Has someone de-registered (Ab-Meldung) from Germany and moved somewhere else to avoid being considered a tax-resident in Germany (and consequently avoid their company abroad being considered as a German company and having to declare profits)
What is required for that to happen besides leaving your flat rental or cancelling different contracts? (insurances, phone numbers etc)
Do you need to pro-actively inform the fiscal authorities (Finanzamt) , any gotchas?
