You keep
£2,160.00
of your £3,000 bonus after 20% tax and 8% National Insurance.

## Your bonus month

| Item | Bonus month | Normal month |
| --- | --- | --- |
| Pay before tax (gross) | £5,916.67 | £2,916.67 |
| Income Tax | £973.83 | £373.83 |
| National Insurance | £389.53 | £149.53 |
| Take-home pay | £4,553.30 | £2,393.30 |

This is an estimate. Your payslip can be a little different because of how your employer rounds figures or when deductions are taken. We've assumed 2026/27 rates for England, Wales and Northern Ireland, a standard tax code, no pension and no student loan; change these under More options. Your employer may take more tax in the bonus month itself; any extra comes back over the year.

## Why your payslip might differ

Your payslip can be different from this if:

- your tax code isn't 1257L (check the code on your payslip);
- you pay into a pension or repay a student loan (add them under More options);
- you started or changed job this tax year, and you're on an emergency code;
- this month included a bonus or overtime;
- you have more than one job;
- you live in Scotland, where the tax rates are different.
For hours or pay, ask your payroll team. For a tax code, ask HMRC. [Why is my pay different this month?](https://computenow.co.uk/guides/why-is-my-pay-different-this-month/)

## How a bonus is taxed

A bonus is added to your pay in the month it is paid and taxed through PAYE like the rest of your salary.
Within the basic-rate band it loses 20% to tax and 8% to NI. If it takes your yearly pay over £50,270, the part above is taxed at 40% and NI drops to 2%. We show the tax your bonus adds over the whole year, which is what PAYE settles to by the end of the tax year.
