BR Tax Code: Meaning, Checks and Refunds

BR stands for Basic Rate. A payslip carrying the code BR means that all earnings from that employment are taxed at the basic rate of 20%, with no personal allowance applied. There is no number before the letters because no tax-free amount is being given — every pound of gross pay has 20p of income tax deducted before you receive the rest.

It is important to understand that BR does not mean something has gone wrong in itself — it is a legitimate code with specific legitimate uses. The problem only arises when it appears on the wrong job. If BR appears unexpectedly on your main job, check where HMRC has allocated your allowance and whether other income or adjustments explain the code. Main-job status alone does not prove an error.

BR also does not trigger National Insurance changes. NI is calculated separately on each employment and is not affected by the income tax code. So even with BR applied, NI will still be deducted at the normal employee rates on earnings above the Primary Threshold.

BR is the right code in several common situations:

• Second or subsequent job: You can only receive your personal allowance once. If your main job already applies the full 1257L allowance, your second employer should use BR (assuming your second-job income falls within the basic-rate band). This is the most common legitimate use of BR.
• Pension income alongside employment: If you receive a private pension and are also employed, HMRC may allocate your personal allowance to the pension and instruct your employer to use BR, or vice versa. Which source gets the allowance depends on which is larger and on your personal preferences as registered with HMRC.
• First payslip at a new job (no P45): If you started a new job and indicated on your starter declaration that you have another job at the same time, your new employer will apply BR until HMRC issues a formal instruction. This may be correct and will update automatically once HMRC processes the new employment record.
• Temporary code while HMRC processes new information: During periods of uncertainty — for example, if you have left one job and started another but HMRC has not yet confirmed the split of your allowance — a temporary BR may be applied. Check the employment record and follow HMRC’s new-job guidance if the code remains wrong after 35 days.

BR becomes a problem when it appears in circumstances where you should be receiving your personal allowance. The most common errors are:

• Main and only job: If you have just one employer and your payslip shows BR, your personal allowance is being completely ignored. This typically happens because your previous employer did not issue a P45, or because the P45 was not passed to the new payroll team before the first pay run. In some cases it happens when HMRC's systems flag an apparent second employment that has already ended.
• Not updated after leaving previous job: If you had two jobs and left the main one, your remaining employer may still have BR on file from the period when both jobs were active. HMRC should issue a new code, but there can be a lag.
• Payroll never received the correct instruction: Sometimes HMRC issues a revised code but it is not actioned by payroll before the pay run. In this case the error is administrative rather than a genuine HMRC mistake.
• Starter declaration error: If you ticked the wrong box on the starter form — indicating you have another current job when you do not — BR will be applied in error until the position is corrected.

The financial impact of BR on a single-job salary of £25,000 per year is substantial.

An employee on £25,000 would lose £209.50 per month — or £2,514 per year — by having BR applied instead of 1257L. This comparison assumes England in 2026/27, full standard allowance entitlement at this employment, steady pay and no other adjustments. It is not a refund quote: other income, earlier deductions and the code basis determine whether tax was actually overpaid. See the 1257L versus BR comparison for the same-pay calculation.

If BR was wrong for that employment, the extra PAYE is usually corrected in one of two ways.

During the same tax year: HMRC sends your employer the correct code, for example 1257L. If the code is cumulative, payroll recalculates the tax due for the year to date and the over-deduction normally comes back through a later payslip.

After the tax year ends: HMRC reconciles your PAYE record and may issue a P800 calculation or repayment route if the year closed before payroll corrected it.

The detail to check is whether the new code is cumulative or still marked W1, M1, or X. A cumulative 1257L code can catch up automatically. A month-1 or week-1 code may stop a full catch-up in that pay run, even if the headline code now looks right.

Three codes are commonly confused because all three can result in higher-than-expected tax deductions. The table below clarifies the differences.

The distinction between BR and 0T is subtle but important. BR always applies a flat 20% regardless of how high earnings go. 0T applies the normal progressive bands (20%, 40%, 45%) but without any personal allowance first. For earnings entirely within the basic-rate band, BR and 0T produce the same result. For higher earners, 0T results in more tax because the higher-rate and additional-rate bands apply in full.

Compare the payslip code with HMRC's coding notice, then check all employment, pension and income records in your personal tax account. Ask payroll to correct a transcription or starter-processing error; ask HMRC to review an issued code that does not fit your circumstances.

If a corrected cumulative code and complete pay and tax records reach payroll, it can recalculate the year-to-date tax. A W1/M1 correction does not automatically refund earlier deductions. Ask payroll which pay run will include the notice.

After the year ends, HMRC may send a P800; tax calculation letters are sent between June and March of the following tax year. Self Assessment repayments follow that account instead. An overpayment must be established from the complete record, and there is no guaranteed next-payday refund. See the refund routes.

Scottish taxpayers with a second job or a secondary income source will see SBR on the relevant payslip rather than plain BR. The S prefix tells payroll to apply the Scottish income tax rules.

For a second job that falls within the Scottish basic-rate band, the practical effect of SBR is the same as BR for the rest of the UK: a flat 20% applied to all earnings from that employment with no personal allowance. This is because the Scottish basic rate is 20% for 2026–27, matching the UK-wide basic rate.

The difference between Scottish and rest-of-UK codes becomes more significant at higher income levels. If a Scottish taxpayer's combined income from both jobs takes them into the intermediate band (21%) or higher (42%), HMRC will assess their overall tax position through Self Assessment or the coding process and may adjust the code on one or both employments accordingly.

If you are a Scottish taxpayer and BR (without the S prefix) appears on your payslip, contact HMRC to ensure your address is correctly recorded and that the Scottish rates are being applied to your income.
