Reverse Charge Mechanism

If  you are taking  security  services  and paying  tax under RCM  , then as per section 24(iii) of the CGST  act 2017  registration is compulsory .  

please confirm with others also. 

Security services (services provided by way of supply of security personnel) provided to a "registered person" .As per the wordings of provision , rcm has to be paid by registered person only and you are unregistered .Sec 24(iii) applies when there is liability to pay tax under reverse charge arises. Since in this case no liability arise. So no registration required.. This is my opinion and view. Please confirm others as well. Thanks

Reply of Mr Prasad nilgul is correct. If you are taking any goods or services which are liable to pay tax under RCM then you have to Lake registration
