Starting a new job in Ireland is an exciting milestone, but it can quickly become stressful when you notice a significantly smaller paycheck than expected. If you've found yourself in this situation, you're likely on emergency tax—a common issue affecting thousands of Irish workers every year. The good news? Once resolved, most people receive refunds between €500 and €1,500, making it well worth addressing immediately.
Emergency tax occurs when your new employer doesn't have the proper documentation to tax you correctly from your first day. Understanding why this happens, how much it could cost you, and most importantly, how to claim back what's rightfully yours, is crucial for anyone starting a new job in Ireland.
Why Am I on Emergency Tax in My New Job?
When you start a new job in Ireland, your employer needs specific documentation to tax you correctly. Without either a P45 from your previous employer or a completed Revenue Job Registration Form, they're legally required to place you on emergency tax. This isn't a mistake or oversight—it's a protective measure built into the Irish tax system.
The most common reasons for being placed on emergency tax include:
- Starting your first job in Ireland and having no previous P45
- Losing or not receiving your P45 from a former employer
- Moving from self-employment to PAYE employment
- Returning to the workforce after an extended break
- Starting employment as a recent graduate
- Administrative delays between you, your employer, and Revenue
How Emergency Tax Rates Work in Ireland (2025)
Understanding the emergency tax rate in Ireland is essential for calculating how much you might be owed. The system operates on a week-by-week basis with escalating rates:
Weeks 1-4: You're taxed at 20% on all your income, but you receive no tax credits. For 2025, standard employees should receive a €1,775 annual tax credit (€34.13 per week), but emergency tax gives you nothing.
Week 5 onwards: The rate jumps to 40% on your entire income—not just on amounts over a threshold. This is where emergency tax becomes particularly expensive.
USC (Universal Social Charge) and PRSI are deducted normally, but the absence of tax credits and the blanket 40% rate from week five onward means you're substantially overpaying.
Real Examples: How Much Emergency Tax Could Cost You
Example 1: Junior Professional (€35,000 Annual Salary)
Sarah starts a new marketing role on January 15th, 2025, earning €35,000 annually (€673 weekly). She doesn't have her P45, and it takes 8 weeks to resolve.
Emergency tax paid:
- Weeks 1-4: €673 × 20% × 4 weeks = €538.40
- Weeks 5-8: €673 × 40% × 4 weeks = €1,076.80
- Total emergency tax: €1,615.20
Correct tax (with credits): Approximately €485.60 for 8 weeks
Potential refund: €1,129.60
Example 2: Mid-Career Professional (€55,000 Annual Salary)
Michael starts a new software development position earning €55,000 annually (€1,058 weekly). He waits 6 weeks before seeking help with his emergency tax situation.
Emergency tax paid:
- Weeks 1-4: €1,058 × 20% × 4 weeks = €846.40
- Weeks 5-6: €1,058 × 40% × 2 weeks = €846.40
- Total emergency tax: €1,692.80
Correct tax (with credits): Approximately €967.20 for 6 weeks
Potential refund: €725.60
Example 3: Recent Graduate (€30,000 Annual Salary)
Emma secures her first graduate position at €30,000 annually (€577 weekly). As a first-time employee, she has no P45 and remains on emergency tax for 10 weeks before addressing it.
Emergency tax paid:
- Weeks 1-4: €577 × 20% × 4 weeks = €461.60
- Weeks 5-10: €577 × 40% × 6 weeks = €1,384.80
- Total emergency tax: €1,846.40
Correct tax (with credits): Approximately €385.00 for 10 weeks
Potential refund: €1,461.40
How Long Does an Emergency Tax Refund Take?
The timeline for receiving your emergency tax refund in Ireland depends on how quickly you act and which method you choose. Once you submit the necessary documentation to Revenue, the typical processing time is between 2-4 weeks, though this can extend during busy periods.
However, many people delay addressing emergency tax because they assume it will resolve automatically. While your tax situation may eventually correct itself when Revenue processes your information, you could wait months—and during that time, you're losing 40% of every paycheck from week five onwards. The financial impact of waiting can easily reach €2,000 or more for higher earners.
Professional tax rebate services expedite this process by ensuring all documentation is complete and correctly submitted the first time, avoiding the back-and-forth that extends timelines. To understand more about how long emergency tax refunds take, the key is acting quickly and getting expert assistance.
Steps to Resolve Emergency Tax When Starting a New Job
Taking immediate action is crucial to minimizing how much you overpay. Here's what needs to happen:
- Obtain your P45: If you left a previous job, contact that employer immediately to request your P45 if you haven't received it.
- Complete a Form 12A: If you don't have a P45 (first job, returning after a break, etc.), you'll need to register with Revenue as a new employee.
- Verify your tax credits: Ensure Revenue has allocated your correct tax credits and rate bands to your new employer.
- Claim your refund: Once your tax situation is corrected, you need to file for a refund of overpaid tax—this doesn't happen automatically for past weeks.
- Get professional help: Tax professionals understand the intricacies of emergency tax claims and can maximize your refund while handling all documentation and follow-up.
⚠️ Important: Even after your current tax situation is corrected with your employer, you still need to claim back the emergency tax you've already paid. This requires filing a separate claim with Revenue, which many workers overlook.
Why Professional Help Maximizes Your Emergency Tax Refund
While it's technically possible to handle emergency tax claims yourself, the complexity of Irish tax law means many people either miss additional refunds they're entitled to or make errors that delay the process significantly. Professional tax rebate specialists offer several advantages:
- Complete review: Professionals examine your entire tax situation, often identifying additional refunds beyond just emergency tax
- Accurate calculations: Complex interactions between tax credits, rate bands, USC, and PRSI require expertise to calculate correctly
- Faster processing: Correctly completed claims with all necessary documentation move through Revenue much faster
- Maximum refund: Experts ensure you claim every euro you're entitled to, including refunds many people don't know exist
- No upfront costs: Reputable services only charge a percentage of successful claims, meaning no risk to you
Frequently Asked Questions About Emergency Tax on New Jobs
Will my emergency tax refund happen automatically?
No, this is a common misconception. While your employer will correct your tax rate going forward once they receive the proper documentation, you must file a separate claim with Revenue to recover emergency tax you've already paid in previous weeks. Without filing this claim, you won't receive your refund.
How much can I expect to get back from emergency tax?
Most people receive between €500 and €1,500 when their emergency tax situation is resolved, though the exact amount depends on your salary, how long you were on emergency tax, and your correct tax credits. Higher earners who remain on emergency tax for several months can receive €2,000 or more.
What if I don't have my P45 from my previous employer?
If you cannot obtain your P45, you'll need to register as a new employee with Revenue using Form 12A or through Revenue's online system. This informs Revenue about your new employment and allows them to issue your tax credits to your new employer. A tax professional can handle this registration efficiently and ensure it's processed quickly.
Can I claim emergency tax back from previous years?
Yes, you can claim emergency tax refunds for up to four previous tax years. Many people don't realize they were entitled to refunds from past jobs, and these unclaimed amounts can add up significantly. A comprehensive review of your tax history can uncover refunds from multiple years.
What's the difference between emergency tax and the higher tax rate?
Ireland's standard higher tax rate of 40% applies only to income above €42,000 (for 2025), and you still receive your tax credits. Emergency tax after week four charges 40% on ALL your income with NO tax credits, meaning you pay far more than the standard system. Even someone earning €30,000 would pay 40% under emergency tax from week five onwards—something that would never happen under normal taxation.
