Generate CFDI de Nómina XML (complemento Nómina 1.2)

Skill: Convert a payroll run into a CFDI 4.0 with the Nómina 1.2 complemento, stamped by a PAC

Region: Mexico (México) Category: Payroll — Recibo de nómina (CFDI de Nómina) Does: Takes payroll data for an employee/period and produces a CFDI de Nómina — a cfdi:Comprobante (Version 4.0, TipoDeComprobante="N") carrying the complemento Nómina 1.2 (nomina12:Nomina) with Percepciones, Deducciones and OtrosPagos (including subsidio al empleo) — then stamped (timbrado) by a PAC which returns the TimbreFiscalDigital with the UUID. Standard: SAT CFDI 4.0 (Anexo 20) + complemento Nómina 1.2

Every salary payment in Mexico must be documented with a stamped CFDI de Nómina; the employee's CFDIs feed the SAT's prefilled annual ISR return. The Emisor is the employer (with RegistroPatronal from IMSS), the Receptor is the worker (with Curp, NumSeguridadSocial, TipoContrato, TipoRegimen, etc.). All TipoPercepcion, TipoDeduccion and TipoOtroPago codes come from the current SAT nómina catálogos (c_TipoPercepcion, c_TipoDeduccion, ...). Validate against the Anexo 20 + Nómina 1.2 XSDs before stamping.

When this applies

Any payment of salaries, wages, assimilated income, severance, bonuses (aguinaldo), PTU, etc., to a worker.
TipoNomina = O (Ordinaria — regular periodic payroll) or E (Extraordinaria — aguinaldo, finiquito, liquidación, PTU).
The CFDI must be issued at payment and stamped within the SAT window; corrections re-issue with substitution (relación 04).

Input data required

Input	Node / attribute
Employer RFC, name, regime, ZIP, IMSS registro patronal	`Emisor@Rfc/@Nombre/@RegimenFiscal`, `nomina12:Emisor@RegistroPatronal`
Worker RFC, name, CURP, NSS	`Receptor@Rfc/@Nombre`, `nomina12:Receptor@Curp`, `@NumSeguridadSocial`
Employment data	`@FechaInicioRelLaboral`, `@Antiguedad`, `@TipoContrato`, `@TipoRegimen`, `@NumEmpleado`, `@Departamento`, `@Puesto`, `@RiesgoPuesto`, `@PeriodicidadPago`, `@SalarioDiarioIntegrado`
Period	`nomina12:Nomina@TipoNomina`, `@FechaPago`, `@FechaInicialPago`, `@FechaFinalPago`, `@NumDiasPagados`
Earnings	`Percepciones/Percepcion` (TipoPercepcion, Clave, Concepto, ImporteGravado, ImporteExento)
Deductions	`Deducciones/Deduccion` (TipoDeduccion, Clave, Concepto, Importe) — ISR (`002`), IMSS (`001`)
Other payments	`OtrosPagos/OtroPago` (TipoOtroPago `002` = subsidio para el empleo → `SubsidioAlEmpleo@SubsidioCausado`)

Mexican specifics: TotalGravado/TotalExento totals must equal the sum of the per-line gravado/exento amounts; the CFDI SubTotal/Descuento/Total reconcile against percepciones, otros pagos and deducciones.

Document structure

cfdi:Comprobante (Version=4.0, TipoDeComprobante=N, Moneda=MXN, SubTotal, Descuento, Total)
├── cfdi:Emisor / cfdi:Receptor
├── cfdi:Conceptos/cfdi:Concepto (ClaveProdServ=84111505, ClaveUnidad=ACT, ObjetoImp=01)
└── cfdi:Complemento
    └── nomina12:Nomina (Version=1.2, TipoNomina, FechaPago, NumDiasPagados, TotalPercepciones, TotalDeducciones, TotalOtrosPagos)
        ├── nomina12:Emisor (RegistroPatronal)
        ├── nomina12:Receptor (Curp, NumSeguridadSocial, TipoContrato, TipoRegimen, SalarioDiarioIntegrado, ...)
        ├── nomina12:Percepciones (TotalGravado, TotalExento; Percepcion[])
        ├── nomina12:Deducciones (TotalImpuestosRetenidos; Deduccion[])
        └── nomina12:OtrosPagos/OtroPago/nomina12:SubsidioAlEmpleo

The PAC then appends tfd:TimbreFiscalDigital (UUID).

Calculation rules

Percepciones/@TotalGravado = Σ Percepcion@ImporteGravado; @TotalExento = Σ @ImporteExento. @TotalSueldos groups ordinary salary percepciones.
Deducciones/@TotalImpuestosRetenidos = Σ ISR deduction (TipoDeduccion=002); @TotalOtrasDeducciones = Σ non-tax deductions (IMSS, loans, etc.).
Nomina/@TotalPercepciones = TotalGravado + TotalExento; @TotalDeducciones and @TotalOtrosPagos mirror their sections.
Subsidio al empleo is reported under OtrosPagos (TipoOtroPago=002) with SubsidioAlEmpleo@SubsidioCausado, not as a percepción.
CFDI Total = TotalPercepciones + TotalOtrosPagos − TotalDeducciones (net pay); SubTotal = TotalPercepciones + TotalOtrosPagos; Descuento = TotalDeducciones.
ISR is computed on the gravado portion per the SAT tariff for the PeriodicidadPago.
