Dinesh's calculation and legal point is correct, but I want to push back slightly on one thing — don't assume 240 days automatically saves you without checking your specific employment contract and company policy.
The 240-day rule comes from judicial interpretation, not a black-and-white line in the Act itself. Most of the time it holds up, but if a company wants to fight it, they will, and you'd need to go to the Labour Commissioner or even civil court. For ₹1.1 lakh, many people just don't bother.
What I'd actually suggest: before your resignation, quietly check if your offer letter or employee handbook mentions gratuity terms. Some companies, especially larger ones, have more generous policies — full 5-year gratuity after 4 years of service, no questions asked. You might be in a better position than you think.
Also one practical thing — don't resign and then ask about gratuity. Send a formal email to HR and your reporting manager before submitting resignation, asking them to confirm your gratuity eligibility given your tenure. Get it in writing. Once you've resigned, your leverage drops significantly.
The tax angle also matters: gratuity up to ₹20 lakh is fully tax-exempt for private sector employees under Section 10(10) of the Income Tax Act. So whatever you receive, you keep it all.
My honest take — 4 years 10 months is strong ground. Send that email first, get a written confirmation, then resign.
