Dear Sir/M'am
I’ve filed GSTR 3B of Nov’17 on 20th Dec’17 (last date) but by mistake opted for ‘No’ when it asked that if I’ve made any outward supply. the payment box came disabled & I filed the return (thinking that it is disabled because I may have to pay tax quarterly i.e. at the end of Dec’17. now I realised the mistake and want to know how can I pay my tax liabilities for the month of Nov’17. please note that I’ve filed GSTR 3B of Dec & paid my liabilities for Dec month. Please help
