Is the pre-registration of credit card necessary in the GSTN portal for the GST payment?

Yes. The taxpayer would be required to pre-register his credit card, from which the tax payment is intended, with the Common Portal maintained on GSTN. GSTN may also attempt to put in a system with banks in getting the credit card verified by taking a confirmation from the credit card service provider. The payments using credit cards can therefore be allowed without any monetary limit to facilitate ease of doing business.
