A BR tax code means you're paying Income Tax at the basic rate of 20% on all earnings from that job.
Unlike the standard 1257L tax code, a BR code doesn't include any tax-free Personal Allowance.
For most taxpayers, the first £12,570 of annual income is tax-free through their Personal Allowance. Under a BR tax code, that allowance isn't applied to that particular income source, meaning every pound earned is taxed at 20%.
The letters simply stand for:
B=Basic R= Rate
Because of this, BR is often referred to as the Basic Rate tax code.
The easiest way to understand a BR tax code is to compare it with the standard tax code most employees use.
Example: Standard tax code (1257L)
If you earn £1,000 per month and you're on a standard 1257L tax code, part of that income is covered by your Personal Allowance before tax is calculated.
Example: BR tax code
If you earn £1,000 per month under a BR tax code, the entire £1,000 is treated as taxable income and taxed at 20%.
That means:
This isn't automatically wrong. It depends entirely on your wider circumstances.
There are several reasons HMRC might apply a BR tax code.
Some are perfectly normal. Others may indicate your tax affairs need updating.
You have more than one job
This is the most common reason.
Most people only get one Personal Allowance each tax year.
If you have:
HMRC will usually apply your Personal Allowance to the job paying you the most.
Any additional jobs may be placed on a BR tax code.
Example
Sarah earns:
HMRC applies her Personal Allowance to the £35,000 role.
The second job receives a BR tax code, meaning earnings from that role are taxed at 20%.
In this situation, the BR code is completely normal.
You've recently changed jobs
When you start a new job, HMRC and your employer need information about your previous earnings and tax paid.
If they don't receive that information immediately, a temporary BR code may be used while records are updated.
This commonly happens when:
If you're drawing a pension and still working, HMRC may apply your Personal Allowance to one source of income and place the other on a BR code.
HMRC doesn't have enough information
Sometimes BR is simply a temporary holding position.
Rather than risk collecting too little tax, HMRC may apply a BR code until they receive accurate information about your circumstances.
Not necessarily.
This is one of the most common misconceptions.
A BR tax code and emergency tax are not the same thing, although they can sometimes appear together.
Emergency tax is usually applied when HMRC doesn't have enough information to issue the correct code.
You may see codes such as:
A BR code can be temporary and may feel similar to emergency tax, but it isn't automatically an emergency tax code.
Not always.
In fact, many people should be on a BR code.
A BR tax code is usually correct if:
However, it may be wrong if:
If your only employment is on a BR code, it's worth investigating.
You can check your current tax code by:
Once you've confirmed you're on BR, ask yourself:
If the answer to all of these questions is "no", it may be worth contacting HMRC.
In many cases, HMRC will update a BR tax code automatically.
This often happens when:
Sometimes, though, you may need to contact HMRC yourself.
You can do this through:
Before contacting HMRC, gather:
The more information you provide, the quicker the correction is likely to be.
Potentially, yes.
An incorrect BR tax code can result in you paying more tax than necessary.
This commonly happens when:
Example
Imagine you worked two jobs last year:
You then left Job 1 and continued only with Job 2.
If HMRC didn't update your tax code, you may have continued paying tax on all your earnings despite being entitled to a Personal Allowance.
That could result in an overpayment and a tax refund being due.
If you're reviewing your tax code, it's also worth checking whether you're receiving all available tax reliefs.
If you're married or in a civil partnership, you may be able to transfer part of your Personal Allowance.

Tax code adjustments
HMRC sometimes builds reliefs directly into your tax code. If these aren't included, you may be paying more tax than necessary.
Tax codes can seem complicated, but they don't have to be.
If you've been placed on a BR tax code and aren't sure whether it's correct, it's worth checking sooner rather than later.
Many people assume HMRC will automatically fix every issue. While updates often happen automatically, mistakes can occur and overpayments can continue for months or even years if nobody spots them.
Checking your tax position now could help ensure you're paying the right amount of tax and identify whether HMRC owes you money back.

BR stands for Basic Rate. It means all earnings from that job are taxed at 20%, with no Personal Allowance applied.
No. It's often completely correct, especially for second jobs and additional pensions.
Not necessarily. BR can be used temporarily, but it isn't automatically an emergency tax code.
Yes, if the code was applied incorrectly and caused you to overpay tax.
Yes. This is one of the most common reasons for a BR tax code.
A 1257L tax code includes your Personal Allowance. A BR tax code taxes all earnings at 20% with no allowance applied.
If it's correct for your circumstances, it may remain indefinitely. If it's being used temporarily, HMRC should update it once they receive the necessary information.
