Wyoming LLC from Mexico City

If you build, freelance, or run an agency from Mexico City and most of your invoices already read "USD," a Wyoming LLC gives you the clean US entity, US bank account, and US billing rails your clients expect — for $397 all in, formed in about 24 hours, with the Wyoming state fee already included.

Why Mexico City founders form a Wyoming LLC

Mexico City — CDMX to locals — is the second-largest business hub in North America after New York, and the proximity is not just geographic. The city's tech and services economy runs heavily on US demand. Colonia Roma, Condesa, and the Polanco-Reforma corridor are full of dev shops, design studios, marketing agencies, and remote engineers whose primary client base sits in Texas, California, and New York. The nearshoring wave of the last few years pushed even more of this work toward CDMX, where a same-time-zone (or one-hour-off) workforce bills US companies directly.

The friction shows up at the money layer, not the work layer. When a US client wants to pay a "Mexican vendor," their accounts-payable team often hesitates: foreign wire, W-8 paperwork, longer settlement, and FX questions. When that same client can pay a US LLC with a US EIN and a US bank account, the invoice clears like any domestic vendor. For a CDMX agency closing five-figure monthly retainers, that difference decides whether you win the contract.

The second driver is the platform layer. Stripe does not offer full local acquiring to individuals in Mexico the way it does to US entities, and many SaaS marketplaces, ad networks, affiliate programs, and app stores pay out cleanly only to US bank accounts. A Wyoming LLC with a US account on Mercury or Wise unlocks Stripe US, Stripe Atlas-style payouts, US PayPal, and the long tail of platforms that quietly treat "US entity" as the default.

Wyoming specifically — rather than Delaware — fits the CDMX freelancer and bootstrapped agency. Wyoming has no state corporate income tax, no franchise tax, strong privacy (members are not listed in public filings), and an annual report fee of roughly $60 versus Delaware's $300+ franchise tax. According to the Wyoming Secretary of State, the annual report is a flat license tax based on Wyoming-located assets, which for a non-US founder with no Wyoming assets stays at the minimum. Unless you are raising venture capital on a Delaware-C-corp track, Wyoming saves you several hundred dollars a year for the same legal substance.

There is also a workflow reason CDMX founders prefer the US entity over keeping everything under a Mexican structure. Running revenue through an SA de CV or even an RFC-registered persona física with full activity means monthly contabilidad electrónica, CFDI invoicing through SAT, and a contador on retainer — overhead that makes sense once you have Mexican operations and staff, but is pure friction when your customers are all in the US and just want to pay an invoice. The Wyoming LLC lets you keep the US-facing commercial layer simple and US-native, while your Mexican tax life stays on your personal return. You are not replacing your Mexican setup; you are adding the cleanest possible front door for dollar revenue.

Cost from Mexico City

Everything to get a working US entity is in the formation fee. The Wyoming state filing fee is included — there is no surprise line item.

So the real picture is $397 in year one, then about $160/year to keep the LLC in good standing. The ITIN is a separate $297 add-on and most CDMX founders do not need it — you get an EIN for the company regardless, and an ITIN is only relevant in narrow personal-tax situations. Compared with the Mexican cost of standing up an SA de CV or even an RFC-registered persona física with full contabilidad and a monthly contador, the Wyoming LLC is dramatically lighter to run.

Banking from Mexico City

This is where most CDMX founders have questions, so here is the honest version. There are three realistic options after your LLC and EIN exist: Mercury, Relay, and Wise Business.

Mercury remains the most popular full US business account for non-resident founders, and Mexican profiles are among the stronger ones it sees — clean documentation and a clear business description push approval to roughly three-in-four applicants. That said, Mercury tightened its non-resident reviews through 2025. As industry guides note, newly formed entities with no revenue, vague business descriptions, or applications that list a registered-agent address as the principal place of business are getting flagged or rejected more often. The fix from Mexico City is straightforward: use your real CDMX residential address as the principal place of business (Mercury allows a residential address; it does not allow a P.O. box or the registered agent's address), and write a specific, concrete description of what you sell and to whom.

Relay is the strongest backup and works well for non-residents who want multiple accounts and sub-accounts for budgeting. Wise Business is the easiest to get approved and doubles as your FX engine — and for a CDMX founder, that FX layer is the real value. Wise is technically an Electronic Money Institution, not a bank, but it gives you US account and routing numbers plus the cheapest USD-to-MXN conversion you will find anywhere.

A practical sequencing tip: apply to Mercury first because it is the fullest US business account, but open Wise Business in parallel rather than waiting. Wise approves quickly, gives you immediate USD receiving details so you can start invoicing the day your EIN lands, and serves as a guaranteed fallback if Mercury's review drags. Many CDMX founders end up keeping both — Mercury as the primary operating account and Wise as the dedicated FX and peso-payout rail. Whatever you do, do not apply with thin or inconsistent information; mismatched names between your formation docs, EIN letter, and bank application are a common cause of delays for non-resident applicants.

Here is how the US account complements your local Mexican rails rather than replacing them. You keep billing US clients in USD into Mercury or Wise. When you need pesos — to pay yourself, cover rent in Condesa, settle a Mexican supplier, or pay a local contractor — you move USD to MXN through Wise at the mid-market rate and land it in your Mexican bank via SPEI, Mexico's instant interbank transfer system. SPEI settles in seconds and is how Mexican banks and CoDi work locally; the LLC's job is to capture and hold the USD upstream so you control exactly when and how much you convert, instead of letting a US client's bank or PayPal pick a bad FX rate for you. Many CDMX founders run the pattern of holding a USD buffer in the LLC and only converting to pesos for actual peso expenses — keeping savings in dollars, spending in pesos. That combination — US account for revenue, SPEI for local settlement, Wise for the bridge — is the practical CDMX founder stack.

Tax: US and your home country

Treaty status: in force. The United States and Mexico have an active income tax treaty. The convention was signed in 1992, entered into force, and has applied to income tax provisions since January 1, 1994, with a later amending protocol; Mexico appears on the official IRS income tax treaties A-to-Z list and the IRS Mexico tax treaty documents page. This is one of the cleaner US treaties for cross-border operators. It caps US withholding on US-source dividends (commonly 5-10%), interest, and royalties (around 10%), and Article 7 generally protects business profits from US tax where there is no US permanent establishment. To claim treaty rates you file Form W-8BEN-E under the LLC.

For the typical CDMX consultant or agency, here is the key practical point: a single-member US LLC owned by a non-resident is, by default, a disregarded entity for US tax. If you have no US employees, no US office, and no dependent agent in the US — your work is performed from Mexico City — your service income is generally not US-source effectively connected income, so there is usually little or no US federal income tax on it. The treaty matters most for passive US-source income (dividends, interest, royalties), where it lowers or removes the default 30% withholding on FDAP income.

But there is a mandatory filing even when you owe zero US tax. A foreign-owned single-member LLC must file Form 5472 attached to a pro-forma Form 1120 every year, reporting reportable transactions between you and the LLC. Per the IRS Form 5472 instructions, the penalty for failing to file, filing late, or filing incomplete is $25,000. This is not optional and it is the single most common way non-resident founders get hurt — they form the LLC, bank happily, and never file. Mark the deadline (generally April 15, with an extension available) and treat 5472 as non-negotiable.

On the Mexican side, you remain a Mexican tax resident, so your worldwide income — including profits flowing through the disregarded LLC — is reportable to SAT on your Mexican return, and Mexico's CFC and anti-deferral rules can apply. Because the LLC is disregarded for US tax, SAT generally looks through it to you personally; the income is treated as yours and taxed under Mexican rules, with the treaty and Mexico's foreign tax credit mechanism preventing the same dollar from being taxed twice. In practice that means the reporting still happens at home even though the entity is American. A second filing to be aware of: if your LLC holds a US bank account, US information-reporting obligations such as FinCEN's BSA framework can touch the entity — and conversely, a Mexican resident with foreign financial accounts may have Mexican reporting duties as well. Confirm specifics with a Mexican contador who knows cross-border structures; this section is general information, not tax advice.

Popular use cases for Mexico City founders

The Wyoming LLC fits a handful of CDMX patterns especially well:

• Nearshore dev and engineering. Solo engineers and small studios billing US startups bill in USD into Mercury, pay themselves and any Mexican teammates via Wise-to-SPEI, and keep a clean US entity on every contract and MSA.
• Marketing, design, and content agencies. Roma and Condesa agencies running US client retainers use the LLC for Stripe US invoicing and to satisfy US clients' vendor-onboarding requirements.
• SaaS and indie products. Founders selling software to a global, USD-paying audience use the LLC to plug into Stripe, Paddle, and app-store payouts that prefer or require a US entity.
• Creators and digital products. CDMX creators earning from YouTube, Gumroad, Patreon, ad networks, and affiliate programs route US-platform payouts through the LLC's US account instead of fighting foreign-payout friction.
• Amazon and e-commerce. Sellers using Amazon US, Shopify, and US payment processors run the store under the LLC for cleaner payouts and supplier relationships.
• Cross-border consulting. Independent consultants advising US firms invoice through the LLC so the engagement looks and settles like a domestic US arrangement.

The common thread: the client or platform pays in USD, and the LLC removes the "you're a foreign vendor" friction at the exact point where money changes hands. For CDMX founders specifically, this also matters at the contracting stage — US enterprise procurement teams increasingly require vendors to have a US entity, a W-9 or W-8 on file, and a US bank account before they will even add you as an approved supplier. Without the LLC, a Mexico City studio can lose a deal not because of price or quality, but because legal and AP cannot onboard a foreign sole proprietor. With it, you clear procurement as a normal US vendor and bill on net-30 terms like everyone else.

Step-by-step from Mexico City

Mexico City runs on Central Time (UTC-6, or UTC-5 during US daylight saving), which lines up almost perfectly with US business hours and our NYC-based support window — so you are rarely waiting overnight for an answer. Dhaka-side support covers the late-night gap.

1. Submit your formation order ($397). Send your name, the desired LLC name, and your CDMX address. We confirm name availability with the Wyoming Secretary of State. Do this any time during your CDMX morning and you'll typically have confirmation the same US business day.
2. LLC is formed (~24 hours). Wyoming approves the Articles of Organization. You receive the filed formation documents and your registered agent details for year one.
3. EIN is obtained (8-10 business days). We file IRS Form SS-4 for the company. As a non-resident without an SSN, this goes by fax/mail processing, which is why it takes a couple of weeks rather than minutes. No ITIN is required to get the EIN.
4. Open your bank account (1-5 business days after EIN). With formation docs and EIN in hand, apply to Mercury first. Use your real CDMX residential address as the principal place of business and write a specific business description. If Mercury declines, move to Relay or Wise Business — we make direct introductions to all three.
5. Set up payments and FX. Connect Stripe US for client billing and open Wise Business for USD-to-MXN conversion. Link your Mexican bank so you can pull pesos via SPEI on demand.
6. File W-8BEN-E with US clients and platforms to claim Mexico-US treaty rates on any US-source passive income.
7. Calendar your annual filings. Form 5472 + pro-forma 1120 by April 15, and the Wyoming annual report on your formation anniversary. Both are cheap and routine — missing the 5472 is not.

From order to a live, billable US account, plan on roughly two to three weeks, gated mostly by EIN processing.

Common mistakes

• Skipping Form 5472. The most expensive error. Zero US tax owed does not mean zero filing. The penalty is $25,000 per the IRS. File it every year, even for a dormant LLC.
• Listing the registered agent address as your principal place of business. This is a top cause of Mercury rejections in 2025. Use your actual CDMX residential address.
• Vague bank descriptions. "Consulting" gets flagged. "Software development services for US-based SaaS startups, billed monthly" gets approved. Be concrete about what you sell and who pays you.
• Converting USD to MXN through the client's bank or PayPal. You lose 3-5% on bad FX. Hold USD in the LLC and convert through Wise at the mid-market rate only when you actually need pesos.
• Forgetting the Mexican side. The LLC does not erase your SAT obligations. You still report worldwide income at home; the treaty prevents double taxation but not double reporting.
• Choosing Delaware on autopilot. Unless you are raising VC, Delaware's franchise tax just costs you more for the same result. Wyoming is the better default for a CDMX freelancer or bootstrapped agency.
• Treating the registered agent as optional after year one. It is a legal requirement to keep the LLC in good standing. Budget the ~$100/year alongside the Wyoming annual report.

A Wyoming LLC will not change how you do the work in Mexico City — it changes how cleanly the money reaches you. For most CDMX founders billing US clients in dollars, that is exactly the upgrade worth $397.
