Will HMRC automatically refund overpaid tax?

If HMRC think you have overpaid tax, they will send you a repayment of tax automatically – you do not need to make a claim. If HMRC think you have not paid enough tax, they will write to you explaining that they intend to collect the underpaid tax through your tax code or telling you how you can repay it to them.
