Traditional banks vs fintech for your LLC: where to open your account

0 dollars a month and onboards online in 5 days. Mercury ($0 wires, FDIC $5M), Relay (20 free sub-accounts), Wise (50+ currencies) vs Chase and Bank of America (in-person required). Honest comparison for non-resident LLC owners.

Mercury charges 0 dollars a month and onboards online in 5 days; a traditional bank like Bank of America requires physical presence in the US and 25 to 50 dollars in monthly maintenance.

When opening a bank account for your US LLC, you have two main options: traditional banks and fintech companies. Here's an honest, detailed comparison.

Traditional banks for US LLCs

Major US banks like Chase, Bank of America, Wells Fargo, and Citibank offer business accounts. But for non-resident LLC owners, they're often impractical:

The problem:

Most require in-person account opening at a US branch
Many require a US SSN or ITIN from the applicant
They're not designed for international online businesses
Monthly fees: $15-30/month minimum
Wire transfer fees: $15-45 per wire (sending), $15-25 per wire (receiving)
Minimum balance requirements: often $1,500-5,000

The exception: Some traditional banks with strong international departments (like some Citi branches) may accommodate non-residents, but the process is complex and not guaranteed.

Bottom line: Traditional US banks are generally not the right choice for non-resident LLC owners today.

Fintech options: the practical choice

Best feature: Real mid-market exchange rates, minimal conversion fees (0.4-1.5%)
Limitations: Not a bank, higher compliance scrutiny, funds not FDIC insured (safeguarded but not FDIC protected)

Best for: Receiving international payments in multiple currencies, currency conversion. Never as primary business account.

Slash: corporate treasury

Type: Treasury management platform, not a bank
What it offers: Yield on idle cash for your LLC
Best feature: Your operating reserves generate returns while sitting in the LLC
Ideal for: LLCs with consistent revenue who don't distribute everything immediately

Wallester: corporate cards

What it offers: Virtual and physical corporate cards with granular spend control
Best feature: Create a separate virtual card for each subscription or expense category

Ideal for: European operations, multi-currency receiving

Our recommended setup

This combination gives you FDIC protection, free wires, multi-currency capability, yield on idle cash, granular card control, and redundancy.

The importance of redundancy

Never depend on a single account. If Mercury has a temporary compliance review, you need Relay as backup. If Wise restricts your account during a review, you need another currency conversion path. Redundancy is not paranoia. it's professional risk management.

Traditional bank vs. fintech: the complete decision matrix

The optimal setup: hybrid approach

Most Exentax clients use this configuration:

Mercury (primary). All revenue deposits, all operating expenses, main treasury
Relay (secondary/backup). Sub-accounts per client, secondary checking, emergency backup
Wise Business: Currency conversion at real rates (EUR, GBP, MXN, COP)
Wallester: Virtual cards for each subscription (automated expense tracking)
Slash: Corporate treasury (yield on idle cash, NOT a bank)

Total monthly cost for this entire infrastructure: $0. (Wise charges only on conversions, Wallester has per-card fees, everything else is free.)

Banking and tax facts worth clarifying

Fintech and CRS information evolves; here is the current state:

How to read the bank-vs-fintech choice as a profile question rather than a brand contest

The bank-vs-fintech choice for an LLC reads more usefully when it's treated as a profile question rather than as a contest between two categories. The decision depends on three operational variables — number of monthly operations, complexity of the operating chain, and need for in-person interaction — and the same operating profile can land on different sides of the choice depending on how those variables weigh in the concrete case.

How to capture the choice in a short written note

The choice captures more durably in a short, dated note that lists the three variables and the conclusion they yield, so the discussion doesn't have to be repeated whenever a new account is considered.

How to read the bank vs fintech choice as a stable mapping rather than as a brand discussion

The bank vs fintech choice reads more usefully as a stable mapping between the type of vehicle, the country of residence of the beneficial owner and the type of incoming flows expected, than as a brand discussion.

Notes by provider

Mercury operates with several federally chartered partner banks and FDIC coverage via sweep network: mainly Choice Financial Group and Evolve Bank & Trust, with Column N.A. still in some legacy accounts. Mercury is not itself a bank; it is a fintech platform backed by those partner banks. If Mercury closes an account, the balance is typically returned by paper check mailed to the account holder's registered address, which can be a serious operational problem for non-residents; keep a secondary account (Relay, Wise Business, etc.) as contingency.
Wise ships two clearly different products: Wise Personal and Wise Business. For an LLC you must open Wise Business, not the personal account. Important CRS nuance: a Wise Business held by a US LLC sits outside CRS because the account holder is a US entity and the US is not a CRS participant; the USD side operates via Wise US Inc. (FATCA perimeter, not CRS). In contrast, a Wise Personal opened by an individual tax-resident in Spain or another CRS jurisdiction does trigger CRS reporting via Wise Europe SA (Belgium) on that individual. Opening Wise for your LLC does not bring you into CRS through the LLC; a separate Wise Personal in your own name as a CRS-resident individual does report.
Wallester (Estonia) is a European financial entity with an EMI/issuing-bank licence. Its European IBAN accounts are within the Common Reporting Standard (CRS) and therefore trigger automatic reporting to the tax administration of the holder's country of residence.
Payoneer operates through European entities (Payoneer Europe Ltd, Ireland) that are also in scope for CRS for clients resident in participating jurisdictions.
Revolut Business: when paired with a US LLC, it operates under Revolut Technologies Inc. with Lead Bank as its US banking partner. The account delivered is a US account (routing + account number); no European IBAN is issued to a US LLC. The European IBANs (Lithuanian, Belgian) belong to Revolut Bank UAB and are issued to European clients of the group. If you are offered a European IBAN tied to your LLC, confirm exactly which legal entity holds that account and which regime it reports under.
Zero tax: no LLC structure delivers "zero tax" if you live in a country with CFC/tax transparency or income attribution rules. What you achieve is no double taxation and correct reporting at residence, not elimination.

What follows is the operational view, not the textbook one. We have run this play enough times to know which variables collapse first under scrutiny from a tax authority or a banking compliance team, and that is the order we tackle them in.

Let's talk about your structure

We treat this block as one of the load-bearing decisions of the LLC strategy: get it wrong and the rest of the structure leaks tax, banking access or compliance. The notes below distil what we actually do with clients facing this exact case, prioritising the variables that move the needle.

How to decide between a traditional bank and a fintech for your LLC

The "bank or fintech?" question has a less romantic answer than LinkedIn suggests: it depends on your activity risk profile, the country you operate from and how much weight you give to online availability over robustness in an extended KYC. These are the axes we use in every case.

Real availability for non-residents. Mercury, Relay and Wise Business are the three options that accept non-residents with a reasonable approval ratio. Federal banks (Chase, BofA, Citibank) require an in-person US visit and, in many branches, your own US address. If you sit abroad, fintech is the practical entry point.
Robustness in extended KYC. Mercury runs through Choice Financial, Evolve Bank & Trust and Column N.A. with FDIC sweep coverage. On closure, the balance is sent by cheque to the registered address - operationally hard for non-residents. Keeping a second live account (Relay or Wise Business) is a contingency, not paranoia.
Real multi-currency. Wise Business gives European IBANs, local USD numbers, local GBP and conversions at the interbank mid-rate. Mercury is USD-centric with limited FX. For recurring EUR/GBP collections, Wise Business wins; for primary USD operations, Mercury still leads.
Gateways and compatibility. Stripe, PayPal, Paddle and DoDo integrate without friction with any of the three; Brex and Ramp no longer accept non-residents for corporate cards - beware of older posts still recommending them.

What we are asked the most

Do I lose FDIC coverage by using a fintech? No, as long as the fintech runs via FDIC sweep network partner banks (Mercury, Relay). The cap is USD 250,000 per partner bank; if your balance exceeds it, spread across partner banks or open a second fintech.

What if Mercury closes my account with no warning? It is the main reason we always open two accounts in parallel and keep documentation ready for the first KYC request. Operating continuity is not improvised.

At Exentax we prepare the application, the supporting documents and the parallel-accounts strategy so that the day something moves on one account, the other one keeps your collections running.

What is a bank?

Read this section as a checklist with teeth: each point flags a real failure mode we have seen in cross-border LLC files. Skip none of them - most reassessments and account closures we clean up later trace back to one of these items.

When a traditional bank fits better than a fintech

The decision between a traditional bank and a fintech rarely

follows a universal rule. It tends to follow the specific operating

profile of the LLC: volume, geographic distribution, frequency

of large wire transfers and need for cash deposits. Walking

through these four points calmly almost always points to the

right answer for the case at hand.

On the same topic

What if HMRC, the IRS or my local tax authority asks about my LLC?

It's the question every client raises in the first consultation, and the short answer is: your LLC isn't opaque, and a properly declared structure closes any inquiry in standard forms. Your tax authority can request the state Certificate of Formation (Wyoming, Delaware or New Mexico), the EIN issued by the IRS, the signed Operating Agreement, the Mercury or Wise statements for the year, the Form 5472 plus pro-forma 1120 you filed, and the bookkeeping that reconciles income, expenses and movements. If all of that exists and is delivered in order, the inquiry doesn't escalate.

What tax authorities do pursue, and rightly, is sham ownership (nominees, paper residency) and undeclared foreign accounts. A well-structured LLC is the opposite: you appear as beneficial owner in the BOI Report when applicable (verifiable at fincen.gov/boi), you sign the bank accounts and you declare the income where you actually live. The structure is registered with the state Secretary of State, with the IRS and, when European banks are involved, inside the CRS perimeter of the OECD standard.

The mistake that really sinks an inquiry isn't having an LLC; it's not attributing the income correctly in your domestic return, not declaring foreign accounts when the year-end balance exceeds the local threshold (€50,000 in Spain via Modelo 720; the equivalent FBAR / Form 8938 in the US for residents; T1135 in Canada), and not documenting related-party transactions between the member and the LLC. Those three fronts are worth closing before any request arrives, not after.

## What an LLC does NOT do

- It does not exempt you from tax in your country of residence. If you live in Spain, France, Germany or Portugal, you are taxed there on worldwide income. The LLC organises your US side (zero federal tax for non-resident SMLLC pass-through, absent Effectively Connected Income); it does not switch off your domestic taxation. The income tax is computed on the attributed profit, not on the dividends actually paid.

- It is not an offshore vehicle or a BEPS scheme. It is a US entity recognised by the IRS, registered in a specific state with physical address, registered agent and annual informational filings. Classic offshore jurisdictions (BVI, Belize, Seychelles) leave no public trace; an LLC leaves a trace in five different places.

- It does not protect you if you commingle funds. The pierce the corporate veil doctrine kicks in as soon as a judge sees the LLC and the member behaving as the same wallet: mixed accounts, personal expenses paid from the LLC, no signed Operating Agreement, no bookkeeping. Three suspicious transactions are enough.

- It does not save you social security contributions at home. If you are self-employed in Spain, France or Germany, your monthly social contribution remains identical. The LLC handles the trading side with international clients; your personal contribution is independent.

- It does not exempt you from declaring foreign accounts. Spain residents file Modelo 720 / 721; UK residents, the SA106; Portugal residents, the Anexo J of Modelo 3 IRS; Germany residents, the Anlage AUS. Those obligations belong to the individual, not to the LLC.

At Exentax we cover those five fronts every year alongside the US federal calendar (Form 5472, pro-forma 1120, FBAR, state Annual Report and BOI Report when applicable). The goal is that no inquiry finds a loose end and that the structure withstands a 5-to-7-year retroactive review.
