How do tax credits translate into actual refund amounts? Understanding this relationship helps you see why certain credits are so valuable—and why missing them can cost you hundreds or thousands of euros.

Our specialists maximise tax credits for every client. Here's how credits affect your refund and why expert review finds more money.

📊 How Credits Work

  • €1 credit = €1 less tax (direct reduction)
  • Personal + Employee: €4,000 base credits
  • Rent credit: Up to €1,000/year
  • SPCCC: €1,900/year

Tax Credits Reduce Tax Directly

Unlike tax deductions, credits reduce your tax bill euro-for-euro. A €1,000 tax credit means €1,000 less tax to pay—regardless of your income level.

This makes credits extremely valuable:

  • Rent credit (€1,000) = €1,000 off your tax
  • SPCCC (€1,900) = €1,900 off your tax
  • Home Carer (€1,950) = €1,950 off your tax

How Unclaimed Credits Create Refunds

If you've been entitled to credits but didn't claim them, you've overpaid tax. When we submit your claim, Revenue refunds that overpayment.

Unclaimed Credit 4-Year Refund
Rent Credit (since 2022) Up to €3,000
SPCCC (4 years) Up to €7,600+
Home Carer (4 years) Up to €7,200

💡 Real Example

Ciara didn't know she could claim rent credit. When we reviewed her tax, we claimed three years of rent credit (€3,000), plus medical expenses (€480) and flat rate expenses (€360). Total refund: €3,840.

Frequently Asked Questions

Do unused credits roll over?

Generally no—tax credits apply to specific years. However, you can claim for up to four past years if you didn't use credits you were entitled to.

What if I don't earn enough to use all credits?

Tax credits can only reduce your tax bill to zero—they can't create a negative (payment to you from nothing). However, any tax you did pay that exceeds what you should have paid gets refunded.

Can married couples share credits?

Yes—married couples and civil partners can allocate credits between them for optimal benefit. Our review ensures credits are arranged efficiently.
