We have to tax all claims the same way under HM Revenue & Custom’s Pay As You Earn rules, regardless of your personal circumstances. If you’re a non-taxpayer or think that too much tax has been deducted, you’ll need to contact HM Revenue & Customs on 0845 3000 627. If they calculate that you’re due a rebate of the tax you’ve paid in the current tax year, they’ll arrange for this to be paid to you at the end of the tax year.
