Is GST billing mandatory below the ₹40 lakh turnover threshold? Many small businesses have this common question: "If my turnover is below ₹40 lakh, do I still need to create GST bills?"
The answer depends on whether the business is registered under GST or not.
If a business is not required to register under GST and has not taken GST registration, it generally cannot issue a GST tax invoice or charge GST from customers. However, it may issue a normal bill or invoice for business records.
If a business has voluntarily taken GST registration or is already registered under GST, then GST invoicing rules apply, and the business needs to issue GST-compliant invoices even if its turnover is below ₹40 lakh.
Vinimay Accounting Software helps businesses manage GST and non-GST billing workflows by maintaining invoices, customer records, payments, and accounting information in an organized way.
What Is the ₹40 Lakh GST Turnover Threshold?
Under GST, certain small businesses are eligible for exemption from mandatory GST registration if their annual turnover is below the applicable threshold limit.
For many goods suppliers, the commonly discussed threshold is ₹40 lakh annual turnover, but the actual limit can vary depending on factors such as:
State/Union Territory
Type of business
Nature of supply
Applicable GST rules
Service providers generally have different threshold limits.
Therefore, businesses should check the GST registration requirement applicable to their specific situation.
