Have you checked your payslip recently and noticed the tax code ‘BR’? You may have seen a larger tax deduction than expected and wondered why you are paying so much tax.
You’re not alone. Understanding the letters and numbers on your payslip is crucial for managing your finances, but the BR tax code often causes confusion.
The UK’s system for collecting Income Tax from employment and pensions is called Pay As You Earn (PAYE). At its heart, PAYE relies on tax codes issued by HM Revenue & Customs (HMRC) to tell your employer or pension provider how much tax to deduct from your earnings or payments. While many people will be familiar with codes like 1257L, seeing ‘BR’ can be confusing if you don’t know what it means.
In this guide, we’ll explain what the BR tax code means, why you might have it, how it affects your pay, and what to do if it’s wrong.
First Things First: What is a Tax Code Anyway?
Before diving into the specifics of the BR tax code, it’s helpful to understand the role of tax codes within the UK system.
- Purpose: A tax code is an instruction from HMRC to your employer or pension provider. It translates your tax-free Personal Allowance and any adjustments into a code that their payroll software uses to calculate how much Income Tax to deduct each payday.
- Structure: Most codes consist of numbers followed by a letter. The numbers usually represent the tax-free income you’re entitled to in that job or pension, divided by 10. For the 2025/26 tax year, the standard Personal Allowance is £12,570. This means many people will have the tax code 1257L. The ‘L’ signifies entitlement to the standard tax-free Personal Allowance. The £12,570 Personal Allowance is the amount most individuals can earn before they start to pay tax. Your tax code tells your employer how much of this allowance (if any) should be applied to the income they pay you.
There are several other codes, too, each with a specific purpose. Here’s a quick comparison:
| Tax Code | Meaning | Used When… |
|---|---|---|
| 1257L | Standard tax code | You get the full Personal Allowance – £12,570 in 2025/26 |
| BR | Basic Rate | All income is taxed at basic rate (20%), no Personal Allowance applied |
| D0 | Higher Rate | All income is taxed at higher rate (40%) |
| D1 | Additional Rate | All income is taxed at additional rate (45%) |
| K | Negative adjustments | You owe tax from other income or benefits |
| NT | No Tax | No tax deducted from income |
Self-employed individuals aren’t given a tax code. Instead, they receive a Unique Taxpayer Reference (UTR) and must complete a Self Assessment tax return to report their income and pay any tax due.
Decoding the BR Tax Code
The BR tax code stands for ‘Basic Rate’. If you’re on this code, all the income from that job or pension is taxed at the basic rate of 20% (in England, Wales, and Northern Ireland; Scotland has its own rates).
This means you don’t receive any tax-free Personal Allowance on income taxed under the BR code. By contrast, someone on 1257L only starts paying income tax after earning more than £12,570 in the year.
So, if you’re on the BR tax code, your take-home pay may be lower than expected, especially if this is your only income.
Why Might You Have a BR Tax Code? Common Scenarios
Being on a BR tax code isn’t necessarily wrong, but it usually only applies in specific situations. Here are the most common reasons HMRC might issue one for you:
Having a Second Job or Pension
When you have more than one source of income (such as a second job or a pension), your primary job typically uses your Personal Allowance. Any additional income is taxed at the basic rate to ensure you’re not underpaying tax.
Example: You work full-time, earning £30,000, and start a weekend role paying £6,000 a year. Your full-time salary uses up your £12,570 allowance. Your second job is taxed at 20%, hence the BR code.
Starting a New Job (Emergency Tax)
If you’ve started a new job and haven’t given your employer a P45 from your previous employment or haven’t filled out a Starter Checklist, your employer may use a BR code as an emergency tax code.
This temporary measure ensures that at least basic rate tax is deducted until your correct tax code is issued.
Example: You switch jobs mid-year but don’t provide your P45. Your new employer puts you on the BR code until they hear otherwise from HMRC. You may end up overpaying tax temporarily.
Insufficient Information
If HMRC lacks complete or up-to-date information about your employment or income situation, they might issue a BR code as a default until they can clarify your circumstances.
You’re Receiving a State Pension and Other Income
Although State Pensions are typically paid without tax being deducted, any other income, such as a private pension or job, may be placed on BR to make sure the overall tax is correct.
The Impact of a BR Code on Your Pay
Being taxed under the BR code means you lose access to your tax-free Personal Allowance on that income. As a result:
- You’ll pay 20% tax on all earnings from that job or pension.
- Your take-home pay will be reduced compared to someone with a tax-free allowance applied.
- You may be paying too much tax if BR is incorrectly applied, especially if this is your only job.
Example: Sarah earns £1,500 per month in a part-time role and is on BR. She pays 20% tax on all of it (£300/month) despite earning below the £12,570 annual threshold. She’s likely due a tax refund if this is her only job.
How to Check Your Current Tax Code
Knowing what tax code(s) are being used for you is vital. You can find this information in several places:
- Payslip: Your current code is usually shown on each payslip from your employer or pension provider.
- P45: If you leave a job, your P45 shows the tax code used up to your leaving date.
- P60: Your P60 is an annual summary (given after the end of the tax year in April) detailing your total pay and tax deducted for the previous year, including the code used at year-end.
- HMRC Personal Tax Account: This is often the easiest and quickest way. Setting up an online account with HMRC allows you to see your current tax codes for all employments and pensions, check your estimated income, and update details. You can access it via the GOV.UK website.
- HMRC App: Similar to the online account, the HMRC app provides convenient access to your tax information.
- HMRC Correspondence: HMRC may send you a PAYE Coding Notice if your code changes.
Is the BR Code Correct in Your Situation?
Let’s explore some scenarios where the BR tax code is or is not appropriate:
| Scenario | Is BR Likely Correct? | Why? |
|---|---|---|
| This is your second job or pension. | Yes | Your Personal Allowance (£12,570 in 2025/26) is likely allocated to your main income source. |
| You have two jobs (or more). | Yes (for the 2nd/3rd) | As above, the allowance is typically used only once against the primary/highest income source. |
| You just started a new job and haven’t given a P45 / full info. | Maybe (Temporarily) | It might be an emergency tax code applied initially. Should be corrected once HMRC has info. |
| This is your one job or pension. | No | You should normally receive the benefit of your tax-free Personal Allowance against this income. |
| Your circumstances changed (e.g., stopped main job, now only have this one). | No | Your allowance may need reallocating. You need to inform HMRC. |
What To Do If You Think Your BR Tax Code is Wrong
If you suspect your BR code is incorrect, especially if it’s your only job, or you believe your allowance isn’t allocated correctly, you must take action.
Don’t assume your employer can fix it. While you should check your payslip, your employer uses the code HMRC provides them. They cannot usually change it without official instruction from HMRC.
Contact HMRC
Your employer can’t change your tax code themselves. They must follow HMRC’s instructions. You can:
- Use your Personal Tax Account to report changes or check/update job information.
- Call HMRC’s Income Tax Helpline: 0300 200 3300.
- Write to HMRC (though this is slower).
Have the Right Info Ready
When you contact HMRC, you’ll need:
- Your National Insurance number
- Details of your income (jobs, pensions)
- PAYE reference numbers (found on your payslips or P60s)
What Happens Next?
HMRC will assess your situation. They’ll issue a new code to your employer or pension provider if a correction is needed.
If you’ve overpaid tax, you’ll typically receive a refund through your salary in future months. Alternatively, you may be issued a direct tax rebate from HMRC, especially if the correction comes after the tax year ends.
Conclusion
The BR tax code might look small and unassuming on your payslip, but it can significantly impact how much tax you pay.
If you’re on the BR code:
- It means you’re being taxed at the basic rate (20%) on all income from that source.
- It’s common with people having two jobs, pensions, or new employment without the proper documentation.
- It can lead to paying too much tax, but it’s fixable.
Always check your tax code when you start a new job, receive a new pension, or notice unexpected changes in your take-home pay. If in doubt, contact HMRC.
Understanding your tax code helps you stay in control of your finances and ensures you only pay the tax you owe.
