Gst trhesehold limit

Yes, Commission Income is neither exempt from GST not under Zero rated supplies therefore gst is applicable.

As far as registration is concerned you are not required to obtain GST registration Upto receipt of Rs. 20 Lakh. However if you wish to obtain voluntarily then after registration you need to pay GST on every receipt else every receipt will be deemed to be inclusive of GST.

Thanks

Every commission agent is required to register under gst irrespective of turnover.

GST registration is mandatory for all agents. The GST Act states that any persons who make taxable supply of goods or services or both on behalf of other taxable persons whether as an agent or otherwise must be registered under GST.
