To send money to a Mexican bank account, you need the recipient’s full legal name as it appears on their bank records and their 18-digit CLABE number, plus the receiving bank’s SWIFT code if you’re using a traditional bank wire. From there you choose a channel — a bank wire, an online transfer platform, or a retail money transmitter — and most electronic transfers settle in seconds through Mexico’s SPEI network, while bank wires routed through SWIFT typically take one to three business days.
What You Need From the Recipient
Start with the recipient’s full legal name, exactly as their Mexican bank has it on file. Mexican naming conventions use two surnames, the father’s followed by the mother’s, and dropping either one gives the receiving bank a reason to reject the deposit. Banks match recipient names against their records under anti-money laundering rules, so even a small discrepancy can hold funds in transit.1FFIEC BSA/AML Manual. Assessing Compliance with BSA Regulatory Requirements – Special Information Sharing Procedures
The second essential piece is the Clave Bancaria Estandarizada, or CLABE: an 18-digit number assigned to every bank account in Mexico that routes money to the correct institution, branch, and account.2Banco de México. SPEI, Information, Banco de México Your recipient can find it on a monthly bank statement or inside their mobile banking app under account details.
For a traditional bank wire, you’ll also need the receiving bank’s SWIFT code (sometimes called a BIC), an eight- or eleven-character identifier used on the global SWIFT messaging network. Including the bank’s name adds another verification layer. Confirm every digit before you submit. A wrong CLABE or SWIFT code can misroute funds or park them in a clearinghouse for days.
Three Ways to Send the Money
A traditional bank wire moves funds directly from your U.S. checking or savings account to the Mexican institution through the SWIFT network, often passing through one or more intermediary banks along the way. Each intermediary adds time and usually cost, which makes bank wires the standard choice for large, formal transfers but a pricey option for smaller amounts.
Online transfer platforms (fintech services) hold their own balances in both countries. When you send, they collect your dollars in the U.S. and release pesos from their Mexican holdings, which lets them skip some of the intermediary steps and generally offer tighter exchange rates.
Retail money transmitters work through physical storefronts and online portals and specialize in high-volume personal transfers. They connect directly into the Mexican banking network to deposit funds straight into the recipient’s account, and they’re often the most accessible option if you don’t have a U.S. bank account.
What It Will Actually Cost
Costs come from two places, and most people only see one. The visible cost is the flat fee: outgoing international wires from a U.S. bank typically run $15 to $50, and some digital platforms charge little or nothing for standard-speed transfers.
The less visible cost is the exchange rate markup. Every provider converts your dollars to pesos at a rate that differs from the mid-market rate you see on a search engine or financial news site, and the gap is their margin. Traditional banks and legacy wire services tend to apply wider markups than dedicated transfer platforms. On a $1,000 transfer, even a 2% markup costs $20 on top of the flat fee. Compare the total pesos the recipient will receive, not the advertised fee.
Federal law gives you a tool for that comparison. For any remittance over $15, the provider must show you the exchange rate, all fees and taxes, and the exact amount the recipient will receive in pesos before you pay.3eCFR. 12 CFR 1005.31 – Disclosures If a “no fee” transfer delivers fewer pesos than a $5 competitor, the markup is eating the difference.
Running the Transfer
With the name, CLABE, and SWIFT code (if needed) in hand, log in to your chosen service or visit a branch. Online services ask you to select an international transfer to Mexico. At a physical location, you’ll show government-issued identification before anything else.4FFIEC BSA/AML Manual. Assessing Compliance with BSA Regulatory Requirements
Enter the recipient’s details and the amount in either dollars or pesos. The provider must then show the pre-payment disclosure: exchange rate, fees, taxes, and the final peso amount the recipient will receive.3eCFR. 12 CFR 1005.31 – Disclosures Review those numbers before you authorize payment. The disclosure has to appear first, so you have a real chance to walk away.5eCFR. 12 CFR Part 1005 – Electronic Fund Transfers (Regulation E)
After you confirm and pay, the system generates a transaction reference number, sometimes called a folio. Keep it. That number is your proof of the request and the key to tracking, cancellation, and any dispute later on.
How Fast It Arrives
Speed depends almost entirely on whether the transfer uses SPEI, Mexico’s real-time payment system. SPEI is operated by Banco de México and settles payments between bank accounts in seconds.2Banco de México. SPEI, Information, Banco de México Most digital platforms and many retail transmitters use SPEI for the final leg, which is why they can promise delivery in minutes. Mobile banking SPEI transfers run 24 hours a day, every day of the year; internet banking SPEI transfers run during standard Mexican banking hours on business days.6Banco de México. SPEI, Información, Banco de México
Traditional bank wires routed through SWIFT intermediaries typically take one to three business days, because each intermediary runs its own compliance checks before passing funds along. Banking holidays in either country can stretch that window further.
Mexico observes several banking holidays in 2026 when SPEI and bank clearing systems are closed: January 1, the first Monday of February, the third Monday of March, April 2 and 3, May 1, September 16, November 2, the third Monday of November, and December 12 and 25.7Banco de México. 2026 Bank Holidays Transfers landing on those dates can expect an extra day or two of delay unless they’re going through mobile SPEI.
To confirm delivery, enter the transaction reference number in the provider’s tracking portal. For SPEI payments, you can also pull a Comprobante Electrónico de Pago (CEP) from Banco de México’s website. The CEP carries a digital seal you can verify, which makes it definitive proof the funds reached the destination account.2Banco de México. SPEI, Information, Banco de México
If Something Goes Wrong
Regulation E, which implements the Electronic Fund Transfer Act, protects you on remittances over $15 to another country, whether they go through a bank, a digital platform, or a retail transmitter.8eCFR. 12 CFR 1005.30 – Remittance Transfer Definitions
The most useful protection is the cancellation right. You can cancel a remittance at no cost within 30 minutes of making payment, as long as the recipient hasn’t already picked up or received the funds. The provider must refund the full amount, including all fees and applicable taxes, within three business days.9eCFR. 12 CFR 1005.34 – Procedures for Cancellation and Refund of Remittance Transfers This is where catching a wrong CLABE or misspelled name early really matters.
After the 30-minute window, you have 180 days from the disclosed delivery date to report an error to the provider. Errors include the wrong amount arriving, funds going to the wrong account, or the recipient never getting the money. The provider then has 90 days to investigate and must report findings to you within three business days of finishing.10eCFR. 12 CFR 1005.33 – Procedures for Resolving Errors
Mexico’s Limits on Cash Dollar Deposits
Mexico restricts how many U.S. dollars can be deposited in cash at a bank branch, as part of its anti-money laundering framework. These limits apply to physical cash transactions, not to electronic wire transfers, so if you’re sending money straight into the recipient’s account they won’t affect your transfer. They matter only if your recipient plans to walk into a branch with dollar bills.
Account holders can deposit no more than $4,000 USD in cash per month across all branches of their bank. Mexican citizens who aren’t account holders at that bank face $300 per day and $1,500 per month. Tourists who aren’t account holders can exchange no more than $1,500 per month in cash.11Privacy Shield. Mexico – Foreign Exchange Controls Electronic transfers through online banking aren’t subject to these caps.
U.S. Reporting If You Hold or Heavily Fund the Account
Sending money to Mexico doesn’t create a tax bill on its own, but holding a foreign bank account or moving large amounts can trigger federal reporting obligations with sharp penalties for ignoring them.
FBAR (FinCEN Form 114)
If you have a financial interest in or signature authority over Mexican bank accounts whose combined balances topped $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts, or FBAR.12Financial Crimes Enforcement Network. Reporting Maximum Account Value The filing deadline is April 15 of the following year, with an automatic extension to October 15 if you miss it — no request needed.13Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) FBARs are filed electronically through FinCEN’s BSA E-Filing system, not with your tax return. Non-willful failure to file can bring a penalty of up to $10,000 per violation. Willful violations carry much more: the greater of $100,000 or 50% of the account balance at the time of the violation.
Form 8938 (FATCA)
Separately, the Foreign Account Tax Compliance Act requires some taxpayers to file Form 8938 with their tax return. For U.S. residents filing single, the thresholds are more than $50,000 in total specified foreign financial assets on the last day of the tax year, or more than $75,000 at any point during the year. Married couples filing jointly get higher thresholds of $100,000 and $150,000.14Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets Failing to file triggers a $10,000 penalty, plus another $10,000 for every 30 days of continued non-compliance after an IRS notice, up to $50,000.15Internal Revenue Service. International Information Reporting Penalties
You can owe both the FBAR and Form 8938 for the same account. They’re administered by different agencies, FinCEN and the IRS, with different thresholds and filing mechanisms.
Gift Tax
If the money is a gift rather than payment for goods or services, the 2026 annual gift tax exclusion is $19,000 per recipient.16Internal Revenue Service. Whats New – Estate and Gift Tax You can send up to that amount to any number of individuals without filing a gift tax return. Over $19,000 to a single person in a calendar year, you file Form 709, though you likely won’t owe tax because of the lifetime exemption. The recipient in Mexico owes no U.S. tax on the gift regardless of amount.
Cash Over $10,000 and Structuring
If you fund a transfer with more than $10,000 in cash at a bank or money transmitter in a single business day, the institution must file a Currency Transaction Report with FinCEN.17Financial Crimes Enforcement Network. Frequently Asked Questions Regarding FinCEN Currency Transaction Report (CTR) The institution files it, not you. Deliberately splitting a large transaction into smaller amounts to stay under the threshold, called structuring, is a federal crime even if the underlying money is entirely legitimate.
