Company cars at 60,000 km “private rides” per year make sense?

Hello Motor-Talk-User, my employer moves my workplace 100 km away from my place of residence (currently 10 km ). Since this annual mileage performance with my current private car is impossible to lift ( about 240.000 km in 4 years ) my employer offers a service car ( incl. private use ). In other words: at 240.000 km in 4 years you would drive your own car “round” // you could buy yourself every 4 years new cars, for this reason the employer offers a How do you calculate the 60,000 km per year private journeys: every day 200 km to the workplace ( back and forth ) x 220 working days = 44,000 km per year. These are so-called private journeys, whereby you could claim advertising costs here at the tax office ?!? The past has shown that I normally drive about 16,000 km privately in the year, so all other journeys like the one to the workplace = 44,000 km to the workplace + 16,000 km purely private = 60,000 km per year. Insured // Church tax payable // Corporate car 30,000 Euro. According to the computer, you earn around 1,800 Euro net // with the above mentioned example with a company car around 1,230 net. However, you could register a wage tax reduction at the tax office, so that my monthly tax burden is reduced. Am I right here with my “account”? What could I do differently, or is it worth a company car? with my calculation example? Unfortunately, find no computer that shows me how much advertising costs (journeys to the workplace ) I could “sell off” monthly. So far I have always submitted the income tax return for the following year, and then “in one stroke” get a refund. Now through a company car and the resulting decidedly lower net wage I would submit an application that I pay monthly in advance less taxes. Or otherwise: with How much MORE net per month could I calculate if I submit this application to the tax office, which would reduce the advertising costs (journeys to the job) monthly my tax burden? Hope I didn’t put myself in a mess… 🙂 Thank you for your answers. VG redpluriel
