Card payments from customers worldwide
Stripe already supports Mexican businesses. A US LLC's income can be taxed as yours in Mexico anyway, so a US company needs a reason.
From Mexico · The Americas
For Mexican founders who want to sell to US customers as a US vendor, hold a US-facing brand or raise from US investors. You already have Stripe, and founders here can apply to Mercury, which decides each application. Mexico can tax a single-owner LLC's income as yours each year, so read that section first.
Launch + Wyoming filing; the tax return is separate.Checked by Saais Patel, compliance reviewer.
At a glance
Mercury takes applications from founders living in Mexico. Wise gives no USD account details there.
The banks, in detailYou can form a US LLC while living in Mexico, without an SSN or a US visit, and founders here can apply to Mercury, which decides each application. Launch starts at $351.40 in Wyoming, including our plan and state filing fee. Stripe already serves Mexico, so the reason is usually US customers or investors. The catch is SAT: income through a see-through US LLC can be taxed as yours each year, and low-taxed foreign income is taxed when earned.
Before you form
Wyoming LLC
Owner-run business selling to US customers; income likely yours for SAT.
Delaware C-Corp
Raising from US investors; check the 75% test.
Both charges are the state's, before our plan, optional services and your advisers' fees. Wyoming sets a minimum yearly charge, and Delaware's franchise tax depends on how it's calculated. Staff, stock or premises in another state can bring obligations there. An S-corporation isn't an option, because nonresident aliens can't hold its shares.
Prepare the information
You don't need a Mexican company to form a US LLC. The EIN is the US company's tax ID. Send identity documents through a secure request, and only the ones asked for.
How it works
The state approves the company, the IRS issues the EIN and each provider approves its own account. In Mexico, your accountant handles SAT; we don't file there.
You and your accountant
Decide whether you need a US company at all, whether an LLC or a C-Corp suits SAT's rules for you, and where it will be managed.
You leave this stage with: A structure and tax plan that fits Mexico's rules.
You choose; BaseAcross checks
We check the proposed name and provide the registered agent in the formation state. The registered office is for legal papers, not your operating address.
You leave this stage with: Confirmed filing details and a registered agent.
BaseAcross files; the state approves
We submit the formation filing and send you the state's documents once it's approved. The company exists from that approval.
You leave this stage with: State-approved formation documents.
BaseAcross
We draft the LLC Operating Agreement or corporate bylaws. Check every name and share against your passport before you sign.
You leave this stage with: Operating documents for your records, your bank and US providers.
BaseAcross prepares; the IRS issues
The EIN is a separate application after formation. Without an SSN or ITIN, it goes on Form SS-4 rather than the IRS's online tool.
You leave this stage with: The IRS's EIN confirmation once it's issued.
You apply; the providers review
Start with Mercury, which opens for founders living in Mexico. Wise won't give you USD account details. Use the same names, addresses and business description everywhere.
You leave this stage with: An approved account, if a provider accepts the application.
You, your US preparer and your accountant
Keep the company's books in a form that maps to Mexican rules, and record every payment to you. Put Form 5472 and your SAT return on one calendar.
You leave this stage with: A yearly calendar with someone responsible for each filing.
Plan the wait
Published service estimates and prerequisites for a Wyoming company from Mexico
These are service estimates, not promised completion dates. The IRS and each provider set their own processing times. Names or addresses that differ between documents slow every stage.
What it costs
Charged in US dollars, with the Wyoming state fee passed on at cost. Where you live changes which bank we introduce you to, not the price.

Federal filing responsibilitiesQuote from your accountant
How SAT treats the LLC or C-Corp, and what you file, depend on your circumstances.
Published in full pricing
Check domain renewals and when Launch's email, phone and site trials end. Operate includes its stated tools while subscribed.
Plans, trials and add-onsThe $309 Launch renewal example is the $249 plan renewal plus Wyoming's $60 minimum license tax. Wyoming charges the greater of that minimum or 0.0002 of the company's assets located and employed in the state, and paying online can add a processor fee. The Operate example uses the same minimum.
Prices are in US dollars. Paying from Mexico, check your card's exchange rate and fees.
Use the first-year cost calculator to compare plans and optional tools. Then add your accountant's fees and US return preparation to that budget.

1 of 4: The tax treaty
The tax treaty
The US–Mexico income tax treaty is in force.
It caps US withholding on most interest at 15%, on dividends at 10%, or 5% for a qualifying company shareholder, and on royalties at 10%. Pay for work you do in Mexico generally isn't US-source income, so the treaty matters less for a services business.
How SAT sees it
These come from PwC's summaries of Mexico's Income Tax Law and Federal Tax Code, and they run alongside the US steps below. Which applies depends on the structure you choose.
You and your accountant
Income through a foreign transparent entity is taxed as your own, under your own regime, as it's earned.
You and your accountant
If its income is untaxed or taxed at less than 75% of the Mexican tax, it's a preferential regime, taxed in Mexico when earned.
You
Fully taxable in your annual return, at up to 35%, plus 10% of the net dividend by the 17th of the next month.
You and your accountant
A principal centre of administration or effective place of management in Mexico makes the company resident.
You
Credit any foreign tax up to the Mexican tax on the same income; none for income Mexico exempts.
Worked example
This is an illustration, not advice. Your accountant confirms SAT's treatment of your LLC.
Your Wyoming LLC earns USD 60,000 of profit from clients worldwide, and you do the work in Mexico.
With no US office or staff, it usually owes no US income tax on that profit.
For SAT, the LLC is see-through, so the USD 60,000 is likely your own income for the year.
With no US tax paid, there's nothing to credit. Your accountant applies your regime's rates.
What Mexico expects
Mexico taxes residents on worldwide income, taxes income through a see-through foreign entity as the owner's own, and taxes low-taxed foreign income when earned. Plan the structure with an accountant who knows both.
Income a Mexican resident earns through a foreign transparent entity is taxed as the resident's own income, under their own regime. A single-owner US LLC is transparent for US tax, so ask whether SAT taxes its income as yours each year.
Income is under a preferential tax regime when it's untaxed abroad or taxed at less than 75% of what Mexico would charge. It's then taxed in Mexico when earned, even if nothing is paid out.
Dividends from a foreign company are fully taxable in your annual return, at rates up to 35% in 2026. A further 10% on the net dividend is due by the 17th of the next month, and it can't be credited.
A company is resident in Mexico if its principal centre of administration or effective place of management is there, wherever it was formed.
You're resident if your home is in Mexico. With a home elsewhere too, it's where your centre of vital interests is: more than half your income from Mexico, or Mexico as your main place of work. Foreign tax is credited only up to the Mexican tax on that income.
On the record
We form US companies. We aren't Mexican tax advisers. These are the rules as they're generally published, they change, and how they apply to you depends on details this page can't know. Take this list to a tax adviser in Mexico before you order, and we'll tell you what the US forms need.
After formation
A US LLC with one foreign owner is usually a disregarded entity that files Form 5472 with a pro forma Form 1120 when it has reportable transactions with you. Money you put in, take out or are paid for your work can count even in a year without sales. The IRS penalty for not filing starts at $25,000.
For a calendar-year company, the return is usually due 15 April, and Form 7004 requests an extension before then. A C-Corp, or an LLC with more than one owner, files different returns.
Form 5472 and the pro forma 1120Keep the registered agent active and track the state's yearly charge. In Mexico, file your annual return with the company's income in it, and any information return your accountant says the structure needs.
US-created companies are exempt from BOI reporting under FinCEN's current rule, effective 14 August 2026. Banks and payment providers still verify who owns the company.
| Task | Who handles it | Where the responsibility ends |
|---|---|---|
| Formation and EIN application | BaseAcross prepares and submits | The state approves formation; the IRS issues the EIN. |
| Bank and payment applications | You, with our guidance | The provider verifies the information and decides. |
| SAT returns and information returns | You and your accountant | We provide the US company records they need. |
| Annual state filing | You, or our optional filing service | Reminders are included; managed filing and the state charge are separate. |
| US federal returns | You and your US tax preparer | Launch and Operate remind you; they don't file the return. |

Questions
If yours is not here, email us at hello@baseacross.com before you order.
Yes. US law doesn't require an LLC's owners to be US citizens or residents, and formation, the EIN and the bank applications all happen remotely. Owning a US company doesn't give you a US visa, and it doesn't take your income out of Mexico's reach.
It can. Income a Mexican resident earns through a foreign transparent entity is taxed as the resident's own income. A single-owner US LLC is transparent for US tax, so expect its income to count as yours each year. Your accountant confirms how SAT treats it.
It's Mexico's preferential tax regime rule. Income is caught when it's untaxed abroad or taxed at less than 75% of what Mexico would charge. Caught income is taxed when earned, even if nothing is paid out to you.
They're fully taxable in your annual return, at rates up to 35% in 2026. A further 10% on the net dividend is due by the 17th of the following month, and it can't be credited.
Launch starts at $351.40: $249 for the plan plus $102.40 for the Wyoming filing. The plan and Wyoming's minimum yearly charge then total $309 a year. Your accountant's fees, US return preparation and your SAT filings are separate. Wyoming's license tax can be more than its $60 minimum.
A Wyoming LLC usually suits an owner-run business selling to US customers, and SAT may tax its income as yours. A Delaware C-Corp suits raising from US investors. Nonresident aliens can't hold shares in an S-corporation.
Yes. Without an SSN or ITIN, the application goes on Form SS-4 instead of the IRS's online tool. We prepare it after the company is formed, and the IRS issues the number.
Each stage has its own clock. Wyoming's published turnaround is same day once a complete filing is accepted. Our ordinary EIN estimate is six to eight weeks after the application, or two to three weeks with the $199 expedited option. Banks, payment providers and Stripe each set their own review times. These are estimates, not promises.
Usually you can apply. Mexico isn't on Mercury's list of countries it doesn't serve, and the list goes by where you live. Mercury still reviews each company and can decline.
Not for USD account details. Wise gives no USD details to founders living in Mexico, which isn't on its list of places where people can hold money. Relay doesn't bar Mexico, but it asks every owner for a physical US address.
No. Stripe supports businesses in Mexico. A US company is for selling as a US vendor, US contracts, US investors or platforms that need one.
Generally not. Pay for work you do in Mexico is generally not US-source income, so a single-owner LLC with no US office or staff often owes no US income tax on it. It still files Form 5472 with a pro forma Form 1120 when it has reportable transactions with you.
Yes, it's in force. It caps US withholding on most interest at 15%, on dividends at 10%, or 5% for a qualifying company shareholder, and on royalties at 10%. Mexico credits foreign tax only up to the Mexican tax on that income.
It can. A company is resident in Mexico if its principal centre of administration or effective place of management is there. A US company you run day to day from Mexico City should have an accountant look at this.
On Launch and Operate, we add deadlines and reminders; you or your accountant file the federal returns. Managed annual state compliance is an optional $149 service fee a year, with the state's charge separate. Your SAT returns and any information returns are for you and your accountant.
US-created companies are exempt under FinCEN's current BOI rule, effective 14 August 2026. A company formed outside the US and registered to do business there is a different case. Banks still collect ownership details for their own checks.
