It is important to understand the tax code. The major reason this is essential is to make sure that neither you overpay nor underpay on your PAYE taxes. HMRC assigns many tax codes, but the BR tax code often creates confusion due to its specific implications.

For clarity, it is useful to know that the BR tax code means you are taxed at the basic rate on all your income from that source, without any personal allowance applied. MMBA Accountants, through expert guidance, has assisted many people in navigating these complex concepts.

In this guide, we’ll explain what the BR tax code is, the meaning of the BR cumul tax code, how tax codes work, and their impact on your tax bill.

What Does the BR Tax Code Mean? (with Example)

The CBR tax code, often referred to as an “emergency code,” indicates that all income from this job or pension will be taxed at the basic rate of 20%. It does not include any tax-free personal allowance. This tax code is typically assigned when:

  • You have more than one job or pension. Your personal allowance is applied to your main job, leaving other income fully taxable at the basic rate.

  • Your new employer hasn’t received sufficient information. The BR code may be applied temporarily.

  • Your circumstances change. If you haven’t informed HMRC about changes, the SBR code may be applied until further calculations are made.


Example:
If you earn £25,000 annually from your main job and an additional £10,000 from a second job, the income from your second job would typically be taxed at 20% under the BR tax code.

What is a Tax Code?

A tax code defines how much PAYE (Pay As You Earn) tax your employer or pension provider should deduct from your salary or pension during each pay period. HMRC calculates your tax code based on your income and personal circumstances.

If your circumstances change, such as starting a new job or receiving additional income, HMRC may adjust your tax code to reflect your updated tax-free allowance and taxable income.

Do Self-Employed Individuals Receive a Tax Code?

Self-employed individuals don’t receive a tax code. Instead, they are assigned a UTR (Unique Taxpayer Reference) and submit a Self-Assessment Tax Return. Unlike employed individuals, self-employed people don’t pay tax via PAYE, making the tax code SBR system irrelevant to them.

Where Can You Find Your Tax Code?

You can find your tax code in several places:

  • On your payslip.
  • In letters from HMRC.
  • Online via your HMRC account.
  • On the HMRC mobile app.


If you’re uncertain about your CBR tax code, contact HMRC to make sure you’re paying the correct tax.

How are Tax Codes Structured?

Tax codes consist of letters and numbers. The numbers generally represent your tax-free personal allowance, while the letters explain special circumstances:

BR CodeAll income is taxed at the basic rate (20%).
L CodeYou receive the standard tax-free personal allowance.
K CodeYou owe tax on untaxed income or taxable benefits exceeding your personal allowance.
M/N CodeReflects adjustments for the transfer of personal allowance between spouses or civil partners.
0T CodeNo personal allowance applied.

Understanding Emergency Tax Codes

Emergency codes are temporary tax codes used when HMRC lacks sufficient information about your income. These include:

BR CodeAll income taxed at the basic rate
W1/M1 CodesWeekly or monthly income taxed without accounting for cumulative income.

If you’re assigned an emergency BR tax code, contact HMRC immediately to avoid overpaying tax.

Common Tax Code Scenarios

Common tax code scenarios include:

Multiple Jobs or Pensions

If you have more than one job or pension, your main job usually receives your full personal allowance, while your secondary income is taxed at the basic rate under the BR code.

New Job

When starting a new job, your employer may temporarily assign a BR tax code while waiting for your official tax code from HMRC.

Receiving Additional Income

Additional income from a second job, state pension, or company benefits (e.g., a company car) might push you into a different tax code like BR or K.

Impact of the BR Tax Code

The BR tax code can lead to paying too much income tax if applied incorrectly. For example:

  • You start a new job: If your new employer applies the BR code, you’ll pay tax on all income without a personal allowance.
  • Incorrect Code: If HMRC hasn’t updated your circumstances, you might pay the wrong amount of tax.


Always verify your tax code to ensure it reflects your situation accurately. Overpayments can be reclaimed via a BR tax code refund.

Conditions for BR Tax Code Refund

Understanding how the BR tax code refund works will provide insight into your payslip to ensure that you are not unnecessarily losing any money. BR stands for Basic Rate, meaning all of your income from a certain job or source is being taxed at 20%, with no personal allowance applied.

This is generally used if HMRC does not have complete details of your income-for instance, when one starts a new job, has more than one employer, or starts to receive a pension. Because the BR code doesn’t take into account your personal allowance, it can sometimes lead to overpayment of taxes.

A BR tax code refund is one that occurs when HMRC reviews your earnings and realises you have paid too much. When the right tax code is input, any amount overpaid is either refunded directly to you or adjusted in your next payslip.

Knowing how the SBR or CBR tax code and its refund process work means you can have more control over your finances, pay the precise amount of taxes due, and avoid the unpleasant surprise of an unexpected deduction.

Other Tax Codes You Should Know

  • K Tax Code: Indicates untaxed income or taxable benefits exceeding your personal allowance.
  • SBR: Scotland’s version of the BR tax code, reflecting Scottish tax rates.
  • T Tax Code: Used when allowances are split between income sources, and HMRC needs more data.

  3. Review Your Tax Bill: Compare your expected tax-free allowance and taxable income against your actual tax payments.

Frequently Asked Questions

Is the BR tax code the same as 1257L?

No, they’re different. The BR code taxes all income at the basic rate of 20% with no personal allowance. The 1257L code applies your personal allowance, meaning you don’t pay tax on the first £12,570 earned.

Yes, you can claim back any overpaid tax. You need to contact HMRC or use your Personal Tax Account online. They will look at your income and make a refund directly if your BR tax code resulted in too much being deducted during the year.

The BR tax code stands for “Basic Rate,” meaning you are taxed at a flat rate of 20% on all your income without any personal allowance. It is commonly applied when you have two jobs, your employer hasn’t received your correct tax code from HMRC, or you’ve started a new job. Unlike a cumulative tax code, the BR tax code doesn’t account for any allowances, previous year’s earnings, or other calculations.

You might be on a BR tax code if:

  • You have multiple jobs or pensions, and this is not your main source of income.
  • HMRC has yet to provide your employer with an updated tax code.
  • Your employer doesn’t know your correct code when you start.

In some cases, being on a BR tax code may result in paying too much tax, especially if your partner’s personal allowance hasn’t been accounted for or your first job is taxed at the BR rate. You should check if your BR tax code is appropriate or request a correction from HMRC.

The general rule is that the BR tax code should only apply to secondary income, such as a second job or pension, where your personal allowance has already been applied to your primary income. If you’re paid weekly or monthly, and you notice discrepancies or believe you’re on the wrong code, contact HMRC. They can review your circumstances and ensure your code reflects factors such as cumulative tax code calculations, additional rate taxpayers, and allowances carried over from the previous year.

Yes, you can: in case you think your BR tax code is wrong, you should contact HMRC to review your tax details. When updated, a revised tax code will be issued to your employer, and future payslips will include the correct deductions.

You might be due for a refund. For overpaid amounts under the BR code, HMRC will check a person’s total earnings and total taxes paid, then issue a refund automatically through your employer or directly after the end of the tax year.

HMRC often assigns the BR code to second jobs because your personal allowance is used on your main employment. The BR code ensures all additional income from secondary work is taxed at the basic 20% rate automatically.

You might be on a BR tax code if HMRC hasn’t received full employment details, you’ve started a new job without providing a P45, or you have multiple incomes. It ensures basic-rate tax is deducted correctly.
