This is an option available to small businesses and taxpayers having a turnover less than Rs. 50 lakhs. They can opt for Composition scheme where they will tax at a nominal rate of 1% or 2.50% (for manufacturers) CGST and SGST each (rates will be notified later).
They will be required to maintain much less detailed records and file only 1 quarterly return instead of three monthly returns. However, they cannot issue taxable invoices, i.e., collect tax from customers, but are required to pay the tax out of their own pocket. They cannot also claim any input tax credit.
Composition levy is available to only small businesses. It is not available to interstate sellers, e-commerce traders, and operators.
