Same job, lead dev, as a remote gig for a US based entity can generate $150-250k per year. Move the financial operations to a low tax jurisdiction and you ended up with 90% of that liquid. Keep moving around within the residency and taxation limits. Some allow leaving their country for up to a year. Some consider you a tax resident after 90 or 180 days. Lots of ways if the person wants to keep jumping around. To settle, even living in Germany is possible, but not without a GmbH or an UG. The net income will shrink as both the company and the single employee will have to pay relatively higher tax for ass freezing winter and stupid regulations plus amazingly screwed public health insurance.
