Quick Answer
The majority of PAYE workers in Ireland are owed a tax refund at some point in a four-year period. A refund arises whenever the income tax deducted from your wages (under s.112 TCA 1997, Schedule E) exceeds your actual tax liability after all credits and reliefs are applied. The Employee Tax Credit is worth €1,875 in 2025, and the Personal Tax Credit is worth a further €1,875 - if either was not fully applied in any year since 2022, you are likely owed money. Emergency tax, multiple employers, unclaimed medical or WFH expenses, and periods of reduced income are the most common triggers. MyTaxRebate reviews your full history and confirms your entitlement before submitting anything to Revenue - no cost if there is nothing to recover.

Signs You Are Likely Owed a Refund
The simplest diagnostic is to check your payslips and employment history against the criteria below. If any of the following apply to any year since 2022, there is a strong likelihood that a refund is available for that year.
You were placed on emergency tax. Revenue applies emergency tax (a flat 40% deduction) when an employer does not have your full tax credit information at the start of employment. The overpayment from weeks on emergency tax must be actively claimed - any corrective adjustment your employer made applies from the date of correction only and does not automatically refund prior overpayments.
You changed jobs during the year. When you leave one employer and start another, your standard rate band is not automatically transferred to the new employer. For a period, your new employer may deduct tax at the higher rate (40%) on income that should have been taxed at 20%. This generates an overpayment that is recoverable at year-end, but only if you claim.
You had two jobs simultaneously. Revenue assigns your standard rate band (the amount of income taxed at 20%) primarily to your main employer. If a second job is taxed at 40% from the first euro - as often happens when Revenue's records are not updated - the combined tax deducted exceeds your liability and a refund is generated.
You had medical expenses. Out-of-pocket medical costs not covered by health insurance are deductible at 20%. GP visits, prescription medication, physiotherapy, dental procedures, and hospital costs all qualify. If you did not claim these in the year they were incurred, you can claim on a backdated basis.
You worked from home. PAYE employees working from home can claim €3.20 per qualifying workday against utility and broadband costs. If you worked remotely for any period from 2022 onwards and did not claim this relief, it adds to your available refund.
You had a period of lower income. Maternity leave, parental leave, career break, part-time work, or illness all reduce your taxable income. If your tax credits were applied on the basis of a full-year income, a portion of those credits is unused and converts directly into a refund. Unused credits do not carry forward - they must be claimed in the relevant year.
You qualify for flat-rate expenses. Specific occupations (including nurses, teachers, construction workers, retail staff, and many others) are entitled to annual fixed deductions for work-related costs. These do not require receipts and are applied as a percentage or fixed amount against your income. If your occupation qualifies and you did not claim, the relief is available retrospectively.

What Revenue Needs to Process Your Claim
Revenue processes PAYE refund claims based on your income data, deductions, and declared reliefs. For most claims, Revenue holds the income and deduction data directly from employer PMOD submissions. Additional reliefs - medical expenses, WFH costs, rent tax credit - require your declaration and, in some cases, supporting documentation. When MyTaxRebate reviews your position, we access Revenue records with your authorisation, match your employment history against available reliefs, and prepare a complete claim for each applicable year. Revenue then issues a Statement of Liability for each year reviewed and pays any overpayment directly to your bank account.
Starting Your Review: What to Prepare
To begin a PAYE entitlement review with MyTaxRebate, you need your PPS number and a general understanding of your employment history since 2022. Revenue holds the income and deduction data from your employers directly through PMOD, so you do not need to gather payslips for the basic review. For additional reliefs - medical expenses, WFH days, or rent tax credit - we will guide you on what supporting documentation to provide. The review is completed before any claim is submitted, so you know your expected refund before we proceed. There is no cost if no refund is identified.

Tax Scenarios
Emergency tax - new job
A teacher started a new school in September 2023 and was on emergency tax for seven weeks before her credit certificate was issued. The 40% deduction during those weeks generated an overpayment of €940. She also had €620 in qualifying dental costs that year. MyTaxRebate identified both entitlements and submitted a combined 2023 claim for €1,064.
Unclaimed four-year reliefs
An IT professional had worked from home since 2022 and had medical expenses each year but had never claimed. After MyTaxRebate reviewed all four years, the WFH relief (€3.20 per day for around 200 days per year) and medical expenses produced a combined refund of €2,180 across 2022 to 2025.
Changed jobs mid-year
A retail manager left one employer in July 2024 and started a new role in August. Her new employer taxed her income at 40% for the first two months before Revenue transferred her credits. The resulting overpayment was €810 for 2024. MyTaxRebate submitted the claim immediately after year-end and the refund was issued within three weeks. Tip: Even if you're unsure whether a refund applies, a four-year review by MyTaxRebate costs nothing if there is nothing to recover. Starting now ensures you don't lose the 2022 claim year permanently at the end of 2026.
Common Mistakes To Avoid
- ✗Assuming the payslip is correct: Emergency tax and credit misallocations are not visible as errors on a payslip - the deduction appears normal even when it is too high.
- ✗Checking only the current year: The four-year window means you should review 2022, 2023, 2024, and 2025 together - each year is assessed independently.
- ✗Not claiming until you are certain: MyTaxRebate reviews your records before submitting. You do not need to be certain - we determine your entitlement for you.
- ✗Missing the 2022 deadline: The 2022 tax year closes permanently on 31 December 2026. If you are unsure whether you are owed money for 2022, a review now is essential before that window closes.

Frequently Asked Questions
Does Revenue tell me if I am owed a refund?
Revenue does not proactively notify PAYE workers of overpayments. Revenue's PAYE Modernisation system (introduced in 2019) processes payroll in near real-time, but identifying whether all credits were correctly applied - and whether additional reliefs are available - requires a separate review. MyTaxRebate accesses your Revenue records and identifies every entitlement across all four claimable years before submitting anything.
How quickly can I find out if I am owed money?
Once you submit your details to MyTaxRebate, we can typically complete an initial review within a few working days. We review your Revenue records, identify all entitlements, and confirm the estimated refund amount before submitting a claim to Revenue. You do not need to provide extensive paperwork to begin - we access Revenue records directly with your authorisation.
Can I check myself through your Revenue record?
Revenue's your Revenue record system allows you to view your tax credits and submission history. However, identifying all available reliefs, correcting credit allocations across multiple employers, and preparing a consolidated multi-year backdated claim is a complex process that most PAYE workers find difficult to complete correctly without professional guidance. MyTaxRebate handles the full review and claim submission on your behalf.
What years can I claim for in 2025?
In 2025, you can claim for 2022, 2023, 2024, and 2025. Revenue's four-year backdating rule means the oldest claimable year changes annually. The 2022 tax year closes permanently on 31 December 2026 - after that date, no further claims for 2022 can be submitted. Reviewing all four years together maximises your total refund recovery.
Is there a risk that claiming triggers a Revenue audit?
Submitting a legitimate backdated PAYE refund claim does not typically trigger a Revenue compliance intervention. Revenue's PAYE refund process is a standard administrative function. Where claims include additional reliefs such as medical expenses or working-from-home costs, Revenue may request supporting documentation - MyTaxRebate prepares and responds to any such requests on your behalf as part of the service.
