Journeys between home and workplace are tax-deductible with the commuting allowance. In 2014, the former term "regular workplace" was replaced by "primary workplace". The commuting allowance is available to you regardless of the means of transport used. The commuting allowance covers all expenses incurred for travel between home and primary workplace.
The shortest road connection is 9 km and goes through a toll tunnel. An employee wants to save the toll and therefore takes a federal road with a distance of 27 km.
Unfortunately, this employee may only claim a commuting allowance for 9 km as income-related expenses.
