Sir/Madam,
In this regards, my point of view is as follows:-
1. If any business entity is receiving legal service from an Advocate of Firm of Advocate in terms of Notification No. 13/2017-CT (Rates) dated 28th June, 2017 Sl.No.2 and its corrigendum, then GST is payable under RCM by the business entity in taxable territory. The legal service has been defined by way of explanation “legal service” means any service provided in relation to advice, consultancy or assistance in any branch of law, in any manner and includes representational services before any court, tribunal or authority.”.
1.1 Now if an Advocate is receiving legal service from another Advocate than, it is an exempted service in terms of Sl.No. 45 of Notification No. 12/2017-CT (Rate) dated 28th June,2017.
1.2 If GTA avails the legal service from an Advocate of firm of Advocates, than GTA is required to take registration, if not taken, has to pay the GST and vice a versa, in terms of Section 24(iii) of CGST, Act, 2017.
2. “Casual taxable person” means a person who occasionally undertakes transactions involving supply of goods or services or both in the course or furtherance of business, whether as principal, agent or in any other capacity, in a State or a Union territory where he has no fixed place of business.
2.1 From above it is clear that a person should have a fix place of business in a state. A casual taxable person is one who has a registered business in some State in India, but wants to effect supplies from some other State in which he is not having any fixed place of business. Such person needs to register in the State from where he seeks to supply as a casual taxable person. Therefore, registration in a state is mandatory to become a casual taxable person.
2.2 “aggregate turnover” means the aggregate value of all taxable supplies (excluding the value of inward supplies on which tax is payable by a person on reverse charge basis), exempt supplies, exports of goods or services or both and inter-State supplies of persons having the same Permanent Account Number, to be computed on all India basis but excludes central tax, State tax, Union territory tax, integrated tax and cess.
From above, it is clear that all taxable supplies made by a person having same PAN number on all India basis is to be included in arriving the threshold limit.
I invite our experts to correct me if mistaken.
