Why does overtime feel taxed so heavily?
Overtime is usually taxed like salary, but the extra income often sits in higher PAYE and USC bands. When PAYE, USC and PRSI apply on the same extra euro, the combined marginal deduction can look high.
Is overtime taxed differently from normal salary?
In many payroll setups, overtime is normal taxable pay. The difference is typically the marginal position of that pay rather than a separate “overtime tax”.
How can I estimate take-home pay from overtime?
Model a base salary scenario and an “extra income” scenario, then compare the change in net pay and the change in total deductions. Treat the result as scenario-based.
