How Much Emergency Tax Will I Pay on £1,000? 

There is no single amount of emergency tax that applies to every £1,000 payment.

The deduction depends on the tax code being used, whether £1,000 is weekly or monthly income, and whether the payment comes from employment or a pension.

For the 2026/27 tax year, the standard Personal Allowance remains £12,570. When 1257L is operated on a Week 1 or Month 1 basis, payroll looks only at the current pay period instead of performing the usual year-to-date calculation.

That can produce very different results from codes such as BR or 0T, particularly when the same £1,000 amount is paid over different periods.

What PAYE Factors Determine the Tax Deducted From £1,000?

The tax deducted from a £1,000 payment depends on several PAYE instructions rather than the payment amount alone.

For 2026/27, the standard Personal Allowance remains £12,570, giving PAYE starting points of approximately £242 per week and £1,048 per month. However, whether those amounts are available depends on the tax code being operated.

The main factors affecting a £1,000 payment are:

• Pay frequency: Weekly and monthly payroll use different portions of the annual tax bands.
• Personal Allowance: Codes such as 1257L can provide an allowance, while BR and 0T do not apply the standard allowance to that income in the same way.
• Cumulative status: M1 and W1 prevent payroll from using earlier pay and tax figures.
• Type of income: Employment pay and flexible pension withdrawals can be treated differently.
• Tax jurisdiction: Scottish taxpayers use different Income Tax rates and bands.

The resulting deductions can therefore look like this:

HMRC uses markers including M1, W1, X and NONCUM to show that PAYE is being operated on a non-cumulative basis.

This means payroll focuses on the current pay period rather than recalculating tax using earnings and deductions from earlier in the tax year.

Understanding how an emergency tax code works helps identify which PAYE rules are being applied before comparing the actual deduction with the expected amount.

Official figures can be checked through the 2026/27 PAYE rates and thresholds.

How Does 1257L M1 Tax a £1,000 Monthly Payment?

If £1,000 is one month’s pay and 1257L M1 is being used, the Income Tax deduction would normally be £0.

For 2026/27:

• Monthly PAYE starting point: approximately £1,048
• Monthly payment: £1,000
• Amount above the starting point: £0
• Approximate Income Tax: £0

The Month 1 Basis

The important feature is not just the £1,048 allowance. It is how M1 treats that allowance.

A normal cumulative tax code considers earlier earnings and tax paid during the tax year.

M1 does not.

Suppose someone was unemployed for several months before beginning a new job. A cumulative code may be able to recognise unused allowance from those earlier months.

With M1, the current month is calculated independently.

That is why the 1257L M1 tax code can produce a different PAYE result from ordinary cumulative 1257L even though both are connected to the same standard Personal Allowance.

What Happens If £1,000 Is Weekly Pay on 1257L W1?

A £1,000 weekly payment produces a very different result because the weekly tax-free amount is much smaller.

The 2026/27 weekly PAYE starting point is approximately £242.

So:

£1,000 − £242 = £758 taxable

For a Week 1 calculation, approximately £725 of taxable income remains within the weekly equivalent of the basic-rate band.

The calculation is therefore approximately:

£725 × 20% = £145

The remaining £33 falls into the higher-rate band:

£33 × 40% = £13.20

Total estimated Income Tax:

£145 + £13.20 = £158.20

This is why simply calculating 20% of £758 would not give the complete result.

The 1257L W1 tax code applies the same non-cumulative principle as M1, but it works with one week’s allowance and tax bands instead of one month’s.

How Do BR and 0T Affect a £1,000 Payment?

BR and 0T can both produce approximately £200 of Income Tax on £1,000 of monthly pay, but they reach that result in different ways.

BR Treatment

BR means income from that particular employment or pension is taxed at the basic rate.

For a £1,000 payment:

£1,000 × 20% = £200

BR can be perfectly legitimate on a second job or pension where the taxpayer’s Personal Allowance is already being used elsewhere.

It is therefore important to understand whether BR is an emergency tax code rather than assuming that BR automatically indicates a payroll problem.

0T Treatment

0T provides no Personal Allowance, but unlike BR it still uses the normal tax bands.

On £1,000 of monthly income, the whole payment remains within the basic-rate portion of the monthly calculation, producing approximately £200 of Income Tax.

The distinction becomes more important on larger payments because 0T can move income through higher and additional tax bands, whereas BR itself applies the basic rate to income from that source.

Why Might You Be Put on Emergency Tax?

Emergency tax commonly appears when an employer or pension provider does not yet have enough information to operate the correct cumulative tax code.

Situations can include:

1. Starting a job without giving the employer a P45.
2. Beginning work while information from a previous employer is still being processed.
3. Completing starter information incorrectly or incompletely.
4. Returning to employment after a break.
5. Starting to receive pension income.
6. Taking a first flexible pension withdrawal where the provider does not yet hold an appropriate tax code.

An emergency code is therefore often an information or timing issue, rather than an indication that HMRC is charging a special penalty.

The official emergency tax code rules explain how W1, M1 and X operate.

How Is a £1,000 Pension Withdrawal Taxed on an Emergency Code?

Pension withdrawals need to be considered separately because the taxable proportion depends on the type of withdrawal.

Drawdown and UFPLS

A simplified comparison looks like this:

With a taxable drawdown payment of £1,000, the amount remains below the standard £1,048 monthly starting point.

With a UFPLS, 25% is normally tax-free.

On £1,000:

• Tax-free portion: £250
• Taxable portion: £750
• Approximate Income Tax under the standard Month 1 allowance: £0

The exact outcome can change according to the code held by the pension provider, earlier pension payments and the type of withdrawal being made.

Why Can Larger Pension Withdrawals Face Much More Emergency Tax?

Emergency taxation becomes more significant when someone takes a large one-off pension withdrawal.

A Month 1 calculation does not initially know that the payment is necessarily a one-off amount.

Instead, it applies only one month’s allowance and one month’s tax bands.

A sufficiently large taxable withdrawal can therefore enter the:

• Basic-rate band
• Higher-rate band
• Additional-rate band

This can create a substantial temporary overpayment even where the person’s final annual tax liability is lower.

Retirement analysts have criticised this feature of pension PAYE because savers may have to reclaim money that was over-deducted from a one-off withdrawal.

The important practical point is that the pension provider must normally operate the PAYE code available when the payment is made.

How Can You Fix Emergency Tax After Starting a New Job?

First establish why the emergency code appeared.

If you received a P45 from your previous employment, make sure your new employer has it.

If you do not have a P45, provide the required starter information so payroll can report your circumstances correctly.

HMRC states that tax-code information after starting a new job can take up to 35 days from the employment start date to update once the relevant information has been processed.

If the emergency code remains after your records should have been updated, check:

• Your current employer details
• Previous employment records
• Estimated annual pay
• Current tax code
• P45 information
• Starter declaration

Your employer cannot simply choose to replace an HMRC tax code because you ask them to. Payroll normally has to use the authorised code until updated instructions are received.

Will You Automatically Get Emergency Tax Back?

Sometimes.

If HMRC replaces an emergency code with the correct cumulative code during the tax year, payroll may automatically recalculate the PAYE position.

Where too much tax has been deducted, this can result in a refund being included in a later wage payment.

However, repayment is not automatic in every case.

The outcome can depend on:

• Whether you remain with the employer.
• Whether HMRC has complete information.
• Whether the replacement code is cumulative.
• Whether the tax year has ended.
• Whether the overpayment came from employment or a pension.

If PAYE appears to have been over-deducted, it may also be worth checking whether HMRC owes you a tax rebate.

How Can You Reclaim Emergency Tax From a Pension?

People who have overpaid tax on a flexible pension withdrawal do not always need to wait until the tax year ends.

Different repayment routes can apply depending on what happened to the pension pot.

Common HMRC routes include:

• P55 – generally where part of the pension pot was withdrawn and money remains in it.
• P53Z – generally where the whole pot was taken and the person continues to receive other taxable income.
• P50Z – generally where the whole pot was taken and the individual has stopped working, subject to the applicable conditions.

Using the correct route matters because an incorrect claim can delay repayment.

The official pension tax refund service helps identify the appropriate option.

Does Emergency Tax Also Change National Insurance?

No. An emergency PAYE code controls Income Tax, not National Insurance.

The two deductions use separate rules.

Someone receiving £1,000 could therefore have no Income Tax deducted under 1257L M1 but still see other deductions on the payslip.

These may include:

• National Insurance
• Workplace pension contributions
• Student loan deductions
• Postgraduate loan repayments
• Salary-sacrifice deductions

Therefore, £0 emergency Income Tax does not necessarily mean £1,000 net pay.

Does Scotland Calculate Emergency Tax Differently?

Scottish taxpayers use different Income Tax rates and bands.

For 2026/27, Scotland has several rates ranging from the starter rate through to the top rate.

Scottish PAYE tax codes normally carry an S prefix.

A £1,000 monthly payment benefiting from the standard monthly allowance may still have no Income Tax due, but larger weekly, monthly or pension payments can produce different results because Scottish tax bands differ from those applying elsewhere in the UK.

The location of the taxpayer should therefore be considered when estimating emergency tax on larger amounts.

What Should You Check If £1,000 Has Been Emergency Taxed?

Before assuming the deduction is incorrect, review the information on the payslip or pension statement.

Check:

• The exact tax code.
• Whether £1,000 represents weekly or monthly income.
• Whether M1, W1, X or NONCUM appears.
• Whether BR or 0T is being used.
• Whether a P45 was provided.
• Whether starter information was completed correctly.
• Whether an old employment still appears on your HMRC record.
• Whether the payment came from a pension.
• Whether other payments were made in the same pay period.

The tax code and pay period usually explain far more than the phrase “emergency tax” on its own.

Conclusion

Emergency tax on £1,000 depends on the code, pay frequency and type of payment. A £1,000 monthly payment on 1257L M1 will normally have no Income Tax deducted, while £1,000 weekly on 1257L W1 can produce about £158.20.

BR or monthly 0T can result in about £200. If the deduction looks wrong, check the code on your payslip, confirm your P45 or starter information, and make sure HMRC holds accurate employment or pension details.

FAQs

Is emergency tax always 20%?

No. Emergency tax is not one fixed percentage. The amount depends on the code, pay period, available allowance and tax bands applying to the payment.

Will I pay emergency tax on £1,000 a month?

On the standard 1257L M1 emergency code, £1,000 monthly pay would normally fall below the £1,048 monthly PAYE starting point, so no Income Tax would usually be due.

Why was £200 deducted from my £1,000 pay?

A £200 deduction may indicate that BR or a code such as 0T has been used, because £1,000 taxed at the 20% basic rate produces £200.

Is 1257L automatically an emergency tax code?

No. 1257L by itself is commonly a standard tax code. Emergency treatment is normally indicated when a marker such as M1, W1 or X is attached.

Can my employer refund emergency tax?

If HMRC supplies a corrected cumulative code while you are still employed, payroll may automatically repay an earlier PAYE overpayment through a later payslip.

How long can an emergency tax code stay on my payslip?

It depends on how quickly HMRC receives and processes the information needed to determine the correct code. New-job updates can take up to 35 days in some circumstances.

Can I be emergency taxed on a pension withdrawal of £1,000?

Yes, a first or flexible pension payment can be processed on an emergency basis. However, a £1,000 payment may still result in little or no Income Tax where the standard Month 1 allowance covers the taxable amount.

Does emergency tax mean I have permanently lost the money?

No. If too much PAYE has been deducted, it can potentially be repaid through payroll, an HMRC reconciliation or an appropriate refund claim.
