Emergency tax in Ireland: why it happens and the fast fix

New job, first payslip, and nearly half your pay is gone: that is emergency tax. It can hit anyone who starts a job in Ireland before the paperwork chain is complete, and the overpaid tax is normally refunded once your record is fixed.

Why it happens

Irish payroll runs on the RPN (Revenue Payroll Notification): Revenue tells your employer your rate band and tax credits. No RPN (because you have no PPSN yet, or you didn't register the job in myAccount) means the employer must apply emergency rules: with a PPSN, four weeks of single-person band with zero credits sliding to 40% on everything; without a PPSN, 40% from the first euro. Emergency USC adds 8%.

The two-step fix

  • Get a PPSN (if you don't have one) via MyWelfare, often the bottleneck for new arrivals.
  • Register the job in Revenue myAccount ("Add job or pension") with your employer's registration number. Revenue then issues an updated RPN to your employer, and the next payroll run applies the normal credits and bands.

Getting the money back

Because Irish PAYE is cumulative, the refund usually arrives automatically in the next payslips after the RPN lands: payroll recalculates the year to date and returns the excess. If the year ends first, request a Statement of Liability in myAccount in January and the refund is paid directly. Overpaid tax is normally refunded this way, just later.

What normal looks like

Once your credits apply, a €40,000 single earner takes home about €2,798 a month. If your post-fix payslip still looks wrong, compare it against the salary calculator and check whether your credits are split across an old job.

Avoiding it entirely

Register the new job in myAccount as soon as you accept the offer. You need the employer number from HR, and it takes five minutes. Moving jobs? Your old employment's cessation goes to Revenue electronically; registering the new one early keeps the chain unbroken.

Frequently asked questions

How do I get off emergency tax in Ireland?

Register the new job in Revenue myAccount using the employer registration number from HR. Revenue will issue an updated Revenue Payroll Notification to your employer, and the next payroll run will apply your normal credits and rate band.

Will I get a refund of emergency tax that was overpaid?

Yes. Irish PAYE is cumulative, so overpaid tax is usually refunded automatically in the next payslips once the Revenue Payroll Notification is updated. If the tax year ends first, request a Statement of Liability in myAccount in January.

What tax rate applies if I have no PPSN when starting a new job?

Without a PPSN your employer must deduct 40% from the first euro of pay with no tax credits applied. Once you obtain a PPSN and register the job in myAccount, normal rates and credits apply from the next payroll run.
