Emergency Tax Rates Ireland: 40% and 8% USC Explained 2025
Detailed breakdown of Irish emergency tax rates: why 40% income tax and 8% USC are applied, how they compare to normal rates, and the financial impact on your paycheck.
Emergency Tax Rate Breakdown
Emergency tax applies flat rates: 40% income tax + 8% USC + 4% PRSI = 52% total on ALL income. Normal rates for €40,000 earner: effective 20% income tax + ~2% USC + 4% PRSI = ~26% total. Emergency tax doubles your deductions.
The 40% Emergency Income Tax Rate
Emergency tax applies Ireland's higher income tax rate (40%) to ALL income, regardless of amount. This is fundamentally different from normal tax system:
Normal Income Tax
- ✓ 20% on first €44,000 (single person)
- ✓ 40% only on income above €44,000
- ✓ Tax credits reduce liability (€3,550 annually for single PAYE worker)
- ✓ Cumulative calculation across year
Result: Most workers pay effective 10-15% income tax
Emergency Income Tax
- ✗ 40% on ALL income from €1
- ✗ No distinction between lower/higher rate bands
- ✗ ZERO tax credits applied
- ✗ Week 1 basis (no cumulative benefit)
Result: Workers pay effective 40% income tax
The 8% Emergency USC Rate
Universal Social Charge (USC) normally uses tiered rates from 0.5% to 8% depending on income level. Emergency tax applies the highest USC rate (8%) to all income:
Normal USC vs Emergency USC
| Income Band | Normal USC Rate | Emergency USC Rate |
|---|---|---|
| First €12,012 | 0.5% | 8% |
| €12,013 - €25,760 | 2% | 8% |
| €25,761 - €70,044 | 4% | 8% |
| Above €70,044 | 8% | 8% |
For €40,000 salary: Normal USC = ~€800. Emergency USC = €3,200. Extra €2,400 deducted annually.
Total Emergency Tax Deductions
Emergency tax combines three components:
- Income Tax: 40% flat rate on all income
- USC: 8% flat rate on all income
- PRSI: 4% (same rate as normal employment)
Total Emergency Deduction: 52% of gross pay

Why These Specific Rates?
Emergency tax rates are deliberately set at maximum levels for several reasons:
- Revenue Protection: High rates ensure Revenue collects sufficient tax upfront rather than risking underpayment
- Compliance Incentive: Painful rates motivate employees to provide correct documentation quickly
- Simplification: Flat rates are administratively simple for employers to apply without detailed taxpayer information
- Refund Guarantee: Setting rates high means emergency tax always results in overpayment, creating automatic refund entitlement rather than underpayment risk
How Long You Pay These Rates
Emergency rates apply only temporarily:
- Typical duration: 2-6 weeks until Revenue issues correct tax certificate
- With P45 provided: Usually 2-3 weeks
- Without P45: 4-6 weeks
- PPS issues: 6-12 weeks if PPS registration delayed
Automatic Refund
Once correct tax code applied, your employer automatically recalculates year-to-date tax, identifies overpayment from emergency tax period, and refunds excess through your next wage payment. All overpaid emergency tax is recovered.
Annual Impact If Not Corrected
If emergency tax remained uncorrected for full year (rare but possible with PPS/immigration issues):
Full Year Emergency Tax Impact
€30,000 salary: Pay €15,600 tax vs. €2,050 normal = €13,550 overpayment
€40,000 salary: Pay €20,800 tax vs. €4,650 normal = €16,150 overpayment
€50,000 salary: Pay €26,000 tax vs. €8,650 normal = €17,350 overpayment
All overpayments refundable at year-end or when corrected
