USD business account in Mexico

USD business account options in Mexico: the short answer

A Mexican business has four ways to hold and receive US dollars: a dollar account at a Mexican bank, a USD account with a provider outside Mexico that accepts Mexican companies, a US company with its own US bank account, and, for some firms, a stablecoin wallet. Most companies that trade with the United States use a Mexican dollar account plus one of the other routes.

A Mexican company can keep a dollar balance at a local bank. Banco de México (Banxico), the central bank, allows Mexican banks to take US dollar demand deposits from any company domiciled in Mexico. A demand deposit is a current account balance that the holder can withdraw at any time, as opposed to a time deposit locked for a fixed term. The same rule is much narrower for individuals, which matters for freelancers and sole traders.

Each route answers a different need:

• Importers and wholesalers want dollars on hand to pay suppliers in the United States and Asia without converting pesos at each payment.
• Exporters want US buyers to pay quickly and in full, and want to choose when to convert to pesos.
• Agencies, software firms and other service businesses want US clients to pay them the way they pay a US vendor, by ACH or Fedwire.
• Trading companies buying and selling across borders often need all three.

This guide covers the Banxico rules on dollar accounts, which foreign providers say they accept Mexican businesses, the US company route, the documents banks ask for, the legal position of stablecoins such as USDC and USDT, and where a Helm USD account in your company's own name fits. For the payment details a US buyer needs and arrival times, see our guide to US dollar accounts for Mexican companies selling to US buyers.

The options compared

The table compares the option types. It is not a ranking. The right mix depends on who pays you, who you pay, and where your costs are.

SWIFT is the global messaging network banks use to send cross-border payments. The CLABE (Clave Bancaria Estandarizada) is the 18 digit standardized account number every Mexican bank account carries for interbank transfers. ACH is the US batch transfer network for lower-cost domestic payments, and Fedwire is the Federal Reserve's same-day wire system. A US buyer can use ACH or Fedwire only when the receiving account is in the United States.

How to choose

• If most of your dollars go out to suppliers, a Mexican dollar account plus a provider that sends international payments covers both sides without converting twice.
• If most of your dollars come from US customers, US account details in your company's name let them pay by ACH or Fedwire, with no correspondent bank in the chain.
• If you must pay other Mexican companies in dollars, keep a Mexican dollar account: dollar transfers between Mexican companies run on SPID, which is available only between dollar accounts at banks in Mexico.
• If your costs are in pesos, hold dollars and convert on your own schedule instead of letting a peso account convert each wire on arrival.

Banxico rules on dollar accounts in Mexico

Banxico sets the rules for foreign currency deposits at Mexican banks in Circular 3/2012, its main rulebook for the operations of credit institutions. Three articles govern a business dollar account.

Who can hold a dollar account (Article 46)

Article 46 allows banks to receive foreign currency demand deposits, with or without a checkbook, payable in Mexico, from three groups only: companies (personas morales) domiciled in Mexico; individuals living in towns within a strip 20 kilometers wide along the northern border, or in Baja California or Baja California Sur; and foreign official missions, international organizations, their foreign staff and accredited foreign correspondents. The bank may open the account only after the customer proves with documents that it belongs to one of these groups, and it must keep that proof on file.

Article 46 also covers time deposits payable abroad. Only companies domiciled in Mexico can hold them.

How money goes in and out (Articles 47 and 48)

Article 47 lists how a dollar account can be credited, including electronic transfers of funds denominated and payable in foreign currency. Article 48 lists how it can be debited, including electronic transfers in foreign currency. In practice this means a US buyer's wire lands as dollars, and the company can send those dollars on to a supplier abroad by wire without converting them.

Dollar payments inside Mexico: SPID

SPID (Sistema de Pagos Interbancarios en Dólares) is the interbank system for US dollar transfers between dollar accounts at banks in Mexico. Banamex, for example, offers SPID only to companies incorporated under Mexican law and domiciled in Mexico, and excludes individuals, sole proprietors, trusts and foreign companies. Its customers need a valid FIEL, the advanced electronic signature certificate issued by the tax authority SAT. Banamex runs SPID transfers through its BancaNet Empresarial platform from Monday to Friday, 8:00 to 17:00, and not on Mexican banking holidays.

Paying a supplier in China or the United States from a Mexican dollar account is an ordinary international wire. Our guide on paying suppliers in Mexico covers the same corridor from the US buyer's side.

Foreign USD account providers and Mexico

Many Mexican businesses add a USD account held outside Mexico so US customers can pay by ACH or Fedwire. Eligibility is set by each provider. The table records what each provider states on its own pages; it is not a ranking.

Payoneer's page also lists an annual account fee of 29.95 USD when an account receives less than 6,000 USD in any 12 consecutive months, and 1.2% to 4% to withdraw to a bank account in a non-local currency with conversion.

Before you apply to any provider, check three points:

1. Whose name is on the details. Some providers issue details in your company's own name; others credit you from a pooled account in the provider's name, which some US buyers' payment teams query.
2. Which rails the details accept. ACH only, or also Fedwire and incoming SWIFT from buyers outside the United States.
3. How dollars reach Mexico. If you need them in your Mexican dollar account, the transfer is an international wire into an account that accepts foreign currency transfers under Article 47.

The US company route

Some Mexican groups form a US company, usually a limited liability company (LLC) or a corporation, and open a US account in its name. Mercury, for example, requires the company to be formed and registered in the United States or a US territory, and states that founders do not need to be US citizens or residents. Mercury also publishes a list of countries and regions whose founders it cannot support, so check it before forming the company.

The US company needs an Employer Identification Number (EIN), the US federal tax number for a business. The IRS instructions for Form SS-4 state that applicants with no principal place of business in the United States may call 267-941-1099 (not a toll-free number) from 6:00 a.m. to 11:00 p.m. Eastern Time, Monday to Friday, and that only international applicants can receive an EIN by telephone. Applicants outside the United States can also fax Form SS-4 to 304-707-9471.

A US company makes sense when you have real US operations, such as a warehouse, staff or a US sales contract that requires a US counterparty. If you only need US customers to pay you easily, USD account details in the Mexican company's own name achieve that without a second company.

Documents you need

Banks and providers ask for broadly the same company file. Banamex's published list for its business dollar checking account (Cuenta de Cheques en Dólares) is a useful reference: an opening amount of 1,000 US dollars; articles of incorporation registered with the Registro Público de la Propiedad y Comercio, or a notarized letter stating registration is in process; notarized powers of the legal representatives; the company's RFC; valid official ID for representatives and signatories; and proof of address for the company and for each representative, no older than three months.

Sources: Banamex, Cuenta de Cheques en Dólares and Banamex, SPID; other rows are typical requirements compiled by the Helm Editorial Team and vary by bank and provider. As published on 29 October 2026.

Use the registered company name, exactly as it appears in the acta constitutiva, on every application and invoice. A trading name on one form and the registered name on another is a common cause of delay, and so is a proof of address that has passed three months.

Stablecoins in Mexico: USDC and USDT

Stablecoins are digital tokens designed to hold a steady value against a currency such as the US dollar. USDC and USDT are the two most widely used dollar stablecoins. Two Mexican sources set the position for regulated institutions.

• The Fintech Law. Article 30 of the Ley para Regular las Instituciones de Tecnología Financiera defines a virtual asset as a representation of value recorded electronically, used as a means of payment and transferable only electronically. It states that legal tender in Mexico, foreign currencies and any other asset denominated in them are never virtual assets. Fintech institutions may operate only with virtual assets that Banxico determines, and need Banxico's prior authorization. Article 34 requires those institutions to tell clients that a virtual asset is not legal tender and is not backed by the Federal Government or Banxico, that transactions may be irreversible, and that its value can be volatile.
• Banxico Circular 4/2019. Published on 8 March 2019, it applies to banks and authorized fintech institutions. They may carry out operations with virtual assets only as internal operations, with Banxico's prior authorization, and must prevent the risk passing to their clients. Applications to offer clients exchange, transfer or custody of virtual assets directly are not eligible for authorization.

These rules regulate Mexican banks and fintech institutions. They mean a Mexican company will not get USDC or USDT services from its Mexican bank. A company that is paid in stablecoins by a customer abroad uses a provider outside the Mexican banking system and converts to dollars there. Take Mexican tax and legal advice on how those receipts are recorded.

Where a Helm USD account fits

Helm is a financial technology company, not a bank. Accounts are held with regulated partner institutions. Helm provides USD account details in your company's own name, with a US routing and account number that receives ACH, Fedwire and SWIFT payments, alongside EUR and GBP details. Helm can serve businesses in Mexico.

For a Mexican business, it sits beside the Mexican dollar account, not instead of it:

• Exporters and service firms can give US customers domestic US payment details, so a customer pays by ACH or Fedwire as it would pay a US vendor. Collections can be held in USD or converted.
• Importers and wholesalers can send international payments to suppliers by SWIFT, or by local rails in the supplier's currency where available, with the rate, fee and expected arrival shown before sending.
• Companies paid in stablecoins can receive USDC and USDT and convert them to USD inside the account.
• Companies that pay other Mexican firms in dollars keep their Mexican dollar account for SPID.

Each account has a named account manager, and review questions are answered in writing within one business day. Trade finance, such as supplier finance, receivables finance and working capital, is arranged case by case. Helm agrees pricing with each business in writing before the account opens, and shows the rate, the fee and the expected arrival before you confirm each payment.

Freelancers and sole traders

Individuals face a tighter rule than companies. Under Article 46 of Circular 3/2012, a Mexican bank can open a dollar demand account for an individual only if the person lives within 20 kilometers of the northern border or in Baja California or Baja California Sur. A freelancer in Mexico City, Guadalajara or Monterrey does not fit that group, even if registered with SAT as an individual with business activity. Banamex's SPID service also excludes individuals and sole proprietors.

That is why many Mexican freelancers paid by US clients use a USD account with an online provider. Check eligibility on the provider's own page before you apply, and note that some providers accept only registered companies. A freelancer who grows into an agency should incorporate, open a dollar account in the company's name and move client payments there, so business and personal funds stay separate. Freelancers in Colombia face different rules; compare them in our guide to USD business accounts in Colombia.
