The problem: two reference dates, two tax events
When acquiring shares in a real-estate-holding company, signing and completion regularly fall apart: on the day of Signing, the share purchase agreement is concluded; Closing — the proprietary transfer of the shares — often follows weeks or months later, for example because merger clearances or financing conditions must first be satisfied.
This is explosive under real estate transfer tax law. Signing alone can already satisfy the share consolidation event (Section 1 (3) No. 1 GrEStG), because the obligatory transaction is sufficient. Closing then additionally triggers the change of shareholder event under Section 1 (2a) or (2b) GrEStG. One economic transaction — two tax events, both in principle taxable.
The statutory response: Section 16 (4a) GrEStG
The legislature identified the problem and created a correction provision in Section 16 (4a) GrEStG: the assessment issued at signing under Section 1 (3) GrEStG is, on application, cancelled or amended when the change of shareholder at closing is taxed under Section 1 (2a) or (2b) GrEStG. The result — as it should be — is a single tax burden.
The Achilles heel: notification obligations
The correction has a catch, found in Section 16 (5a) GrEStG: it requires that both events — signing and closing — have been notified on time and in full (Sections 18 to 20 GrEStG). The notification period is generally only two weeks, and one month for certain parties. Anyone who misses the deadline, files an incomplete notification, or submits it late risks the double assessment standing — the tax then falls due twice.
This is not a theoretical risk: the tax authorities apply these provisions strictly, and the notification under Sections 18 et seq. GrEStG requires detailed information on properties, ownership chains and transactions that can easily be overlooked in the rush of a deal. In multi-tier structures, the risk multiplies with every real-estate-holding company in the chain.
What to do in practice
First: Before any share transaction, clarify whether domestic real estate is directly or indirectly involved — including through ownership chains and even for apparently property-remote target companies.
Second: Prepare the notifications for signing and closing already at the contract drafting stage, and assign responsibility for them clearly — to the adviser rather than the transaction rush. Both notifications must be complete; a correction after the deadline does not cure the defect.
Third: If a double assessment has already been issued, do not accept it: objection, application under Section 16 (4a) GrEStG and — depending on the circumstances — the question of whether the strict notification practice holds in the individual case are all worth examining. This is where structuring meets procedural law: precisely the interface where we work.
