INFONAVIT Employee Registration Form Mexico (Inscripción de Trabajador al INFONAVIT)

An INFONAVIT Employee Registration Form Mexico (Inscripción de Trabajador al INFONAVIT) is the administrative document used to formally enrol a worker in the Instituto del Fondo Nacional de la Vivienda para los Trabajadores (INFONAVIT) system, activating the employer's obligation to contribute 5% of the worker's Salario Diario Integrado (SDI) to the worker's individual housing subcuenta (subcuenta de vivienda). The registration is governed principally by Article 29 of the Ley del INFONAVIT, published in the Diario Oficial de la Federación on 24 April 1972 and subsequently reformed multiple times, most significantly in 1992 and 2012 to integrate the INFONAVIT subcuenta into the Sistema de Ahorro para el Retiro (SAR) managed by the Comisión Nacional del Sistema de Ahorro para el Retiro (CONSAR).

INFONAVIT operates as a tripartite institution — governed by representatives of employers (patrones), workers (trabajadores), and the federal government — with the constitutional mandate derived from Article 123, Apartado A, Fracción XII of the Constitución Política de los Estados Unidos Mexicanos of 5 February 1917, which requires employers to provide workers with comfortable and hygienic housing, an obligation converted into a monetary contribution mechanism by the creation of INFONAVIT in 1972. The INFONAVIT Consejo de Administración sets housing credit policies, interest rates (in VSM — veces de salario mínimo — or pesos depending on the credit type), and annual contribution parameters.

In practice, INFONAVIT worker registration is inseparable from IMSS registration — both are processed through the same IMSS Empresarial portal and through the SUA (Sistema Único de Autodeterminación) software. When an employer files an Alta de Trabajador (worker registration) with the IMSS under Article 15 of the Ley del Seguro Social, the IMSS simultaneously transmits the worker's data to INFONAVIT, activating the INFONAVIT subcuenta de vivienda. The worker's INFONAVIT account is linked to their NSS (Número de Seguridad Social) and CURP (Clave Única de Registro de Población), the same identifiers used for IMSS registration.

The INFONAVIT subcuenta de vivienda accumulates as an individual account within the worker's AFORE (Administrador de Fondos para el Retiro) under the SAR system. Employer INFONAVIT contributions are deposited in this subcuenta quarterly — although the SUA bimonthly payment cycle is used for remittance, INFONAVIT credits the subcuenta quarterly in alignment with the SAR reporting cycle. Workers accumulate INFONAVIT points (puntos INFONAVIT) based on their age, salary level, and continuous contribution history — upon accumulating sufficient points, the worker qualifies for an INFONAVIT housing credit (crédito INFONAVIT) to purchase, build, renovate, or pay off an existing mortgage.

The Secretaría del Trabajo y Previsión Social (STPS) and INFONAVIT jointly conduct employer inspections to verify contribution compliance. Under Article 56 of the Ley del INFONAVIT, INFONAVIT has independent inspection and enforcement authority, and can issue employer fines (multas) and initiate execution proceedings (procedimiento económico-coactivo) to collect unpaid contributions. The Procuraduría de la Defensa del Trabajador (PROFEDET), a federal agency under the STPS, assists workers in claiming unpaid INFONAVIT contributions from non-compliant employers before the Tribunales Laborales.

The INFONAVIT registration form serves as the internal employer record confirming the worker's INFONAVIT registration status, the SDI used for contribution calculation, and the commencement of the employer's contribution obligation. While INFONAVIT registration itself is processed electronically through IMSS Empresarial, the internal registration form is essential for payroll department records, labour inspection compliance, and worker communication regarding their housing fund rights.

An INFONAVIT Employee Registration Form Mexico is required whenever a new worker begins employment with a Mexican employer subject to the Ley del INFONAVIT. Article 29 of the Ley del INFONAVIT creates the employer's housing fund contribution obligation from the first day of the employment relationship — the same day the employer's IMSS registration obligation arises under Article 15 of the Ley del Seguro Social. Because IMSS and INFONAVIT registrations are processed simultaneously through IMSS Empresarial, the INFONAVIT registration is triggered by the same Alta de Trabajador filing that initiates IMSS coverage.

The INFONAVIT registration form is needed for all workers who are subject to the Apartado A of Article 123 of the Constitución Política — that is, all private-sector workers in Mexico regardless of their employment contract type, salary level, or nationality. Foreign workers with valid work authorization (permiso de trabajo) from the Instituto Nacional de Migración (INM) and a valid RFC assigned by the SAT are subject to the same INFONAVIT contribution obligations as Mexican nationals. Workers holding Tarjeta de Residencia Temporal con permiso para trabajar or Tarjeta de Residencia Permanente are fully subject to INFONAVIT.

The form is required when documenting the internal HR records of a worker's INFONAVIT registration for payroll compliance purposes. Although the electronic registration through IMSS Empresarial generates an acuse de recibo as the official IMSS record, Mexican employers are required under Article 804 of the Ley Federal del Trabajo to maintain payroll and employment documentation for at least one year following termination — and STPS inspection visits routinely examine whether employer HR files contain evidence that INFONAVIT obligations were acknowledged and actioned.

INFONAVIT registration documentation is required when a worker requests a Constancia de Semanas Cotizadas (certificate of contribution weeks) from IMSS or a statement of INFONAVIT housing subcuenta balance — both of which the worker needs when applying for an INFONAVIT credit. The employer's cooperation in certifying the worker's registered SDI and employment start date is part of the INFONAVIT credit application process under the Reglamento de Inscripción, Pago de Aportaciones y Entero de Descuentos al INFONAVIT.

The registration form is particularly important for workers in the construction sector (sector de la construcción) where worker-employer relationships are often project-based and employers must demonstrate compliance with INFONAVIT contribution obligations for each project worker through detailed payroll and IMSS records. The Cámara Mexicana de la Industria de la Construcción (CMIC) and INFONAVIT have joint protocols for construction sector INFONAVIT compliance monitoring.

A valid INFONAVIT Employee Registration Form Mexico under Article 29 of the Ley del INFONAVIT must contain the following essential elements to serve as a complete internal record of the worker's INFONAVIT registration and the employer's housing fund contribution commitment.

Employer Identification: The full legal name (razón social) of the employer, the Registro Patronal (IMSS employer registration number assigned upon Alta Patronal), the RFC (Registro Federal de Contribuyentes assigned by the SAT), and the employer's fiscal domicile. The Registro Patronal is the primary link between the employer's records and the IMSS and INFONAVIT electronic systems — it must match the employer's registered Registro Patronal exactly for all electronic filings through IMSS Empresarial to be accepted.

Worker Identification: The worker's full legal name (nombre completo), NSS (Número de Seguridad Social — 11 digits, the permanent IMSS-assigned identifier), CURP (Clave Única de Registro de Población — 18 alphanumeric characters issued by RENAPO), RFC (13 characters for individuals, assigned by the SAT), nationality, and date of birth. The date of birth is used by INFONAVIT to calculate the worker's age-based points under the INFONAVIT credit scoring system — older workers accumulate points faster, reflecting the policy objective of prioritizing housing access for workers closer to retirement age.

Employment Start Date (Fecha de Inicio de la Relación Laboral): The date the employment relationship began, which is the same date used for the IMSS Alta de Trabajador filing and marks the start of the employer's INFONAVIT contribution obligation. This date is recorded in the INFONAVIT system as the beginning of the worker's contribution history with this employer.

Registered Daily Integrated Salary (Salario Diario Integrado — SDI): The SDI calculated under Article 84 of the Ley Federal del Trabajo, integrating base daily wage plus proportional values of aguinaldo, prima vacacional, and other recurring benefits. The SDI is the basis for calculating the employer's 5% INFONAVIT contribution under Article 29 of the Ley del INFONAVIT. The SDI registered for INFONAVIT purposes must match the SDI registered with the IMSS — any discrepancy between the two registered figures is an audit red flag for both IMSS and INFONAVIT inspectors.

Job Title and Category (Puesto y Categoría): The worker's position and occupational category. INFONAVIT uses job category information for statistical reporting on workforce composition by sector, and in the construction sector specifically, the job category determines applicable collective contribution tables under CMIC-INFONAVIT protocols.

INFONAVIT Contribution Acknowledgment: A clear statement that the employer acknowledges its obligation to contribute 5% of the worker's SDI to the INFONAVIT housing subcuenta each bimonthly period through the SUA payment system, and to remit any INFONAVIT credit deductions (descuentos por crédito INFONAVIT) from the worker's paycheck to INFONAVIT if the worker has an active INFONAVIT credit under Article 42 of the Ley del INFONAVIT.

Worker Rights Notice (Aviso de Derechos del Trabajador): Confirmation that the worker has been informed of their right to accumulate INFONAVIT points toward a housing credit, to query their subcuenta balance through the INFONAVIT worker portal (Mi Cuenta INFONAVIT), and to designate beneficiaries for the subcuenta balance in case of death under the Ley del INFONAVIT.

Forms-legal.com provides this INFONAVIT Employee Registration Form Mexico template as an internal HR documentation guide. INFONAVIT contribution compliance is monitored through both the SUA bimonthly payment system and periodic INFONAVIT employer inspections — employers should maintain accurate SDI records and ensure timely SUA payments to avoid INFONAVIT enforcement actions under Article 56 of the Ley del INFONAVIT, which grants INFONAVIT coercive collection powers equivalent to those of a federal tax authority.
