France: mileage, vehicle expenses and tax records
Start with your tax regime
How the local rules work
Your business regime determines how costs are treated. Micro-BIC uses a representative expense allowance; other regimes have different expense and vehicle rules.
What to keep
Keep turnover, platform commissions, invoices and professional kilometres. Note your business classification and tax regime before comparing methods.
What the odometer message means
The app needs total vehicle distance, including personal driving, to estimate business use. Enter beginning and ending odometer readings for the same vehicle and reporting period. Missing total distance means the percentage is incomplete; it does not erase your recorded business trips.
80% business · 20% personal
12,000 ÷ 15,000 × 100 = 80%. Use miles or kilometres consistently. This is a usage ratio, not automatic permission to deduct 80% of every cost.
Avoid this mistake
Do not apply an employee mileage table or BNC vehicle method to every rideshare business. An expense allowance and a separate actual-cost claim are not interchangeable.
