I work for a small company and last year when I was given my christmas bonus, tax came off it, so I didn't actually get what my bonus was. No problems there, but this year I am getting the same amount and my boss said he would tell the accountant the amount I was getting as bonus and then pay me whatever extra the tax would be so that after it's taken off I would actually end up with the bonus amount.
I won't say how much the bonus is, but it was not more than £5000 and my boss is now saying that he will have to pay 31% of that to cover the 31% tax that will be taken off. Now I'm very confused why I would be taxed 31% as I'm a basic rate tax payer (20% right?) and my bonus would nowhere near take me into the next tax threshold (40% at £37,000) so where does this 31% come from? Surely it should be 20%?
