Cheaper way to run payroll in Mexico without EOR

Comparing the cost of an EOR vs. running payroll in Mexico yourself? Here is a side-by-side look, a cost checklist, and a simple break-even method.

The cost of an employee of record (EOR) is easy to see. It’s a line on an invoice. The cost of running payroll yourself is harder to see, because it’s spread across legal fees, software, and accounting. That’s why many teams never do the comparison.

This article puts both sides in one place, so you can compare them and work out where the more cost-effective option actually is.

Payroll options compared

There are two ways to pay employees in Mexico: through an EOR or through your own local entity using a payroll system. Each one answers the same question differently: who is the legal employer, and who does the monthly work?

How much does an EOR cost in Mexico?

One published guide puts typical EOR fees in Mexico at roughly 400 to 600 USD per employee per month. Your quote may differ. The EOR route has one main cost and a few smaller ones:

• The monthly fee per employee. This is the main cost, and it repeats for every person.
• Pass-through employer costs. Social Security, payroll tax, and mandatory benefits still get billed to you.
• Possible extras. Benefits above the legal minimum, onboarding fees, or termination handling can cost more.
• Exit terms. Some contracts set notice periods or transfer fees if you move employees elsewhere.

How much does it cost to run payroll in Mexico yourself?

With your own entity, the costs split into one-time and recurring.

One-time:

• Notary and legal fees to form the company
• Tax ID (RFC) and electronic signature (e.firma)
• Employer registrations with IMSS, INFONAVIT, and the state
• Opening a business bank account

Recurring:

• Accounting and yearly tax filings, which apply even if the company is small
• Payroll software or an outsourced payroll service
• The same employer costs you’d pay under an EOR (social security, payroll tax, benefits)
• Possibly a registered address or local legal representative

The employer costs appear on both sides of the comparison. They aren’t a reason to pick one route over the other. The real difference is the EOR fee on one side versus the entity, software, and accounting on the other.

What payroll system do you need for Mexico?

Payroll software is usually the smallest recurring cost on the “own entity” side, and it’s the one that prevents the most mistakes. Mexican payroll needs income tax withholding, IMSS contributions based on each person’s integrated salary, state tax, and a CFDI receipt for every payment.

Platforms such as Runa HR are designed around these local rules, which helps a small team avoid doing the math in spreadsheets. When you price tools, compare what’s included: CFDI receipts, tax table updates, bank payments, year-end items like the aguinaldo, and what support looks like when a number seems wrong.

Using a platform like Runa HR can also help streamline recurring payroll administration, giving internal teams more time to focus on business operations rather than manual calculations and paperwork.

How do you work out when going without an EOR pays off?

You don’t need a complicated model. You need four numbers from real quotes:

1. A: One-time costs of setting up your own entity
2. B: Monthly cost of your own setup (software + accountant + filings)
3. C: Monthly EOR fees for your current or planned team
4. Months to break even = A ÷ (C − B)

If C is smaller than B, an EOR is cheaper for your team size today, and that’s a fine answer. If C is larger, the result tells you how many months until the entity pays for itself. Then ask yourself whether you plan to keep a team in Mexico that long.

Run the formula twice: once with your current headcount, and once with the headcount you expect in 12 to 24 months. The second result often looks very different.

Costs people often forget to include

• Time: Someone on your team will spend hours each month reviewing payroll, even with good software.
• Mistakes: Late or wrong filings can lead to penalties. Budget a small cushion for review by a professional.
• Switching costs: Moving employees from an EOR to your own entity needs legal care so seniority and accrued benefits carry over.
• Bonus months: The year-end bonus (at least 15 days of salary, due before December 20) and profit sharing can create cash flow spikes.

Questions to ask before you decide

• How many people will we employ in Mexico in the next two years?
• Do we have someone who can own payroll each month, or will we outsource it?
• What do the EOR contract’s notice and exit terms say?
• Have we gotten at least two quotes for entity setup and for accounting?

Final thoughts

The cheaper way to run payroll in Mexico depends on how long you’ll stay and how big the team will get. Put your real quotes into the break-even formula, and the answer usually becomes clear. For businesses choosing to manage payroll independently, a local payroll solution like Runa HR can make the process more manageable while helping teams handle Mexico’s payroll requirements.

Before committing, have a local tax and labor professional review the plan. Rules and rates change, and a short review costs far less than fixing a mistake later.
