If a company say X LTD is exclusively engaged in "exempted supply or non levy supply" .... and is taking directorship services (falling under RCM) ..Now if we see sec 23 -- persons not liable for registration..which.. says that person making 👆such kind of supply are not liable for registration!!! but while paying director fees the company on RCM have to compulsorily make registeration...So ultimately my question is whether the company is required to register or not..!!???
Please explain...
THANK YOU
