How to compute ‘aggregate turnover’ to determine eligibility for composition scheme?

The methodology to compute aggregate turnover is given in Section 2(6). Accordingly, ‘aggregate turnover’ means value of all outward supplies (taxable supplies +exempt supplies +exports + inter-state supplies) of a person having the same PAN and it excludes taxes levied under central tax (CGST), State tax (SGST), Union territory tax (UTGST), integrated tax(IGST) and compensation cess. Also, the value of inward supplies on which tax is payable under reverse charge is not taken into account for calculation of ‘aggregate turnover’.
