Germany needs a taxation system that satisfies the needs of its citizens while accommodating the corporate sector. The taxation system should give rise to as few unintended behavioural reactions as possible. It should also be fair, clear and feasible. It is particularly important that the taxation system does not distort corporate investment decisions, for capital is highly mobile internationally and even small negative yield differentials can cause outflows.
