The short version
A hardware wallet's location is not a complete foreign-reporting analysis. Identify who holds the assets, whether there is an account with a foreign institution, and whether the asset represents an interest in a foreign entity or another reportable financial asset. Then consider the Report of Foreign Bank and Financial Accounts (FBAR), Form 8938 and any transaction reporting separately.
Do not assume that self-custody makes all reporting disappear. Equally, do not assume that carrying a device abroad creates a foreign bank account. The legal relationship and assets matter, not just the device or a website's domain.
FBAR: start with the account
FinCEN Notice 2020-2 states that the FBAR regulations do not define a foreign account holding virtual currency as reportable, unless it is reportable because it holds other reportable assets. The notice also states an intention to propose a regulatory change. An announced intention is not itself an effective reporting rule. Check current FinCEN guidance for the year being filed.
The general FinCEN FBAR guidance applies to a U.S. person with a financial interest in or signature authority over foreign financial accounts when their aggregate value exceeds $10,000 at any time during the calendar year. That is an aggregate threshold, not a separate allowance for each account. A foreign account holding fiat currency as well as cryptocurrency needs a separate review; the virtual-currency notice is not a blanket exemption for the entire relationship.
Form 8938: a separate definition and threshold
The Form 8938 instructions cover specified foreign financial assets, including accounts maintained by foreign financial institutions and certain foreign investments held outside accounts. Filing status, residence and asset type affect the analysis. An FBAR conclusion cannot simply be copied into Form 8938.
For cryptocurrency arrangements, identify the contracting entity, account terms, custodial relationship and any underlying issuer or counterparty. The cited instructions do not provide a universal crypto-only exemption. This article does not classify every token or self-custody arrangement as either reportable or exempt.
| Reporting item | Numeric reference and its limit | Source |
|---|---|---|
| FBAR | More than $10,000 aggregate foreign financial-account value at any time, subject to reportability rules | FinCEN FBAR guidance |
| Form 8938, unmarried individual living in the U.S. | More than $50,000 at year-end or $75,000 at any time; different thresholds apply to other categories | Types of Reporting Thresholds |
| Form 8300 | The familiar more-than-$10,000 cash rule concerns business receipts, not merely holding a wallet | Announcement 2024-4 |
Form 8300 is not a wallet-registration form
Announcement 2024-4 provides transitional treatment for digital assets under section 6050I: digital assets need not be included in determining reportable cash receipts until implementing regulations are issued. The announcement does not suspend the existing cash-reporting rules. Nor does it create a general exemption from income-tax reporting.
Check current guidance before applying that transition to a particular receipt. A business cash receipt, a foreign financial account and a sale generating taxable gain answer different reporting questions. None is a reason to register private keys with an unsolicited portal.
Make a custody map before deciding what to file
As a practical record exercise, list each exchange or custodian, its legal entity and country, account numbers, assets held during the year and maximum values. Separately list self-custodied wallets and any interests in foreign entities. Keep transaction history showing transfers between your own accounts so transfers are not mistaken for unexplained acquisitions.
For prior years, determine residency and the filing obligation year by year before choosing a correction route. Do not label conduct nonwillful or select a disclosure program from a general article. An international-information-return review is outside a routine individual domestic-resolution evaluation and requires its own scope.

Discuss your situation
For a scoped engagement inquiry, email Noah Green with a short description of the issue and any upcoming deadline. Do not send tax returns, identifying numbers, wallet keys or other sensitive records through ordinary email. Secure document instructions follow separately. Payment and your signature may initiate an engagement request; they do not mean the case has been accepted. I review the facts after payment and must countersign the engagement letter and accept the case before work begins. The accepted written engagement governs scope. Contacting me does not extend an IRS deadline.
