Dear Sir,
Let me discuss it in detail. As per the definition of legal services provided under Rule 2(1)(cca) "legal services means any service provided in relation to advice, consultancy or assistance in any branch of law, in any manner, and includes representational service before any court, tribunal or authority. it is no where provided in the definition that only advocates as defined under advocates Act, are eligible to provide advice, consultancy and representational services. It is true that only lawyers are eligible to represent in courts. However in case of tribunals and other authorities, lawyers and as well as other persons like CAs are also eligible to represent.
Legal services provided by advocates or a partnership firm of advocates to a business entity having turnover up- to 10 Lacks in preceding financial year is exempted. Legal services provided by advoicate or partnership firm of advocates to a business entity having turnover more than ₹ 10 Lakh in preceding financial year is taxable and such services has been specified under Rule 2(1)(d) of service tax rules, 1994 and Notification no. 30/2012. Because only legal services provided by advocates or partnership firm of advocates are mentioned under Rule 2(1)(d) of service tax rules, 1994, that's why reverse charge mechanism is applicable on legal services provided by advocates.
Service tax consultant and project consultant, who are able to give advice or consultancy in law because of their experience in law, but not acting as an advocate ( i.e. advocate as per advocates Act,) will not be covered under reverse charge mechanism. Meaning thereby such consultant are liable to collect and pay service tax. Such consultant can be treated as legal consultant but services provided by such consultant will not be covered under revere charge mechanism.
regarding CAs, it is very clear that they are governed by ICAI Act, and they can not act as CA and an advocate simultaneously. As Chartered Accountant services are not specified under Rule 2(1)(d) and also not notification no. 30/2012, reverse charge mechanism will not be applicable.
In nutshell, service provided by chartered accountant and service tax consultant and project consultant who are not acting as an advocate, are not covered under reverse charge mechanism.
