What this Irish Revenue tax calculator helps you do

If you are employed in Ireland, your payslip usually includes three major deductions: Income Tax, USC, and PRSI. This calculator gives you a quick estimate of those deductions and your expected net income, using commonly applied PAYE assumptions.

It is especially useful when you are:

• Comparing two job offers with different salaries
• Planning a pension contribution level
• Checking how marriage tax bands may affect household income
• Estimating monthly take-home pay for budgeting

How Irish employee tax is usually calculated

1) Income Tax

Income Tax is charged at two main rates:

• 20% on income within your standard rate band
• 40% on income above that band

Your available band depends on your tax status (single, married one income, married two incomes). After gross Income Tax is computed, tax credits are applied to reduce the final Income Tax payable.

2) Universal Social Charge (USC)

USC is a separate charge with progressive bands. Lower slices of income are taxed at lower USC rates, then higher slices at higher rates. This calculator applies a common USC band structure and includes the low-income USC exemption.

3) PRSI

PRSI is generally charged as a percentage of pay once minimum thresholds are met. In practice, PRSI classes and credits can vary by employment type; this tool uses a standard employee-style estimate for clarity.

Inputs explained

• Your gross income: Annual salary before tax deductions.
• Tax status: Determines standard rate band and typical tax credits.
• Spouse income: Used only for married two-income calculations.
• Pension contribution %: Treated here as reducing taxable income for Income Tax estimation.
• Additional tax credits: Lets you include known credits beyond basic assumptions.

Worked example (simple)

Suppose your gross salary is €55,000 and you are single with no extra credits and no pension contribution. The calculator first applies Income Tax bands and credits, then adds USC and PRSI. The result is an estimated annual net income and monthly equivalent.

If you then add a pension contribution, you can immediately see how taxable income changes and how that may improve net tax efficiency over time.

Important limitations

This page is a practical estimator, not an official Revenue calculation engine. Real outcomes can differ due to payroll timing, tax class, age-related provisions, medical card treatment for USC, specific reliefs, and payroll software rules.

• Does not replace your Revenue MyAccount records
• Does not include every Irish relief or special case
• Best for planning, not filing

Tips to get a more accurate result

• Use your annualized salary including regular taxable benefits
• Enter realistic pension contribution rates
• Add known credits (if confirmed by Revenue)
• Re-check after Budget updates or Revenue rule changes

Final word

A good Irish tax calculator is not about perfection; it is about making better financial decisions quickly. Use this tool to plan cash flow, compare scenarios, and understand how Income Tax, USC, and PRSI affect your pay. Then confirm final numbers through Revenue or your payroll provider.
