Your Phone Bill are among the most overlooked deductions for freelancers — typically deductible at 50–80%, 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 your phone bill 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 monthly invoices and a usage estimate. 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 100% of a single line used for both work and personal calls. 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
A single phone line used for both work and personal use is typically deductible at 50 to 80%. The cleanest setup: a dedicated business line with 100% deductibility — the modest extra cost more than pays for itself in tax savings.
