How is a sign-on bonus taxed in Ireland?
A sign-on bonus is typically treated as taxable pay and can be charged PAYE, USC and PRSI. The exact outcome depends on payroll timing and your circumstances.
Why does the payslip deduction look so high on a sign-on bonus?
A large one-off payment can push you into higher marginal bands for that payslip. When multiple deductions apply together, the combined marginal deduction can look high.
How can I estimate the take-home value of a sign-on bonus?
Model a base salary scenario and a salary-plus-bonus scenario, then compare the change in net pay and deductions. Use the annual view to understand the budget impact.
