Home Office Expenses are among the most overlooked deductions for freelancers — typically deductible at 10–25%, yet half of self-employed people either skip the claim or document it so weakly that it's reclassified during an audit. Here's how to do it right in 2026.
Why home office expenses qualify
Tax authorities accept this deduction when the expense is necessary for your professional activity, properly documented, and proportional to actual business use. The rule applies in nearly every European country, with national variations on the percentage and threshold.
The document you need
Keep a floor plan with the dedicated work area marked. A bank-statement line alone is not enough — auditors want the source document showing the merchant, the amount, the date and ideally a business justification. Digitize it the day you get it; paper receipts fade in months.
The most common mistake
The single biggest reclassification trigger is deducting the full rent instead of the work-area percentage. It's an honest error in most cases, but the tax authority does not distinguish — the deduction is removed and back-taxes plus penalties apply.
The pro tip
Most countries allow you to deduct rent, electricity, internet and heating proportional to the floor area used exclusively for work — typically 10 to 25% for a freelancer with a dedicated room. Mixed-use spaces (kitchen table) usually don't qualify.
