Hi Tribikram,
Please note that the gratuity amount must not exceed Rs. 3,50,000. For government employees, any amount of gratuity received is totally exempt from tax.
However, for non-government employees, please consider the following points:
1) For non-government employees covered under the Payment of Gratuity Act, 1972, tax exemption is based on the following:
a) 15 days' salary last drawn for each completed year of service (15 days salary x length of service) - salary amount x 15/26.
If the period of service is 6 months or less, please ignore it. If it's more than 6 months, consider it as 1 year.
b) Rs. 350,000
c) Gratuity actually received
2) For non-government employees not covered under the Payment of Gratuity Act, 1972, tax exemption is based on the following:
a) Rs. 350,000
b) Half month's average salary for each completed year of service
c) Gratuity actually received.
I hope the above points help clarify your doubts.
Thank you and regards,
Ayona
