Home Office Tax Relief Ireland 2025: What You Can Claim

Reviewed by: MyTaxRebate Team on 11 Mar 2026 | Authority: s.114 TCA 1997 | TDM Part 05-02-13

Quick Answer

Home office expenses claimable by PAYE workers in Ireland via the Revenue e-worker relief are strictly limited to electricity, heating, and broadband. These are claimed at 30% of the total annual cost, apportioned by your WFH day ratio.

For a worker with €3,000 in qualifying annual utility bills working from home 4 days out of 5, the deductible expense is €720 and the tax credit is €144 per year. Under s.114 TCA 1997, all four open years (2022, 2023, 2024, and 2025) can be claimed simultaneously. Rent, mortgage, furniture, and equipment costs do not qualify for the PAYE e-worker relief.

What Home Office Costs Can PAYE Workers Claim?

Revenue's Tax and Duty Manual Part 05-02-13 specifies three categories of qualifying expense for the PAYE e-worker relief: electricity, heating, and broadband. These are intended to cover the incremental costs that arise from working at home rather than in an office - the additional electricity consumed by home equipment, the additional heating of the home during working hours, and the broadband connection used for work.

Home office furniture (desks, chairs, monitors) is not qualifying for the e-worker relief even though it is used for work. Equipment costs may be capital expenses recoverable through different mechanisms, but not through the standard PAYE e-worker claim. Similarly, rent, mortgage interest, and home insurance are not qualifying expenses for PAYE workers under this relief.

Self-employed workers who use part of their home for business can claim a different set of expenses - a proportion of rent (or mortgage interest in limited circumstances), utility costs, and rates - as business deductions in their annual Form 11. This calculation is more complex and uses a different apportionment method. However, these self-employed home expense deductions are entirely separate from the PAYE e-worker relief and cannot be claimed through the PAYE refund mechanism.

How the Employer Allowance Fits In

One of the biggest sources of confusion is the relationship between the Revenue e-worker relief and the employer's optional tax-free daily allowance. These are not the same thing. The employer allowance is a payroll payment made at the employer's discretion. The e-worker relief is a tax deduction calculated from actual qualifying utility costs. A worker can receive the allowance and still have a valid Revenue claim, but the claim must only cover the costs that were not already reimbursed. That is where careful preparation matters.

MyTaxRebate treats this as a coordination exercise rather than a yes-or-no question. We review whether the employer paid nothing, paid the flat daily amount, or directly reimbursed specific bills. We then map that against the utility evidence and the home-working pattern for each year. This avoids the two common errors: assuming the allowance blocks a claim completely, or assuming the same costs can be claimed twice.

Why a Full PAYE Review Often Produces More

A PAYE worker who qualifies for home-working relief often has other PAYE refund items in the same open years. The most common overlap is flat-rate expenses for occupation-specific costs, but medical and dental expenses, rent credit, and job-change overpayments are also common. That is why MyTaxRebate does not treat a WFH article as an isolated claim topic. The better question is not only "what is the e-worker amount?" but "what is the full recoverable refund across all open years once WFH is combined with everything else that legitimately applies?"

In practice, this broader review matters most for workers whose WFH amount on its own looks modest. Someone might only be due a few hundred euro from the utility calculation, but once flat-rate expenses or unclaimed medical relief are added, the four-year total becomes materially more valuable. A professional review prevents those secondary entitlements from being missed simply because the worker started by looking at WFH alone.

Common Errors That Reduce Valid Claims

The recurring mistakes are very consistent: including rent or mortgage costs that do not qualify, forgetting to remove employer reimbursements, using one year's bills for several claim years, or treating an informal choice to work at home as if it were a formal employer-required arrangement. Each of those mistakes can either reduce the true entitlement or create avoidable queries. MyTaxRebate corrects these issues before submission by separating qualifying from non-qualifying costs and matching each year to its own evidence.

Another common error is stopping at the most recent year. Workers often fix 2025 and leave 2022, 2023, or 2024 untouched, even though those years remain open. The result is not a wrong claim, but an incomplete one. A proper four-year review prevents the earliest open year from being missed, which is especially important because the oldest open year is always the one closest to expiry.

Tax Scenarios

Common Mistakes To Avoid

• ✗Confusing the employer €3.20/day allowance with a Revenue claim. The €3.20/day is an optional tax-free employer payment; the e-worker relief is what the employee claims from Revenue.
• ✗Claiming rent or mortgage interest as a qualifying expense. Only electricity, heating, and broadband qualify for the e-worker relief.
• ✗Referencing 2020 as an open claim year. The 2020 and 2021 windows closed permanently on 31 December 2024. The open years in 2025 are 2022, 2023, 2024, and 2025.
• ✗Not claiming because the per-year amount seems modest. Over four years and combined with other reliefs, the total WFH + flat-rate + medical refund frequently reaches €800 - €1,400.
• ✗Including desk, chair, monitor, or other equipment costs in the e-worker relief calculation. Only electricity, heating, and broadband qualify.

When This Does Not Apply

Key Takeaways

• PAYE workers can claim 30% of electricity, heating, and broadband proportionate to WFH days. No other home office costs qualify for this specific relief.
• Rent, mortgage, furniture, and equipment are not qualifying expenses for PAYE e-worker relief.
• All four open years (2022 to 2025) can be claimed simultaneously; the 2022 year closes 31 December 2026.
• Self-employed workers use a different mechanism (Form 11) for home office deductions.
