Regarding the revocation of the waiver of VAT exemption for supplies of real estate

In its decision of July 2, 2021 (XI R 22/19), the Federal Fiscal Court (BFH) allows the revocation of a waiver under Section 9 (1), (3) sentence 2 UStG of the VAT exemption under Section 4 No. 9 (a) UStG and thus abandons its previous case law. The decision is convincing with regard to the wording and telos of the waiver provision and entails some consequences for practice.
