Cars without a trip to the place of work

Hello together, following my problem. I hope you can give me a piece of advice, the first tax consultant could definitely not. Through my employer I have the opportunity to take a company car. In my employment contract a place of work is defined. At this place of work I find myself twice a year, because I am on site with the customer from Monday to Thursday and on Friday always in the home office. In order to minimise the risk of liability, my distance to the first place of business is 45 kilometres, which would correspond to a monetary advantage, at a gross list price of 45,000 euros, of 1057.50 euros. Calculation: 1% per month = 450,00 euros 0.03% to the place of business = 607,50 euros There is now the possibility of 607,50 euros (0.03% * distance to the place of business) from the Finan And does the refund correspond to the same value that will be deducted net to me every month? Example I will be charged 300 euros net and the tax office will return 300 euros net to me at the end of the year? Thank you for your help!
