fiscal_calendario

Obligaciones fiscales y fechas limite de un regimen fiscal mexicano. Con `mes` (1-12) calcula la fecha limite del pago mensual de ese periodo (dia 17 del mes siguiente, ajustado al siguiente dia habil por fin de semana). Con `rfc6` (6o digito del RFC) estima la extension del decreto de facilidades. Informativo, no asesoria fiscal.

fiscal_cfdi_validar

Valida la coherencia de un CFDI 4.0 antes de emitirlo: relacion entre tipo de comprobante, uso, metodo/forma de pago y tipo de receptor, contra los catalogos del SAT. Determinista. NO timbra ni sustituye al PAC. Informativo, no asesoria fiscal.

fiscal_finiquito

Calcula finiquito (renuncia/termino) o liquidacion (despido injustificado), LFT: aguinaldo proporcional, vacaciones + prima, y para liquidacion 3 meses + 20 dias/anio + prima de antiguedad. Devuelve montos BRUTOS. La procedencia legal y el ISR se confirman con abogado/contador. No asesoria.

fiscal_imss

Calcula las cuotas IMSS obrero-patronales del periodo sobre el SBC diario (topado a 25 UMA): Enfermedades y Maternidad, Invalidez y Vida, Retiro, Cesantia y Vejez (curva patronal 2026 por veces UMA), Guarderias, Riesgos de Trabajo e INFONAVIT. Determinista. Da sbc_diario o salario_diario. Estimacion (la prima RT es por empresa; los dias reales dependen del mes). Informativo, no asesoria.

fiscal_isr_estimado

ESTIMA el ISR anual segun regimen, ingresos y deducciones, con la tarifa progresiva Art. 152 (Anexo 8 RMF 2026) o la tasa aplicable (RESICO/PM). Es una ESTIMACION: el ISR real depende de deducciones exactas, acreditamientos y pagos provisionales. Informativo, no asesoria fiscal.

Calcula recargos por mora + actualizacion por pago tardio de una contribucion en Mexico (CFF Art. 17-A y 21). Determinista y auditable.

fiscal_regimen_factores

Devuelve los FACTORES para elegir regimen fiscal en Mexico (topes de ingreso, base gravable, tasas, exclusiones) segun tipo de persona, ingresos anuales y actividad. INFORMA, NO DECIDE: nunca recomienda un regimen; la eleccion es del contribuyente con su contador. Informativo, no asesoria fiscal.

fiscal_valores_vigentes

Devuelve los valores fiscales vigentes verificados de Mexico para un anio (UMA, salario minimo, tasas de recargo y parcialidades), cada uno con su fuente oficial. Es el 'moat': datos mantenidos y verificados contra DOF/LIF/CFF. Informativo, no asesoria fiscal.
