For the mid month new joiner the annual Conveyance exemption is coming incorrectly

Dear All,

For one of our client, we have have faced a uniqe issue.

If any employee join in the mid of the month, his prorated conveyance amount ( wage type 2020) is coming correctly. Suppose an employee joined at 16th of the month, system is calculating his conveyance for that month as INR 400 and which is correct.

However in his tax calculation for that particular month, system is taking INR 400*(rest of the month of the FY) in the wage type /4E3. which is incorrect. Suppose he joined in 16th April , system is calculating tax exemption 400*12=4800

Now if we run next month payroll ,  system is caculating the exemption properly. i.e. INR 400 + 800* rest of the month of the FY,

Please help

Regards

Tirtha
