The Irish Tax Hub Income Tax Refund Calculator

Every year, thousands of Irish taxpayers leave money unclaimed. Whether through unrecorded pension contributions (AVCs), unclaimed tax credits, or overlooked medical expenses, Revenue’s system doesn’t automatically catch everything you’re entitled to. That’s where our Refund Calculator steps in - giving you a clear, personalised estimate of how much you may be owed, and putting you on the path to reclaiming it.

This is not just another “rough estimate” tool. It’s the most comprehensive, credit-aware refund calculator in Ireland, built to reflect Revenue’s rules and updated for Budget 2025.

Why Our Refund Calculator Is Different

1. AVCs: The Game-Changer Most Tools Ignore

Many taxpayers don’t realise that Additional Voluntary Contributions (AVCs) can dramatically reduce their tax liability - and in turn, trigger a refund.

Here’s why AVCs matter:

• Reduce your taxable income: AVCs are deducted before income tax, meaning you could get a chunk of your contributions back through reduced liability.
• Unlock refunds on previous years: If your AVCs weren’t fully captured by your employer or Revenue, you can often claim a refund going back up to four years.
• Optimise pension planning: Our calculator lets you model different AVC levels so you can balance today’s net income with tomorrow’s retirement fund.

💡 Scenario:
Sarah earns €70,000 and makes €5,000 in AVCs, but Revenue only captured part of this during payroll. Using our calculator, she can see how the unclaimed AVC reduces her taxable income, triggering a refund of nearly €2,000.

2. All the Major Tax Credits Built In

Unlike generic calculators, ours incorporates the full suite of Irish tax credits, including:

• Personal Tax Credit
• PAYE Credit
• Medical Insurance Relief
• Tuition Fees
• Medical/dental fees
• Home Carer’s Credit
• Rent Tax Credit
• Single Person Child Carer Credit
• Blind Tax Credit

This matters because too many refunds are underestimated when calculators only factor in the basics. With our tool, you see the true impact of every entitlement you may have overlooked.

💡 Scenario:
Mark, a PAYE worker in Dublin, forgot to claim his rent credit for two years. By using our refund calculator, he can simulate the effect of adding the credit, instantly seeing his refund jump by over €1,000.

3. Reliefs That Make a Real Difference

We’ve built in not just credits, but also the reliefs that frequently generate refunds:

• Medical and dental expenses
• Pension contributions (including PRSAs & RACs)

Most calculators don’t allow this level of flexibility. Ours does - because we know your real-life situation is rarely “standard.”

4. Handles Edge Cases with Ease

Our calculator isn’t just for straightforward PAYE workers. It also:

• Accounts for emergency tax (common if you changed jobs or started mid-year)
• Models split-year treatment for those arriving or leaving Ireland
• Captures part-time or multiple job situations where credits may not have been optimised

How the Refund Calculator Works in Practice

1. Input your income and tax paid
2. Add AVCs, pension contributions, and reliefs
3. Select the credits you’re entitled to
4. Get a personalised refund estimate in seconds

From there, you can choose to proceed with Irish Tax Hub, and we’ll:

• Prepare your full claim
• Correspond with Revenue on your behalf
• Chase your refund until it hits your account

Why Over 500,000 Taxpayers Are Missing Out

Revenue doesn’t automatically grant every refund - you need to claim it. That’s why €389 million in refunds went unclaimed last year alone.

Our calculator is designed to:

• Reveal what you’re owed
• Educate you on credits/reliefs you might not know exist
• Show you how AVCs and deductions reduce liability
• Give you confidence to claim back what’s yours

Accuracy

We have a suite of 300 unit tests integrated into our CI pipeline that ensure our calculations are accurate, and verified with a qualified tax consultant (me Damien). All of our calculators use the Budget 2025 figures as their basis.
