In account gratuity provision for new company in first year

The applicability of Gratuity arises only when the employee has been with the organisation for five or more years. Since yours is a start up, you can create this provision now because the future outflows are after five years. If it is mandatory to create the provision from beginning, then disclose the 1 months gratuity adjustments, and mention how much you’re providing. 

To me, this sounds fine.
