Summary: I want to put some capital gains money into a Monzo Pot with 4.60% AER (Baring in mind I have already paid capital gains tax on that money). Do I then have to pay Tax on the interest I will gain. Do I need to fill out a self assesment or does Monzo report my savings to HMRC and tax get reduced from my PAYE?
Sorry if this is a really silly question but remember theres only such thing as silly answers so be nice to me. I am new to savings and this is the first time I have ever had the thought of actually saving so I am hoping I keep it up
