Why does my second job feel taxed at a higher rate?
A common reason is that most credits and rate bands are applied to your main job. The second job can have less credit coverage, so more of its pay can be charged at higher marginal rates.
Is there a special “second job tax” in Ireland?
Not usually. The effect is typically credit and band allocation plus marginal deductions (PAYE, USC and PRSI) stacking on additional income.
How can I estimate take-home pay from a second job?
Model total annual income and compare scenarios. Use sensitivity by adjusting credits assumptions, and treat results as planning estimates rather than payslip reconciliation.
