Dear Nikita,
As per Section 79 of Factories Act 1948, it is enumerated that :-
Provided that the total number of days of leave that may be carried forward to a succeeding year shall not exceed thirty in the case of an adult or forty in the case of a child.

However there has been recent amendments in 2002 via The Small Enterprises( Employment Relations) Act 2002 which is applicable to whole of India.
Under chapter IV - conditions of work , clause no 11 point 4 mentions that
A worker shall be permitted to accumulate leave upto 45 days in addition to the leave entitlement of the current year earned on the basis of the work done by him in the previous year and he shall be entitled to encashment of entire accumulted earned leave including leave earned during the current year pro rata in case his services are terminated or he quits the service.
