2. Select ‘Application to Opt for composition Levy’ from the Registration Menu.

Note: If a normal taxpayer had entered HSN of any Goods or Service which is not eligible for Composition Levy while registering for GST and now wants to opt for the composition scheme, below warning message will pop-up. He/She will not be able to proceed further unless the commodity has been removed from the list of commodities.

4. Your GSTIN, Legal Name of Business, Trade Name (if any), Address of Principal Place of Business and Jurisdiction are auto-populated. Select the Category of Registered Person.
Note: Manufacturers who are dealing in Goods restricted for composition are not allowed to select option “Manufacturers, other than manufacturers of such goods as may be notified by the Government for which option is not available”. In case taxpayer selects the said option, then following error message will be displayed on the screen.

5. Select the Composition and Verification Declaration.
