Question: how long do i need to keep tax vouchers?
Answer: When it comes to tax-related paperwork like payslips, P45s and so on, HM Revenue and Customs (HMRC) suggests keeping them for at least 22 months from the end of the tax year they relate to. So, as the tax year finishes on April 5, you'll want to keep your relevant paperwork until at least January 31 two years later.
