Am I entitled to the gratuity if I resign from a limited term contract?

I have been working on a limited contract with a company for 8 years. I kept on renewing the same contract every 2 years.

Last year in April 2017, I renewed the same contract. This year, in March 2018, I resigned from my job and I am serving my notice period for one month.

Will I get my gratuity? Do I have to pay my compensation fee?

I'm a qualified accountant. Can the company put a ban on me?
