Can anyone help with a tax on overseas income question please

[Shylo]

I know I need proper advice but am just trying to work out what might happen ..... o work in the U.K. for a US firm and am a U.K. citizen.

As an incentive to stay with the company will have some shares vested to me next year, and my employer will deduct US withholding tax prior to purchasing the shares

So, will I still have to pay U.K. income tax too?

If anyone has any idea how this works I’d be very grateful

Not sure, but I think:
In the UK you would declare your worldwide income.
Any tax you pay in the US would reduce your UK liability.

Eg you pay £7k worth of tax on the shares in the US.

Your UK tax bill is £20k total. You knock £7k off if you are able to provide proof of paying the £7k in the US.

But check with an accountant.

Generally yes, with credit for US tax withheld. If you pay tax at 40% here and the withholding tax is 24% you will just pay the delta of 16% here.

Thanks both, I really appreciate you taking the time to reply ..... not what I was hoping but makes sense :)
