A PAYE tax refund is money returned to you when you've paid more tax than you should have. The Irish PAYE system deducts tax from your salary at source, but various factors can cause you to overpay:
- •Tax credits not applied correctly
- •Emergency tax when starting a new job
- •Unclaimed tax reliefs and expenses
- •Only working part of the year
Common Reasons for PAYE Refunds
1. Emergency Tax
When you start a new job without proper tax registration, you're charged emergency tax at up to 52%. Once resolved, you can claim back the overcharge. Emergency tax refunds are often the largest - ranging from hundreds to thousands of euros.
2. Unclaimed Tax Credits
Many tax credits must be actively claimed:
| Tax Credit | 2025 Value |
|---|---|
| Rent Tax Credit | Up to €1,000 |
| Single Parent Child Carer Credit | €1,900 |
| Home Carer's Tax Credit | up to €1,950 |
3. Medical Expenses
You can claim 20% tax relief on qualifying medical expenses including GP visits, prescriptions, dental treatment, physiotherapy, and more.
4. Flat Rate Expenses
Many occupations qualify for flat rate expense deductions - automatic allowances that reduce your taxable income. Nurses (€733), teachers (€518), and gardaí (€518) are among the highest.
5. Working From Home
If you work from home, you can claim 30% tax relief on electricity, heating, and broadband proportionate to your work-from-home time.
