Register a US company from Mexico, without leaving home.
Formation, EIN without an SSN, US bank-account guidance, and the Mexico–US tax treaty — the whole US setup run remotely by a CPA firm, so your e-commerce and marketplace business can invoice, sell, and settle in dollars from just across the border.
For a Mexican seller, a US company is the bridge from peso-denominated domestic rails to dollar-paying US customers and marketplaces.
Mexican founders reach us from two directions that meet in the same place. Manufacturers and IMMEX-registered businesses that spent years assembling for export are now selling direct-to-consumer on Amazon and Walmart.com, and they need a clean US-facing entity to do it. And domestic sellers whose entire payment world is SPEI transfers and OXXO cash vouchers find that none of those rails reach a US buyer — Stripe, US card processing, and US marketplace payouts all expect a US company with a US bank account behind them.
Proximity makes the leap smaller than it looks. The peso is steadier than many emerging-market currencies, but earning and holding revenue in dollars still removes a conversion you don't control, and a US presence is often a natural extension for a business already selling north of the border. Our job is to build it so marketplace verification goes smoothly and the compliance calendar stays handled while you focus on product and sourcing.
The full US setup, from Mexico
The same spine we run for every international founder, adapted to how Mexican sellers and manufacturers operate.
Entity & state choice
A single-member LLC is the usual fit for a seller or D2C brand; a Delaware C-Corp is for founders raising US capital. We match the state — commonly Wyoming, Delaware, or Florida — to how you'll operate. Weighing the options? Our US company cost calculator compares filing and annual costs.
EIN without an SSN
Without a US Social Security Number, the IRS online tool is closed to you, so the EIN goes through Form SS-4 by fax — roughly 10 to 14 days or more as of 2026. We prepare and submit it and track it to issuance; here's how getting an EIN without an SSN actually works.
US bank account, remotely
Options such as Mercury, Wise, Payoneer, and Relay let founders in Mexico open US business banking without flying over. We prepare your documentation so the application meets the bank's checks — more on opening a US business bank account as a non-resident. The bank makes the final call.
Mexico–US tax treaty
Mexico and the United States have an income tax treaty in force. It provides a framework to avoid double taxation and can reduce US withholding on certain payments. We factor it into your structure and your W-8BEN/W-8BEN-E paperwork from the start rather than treating it as an afterthought.
Form 5472 & annual duties
A foreign-owned single-member LLC must file Form 5472 with a pro-forma 1120 every year, even with no activity — the form that carries a $25,000 penalty if missed. We set the calendar and file on time, alongside your state annual report.
Marketplace KYC consistency
Amazon and other marketplaces verify that your entity name, EIN, address, and banking match across every record. We keep those details consistent from day one so verification doesn't stall your seller account.
What tends to matter for founders in Mexico
A few realities specific to setting up from Mexico, so there are no surprises.
From SPEI and OXXO to dollar settlement
SPEI and OXXO run your domestic collections, but neither reaches a US customer or a US marketplace payout. A US entity with the right bank and processor lineup lets dollars settle to an account you control, so you convert to pesos on your own timing instead of at whatever rate a payout happens to hit.
IMMEX and maquila sellers going direct
Manufacturers moving from export-assembly work to direct-to-consumer selling have a foot in two systems. We set up the US selling entity so it sits cleanly alongside your Mexican operations rather than tangling with them, and so the marketplace sees a consistent US business.
Register truthfully as a foreign owner
The common trap is claiming a US operational address you can't back with a utility bill. Being close to the border doesn't change that — it's cleaner to register truthfully as a foreign-resident owner, and we set the entity and records up that way so a marketplace's checks don't rebound on you.
Whether US income tax is actually owed
A US company doesn't automatically mean a US income tax bill. Whether your income is effectively connected to a US trade or business, read together with the Mexico–US treaty, drives what's owed. We run that analysis instead of assuming an answer in either direction.
Questions from founders in Mexico
General information to help you plan. Your specifics may differ — that's what the first conversation is for.
Is there a Mexico–US tax treaty?
Yes. Mexico and the United States have an income tax treaty in force. It provides a framework to avoid the same income being taxed twice and can reduce US withholding on certain cross-border payments. Whether it applies to you depends on your structure and where the activity happens, and we build that into your setup and filings.
Do I need to visit the US to register the company from Mexico?
No. Founders in Mexico can form and run a US company entirely from home. Formation needs your passport, not travel or a US visa. We file everything remotely and coordinate the steps that touch a US institution, such as the bank application.
Can I keep my marketplace earnings in dollars?
Yes. With a US entity and a US business account, your marketplace and processor payouts can land and stay in dollars instead of being converted at each settlement. You decide when and how much to move to pesos, which gives you control over timing rather than converting automatically on every payout.
How does marketplace verification work from Mexico?
Amazon and other marketplaces verify that your entity name, EIN, address, banking, and tax interview all match, and that you register truthfully as a foreign-resident owner rather than claiming a US operational address you can't document. We set your records up consistently from the start so verification is a formality, not a weeks-long stall.
