Hi Murthy,
What type of operations is your factory engaged in? First of all, you should have fresh registration or an amendment to the existing registration as the case may be, such as:
1. PAN/TAN/TIN/GST No. (all fresh or amendments to registrations)
2. Labour license/EPF/ESIC registrations (may be an amendment to an existing registration)
3. Professional Tax registration (fresh registration)
4. If yours is a company registered under the Companies Act, an amendment to the Certificate of Registration is necessary by re-constituting the Board of Directors.
5. A formal resolution in the Board meeting should be passed relevant to the change of authorized authorities, Factory Manager, and certified resolutions shall be submitted to the Registrar of Companies, Banks, Auditors.
6. Similar resolutions shall be submitted to the Inspectors of Factories/Fire Safety officers, Assistant Labour Commissioner, and municipal authorities.
