Wise Business as US Bank Account: Can It Work?

I've used Wise Business alongside traditional US bank accounts since 2019, across entities in the US, Hong Kong, and Australia. It does exactly what it says it does. The problem is that founders keep assuming it does things it never claimed to do.

Wise serves over 16 million customers and processes more than $12 billion in cross-border transactions per quarter (Wise plc). It gives you a US routing number, an account number, and the ability to receive ACH transfers. To your clients, it looks like a US bank account. But Wise is not a US bank. That distinction surfaces at inconvenient times: a Fedwire that bounces, a lender that won't accept your statements, a government portal that rejects your routing number.

For an LLC doing under $10,000/month with no need for lending or wire receives, Wise works fine as a daily operating account. For anything beyond that, you still need a real US bank like Mercury or Relay.

What Wise Business gives you

Here's the full picture of what you're working with:

If you invoice US clients, the flow is straightforward: client pays ACH, money lands in your USD balance, and you hold it, convert it, or move it out. The conversion rate is the actual mid-market rate, which is more than most banks can say.

What Wise Business does not give you

The gaps are specific and predictable:

The FDIC gap gets the most attention, but honestly, for a single-member LLC with under $250,000 in the account, the practical difference is small. Wise safeguards funds at regulated partner banks. If Wise became insolvent, those safeguarded funds get returned to account holders. That's different from FDIC insurance (which covers bank insolvency up to $250,000 per depositor), but neither scenario is likely. The account freeze diagnostic maps how these gaps compound when you rely on a single account.

The more immediate problem is Fedwire. Some US companies and government agencies send payments via wire, not ACH. Wise is built for ACH. Wire transfers to Wise account details can fail or bounce back. If even one of your clients pays by wire, you need a real US bank account.

When Wise works as a primary account

Wise works as your main US-facing account if all of the following apply:

• Revenue under ~$10,000/month
• Clients pay via ACH or international transfer
• No check deposits needed
• No Fedwire receives
• You operate in multiple currencies
• No plans for US business loans or credit

That describes a lot of non-resident single-member LLCs. A founder in Berlin invoicing three US clients, converting some USD to EUR for rent, and paying a designer in GBP can run everything through Wise.

Where Wise really earns its keep is currency conversion. It charges from 0.57% at the mid-market rate. Traditional banks mark up exchange rates 1.5-3% on top of wire fees. I've run the numbers on my own transfers: converting $5,000/month from USD to another currency saves roughly $400-1,200/year compared to bank wires. The multi-currency comparison breaks down these economics across Wise, Payoneer, and Mercury.

When you need a traditional US bank account

Wise alone falls short in a few specific situations:

• Fedwire receives. Some clients, government agencies, and platforms pay by wire, not ACH. Those payments may never reach your Wise account.
• Lending. Credit lines, business credit cards, SBA loans: all require a US banking relationship. Wise offers none of this.
• Counterparty validation. Some payment processors and government agencies check your routing number against a list of US banks. Wise's partner bank routing number passes most of the time, but not always.
• Large balances. Mercury extends FDIC coverage to $5M through sweep networks. Wise has zero FDIC coverage at any balance. If you're holding operating reserves above $50,000, that's worth thinking about. The account freeze diagnostic maps what happens when frozen funds sit in an account you can't access through another institution.
• Stripe Atlas. Atlas opens a Mercury account as part of formation. If banking access is why you're choosing Atlas, Mercury is the product that matters.

Which Wise Business agreement your account sits under

"Wise Business" is one brand and several contracts. The one binding your LLC's account depends on the country Wise assigns the account to, and that assignment is Wise's call rather than yours. The Singapore agreement states it outright: "We will determine your country of domicile on the basis of such evidence as we may determine." The US agreement carries no equivalent sentence; its section 12.1(h) lists "country domicile" only as one basis for placing limits on an account.

The distinction has teeth, because these agreements do not say the same thing about the most basic question of all — whether you can leave money sitting there. On 2026-08-27 I read the Business Customer Agreement across eight Wise regions:

The Hong Kong text, section 12.1(b), verbatim:

Your Wise Account is not a bank account or a stored value facility. Upon receiving funds in your Wise Account, you are required to promptly withdraw them or use them for onward purposes, such as sending funds or converting currency. If you fail to withdraw or use the funds within 90 calendar days, or if you use the Wise Account as a bank account or stored value facility, we may mandate the withdrawal of all funds. Failure to comply may lead to the suspension or deactivation of your Wise Account at our sole discretion.

Wise emailed Hong Kong business customers on 2026-08-24 to say it had added that sentence to 12.1(b). I received it because one of my own entities banks there. A separate Wise notice to the same entity two weeks earlier had already cited a 90-day activity requirement, so the direction of travel predates the amendment — what the amendment adds is the consequence: a mandated withdrawal of the full balance, and suspension or deactivation for not complying.

The US agreement runs the other way. Funds do not expire, and inactivity is handled as escheatment rather than as a usage rule: "Your Wise Account will be considered dormant if, for a continuous period of three (3) to five (5) years, depending on applicable law, you have not logged in, sent funds, received funds, or conducted other transactions that post to your Wise Account."

Two things follow, and they point in opposite directions.

The 90-day rule is not a general Wise rule. Quoted anywhere without the Hong Kong scope attached, it is simply wrong. A non-resident-owned US LLC sitting under the US agreement has no 90-day clock, and the FDIC gap described above remains the real constraint on parking reserves in a Wise balance.

Permission to hold is a contract term, not a product feature. It differs by region right now, and it changed in one region this month. Whatever the marketing page says about holding 50+ currencies, the document that governs your balance is whichever of these agreements Wise decided applies to your account.

What I could not establish: which agreement Wise assigns to a US LLC whose owner lives elsewhere. The terms describe that determination as Wise's own, made on evidence Wise selects, and I found no published page mapping owner residence to a governing agreement. Canada and Malaysia return 404 at the same URL pattern the other eight regions use, so those two are unchecked rather than confirmed absent.

The two-account structure

This is what I actually run, and what I see most non-resident founders settle on: a US bank account (Mercury or Relay) for domestic banking, and Wise for everything international.

Mercury (or Relay) is the bank of record for the LLC. It receives US client payments and produces the statements your accountant and the IRS expect to see. Wise handles the cross-border plumbing: converting USD, paying overseas contractors, receiving payments in other currencies.

Yes, two accounts adds friction. But it eliminates the gaps of either one alone. The banking comparison tool models these combinations.

Wise Business account opening for LLCs

You'll need four things:

• EIN (Employer Identification Number)
• Articles of organization (from the state of formation)
• Proof of business activity or business description
• Owner identification (passport, proof of address)

Approval commonly takes 1-3 business days. Wise has noticeably higher acceptance rates than Mercury or Relay for non-resident applicants, especially newly formed LLCs with no revenue history. If you've just formed a US LLC as a non-resident and need an account open this week, Wise is the path of least resistance. You can always add Mercury later once your revenue justifies the additional banking relationship.

FBAR implications

This catches people off guard. Wise holds funds at financial institutions outside the United States, which means US persons (citizens, green card holders, substantial presence qualifiers) trigger FBAR filing obligations. If the aggregate max value of all your foreign accounts exceeds $10,000 at any point during the year, FinCEN Form 114 is due by April 15 (auto-extended to October 15). Willful failure to file can cost you the greater of $100,000 or 50% of the account balance (31 USC 5321).

Non-US persons don't face FBAR personally. But the LLC itself may have its own LLC-level FBAR obligation if it holds foreign accounts. And Wise transactions between you and the LLC are reportable on Form 5472.

Key Takeaways

• Wise Business gives you US account details (ACH routing + account number) but is not a bank. No FDIC insurance. Fedwire may not route correctly.
• For LLCs under $10,000/month with no lending or wire needs, Wise works as a daily operating account at $0/month.
• Currency conversion from 0.57% at the mid-market rate saves $400-1,200/year compared to bank wire markups of 1.5-3%.
• Most non-resident founders end up running two accounts: Mercury or Relay for US banking, Wise for multi-currency operations.
• "Wise Business" is several regional contracts. The US agreement says funds do not expire; the Hong Kong agreement added a 90-calendar-day withdraw-or-use rule on 2026-08-24. Which one governs your account is Wise's determination.

Frequently Asked Questions

Is Wise Business FDIC-insured?

No. Wise is an electronic money institution, not a bank. Your funds are safeguarded at regulated partner banks, meaning they sit in segregated accounts and would be returned if Wise went insolvent. That's a different mechanism than FDIC insurance, which covers depositor losses when a bank fails. For balances under $50,000, the practical difference is small, but the structural distinction exists.

Can I receive US client payments through Wise Business?

Yes, as long as they pay via ACH. The client sends an ACH transfer to your Wise routing and account number, and funds land in your USD balance. Fedwire is a different story: wire transfers may fail or bounce back. Always ask a new client whether they pay by ACH or wire before sharing your Wise details.

Does Wise count as a foreign account for FBAR?

For US persons (citizens, green card holders), yes. Wise holds funds outside the US, so the account is reportable on FinCEN Form 114 if your total foreign account balances exceed $10,000 at any point during the year. Non-US persons don't face FBAR, but Wise transactions between you and the LLC are still reportable on Form 5472.

Does Wise force you to move money out every 90 days?

Only under the Hong Kong Business Customer Agreement. Wise notified Hong Kong business customers on 2026-08-24 that it had added a 90-calendar-day withdraw-or-use sentence to section 12.1(b), and the clause is live on the agreement page. The US agreement says the opposite — "The funds held in your Wise Account do not expire" — and treats inactivity as escheatment after three to five years, not as a usage rule. I checked eight regional agreements on 2026-08-27 and Hong Kong was the only one carrying the 90-day clause. Which agreement covers a given account is Wise's determination, so the answer for your account follows from the region Wise assigned it to, not from the Wise brand.

Can I use Wise Business to pay my LLC's state fees?

Usually, yes. Delaware's Division of Corporations and Wyoming's Secretary of State both accept online payments, and the ACH transfer from Wise's US routing number passes their validation. I've personally paid Wyoming fees from Wise without issues.
