Modern expats hold money in places the FBAR regulations never imagined: multi-currency apps, borderless accounts, payment wallets. The reporting question sounds simple — does a Wise, Revolut, PayPal or similar fintech balance count as a "foreign financial account" for the FBAR? — and the honest answer is: mostly yes, with one famous gray zone. Here is how the definition applies and the conservative playbook.
The definition that decides it
The FBAR applies to accounts at a "financial institution," and the regulation (31 CFR 1010.350) defines financial institution broadly: banks, brokers, and — critically for fintech — entities "in the business of accepting deposits as a financial institution," including issuers of payment cards and e-money institutions where the balance functions like stored money you can draw on. The IRS's FBAR reference guide also pulls in "accounts where the holdings are commingled and the owner's interest is in the fund balance."
Two carve-outs matter for the fintech question: arrangements that are purely payment channels (funds move through, nothing rests), and prepaid card programs limited to spending the loaded value. Money parked, invested, or accumulating interest does not fit the carve-outs.
Provider by provider
| Provider | Generally FBAR-reportable? | Why |
|---|---|---|
| Wise (TransferWise) | Yes, in most practitioner analyses | Holds balances as an e-money institution; the balance functions as an account |
| Revolut | Yes, generally | Licensed foreign financial institution; customer balances held as accounts |
| OFX, WorldRemit-held balances | Yes, where balances rest | Same stored-balance logic |
| Interactive Brokers (UK/Ireland entity) | Yes | It's a brokerage — never in doubt |
| Crypto exchanges abroad | Fact-dependent | Depends on whether the platform creates a customer account holding funds; see FinCEN's virtual-currency guidance |
| PayPal | Gray zone | Payment-processor character vs. stored balances; practitioners split; conservative filers report |
The PayPal disagreement is real and worth understanding: a long line of practitioner commentary treats an ordinary PayPal balance as outside the FBAR because PayPal is fundamentally a payment intermediary, while the conservative school points out that idle balances sitting in the wallet look exactly like the stored-value accounts the regulation captures. With penalties riding on the answer, many filers with large aggregates simply report it and remove the argument.
The entity-location nuance that decides Wise accounts
"Where is the provider?" is the wrong question; "which licensed entity holds MY balance?" is the right one. The same app can be a foreign account for one user and a domestic non-event for another:
- Wise holds balances through different licensed entities depending on how you opened the account. Accounts opened with a US address are generally held by Wise's US-licensed entity — a domestic arrangement that does not belong on an FBAR. Accounts opened with a non-US address are typically held by the Belgian or UK e-money institutions — reportable. Your account documents (or the entity named in Wise's terms for your region) settle it in two minutes.
- Revolut serves most customers through its Lithuanian bank license; US customers of Revolut's American operations are a different stack entirely. Same rule: check which entity your agreement is with.
- A "US company" brand means nothing — the app in your hand is a brand; the FBAR test runs on the legal entity holding the money.
A worked example: the four-account expat
A software developer in Berlin has, at various 2026 peaks: a German bank account at €9,500 (~$10,300), a Wise balance spanning EUR/GBP at $2,100 combined, a Revolut wallet at $650, and $4,800 in Interactive Brokers (Ireland). PayPal occasionally holds $150 from marketplace sales.
| Account | Peak value | FBAR entry? |
|---|---|---|
| German bank | $10,300 | Yes — foreign bank |
| Wise (opened with German address) | $2,100 | Yes — one entry, all currencies combined |
| Revolut | $650 | Yes — once the threshold is crossed, everything reportable gets listed |
| Interactive Brokers (IE) | $4,800 | Yes — foreign brokerage |
| PayPal | $150 | Gray zone; conservative filers list it in this position anyway |
| Aggregate | ~$17,850 + | Well over $10,000 → FBAR due, five entries |
Notice what the example teaches: the PayPal question is worth almost nothing here, and the Wise entity question is worth everything — if this filer had opened Wise with a US address before moving, the $2,100 might be a US-held balance that never touches the FBAR at all. Get the entity right, aggregate honestly, list everything that qualifies.
The aggregation trap fintech makes worse
Fintech accounts count toward the $10,000 aggregate threshold alongside your foreign bank accounts. The modern expat pattern — a German bank, a Wise multi-currency balance, a Revolut wallet, a home-country brokerage — crosses $10,000 in combination far more easily than any single provider. And once the threshold is crossed, every reportable account gets an entry, including the $400 Revolut wallet.
One more wrinkle: multi-currency balances inside one provider (Wise's EUR + GBP + USD balances, for example) are generally treated as one account for reporting — one entry, maximum total value converted to dollars.
How to report a fintech account, practically
In Part II of FinCEN Form 114: the provider's legal name and registered address (for Wise: the Belgian or UK entity on your account documents; for Revolut: the Lithuanian entity), the account identifier, "other" as the type, and the maximum US-dollar value at the year's peak. Fintech providers generally supply year-end statements or balance confirmations on request — pull them in January and drop them in your record-keeping file.
The conservative playbook
- Stored balances: report. Wise, Revolut, and similar e-money balances behave like accounts; reporting them is the majority practitioner view and the safe side of a six-figure-penalty question.
- Pure pass-through transfers: don't. Money in transit that never rests (a wire corridor with zero balance at the measurement moments) isn't an account.
- PayPal: decide with your risk tolerance. Small, transient balances lean toward the payment-channel reading; large or long-held balances lean toward reporting. This is a classic "ask a cross-border professional with your facts" question.
- Crypto on foreign exchanges: conservative inclusion until the platform-by-platform picture is clearer, especially where the exchange commingles customer funds.
- Document your reasoning. If you don't report a gray-zone account, keep a dated memo of why — the same logic as a reasonable cause statement: a considered position beats an unconsidered omission.

Frequently asked questions
Do I need to report my Wise account on an FBAR?
Generally yes, when your aggregate foreign accounts exceed $10,000. Wise (formerly TransferWise) operates as a foreign financial institution, and multi-currency balances held there behave like an account at a financial institution for FBAR purposes. Most cross-border practitioners treat Wise as reportable.
Is Revolut FBAR-reportable?
Generally yes. Revolut holds customer funds through licensed foreign financial institutions, and balances there are commonly treated as reportable foreign financial accounts when the $10,000 aggregate threshold is crossed.
Do I have to report PayPal on an FBAR?
PayPal is a genuine gray area. Because it functions primarily as a payment processor rather than an account holder, many practitioners conclude ordinary PayPal balances are not FBAR-reportable — but larger or long-held balances are conservatively reported by many filers. The IRS has never provided a clean public answer specific to PayPal.
How do I value a multi-currency account for FBAR?
Report the maximum US-dollar value the account reached during the year, converting at the exchange rate in effect at the peak (or Treasury's yearly rate as a default). Each currency balance within services like Wise is part of the same overall account for reporting purposes.
Where do fintech accounts go on the FBAR form?
In Part II, one entry per account: the provider's name and registered address, the account number or identifier, 'other' as the type where checking/savings don't fit, and the maximum US-dollar value. Joint or business-role accounts follow the standard joint-owner and signature-authority rules.
