You’ve just started a new job, opened your payslip, and noticed a massive chunk gone from your wages. It doesn’t add up. You were expecting a certain take-home amount, but instead you’ve been hit with a much smaller number. That’s often the moment people realise they’ve been put on emergency tax.
If this happens to you, don’t worry, you’re not the only one. Emergency tax is a common issue in Ireland, and it’s usually easy to fix once you know what’s going on.
This blog explains what emergency tax is, why it happens, how to fix it quickly, and how to make sure it doesn’t happen again.
Emergency tax is a temporary higher rate of income tax that’s applied when your employer doesn’t have the correct tax details for you. Instead of applying your personal tax credits and standard tax bands, they deduct a flat rate to be safe until Revenue confirms your information.
This system exists to make sure the government still collects tax, even when something’s missing or incorrect. But for workers, it usually means overpaying tax until it’s sorted.
There are a few common reasons people in Ireland end up on emergency tax:
Sometimes the issue is small, like a missed step in the Revenue system. Other times, it’s just a delay in paperwork or registering a new job. Either way, Revenue won’t issue your proper tax details to your employer until everything lines up.
When emergency tax kicks in, your full income is taxed at the higher rate once you pass a short exemption threshold. Here’s how it works:
For someone earning a normal salary, this means your take-home pay can drop by hundreds of euros each week until the emergency tax is removed.
There are a few clear signs:
The best way to confirm it is by logging into your myAccount on the Revenue website. You’ll be able to see what tax details have been sent to your employer and if an RPN has been issued.
The good news is that emergency tax is not permanent. It’s just a placeholder until Revenue gets the right info. Here’s how to sort it:
1. Register Your Job with Revenue
The fastest way to fix emergency tax is to let Revenue know where you're working. You can do this through your myAccount
This tells Revenue that you’ve started a new job, and they’ll issue an RPN to your employer with your correct tax bands and credits.
2. Give Your PPS Number to Your Employer
Make sure your employer has your correct PPS number. If they don’t, they won’t be able to link your tax info to Revenue. Even a small mistake in the number can block the whole process.
3. Check That You’re Only Using Credits in One Job
If you have two jobs, your tax credits may only be applied to one. You can log in to your myAccount and split your credits between employers as needed. If you don’t do this, the second job will often get taxed at the higher rate.
4. Wait for the Next Payroll
Once Revenue sends your updated tax info to your employer, the emergency tax will stop on your next payslip. You don’t have to wait months, it usually kicks in within the next pay cycle.
Yes. If you were taxed under emergency rules for a few weeks before it was fixed, the overpaid tax is refunded automatically through payroll.
Here’s how it works:
There’s no need to manually request the refund unless you leave the job before it gets sorted. In that case, you can request a refund directly from Revenue at the end of the tax year or through a tax agent.
Emergency tax is frustrating, but it’s also preventable. Here are a few things you can do to avoid it happening again:
Before you begin any new job, log in to your Revenue myAccount and register the job using the “Jobs and Pensions” service. This lets Revenue know who you’re working for and when you started. If you do this even a few days before your first payday, you’re much less likely to be taxed incorrectly.
Your employer needs your full name, PPS number, and start date to register you properly for payroll. If even one of these is missing or incorrect, Revenue can’t send your tax details. Always double-check your details on your first day.
If you had a job earlier in the year, Revenue might assume you’re still in it. This can cause issues if they think you’ve got two jobs when you only have one. Always let Revenue know when a job ends. You can do this from your myAccount as well.
If you’re working two jobs, your full tax credits will go to one by default. The second job will usually be taxed at the higher rate. To fix this, go to your myAccount and choose how you want to divide your tax credits between the two employers.
People returning to Ireland from working overseas often face emergency tax on their first payslip back. Before starting your new role, contact Revenue to update your address, employment status, and tax details. This can help you avoid emergency deductions when you re-enter the system.
Students getting their first job in Ireland are often emergency taxed because their details aren’t registered properly. Even if you’ve never worked before, you still need to log into myAccount, set up your record, and register for the job. It’s quick and can save you from losing out on your first pay.
Let’s say Sarah gets a new job in Dublin with a salary of €32,000 per year. She forgets to register the job with Revenue. Her first payslip shows a high deduction, over €400 more than she expected.
She checks her payslip and sees that no tax credits were applied, and all her income was taxed at 40 percent. That’s emergency tax.
Sarah logs into her myAccount, registers the job, and confirms her PPS number is correct with her employer. A few days later, Revenue issues a Revenue Payroll Notification (RPN) to her employer. On her next payslip, Sarah gets her full tax credits and a refund of the emergency tax she paid in her first week.
Problem solved, and she didn’t need to contact anyone directly or file any forms.
Yes. If you’re unsure why you were taxed so heavily, speak to your employer’s payroll team or accounts department. They can check whether they received your RPN or if they had to apply emergency tax because of missing details.
Employers are responsible for applying the correct rates, but they can only do that once Revenue sends them the right data. That’s why it’s so important to register your job as soon as you start.
If you only work a short-term job and leave before your tax issue is corrected, you might miss out on an automatic refund. But you can still claim it back.
Log into myAccount, review your Employment Detail Summary at the end of the tax year, and submit a request for a refund. Revenue will calculate what you overpaid and send the refund straight to your bank account.
You can also use an accountant or tax refund service if you want someone else to handle the paperwork, although many people can do it themselves without too much hassle.
Emergency tax is annoying, but it’s not the end of the world. It’s a short-term issue that can usually be fixed in a few clicks. The most common reason people end up on emergency tax is simply forgetting to register a new job or assuming their employer has sorted everything.
By using Revenue’s online system, keeping your details up to date, and taking a few minutes to check your payslip, you can avoid paying too much tax and make sure every cent of your wages ends up where it should, in your pocket.
Emergency tax is a temporary higher rate of tax applied when Revenue doesn’t have your correct job or income details. It’s used until your employer receives the proper tax information from Revenue.
This usually happens when you start a new job and haven’t registered it with Revenue, or your employer hasn’t received your Revenue Payroll Notification (RPN). It can also happen if your PPS number is incorrect or you’ve returned to work after a long break.
Emergency tax is charged at 40% on your income after a short initial exemption. You also won’t get your personal or PAYE tax credits, so your take-home pay is much lower than normal.
Check your payslip. If no tax credits are showing and you're being taxed at 40% from the start, you're probably on emergency tax. You can also check your Revenue myAccount to see if an RPN has been issued.
Log into Revenue myAccount and register your new job under the “Jobs and Pensions” section. Make sure your employer has your correct PPS number. Revenue will then send the correct tax details to your employer.
Once your job is registered and your details are updated, emergency tax usually stops on your next payslip. Your employer will apply the updated rates automatically once they receive the RPN from Revenue.
Yes. Once the issue is fixed, your employer will refund the overpaid tax through payroll. If you leave the job before it’s sorted, you can claim a refund from Revenue at the end of the tax year.
Not always. If you register your job through myAccount, Revenue will issue the correct tax details. But if something is still off, you can contact them by phone or use their online chat.
If you have more than one job, your tax credits may only be applied to one. The second job may be taxed at the higher rate. You can log in to myAccount and split your credits between employers.
Yes. Even if you’re on emergency tax, PRSI and USC will still be deducted from your gross pay as normal.
