Services by way of performance by Musician (Artist) in the Hotel or Club in a Musical night is covered under forward charge upon the Musician (Artist), in my humble view and in such a case, concerned Hotel or Club are not liable to pay GST under RCM.
RCM liability under Serial No. 9 of Notification No. 13/2017- Central Tax (Rate) (as amended from time to time till date) is for 'Supply of services by a music composer, photographer, artist or the like by way of transfer or permitting the use or enjoyment of a copyright covered under clause (a) of sub-section (1) of section 13 of the Copyright Act, 1957 relating to original dramatic, musical or artistic works to a music company, producer or the like.'
These are ex facie views of mine and the same should not be construed as professional advice / suggestion. And I respect contrary views.
