OnePlus is facing a ₹93 crore tax demand from GST authorities concerning its lifetime screen replacement warranty for the 'Green Line Worry Free Solution'. The company has deposited ₹10 crore under protest and believes it has a strong defense against the demand, citing confidence in a favorable outcome. This issue arises as OnePlus's sales and profits reportedly declined in the last fiscal year, with additional tax notices totaling ₹280 crore also received.
