The tax year runs from 6 April to 5 April. In the period 6/04/06 to 06/04/07, you can earn up to £5,035 without paying tax or in your case, £8,965. The balance is then taxed at three rates (but you will only pay tax in the first two): Roughly the first £2,000 is taxed at 10% (£200) The remainder is taxed at 22% ( £1,532.30) Total tax is £1,732.30 Assuming you are an employee and not self employed, you will have to pay class 1 NI Contributions. This is currently 11% (but again, the first £5,035 is free) In other words, you pay £986.15 in NI. Grand total is £2,718.45. I hope you are writing as an employee, not an employer. If you are trying to work out what to tax an employee, you must contact your local HMRC office immediately to register.
