Quarterly return monthly payment scheme streamlines GST compliance with quarterly filings, monthly tax payment, and optional invoice furnishing. The QRMP Scheme allows eligible registered persons with aggregate turnover up to five crore rupees to furnish FORM GSTR-3B quarterly while making monthly tax payments for the first two months of each quarter. The option is exercised on the common portal within the prescribed time window and is GSTIN-wise. Quarterly outward supply details are filed in FORM GSTR-1, with an optional Invoice Furnishing Facility for selected invoices, and monthly tax is paid through FORM GST PMT-06 by either the fixed sum method or the self-assessment method. Quarterly filing, interest, and late fee consequences are specified for delayed compliance.
