In principle, business meals can be deducted from your taxes. However, there are certain aspects you need to consider.
First of all, you need to take your own part of the bill out of the sum-total. According to the law, 70% of the sum-total of the entertainment bill can be claimed as an expense. It is not necessary to produce an itemised list of individual positions within the bill; rather, it suffices to just take 30% out.
Additionally, the meal always has to have commercial or business grounds.
As an employee, you will have a difficult time convincing the tax and revenue office a meal was business-related, and such claims are rarely recognised. However, if you are self-employed, it is much more convincing to claim that certain meals occurred as part of recruiting potential clients and were, thus, commercially relevant.
Due to the difficulties of justifying entertainment expenses for employees, currently we do not offer a separate field in our tool for the entry of entertainment expenses. If you still wish to claim such expenses, you can attach a free-form annex to your tax return, where you detail your expenses.
