<h1>RSP-based valuation of notified tobacco goods: report net sale value as taxable value and tax per RSP formula.</h1> For notified tobacco goods, tax liability must be determined from the RSP using Tax Amount = (RSP x GST rate) / (100 + GST rate) and Deemed Taxable Value = RSP - Tax Amount. Due to transaction-value system validations, taxpayers should report the Net Sale Value (actual commercial consideration) in the taxable value field, report the tax amount computed strictly under the RSP formula, and report Total Invoice Value as Net Sale Value plus the RSP-derived tax amount; these fields are self-assessed and limited to the specified HSNs.
