This discussion addresses the challenge faced by traders when the GST rate increases, but the MRP on existing stock remains unchanged. When the GST rate rose from 12% to 18%, traders found themselves unable to pass the additional tax burden to customers due to the fixed MRP. This situation forces traders to absorb the extra cost, impacting their profit margins. Various solutions were explored, including marking up prices, offering discounts, and potentially using revised MRP stickers, though the legality and practicality of some methods were debated.
