Quick Answer
If you're fully self-employed in Ireland, you cannot claim the PAYE e-worker tax relief. Instead, you can deduct a proportion of your home utility costs (like electricity, heating, broadband, and potentially rent or mortgage interest) as a business expense when filing your annual Form 11 tax return.
The amount you can deduct depends on the percentage of your home used exclusively for your business, and how much time you spend working there. However, if you are a PAYE worker who also does some freelance work on the side, you can claim the e-worker relief for your PAYE employment while handling your self-employed expenses separately.

How Self-Employed Workers Deduct Home Working Expenses
Self-employed individuals in Ireland calculate their home working expenses differently than PAYE employees. Under section 81 of the Taxes Consolidation Act 1997, you are allowed to deduct expenses that are 'wholly and exclusively' incurred for the purposes of your trade or profession.
To figure out your deduction, Revenue uses an apportionment method. You first need to determine what percentage of your home's total floor area is used exclusively for business purposes (for example, a dedicated home office). Then, you multiply that by the proportion of the day it is used for business. Revenue outlines this in their Tax and Duty Manual Part 04-06-04.
It's important to note that if you work from a space that is also used for personal reasons - like the kitchen table or a corner of your living room - you cannot claim a substantial deduction for that space. Revenue's rules are strict: the space must be used exclusively for business to qualify for a full proportionate deduction.
What If You Have Both PAYE and Self-Employed Income?
Many people in Ireland have a "side hustle" alongside their main job. If you have both PAYE employment income and self-employed freelance income, you have different options for each stream of revenue.
For your PAYE job, if your employer requires you to work from home, you can claim the standard e-worker relief on your PAYE income. This covers 30% of your electricity, heating, and broadband costs, apportioned by your work-from-home days. You can submit this claim through the standard PAYE refund process for the last four open tax years (2022, 2023, 2024, and 2025).
For your self-employed freelance work, you would calculate your home office expenses using the apportionment method described above and deduct them on your annual Form 11 return. You cannot claim the same expenses twice, so you must keep clear records separating the two.
Why Proper Advice Matters for Mixed Income
Navigating the rules between PAYE reliefs and self-employed deductions can get complicated. Claiming self-employed expenses requires keeping detailed records, including proof of the floor area used and the hours worked. Revenue tends to scrutinise these deductions more closely than standard PAYE claims.
While MyTaxRebate specialises in securing maximum refunds for PAYE workers - ensuring you don't miss out on overlapping benefits like flat-rate expenses or medical relief - we always recommend that fully self-employed individuals consult a practicing tax adviser or accountant for their Form 11 returns to ensure their home expense deductions are fully compliant.
Tax Scenarios
Sole trader with a dedicated home office
A freelance designer uses a spare room (10% of the total house floor area) exclusively as an office for 8 hours a day (one-third of a 24-hour day). Their deductible proportion is 10% × 33.3% = 3.33%. If their annual electricity and heating bills total €2,400, their deductible business expense is €2,400 × 3.33% = €80. At the 20% tax rate, this yields a tax saving of €16 per year. If they have a dedicated business broadband line, they can deduct that cost in full.
Working from the kitchen table
A self-employed consultant works from their kitchen table. Because the kitchen is a general household area and not used exclusively for business, they cannot claim a meaningful home expense deduction based on floor area. They can only claim for costs that are clearly 100% business-related, such as a dedicated separate phone line or business broadband.
PAYE worker with a freelance side-business
A marketing manager earns €50,000 from their PAYE job, working from home 3 days a week. They also earn €10,000 freelancing on weekends. They can claim the standard e-worker relief for their PAYE job (e.g., €86/year tax credit) by submitting a four-year claim through MyTaxRebate. They handle their freelance income and any related specific business expenses separately on their annual Form 11 return.
