The Irish Tax Hub Work From Home Tax Relief Calculator

Since the COVID-19 pandemic, remote working has become the norm for thousands of Irish employees. Whether you’re full-time at home or in a hybrid model, you’ve likely noticed your heating, electricity, and broadband bills rising.

To offset these costs, Revenue allows PAYE employees to claim tax relief on a portion of work from home (WFH) expenses. The rules can be tricky, but in simple terms:

• You can claim 30% of electricity, heating, and internet bills
• The claim is apportioned by the number of days worked from home
• Relief is applied at your marginal tax rate (20% or 40%)
• Any employer daily allowance (up to €3.20/day, tax-free) reduces the claimable amount

While that sounds straightforward, manually calculating it for different years, expense levels, and WFH patterns can be confusing.

That’s why Irish Tax Hub created its Work-From-Home Tax Relief Calculator — an easy-to-use, Revenue-aligned tool that shows exactly what you can claim back.

How the WFH Calculator Works

Irish Tax Hub’s calculator uses the Revenue-approved formula to work out your allowable expenses:

((Annual Bills × WFH Days) ÷ Total Days Worked − Employer Allowance) × 30%

It then applies your marginal rate of tax (20% or 40%) to show your real saving.

What You’ll Enter:

• Tax Year (2021–2025 supported, all Revenue changes accounted for)
• Electricity costs (annual)
• Heating costs (annual)
• Internet costs (annual)
• Days worked from home
• Total annual earnings (to calculate your marginal tax rate)

What You’ll Get:

• A clear breakdown of total claimable relief
• An explanation of how Revenue rules were applied
• The ability to adjust your figures and model different scenarios (full-time vs hybrid WFH, changing utility bills, etc.)

Real-World Example

• Annual electricity: €1,200

• Worked 120 days from home in 2024

His results using the Irish Tax Hub Calculator:

• Total allowable expenses: €312.79
