Information used to work out the amounts you submitted on the end-of-year forms (e.g. P11D and P11D(b)).
Payments that any of your employees contribute towards an expense or an employment related benefit in kind (BIK).
Note: You should always keep a record of any correspondence that you have with HM Revenue and Customs (HMRC).
Error-free record keeping is an important part of providing expenses and benefits to employees. The data needs to be correct and show that you 'accurately' reported your end-of-year forms.
You will need to keep them on file and available for three (3) years from the end of the tax year that they relate to.
Suppose you reimburse the travel expenses for one of your employees. You would need to keep records of when it took place and why the employee needed to travel. Always try to get receipts to show to HM Revenue and Customs as evidence (if needed).
HMRC can ask to see evidence of your accounting for each expense or benefit at the end of the tax year.
