What Is the BR Tax Code? [Full Meaning and Tax Impact]

Tax code 'BR' means all income from a job is taxed at the basic 20% rate, with no Personal Allowance applied.

If you've spotted 'BR' on your payslip or PAYE coding notice, it could mean you're paying more tax than you should.

Here's everything you need to know about what the BR tax code is, when HMRC uses it, how it affects your pay, and what to do if you think you're being taxed incorrectly.

Key points

• BR is commonly used for second jobs and emergency tax situations 📄
  HMRC often uses BR when your Personal Allowance is already assigned to another job, or when they do not yet have enough information about your circumstances after changing jobs or returning to work.
• An incorrect BR code can reduce your take-home pay ⚠️
  If BR is applied to your only job or your allowance has not been used elsewhere, you could end up paying more tax than necessary until HMRC corrects it or issues a refund.
• You can usually fix a wrong BR code fairly quickly 🔍
  Checking your Personal Tax Account, contacting HMRC, updating payroll details, or completing a starter checklist can help get the correct tax code issued faster.
• ANNA helps you stay on top of your taxes year-round 🤝

What is the BR tax code?

BR stands for Basic Rate. When this code is applied to a source of income, every pound you earn from that source is taxed at the basic rate of Income Tax (currently 20% for the 2026/27 tax year) with no Personal Allowance deducted first.

This usually happens when HMRC believes your tax-free Personal Allowance is being used elsewhere, such as through another job or pension.

When does the BR tax code apply?

Here are the most common reasons you might be placed on the BR tax code:

Second jobs and additional income sources

The most common situation is a second job. HMRC assumes your Personal Allowance is already allocated to your main job, so any additional employment income gets taxed at the basic rate without any tax-free element.

This is usually correct, since you only get one Personal Allowance across all your income, though it also means your second job might feel like it pays less than expected.

Emergency tax situations

BR is also used as an emergency code when HMRC doesn't have enough information about your circumstances.

This can happen when you start a new job without a P45, return to work after a break, or switch between employment and self employment. In these cases, BR is not supposed to be permanent.

Pension income

Some pension providers apply BR to pension payments when they don't have your tax code on file. This often happens when you first start drawing a pension, change providers, or receive pension income alongside employment income.

If you notice BR on your pension and it doesn't seem right, check your Personal Tax Account or contact HMRC to make sure your allowances have been allocated correctly across your income sources.

How BR affects your take-home pay

Because you lose the benefit of your Personal Allowance on that income, the tax impact is more significant than it might initially seem.

Here's how BR affects your take-home pay:

Note that National Insurance contributions are calculated separately and aren't affected by your tax code.

If your Personal Allowance hasn't been used up elsewhere (for example, if you left your previous job and BR wasn't updated), you may end up overpaying tax.

HMRC will usually fix this at the end of the tax year via a P800, but you don't have to wait that long.

How to fix an incorrect BR tax code

If you think BR has been applied incorrectly – for instance, if it's showing on your only job or you've moved jobs and your previous employer's code wasn't carried across – there are steps you can take to fix it.

Here's what to do:

• Check your Personal Tax Account: You can visit gov.uk to see which code HMRC currently holds for each of your income sources.
• Contact HMRC directly: If the code looks wrong, you can reach HMRC at 0300 200 3300. Have your National Insurance number and employer details at hand for identification.
• Speak to your payroll department: Your employer can only apply the code HMRC issues, but they can sometimes request a reassessment or help you submit the right forms.
• Complete a starter checklist: This applies if you've just started a new job and didn't have a P45. Doing this will give HMRC enough information to issue a correct code rather than defaulting to emergency rates.
• Claim a refund if you've overpaid: If the tax year has ended and you paid too much, HMRC may issue a P800 automatically, or you can claim a refund through your Personal Tax Account.

💡 Did you know?

If you have multiple income sources, it can be easy to lose track of how much tax you're paying across PAYE and self employment. ANNA's Auto Accountant helps you keep everything in one place, so you can spot unexpected tax issues sooner and avoid surprises later in the tax year.

What if you should be on BR?

If you have two jobs and your first job already uses your full Personal Allowance, then BR on your second job is correct. In that case, you won't be overpaying; you're just seeing tax applied without a threshold, which is how it's supposed to work.

Where it gets more complex is if your main income is below £12,570, or if you have other allowances (such as the Marriage Allowance or Blind Person's Allowance) that could be split across income sources.

The rules here are specific, so consider speaking to an accountant if you're not sure.
