Why does PRSI look different across 2026?
PRSI can change due to rate updates during the year. Your payroll timing and how the change is applied can affect what you see on a payslip in a given month.
Does this page reconcile my payslip?
No. This is scenario guidance for planning. Payslip reconciliation depends on your PRSI class and your employer’s payroll settings.
How should I use the PRSI timing toggle on the calculator?
Use it to compare scenarios for budgeting: “Jan–Sep” versus “Post-Oct”. Treat the difference as an estimate rather than a guarantee of payroll treatment.
