The National Anti-Profiteering Authority (NAA) is required to determine whether the benefit of input tax credit or reduction in the tax rate has actually resulted in a commensurate reduction in the price of the goods or services or both.

The NAA has the power to identify the registered person who has not passed on the benefit of reduction in tax rate or input tax credit by way of commensurate reduction in prices and it may order reduction in prices; return to the recipient, an amount equivalent to the amount not passed on by way of commensurate reduction in prices along with interest; cancellation of registration of the supplier and imposition of penalty. In case the eligible recipient is not identifiable or does not claim return of the amount, the NAA may order the supplier to deposit the amount in the Consumer Welfare Fund.
