Wish there is an option to easily maintain and track previous year "coeficiente de utilized fiscal" (profit tax factor to be applied on "pagos provisionales on ISR tax profit sharing"

Example:
Ingresos acumulables: 800,000
(-) Deducciones autorizadas: 450,000
=Utilidad fiscal $350,000

Ingresos nominales
Ingresos acumulables: 800,000
-ajuste anual por inflación 42750
=Ingresos nominales=$757,250

Coeficiente de utilidad
Utilidad fiscal $350,000
/ divided by ingresos nominales: $757,250
=.4622 factor to be applied on ISR tax payment for next year.
