Why monthly checking matters
Most payroll errors are silent until they compound. A USC band misapplied in March keeps repeating until someone notices. By the time you see a wrong number on the December payslip, you have lost ten months of earnings to fix retrospectively. Monthly monitoring catches drift in the period it occurs, when it is easiest to correct with HR or your payroll team.
How it works
- Upload or email: drag a payslip into the dashboard, or forward it to a unique secure email address tied to your account.
- Automatic compare: the engine matches each line against last month, last year, and the 2026 expected value.
- Alerts: any deviation greater than 1 euro or 1% (whichever is larger) triggers an alert via email and dashboard notification.
- Trend chart: 12 month rolling chart of gross, net, PAYE, USC, PRSI, and pension.
- Year end: a Statement of Liability prep pack is generated in January, ready to upload to Revenue myAccount.
What gets flagged
- Sudden change in tax credit applied (mid-year credit changes are normal but should be visible).
- Move from cumulative to Week 1/Month 1 basis (often a sign of a Revenue Payroll Notification refresh).
- Emergency tax episode after a job change.
- USC band applied incorrectly to a bonus.
- PRSI rate change application: should switch from 4.1% to 4.2% on the 1 October 2026 boundary.
- Pension contribution drift if your scheme percentage changes.
- Benefit-in-kind on a new company car or health insurance scheme.
Worked example
Eimear is a marketing manager in Cork on 55,000 euro a year. In April her bonus of 4,000 euro is paid. Monitor confirms:
- The bonus is taxed at 40% PAYE because it pushes her over the 44,000 SRCOP for the year.
- USC at 4% on the bonus portion.
- PRSI at 4.1% on the gross.
- Net effect: 4,000 euro gross becomes roughly 1,950 euro net.
If her employer instead taxed the bonus at the 20% rate (a common slip), Monitor would flag a roughly 800 euro under-deduction in real time, before the year-end balance shock.
Statement of Liability assistance
In January each year, Monitor produces a one-page summary that maps directly onto the fields Revenue asks for in the Statement of Liability flow. Specifically:
- Cumulative gross income for the year.
- Cumulative PAYE, USC, and PRSI deducted.
- Tax credits used.
- Reliefs you may have missed: medical expenses, work from home, flat rate expenses, Rent Tax Credit.
