criminal exposure possible in extreme cases. The figures are inflation-adjusted, so confirm current amounts.

How do I fix FBARs I should have filed?

Options include filing late FBARs with a reasonable cause statement and the streamlined procedures for non-willful taxpayers, and the formal voluntary disclosure route where willfulness is a concern. The IRS ended its former no-penalty Delinquent FBAR Submission Procedures in July 2026. The right path depends on your facts and should be chosen with an attorney before you file anything.
