The QRMP Scheme — Should You Opt In?
The Quarterly Return Monthly Payment (QRMP) scheme allows small taxpayers (turnover up to ₹5 crore) to file GSTR-1 and GSTR-3B quarterly instead of monthly, while paying tax monthly using a simplified challan (PMT-06). This reduces compliance burden without increasing tax payment delays.
What happens if I miss the GSTR-1 deadline?
Late fees apply and your customers cannot claim ITC on purchases from you until you file. This can seriously damage your business relationships, especially with larger buyers who rely on ITC.
Can I file a nil return if I had no transactions?
Yes, and you must! Even if you have zero sales or purchases in a period, you still need to file nil returns by the due date. The late fee for nil returns is lower (₹20/day) but still applies.
How do I know if I'm a monthly or quarterly filer?
If your previous year's aggregate turnover exceeded ₹5 crore, you must file monthly. Below ₹5 crore, you can opt for the quarterly QRMP scheme. If you're new, you file monthly until you complete a full year of registration.
