Payments from Roth IRA & IRA

When I moved to the UK I had a Roth IRA and a Traditional IRA in the US I have just closed both of these and taken the money out in full - which I think is a lump sum distribution Are these taxable in the UK? If so, can I take a tax credit in the UK for the US tax already paid?

Hi,

You can. You declare this on Self-Assessment and can include the tax already paid.

Thank you.
