FIG and mutual fund gains

I will be moving permanently back to the UK this summer from the US. I have savings and investments that pay interest and dividends into my US bank account. All of my income will be from the US. Do I need to complete a self assessment? Also, if I transfer some of the money from my US bank account to my UK bank account, will this need to be reported?

Hi,
Once you return to the UK, if resident and domiciled, you are liable on your worldwide income so any foreign income would need to be declared in a tax return.
You do nOt need to declare the transfer of the capital to the UK but you do need to report any interest or dividends that this then generates.
Thank you.
