QRMP, IFF and PMT-06: map the quarter before you act

Confirm the portal status first

The Quarterly Return Monthly Payment scheme changes the filing rhythm for eligible registered persons: GSTR-1 and GSTR-3B are furnished quarterly, while tax may need to be deposited for the first two months using a PMT-06 challan. Eligibility, entry or exit conditions, and the filing frequency shown on the portal must all be checked for the relevant quarter. Turnover by itself does not prove that a person is currently under QRMP.

Begin a quarter by recording the GSTIN, quarter, portal filing frequency and applicable State or Union Territory due-date group. Avoid storing GST credentials in a shared checklist. Confirm current notifications and advisories because due dates can be extended for a period or class of taxpayers.

Decide whether IFF helps

The Invoice Furnishing Facility is optional. It lets a QRMP taxpayer furnish eligible B2B invoice and credit/debit-note details for the first and second months of a quarter, within the portal's limits and timeline. It is a facility, not a return. Details furnished through IFF should not be reported again in the quarterly GSTR-1.

IFF can help recipients see eligible documents earlier, but it adds a monthly cut-off and a duplication control. Before using it, reconcile the month's B2B register, validate GSTINs and invoice values, and mark every uploaded document so it is excluded from the quarter-end upload. If IFF is not used, preserve the records for the quarterly GSTR-1 rather than treating them as omitted forever.

Handle the first two months

For month one and month two, determine the deposit under the method available to the taxpayer on the portal. The fixed-sum method and self-assessment method work differently. Generate the challan in Form GST PMT-06 using the reason for monthly payment for quarterly return. PMT-06 is a challan for depositing money into the electronic cash ledger; it is not a filed return and a deposit does not by itself discharge every liability.

Finish the quarter

At quarter end, reconcile all three months, remove IFF duplicates, prepare GSTR-1, review GSTR-3B and use available ledger balances as permitted. Retain the month-wise calculation, challans, ledgers and acknowledgements. Check the current portal for deadlines and relief before calculating interest or late fee. This workflow makes each monthly action traceable without pretending that a quarterly filer has no obligations between quarter ends.
