In its two letters dated 1 April 2026, the Federal Ministry of Finance (BMF) has provided fundamental clarifications regarding the VAT group and the adjustment of input VAT deduction in the event of changes in use between taxable activities and non-economic activities in the narrow sense. Those particularly affected are legal entities under public law, non-profit organisations and holding companies. The new administrative interpretation extends the VAT group to non-economic activities. At the same time, it opens up new room to manoeuvre in the case of subsequent changes in use. This has significant implications for the VAT practice.
