Rule 32(5) of the CGST Rules (The General Margin Scheme): This rule states that GST is paid only on the profit margin for second-hand goods (like used phones, laptops, or jewelry etc.,). However, this specific rule is strictly restricted to taxpayers who are in the business of buying and selling second-hand goods. w.e.f. 01-07-2017
Notification No. 8/2018-CT (R) (The Motor Vehicle Exception): Introduced in January 2018, this notification acts as a special carve-out specifically for old and used motor vehicles. It allows any registered person (such as an IT firm, a manufacturing company, or a consulting agency) selling a used specified vehicles to pay GST only on the margin, rather than the full transaction value (provided ITC has to been availed)
As per My View - The Advance Ruling is Not Correct... Experts may share their view
