States gave up many taxing powers in return for a share in a pooled tax decided jointly in the GST Council. A five-year GST compensation was promised for revenue losses.
Where to go next
- GST Council: Joint decision-making on GST
- GST compensation: Guaranteed revenue to States
In one line: GST improved tax compliance but reduced States' fiscal autonomy.
Gains
Cascading taxes removed, e-way bills and a larger tax base.
Concerns
Multiple rates, the Centre's effective veto, and loss of State taxing power after GST compensation ended in 2022. The Supreme Court held in 2022 that GST Council recommendations are persuasive, not binding.
Where to go next
