Registration of insurance agent

If person already registered then he should add this service by filing application for amendment of registration. The provisions relating to amendment of registration are contained in Section 28 r/w rule 19 of CGST Rules, 2017.

Further, even though it is service covered under RCM it needs to be disclosed in GSTR-1 in B2B section. While adding invoice in GSTR-1 person has to select option 'Supply attracting Reverse Charge'.

As per Notification 13/2017 CT (R) It's under RCM & Receptient insurance company is liable to do RCM.

But as per your query he is doing business & also providing insurance services. So in case if you are registered then need to report Insurance Services in GST Return.
