under QRMP ,is it necessary to file PMT-06 (on self assessment basis ) challan every month ?
because as far as my information there is no late fees for filing it ,does it mean that for example for Quater April - June instead of filing PMT-06 challan every month I can file a single challan before 18th July before filing GSTR3B of quater and no late fees or penalty will be imposed on me?
