Mr A Gupta, It is the same pattern in all states. First you should get an username and a password from your vat office. Click e-filing in the home page of www.dvat.gov.nic.in.Then enter your username and password. The vat return form will open for you. Fill up all details in the respective columns. If you have to pay any tax you have to do it through e-payment(if necessary) or submit a cheque along with a copy of the e-return print or only with the acknowledgement No you got on the print of the return.For making e-payment you have to select one of the authorised banks(mostly PSBs),open an account,if not already having one,apply to the bank,get a username and password and use it...mjk
