It is not uncommon for employees to move away from their place of work. Some build or buy a home in the countryside, others move to a more attractive area with better leisure opportunities. Others move out of the marital home and in with a new partner. Single people move to live with their partner in another location. In these cases, you may claim business expenses for additional meal allowances.
If you move your residence away from your place of work to another location and designate your previous flat as a second home, you can now claim meal allowances, even though your meal situation at the place of work has not actually changed. According to the BFH, it is irrelevant for the tax consideration of meal allowances whether there was actually an increased need for additional meals and whether the employee is familiar with the meal situation at the place of work.
