How is commission taxed in Ireland?
In many payroll setups, commission is treated as taxable pay. It can be subject to PAYE, USC and PRSI, depending on your circumstances and payroll settings.
Why does my commission month look more heavily taxed?
Commission often arrives as a one-off uplift in a month. That additional income can sit in higher PAYE and USC bands for the period, and PRSI may also apply.
How can I estimate my commission take-home pay?
Model a base scenario and a scenario with higher annual income. Compare the change in net pay and total deductions. Treat results as scenario estimates rather than payslip reconciliation.
