20 lakh turnover limit is to take the registration, once you obtain the registration you need to pay the GST even if your turnover is less than 20 lakh in a FY, its not like a service tax.
If your turnover will not 20 lakh in FY you can apply for cancellation of GST registration, once your registration is cancelled then you are not required to pay GST.
