Two seperate Gateway ID, one for CapitalGainTax and another for Self-Assessment

I have 2 separate Gateway IDs - one for Capital Gain Tax and other for Self-assessment tax. I tried to logon using self-assessment tax ID to file for Capital Gain Tax, and it says it is for Trust, and when I try Login of Capital Gain tax to file self-assessment, it doesnt allow. How do I make sure that I use only ONE Gateway ID ?

Hi,

You need to create a new government gateway account for the Capital Gains as they are not linked.

Report and pay your Capital Gains Tax

Thank you.
