A two-founder SaaS company headquartered in Frankfurt, with a US-based product team and EU-routed billing through a German GmbH. After two years of growth, the founders had crossed the threshold where ongoing German trade tax (Gewerbesteuer) plus corporate income tax made the residual after-tax distribution materially smaller than what a Romanian SRL plus relocation would deliver.
The complication was Wegzugsteuer (Germany's exit tax under § 6 AStG): a relocation by the founders without preparation could have crystallised tax on unrealised share gains immediately, in cash, against an asset they had not realised. The mathematics only worked if the move was sequenced.
