French freelance tax deductions: everything you can deduct (and probably forget)
On average, a French freelancer misses 30% of the deductions they're entitled to. This article reviews the most overlooked — and most profitable — categories.
The hole in your declaration
Most freelancers and auto-entrepreneurs in France deduct the obvious: computer equipment, mobile phone, internet subscription. That's a good start. It's also insufficient.
Studies show that on average, a self-employed person forgets about 30% of the deductions they're entitled to. On €50,000 in revenue with €15,000 in potential real expenses, that represents €4,500 in unclaimed deductions — roughly €1,350 in overpaid taxes every year in a 30% marginal bracket.
Over a ten-year freelance career, that's more than €13,000 in fiscal overpayment.
The categories everyone forgets
Home office
If you work from home — even partially — you can deduct a proportional share of your housing costs based on the area dedicated to professional activity. This includes rent or mortgage interest, building charges, electricity and heating, home insurance, property tax, and even a fraction of internet costs.
For a freelancer dedicating 15m² of a 60m² apartment to work, 25% of housing costs are deductible. On rent of €1,200/month including charges, that's €300/month, or €3,600/year in often-overlooked deductions.
Training and professional development
Every investment in skill development is deductible: professional training (certified or not), specialized books and publications, learning tool subscriptions, conferences and seminars (including associated travel costs), professional coaching, and membership in professional organizations.
Banking fees and commissions
Your professional account fees are deductible, but so are payment platform commissions — Stripe, PayPal, Wise — which can represent 2-3% of revenue. On €50,000 in revenue, that's potentially €1,500 in deductions.
Professional travel
Beyond simple client visits, professional travel encompasses mileage allowances (according to the current tax scale), public transport, tolls and parking fees, and vehicle rental for professional assignments.
Communication and marketing
Web hosting, domain names, online advertising (Google Ads, LinkedIn Ads), business card printing, and especially: all your professional SaaS subscriptions. Every tool you use for your business — from Slack to Figma to your CRM — is a deductible expense.
The real cost of approximation
Each category taken in isolation may seem marginal. But it's their accumulation that makes the difference. A rigorous freelancer who exploits all available categories can easily double their deduction amount compared to someone who sticks to the obvious.
The key isn't theoretical knowledge of these categories — it's their systematic application, transaction after transaction, throughout the year. That's precisely where an automatic categorization tool, with 150+ French tax categories, makes the difference between a taxpayer who pays the right amount and one who pays too much.
