Is BR an Emergency Tax Code? | UK Tax Guide 

Seeing BR on a payslip can be confusing, particularly after starting a new job or taking on an additional source of income. It is sometimes described as an emergency tax code, but BR on its own is not an emergency tax code.

BR means that all income from that particular job or pension is taxed at the basic rate of Income Tax, with no Personal Allowance allocated to that source.

HMRC commonly uses it where someone has more than one job or pension and their Personal Allowance is already being used elsewhere.

For the 2026/27 tax year, the basic Income Tax rate is normally 20% in England, Wales and Northern Ireland. Scotland operates different Income Tax bands and uses Scottish-specific codes such as SBR.

An emergency tax code is different. HMRC identifies emergency treatment through markers such as W1, M1, X or NONCUM.

Therefore, a code such as BR X can operate on an emergency basis, while ordinary BR does not.

Understanding the difference is important because BR can be perfectly correct for a second job but could result in too much or too little tax being deducted if it has been allocated to the wrong income source.

What Does the BR Tax Code Mean?

The letters BR stand for Basic Rate.

When an employer or pension provider uses BR, Income Tax is deducted from all taxable income from that particular employment Is BR Actually an Emergency Tax Codeor pension at the basic rate.

There is no tax-free Personal Allowance applied through that source.

HMRC’s guidance explaining what different tax codes mean confirms that BR is generally used when someone has more than one job or pension.

For example, suppose someone has:

• A main job where their Personal Allowance is being used.
• A second part-time job.
• BR allocated to the second job.

If the employee earns £1,000 in a month from the second job and BR applies at 20%, approximately £200 would be deducted as Income Tax from that income, subject to the normal PAYE calculation.

The important distinction is that BR does not provide a Personal Allowance against that income.

For a more detailed explanation of how deductions are calculated, see this guide to the BR tax code.

Is BR Actually an Emergency Tax Code?

No. BR alone is not an emergency tax code.

This is one of the most important distinctions to understand when reading a PAYE tax code.

HMRC says a taxpayer is on an emergency tax code when the code ends in:

• W1 – Week 1 basis.
• M1 – Month 1 basis.
• X – used where pay dates vary.
• NONCUM – another way some payroll systems describe non-cumulative treatment.

HMRC’s official guidance on emergency tax codes explains that emergency PAYE calculations consider the current week or month rather than using the taxpayer’s complete cumulative income and tax position for the year.

This means there is an important difference between BR and BR X.

The same distinction applies to other PAYE codes. For example, understanding whether 1257L is an emergency tax code helps separate a normal tax code from one carrying an emergency marker such as W1, M1 or X.

Why Might Someone Be Put on a BR Tax Code?

BR is particularly common when a taxpayer has more than one PAYE income source.

HMRC only gives a person one Personal Allowance for each tax year. Having two jobs does not mean receiving two separate £12,570 allowances.

For example, someone might have:

• 1257L on their main job.
• BR on their second job.

The main employment uses the Personal Allowance, while earnings from the second employment are taxed from the first pound at the applicable basic rate.

Other circumstances that can result in BR include:

• Having two jobs at the same time.
• Receiving employment income alongside a pension.
• Receiving more than one pension.
• Starting another job while HMRC still records an earlier employment as active.
• HMRC allocating the Personal Allowance to another PAYE source.
• Employment information not yet being updated correctly.

BR on a Second Job

A BR code is not necessarily a problem when it appears on a second employment.

Consider an employee earning £30,000 from their main job and another £5,000 from a second job.

Their main job might use their Personal Allowance, while BR is allocated to the £5,000 second income.

In that situation, using BR may help collect the appropriate basic-rate tax from the second employment.

However, the final position depends on the person’s total taxable income across all sources.

BR on Your Only Job

More attention may be needed if BR suddenly appears on someone’s only job.

Because BR does not allocate a Personal Allowance, an employee who is entitled to the full allowance could have tax deducted from earnings that would otherwise fall within their tax-free allowance.

Possible causes include incomplete employment records, an old employment remaining active or HMRC believing the taxpayer’s allowance is being used against another source.

If BR appears unexpectedly on a main or only employment, checking whether the tax code is correct can help identify problems with allowances, employment records or estimated income.

How Is BR Different From an Emergency Tax Code?

The main difference is what the code tells payroll to do.

BR determines the rate at which the income from that source is taxed.

An emergency marker such as M1, W1 or X determines how the PAYE calculation is applied across the tax year.

A normal cumulative tax code considers relevant income, allowances and tax already paid from earlier periods in the same tax year.

An emergency or non-cumulative code generally looks only at the current pay period.

Someone can therefore remain legitimately on BR for an extended period if it is the correct code for a secondary source of income.

An emergency code is more commonly associated with circumstances in which HMRC or an employer does not yet have all the information required for the normal cumulative PAYE calculation.

What Does BR X Mean on a Payslip?

BR X is different from ordinary BR.

The BR element still tells payroll to apply the basic rate to income from that source, while the X marker indicates emergency or non-cumulative treatment.

That makes BR X an emergency tax code.

This distinction matters when searching for information about “BR emergency tax”. A payslip containing only BR should not be treated in exactly the same way as one containing BR X.

The BRX tax code combines basic-rate taxation with non-cumulative or emergency treatment, which is why BR X should not be confused with ordinary BR.

Could BR Make Someone Pay Too Much Tax?

Yes, but BR does not automatically mean someone is overpaying tax.

Whether too much tax is being deducted depends on the individual’s complete income and circumstances.

Consider someone who earns £10,000 a year from their only job and is entitled to the standard Personal Allowance.

If BR were incorrectly applied to that employment, tax could be deducted even though the employee’s income may be within their available Personal Allowance.

By comparison, someone earning £35,000 from their main employment and £6,000 from a second job might legitimately have their allowance allocated to the main job and BR applied to the second.

BR can potentially result in the wrong amount of tax where:

• It has been placed on the person’s main or only employment incorrectly.
• HMRC believes another job still exists when it has ended.
• The Personal Allowance has been allocated to the wrong income source.
• Estimated income figures held by HMRC are incorrect.
• A second income pushes total earnings into a higher tax band.
• Employment or pension information has not been updated.

It can also work in the opposite direction. Someone whose combined income means part of their earnings should be taxed at a higher rate could potentially underpay tax if an entire secondary income is taxed only at the basic rate.

This is why the code needs to be considered alongside total annual income rather than judged solely by the letters appearing on a payslip.

How Can Someone Check Whether BR Is Correct?

The first step is to confirm the exact code shown on the payslip.

Check whether it says:

• BR
• BR X
• BR W1
• BR M1
• 1257L
• 1257L W1
• 1257L M1
• Another code entirely

This prevents ordinary BR from being confused with an emergency version.

The taxpayer should then check:

1. Which job is using the Personal Allowance.
2. Whether HMRC records any old employment as still active.
3. Whether estimated employment or pension income is accurate.
4. Whether taxable benefits are included correctly.
5. Whether income from another job or pension explains the BR code.
6. Whether the code recorded by HMRC matches the one being operated by payroll.

It is particularly useful to investigate when BR appears unexpectedly after changing jobs or when take-home pay changes significantly.

Employees who have recently changed jobs or whose PAYE information is incomplete may also find it useful to understand how an emergency tax code works and why it can temporarily affect take-home pay.

How Can a BR Tax Code Be Changed If It Is Wrong?

An employer normally cannot simply choose a more favourable tax code because an employee believes BR is incorrect.

HMRC determines the tax code that an employer or pension provider should operate.

If BR appears to be wrong, HMRC recommends checking and updating the information it holds.

Its guidance on how to update an incorrect tax code explains that the online Income Tax service can be used to review information including employment, pensions, estimated taxable income, company benefits and expenses.

Useful information to check includes:

• Current and previous employment details.
• Estimated annual pay.
• Pension income.
• Taxable company benefits.
• Employment expenses.
• Jobs that have already ended.
• Other information affecting the Personal Allowance.

A P45 can also be important when changing employment because it gives the new employer details about previous pay and tax.

HMRC says that where a tax code needs changing, it will normally update the code and tell both the taxpayer and employer.

HMRC currently advises that this should happen within 15 working days after the relevant information has been corrected.

Once a new code has been issued, someone paid monthly would normally expect it on their next or following payslip, while a weekly-paid employee should normally see it by their third payslip.

Will Overpaid Tax Be Refunded After BR Is Corrected?

If BR has caused too much Income Tax to be deducted, the position can often be corrected through PAYE once HMRC issues the appropriate tax code.

With a cumulative code, payroll may take account of income and Income Tax already recorded during the tax year and adjust later deductions accordingly.

However, the precise refund process depends on:

• Whether the tax year is still open.
• Whether the employee is still working for the employer.
• Whether HMRC has complete pay and tax records.
• Whether the new code is cumulative or non-cumulative.
• The taxpayer’s other sources of income.

Someone should therefore avoid assuming that every BR deduction automatically creates a refund entitlement. BR may have been correct throughout.

How Does BR Compare With 1257L?

For many taxpayers in England and Northern Ireland, 1257L is the standard code where the full £12,570 Personal Allowance is available through that employment or pension.

BR works very differently.

For 2026/27, 1257L W1, 1257L M1 and 1257L X are examples of emergency tax codes.

Ordinary 1257L is not an emergency code, just as ordinary BR is not an emergency code.

Does BR Affect National Insurance?

BR is an Income Tax code, not a National Insurance category.

Changing from 1257L to BR can change the amount of Income Tax deducted from a payslip, but it does not by itself determine National Insurance contributions.

National Insurance is calculated under separate rules using the employee’s relevant earnings and National Insurance category.

The same distinction applies to other deductions such as:

• Workplace pension contributions.
• Student loan repayments.
• Postgraduate loan repayments.
• Salary sacrifice arrangements.

These should not be assumed to change simply because the PAYE tax code has changed.

What Should Someone Remember About the BR Tax Code?

The most important point is that BR is not an emergency tax code by itself.

BR tells an employer or pension provider to tax all income from that particular source at the basic rate without allocating a Personal Allowance to it.

It is frequently appropriate for a second job or pension where the taxpayer’s Personal Allowance is already being used elsewhere.

Emergency PAYE treatment is identified separately by markers such as W1, M1, X or NONCUM.

Therefore:

• BR – not automatically an emergency code.
• BR X – emergency/non-cumulative treatment.
• 1257L – not an emergency code by itself.
• 1257L M1 – emergency Month 1 code.
• 1257L W1 – emergency Week 1 code.
• 1257L X – emergency/non-cumulative code.

If BR appears on a second income source, it may be entirely correct.

If it appears unexpectedly on a person’s only job, or the information held by HMRC does not reflect their current circumstances, the tax code should be checked and the underlying employment or income information corrected.

Frequently Asked Questions

Is BR an emergency tax code?

No. BR alone means all income from that job or pension is taxed at the basic rate. Emergency treatment is normally identified by W1, M1, X or NONCUM.

What does BR mean on a payslip?

BR means Basic Rate. No Personal Allowance is allocated to that source, so its income is taxed at the basic rate.

Is BR normal for a second job?

It can be. BR is commonly used where the taxpayer’s Personal Allowance is already allocated to their main employment.

Is BR X an emergency tax code?

Yes. The X marker indicates emergency or non-cumulative PAYE treatment.

Why am I on BR if I only have one job?

HMRC may have incomplete or outdated employment information, or may believe your Personal Allowance is being used against another income source. Check your PAYE record before assuming the code is incorrect.

Will BR tax be refunded?

A refund may be due if BR caused too much Income Tax to be deducted. Whether a refund is owed depends on the taxpayer’s total income, allowances and tax already paid.

Can my employer change BR to 1257L?

An employer should operate the tax code HMRC instructs it to use or the appropriate starter code under PAYE rules. If the code is wrong, the underlying information should generally be corrected with HMRC rather than payroll choosing a different code independently.

How long does HMRC take to change a wrong tax code?

HMRC says that when a tax code needs changing after information is corrected, it will normally update the code and notify the taxpayer and employer within 15 working days.
