Business banking in North America

One trade bloc, three banking systems

North America is one of the world's most integrated economic regions. The United States, Canada and Mexico trade enormously with one another under the USMCA agreement (the successor to NAFTA), and supply chains routinely cross all three borders. For banking, though, integration stops at the trade level. Each country licenses and supervises its own banks, runs its own currency and payment systems, issues its own business tax identifiers and operates its own deposit insurance. There is no single account that works across all three, so a business operating regionally opens accounts in each market.

The three systems are also strikingly different in shape. The United States has the most fragmented banking market on earth, with thousands of banks and credit unions ranging from global giants to tiny community institutions, plus a deep ecosystem of fintechs offering business accounts. Canada is the opposite: a small number of large, nationwide banks dominate, and the system is known for stability and concentration. Mexico sits between the two in development terms — bank-led, with a handful of large players, strong foreign ownership of major banks and rapid growth in digital banking and fintech.

For a founder, the practical effect is that "opening a North American account" means very different things depending on the country. The rest of this guide works through what each market requires and where the common decisions — bank versus fintech, resident versus non-resident, currency and fees — actually land.

The three countries and their currencies

Currency is the first practical difference. All three currencies float, so a business trading across borders carries real exchange-rate exposure and benefits from thinking about how it holds and converts each one.

The US dollar's role as the world's primary reserve and trade currency means many international businesses want a US account regardless of where else they operate, simply to receive and hold dollars. The Canadian dollar and Mexican peso are important regionally but less so globally, which is one reason cross-border businesses often centre their North American treasury on a US-dollar account and add local accounts where they have on-the-ground activity.

The United States: huge, fragmented and EIN-driven

The defining features of US business banking are scale, choice and the central role of the Employer Identification Number. The EIN, issued by the Internal Revenue Service, is the federal tax identifier for a business, and almost every bank requires it to open a business account, along with the entity's formation documents. Most businesses also form a legal entity first — commonly a limited liability company (LLC) or a corporation, registered at the state level — before banking.

Because the market is so fragmented, the range of providers is enormous: national banks such as JPMorgan Chase, Bank of America and Wells Fargo; thousands of regional and community banks and credit unions; and a large set of fintech providers, including Mercury, Brex, Bluevine and others, that offer business accounts with fast online onboarding (typically holding deposits through partner banks). As of 12 June 2026, many small-business and online accounts carry no or low monthly fees, though wire transfers, cash handling and exceeding transaction limits still cost money. Deposit insurance comes from the FDIC up to a per-depositor, per-bank limit; with fintechs it is worth confirming exactly how and where funds are held.

Canada: concentrated, stable and Business Number-based

Canadian business banking is shaped by concentration. A small group of large national banks — commonly referred to as the Big Five, including RBC, TD, Scotiabank, BMO and CIBC — dominate the market, supported by smaller banks, credit unions and a growing fintech sector. The system came through the global financial crisis with a strong reputation for stability, and that conservative character carries into business banking.

A Canadian business typically registers federally or provincially and obtains a Business Number from the Canada Revenue Agency, which functions as its tax identifier for payroll, GST/HST and other accounts. Banks generally require the Business Number and incorporation or registration documents to open an account. Monthly account fees and transaction-based pricing are more common than in the US small-business market, reflecting the concentrated structure. As of 12 June 2026, deposits are protected by the Canada Deposit Insurance Corporation (CDIC) up to its limit, and fintech competition is gradually broadening the options for smaller companies.

Mexico: bank-led, foreign-owned and fast-modernising

Mexico's banking sector is large, bank-led and notable for the strong presence of foreign-owned banks alongside major domestic institutions. Names such as BBVA México, Banorte, Citi's Mexican operations, Santander and others lead the market, and a vigorous fintech scene has grown quickly, helped by regulation aimed at financial inclusion in a country where a significant share of adults have historically been underbanked.

A Mexican business registers with the authorities and obtains an RFC (Registro Federal de Contribuyentes) tax registration, which is central to banking, invoicing and tax. Account opening generally requires the RFC, incorporation documents and identity verification, and traditional banks may expect more in-person interaction than US online providers. Monthly fees and minimum balances are common. As of 12 June 2026, deposits are protected by IPAB up to its threshold, and digital banking and mobile payments — including the SPEI real-time transfer system — are widely used and improving access for smaller businesses.

Banks versus digital and fintech providers

Across all three countries, businesses choose between a traditional bank and a digital or fintech provider, but the balance differs by market. The US has the deepest fintech bench for business accounts; Canada and Mexico are catching up from a more bank-dominated base. The trade-offs are consistent: incumbents offer lending, branches and full services, while fintechs often win on onboarding speed, software and, for cross-border needs, multi-currency and FX.

A common pattern for an internationally active business is a US-dollar account as the regional hub, plus local accounts in Canada or Mexico where there is real activity, and a multi-currency provider to manage FX. As of 12 June 2026, the right mix depends on where revenue and costs sit and whether the business needs credit.

Credit access is one area where incumbents still hold an edge over fintechs. Business lending, credit cards, lines of credit and merchant services are typically deepest at established banks, which value the full relationship and the data a primary operating account provides. A business that expects to borrow, or to need cash-management and payroll services at scale, often keeps a traditional bank at the centre even if it uses a fintech for day-to-day spend and cross-border payments. As of 12 June 2026, weighing likely future credit needs alongside today's account costs helps avoid having to rebuild a banking relationship later.

Opening a business account: documents and steps

The sequence is similar across the region: form or register the entity, obtain the tax identifier, then open the account, after which the provider runs know-your-customer, beneficial-ownership and identity checks. The list below is representative; exact requirements vary by country, provider and entity type.

• Entity formation documents (articles of organisation or incorporation, certificate of registration).
• The business tax identifier: EIN (US), Business Number (Canada) or RFC (Mexico).
• Identification for owners, directors and authorised signatories.
• Beneficial-ownership information (US banks collect this under federal rules).
• Proof of business address and a description of the activity and expected turnover.
• For non-residents, additional verification and, with some banks, an in-person visit.

Fees, wires and FX

Fee structures differ by country and provider, but a few themes recur. In the US, many business accounts carry no or low monthly fees, especially online, but wire transfers (domestic and international), cash deposits and exceeding free-transaction limits cost extra. Canada and Mexico more commonly apply monthly account fees and minimum balances. Across all three, international payments carry both a fee and an FX margin, which is where costs add up for cross-border businesses. The ranges below are illustrative; confirm exact figures with the provider.

Payments and moving money across the region

How money actually moves differs by country and is worth understanding, because it affects both speed and cost. In the United States, the long-standing ACH network handles most low-cost domestic transfers but settles in batches rather than instantly, while wires move large sums quickly for a flat fee. Newer real-time rails, including the RTP network and the Federal Reserve's FedNow service, are expanding instant payments between US accounts, though adoption is still growing as of 12 June 2026. For a business, the practical point is that "fast" and "cheap" are not always the same product, so it pays to match the payment type to the need.

Canada relies on Interac for everyday transfers between accounts and is modernising its core payment systems toward real-time capability, while Mexico's SPEI system already provides widely used, near-instant interbank transfers. None of these domestic systems crosses borders on its own, so paying between the three countries still means an international transfer, with a fee and an FX margin, or a multi-currency provider that can hold and convert dollars, Canadian dollars and pesos more cheaply.

For companies whose supply chains span the USMCA bloc, this is where treasury planning earns its keep. Holding a US-dollar account as the regional hub, keeping local accounts where there is genuine activity, and using a multi-currency or specialist FX provider for conversions can cut the cost of routine cross-border payments meaningfully compared with sending every payment as a standard international wire. As of 12 June 2026, the right setup depends on payment volumes and which currencies dominate the business.

The non-resident and cross-border angle

North America, and the US in particular, is a major destination for non-resident founders, partly because a US entity and US-dollar account are useful far beyond the region. A non-resident typically forms a US LLC or corporation, obtains an EIN and then opens an account, increasingly through fintech providers that onboard remotely, though some traditional banks still prefer an in-person visit. Canada and Mexico also allow foreign-owned companies, but banking as a non-resident can be more involved, and local presence or a resident director often helps.

For businesses with activity in more than one North American country, a frequent approach is to anchor on a US-dollar account, add local accounts where there is genuine on-the-ground activity, and use a multi-currency provider to move between dollars, Canadian dollars and pesos efficiently. There is a dedicated guide on this site for forming and banking a US LLC, which is the most common entry point for non-residents. As of 12 June 2026, the path is well-trodden but depends on the provider, the entity and the quality of the owner's documentation.

Common pitfalls to avoid

A handful of recurring mistakes cause most of the friction for businesses banking in North America.

• Skipping the tax ID step. No EIN, Business Number or RFC usually means no account; get it first.
• Treating the region as one market. Currencies, regulators and rules differ; bank country by country.
• Ignoring wire and FX costs. Headline "free" accounts can still be expensive for cross-border payments.
• Assuming fintech deposits work like bank deposits. Confirm how and where funds are held and insured.
• Underestimating non-resident requirements. Remote opening is possible but varies by provider; plan documentation early.

Choosing how to bank in North America

The right approach depends on where the business operates and how international it is. A US-based company often starts with a low-fee online account or a national bank, adding lending relationships as it grows. A Canadian or Mexican business usually banks with a major national institution, weighing monthly fees against service and credit. A cross-border or non-resident business frequently centres on a US-dollar account, adds local accounts where it has activity, and uses a multi-currency provider to manage FX. As of 12 June 2026, weigh currency exposure, fees, tax-identifier requirements, deposit insurance and non-resident rules together, and confirm the current position with the specific provider before committing.
