An Introduction Page Should Explain the Review Model Clearly
A "why choose us" page is most useful when it explains how MyTaxRebate actually operates rather than relying only on broad reassurance. Readers need to understand what happens after they engage: how the open years are reviewed, how evidence is requested, how Revenue-linked information is used, and how the claim is managed from first review to refund outcome. That operational clarity is what turns a welcome message into a credible service explanation.
It also helps readers understand why the process is broader than one claim form. MyTaxRebate reviews the wider PAYE position so that the worker is not limited to the one issue they already knew about. Framing the introduction around that review model gives the page more substance and makes the choice of provider easier to assess.

Who Is Eligible for a Tax Refund in Ireland?
The statutory basis for recovering overpaid income tax in Ireland is s.865 TCA 1997. This section gives every PAYE worker the right to claim a repayment of income tax that was overpaid in any year within the preceding four years. In 2025, the four open claim years are 2022, 2023, 2024, and 2025.
The core eligibility requirement is straightforward: you paid more income tax in a given year than you were actually liable to pay, and you are claiming within the four-year window. Most PAYE workers who experienced a job change, a career gap, or who work in an occupation with Revenue-approved flat-rate expenses meet this criterion without realising it.
The most common sources of overpayment for PAYE workers in Ireland are: emergency tax during a job change when a new employer operates higher-rate deductions without a Tax Credit Certificate; unused annual tax credits from a period of unemployment; unclaimed flat-rate expense deductions that Revenue approves for dozens of occupations; and qualifying medical expenses paid for yourself or a family member. A four-year professional review identifies all applicable sources simultaneously.
Self-employed individuals manage their tax position through the annual self-assessment return. Workers with a mix of PAYE and self-employed income may still have PAYE overpayments recoverable through the standard mechanism.

Tax Scenarios
Job change in 2023
A worker changed employer in May 2023. The new employer operated emergency tax for three months before a Tax Credit Certificate was issued. Emergency tax of approximately €600 per month above the correct amount produced an overpayment of approximately €1,800 for the three-month period. A claim submitted in 2025 for tax year 2023 recovers this full amount under s.865 TCA 1997.
Nurse with unclaimed flat-rate expenses
A registered nurse who did not claim the Revenue-approved flat-rate deduction of €733 per year across 2022, 2023, 2024, and 2025 is entitled to additional tax relief of €2,932 at the standard rate of 20%, producing a refund of approximately €586. Combined with any emergency tax or credit-related overpayments, the total refund for a nurse over four years through MyTaxRebate is typically €700 - €1,500.
Medical expenses for a child's treatment
A parent paid €2,400 in qualifying medical expenses for a child's orthodontic treatment and specialist consultant fees across 2022 and 2023. At 20% relief, this produces a refund of €480 for those two years. The parent's own GP visits and prescription costs in the same years add a further €180 in relief. Total medical-related refund: approximately €660.
Common Mistakes To Avoid
- ✗Believing that because PAYE was correctly deducted by the employer, there is no refund available. The year-end position can still produce a refund even when each payroll deduction was technically correct, due to unused annual credits.
- ✗Not knowing that flat-rate expenses apply to their occupation. Revenue publishes a full schedule of approved occupations and rates, but many workers are never informed by their employer.
- ✗Assuming the four-year window has already closed. In 2025, claims for 2022 remain open until 31 December 2026.
- ✗Thinking Revenue automatically issues a refund each year. Revenue does not automatically review every PAYE worker's position at year end; a claim must be actively submitted.
