Emergency tax is one of the biggest shocks for foreign workers starting a job in the UK.
People suddenly notice:
- Their pay is much lower than expected
- A large amount of tax is taken
- No clear explanation from payroll
Many think they’ve done something wrong — they haven’t.
This guide explains what emergency tax is in the UK, why foreign workers are often put on it, and how to fix it.
What Is Emergency Tax in the UK?
Emergency tax is a temporary tax code used when HMRC does not yet have enough information about you.
It usually happens when:
- You start your first UK job
- You change jobs
- You don’t have a tax history yet
It is not a penalty and not illegal.
Why Foreign Workers Are Often Put on Emergency Tax
Foreign workers are commonly placed on emergency tax because:
- HMRC has no previous UK employment record
- Payroll doesn’t have your tax details yet
- You’ve just arrived in the UK
- You didn’t submit a starter declaration in time
This is extremely common for new arrivals.
How Emergency Tax Affects Your Pay
When you’re on emergency tax:
- You may not receive your full tax-free allowance
- More tax is deducted than necessary
- Your net pay looks lower than expected
This often causes panic — especially in the first month.
How to Check If You’re on Emergency Tax
Look at your payslip.
Emergency tax codes often include:
- 1257 W1
- 1257 M1
- BR
- 0T
If you see one of these, you’re likely on emergency tax.
How to Get Off Emergency Tax (Important)
In most cases, emergency tax is fixed automatically once HMRC:
- Receives your employment details
- Assigns the correct tax code
However, you can speed it up by:
- Completing a starter checklist
- Updating your details with HMRC
- Making sure your employer has your correct information
Once corrected, overpaid tax is refunded.
Will You Get the Money Back?
Yes.
If you overpay tax due to emergency tax:
- HMRC will refund it
- Either through your payslip
- Or as a direct payment
Emergency tax is temporary, not permanent.
How Long Does Emergency Tax Last?
It usually lasts:
- A few weeks
- Sometimes a couple of months
Once your tax code is updated, pay returns to normal.
Common Emergency Tax Myths
- ❌ “I’m being fined”
- ❌ “Foreigners pay more tax”
- ❌ “I’ll never get the money back”
- ❌ “I did something wrong”
None of these are true.
Final Honest Advice
If you’re a foreign worker and your pay looks wrong:
- Check your tax code first
- Don’t panic
- Emergency tax is common and fixable
Thousands of foreign workers go through this every year.
