PAYE Refund Request
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). This system is called Pay As You Earn (PAYE).
Usually there are no issue with the running of PAYE, however if you used to work for more than one employer, or you did not work full tax year there are possibility that you have overpaid tax.
