HGST exemption for secondhand goods: dealers under margin scheme exempt from State tax on acquisitions from unregistered suppliers. Exemption of intra State acquisitions of second hand goods from State tax is granted where a registered dealer dealing in buying and selling of second hand goods elects to pay tax on the value of outward supplies under the margin scheme. The exemption applies to purchases received from suppliers who are not registered, removing State tax liability on those inward supplies when the registered dealer determines tax under the margin/second hand valuation mechanism.
