What we do not do

We do not file your refund application or sign RFD-01. You, or your CA, upload the files and file on the GST portal. We never ask for your GST password or an OTP. If you are stuck, write to support@fastgstrefund.com and we reply by email. There is no charge for asking; if you want us to do work for you, we quote a price first.

The generator checks that a file can be created and that its entries are well formed. It cannot tell whether an invoice is in your returns or whether a credit is eligible. Review those with your CA before you file.
