1. Cookies and HMRC

When you use the HM Revenue & Customs (HMRC) website small data files known as cookies are placed on your computer. These cookies are not used to identify you personally, they are used to improve the services you are using by:

  • remembering settings so you don't have to give the same information several times during one task
  • recognising that you may have already entered a username and password so you don't need to do it for every webpage requested
  • measuring how many people are using services, so that HMRC can make sure that there is enough capacity so that the services work efficiently
  • analysing how you use the service so that we can make sure that it meets your needs
