Dear Sh.Sunil Ji,
(1) GST (CGST & SGST ) cannot form part of transaction value/taxable value in terms of Section 15 (2)(a) of CGST Act, 2017 for the purpose of payment of GST. It is clearly mentioned therein.
Section 15(2)(a) of CGST Act reads as follows:-
(2) The value of supply shall include -
(a) any taxes, duties, cesses, fees and charges levied under any law for the time being in force other than this Act, the State Goods and Services Tax Act, the Union Territory Goods and Services Tax Act and the Goods and Services Tax (Compensation to States) Act, if charged separately by the supplier.
(2) Any agreement or contract cannot be executed in violation of CGST Act. Here CGST Act will prevail over Indian Contract Act. Notwithstanding the agreement/contract executed between the supplier and receiver, GST has to be excluded from taxable value for computation of GST. not to be paid on gross invoice value. There is no dispute about. It is free from any doubt.
(3) As per AAR Maharashtra (Applicant : North American Coal corporation India Pvt.) reported as2018 (18) G.S.T.L. 525 (A.A.R. - GST) = 2018 (10) TMI 1339 - AUTHORITY FOR ADVANCE RULING - MAHARASHTRA decided on 11.7.18
