Didn't realise you had to pay tax on your first dollar in the US. In the UK we don't pay any income tax on the first £12,570. Also, your top rate is only 24%? That seems really low.

Here's our tax brackets for anyone wondering:


0%      £0 - £12,570

20%    £12,571 - £50,270

40%    £50,271 - £150,000

45%    Over £150,000

You only pay on adjusted gross income. There are deductions. 

It is very complicated.
