Sub-participations in GmbH shares: Federal Fiscal Court provides clarity on taxation
What the ruling means
In its judgment of 19 May 2026 (case no. VIII R 33/24), published on 6 August 2026, the German Federal Fiscal Court (Bundesfinanzhof – BFH) clarified an important procedural question concerning sub-participations in shares in corporations: the bases of taxation are not subject to a separate and uniform determination. This applies irrespective of whether the sub-participation is typical or atypical.
The ruling is relevant in practice because taxation therefore takes place at the level of the individual parties involved. The main participant and the sub-participant must generally report their respective investment income in their individual income tax returns.
No separate and uniform determination of the bases of taxation
The proceedings concerned a sub-participation in a GmbH share. In connection with distributions and the capital gains tax withheld on them, the question arose as to whether the sub-participation could be subject to a separate and uniform determination procedure.
The BFH rejected this. In the Court’s view, there is no statutory basis for such a procedure. In particular, there is no jointly earned income within the meaning of Section 180 (1) sentence 1 no. 2 (a) of the German Fiscal Code (Abgabenordnung – AO). This applies to both typical and atypical sub-participations.
Different tax treatment for typical and atypical sub-participations
Although the BFH reaches the same procedural conclusion for both forms of sub-participation, their tax treatment differs.
Typical sub-participation
In the case of a typical sub-participation, the main participant and the sub-participant derive different types of investment income. While the main participant’s income from the interest in the corporation falls under Section 20 (1) no. 1 in conjunction with Section 20 (5) sentence 1 of the German Income Tax Act (Einkommensteuergesetz – EStG), the sub-participant derives separate investment income under Section 20 (1) no. 4 EStG.
Atypical sub-participation
In the case of an atypical sub-participation, by contrast, the sub-participant is regarded as the beneficial (co-)owner of the share in the corporation and, pursuant to Section 20 (5) sentence 2 EStG, derives investment income within the meaning of Section 20 (1) no. 1 EStG directly.
In both cases, there is therefore no jointly earned income that would allow for a separate and uniform determination.
According to the BFH, such a determination procedure cannot be based on other provisions of the German Fiscal Code either. An analogous application of the relevant provisions is also excluded.
What does the ruling mean in practice?
The judgment makes clear that sub-participations in shares in corporations cannot be dealt with centrally for procedural purposes by means of a separate determination notice. Instead, the relevant income is taken into account for tax purposes at the level of each individual participant.
The correct allocation and reporting of the respective investment income therefore become particularly important. In practice, it should also be checked whether the amounts reported in the individual income tax returns are consistent with the tax certificates issued.
Particularly in the case of more complex participation structures, this may give rise to additional questions requiring coordination, for example regarding the tax classification of the sub-participation or the allocation of the respective investment income.
Reviewing existing participation structures
The ruling provides procedural clarity while at the same time highlighting the importance of correctly classifying sub-participation arrangements for tax purposes.
For existing arrangements, it is therefore advisable to take a closer look at how the income is allocated to the individual participants for tax purposes and whether the corresponding tax certificates are consistent with this treatment.
