HMRC warning over 21 tax codes on payslip which mean you're owed money

HMRC has issued an urgent tax code warning over 21 codes which mean you may be OWED money. Your tax code is used by your employer or pension provider to work out how much Income Tax to take from your pay or pension. HM Revenue and Customs (HMRC) will tell them which code to use. You can find your tax code by checking your tax code for the current year online - you’ll need to sign in to or create an online account.

You can also find it on the HMRC app, on your payslip, on a ‘Tax Code Notice’ letter from HMRC if you get one. If you check your tax code online or in the HMRC app, you can also find your tax code for previous tax years or sign up for paperless notifications - this means HMRC will email you when your tax code changes.

HMRC may update your tax code if you start a new job, you get taxable state benefits, you start to get income from an additional job or pension, your weekly State Pension amount changes, your employer tells HMRC you have started or stopped getting benefits from your job, you claim Marriage Allowance or you claim expenses that you get tax relief on.
