Maximizing Deductible Business Expenses & Travel Logs
Every legitimate euro spent to operate and expand your business lowers your net taxable profit, directly decreasing your annual income tax liability. However, the Belastingdienst enforces strict boundaries between purely operational business outlays, mixed-use items, and non-deductible personal expenses.
Statutory Mileage Allowance (€0.23/km)
If you use a private vehicle, motorcycle, or bicycle for business trips (client visits, conferences, purchasing office materials), you can deduct a flat tax-free rate of €0.23 per kilometer (effective 2024–2025). You must maintain a compliant travel log (rittenadministratie) documenting the travel date, origin address, destination, purpose, and exact kilometers driven.
