How do I work out my tax?
If you are an employee, your employer takes income tax and National Insurance contributions (NIC) off your pay before paying you. Your employer sends the tax and NIC to HM Revenue & Customs (HMRC). You need to be able to work out your tax, so that you can check your employer is deducting the right amount of tax from your pay.
The system your employer uses to collect tax and NIC at source is called Pay As You Earn (PAYE). PAYE spreads your tax and NIC over the tax year. The tax collected under PAYE is an estimate, and is not necessarily the exact amount you are required to pay.
Remember that the tax year runs from 6 April one year to 5 April the next, for example, the tax year 2018/19 runs from 6 April 2018 to 5 April 2019.
