Formula & Methodology Behind the Calculator
The Irish income tax calculation follows a specific sequence of steps that our calculator automates:
Step 1: Calculate Taxable Income
Taxable Income = Gross Income – Pension Contributions – Other Allowable Deductions
Step 2: Apply Income Tax Bands
Ireland uses a progressive tax system with two main rates:
| Tax Band | Single Person (2024) | Married (Joint Assessment) | Rate |
|---|---|---|---|
| Standard Rate | €42,000 | €84,000 | 20% |
| Higher Rate | Balance | Balance | 40% |
Step 3: Calculate Income Tax
Income Tax = (Taxable Income up to band × 20%) + (Remaining Income × 40%) – Tax Credits
Step 4: Calculate Universal Social Charge (USC)
| Income Range | Rate (2024) |
|---|---|
| First €12,012 | 0.5% |
| €12,013 – €22,856 | 2% |
| €22,857 – €70,044 | 4.5% |
| €70,045 – €100,000 | 8% |
| Over €100,000 | 8% |
Step 5: Calculate PRSI
PRSI rates vary by class:
- Class A (Employees): 4% (with income ceiling of €84,080)
- Class S (Self-employed): 4% (no income ceiling)
- Class B/C: Special rates for civil/public servants
Step 6: Sum All Deductions
Total Deductions = Income Tax + USC + PRSI
Step 7: Calculate Net Pay
Net Take-Home Pay = Gross Income – Total Deductions
