New Delhi, Oct 1 (PTI) Gross GST collection rose 9.1 per cent to over Rs 1.89 lakh crore in September on the back of increased sales due to rate rationalisation, as per government data released on Wednesday.

Gross Goods and Services Tax (GST) mop-up was Rs 1.73 lakh crore in September 2024. Last month, the collection was Rs 1.86 lakh crore.

The gross domestic revenue grew 6.8 per cent to Rs 1.36 lakh crore, while tax from imports rose 15.6 per cent to Rs 52,492 crore in September.

However, GST refunds also rose to 40.1 per cent year-on-year to Rs 28,657 crore.

Net GST revenue stood at Rs 1.60 lakh crore in September 2025, recording 5 per cent year-on-year growth.

GST rate rationalisation, which came into force on September 22, has been reflected in the GST numbers.

GST rate rationalisation drives higher gross GST collections and increased refunds, reflecting consumption and import growth. Gross GST receipts rose year on year with net GST revenue recording modest growth, driven by stronger import tax inflows and higher domestic consumption, while GST refunds expanded notably. The changes are attributed to the GST rate rationalisation implemented in late September, which lowered rates across a wide range of goods and services and influenced sales volumes, import receipts, and refund claims, altering the short term revenue composition.
