German top tax court tightens rules for using private cars on business trips despite having a company car
Executive summary: The Bundesfinanzhof decided that employees entitled to a company car can claim tax deductions for private‑car business trips only under strict prerequisites. The ruling limits a valuable tax benefit, affecting employee net income and prompting firms to revise travel policies and reimbursement systems.
Who is involved: German Federal Finance Court (BFH), Employees with company cars, Employers, Tax advisory firms
Likely next: Companies will update travel and reimbursement guidelines., Tax authorities may issue clarifying guidance., Potential further BFH rulings on related vehicle‑expense questions.
The Bundesfinanzhof ruled that employees who already receive a firm car can only deduct expenses for business trips made in their private vehicle when very narrow conditions are met. The decision sharply curtails a previously common tax‑planning tool and forces both workers and firms to reassess travel reimbursement practices. While the ruling provides legal certainty, it raises the effective tax burden for affected employees and may increase administrative costs for employers.
