Starting a new job in Ireland should be an exciting time, but discovering that a significant chunk of your hard-earned wages has been deducted under emergency tax can quickly dampen your enthusiasm. If you've recently begun new employment and noticed your payslip is considerably lighter than expected, you're likely caught in Ireland's emergency tax system. The good news? You're almost certainly entitled to a refund, and understanding how to claim it back could put €500 to €1,500 back in your pocket.
What Is Emergency Tax and Why Are You Paying It?
Emergency tax is Revenue's default position when they don't have the correct information to tax you properly. This typically happens when you start a new job without providing either a P45 from your previous employer or completing a Job Registration Form (previously known as Form 12A) with Revenue beforehand.
When your new employer doesn't receive the necessary documentation, they have no choice but to place you on emergency tax. This isn't a penalty—it's simply a protective mechanism to ensure Revenue collects tax, albeit at rates that are usually far higher than what you actually owe.
How Emergency Tax Rates Work in Ireland
The emergency tax rate structure in Ireland operates on a tiered system:
- Week 1-4: 20% tax rate with no tax credits applied
- Week 5 onwards: 40% tax rate on all income with no tax credits
- USC: Applied at standard rates (0.5% to 8% depending on income)
- PRSI: 4% on all income over €352 per week
Real Examples: How Much Emergency Tax Costs You
Example 1: Retail Worker Starting New Job
Sarah earns €500 per week in her new retail position. She didn't have her P45 and worked for 8 weeks on emergency tax before getting her tax sorted.
Weeks 1-4 (Emergency Tax):
- Tax deducted: €400 (€500 × 20% × 4 weeks)
Weeks 5-8 (Higher Emergency Rate):
- Tax deducted: €800 (€500 × 40% × 4 weeks)
What she should have paid (with proper tax credits):
- Approximately €320 total over 8 weeks
Potential refund: €880
Example 2: Graduate Starting First Professional Role
James secured his first graduate position earning €700 per week. As a first-time employee, he had no P45 and wasn't aware he could register with Revenue beforehand. He remained on emergency tax for 12 weeks.
Emergency tax paid over 12 weeks:
- Weeks 1-4: €560 (€700 × 20% × 4)
- Weeks 5-12: €2,240 (€700 × 40% × 8)
- Total emergency tax: €2,800
Correct tax with credits applied:
- Approximately €1,440 over 12 weeks
Potential refund: €1,360
Example 3: Healthcare Worker Switching Employers
Maria changed hospitals mid-year, earning €1,000 per week. Her previous employer delayed issuing her P45, leaving her on emergency tax for 6 weeks when starting her new job.
Emergency tax deductions:
- Weeks 1-4: €800 (€1,000 × 20% × 4)
- Weeks 5-6: €800 (€1,000 × 40% × 2)
- Total emergency tax: €1,600
Correct tax liability:
- Approximately €540 over 6 weeks
Potential refund: €1,060
How to Claim Your Emergency Tax Refund
While Revenue will eventually process refunds through your ongoing payroll once your tax credits are properly allocated, this process can take months. Many workers unknowingly leave money on the table because they assume Revenue will automatically sort everything out.
The reality is that navigating the refund process requires understanding which forms to submit, ensuring all previous employments are properly declared, and verifying that your tax credits and rate bands have been correctly applied. This is where professional assistance becomes invaluable. Tax professionals can identify overpayments you might not notice and ensure you receive every euro you're entitled to, often expediting the process significantly.
Understanding how long your emergency tax refund takes depends on several factors, but professional help typically accelerates the timeline from months to weeks.

Frequently Asked Questions
How do I know if I've been placed on emergency tax?
Check your payslip for the tax basis indicator. "Week 1" or "Week 1/Month 1" indicates emergency tax. You'll also notice significantly higher tax deductions than expected, with little or no tax credits showing. Your take-home pay will be substantially less than you calculated based on your gross salary.
Can I claim back emergency tax from previous years?
Yes, you can claim a tax refund for up to four years back. If you were on emergency tax in 2021, 2022, 2023, or 2024 and never claimed your refund, you're still entitled to it. Many workers are surprised to discover they have unclaimed refunds sitting with Revenue from jobs they've long forgotten about.
Will my employer automatically sort out my emergency tax?
Your employer will move you to the correct tax once they receive your P45 or Revenue allocates proper tax credits. However, this doesn't automatically trigger a refund of the emergency tax already paid. You need to actively claim this overpayment, and many people wait unnecessarily long or miss out entirely by assuming it happens automatically.
How much emergency tax refund should I expect?
Typical refunds range from €500 to €1,500, depending on your salary and how long you remained on emergency tax. Higher earners who stayed on the 40% emergency rate for several weeks often see refunds exceeding €1,000. The exact amount depends on your income level, how long you were on emergency tax, and what tax credits you're entitled to.
What happens if I have multiple jobs in one year?
Having multiple employments in a single tax year complicates matters significantly. Your tax credits and rate band can only be fully applied to one job at a time. If you switched employers, especially without providing a P45, you've almost certainly overpaid tax. Professional review of multi-employer situations often uncovers substantial refunds that wouldn't be obvious from a single payslip.
