If you've been working from home since the pandemic began, you could be sitting on a significant tax refund that spans multiple years. Many Irish workers don't realise they can claim work from home (WFH) tax relief not just for the current year, but retrospectively back to 2020. With the standard rate of €3.20 per day and the ability to claim for up to five years at once, this could mean over €1,500 in your pocket. Understanding how to claim WFH relief for multiple years can make a substantial difference to your household finances, especially given the rising costs of electricity and heating.
How Multi-Year WFH Claims Work in Ireland
The Irish Revenue Commissioners allow employees to claim work from home tax relief for any year from 2020 onwards, provided you meet the qualifying criteria. The relief is designed to offset the additional costs of electricity, heating, and broadband that you incur when working from home rather than in your employer's office.
The current rate stands at €3.20 per day for each day you work from home. If you work from home 110 days or more in a year, you'll receive the maximum benefit of approximately €352 per year (based on 110 working days). Importantly, Revenue operates a four-year lookback period for most tax relief claims, which means in 2025, you can claim for 2024, 2023, 2022, and 2021 in a single application.
Calculating Your Multi-Year Refund: Real Examples
Example 1: Full-Time Remote Worker Since 2020
Sarah works completely remotely for a tech company in Dublin. She's worked from home five days a week since March 2020. Here's what her multi-year claim could look like:
- 2020 (from March): Approximately 200 eligible days = €640
- 2021: 220 working days = €704
- 2022: 220 working days = €704
- 2023: 220 working days = €704
- 2024: 220 working days = €704
Total potential refund: €3,456 over the five-year period. At a 20% tax rate, this means approximately €691 back in her pocket, or €1,382 if she's a higher-rate taxpayer at 40%.
Example 2: Hybrid Worker
Michael works three days per week from home, splitting his time between his home office and his company's office in Cork. His situation:
- Per year: Approximately 130 days working from home
- Annual relief: 130 days × €3.20 = €416
- Four-year claim (2021-2024): €1,664 in total relief
As a 40% taxpayer, Michael could receive approximately €665 back from Revenue when claiming all four years together.
Example 3: Occasional Remote Worker
Emma works from home one day per week on average, totalling around 50 days per year. While this is below the 110-day threshold that maximises the benefit, she's still entitled to claim:
- Per year: 50 days × €3.20 = €160
- Four-year claim: €640 in total relief
- Refund at 20% tax rate: €128
Even with fewer days, claiming multiple years makes the effort worthwhile.
Why Claim Multiple Years at Once?
There are several advantages to submitting a multi-year claim rather than claiming year by year:
- Larger lump sum refund: Receiving several years' worth of relief in one payment can make a significant financial difference
- Time efficiency: One comprehensive claim is simpler than multiple separate submissions
- Don't miss out: Claims can only go back four years, so delaying means losing entitlement to earlier years
- Professional handling: Tax professionals can ensure all eligible years are included and maximise your refund
What Documentation You'll Need
When claiming WFH expenses for multiple years, Revenue may require evidence that you genuinely worked from home during the claimed periods. This can include:
- Email confirmation from your employer stating your remote working pattern
- Records of days worked from home (even a simple spreadsheet or calendar)
- Company remote working policies from the relevant years
- Payslips showing your employment during the claimed periods
Professional tax agents understand exactly what Revenue requires and can help compile the necessary documentation to support your multi-year claim, ensuring it's processed smoothly without delays or queries.
Common Mistakes to Avoid When Claiming Multiple Years
Many people inadvertently reduce their refund or face processing delays by making these common errors:
- Underestimating days worked from home: Many people forget to count short periods or occasional remote days
- Not claiming earlier years: Waiting too long means you lose the right to claim 2020, which falls outside the four-year window after 2024
- Incorrect calculations: Small arithmetic errors can reduce your refund significantly over multiple years
- Missing supporting documentation: This can delay your claim by months while Revenue requests additional information
Working with experienced tax professionals ensures your working from home tax relief claim captures every euro you're entitled to across all eligible years.
Frequently Asked Questions
Can I claim WFH relief for 2020 if I haven't claimed it before?
In 2025, you can still claim for 2021, 2022, 2023, and 2024 under the four-year rule. Unfortunately, 2020 claims are generally no longer possible unless you had already initiated the claim process previously. This is why acting now is crucial to protect your entitlement to 2021 relief before it expires.
How long does it take to receive a multi-year refund?
Once Revenue processes your claim, refunds typically arrive within 4-8 weeks, though this can vary depending on the complexity of your tax affairs. Multi-year claims don't necessarily take longer than single-year claims, especially when submitted correctly with all necessary documentation.
What if I only worked from home during certain periods in each year?
You can claim for any days you genuinely worked from home, regardless of whether they were consecutive or spread throughout the year. Many people had changing patterns during 2020-2022 as pandemic restrictions evolved, and you're entitled to claim for whatever days you actually worked remotely.
Can I claim if my employer already pays me a remote working allowance?
If your employer pays you a specific remote working allowance that covers your additional costs, you may not be eligible for the Revenue relief as well. However, many employer allowances don't fully cover costs or weren't in place for all years, so it's worth having a professional review your situation to determine eligibility.
Do I need to claim every year I worked from home, or can I select specific years?
You can choose which years to claim for, though it makes financial sense to claim all eligible years to maximise your refund. There's no disadvantage to claiming multiple years simultaneously, and it ensures you don't leave money on the table.
Don't Leave Money on the Table
Claiming work from home relief for multiple years can result in a substantial tax refund, potentially well over €1,000 for many Irish workers. However, the window for claiming earlier years is closing, with 2021 becoming ineligible after 2025.
The process of calculating eligible days across multiple years, gathering appropriate documentation, and ensuring Revenue accepts your claim can be complex. Small errors or omissions can significantly reduce your refund or lead to frustrating delays.
