What does a BR tax code mean? If you've got the letters “BR” in your tax code, you're being taxed at the basic rate from the first penny you earn in this job. This might be because your employer doesn't have the information needed to set your code properly, but it's not necessarily wrong.

How do I fix my BR tax code?

If you believe your tax code is wrong you should contact HMRC who will issue your employer with a revised tax code as required. This can be done by phone – 0300 200 3300 – or on-line .

Can I claim back Br tax?

When your code is changed, any overpayment of tax for that tax year is repaid through your salary. If you've had a BR tax code during the last year, or any of the previous four tax years, you could be owed a refund for these years as well.
