EOR vs Entity in Mexico: Which Model Is Right for You

Every foreign company that wants to hire in Mexico eventually faces the same decision: use an Employer of Record, or set up your own Mexican legal entity.

Both are legitimate. Both are used by serious companies. And choosing the wrong one at the wrong stage is expensive in both directions.

Set up an entity too early and you spend $10,000–$20,000 on incorporation before you have enough people to justify the overhead, then wait 8–12 weeks before your first hire.

Use an EOR for too long and you pay compounding per-employee fees while building a team that would be cheaper to operate through your own entity.

This guide gives you the complete framework: costs, compliance differences, control trade-offs, when the math flips from one to the other, and what the transition looks like.

Key takeaways

• EOR gets you hiring in 5 business days. Entity setup in Mexico takes 8–12 weeks minimum before you can run a single payroll.
  
  

• Entity setup costs $10,000–$20,000 upfront in legal and notary fees, plus $6,000–$10,000/year in ongoing compliance overhead regardless of team size.
  
  

• EOR fees run $400–$800/month per employee (flat rate) or 8–15% of gross salary depending on provider.
  
  

• The break-even in Mexico is roughly 10–15 employees, earlier than Brazil or France but later than the UK or Singapore, because Mexico's compliance overhead is non-trivial.
  
  

• EOR handles PTU distributions based on its own entity's local profits in Mexico, in strict compliance with the Federal Labor Law. 
  
  

• An entity gives you full employer brand control, direct IP ownership, and the ability to invoice Mexican clients in MXN.
  
  

• Most companies start on EOR and transition to an entity as headcount grows and the Mexico operation matures. This is an intentional path, not a failure of the initial model.
  
  

• REPSE registration is required for any EOR you use in Mexico after the 2021 outsourcing reform.
  
  

What each model actually is

Employer of Record (EOR)

An EOR is a legally established Mexican company that provides specialized services and employs the necessary talent. As a registered REPSE provider, the EOR executes the specialized work and handles all employment obligations in compliance with local labor laws.

The EOR signs the employment contracts, registers employees with IMSS, runs biweekly payroll in MXN, withholds and remits ISR, issues CFDI 4.0 payroll receipts, and handles all statutory benefits.

You work with the employees as part of your team. The EOR manages all employment obligations in Mexico.

Your company has no Mexican legal entity, no SAT registration, and no IMSS employer enrollment. You pay the EOR a service fee and a passthrough of all employment costs.

Your own Mexican legal entity

When you incorporate a Mexican legal entity (typically an S.A. de C.V. or S. de R.L. de C.V.), your company becomes the registered employer in Mexico.

You own the entity, which means you control hiring decisions, benefits structure, payroll systems, and employer brand.

You also own all compliance obligations: RFC registration with SAT, IMSS and INFONAVIT enrollment, monthly payroll filings, ISN registration, annual ISR declarations, PTU calculations, and everything else the LFT requires.

Speed comparison

This is the starkest difference between the two models.

EOR timeline

• Day 1–2: Role and compensation confirmed, employment contract drafted

• Day 2–3: Employee reviews and signs contract

• Day 3–5: IMSS registration submitted

• Day 5–14: Employee on payroll and operational

Five to fourteen business days from decision to hire, assuming complete documentation from both sides.

Entity timeline

• Weeks 1–2: Notary prepares corporate bylaws, name authorization

• Weeks 2–4: RFC registration with SAT

• Weeks 3–5: IMSS employer registration (Registro Patronal)

• Weeks 4–6: INFONAVIT and ISN enrollment

• Weeks 6–12: Mexican corporate bank account (the most unpredictable step; KYC requirements frequently delay this 4–8 weeks)

• After bank account: First payroll can run

Realistic timeline: 8–12 weeks before the first employee can be paid. Often longer if the bank account process extends, which it frequently does.

For a company that needs to hire in Mexico within weeks, entity setup simply is not on the table as a starting structure.

Cost comparison

EOR costs

EOR pricing has two components beyond the employee's gross salary: the statutory employer contributions and the EOR service fee.

Statutory employer contributions are the same regardless of whether you use an EOR or your own entity. Every employer in Mexico pays them:

Total: 30–40% above gross salary for most roles and locations, rising to 35–45% annualized when aguinaldo and PTU are included.

EOR service fee: $400–$800 USD/month per employee (flat rate models) or 8–15% of gross salary (percentage models). For a mid-level engineer earning MXN 70,000/month ($3,889 USD), the fee represents roughly 10–20% of gross salary.

Entity costs

One-time setup: $10,000–$20,000 in legal fees, notary costs, government registration fees, and professional services.

Ongoing monthly overhead (fixed regardless of team size):

This fixed overhead is the key number. It costs roughly the same to maintain a compliant Mexican entity with 3 employees as it does with 30.

That fixed cost structure is exactly what makes entity setup attractive at scale and unattractive early.

The break-even calculation

At what headcount do entity costs become cheaper than EOR fees?

Using a mid-level team at MXN 65,000/month average gross salary ($3,611 USD):

EOR fee estimated at $500/employee/month flat. Actual numbers vary by provider and salary level.

The pure math suggests break-even at 3–5 employees. But Mexico's entity compliance overhead is materially more demanding than markets like the UK or Singapore.

Many US nearshore teams with 5–8 employees stay on EOR longer than the pure math suggests.

Monthly SAT uploads, IMSS calculations, CFDI reconciliations, and annual PTU filings require a local finance hire or an external contador.

In practice, Mexico's EOR-to-entity break-even is closer to 10–15 employees for most technology and professional services companies, earlier if you have an experienced Mexico operations lead, later if you do not.

Compliance comparison

Both models make you responsible for funding statutory employment costs. What differs is who is accountable for filing, calculating, and remitting them.

One important difference: PTU under EOR is calculated on the EOR's local taxable profit, not your company's global profits.

Since EOR entities earn limited service margins, PTU obligations for your employees are often significantly lower through an EOR than through your own profitable entity.

Control and brand comparison

This is where the entity model wins clearly.

What an entity gives you that EOR cannot

• Your company name on every employment contract. Employees are employed by your company, not a third-party provider.
  
  

• Direct employer brand in the Mexican market. Important for attracting senior technical talent who research potential employers.
  
  

• Full control over benefits design. You set supplementary health insurance, equity, bonuses, and everything above the statutory floor.
  
  

• Direct invoicing in MXN. If your Mexico operation needs to invoice Mexican clients, your entity is the correct vehicle. An EOR cannot invoice your customers on your behalf.
  
  

• IP ownership clarity. Under your own entity with direct employment contracts, IP assignment is straightforward and unambiguous.
  
  

• Control over payroll systems and data. You own the payroll records, the CFDI history, and the IMSS contribution data directly.
  
  

What an EOR provides that an entity cannot

• Speed. No entity setup delivers a hired, payrolled employee in five business days.

• Flexibility. Scale up or down without entity wind-down costs. Closing a Mexican entity takes 6–12 months and involves notary procedures, SAT clearances, and IMSS de-registration.

• Lower initial capital requirement. No $10,000–$20,000 upfront cost before the first hire.

• Reduced operational burden. No need for an internal Mexico finance or HR function in the early stages.

• PE risk elimination. A properly structured EOR arrangement removes the dependent agent permanent establishment exposure that unstructured contractor arrangements create.

When each model clearly wins

Use an EOR when

• You need to hire in Mexico within weeks, not months

• Your Mexico team is fewer than 5–8 people and may still change in size

• You are testing the Mexico market before making a long-term commitment

• You have no internal operations capacity to manage Mexican corporate compliance

• Your Mexico operation is distributed and remote, with no office and no physical presence

• You want to avoid the $10,000–$20,000 upfront cost before headcount justifies it

Set up your own entity when

• Your Mexico team exceeds 10–15 employees with a multi-year commitment

• You need to invoice Mexican clients directly under your company name

• IP ownership and employer brand matter significantly for your talent strategy

• You have or are building an internal Mexico finance or HR function

• Your operation involves physical infrastructure: a facility, a warehouse, manufacturing

• You have already validated the Mexico market and are moving from testing to permanent presence

The hybrid model

Many companies use both simultaneously. A foreign parent can operate a Mexican subsidiary for core roles while maintaining EOR arrangements for sales staff or short-term project roles.

There is no legal barrier, provided roles are not duplicated or structured to evade labor obligations.

What the EOR-to-entity transition looks like

Most companies that start on EOR eventually transition employees to a directly owned entity as the Mexico operation scales. This is an intentional, planned path.

The transition typically follows this sequence:

1. Decide on entity type: S.A. de C.V. for most foreign-owned operations; S. de R.L. de C.V. for private partnerships or smaller professional services firms
   
   

2. Engage a Mexican notary and legal counsel: Draft corporate bylaws, authorize company name, complete notarial procedures
   
   

3. RFC registration with SAT: Obtain the entity's tax ID
   
   

4. IMSS employer registration: Obtain Registro Patronal before any employee can be enrolled
   
   

5. INFONAVIT and ISN enrollment: Register with housing fund and state payroll tax authorities
   
   

6. Open a Mexican corporate bank account: Allow 4–8 weeks for this step
   
   

7. Coordinate transition with EOR: For each employee, the EOR processes an IMSS baja (de-registration), and the new entity files an IMSS alta (re-registration). Employment contracts are re-issued under the new employer entity.
   
   

8. CFDI infrastructure: Set up an authorized CFDI 4.0 issuance mechanism for the new entity
   
   

Employee continuity and seniority are preserved through the transition when executed correctly with proper sustitución patronal documentation.

The question you need to answer first

Before running the cost model, answer this:

Is your Mexico strategy a commitment or a test?

If it is a test (validating whether Mexico works for your hiring needs, team culture, or product market), use an EOR.

The entire point of an EOR is to run that test with real employees and real compliance.

No $10,000–$20,000 upfront cost. No months locked into an entity you might later wind down.

If it is a commitment: you know Mexico is part of your permanent operating structure, you have the headcount to justify it, and you can manage the compliance burden.

The entity is the right structure, and the sooner you start incorporation, the sooner you stop paying EOR fees you have outgrown.

Most companies are honest: they start as a test and gradually become a commitment. Starting on EOR is not a compromise. It is the correct sequencing.

Frequently asked questions

What is the difference between an EOR and a Mexican entity?

An EOR is a legally established Mexican company that provides specialized services and employs the necessary talent. You work with the employees as part of your team. The EOR manages all employment obligations in Mexico.

Your own Mexican entity makes your company the direct legal employer, giving you full control but also full compliance responsibility.

How long does it take to set up a Mexican entity vs. using an EOR?

Entity setup takes 8–12 weeks minimum, often longer due to bank account delays. An EOR can have an employee hired, contracted, and on payroll in 5–14 business days.

At what headcount does a Mexican entity become cheaper than an EOR?

The break-even is roughly 10–15 employees for most Mexico operations. The pure cost math suggests 3–5, but Mexico's monthly compliance overhead requires internal capacity or an accountant that narrows the advantage.

Most US nearshore teams stay on EOR longer than the cost model alone would predict.

Can I use both an EOR and my own Mexican entity at the same time?

Yes. Many companies operate a Mexican subsidiary for core roles while using EOR for sales staff or short-term project roles.

There is no legal barrier provided roles are distinct and not duplicated.

What is REPSE and why does it matter for EOR in Mexico?

REPSE is Mexico's federal registry for specialized service providers, required under the 2021 outsourcing reform. An EOR without active REPSE is classified as illegal subcontracting.

Verify any EOR's REPSE number in the federal registry before signing.

Does PTU differ between EOR and my own entity?

Yes, significantly. Under EOR, PTU is calculated on the EOR entity's local taxable profit, typically a limited margin.

Under your own entity, PTU is calculated on your entity's profits. For profitable international companies, EOR often results in materially lower PTU obligations.

What happens to employees when we transition from EOR to our own entity?

The EOR processes an IMSS de-registration (baja) for each employee, and your new entity files a re-registration (alta).

Employment contracts are re-issued under your entity. Seniority and continuity are preserved through correct sustitución patronal documentation.
