The Goods and Services Tax (GST) collection for the month of October came in at Rs 1.51 lakh crore, marking the second highest monthly collection after the domestic revenue collections registered in April this year, the Ministry of Finance said in a statement. The October collections continue to maintain the streak for three quarters now when the GST revenue has been above the Rs 1.4 lakh crore mark. The upward trend in the GST collections is pegged to an improved business activity and the recently-culminated festive season.
