Hello together! A dealer has offered me more discount if I add a commercial license to the purchase of new cars, which I own as a full-time professional (small business operator). Warranty of 24 months remains. 1. Question: How does this affect tax? I pay a gross purchase price. Do I have to specify what? What possibilities are there? 2. Question: Does my private name and not the company’s name stand in the letter? Would you like to use this privately without company contact. 3. Question: Can my company contact me? Son also put his name in the letter without company details? The car is eig. for the son man and it should belong to him if then also right.
