Payslip Validator 2026

How This Tool Works

Enter the figures from your payslip exactly as shown. The tool calculates what your deductions should be based on standard 2026 Irish tax rates, then compares them to what your payslip shows. Differences within a tolerance range are flagged as "Likely Correct" — differences above the tolerance flag as "Check Required" or "Significant Difference".

Why Payslips Sometimes Look Wrong

• Emergency tax: Applied when you start a new job without providing a PPS number or registering with Revenue. Emergency tax can significantly increase your deductions temporarily.
• Week 1 / Month 1 basis: Revenue sometimes puts employees on a non-cumulative tax basis — meaning credits and bands are not accumulated across the year. This can result in higher tax early in the year.
• Different tax credits: If you have additional credits (Rent Tax Credit, medical expenses, disability credits), your deductions will be lower than the default calculation.
• Benefits in Kind: If you receive company car benefit, private health insurance, or other taxable benefits, these are added to your gross pay for tax purposes — your tax may appear higher than expected.
• Multiple employments: If you have two employers, the tax credits and rate band are split between them.

What the Status Means

• Likely Correct: The difference between your payslip and the expected figure is within a 5% tolerance. Minor differences can arise from rounding, exact credit application timing, and other factors.
• Check Required: The difference is notable but could have a legitimate explanation (different credits, week 1 basis, BIK). Check your Tax Credit Certificate and confirm with your payroll department.
• Significant Difference: The difference is large and warrants investigation. Contact your employer's payroll team and, if unresolved, Revenue directly.
