Being Emergency Taxed? Act Quickly

Emergency tax can result in significant overpayment, especially for NHS staff with multiple employers or complex pay arrangements. The sooner you act, the faster you'll get your money back.

Understanding Emergency Tax Codes

Emergency tax codes are applied when HMRC doesn't have enough information about your circumstances. For NHS staff, this commonly happens with bank work, locums, or job changes.

Tax CodeWhat It MeansTax RateWhen Applied
1257L W1Basic emergency code (weekly)20%/40%/45% on cumulative basisNew job, no P45
1257L M1Basic emergency code (monthly)20%/40%/45% on cumulative basisMonthly paid staff
BRBasic Rate - all income taxed20% on all earningsSecond job/pension
D0Higher Rate - all income taxed40% on all earningsHigh earner, second job
D1Additional Rate - all income taxed45% on all earningsVery high earner
0TNo personal allowanceTax from £1Complex circumstances

NHS-Specific Emergency Tax Scenarios

Bank/Agency Work: Often gets BR code (20% on everything) instead of cumulative calculation
Locum Sessions: Treated as second employment, typically BR or higher rate codes
Job Changes: New trust without P45 triggers emergency code
Return from Leave: Maternity/career break returns sometimes trigger emergency codes

Multiple Employer Tax Code Issues

NHS staff frequently work for multiple employers (main job + bank work + private practice). This creates complex tax situations that often result in emergency codes.

How It Should Work

  • • Main job gets your full tax code (e.g., 1257L)
  • • Secondary jobs get BR code (20%)
  • • HMRC balances annually via self-assessment
  • • Real-time information (RTI) tracks all earnings

Common Problems

  • • All jobs get emergency codes
  • • Higher rate codes applied incorrectly
  • • Personal allowance split between employers
  • • RTI system confusion with similar names/NINo

Real Example: Consultant with Multiple Roles

What Should Happen:

  • • Main NHS job: 1257L (£12,570 allowance)
  • • Private practice: BR (20% all earnings)
  • • Locum work: BR (20% all earnings)

Emergency Tax Reality:

  • • Main NHS job: 1257L W1 (weekly emergency)
  • • Private practice: D0 (40% all earnings)
  • • Locum work: D1 (45% all earnings)
Result: Overpaying thousands in tax monthly, requiring refund claims.

Bank and Agency Work Tax Problems

Common Issue: Treated as Primary Employment

NHS bank work is often incorrectly processed as your primary employment, giving it your main tax code instead of BR.

Correct:

Bank work: BR code (20% flat rate)

Main job: 1257L (full allowances)

Wrong:

Bank work: 1257L (gets all allowances)

Main job: BR (20% on everything)

Agency Work Complications

Working through agencies adds complexity as they may not have your correct tax information.

  • • Each agency may apply different emergency codes
  • • Off-payroll working (IR35) rules may apply
  • • Multiple P60s at year-end create confusion
  • • Some agencies poor at processing P45s

P45/P60 Missing Documents

P45 Issues

When You Need It:

  • • Starting new NHS job
  • • Moving between trusts
  • • Returning from unpaid leave

If Missing:

  • • Emergency tax code applied
  • • Complete starter checklist

P60 Problems

What P60 Shows:

  • • Total pay for tax year
