30 second summary | The Employees’ State Insurance (ESI) scheme requires employers and eligible employees to contribute a fixed percentage of monthly gross wages. Employers contribute 3.25% and employees 0.75%, calculated on wages up to ₹21,000 per month. These contributions fund medical, sickness, maternity and other social security benefits.

Employees' State Insurance (ESI) contributions are calculated as a percentage of an eligible employee's monthly gross wages, with the employer contributing 3.25% and the employee 0.75%. These contributions, made under the Employees' State Insurance Act, 1948, fund medical care, sickness, maternity, disablement and other social security benefits for covered employees and their families.

ESI applies to non-seasonal factories and specified establishments with 10 or more employees (20 or more in some states) where individual wages do not exceed ₹21,000 per month (₹25,000 for persons with disabilities). Contributions must be deposited with the Employees' State Insurance Corporation (ESIC) by the 15th of the following month.

What are the current ESI contribution rates?

The current ESI contribution rate is 4.00% of eligible monthly wages, with the employer contributing 3.25% and the employee 0.75%.

Note: Employees earning an average daily wage of up to ₹176 are exempt from paying the employee's share of the ESI contribution. However, the employer must continue to pay the employer's 3.25% contribution for these employees.

How is ESI calculated?

ESI is calculated by applying the prescribed employer and employee contribution rates to the employee's monthly gross wages.

  • Employee ESI contribution = Gross wages × 0.75 ÷ 100
  • Employer ESI contribution = Gross wages × 3.25 ÷ 100
  • Total ESI contribution = Employee contribution + Employer contribution

Gross wages are rounded to the nearest rupee before applying the contribution rates. The employee's share is deducted from their salary, while the employer's share is borne separately by the establishment.

ESI eligibility is fixed for each six-month contribution period (1 April to 30 September and 1 October to 31 March) and is determined by the employee's wages at the start of the period. If an employee is covered at the start of a contribution period and their wages later cross ₹21,000 during the period, they remain covered until the end of that period, with contributions continuing on their actual (higher) wages. Coverage ceases only from the start of the next contribution period if their wages are still above ₹21,000 at that point.

What counts as gross wages for ESI purposes?

Gross wages for ESI purposes include most regular cash payments made to an employee, while certain reimbursements, retirement benefits and infrequent payments are excluded.

Special consideration

The following wage components have specific rules that affect how ESI contributions and eligibility are calculated:

  • Overtime wages are included in gross wages for ESI contribution calculations but are not considered when determining the ₹21,000 wage ceiling.
  • Attendance bonus, ex gratia payments, incentive bonus, production bonus and annual bonus are included only if they are paid at intervals not exceeding two months.
  • Conveyance allowance is included when paid as a fixed allowance under the employment contract, but excluded when it is reimbursed for actual travel expenses.
  • Food, milk, tiffin or lunch allowance is included when paid as a fixed cash allowance but excluded when linked to attendance or provided in kind.
  • Education allowance and newspaper allowance are included when paid as monthly allowances, but excluded when reimbursed for actual expenses.

How does ESI calculation work in practice?

ESI is calculated by applying the prescribed employer and employee contribution rates to the employee's gross wages for the wage period.

Component

Amount

Gross wages

₹18,000

Employee ESI (0.75%)

₹135

Employer ESI (3.25%)

₹585

Total ESI contribution

₹720

The employer deposits the total contribution of ₹720 with the Employees' State Insurance Corporation (ESIC) by the 15th of the following month under the employer code.

If the same employee earns ₹21,500 in a month due to a non-recurring payment that is not counted toward the wage ceiling, they may continue to be covered if their wages for ESI eligibility remain at or below ₹21,000. However, if the employee remains covered, any wage components that qualify as ESI wages are included in the contribution calculation for that period.

When are ESI contributions due?

ESI contributions are payable monthly and must be deposited by the 15th of the month following the month in which wages are paid. For example, contributions on wages paid in July must be deposited by 15 August.

ESIC administers these contributions through two contribution periods each year:

  • 1 April to 30 September
  • 1 October to 31 March

Conclusion

Accurate ESI calculation depends on applying the correct contribution rates, identifying eligible wage components and depositing contributions on time. Getting these right helps employers stay compliant and ensures employees continue to receive ESI benefits.
