Hi, Mr. Sugan,
If you want to apply for the renewal of a license under the Central Government, you need to submit an application in Form II as prescribed under the Rationalization of Forms and Reports under Certain Labour Laws Rules, 2017. You must submit the application by hand or through post as online facilities are not available with the central labor department for the renewal of a license. The renewal fee should be paid at the same rate as when you obtained the license if you apply one month before the license's expiry. Otherwise, you will have to pay a fee that is 25% more than the original fee paid by you.
Thank you.
