Company bicycles are not considered a taxable benefit for employees, and employers can deduct their costs from the taxable income, even if they are used for private purposes. Employers can even reimburse € 0,38 per km for business trips made by bicycle. This is a great system that has been ranked as 4 stars, but it could be developed even further.
ECF's recommendations are above all directed at augmenting taxation for company cars, basing it on the purchase price instead than on list price: often companies can get discounts on the overall price for their cars. Furthermore, income tax deduction for commuting should be abolished altogether, or a least be made mode-neutral: when deduction is not linked to the mode of transport, the cheaper one is by far more convenient. This way, walking and cycling to work would be strongly incentivated.
