4. Sir,
I observe the following reasons for abatements:
(1) Where the value of the goods cannot be segregated easily i.e. Constructions Services (All), Mandap keeper, Restaurant Service, Erection, Commissioning etc.
(2) For the convenience of Assessee : Whether to opt for either Cenvat Credit or abatement ?
Thereafter, trend changed. Govt wanted to reduce rate in the guise (form) of abatement GTA, Tour Operators, Man Power. There was hullabaloo by transporters through out India in 2004.
(3) Ultimately goal was to plug the leakage of revenue by reduction rate in the form of abatements.
(4) Ultimately the burden is to be borne by the consumers, so the Govt. intended to give relief to consumers through assessees.
Why abatement has not been provided to all services ? Govt.requires taxes to run the country. Whatever relief was possible within reasonable limits without hazards to exchequer has been given and, moreover, practically it is impossible to allow the public to turn the exchequer into booty.
Only wearer knows where the shoe pinches. Only Govt. knows how it is difficult to grant relief without hitting the overall interest of the public of all classes.
