Query on SGB interest credit

I applied for SGB through IDFC bank giving my 5paisa demat details. Demat is linked to Axis account. So will I get interest in idfc or axis?

Interest will be credited in the bank account linked with your demat. So, Axis bank.

Interest is taxable per govt rules

Interest payment is created to the bank account which is linked to your trading/ demat account. In your case, Axis.
