Should You Register a Company First or Start Selling When Entering Mexico’s E-Commerce Market?

When entering Mexico’s e-commerce market, the first question many ask is whether to register a company in Mexico first.

The second question follows: Once the company is registered, can you immediately start selling on platforms like Mercado Libre or TikTok Shop?

The answer is: Whether to start with a company or a store depends on whether you’re opening a cross-border or local store; having a Mexican company does not automatically mean you can start selling. There are still steps like obtaining a tax ID, electronic signature, local bank account, and importer registration.

Starting in 2026, Mexico’s e-commerce rules change: platforms will withhold more VAT and income tax from sellers, Mercado Libre will verify tax IDs, and import tariffs for some Chinese goods will rise significantly. The wrong order can lead to over-withholding or even prevent you from opening a store.

This article clarifies the onboarding paths for both platforms, the sequence of company and store registration, and introduces our one-stop service for Mexican e-commerce sellers, covering company registration, tax compliance, and store setup.

Part One: Clarify the Difference – Cross-Border Stores vs. Local Stores

On both Mercado Libre and TikTok Shop in Mexico, you can choose between cross-border and local stores. Whether you need a Mexican company depends on which path you take.

1. What Entity to Use for Registration

• Cross-border store: A business license from mainland China or Hong Kong is sufficient; no Mexican company is required.

• Local store: A Mexican company (or a legally identified Mexican individual) with a Mexican tax ID (RFC).

2. How to Ship Goods

• Cross-border store: Ship directly from China, use platform overseas warehouses, or a consignment model. TikTok Shop currently requires cross-border stores to ship from Mexico’s local warehouses.

• Local store: Goods are imported under the Mexican company’s name and shipped from local warehouses, offering faster delivery and better traffic.

3. How Taxes Are Withheld

Starting 2026, Mexican e-commerce platforms must withhold VAT (IVA) and income tax (ISR) from sellers’ revenue. The withholding rate depends on whether you have an RFC and where the money is received:

Withholding does not equal final tax liability. Sellers with an RFC must file monthly and annual tax returns, receiving refunds if overpaid. Without an RFC, withheld taxes are final.

4. Who Should Choose Which?

• Cross-border store: New entrants testing products, not yet ready to establish a local entity.

• Local store: Products already validated, scaling up, or already having a factory or company in Mexico.

In short: Cross-border stores don’t require a Mexican company; to minimize taxes and operate locally, you must have a Mexican company, RFC, and a local bank account.

Part Two: Mercado Libre (Mercado Libre) – Two Onboarding Paths

Mercado Libre is the largest e-commerce platform in Latin America, with Mexico as one of its key markets. In April 2026, Mercado Libre announced new incentives for Chinese sellers in Shenzhen and introduced semi-consignment and full-consignment services.

Path One: Cross-Border Store (Global Selling)

Entity: A business registered in mainland China or Hong Kong, primarily as a corporate seller; no Mexican company is required.

Key Documents:

• Colored scan of business license (valid for more than 30 days)

• Legal representative’s ID (front and back) with mobile phone facial verification

• International email (e.g., Gmail, Outlook)

• Cross-border payment account with the same name as the business license

• Additional permits for categories like food and cosmetics

Shipping Model: Direct shipping from China, overseas warehouses, or semi-consignment and full-consignment. Different models have different onboarding thresholds, with consignment models typically requiring minimum store revenue.

Note: If a cross-border store grows significantly in Mexico, the platform may require RFC registration. Without an RFC, the highest withholding rate of 36% applies.

Path Two: Local Store (Mexican Corporate Account)

Entity: A Mexican company, registering as a corporate account under “Soy empresa” on Mercado Libre Mexico.

Key Documents:

• Company RFC and the latest tax registration certificate (CSF)

• Valid electronic signature (e.firma)

• Tax compliance opinion (Opinión de cumplimiento) must be “compliant”

• Mexican local bank account under the company’s name

• Legal representative’s information, Mexican phone number, and address

2026 New Changes: Mercado Libre now verifies RFC entity consistency. Sellers must upload the latest CSF and sign an authorization letter online via the email registered on the CSF. Failure results in a 36% withholding rate, with no refunds for previously withheld taxes.

Shipping: Can use Mercado Libre’s official warehouses (Full). Goods stored in the warehouse typically have better exposure than self-shipped items. Self-shipped orders must be scanned and picked up within 3 business days.

Part Three: TikTok Shop Mexico – Local and Cross-Border Stores

TikTok Shop launched in Mexico on February 6, 2025, and began accepting cross-border self-operated (POP) applications from Chinese entities on August 18, 2025.

Local Store

Individual Store: Mexican individuals can register using their INE (national ID), passport, or residency card, with one store per document.

Corporate Store: Mexican local businesses must provide company registration documents, company RFC, and legal representative identification.

Payout: Must use a Mexican local bank account (CLABE for businesses), settled in Mexican pesos.

Commission: 6% across all categories, with temporary commission-free policies for new sellers. Approval typically takes 2–6 business days.

Cross-Border Store (POP Self-Operated)

Entity: Business license from mainland China or Hong Kong; individual businesses and sole proprietorships are not supported.

Shipping: Must ship from a Mexican local warehouse. Direct shipping from China is currently only available for invited sellers.

Deposit: 8,000 Mexican pesos.

Tax ID: RFC is not mandatory, but without it, the platform withholds 16% VAT and 20% income tax based on sales revenue.

In short: While TikTok Shop’s cross-border stores don’t require a Mexican company, goods must first be sent to a Mexican warehouse. Decide in advance who will handle import and customs clearance.

Part Four: Does Having a Mexican Company Mean You Can Open a Store Immediately?

No. A company is just like an “ID card”; opening a local store requires a full set of tax, banking, and import procedures.

First, let’s talk about the company itself. Foreign investors often choose a joint-stock company (S.A. de C.V.) or a limited liability company (S. de R.L. de C.V.), requiring at least 2 shareholders. The process is: name approval by the Economic Department → notarized articles of incorporation → business registration → tax registration → bank account opening → foreign investment registration (RNIE), typically taking 4–12 weeks. Documents requiring authentication or translation will take longer.

After company registration, before opening a store, confirm the following:

1. Tax Identity

Prepared by: Mexican Company

• RFC is activated, and the registered business activities match e-commerce sales

• Latest tax registration certificate (CSF)

• Valid electronic signature (e.firma)

• Tax compliance opinion is “compliant”; any back taxes must be paid first

2. Payment Account

Prepared by: Mexican Company

• Mexican bank account (CLABE) under the company’s name

• This is often the slowest step for foreign companies, as banks review shareholders, legal representatives, and sources of funds

3. Import Qualification

Prepared by: Mexican Company + Customs Broker

• To import goods under the company’s name, register as an importer (Padrón de Importadores) with SAT

• Prerequisites: RFC is valid, e.firma is active, tax address is verifiable, tax email is activated, and a customs broker is appointed

4. Products and Brands

Prepared by: Seller

• Products must meet Mexican official standards (NOM) for Spanish-language labels, depending on the category

• Register Mexican trademarks in advance to avoid being preempted or reported after listing

Note on Tariffs: Starting January 1, 2026, Mexico will impose 5%–50% import tariffs on 1,463 tax-code products from countries without free trade agreements, including China. Clothing, footwear, and home goods face up to 35% tariffs, while toys and stationery face around 30%. Calculate landed costs before pricing.

Part Five: Should You Register a Company First or Open a Store? Two Questions to Decide

If you don’t yet have a company or verified products in Mexico, start with a cross-border store. If you already have a company or validated products, go the local route.

1. Do you already have a company or factory in Mexico? If yes, complete the store qualifications (RFC, e.firma, local bank account, importer registration) and open a local store on Mercado Libre or TikTok Shop, with approximately 10.5% withholding.

2. If not, check if your product is validated in Mexico: If validated, register a Mexican company (name approval, notarization, registration, ~4–12 weeks), complete the qualifications, and open a local store; if not validated, start with a cross-border store to test the market, using a Chinese or Hong Kong company, then reassess after validation.

Regardless of the path, submit a Mexican trademark application before opening a store.

Cross-border stores have lower barriers and faster setup, ideal for product testing; local stores offer lower tax withholding, faster delivery, and better traffic, suitable for scaling.

Sellers planning to transition to local stores should start company registration while running cross-border stores. Company registration, bank account opening, and importer registration typically take months—don’t wait until the last minute.

Part Six: Six Common Pitfalls

Pitfall One: Assuming Company Registration Means You Can Open a Store

If bank account opening, e.firma, or tax compliance opinions are incomplete, you won’t be able to open a store.

Recommendation: Plan tax, banking, and importer registration simultaneously during company registration.

Pitfall Two: No RFC or Failed RFC Verification

Sellers without an RFC face 16% VAT + 20% income tax withholding (total 36%). Mercado Libre’s 2026 RFC verification failures result in no refunds for previously withheld taxes.

Pitfall Three: Local Stores Using Overseas Accounts

Even with an RFC, using overseas accounts increases VAT withholding from 8% to 16%.

Pitfall Four: Borrowing Someone Else’s Mexican Entity

Stores, funds, and tax IDs not under your name risk platform verification issues. The bigger the business, the higher the risk.

Pitfall Five: Pricing Without Calculating Tariffs

Starting 2026, import tariffs for many products will rise significantly. Pricing based on old costs means higher losses as sales grow.

Pitfall Six: Product Goes Viral, But Trademark Isn’t Registered

Mexican trademarks follow a “first-to-file” principle. If your brand is preempted, you may face takedown complaints.

Recommendation: Submit a Mexican trademark application before opening a store.

Conclusion

When entering Mexico’s e-commerce market, the sequence depends on three key factors:

1. Cross-border stores don’t require a Mexican company; you can start with a Chinese or Hong Kong entity.

2. For local stores, a company is just the first step; RFC, e.firma, and a local bank account are all essential.

3. Regardless of store type, register your trademark first.

Any missed step can lead to over-withholding or store launch delays.
