Remotely working from home

How to calculate allowable remote working costs

You can only claim for the days you worked from home as a remote worker. You cannot include:

  • weekends or public holidays when you did not have to work
  • days you took as annual leave
  • days that you brought work home outside of normal working hours.

Cost shared by more than one person

If the cost is shared between two or more people, it can be apportioned based on the amount each paid.

Calculation formula

Your relief is calculated using the formula ((A × B) ÷ C - D) × 30%, where:

  • (A) is your allowable utility bills for electricity, heating and broadband.
  • (B) is your number of remote working days.
  • (C) is the number of days in the relevant year of assessment.
  • (D) is any remote working allowance reimbursed by your employer.

The relief is given at your highest rate of tax.

  • Example 1

    In 2023, Jane worked from home for 50 days. The cost of her electricity, heating and broadband for 2023 was €1,890. Jane does not receive an allowance for remote working from her employer.

    Calculation of the specified amount for remote working relief

    Description

    		 CalculationAmount

    (A) is the allowable utility bills paid

    		  

    €1,890

    (A) is multiplied by (B) - the number of remote working days

    €1890 × 50

    €94,500

    Divided by (C) - the number of days in the year

    €94,500 ÷ 365

    €258.90

    Deduct (D) - the amount reimbursed by your employer

    0

    €258.90
    Allowable cost (30%) €258.90 × 0.3 €77.67

    Jane pays tax at the higher rate (40%), therefore she will receive €31.07 as tax relief.

  • Example 2

    In 2024, Rob and Mark worked from home in their shared house. They both worked remotely for 181 days. The cost for their electricity and heating for 2024 was €1,200. Their broadband costs were €360. Neither Rob nor Mark received an allowance for remote working from their employer.

    They split the bills equally between them, and each calculate the portion they can claim.

    Amount paid each

    €780

    Multiple by number of remote working days

    €780 × 181

    €141,180

    Divided by 365

    €141,180 ÷ 365

    €386.79

    Allowable cost (30%)

    €386.79 × 0.3

    €116.03

    At the end of the year, Rob and Mark will each complete their own Income Tax Return for 2024. They will each make a claim for costs of €116.03 for remote working relief.

    Rob and Mark both pay tax at the higher tax rate (40%) and will receive €46.41 as tax relief.
