If the combined balance of your foreign financial accounts exceeds a threshold at any point during the year, you have a reporting obligation that exists independently of whether you owe any tax. It is filed separately, with a different agency, on a different system, and missing it carries penalties out of proportion to the amounts involved.
Many people who owe it do not know it exists.
This is general information, not legal or tax advice. Penalties are severe; consult a qualified professional if you may have an obligation.
What changed in 2026
- Information exchange continued expanding. Automatic reporting between financial institutions and tax authorities made unreported accounts more visible.
- Enforcement stayed active. Penalty assessments continued for both non-willful and willful failures.
- Correction procedures remained available. Programmes for coming into compliance for past years continued to exist for those who qualify.
- Digital asset treatment stayed ambiguous. Whether certain digital asset holdings at foreign platforms are reportable remained an area of uncertainty, with guidance evolving.
Who has to file
| Situation |
Reportable |
| Foreign bank accounts you own |
Yes |
| Foreign brokerage accounts |
Yes |
| Foreign pension or retirement accounts |
Frequently yes |
| Accounts where you have signature authority only |
Yes, generally |
| Foreign insurance with cash value |
Frequently yes |
| Jointly held accounts with a spouse |
Yes, full value |
| Foreign real estate held directly |
No; property itself is not an account |
| Foreign account below the threshold, alone |
Yes if the aggregate exceeds it |
The aggregate rule catches people. If you hold several modest foreign accounts, none individually above the threshold, but the sum exceeds it at any point in the year, all of them are reportable. Someone with a small legacy account in their country of origin plus a modest current account can cross the line without noticing.
The signature authority rule catches a different group. An employee who can sign on their employer's foreign account may have a reporting obligation on an account they do not own and hold no money in.
The measurement is the maximum value during the year, not the year-end balance. A temporary spike above the threshold triggers the obligation for the whole year.
Penalties and correction
Penalties for non-willful failure are meaningful. Penalties for willful failure are severe, potentially a substantial percentage of the account balance per year, and criminal exposure exists in serious cases.
The distinction between non-willful and willful turns on facts including whether you knew of the obligation and whether you took steps to conceal. Someone who genuinely did not know is in a different position from someone who did.
Correction procedures exist for people who failed to file and are not under examination. Where the failure was non-willful and there is no unreported income, a streamlined path may be available. These programmes have eligibility conditions and using the wrong one is itself a problem, which is why this specific situation warrants professional advice rather than self-help.
Note that this obligation is separate from, and additional to, foreign asset reporting on your tax return itself, which has different thresholds and covers a different set of assets. Both can apply to the same accounts, and filing one does not satisfy the other.
Common mistakes
- Not knowing the obligation exists. The most common failure.
- Applying the threshold per account. It is aggregate.
- Using the year-end balance. The maximum during the year governs.
- Ignoring signature-authority accounts. Reportable even without ownership.
- Assuming the tax return form covers it. They are separate obligations.
- Attempting self-correction for past years. Choosing the wrong procedure creates problems.
FAQ
What is the threshold?
An aggregate amount across all foreign accounts, measured at the maximum during the year. Confirm the current figure, which has been stable but should be verified.
Do I file if I owe no tax?
Yes. The obligation is independent of tax liability.
What about foreign retirement accounts?
Frequently reportable, with treatment depending on the account type and jurisdiction. Do not assume exemption.
How far back can penalties reach?
There is a statute of limitations, longer than for many tax matters. Correction programmes address prior years for those who qualify.
