What Is INFONAVIT in Mexico? Employer's Guide (2026)

If you are hiring in Mexico, INFONAVIT is one of the first terms you will encounter.

It appears on every payroll calculation, every employer cost model, and every employment contract. It is not optional, and it is not small.

This guide explains exactly what INFONAVIT is, how it works, what employers must contribute, how the calculation is done, and what happens when it is not handled correctly.

Key takeaways

• INFONAVIT is Mexico's national housing fund. Every registered employer must contribute 5% of each employee's integrated daily salary on every payroll cycle.
  
  

• The contribution is entirely employer-paid. Employees do not pay INFONAVIT out of pocket. It is an employer obligation added on top of gross salary.
  
  

• INFONAVIT contributions are tied to the Salario Base de Cotización (SBC), not just gross salary. Mismodeling the SBC is the most common INFONAVIT budgeting error.
  
  

• Contributions are remitted bimonthly (every two months) through the SUA system, by the 17th of the month following each bimonthly period.
  
  

• Employees use INFONAVIT credits to buy homes or receive the balance as a retirement supplement if they never take a housing loan.
  
  

• Non-payment triggers immediate penalties: surcharges, fines, and IMSS audit risk.
  
  

• Foreign companies without a Mexican entity cannot manage INFONAVIT directly. An Employer of Record handles all INFONAVIT obligations on your behalf.
  
  

What INFONAVIT stands for and what it does

INFONAVIT stands for Instituto del Fondo Nacional de la Vivienda para los Trabajadores, which translates to the National Institute of the Housing Fund for Mexican Employees.

It is a federal institution created in 1972 under Mexico's Federal Labor Law (LFT) and operated jointly by employer, employee, and government representatives.

Its primary function: ensure every Mexican employee has access to housing.

It does this through two mechanisms:

1. Housing loans (créditos hipotecarios): Employees with sufficient contribution history can apply for an INFONAVIT-backed mortgage to buy a home

2. Retirement supplement: Employees who never use their housing credit receive the accumulated balance added to their retirement savings when they reach pension age

INFONAVIT is not a tax. It is a mandatory employer contribution to an individual housing savings account registered in each employee's name. The money belongs to the employee. The employer is the contributor.

Who must contribute to INFONAVIT

Every employer with at least one registered employee in Mexico must make INFONAVIT contributions.

There are no exemptions based on:

• Company size (one employee or one thousand, same obligation)

• Company nationality (Mexican-owned or foreign-owned EOR clients alike)

• Employment type (permanent or temporary contracts both qualify)

• Remote or on-site status (work location does not affect the obligation)

The only exception: employees in certain government regimes covered under different pension law, which does not apply to private sector employers.

If your company uses an Employer of Record in Mexico to hire locally, the EOR registers with INFONAVIT and remits contributions on your behalf. Your company has no direct INFONAVIT registration requirement.

How INFONAVIT contributions are calculated

The calculation has three inputs:

1. The Salario Base de Cotización (SBC): The integrated daily salary used as the contribution base

2. The contribution rate: Fixed at 5% for all employers

3. The bimonthly period: Contributions cover two-month blocks

What is the Salario Base de Cotización (SBC)?

The SBC is not simply the employee's gross monthly salary divided by 30.

It is the integrated daily rate that includes:

• Base daily salary

• Prorated aguinaldo (Christmas bonus)

• Prorated vacation premium

• Any other regular payments: food vouchers, transport allowances, bonuses paid periodically

The SBC formula:

SBC = Daily base salary × Integration factor

The integration factor for a new employee in year one is approximately 1.0493, reflecting the prorated value of aguinaldo and vacation premium.

It increases slightly as the employee's vacation entitlement grows with seniority.

For a full breakdown of how the SBC is built and updated, the SBC recalculation process in Mexico covers every step with worked examples.

Contribution calculation example

So for an employee earning MXN 60,000/month gross, the employer remits approximately MXN 6,271 to INFONAVIT every two months, or roughly MXN 3,136 per month when budgeted monthly.

Exchange rate for USD reference: MXN 18 per USD (2026 Banxico reference rate).

The SBC cap

INFONAVIT contributions are capped at 25 UMA units per day. The UMA (Unidad de Medida y Actualización) is Mexico's annual indexing unit.

For 2026, the daily UMA is MXN 1

08.57, making the daily SBC cap MXN 2,932.75.

For high-salary employees whose SBC exceeds this cap, INFONAVIT contributions are calculated on the capped amount, not the full integrated salary.

To understand how UMA functions across labor law calculations, the UMA in Mexico explained article covers its full scope.

When are INFONAVIT contributions due?

INFONAVIT contributions are remitted bimonthly (every two months), not monthly.

The bimonthly periods and their payment deadlines:

Payments are made through the SUA system (Sistema Único de Autodeterminación), the unified platform where IMSS and INFONAVIT contributions are filed together.

Note that while IMSS employer contributions are also due by the 17th, IMSS runs on a monthly cycle. INFONAVIT runs bimonthly. Both are processed through SUA, but the frequency differs.

INFONAVIT vs. IMSS: understanding the difference

Both are mandatory employer contributions. Both are calculated on the SBC. But they serve different purposes and have different structures.

For a full breakdown of how IMSS contributions are structured alongside INFONAVIT, the IMSS employer and employee contribution structure explains both systems side by side.

Both obligations together, along with AFORE retirement contributions, form the core of Mexico's mandatory social security system that every employer must participate in from the first day of employment.

What employees do with their INFONAVIT balance

Every employee in Mexico has an individual INFONAVIT sub-account registered under their NSS (Número de Seguridad Social).

Each bimonthly contribution from the employer goes into this account. The employee can:

Use it as a mortgage

Once an employee accumulates enough contribution points (based on salary level, age, and years of contributions), they qualify for an INFONAVIT housing loan.

INFONAVIT offers three main credit types:

• Crédito INFONAVIT: Direct INFONAVIT mortgage for purchasing a home

• Cofinavit: Combined INFONAVIT credit and bank financing for higher-value properties

• Mejoravit: Smaller credits for home renovation and improvements

The employee applies independently. The employer's obligation is simply to keep contributions current. An employee with a gap in contributions cannot apply for a housing loan during that period.

Receive it at retirement

Employees who never use their INFONAVIT housing credit receive the accumulated balance as a retirement supplement when they reach pension age through IMSS.

The balance is deposited into their individual AFORE (retirement savings) account at that time.

INFONAVIT and the employer's broader cost picture

INFONAVIT is one of several mandatory contributions that push the true cost of employment significantly above gross salary.

When you add all statutory obligations together, the total cost of hiring an employee in Mexico runs 30–40% above gross salary for most roles and locations.

Here is how INFONAVIT fits into the full employer cost stack:

INFONAVIT alone adds a meaningful monthly line item. For an employee earning MXN 60,000/month, it represents approximately MXN 3,136/month in employer cost on top of gross salary.

For a complete picture of every mandatory benefit that sits alongside INFONAVIT, the mandatory benefits in Mexico guide covers all obligations in one place.

What happens if employers miss INFONAVIT payments

Non-payment or late payment of INFONAVIT contributions triggers automatic penalties. These are not discretionary. They apply from the first day a payment is overdue.

Surcharges (recargos)

Late payments accrue monthly surcharges at a rate set by Mexico's fiscal code.

In 2026, the standard monthly surcharge is 1.47% of the unpaid amount, applied from the first day past the deadline.

Fines (multas)

INFONAVIT can levy fines for non-payment. Penalty amounts depend on the number of days overdue and the size of the obligation.

IMSS audit exposure

Because IMSS and INFONAVIT share the SUA filing system, an INFONAVIT discrepancy often triggers a broader IMSS audit. Auditors can review the past five years of contribution history.

Employee legal claims

An employee with a housing loan application pending cannot proceed if employer contributions are missing. Employees can and do file formal complaints with INFONAVIT against non-compliant employers.

Joint liability under the 2021 outsourcing reform

If you use a service provider or subcontractor without active REPSE registration, and that provider fails to make INFONAVIT contributions, your company may be jointly liable for the unpaid amounts.

This is a specific compliance risk for companies using informal staffing arrangements or unregistered EOR providers.

For context on how REPSE applies to employment arrangements in Mexico, the what is REPSE in Mexico article explains the 2021 reform framework in full.

INFONAVIT and remote employees (NOM-037)

NOM-037-STPS-2023, Mexico's mandatory telework standard, does not change INFONAVIT obligations. Remote employees receive the same 5% employer INFONAVIT contribution as on-site employees.

However, remote employment does affect how the SBC is calculated when utility stipends are included.

Under NOM-037, employers must provide a monthly proportional stipend for internet and electricity to remote employees. This stipend is issued as a separate CFDI payroll line item.

If the stipend is structured and stamped correctly as a non-salary payment, it does not enter the SBC calculation and does not increase INFONAVIT contributions.

If it is misclassified as salary, it inflates the SBC and increases all contribution obligations.

Correct CFDI 4.0 classification of remote work stipends is an area where payroll errors frequently occur.

INFONAVIT for foreign companies hiring in Mexico

A foreign company cannot register directly with INFONAVIT without first establishing a Mexican legal entity.

Setting up that entity requires RFC registration with SAT, IMSS employer registration, INFONAVIT enrollment, and bank account setup.

The process takes 3–6 months and costs $20,000–$60,000+ before a single employee can be hired.

For companies that want to hire in Mexico without building that infrastructure, the path is through an Employer of Record.

The EOR is already registered with INFONAVIT. When your employee is onboarded, the EOR registers them under its existing employer account.

The EOR remits the 5% contribution on every bimonthly cycle and manages all SUA filings.

Your company receives a single all-inclusive invoice. The EOR handles the entire contribution chain.

What to verify about your EOR's INFONAVIT compliance

When evaluating an EOR provider for Mexico, confirm:

• Active IMSS and INFONAVIT registration: The EOR must have an active Registro Patronal with both institutions

• Active REPSE registration: Required under the 2021 outsourcing reform; without it the arrangement may be classified as illegal subcontracting

• CFDI 4.0-compliant payroll receipts: Each employee's payslip must show INFONAVIT contributions correctly stamped and filed

• SBC accuracy: The EOR must calculate each employee's SBC correctly, including integration factor and annual recalculation

• Bimonthly SUA filings on schedule: Late filings accrue surcharges that are typically passed back to the client

The payroll compliance and hiring checklist for Mexico covers all employer filing obligations including INFONAVIT alongside IMSS and SAT.

How INFONAVIT interacts with other mandatory benefits

INFONAVIT does not operate in isolation. It is part of an integrated payroll compliance stack where each element affects the others.

INFONAVIT and aguinaldo

The SBC integration factor includes the prorated value of the annual aguinaldo (Christmas bonus). This means every time the SBC is calculated, it already accounts for the employee's annual bonus obligation.

For a full breakdown of how aguinaldo is calculated and paid, the mandatory aguinaldo Christmas bonus in Mexico covers the full formula.

INFONAVIT and vacation premium

The vacation premium (prima vacacional, minimum 25% of vacation pay) is also embedded in the SBC integration factor.

As the employee's vacation entitlement increases with seniority, the integration factor rises, which increases the INFONAVIT base.

INFONAVIT and PTU profit-sharing

PTU (Participación de los Trabajadores en las Utilidades) is calculated separately from the SBC and does not directly affect INFONAVIT contributions.

The profit-sharing in Mexico (PTU) guide covers how PTU is calculated and distributed.

INFONAVIT and ISR withholding

INFONAVIT contributions are employer-paid and do not affect the employee's ISR (income tax) withholding.

ISR is calculated on the employee's gross taxable salary, not on any employer contribution. The what is ISR in Mexico article explains how income tax withholding works alongside payroll contributions.

Frequently asked questions

What is INFONAVIT in Mexico?

INFONAVIT is Mexico's national housing fund institute. Employers contribute 5% of each employee's integrated daily salary (SBC) every two months.

The accumulated balance gives employees access to home purchase loans or supplements their retirement savings.

Is INFONAVIT paid by the employer or the employee?

INFONAVIT is paid entirely by the employer. Employees do not have a deduction for INFONAVIT on their payslip.

It is an additional employer obligation on top of gross salary, similar to IMSS employer contributions.

What is the INFONAVIT contribution rate in Mexico?

The rate is 5% of the Salario Base de Cotización (SBC). The SBC is the employee's integrated daily salary.

It includes base pay plus the prorated value of aguinaldo and vacation premium, multiplied by 30 days per month.

When must INFONAVIT contributions be paid?

INFONAVIT contributions are remitted bimonthly through the SUA system, by the 17th of the month following each two-month period. For example, contributions for January and February are due by March 17.

What happens if an employer does not pay INFONAVIT?

Late or missing INFONAVIT payments trigger automatic monthly surcharges (currently 1.47% per month of the unpaid amount) and potential fines.

They also increase the risk of a broader IMSS audit covering up to five years of contribution history.

Can a foreign company pay INFONAVIT directly?

No. Foreign companies without a Mexican legal entity cannot register with INFONAVIT. An Employer of Record with active IMSS and INFONAVIT registration handles all contributions on the foreign company's behalf.

Does INFONAVIT apply to remote employees in Mexico?

Yes. Remote employment does not exempt an employer from INFONAVIT contributions. The 5% applies to all employees regardless of work location.

NOM-037 utility stipends must be correctly classified in CFDI payroll to avoid inflating the SBC base.

What is the INFONAVIT SBC cap in 2026?

The INFONAVIT contribution base is capped at 25 UMA units per day. At the 2026 daily UMA of MXN 117.31, the daily SBC cap is MXN 2,932.75.

Employees above this threshold have INFONAVIT contributions calculated on the capped amount, not the full integrated salary.
