Why your first payslip looks brutal

Emergency tax is what happens when your new employer runs payroll without a Revenue Payroll Notification, the RPN, for you. The RPN is the electronic instruction that tells the employer your tax credits and your standard rate cut-off point. Until it arrives, payroll has to assume the worst and tax you on the emergency basis. The good news is that none of this is lost. Every euro over-deducted comes back to you, either automatically through payroll once the RPN loads or through Revenue at year end. The bad news is that the first one or two payslips can be painful, and the size of the hit depends entirely on whether your employer has your PPSN.

PPSN or no PPSN: two very different outcomes

With a PPSN on file, the emergency basis is relatively gentle at the start. You get a temporary standard rate cut-off point and a temporary tax credit for the first weeks, so a normal salary is barely touched beyond what you would pay anyway. The cut-off then tapers and, after about four weeks, everything is taxed at the 40% higher rate until the RPN sorts it out. Without a PPSN it is far harsher from day one: all of your pay is taxed at 40% with no credits and no cut-off at all. That single missing number is the difference between a minor delay and losing close to half a payslip, which is why handing your PPSN to the employer before your first payday is the most useful thing you can do.

A €3,000 month with no PPSN, line by line

Take a monthly salary of €3,000 where the employer does not yet have your PPSN. On the emergency basis, the full €3,000 is taxed at the 40% higher rate, which is €1,200 of income tax, with no credits applied. USC still runs on top in the normal way, adding about €52 for the period. So the emergency deduction is roughly €1,252. Your normal tax for that month, with your credits and the standard cut-off in place, would be only about €319. The gap of €933 is the overpayment you will reclaim.

The chart puts the emergency deduction next to the tax you should have paid. The dark slice on the left is the €933 you get back.

How to switch it off and get the money back

The fix is almost always simple: register the new job in Revenue myAccount under Jobs and Pensions, giving your new employer’s registration number. That prompts Revenue to issue the RPN to your employer, and once payroll picks it up your credits and cut-off are restored. If the over-deduction happened earlier in the same employment, the refund usually flows back through your next payslip on a cumulative basis. If the job has ended or year end has passed, you claim it back through your Revenue Statement of Liability. A practical tip for anyone starting a job in a new tax year: log into myAccount and add the employment yourself on day one rather than assuming HR will trigger it, because the RPN often will not generate until Revenue knows the job exists. This tool is for the new starter, the returning emigrant, or the worker juggling a second job, anyone who wants to know in advance how much of the first payslip is a temporary loan to Revenue rather than real tax.

Common questions

How long does emergency tax last in Ireland?

It lasts only until Revenue issues an RPN to your employer, which is usually a matter of days once you register the job in myAccount and your PPSN is on file. In practice many people are caught on the emergency basis for one or two pay periods at the start of a job. The longer it drags on, the more likely it is that the job was never registered with Revenue, so check myAccount if a third payslip still looks heavily taxed.

Do I still pay USC and PRSI while on emergency tax?

USC is deducted on the emergency basis just as it is normally, so it shows up in the figures above. PRSI is a separate charge at a flat percentage and is generally not refunded as part of an emergency tax correction, because it is not based on credits or a cut-off point. The overpayment you reclaim is essentially the excess income tax, not your PRSI.

Frequently asked questions

How does emergency tax work in Ireland?
If your employer has no Revenue Payroll Notification for you, you go on the emergency basis. With a PPSN you get a temporary standard rate cut-off for about four weeks, then it reduces and everything is taxed at 40%. Without a PPSN, all pay is taxed at the higher rate from the start. You reclaim any overpayment once Revenue issues your credits.
How long does it take for Revenue to issue an RPN after I register my new job?
Revenue typically issues an RPN to your employer within one to two working days of you registering the new employment in myAccount under Jobs and Pensions. The RPN is transmitted electronically to your employer payroll system. If payroll runs before the RPN arrives, that pay period will still use the emergency basis. Once the RPN loads, future pay periods are corrected and any earlier overpayment is usually refunded through the next payslip on a cumulative basis.
Does PRSI get refunded when I was on emergency tax?
No. PRSI is charged at a flat rate on gross pay and is not based on tax credits or a standard rate cut-off. Emergency tax corrections made by Revenue cover excess income tax only. If you believe a PRSI error occurred, such as the wrong PRSI class being applied, you need to contact Revenue separately. USC, by contrast, is included in the overall PAYE reconciliation and any USC overpayment is refunded along with the income tax overpayment.
Can emergency tax apply to a second job in Ireland?
Yes. If you start a second job and do not register it with Revenue, or your employer does not yet have an RPN for you, the emergency basis applies in the same way. A second job often has no tax credits allocated to it by default because your credits and standard rate cut-off are typically already used against your first job. Revenue can split credits across multiple employments on request via myAccount, but without an RPN in place the second employer must deduct on the emergency basis regardless.
