The turnover limit for GST registration in India is a crucial factor for small and growing businesses. If your aggregate turnover crosses the prescribed threshold, you must register for GST and comply with invoicing and return filing requirements. This article covers why this rule matters, who it applies to, the steps to comply, a worked example with realistic figures, common mistakes, and how HelloBooks can help streamline GST compliance.

Why this comes up / what goes wrong

Many small business owners in India keep their books in spreadsheets, Tally, or manual bill books. They often struggle to know when they must register for GST based on their turnover. Missing the registration deadline or failing to register when required can lead to penalties and compliance issues. Understanding the turnover limit and the registration process helps avoid legal trouble and ensures smooth business operations.

Step-by-step

  1. Who it applies to: Any person or business whose aggregate turnover (sum of turnover from all GSTINs under a PAN) exceeds the prescribed threshold must register for GST.
  1. Threshold/Condition: While commonly cited thresholds are ₹40 lakh for goods and ₹20 lakh for services (lower in some special category States), this article does not state these as verified facts. However, a registered person whose aggregate turnover exceeded ₹5 crore in any financial year from 2017-18 onwards must issue e-invoices for B2B supplies from 1 August 2023 (Notification No. 10/2023-Central Tax).
  1. What must be done: Upon crossing the threshold, the business must apply for GST registration on the GST portal, obtain a GSTIN, and start issuing GST-compliant tax invoices containing all particulars as per Rule 46, including supplier and recipient GSTIN, HSN/SAC codes, tax rates, and invoice serial numbers.
  1. When: Registration must be done within 30 days from the date on which the threshold is crossed. Once registered, the business must file GSTR-1 and GSTR-3B returns monthly or quarterly as applicable.
  1. Return filing deadlines: Monthly GSTR-1 is due by the 11th of the following month, and GSTR-3B by the 20th. Under the QRMP scheme, quarterly GSTR-1 is due by the 13th and GSTR-3B by the 22nd or 24th day, depending on the State.

Example (fictional figures)

A Delhi-based goods supplier crosses the turnover limit in the financial year 2023-24 and needs to register for GST by 30 November 2023.

  • Aggregate turnover as on 31 October 2023: ₹42,00,000 (exceeds ₹40 lakh threshold assumed for goods)
  • Date turnover crossed ₹40 lakh: 15 October 2023
  • Deadline for GST registration: 15 October 2023 + 30 days = 14 November 2023
  • Registration applied on 10 November 2023 (within time)
  • GSTIN obtained on 20 November 2023
  • First GSTR-1 filing due for October 2023 by 11 November 2023 (missed as registration was not active yet)
  • First GSTR-1 filing after registration due for November 2023 by 11 December 2023

This example shows the importance of timely registration and compliance with return deadlines.

Common mistakes

  1. Delaying registration after crossing the threshold: Register promptly within 30 days to avoid penalties. Keep track of turnover regularly.
  2. Ignoring turnover from all GSTINs under the same PAN: Aggregate turnover includes all GST registrations under your PAN.
  3. Incorrect or incomplete tax invoices: Ensure invoices contain all details as per Rule 46, including GSTIN, HSN/SAC codes, tax rates, and invoice serial numbers to avoid rejection.
  4. Missing return filing deadlines: Note the monthly or quarterly due dates for GSTR-1 and GSTR-3B to avoid late fees.
  5. Not issuing e-invoices when required: Businesses with turnover exceeding ₹5 crore must issue e-invoices for B2B sales from 1 August 2023.

Use GST invoicing features to create compliant invoices automatically.
