A Cheaper Way to Run Payroll in Mexico Without an EOR

Are you looking for a cheaper way to run payroll in Mexico without an employer of record (EOR)? Here's how a local entity, payroll software, and outsourced providers compare — plus the costs and rules to know.

If you're planning to hire in Mexico, an employer of record (EOR) is usually the first option that comes up. It's quick and easy, with no need to set up a local entity. But the monthly fee per employee is high, and it only grows as your team does.

The good news is that there are other ways to pay people in Mexico legally. They take more setup, but often cost less once you have a handful of employees. This guide walks through the options, what Mexican payroll involves, and how to decide which route fits your team.

Why Companies Look Beyond an EOR

An EOR becomes the legal employer of your employees in Mexico. It takes care of employment documents, payroll, taxes, and social security, plus a service fee. That fee is often a few hundred US dollars per employee each month, and it keeps going for as long as the person is on the platform.

For one or two hires, that can make sense. For five, ten, or twenty employees, the cost adds up fast. You're paying a recurring fee for work that a local setup could do at a lower cost per head.

There's another reason too. With an EOR, you don't own the employment relationship directly. Some companies want more control over benefits, contracts, and how the team is managed.

What Running Payroll in Mexico Involves

Before comparing options, it helps to know what has to happen each pay period. Mexican payroll is far more complex than a simple salary transfer.

• Income tax withholding (ISR): The employer withholds income tax and pays it to the tax authority (SAT).

• Social security (IMSS): Both employer and employee contribute, with the larger share coming from the employer. It covers health insurance, disability, retirement, and other benefits.

• Housing fund (INFONAVIT) and retirement savings (SAR): Employers pay these on top of IMSS contributions.

• State payroll tax: Nearly all Mexican states levy one, usually around 2% to 3% of payroll, though rates vary by state.

• Digital payroll receipts (CFDI): Every payment needs an official electronic receipt issued through SAT-approved channels.

• Mandatory benefits: These include the year-end bonus (aguinaldo, at least 15 days of pay, due before December 20), paid vacation with a 25% vacation premium, and profit sharing (PTU), generally 10% of taxable profits for eligible companies.

None of this is impossible to manage. But it does mean you need either local expertise or software that knows the rules.

Option 1: Set Up Your Own Mexican Entity

To employ people directly, your company needs a legal entity in Mexico. The most common types are the S. de R.L. de C.V. (similar to an LLC) and the S.A. de C.V. (a corporation).

What you'll need to do:

1. Form the entity with a notary and register it.

2. Get a tax ID (RFC) and an electronic signature (e.firma).

3. Register as an employer with IMSS, INFONAVIT, and the state tax office.

4. Open a local bank account.

5. Set up payroll and accounting.

Pros: Lower ongoing cost per employee, full control over contracts and benefits, and a clear local presence if you plan to grow.

Cons: Upfront legal and accounting costs, a setup period that often takes several weeks, and ongoing compliance work like monthly tax filings and annual reports.

This route tends to pay off when you expect to keep a team in Mexico for the long term.

Option 2: Use Payroll Software Built for Mexico

Once you have an entity, the next question is how to run payroll. Doing it by hand in spreadsheets is risky, because small errors in tax or social security calculations can lead to penalties.

Payroll software automates the calculations, generates the CFDI receipts, and keeps track of deductions and contributions. Some tools also handle direct deposits and produce the reports your accountant needs. Platforms such as Runa HR are built for this kind of local payroll work, which lets a small team run payroll without hiring a full in-house specialist.

When comparing any software, check a few things:

• Does it calculate ISR, IMSS, INFONAVIT, and state payroll tax correctly?

• Does it issue CFDI payroll receipts automatically?

• Can it handle aguinaldo, vacation premium, and PTU?

• Does it support local bank payments?

• Is support available in a time zone and language that works for you?

Software pricing is usually per employee per month too, but it's typically much lower than an EOR fee, because you're only paying for the payroll tool, not for legal employment.

Option 3: Outsource Payroll to a Local Accounting Firm

If you want your own entity but don't want to run payroll in-house, a local accounting or payroll firm can handle it for you. They manage calculations, filings, and receipts, and they usually advise on labor law as well.

This works well for companies that prefer a human point of contact and don't mind a monthly service fee. Costs vary by firm and team size, so it's worth getting two or three quotes.

One note here: Mexico restricted staff outsourcing in 2021. Providers can't simply lease you employees. They can only offer specialized services, and they must be registered in the REPSE registry. Payroll processing support is fine, but check that any provider is clear about what they do and what they're registered for.

Option 4: Independent Contractors (Use With Care)

Some companies pay Mexican workers as contractors to avoid payroll entirely. It's cheaper on paper, but it's also the riskiest route. If someone works under your direction, on a set schedule, and mainly for you, Mexican authorities can treat them as an employee. That can mean back payments for social security, taxes, and benefits, plus fines.

Contractors make sense for project-based work with independent professionals. They're not a safe replacement for regular employees.

How the Costs Compare

Exact numbers depend on your team size, salaries, and the providers you pick, so treat this as a rough guide rather than a quote.

• EOR: Low setup effort; highest ongoing cost per employee; best for very small teams (fewer than five people) or testing the market.

• Local entity plus payroll software: Medium-to-high setup effort; lower cost per employee; best for growing teams with a long-term plan.

• Local entity plus an accounting firm: Medium-to-high setup effort; moderate ongoing cost; best for teams that want hands-off payroll.

• Contractors: Low setup effort and low cost, but high legal risk; best for genuine freelance work.

A simple way to estimate your break-even point: add up the entity setup and yearly compliance costs, then divide by the monthly savings per employee compared with the EOR fee. That tells you roughly how many months it takes for your own setup to pay for itself.

Tips for Keeping Payroll Costs Down

• Start with an EOR, then switch: Many companies use an EOR for the first few hires and move to their own entity once the team grows. Ask any EOR about notice periods and transfer terms first.

• Keep records clean: Contracts, receipts, and attendance records matter in Mexican labor disputes.

• Budget for the full employer cost: Salary is only part of it. Social security, payroll tax, and mandatory benefits can add a meaningful percentage on top.

• Review yearly: Rules and rates change, including minimum wage and vacation entitlements, so check your setup at least once a year.

Final Thoughts

An EOR is a fast way to get started in Mexico, but it's rarely the cheapest option over the long run. If you plan to build a team there, setting up a local entity and pairing it with local payroll software or a trusted local provider can lower your cost per employee while giving you more control.

The right choice depends on how many people you're hiring, how long you plan to stay, and how much admin work you're comfortable handling. Whichever path you pick, talk to a local labor and tax professional before you finalize it. Mexican payroll rules are specific, and getting them right from the start is much cheaper than fixing them later.
