The QRMP scheme (Quarterly Return filing and Monthly Payment) lets businesses with annual turnover up to ₹5 crore file GSTR-1 and GSTR-3B once a quarter while paying tax monthly by challan. It cuts return filings sharply, and its Invoice Furnishing Facility (IFF) lets you upload B2B invoices monthly so your buyers still get their input tax credit without waiting for the quarter to end.
In the first two months of a quarter you pay tax through challan PMT-06 — either 35% of the previous quarter's cash payment (the fixed-sum route) or your actual self-assessed liability. You can optionally upload B2B invoices through the IFF by the 13th of the next month. At quarter-end you file GSTR-1 and GSTR-3B for the whole quarter, with the 3B due on the 22nd or 24th depending on your state.
For an owner, the decision hinges on customers. If you sell B2B, use the IFF every month — otherwise your buyers see your invoices in their GSTR-2B only after the quarter closes, and delayed credit strains the relationship. If you're mostly B2C, QRMP is nearly pure win: fewer filings, same tax, and the fixed-sum challan makes months one and two mechanical.
The common misreading is thinking quarterly returns means quarterly cash outflow. The monthly payment obligation stands, and skipping PMT-06 accrues interest even though no return was due that month. Also note that IMS invoice actions and GSTR-2B reconciliation remain monthly habits regardless of your return frequency.
