<h1>September GST mop-up rises 9.1% to Rs 1.89 lakh crore; net GST up 5% to Rs 1.60 lakh</h1> GST mop-up for September rose to Rs 1.89 lakh crore, up 9.1% year-on-year and about 1.5% month-on-month, with net GST at Rs 1.60 lakh crore (5% YoY growth). The increase partly reflects GST rate rationalisation implemented from September 22 affecting 375 items and boosting consumption late in the month; gross domestic tax revenue grew 6.8% to Rs 1.36 lakh crore and import tax rose 15.6% to Rs 52,492 crore. GST refunds surged 40.1% YoY to Rs 28,657 crore. Industry analysts said pre-cut demand and late-month consumption broadly offset each other, though manufacturing state shipments were disrupted by pre-cut ITC concerns.
