Ireland does not use tax codes — it uses RPNs

If you have worked in the UK you will be used to a tax code like 1257L printed on every payslip. Ireland works differently. Instead of a code, Revenue sends your employer an electronic instruction called a Revenue Payroll Notification (RPN) before each pay run. The RPN carries four things that decide your net pay: your annual tax credits, your Standard Rate Cut-Off Point (SRCOP), your USC rate band, and whether tax should be calculated on the cumulative, Week 1/Month 1 or emergency basis. If any of those four values is wrong, every payslip after it is wrong too — and payroll will keep applying the bad instruction until Revenue issues a new one.

The numbers a single PAYE worker should expect in 2026

For a single person with one employment, the standard 2026 position is €4,000 in annual tax credits (€2,000 Personal credit plus €2,000 Employee PAYE credit) and an SRCOP of €44,000, meaning income up to €44,000 is taxed at 20% and the balance at 40%. Married couples and civil partners assessed jointly can have up to €53,000 at the standard rate where one spouse earns, or €88,000 between them where both earn. If the credits on your RPN are well below €4,000 and you have only one job, something needs explaining — commonly a clawback for underpaid tax in an earlier year, a benefit-in-kind adjustment, or credits still allocated to an employment you left.

The five most common RPN problems

  • Emergency basis. Revenue has no RPN for the employment, so payroll must apply emergency rules: a single week or month of standard-rate band and, after four weeks without a PPSN match, 40% tax on everything. Fix it by registering the job in myAccount. Our emergency tax guide walks through the steps.
  • Week 1/Month 1 basis. Each pay period is taxed in isolation with no carry-forward, so overpaid tax from earlier in the year is not refunded through payroll. Legitimate after a career break or unclear prior-year figures, but if it persists for months, ask Revenue to restore the cumulative basis.
  • Credits stuck with an old employer. After a job change, credits and SRCOP sometimes remain allocated to the previous employment, leaving the new one taxed with little or no credit. Reallocate them in myAccount under Manage Your Tax.
  • Split credits across two jobs. Splitting is correct if both jobs pay enough to use their share — but a poor split wastes credits or under-taxes you, creating a year-end bill. See our guide to allocating credits with a second job.
  • Missing credits you are entitled to. The Rent Tax Credit, Home Carer credit, flat-rate expenses for your occupation and remote-working relief all have to be claimed — Revenue does not add them automatically. The tax credits guide lists what is available.

How to check and fix your RPN

Log in to Revenue myAccount, open PAYE Services → Manage Your Tax 2026, and you will see the credits and rate band Revenue currently holds for each employment. Compare those against what the decoder above says you should expect. Changes you make — claiming a credit, reallocating the band, closing an old employment — generate a new RPN that your employer picks up at the next pay run, and on the cumulative basis any overpaid tax comes back automatically in that payslip. If you would rather start from the payslip itself, the free payslip checker reads your deductions and flags anything inconsistent with the 2026 rules, and the SRCOP guide explains how the rate band works in detail.
