Exit from composition scheme

If the threahlod limit of composition exceeds then you need to file an intimation for withdrawal from the scheme in the FORM GST CMP-04 within 7 days of occurrence of the event.
After opting out of the scheme, you can pay tax as normal tax payer and issue tax invoice for every taxable supply made thereafter.
Subsequently you will also be required to file a statement in FORM GST ITC-01 within 30 days from the date of withdrawal from the scheme by giving details of the inputs held in stock on the date on which the option is withdrawn. The said statement has to be submitted on the portal within 30 days from the date of withdrawal.
Then you will be entitled to take credit of input held in stock.
further u would be required to pay GST as per normal rates on the limits over the composition scheme.

Thank u😊
