Any change or alteration made in the GST Registration or the details entered in the GST certificate is referred to as GST modification. One may opt for Amendment in GST Registration if he wishes from composite to normal scheme, or if there are mistakes in GST registration. To get GST modification, you need to file form GST REG 14.Since the beginning of GST regime in 2017, the taxpayers could register under 2 schemes- normal scheme and composite scheme. One could also shift from normal to composite scheme. However, the government had declared 31st March 2018 as the deadline to get GST Registration under composite scheme by filing Form GST CMP-02. Now, one can't shift from normal to the composite scheme but can go vice-versa with a GST modification.
