If you're on the wrong tax code
Using the right tax code helps you to pay the correct amount of tax and student loan repayments (if you have a student loan) throughout the year.
We've identified that you're on the wrong tax code, which means that the correct amount of tax and/or student loan repayments will not be deducted from your salary or wages. We've asked your employer to change your code to reduce the possibility of you getting a large tax bill at the end of the year.
If you disagree with the new tax code
If you believe that the tax code we've asked your employer to use isn't the right one for your circumstances, you can contact us on 0800 377 778. If we agree with you, we'll update our records and you can inform your employer to change your tax code back.
By law we are permitted to ask employers to change an employee's tax code if they're using the wrong one.
