Rules regarding salary deduction specify what an employer is legally allowed to deduct out of the gross salary of an employee and then the employer is obliged to compensate the remaining amount as the net salary. These inferences are usually statutory (compulsory) and non-statutory (voluntary).
These are statutory deductions and are mandated by law and might include income tax (TDS), the social security deductions (Provident Fund (PF), Employee State Insurance (ESI), and professional tax (where applicable). These should be computed by the employers in accordance to the governmental regulations, employee income, and the limits. Deductions which are not authorized or are excessive are not permissible.
Non-statutory deductions are optional and they only take place upon the consent of the employees. The examples are health insurance payments, loan payments, pension savings, cafe deductions or uniforms.
Employers are required to act under transparency regulations: it should be explicitly displayed on the payslip of the employee and supported and also recorded. The deductions made on exit or leave encashments should be done in accordance with labor laws and company policies. The aim will be compliance, accuracy and fairness of the employees.
