Emergency Tax
in Ireland (2026)

Emergency tax is a temporary, higher rate of tax your employer must apply when Revenue has not yet linked your job to your tax record. With no instruction from Revenue about your tax credits and rate band, your employer taxes you cautiously, so you take home much less than you should. The good news: it is fully refundable, and easy to fix.

It is not a penalty and it is not extra tax you owe. It is a default your employer is legally required to fall back on the moment they run payroll with no valid Revenue Payroll Notification (RPN) for you: rather than guess your credits and cut-off point, the law makes them assume you have none. Every euro withheld on the emergency basis still belongs to you; it simply sits with Revenue instead of your bank account until the paperwork catches up, and once it does, the balance comes back through your payslip, not as a separate application you have to chase.

It almost always comes down to your new job not being set up with Revenue yet. The usual reasons:

• You started a first or new job and haven't given your employer your PPSN.
• You haven't registered the employment in Revenue's myAccount.
• As a result, your employer has no Revenue Payroll Notification (RPN): the message from Revenue that tells them your tax credits and cut-off point.
• You've taken on a second job without registering that employment separately: Revenue tracks each employer relationship on its own, so working for a new employer while still employed elsewhere needs its own registration too.
• You had a gap between jobs, for example a spell on a jobseeker's payment, and the new employment wasn't opened in myAccount before the first payday.

None of these need to be your fault. An employer can be slow to look up an RPN even after you've done everything right, or a payroll run can close before Revenue's response comes back. What determines whether you're taxed on the emergency basis is purely whether your employer has a valid RPN in hand on the day they run payroll, not whether you've ever worked or paid tax in Ireland before. Someone on their fifth job in ten years is exposed to it exactly as much as someone starting their first.

How you're taxed on the emergency basis depends on whether Revenue has your PPSN:

The key sting is that no tax credits are applied on the emergency basis, so even in the first four weeks you pay more than normal, and after four weeks everything is taxed at the top 40% rate plus 8% USC. That's why emergency-taxed payslips look so small.

Notice that the softer row is measured in weeks, not payslips, and that matters more than it looks. If you're paid weekly, "the first four weeks" means your first four payslips get the gentler 20%/40% split before you drop to flat 40%. If you're paid monthly, though, four weeks is essentially one payslip: your very first month's pay uses the softer rule, and your second month, still only your second payslip in the job, is already on the flat 40% rate with no credits at all. Two people who start on the same day, one paid weekly and one monthly, spend the same four calendar weeks unregistered but the monthly earner reaches the harsher rate three payslips sooner, purely because of how few payslips they get in that window. That's specific to the emergency basis; how pay frequency affects a normally-taxed payslip is a separate question, covered in our weekly vs monthly pay and tax guide.

Most people assume emergency tax is a first-job problem: something that happens to a graduate or a new arrival who hasn't dealt with Revenue before. In practice, it just as often catches someone who has been paying Irish tax correctly for years and has simply moved employer.

Revenue does not carry your credits and cut-off point from your old job across to your new one automatically. When you leave a job, your old employer's final payroll submission tells Revenue that employment has ended, which closes off that RPN. Your new employer, though, is a completely separate registration, and Revenue has no way of knowing you've started there until you tell it. If you start the new job and your first payday arrives before you've registered the new employment in myAccount, your new employer runs payroll with no RPN for you at all, exactly as if it were your first job ever, and applies the same emergency basis.

The trap is timing rather than ignorance: someone confident they "already sorted this with Revenue years ago" can genuinely believe there's nothing left to do. Register the new employment as soon as you have a start date, definitely before your first payday there. A short gap between jobs, including a period on a jobseeker's payment, doesn't change the mechanics: it's still the new employer's registration that has to exist before that employer's first payroll run.

Three steps. Do them as early as you can, ideally before your first payday:

1. Give your employer your PPSN (Personal Public Service number). If you don't have one yet, apply for it through MyWelfare / the Department of Social Protection.
2. Register the job in Revenue's myAccount: go to "Jobs and Pensions" and add your new employment (you'll need your employer's registration number, which is on your payslip).
3. Revenue then issues a Revenue Payroll Notification (RPN) to your employer with your correct tax credits and cut-off point.

Once your employer picks up the RPN, your next payslip is calculated on the normal cumulative basis, and the tax you overpaid is refunded through your pay automatically.

An RPN that lands after payroll has already run for that period does you no good until the following one, so even doing everything right and on time can still mean one emergency-taxed payslip if the registration and the payroll run land in the same pay period. That's a processing-order problem, not a mistake on your part, and it corrects itself on the very next payslip.

In most cases you don't have to do anything extra for the refund, and there is no separate payment to wait on: it comes back inside your ordinary payslip, not as a cheque, a bank transfer, or anything you claim yourself. Once your employer's payroll software picks up the corrected RPN, it recalculates your cumulative PAYE and USC due on your whole year-to-date pay using your real credits and cut-off, exactly as it should have been doing from day one. Because you were overcharged on every payslip up to that point, that recalculation comes out negative for the period it lands in: the software offsets that shortfall against the tax due for the current pay period, so your deduction for that one payslip is reduced, sometimes to zero, until the overpayment is used up.

If the amount owed back is larger than one period's normal tax bill, the offset simply carries into the following payslip too, rather than paying out in one lump sum. Either way, the giveback shows up as a smaller-than-usual PAYE line on a payslip you'd otherwise recognise, which is exactly why people sometimes miss that they've been refunded at all: nothing on the payslip is labelled "emergency tax refund".

If you've already left the job before it was fixed, or it's near year-end, there's no more payroll left to run the correction through, so you can claim the overpaid tax back directly from Revenue by reviewing your tax for the year in myAccount. See our guide to filing a tax return and claiming a refund.

Say you start a new job on a €40,000 salary, hand over your PPSN on day one, but your new employer's first payroll run happens before your registration reaches Revenue. Once it's sorted and your employer is applying your real credits and cut-off on the normal basis, a single person on €40,000 in 2026 keeps €2,798 a month: €333 in PAYE, €61 in USC and €141 in PRSI, an effective rate of 16.07%.

Your first payslip, before that registration lands, looks nothing like it. €40,000 a year sits entirely inside the 20% standard band, so on the normal basis none of it should ever be taxed at 40%. On the emergency basis, though, none of your personal or PAYE credits apply, so PAYE alone runs noticeably higher than the €333 shown above, even though every euro is still nominally in the 20%/40% split from the rates table. If that first registration still hasn't gone through by your second payday, the softer split disappears entirely and the whole month is taxed at a flat 40%, double the standard rate, with USC's flat 8% on top of that in either case. The gap between that payslip and the €2,798 you're entitled to isn't lost: it's exactly what comes back once the RPN arrives.

Assuming a wider band or extra credits carry over during the mild phase. The softer first four weeks (or first month) in the table above is calculated against the single person's standard cut-off, not whatever your real filing status entitles you to. A married applicant, someone with dependants, or anyone entitled to a wider band than a single person gets exactly the same narrower emergency cut-off as everyone else during that phase, because your employer has no RPN to tell them otherwise. The shortfall for someone actually entitled to more than the single band is bigger than the rates table alone suggests, and it corrects the same way as everyone else's: once the real RPN lands and your true credits and cut-off are applied.

Assuming USC gets worse after four weeks the way PAYE does. It doesn't. Look at the rates table again: USC sits at a flat 8% in every row, the mild phase and the harsh one alike. The step up from the softer 20%/40% split to a flat 40% after week four (or month one) is a PAYE-only change; USC is already charged at its worst rate from your very first payslip, whether you've been on emergency tax for a day or several months. Watching for USC to "step up" the way PAYE does is watching for something that was never going to happen.

The emergency basis rules and the RPN process: Revenue's own PAYE guidance on emergency tax and Revenue Payroll Notifications, and Citizens Information's plain-English summary of starting a new job, govern everything on this page other than the worked example.

The worked example: calculated by the IrishPAYE engine at 2026 PAYE, USC and PRSI rates for a single employee aged 30 on standard credits, the same engine behind every figure on this site. Married couples, other ages, a medical card or anyone with their own certificate of tax credits will differ, which is what the calculator is for.
