Mercury Is Switching Partner Banks to Column N.A.: What Non-Resident LLC Owners Need to Check (2026)

Mercury, a fintech business banking platform, is moving customer accounts from one of its partner banks, Choice Financial Group, to another, Column N.A. The notice asks you to confirm your business information by a date a few weeks out; your existing accounts stay open through a transition window that runs into December 2026; and a built-in tool migrates balances and activity once you're approved. For a non-resident running a US LLC, this is a partner-bank switch, not a bank failure. The exposure is operational — a fresh information review and a funds-by-check fallback if you ignore the notice — not deposit loss.

Mercury is a fintech company, not an FDIC-insured bank. Banking services provided through Choice Financial Group and Column N.A., Members FDIC. FDIC deposit insurance covers the failure of an insured bank. Deposits in checking and savings accounts are FDIC-insured through Choice Financial Group and Column N.A. and their Sweep Program Network Banks. Certain conditions must be satisfied for pass-through FDIC insurance to apply.

I run a US LLC from outside the US, and I went through this migration notice myself on the day this article was published. The instructions below are what the flow actually asks of a foreign-owned, non-resident-operated entity — not a summary of a press release. I'm keeping the entity name and balances out of it; the pattern is what matters, and the pattern is the same for any non-resident founder banking a US LLC through a neobank.

What is actually changing

Mercury holds your accounts at a partner bank. For many existing customers that partner has been Choice Financial Group. Mercury is now moving those accounts to Column N.A., another of its partner banks. Mercury's stated reason is narrow: changes to Choice's program guidelines. It is not framed as a problem with your account.

The flow runs in a fixed sequence:

The notice also carries a stick: ignore the confirm-info step and the account is scheduled to close, with any remaining funds mailed as a physical check. That last detail is where non-residents get treated differently — more on that below.

Why Mercury is doing this

Two forces sit behind the move. One is on the record; one is industry context.

On the record: Mercury won OCC conditional approval in April 2026 to pursue its own national bank charter. A company building toward a direct charter has a reason to consolidate a sprawling partner-bank stack and standardize on banks that fit the direct, API-native model. Column N.A. is exactly that kind of bank — nationally chartered, built API-first by a co-founder of Plaid, and already powering a long list of fintechs. Mercury cites concrete upside for the moved accounts: lower currency-exchange rates on incoming wires and the ability to receive real-time payments.

The industry context — and here I'm reading the trend, not quoting Mercury's stated reason — is the cleanup that followed the 2024 Synapse collapse. Synapse was a banking-as-a-service middleware layer that sat between fintechs and their partner banks. When it failed, money got stuck because no single party held a clean, reconciled ledger of who owned what. The regulatory direction since then has favored the model where a fintech connects directly to a chartered bank with no middleware in between. Mercury moved early on this — it dropped its Evolve relationship in March 2025 — and the Choice-to-Column move continues in the same direction. Read structurally, this is a de-risking move, not a warning sign.

Why non-resident founders are the most exposed link

Strip away the specifics and a non-resident founder's banking setup has three structural weaknesses a US-resident's setup does not:

1. No branch fallback. You cannot walk into a US branch with a passport and a problem. Every interaction is remote, and every remote interaction routes through a compliance queue that runs slower and stricter for foreign-owned entities.
2. 100% neobank dependency. A US resident can keep a legacy account at a brick-and-mortar bank as a backstop. A non-resident's entire US banking surface is usually one or two fintech platforms — so a single migration, freeze, or offboarding touches everything at once.
3. The check-by-mail trap. Read the closure clause carefully. If you ignore the migration and the account closes, remaining funds are mailed as a physical check — and if your company mailing address is outside the US, the check goes to your US legal address, often your registered agent. A foreign founder waiting on a paper check routed through a registered agent is a slow, fragile way to recover your own cash. The fix is simple: complete the migration so it never comes to that.

The Synapse freeze in 2024 hit this exact population hardest, for these exact reasons. The Mercury–Column move is the opposite of that event — an orderly, tool-assisted migration with a months-long dual-account window — but it's a useful moment to check whether your structure could survive a disorderly one.

A fintech business banking platform is not a chartered bank

This is the distinction that trips founders up, and it's worth getting right because it's the whole reason a "partner bank" exists in the first place.

When you open a Mercury account, you are a customer of Mercury, a fintech business banking platform — and your deposits sit at a partner bank that holds the actual charter and the actual FDIC membership. FDIC insurance reaches your balance through pass-through coverage at that partner bank (and its sweep-network banks), provided certain conditions are met. Mercury itself is not the insured entity; the partner bank is.

That structure is why the partner bank can change without your money changing hands — you're moving from one FDIC-member partner bank to another. It's also why the same structural caveat applies to most neobanks, not just this one. Wise Business gives you US account details through a partner bank but is not itself a US bank, and that surfaces at inconvenient moments — a lender that won't accept the statements, a portal that rejects the routing number. The lesson isn't "neobanks are unsafe." It's "know which layer holds your money, because that's the layer that determines what happens when something moves."

Your migration checklist

Here's what I worked through, framed as checks rather than instructions:

• Confirm your business information early. The cohort review takes weeks. Submitting on the last day of the window leaves no room if they ask for more documentation — and for foreign-owned entities, they often do.
• Keep both account sets live until the new one is proven. The transition window exists so you're never without an account. Don't close the old Choice accounts manually; let them run in parallel until every inbound and outbound flow works on Column.
• Re-test your money rails on the new account. New partner bank can mean new account and routing numbers. Before you rely on Column, verify: your Stripe (or other processor) payout destination, your contractor payment rails, any auto-debits for taxes or software, and any client that pays you by ACH or wire.
• Update everything downstream that hardcodes the old numbers. Invoices, payment portals, accounting software, and any partner who has your account details on file.
• Treat it as a redundancy audit. If this single account moving is enough to make you nervous, that's the signal you're running without a backup. A three-layer banking architecture turns a single-provider event into a 2–3 day inconvenience instead of a full stop.
• If you're a US person, mind the FBAR line. Migrating balances doesn't change your reporting, but if you're a US citizen, green-card holder, or US tax resident, the aggregate value of your foreign financial accounts still drives your FBAR obligation. A non-US-person owner of a US LLC banking domestically is generally outside that net.

Is Mercury still the right call for a non-resident US LLC?

For a non-resident forming a Wyoming or Delaware LLC for SaaS, services, or digital products, the migration doesn't change the underlying answer — Mercury's non-resident-friendly onboarding (ITIN accepted, no SSN required), $0 monthly fees, and clean API are the same reasons it ranked first in the Mercury vs Wise vs Relay vs Rho comparison, and Column adds real-time payments and cheaper incoming-wire FX on top. It's the platform I use for my own US LLC.

If the move has you rethinking the whole stack rather than just one account, that's a different and healthier question. The answer there isn't a single provider — it's a cross-border banking stack where no single platform holds every function, so the next migration (or freeze) is a routine event instead of an emergency.
