Hi Smitha,
Lenvica HRMS helps you automate the professional tax calculation for Kerala. As you process payroll, professional tax gets automatically calculated as per the rules. Lenvica HRMS also has a report that describes professional tax to be paid, and the amount to be deducted from employees each month. Since the professional tax has to be paid even before salary is processed for August and September in the first half-year(February and March in the second half-year), the software uses data projection to arrive at half-yearly wages out of which the professional tax is calculated. The report even includes a calculation history for you to understand how professional tax is calculated for each employee.
