How to File GSTR-1 for Small Businesses

Small businesses in Delhi can easily file GSTR-1 under the QRMP scheme if turnover remains below ₹5 crore. Monthly filing applies only to larger businesses, making compliance simpler for shops and traders.

GST Compliance Experts offers hassle-free GST return filing services that handle portal navigation, data entry, and timely submission for small enterprises.

Who Files GSTR-1?

All GST-registered regular taxpayers must file GSTR-1, even if their sales are nil (nil return). Composition scheme dealers and TDS deductors are exempt.

Small businesses qualify for quarterly filing under QRMP if the aggregate turnover ≤ ₹5 crore in the previous year.

Filing Frequency for Small Businesses

QRMP filers report B2B invoices monthly via IFF (Invoice Furnishing Facility) for buyer ITC, then file a complete quarterly GSTR-1.
