👉 What is an emergency tax code?

An emergency tax code is a temporary tax code that may be used when your employer doesn't have enough information to apply your correct tax code.

The good news is that it doesn't always stay in place permanently.

Why Might You Be Put on an Emergency Tax Code?

You could be placed on an emergency tax code if you:

Start a new job without a P45

Return to work after a break

Start receiving a pension

Have more than one job

HMRC hasn't yet sent your correct tax code

It doesn't necessarily mean you've done anything wrong.

How Does an Emergency Tax Code Affect Your Pay?

Because your employer may not have your full tax information, the amount of Income Tax deducted from your pay could be different from what you'd normally expect.

Some people temporarily pay:

More tax than they should

Less tax than they should

Once HMRC updates your tax code, any adjustments are usually reflected through payroll or handled by HMRC.

How Can You Check Your Tax Code?

You can normally find your tax code on:

Your payslip

Your P60

Your HMRC online account

Letters from HMRC

If you're unsure whether it's correct, it's worth checking with HMRC.

What Should You Do If You Think Your Tax Code Is Wrong?

If you believe you're on the wrong tax code:

Check your payslip

Compare it with your HMRC online account

Contact HMRC if the information appears incorrect

Providing accurate employment details can help HMRC update your records.

Common Questions

Is an emergency tax code permanent?

No.

It's usually temporary until HMRC has enough information to issue the correct tax code.

Will I get any overpaid tax back?

If you've paid too much tax because of a temporary tax code, HMRC will normally correct this once your records are updated.

Can I avoid an emergency tax code?

Providing your new employer with your P45 (if available) and ensuring your employment details are up to date can help reduce the chances of being placed on an emergency tax code.

Final Thoughts

An emergency tax code is often a temporary measure while HMRC gathers the information needed to calculate the correct amount of tax.

If your payslip doesn't look right, checking your tax code early can help prevent confusion and ensure any issues are resolved as quickly as possible.
