Annual incentives not paid by company after resignation, saying my performance is not good

You are welcome.

Hi,

Is it legal to keep Rs.1,20,601/- as annual incentives (performance based) from total annual package of Rs.9,51,437/-..?? This money is mentioned in my increment letter/salary breakup & company is not paying me anything extra. 

Just wanted to know as per government law how much amount an employer can block on the name of annual incentives (which will be paid later based on performance)..?? There should be some limit on this amount, what is that limit..??
