No, it’s generally a pretty terrible idea. Germany applies taxes based on the place where a company is managed. If you live in Germany and remotely manage your Estonian company then you’re expected to pay your corporate and other company taxes in Germany. The overhead of managing the international situation is more complicated than opening a company in Germany to be honest
This is insane. So I need to work 5 years on site in Germany as a contractor being paid by foreign parent company, why should the company be liable to be registered and pay taxes in germany. Eg Microsoft sends tech to fix Azure system fir Mercedes.
