Frequently asked questions

When is GST registration mandatory?

Registration is required once aggregate turnover exceeds ₹40 lakh for goods (₹20 lakh in special category states) or ₹20 lakh for services, and irrespective of turnover for inter-state supply of goods, e-commerce sellers, persons liable under reverse charge, non-resident taxable persons and a few other categories. Voluntary registration is also possible and is often useful for B2B businesses that want to pass on input credit.

Can I still claim input tax credit if my vendor has not filed GSTR-1?

Under section 16(2)(aa) and Rule 36(4), ITC can be claimed only to the extent it appears in your GSTR-2B. If your vendor has not uploaded the invoice, the credit is not available in that period. We track these cases monthly and follow up with vendors so that credit is not permanently lost.

What is the Invoice Management System (IMS)?

IMS is a facility on the GST portal that lets recipients accept, reject or keep pending each invoice uploaded by their suppliers before GSTR-2B is generated. Acting on IMS every month gives you control over which invoices flow into your ITC and creates a record of rejected or disputed invoices.

Is the annual return compulsory for every business?

GSTR-9 is mandatory for registered persons with aggregate turnover above ₹2 crore in the financial year, and GSTR-9C is required above ₹5 crore. Businesses below these thresholds are exempt from filing GSTR-9 for the relevant years as per the exemption notifications, though we still recommend an annual reconciliation.

How long does a GST refund take?

For exports and inverted duty refunds, a provisional refund of 90% is generally sanctioned within seven days of acknowledgement of a complete application and the balance after scrutiny, with the statutory outer limit being 60 days. In practice the timeline depends on the quality of the application, which is why we prepare the statements and supporting documents carefully before filing RFD-01.
