How many Irish taxpayers claim a tax refund each year?

Revenue publishes annual statistics on tax refunds through its Statistical Report, available on Revenue.ie. Each year, a significant proportion of Ireland's PAYE workers receive some form of tax refund, either automatically through the end-of-year review process or by submitting additional claims through myAccount. The numbers vary by year depending on economic conditions, employment levels, and uptake of new credits such as the rent tax credit introduced in recent budgets. Revenue's annual report provides the most up-to-date figures.

What is the average tax refund amount in Ireland?

The average tax refund in Ireland varies significantly depending on the individual's circumstances, income level, and the number of credits claimed. Taxpayers who claim for four years simultaneously and include credits for medical expenses, rent, tuition fees, and flat-rate expenses can receive substantially higher refunds than the average. Revenue's published statistics report the total value of PAYE refunds issued each year, providing a useful indication of the typical amounts involved. The four-year rule under section 865 TCA 1997 allows most refunds to be maximised.

Which tax credit is most commonly claimed in Ireland?

The personal tax credit and the employee (PAYE) tax credit are the most universally held credits in Ireland, as they are automatically allocated to all taxpayers. Among additional claims made by taxpayers themselves, medical expense relief is consistently among the most frequently claimed, followed by the rent tax credit (since its introduction) and flat-rate expenses for specific occupations. Revenue's annual statistics report provides a breakdown of claims by credit type, showing trends in uptake across the taxpayer population.

Have tax refund amounts increased in recent years in Ireland?

Tax refund amounts in Ireland have generally increased in recent years as new credits have been introduced. The rent tax credit, introduced for the 2022 tax year, added a new entitlement for many private renters. Budget increases to existing credits such as the personal credit and employee credit have also grown over time. Changes to income tax bands and USC rates have further affected the size of refunds. Revenue's annual statistics report, available on Revenue.ie, tracks these trends from year to year for the full PAYE population.

What percentage of PAYE workers in Ireland are owed a tax refund each year?

Revenue's annual statistics indicate that a substantial proportion of PAYE workers in Ireland are owed some form of tax refund each year. The proportion is higher among workers who had changes in their employment status during the year — such as job changes, periods of unemployment, or new children — and among those who actively claim all available credits including medical expenses, rent tax credit, and flat-rate reliefs. Reviewing your myAccount end-of-year statement is the simplest way to determine if you are among those owed a refund.

PAYE Tax Rebate Statistics and Trends in Ireland 2025

Revenue-compliant guidance based on s.865 TCA 1997 (right to repayment of overpaid income tax) and Revenue annual statistics, updated for 2025. Revenue source →

Revenue publishes annual statistics on income tax, PAYE worker numbers, and tax reliefs claimed in Ireland. The data consistently shows that hundreds of thousands of PAYE refund claims are processed annually, with significant sums returned to workers each year. Despite this, an estimated majority of PAYE workers who are entitled to refunds do not claim in any given year, leaving substantial amounts unclaimed across the four-year window available under s.865 TCA 1997. In 2025, the available years are 2022, 2023, 2024, and 2025. Understanding the scale of tax refund activity — and who is claiming — can help workers identify whether they are among those who should be claiming but are not. The average refund processed by MyTaxRebate is €1,100.

Scale of PAYE Refund Activity in Ireland

Ireland has approximately 2.5 million PAYE workers, each potentially entitled to a year-end refund review under s.865 TCA 1997. Revenue processes approximately 350,000 PAYE refund claims per year — roughly 14% of the total PAYE worker population. This means the substantial majority of PAYE workers eligible for a refund review do not submit one in any given year. Given the four-year window, a backlog of unclaimed entitlements builds up annually for these workers. A worker who last reviewed their tax position in 2019 may have four years of unclaimed entitlement in 2025, each representing independent refund calculations.

Medical Expenses: The Most Commonly Claimed Relief

Revenue data consistently shows that medical and dental expense relief (under s.469 TCA 1997) is the most commonly claimed PAYE relief in Ireland. Hundreds of thousands of workers claim this relief annually, reflecting both the prevalence of qualifying expenses and increasing public awareness of the entitlement. Despite this volume, a significant proportion of PAYE workers with qualifying medical expenses still do not claim — either because they are unaware of the relief, believe insurance reimbursement removes the entitlement (it does not, for non-reimbursed amounts), or assume the relief is applied automatically through PAYE (it is not).

Flat-Rate Expenses: Most Consistently Underclaimed

Revenue maintains a list of agreed flat-rate expense allowances for specific occupations (nurses, teachers, construction workers, retail staff, engineers, and dozens of others) under s.114 TCA 1997. These allowances require no receipts — they are agreed by occupation and applied as a fixed annual deduction. Despite requiring no supporting documentation, flat-rate expenses remain consistently the most underclaimed category among eligible PAYE workers. The primary reason is awareness: many workers in qualifying occupations have never heard of the flat-rate allowance that applies to them. Allowances range from approximately €121 per year (retail) to over €1,000 per year (certain specialist occupations).

Remote Working Relief: An Increasing Claim Category

Since Revenue introduced the e-worker (remote working) daily relief in response to changes in working patterns, the volume of remote working claims has increased significantly. The relief provides a daily rate on qualifying home utility costs for days worked from home on a qualifying basis. Workers who worked from home for a significant number of days in 2022, 2023, or 2024 may have an unclaimed remote working relief balance from those years, claimable under s.865 TCA 1997 in 2025.

The Four-Year Backlog Effect

Because the majority of PAYE workers do not review their tax position annually, a significant backlog of unclaimed entitlements accumulates. Under s.865 TCA 1997, this backlog is claimable for four years. Workers who last reviewed in 2020, or never at all, are effectively carrying up to four years of unclaimed refunds. The combination of four years of medical expenses, four years of flat-rate allowances, and any additional credits applicable to their circumstances produces the €1,100 average refund MyTaxRebate recovers across clients. This is substantially higher than a review for any single year alone, because entitlements compound across all available years.

Who Is Most Likely to Be Owed a Refund

The data profile of workers most likely to have an unclaimed refund includes: workers in specific occupations with flat-rate allowances who have never claimed; workers with recurring annual medical or dental expenses who have never claimed; workers who changed employer at any point in the four available years (emergency tax or split credits); workers in joint assessment who qualify for the Home Carer Credit but have not applied; and workers who turned 65 in any of the four available years and have not applied for the Age Tax Credit. These categories collectively represent a large portion of the Irish PAYE workforce.

The Growth in Remote Working Relief Claims

Since 2020, the volume of remote working relief claims has grown significantly as a result of changed working patterns across the Irish workforce. Revenue introduced and formalised the e-worker daily relief to address the widespread shift to home working. Claims for remote working relief continue to be submitted for 2022 and 2023 under s.865 TCA 1997 by workers who worked from home substantially in those years and have not yet claimed the relief. This represents a growing category of unclaimed relief in the backlog of outstanding entitlements, particularly for workers in office-based roles who transitioned to hybrid or full-time home working.

Revenue’s Annual Taxpayer Compliance Data

Revenue publishes annual statistics reports on Irish tax receipts, compliance, and refund activity. These reports confirm the consistent pattern of PAYE overcollection and refund activity across the workforce. Specifically, Revenue data shows that medical expense relief and PAYE year-end balancing consistently account for the largest volumes of individual refund claims each year. The data also shows that the majority of refund claims are for relatively modest amounts — typically under €1,000 per year — but that multi-year claims (covering four years simultaneously) produce the most substantial total refunds. MyTaxRebate’s average of €1,100 reflects the compounding effect of a comprehensive four-year review.

Revenue's annual statistics on Irish taxpayers reveal consistent patterns in how refunds are claimed and distributed across the population. Workers in lower to middle income brackets tend to have higher effective refund rates relative to their income because their personal and employee credits make up a larger proportion of their tax liability. Higher earners, who are more likely to have engaged tax advisers, tend to claim a broader range of credits and reliefs, but their absolute refund amounts can be larger due to the higher marginal rates they pay.

Geographical patterns in tax refund uptake also emerge from Revenue's data. Urban workers in Dublin and Cork, where rental accommodation is most common, have seen higher uptake of the rent tax credit since its introduction. Workers in industries such as healthcare and education, where flat-rate expenses are available, show higher rates of these specific claims than the general workforce. Understanding these patterns helps illustrate that the tax back system under section 865 TCA 1997 is used across all income levels, regions, and employment types in Ireland, and that many workers in every category continue to leave unclaimed refunds that are rightfully owed to them.

Real-World Scenarios

Nurse With Four Years of Unclaimed Flat-Rate Allowance

A staff nurse at a Dublin hospital had never claimed the nursing flat-rate expense allowance (€733 per year in 2025). Over four years, this allowance represents approximately €2,932 in tax deductions, generating approximately €586 in income tax relief at 20%. Combined with four years of qualifying medical and dental expenses (€1,800 total) generating €360 in relief, total four-year refund: €946. The flat-rate component alone accounted for 62% of the total refund.

Teacher With Medical Expenses Across Multiple Years

A secondary school teacher had consistent annual dental and medical costs over four years: €400 in 2022, €620 in 2023, €580 in 2024, and €300 in 2025 to date. Total qualifying expenses: €1,900. Total income tax relief at 20%: €380. He also had four years of the teaching flat-rate allowance (€518 per year, generating €104 per year at 20%) — total €416. Combined with an Age Tax Credit applicable since 2023 (€490 for two years), total refund: €1,286.

Worker Who Never Engaged With Revenue Directly

A retail supervisor aged 45 had never reviewed his tax position. He had worked for the same employer for nine years. When MyTaxRebate reviewed his four-year position, we identified: four years of the retail flat-rate allowance (€121 per year, generating €97 in relief); three years of qualifying medical expenses (totalling €1,400, generating €280 in relief); and one year of remote working relief (60 qualifying days in 2022, generating €124). Total refund: €501. He had never claimed anything previously and had assumed his employer handled everything.

Common Mistakes to Avoid

Assuming that because Revenue processes hundreds of thousands of claims, yours must have been included: Revenue processes claims it receives. If you have not submitted a claim, your entitlements are not in the count. The statistics show the scale of claiming; they do not indicate that all workers have claimed.
Thinking flat-rate expenses are obscure or specialist: Flat-rate expense allowances apply to a wide range of mainstream occupations — retail workers, nurses, teachers, construction workers, engineers, hotel workers, and many others. Most workers in these occupations are entitled to an allowance they have never claimed.
Treating medical expense relief as a one-off rather than annual: If you incur qualifying medical or dental expenses in most years, the relief is a recurring annual entitlement. Not claiming each year (and not backdating through the four-year window) means the cumulative unclaimed amount grows.
Not checking whether remote working relief applies for prior years: Revenue extended the e-worker relief in recognition of widespread home working. Workers who worked from home significantly in 2022, 2023, or 2024 may have an unclaimed relief balance.
Assuming previous reviews covered all categories: A prior review that covered medical expenses only did not cover flat-rate allowances, remote working relief, or additional credits. Each category must be reviewed and claimed specifically.

When This Does Not Apply

Workers who have already reviewed all four available years comprehensively: If a complete four-year review covering all credit and relief categories has been submitted and processed, there is no unclaimed backlog for those years.
Workers who had no qualifying expenses and all credits correctly applied in every year: Where no additional credits were missed and no qualifying expenses were incurred in any of the four available years, there is no refund entitlement.
Tax years outside the four-year window: Under s.865 TCA 1997, years prior to 2022 cannot be claimed in 2025.
Workers who earned below the income tax threshold in all four years: If total income was below the level at which any income tax was owed after credits, there is no income tax to refund.

Key Takeaways

✓ Understand that the majority of eligible PAYE workers do not claim annually — if you have not reviewed your position for four years, significant unclaimed entitlements may exist
✓ Flat-rate expense allowances are the most underclaimed category — check whether your occupation qualifies before assuming you are not entitled
✓ Combine all categories (medical expenses, flat-rate, remote working, additional credits) in a single four-year review for the maximum recovery
✓ The four-year backdating window under s.865 TCA 1997 means the backlog of unclaimed entitlements can be recovered in one comprehensive submission
✓ Submit through MyTaxRebate — we review all categories systematically and file the claim directly with Revenue

Frequently Asked Questions

How many tax refund claims does Revenue process in Ireland each year?

Revenue processes approximately 350,000 PAYE refund claims annually. With approximately 2.5 million PAYE workers in Ireland, this represents roughly 14% of the total PAYE workforce. The substantial majority of eligible workers do not submit a refund review in any given year. Under s.865 TCA 1997, workers who have not reviewed their position for up to four years are able to claim for all outstanding years in a single review.

What is the most commonly claimed tax relief in Ireland?

Medical and dental expense relief under s.469 TCA 1997 is the most commonly claimed PAYE tax relief in Ireland by volume. Hundreds of thousands of workers claim this relief annually. Despite this, a significant proportion of workers with qualifying medical expenses still do not claim — either unaware of the entitlement, incorrectly assuming insurance coverage removes it (it does not for non-reimbursed expenses), or assuming PAYE handles it automatically.

What is the average tax refund in Ireland?

The average tax refund processed by MyTaxRebate across clients is approximately €1,100. This figure reflects the compounding effect of a four-year review covering multiple categories (medical expenses, flat-rate allowances, additional credits, remote working relief). Single-year, single-category reviews typically produce smaller refunds. The four-year simultaneous review under s.865 TCA 1997 is the most effective way to maximise the total recovery.

Why do most Irish workers not claim tax refunds?

The primary reasons most PAYE workers in Ireland do not claim are: lack of awareness (not knowing what they are entitled to or that refunds exist), assumption that PAYE handles everything automatically, belief that the amounts involved are too small to bother with, and unfamiliarity with the Revenue myAccount system. MyTaxRebate exists to address these barriers — we review your position, identify all entitlements, and submit the claim on your behalf with no upfront cost.

How does the four-year rule affect the backlog of unclaimed refunds?

Under s.865 TCA 1997, workers can claim for up to four years simultaneously. Workers who have not reviewed their position for several years accumulate a backlog of unclaimed entitlements — each year representing independent calculations of medical expenses, flat-rate allowances, credits, and other reliefs. The four-year window allows this backlog to be addressed in a single comprehensive review, producing significantly higher combined refunds than any single-year review.
