What Is a Deduction? Types, Meaning & Calculation

Salary deduction refers to the amount an employer subtracts from an employee’s gross salary each month before disbursing the final salary (CTC). This payroll deduction includes mandatory government taxes as well as voluntary deductions(such as medical insurance, 401(k) deduction in the USA, or retirement plans).

Understanding these paycheck deductions is essential for both employees and HR teams to ensure accurate salary processing and payroll compliance.

Types of Salary Deductions

Employee Provident Fund: This is a retirement savings scheme for employees. Every month, both the employer and the employee contribute an equal amount to the employee’s EPF account (including a percentage of basic salary and dearness allowance). The EPF deduction is reflected in the salary slip breakup each month.

Income Tax: Employers deduct the income tax at source (TDS) from employees’ salaries based on their income and the applicable tax slabs. This is deposited with the government and directly affects the gross to net salary calculation.

Loan Repayments: When employers provide loans to employees in cases for purposes such as education, home purchases, or other needs. Repayments are made through CTC deductions, reducing the net take-home salary.

Medical insurance: If employers offer a health insurance plan, the premium is usually deducted from the employee’s salary. This helps protect employees against unexpected medical expenses and emergencies.
