This is a plain guide to working out your Irish income tax for 2026, written so you can follow each step and check the numbers yourself. Here’s a quick run-through — what to include, where to verify the figures and a euro example you can return to if your pay or situation changes.
Quick reference summary
Use this list to get started fast:
- The basic split is a lower (standard) rate applied up to a band, then a higher rate on the remainder — check Revenue for the exact 2026 percentages that apply to you.
- Most employees pay PRSI at a percentage of reckonable pay — confirm whether you're Class A and what the current percentage and thresholds are on Revenue's site.
- For USC, you apply the relevant rate to each slice of income — whatever the bands are in 2026, treat each band separately and add the results together; verify the exact band limits on Revenue.ie.
- Tax credits: personal tax credit and PAYE credit together typically reduce liability by several thousand euros — check Revenue for exact 2026 amounts.
- Official calculator and guidance: Revenue (https://www.revenue.ie/) and gov.ie tax pages (https://www.gov.ie/).
Prerequisites
Before you start a manual calculation or use an online tool, gather these items:
- Your gross annual income (salary, bonuses, other pay) in euros for 2026.
- Details of pension contributions, PRSI class (usually Class A), and any taxable benefits (company car, VHI paid by employer, etc.).
- List of tax credits you qualify for — personal, PAYE, age or married credits where applicable.
- Details of allowable reliefs: pension reliefs, flat-rate expenses, relief for medical expenses if claiming.
- Access to Revenue online services if you want a machine-checked result: https://www.revenue.ie/.
Step-by-step: build an income tax calculation
Below is a clear, repeatable method for 2026 figures. Go to Revenue.ie and look up your exact credits and bands — that's the only way to be sure the figures match your case.
-
Step 1 — Work out total gross income
Include pay from all employments, bonuses, taxable benefits-in-kind, and any other income subject to PAYE. Example: gross salary €60,000 per year.
-
Step 2 — Deduct allowable items from gross to get taxable pay
Subtract pension contributions (employee), certain professional subscriptions and approved reliefs. If you pay into an Approved Retirement Fund or PRSA, claim relief at source or via return. For the example, assume no pension deduction so taxable pay stays €60,000.
-
Step 3 — Apply the standard-rate band at 20%
The standard-rate band is the portion of your income taxed at 20%. Anything above it's taxed at 40%. Married and single bands differ — verify your band on Revenue’s site. For a single person with a standard-rate band of €40,000: tax at 20% = 0.20 × €40,000 = €8,000.
-
Step 4 — Apply the higher rate at 40%
Tax the remaining income above the band at 40%. Example: remaining €20,000 taxed at 40% = €8,000. Total gross income tax = €8,000 + €8,000 = €16,000.
-
Step 5 — Calculate Universal Social Charge (USC)
USC is separate from income tax. For 2026 the common bands in use are: 0.5% on the first €12,012; 2% on the next slice up to €21,295; 4.5% on the slice up to €70,044; 8% above that. Apply each rate only to the portion in that band. For a €60,000 income the USC would be approximately €1,987 (see worked example below).
-
Step 6 — Calculate employee PRSI
Most employees pay PRSI at 4% of gross pay (Class A). There's a minimum threshold for weekly earnings to be liable in some cases — check Revenue if weekly pay is low. On €60,000 the PRSI would be €2,400.
-
Step 7 — Subtract tax credits
Tax credits cut your tax bill directly — the personal credit and PAYE credit are the usual ones, but make sure you use the exact 2026 amounts from Revenue when you calculate. For 2026 confirm exact credit values on Revenue. In many cases the two credits together are worth around €3,500. Example: €16,000 gross tax − €3,550 credits = €12,450 net income tax.
-
Step 8 — Add USC and PRSI to find total deductions
Add up the tax after credits, the USC and your PRSI so you know the total taken from your pay. Example: €12,450 (income tax) + €1,987 (USC) + €2,400 (PRSI) = €16,837. Net take-home = gross pay − total deductions = €60,000 − €16,837 = €43,163 (rounded).
Worked example (single earner, no children, 2026)
We'll use round figures to keep the arithmetic clear.
- Gross pay: €60,000
- Standard-rate band: €40,000 (taxed at 20%)
- 20% tax on €40,000 = €8,000
- 40% tax on remaining €20,000 = €8,000
- Total income tax before credits = €16,000
- Tax credits (personal + PAYE) = €3,550 → Income tax after credits = €12,450
- USC (approx): 0.5% of €12,012 = €60; 2% of €9,283 = €186; 4.5% of €38,705 = €1,742 → total ≈ €1,988
- PRSI: 4% of €60,000 = €2,400
- Total deductions ≈ €12,450 + €1,988 + €2,400 = €16,838
- Estimated net pay ≈ €43,162
How to use Revenue’s online tools (step-by-step)
- Go to https://www.revenue.ie/ and search for ‘PAYE tax calculator’ or visit the ‘Online Services’ area.
- Open the calculator and select the tax year 2026 if prompted.
- Enter gross pay, pension contributions and any taxable benefits.
- Choose your status (single, married, single parent) so the correct standard-rate band applies.
- Check the tax credits section and tick ones you’re eligible for — the tool will calculate the precise credit amounts.
- Run the calculation and save or print the result. You can also log into MyAccount/ROS for personalised figures: https://www.revenue.ie/en/myaccount/index.aspx.
Costs, fees and eligibility
Here's the thing — using Revenue’s calculators and MyAccount is free. If you hire a tax adviser or accountant expect fees ranging from about €50 for a simple PAYE review to €300–€800 for more complex tax planning or return filing. Companies offering online calculators (accounting firms) sometimes charge for premium features — usually a one-off fee or subscription.
Alternatives and comparisons
There are three common approaches:
- Manual calculation (useful to understand the mechanics and to check payslips).
- Revenue’s official online tools — most accurate for PAYE workers and free.
- Commercial calculators (PwC, Deloitte, tax apps) — handy for scenario modelling (e.g. Salary sacrifice, pension changes), but check the assumptions and fees.
Tips
- Check your standard-rate band — it changes if you’re married or if your spouse/civil partner has income and can transfer band.
- Claim all eligible tax credits — many people miss PRSI credits, age credits or home carer credits.
- Pension contributions reduce taxable pay and can save tax at your marginal rate — they also reduce PRSI and USC in many cases.
- Keep payslips and P60/P45 handy when using an online calculator — small details like a taxable travel allowance change the result.
- Use Revenue MyAccount for a personalised estimate — it knows your employer and recent tax credits.
Common mistakes to avoid
- Using the wrong standard-rate band for your situation — married people often assume the single band applies.
- Forgetting to include benefits-in-kind (company car, medical payments) — they’re taxable.
- Double-counting pension relief — you either claim relief at source or via tax return, not both.
- Confusing USC with income tax — both hit your pay packet but are calculated separately.
- Not updating your tax credits after a life change — marriage, a new job or a child can change entitlements.
For the latest exact rates, bands and tax-credit values for 2026, always check Revenue (https://www.revenue.ie/) and gov.ie. Still, once you’ve got the figures above in front of you, the arithmetic is straightforward and the process repeatable — and this guide will help you verify payslips, plan salary changes or decide whether a salary sacrifice is worth it.
