You are allowed to deduct the travel costs for your way to and from work. For example, the costs of the Swiss public transport pass and a flat rate amount for the bicycle. Under certain circumstances, you may even deduct the costs of the Swiss public transport pass and a car if, for example, you can only reach the station by car. The Confederation and the cantons allow different deductions depending on the means of transport. Other professional expenses that you may deduct as a lump sum or with proof include professional clothing, computers, specialist books and meals away from home.
