Resolution
The amount of exemption over food vouchers’ (wage type /360) calculation can be seen below:
Minimum salary (table V_T7MX62)
40% of the minimum salary: minimum salary * 40% = X MXN
/360: X MXN * number of days (V_T510H) = Y MXN
Example
Minimum salary: 80,04
40% of the minimum salary: 80,04 * 40% = 32,016 MXN
/360: 32,016 MXN * 7 = 224,112 MXN
The system does not calculate exemption for the days of the month. It only calculates exemption for the days of the period. For this reason, the amount of exemption may not be correct when the pay period is weekly.
It happens, because food vouchers are cumulated on a monthly basis for the weekly payroll.
This issue can be solved through customer rules, customizing or by programming the corresponding exit user exemptions of the IMSS.
