Why Mexican FBA sellers choose a Delaware LLC

A Mexican entrepreneur selling on Amazon already lives inside one of the few markets that shares a land border, a trade agreement, and a deeply integrated supply chain with the United States. That proximity is an advantage, but it does not automatically give a Mexico City seller a clean way to receive Amazon US disbursements, hold US dollars, or present a US business identity to American suppliers and prep centers. A Delaware LLC closes that gap. It gives the seller a recognized US legal entity, an Employer Identification Number, and the ability to open a US-based business account that Amazon treats as a domestic deposit destination rather than a foreign one.

The appeal is practical rather than symbolic. Amazon Seller Central asks for a legal entity name, a tax identification number, and a deposit method during registration and again whenever the account is reviewed. A founder operating only as a Mexican persona fisica can technically sell, but the dollar economics, the supplier credit terms, and the banking friction usually push a serious seller toward a US structure within the first year. A Delaware LLC is the structure most non-US sellers reach for because Delaware processes formations quickly and the single-member LLC is treated as a pass-through that the seller reports at home.

It helps to separate the legal entity from the tax question early. Forming the LLC is a state filing. How Amazon income is taxed, where it is taxed, and what forms get filed are separate matters governed by US federal rules and by Mexican law. The sections below walk through each layer so a seller in Guadalajara, Monterrey, or Mexico City can see the whole picture before paying a single fee.

The realistic banking approval picture for Mexican founders

Banking is the part most Mexican sellers underestimate. The good news is that Mexico sits in a favorable tier for US fintech account approval. Wise and Payoneer open accounts for Mexican-resident owners of US LLCs reliably, and both integrate cleanly with Amazon disbursements in US dollars. Payoneer in particular has long been a default for Amazon sellers because Amazon recognizes it as a supported receiving method in most marketplaces. These two should be treated as the dependable base layer rather than a fallback.

Mercury sits a step higher in usefulness because it offers a genuine US business checking account with routing and account numbers, virtual cards, and cleaner integration with US suppliers and software. For a Mexican applicant, Mercury approval is realistic but not guaranteed. It reviews the LLC formation documents, the EIN letter, the owner's passport, and the stated business activity. A clear description of an Amazon FBA business with a real product line and a residential or business address in Mexico improves the odds. Relay and Lili are additional US banking options worth holding in reserve if the first application stalls.

The practical sequence matters. Do not apply to any bank before the LLC is formed and the EIN has arrived, because every provider asks for both. Apply to Wise or Payoneer first so disbursements have a home, then apply to Mercury once you can attach the EIN confirmation letter. If Mercury declines, it is rarely a permanent rejection and often reflects a thin application rather than the applicant's country. Reapplying with a complete profile and an active sales history usually changes the result.

How an Amazon FBA business actually earns

Understanding the revenue mechanics clarifies everything downstream, including banking and tax. An FBA seller buys or manufactures inventory, ships it into Amazon's US fulfillment network, and lets Amazon handle storage, picking, packing, shipping, and returns. The seller's money comes from the spread between the landed cost of a unit and the price a US customer pays, minus Amazon's referral fee, the FBA fulfillment fee, storage charges, and advertising spend. For a Mexican seller, the landed cost often includes cross-border freight and customs handling, which makes margin discipline more important than for a domestic US competitor.

Amazon does not pay the seller in real time. It settles on a disbursement cycle, typically every two weeks, after holding a reserve against returns and chargebacks. Those disbursements land in whatever bank account the seller has attached, which is why the US banking layer is not optional for a Mexican founder who wants dollars rather than a forced peso conversion at an unfavorable rate. The disbursement is gross of nothing the seller still owes Amazon, so reconciling settlement reports against bank deposits is part of the monthly routine.

Because inventory is the engine, cash gets tied up in stock that sits in Amazon warehouses for weeks before it sells. A Mexican seller financing inventory from peso income feels currency risk on every restock. This is one more reason the US dollar account is structural rather than cosmetic. It lets the seller hold revenue in the same currency the inventory and fees are denominated in, which removes a layer of exchange volatility from the unit economics.

How Amazon FBA income is taxed for a Mexican-owned LLC

A single-member Delaware LLC owned by a Mexican resident is, by default, a disregarded entity for US federal tax purposes. That means the LLC itself does not pay US income tax as a separate taxpayer. The question becomes whether the income is effectively connected to a US trade or business and whether the foreign owner has a US tax filing obligation on it. For many service businesses run entirely from abroad, the answer leans toward no US tax. FBA is more nuanced because the seller holds inventory inside the United States and uses US fulfillment infrastructure, which can create a stronger US nexus argument than a pure remote service would.

This is exactly where a qualified US tax adviser earns the fee. The analysis turns on facts such as whether the seller has dependent agents in the US, how title to goods passes, and how the activity maps onto the permanent establishment concept. A Mexican seller should not assume either extreme. Some FBA structures generate a US filing and possible US tax on effectively connected income, while others, with careful structuring, do not. Guessing in either direction is the costliest mistake in this whole profile.

Whatever the US conclusion, the Mexican side remains. As a Mexican tax resident, the founder generally reports worldwide income to the SAT, and income flowing through a disregarded US LLC is generally reported at home. The job of the tax adviser is to position the two systems so the same dollar is not taxed twice without relief and so each return is consistent with the other. The treaty framework that already coordinates the two authorities is the backdrop for that work, but the seller still needs a professional to apply it to FBA facts.

The Form 5472 duty you cannot skip

Even when a Mexican-owned single-member LLC owes no US income tax, it almost always owes a US information filing. A foreign-owned disregarded LLC must file Form 5472 attached to a pro forma Form 1120 every year to report reportable transactions between the LLC and its foreign owner. Reportable transactions include capital the owner contributes to fund inventory, money the LLC distributes back to the owner, and amounts the owner pays on the LLC's behalf. For an FBA seller funding stock from Mexico and pulling disbursements back home, these transactions happen constantly, so the form is rarely empty.

The penalty for getting this wrong is severe and is the single most important number in this article. Failing to file Form 5472, or filing it late or incomplete, carries a $25,000 penalty per form per year. This is not income tax, so it applies regardless of whether the business was profitable. A seller who forms an LLC, sells for a year, and never files has exposure to that penalty even with modest revenue. The cost of preparing the form correctly is trivial against that figure, which is why no FBA seller should treat it as optional.

The mechanics are manageable with help. The pro forma 1120 carries only identifying information rather than a full corporate tax computation, and the 5472 reports the transaction categories and amounts. The filing is due on the regular corporate deadline and must be filed even for a year with little activity. A seller should keep clean records of every contribution and distribution throughout the year so the form can be completed accurately rather than reconstructed under deadline pressure.

BOI reporting and what changed for US-formed LLCs

Beneficial ownership reporting under the Corporate Transparency Act caused real anxiety for non-US founders when it first took effect, because it looked like a new annual disclosure of personal ownership details to a US financial agency. For a Mexican seller weighing a Delaware LLC, that obligation felt like a meaningful downside. The rules have since shifted in a way that removes the concern for this exact profile.

Under the FinCEN Interim Final Rule issued on March 26 2025, US-formed entities are exempt from the beneficial ownership information reporting requirement. A Delaware LLC formed by a Mexican founder is a US-formed entity, so it falls inside that exemption and does not file the BOI report that earlier guidance contemplated. This is a genuine simplification for the FBA seller, who can form the entity without adding a recurring federal ownership disclosure to the calendar.

Two caveats keep this honest. First, the exemption applies to the federal BOI filing and does not touch the separate Form 5472 obligation described above, which remains fully in force. Second, rules in this area have moved more than once, so a seller forming an entity in a later year should confirm the current state of the requirement with their adviser rather than assuming the March 2025 position is permanent. For a formation under the rule as it stands, the BOI report is not part of the workload.

The formation timeline from the Central Time Zone

Mexico City runs on Central Time, which overlaps heavily with US business hours, and that overlap quietly removes friction from the whole process. Filing offices, registered agents, banks, and Amazon support all operate on schedules a Mexico City founder can reach without working through the night. A seller in Monterrey or Guadalajara sits in the same or an adjacent zone, so the practical experience is similar across the country. This is a small advantage over founders in Asian or European time zones who handle US providers at awkward hours.

The formation itself is a state filing in Delaware. The Certificate of Formation is filed with the Delaware Division of Corporations, and the standard processing window for the rest of the setup runs about a week and a half once everything is in motion. The EIN is the part that adds calendar time for a non-US founder, because without a US Social Security Number the application goes in on Form SS-4 and is processed manually, which typically takes around eight to ten business days to come back. Planning around that window prevents a stalled bank application.

Because the EIN gates the banking step, the realistic end-to-end timeline is driven by that government processing rather than by the Delaware filing. A founder who files the entity, requests the EIN immediately, and prepares bank applications in parallel can be fully operational within a few weeks. The time zone alignment helps here too, because any back and forth with the registered agent or the bank resolves inside the same working day rather than bouncing across an overnight gap.

Currency, peso exposure, and moving money home

An FBA business denominated in US dollars but funded and ultimately enjoyed in pesos lives with constant currency exposure. Inventory cost, Amazon fees, advertising, and revenue are all in dollars, while the founder's living expenses and often the working capital are in pesos. The peso is a relatively liquid and freely traded currency, which makes conversion straightforward, but the rate moves enough that timing matters on large transfers such as a restock or a profit repatriation.

Holding revenue in a US dollar account through Wise, Payoneer, or Mercury lets the seller keep dollars as dollars until conversion is actually needed. That single habit reduces the number of round trips through the exchange rate. When the seller does move money to Mexico, the multi-currency fintech accounts generally offer transparent conversion at rates close to the mid-market figure, which beats a forced conversion baked into a traditional wire. Comparing the effective rate before each large transfer is worth the minute it takes.

Repatriation from the LLC to the Mexican owner is a distribution, and for a disregarded entity it is a movement of the owner's own money rather than a dividend from a separate taxpayer. That distribution is one of the reportable transactions captured on Form 5472, so it needs to be logged. On the Mexican side, the income generally enters the founder's worldwide reporting regardless of when the cash physically arrives. Keeping the dollar account, the peso account, and the bookkeeping reconciled monthly keeps both the US filing and the SAT return defensible.

USMCA, cross-border inventory, and customs realities

Mexico's place inside the North American trade framework shapes how an FBA seller sources and ships. A founder who manufactures or buys in Mexico and sells into Amazon US is moving physical goods across the border, and the trade agreement that governs that corridor can affect duty treatment depending on the product and its origin. This is a real operational factor that a seller in, for example, Brazil or Pakistan does not have in the same form, because Mexico's goods cross a single land border into the destination market.

Practically, that means a Mexican FBA seller has to think about customs classification, country of origin, and import documentation as part of the cost of goods, not as an afterthought. Goods entering the US for sale through Amazon are imports, and the seller or their freight partner acts as the importer with the obligations that role carries. Getting the classification and origin paperwork right protects the landed cost assumptions the whole margin depends on. A customs broker is usually worth engaging before the first large shipment.

The Delaware LLC does not change customs law, but it can become the importing entity of record, which keeps the US business identity consistent across Amazon, banking, and the border. Pairing the US entity with a Mexican manufacturing or sourcing arrangement is a common shape for this profile. The seller should treat the trade and customs layer as a distinct workstream with its own advisers, separate from the formation and tax work, because the rules and the paperwork are genuinely different.

Common mistakes for the Mexico plus FBA profile

The most expensive mistake is ignoring Form 5472. Sellers see that a disregarded LLC may owe no US income tax and wrongly conclude there is nothing to file. The information return is separate from income tax and carries the $25,000 per form penalty, and the contributions and distributions an FBA seller makes are precisely the reportable transactions the form exists to capture. Treating the LLC as a fire-and-forget entity is how a profitable small business ends up with a penalty larger than a year of margin.

The second common error is opening a bank account before the EIN exists, or applying to Mercury with a thin profile and treating the decline as final. Every provider wants the formation documents and the EIN letter, so the order of operations is fixed. A Mexican seller who applies to Wise and Payoneer first, then approaches Mercury with a complete application and some sales history, avoids the stalled-setup trap that frustrates founders who rush the sequence.

A third mistake is conflating the US tax question with the Mexican one and handling neither well. Some sellers assume a US LLC makes them invisible to the SAT, and others assume the Mexican entity makes the US filings unnecessary. Both assumptions are wrong. As a Mexican resident the founder generally reports worldwide income at home, and the US entity carries its own information filings and a possible effectively connected income analysis. Engaging one adviser who can see both systems, or a coordinated pair, prevents the seller from optimizing one return into a problem on the other.

What the formation actually costs

Cost predictability matters when a seller is also financing inventory, so it helps to lay out the real numbers. The Delaware Certificate of Formation carries a $110 state filing fee. Delaware then charges a flat $300 annual franchise tax on LLCs, due each year on June 1, which is a fixed figure rather than a percentage of income or assets. That flat structure is part of why Delaware is straightforward for small foreign-owned entities, because the seller can budget the same number every year regardless of sales volume.

The EIN is free. The application is submitted on Form SS-4, and a non-US founder without a Social Security Number files it through the manual process that takes roughly eight to ten business days to return the confirmation letter. Anyone charging a large standalone fee purely to obtain the EIN is charging for a government service that costs nothing, so the seller should understand that the value in a paid service is the handling and the accuracy, not the number itself.

Against those government figures, the formation service is offered at $297 as one-time pricing. That covers the setup work that gets a foreign founder from nothing to a filed entity with an EIN request in motion. The seller should still budget separately for the recurring $300 franchise tax, for the annual Form 5472 preparation, and for the US and Mexican tax advice the FBA structure warrants. Knowing which costs are one-time and which recur prevents an unpleasant surprise the following June.

A practical step-by-step for a Mexican FBA seller

Start by confirming the business shape before filing anything. Decide that a single-member Delaware LLC fits, gather the passport, settle on the legal name and the Mexican address you will use, and write a one-paragraph description of the FBA business that you can reuse on every bank and Amazon form. Doing this groundwork first means the rest of the process is data entry rather than decision making, which is what keeps a setup inside the few-week window rather than dragging across months.

File the Certificate of Formation with the $110 fee, then request the EIN on Form SS-4 the same week so the eight to ten business day clock starts immediately. While the EIN is processing, prepare the Wise and Payoneer applications so they can go in the moment the confirmation letter arrives, and assemble the documents Mercury will want. Keep the time zone advantage in mind and handle each provider during overlapping business hours so any clarification resolves the same day.

Once banking is live, connect a US dollar account to Amazon as the disbursement method, engage a US tax adviser to settle the effectively connected income question and to calendar the annual Form 5472 with its $25,000 penalty firmly in view, and line up Mexican advice so your SAT reporting stays consistent with the US side. Diarize the $300 franchise tax for June 1 each year, log every contribution and distribution as you go, and confirm that the BOI exemption for US-formed entities under the March 26 2025 Interim Final Rule still stands at the time you file. That sequence takes a Mexico City seller from idea to a compliant, dollar-banked FBA operation without the gaps that create penalties later.
