For the time being, the German tax advisory and auditing market has been spared a tightening of the ban on third-party ownership. The proposed reform unexpectedly failed in the Bundesrat, leaving the current legal framework intact for now. Anyone interpreting this as a sign that the issue has been resolved should take a closer look. In regulatory matters, postponement is rarely the end of the story. The real question is not whether the third-party ownership ban will return, but when and in what form.
What actually happened
Based on current assessments, the proposal did not fail in the Bundesrat because of the third-party ownership provisions themselves. Instead, the legislative package became entangled in broader political disputes, most notably over the controversial €1,000 bonus payment. In that sense, the third-party ownership rules became collateral damage.
That distinction matters. A proposal that fails because of substantive opposition faces a different political future than one that is delayed for procedural or coalition-political reasons. The political consensus that financial investors’ involvement in tax advisory firms should be subject to tighter restrictions has not disappeared as a result.
Delayed, not defeated
The tightening proposed by the Finance Committee focused in particular on indirect ownership structures, including arrangements involving foreign audit or accounting firms that have long been common in the market. That objective has not changed.
The Bundestag or the Federal Government may still refer the matter to the Mediation Committee in an effort to reach a compromise between the two chambers. In that process, controversial elements of the legislative package could be amended or removed while the proposed third-party ownership restrictions remain intact. It is entirely conceivable that the provisions could return largely unchanged or only slightly modified.
For that reason, it would be misleading to tell investors that the issue is off the table. A more accurate assessment is that the tightening has not entered into force for the moment, but the regulatory risk remains very real. Investors and portfolio companies that take comfort from a different message may find themselves unprepared for developments that could arrive more quickly than expected.
What this means for existing structures
One of the most problematic aspects of the draft legislation from an investor’s perspective was the absence of a clear grandfathering regime and well-defined transitional provisions. That issue remains unresolved.
Even a formal grandfathering provision would provide only limited certainty. Investments evolve. Ownership structures are adjusted. Businesses are reorganized. If routine operational changes were treated as creating a new legal situation, any nominal protection could quickly lose practical value. A fund facing an exit within a few years cannot simply wait for lawmakers to provide clarity at some undefined point in the future.
The practical consequence is straightforward. Investors who leave existing structures untouched because the reform has stalled may be underestimating the risk. Existing investments should be reviewed carefully, including ownership chains, governance arrangements, veto rights, control rights, and profit participation mechanisms. Ongoing transactions should be examined for regulatory change provisions, termination rights, and adjustment mechanisms. New structures should not be built on the assumption that the current legal framework will remain unchanged indefinitely. That is a bet investors may ultimately lose.
Uncertainty is the real burden
At present, uncertainty is creating more disruption than the legislation itself would.
Legal uncertainty carries its own economic cost. Buyers become more cautious. Financing providers conduct deeper reviews. Valuations come under pressure because market participants cannot reliably predict which ownership models will remain viable in the future.
Closing risk therefore remains a central transaction issue even without the law taking effect. Structures that remain legally permissible but lose operational flexibility can quickly become less attractive in practice. Governance is no longer merely a compliance issue. It increasingly becomes a test of the economic viability of an investment structure.
Significant legal questions remain open
At the heart of the debate lies a fundamental question. How will influence be defined in the future?
Will the law focus only on formal corporate control, or will economic influence alone be sufficient? The boundary between a permissible capital investment and impermissible control is far from clear. It is likely to require substantial interpretation by regulators and courts. The first wave of relevant case law has yet to emerge.
A European law dimension also remains. Restrictions affecting the freedom of establishment and the free movement of capital may be possible, but only where they pursue legitimate objectives and satisfy proportionality requirements. Whether broad restrictions on third-party ownership are genuinely necessary and proportionate has not been answered by the Bundesrat’s rejection. The question has merely been postponed.
Alternative models will remain relevant
The direction of travel remains clear. Capital may be welcome. Operational control is not.
Therefore, ownership models that separate professional responsibility from commercial platform functions are likely to remain strategically important regardless of when the legislation eventually arrives.
One possible approach would leave the regulated operating entity under the control of licensed professionals, who would retain majority ownership, voting rights, and responsibility for professional decisions. Alongside that entity, investors could own a separate service company performing commercially important functions that do not fall within the protected core of professional activities.
A minority investment in the advisory firm itself could complement such a structure, while the investor’s economic return would be generated through profit participation and revenues at the service-company level.
These structures are legally sophisticated but far from unrealistic. Investors who begin developing sustainable alternatives now will have options that others may only start considering once the law arrives.
Looking ahead
In the short term, caution is likely to continue shaping the market. That is understandable, but it comes at a cost. Every month spent waiting is a month that cannot be used for preparation.
Over the medium term, much will depend on how the Mediation Committee handles the legislative package and in what form the third-party ownership restrictions ultimately re-emerge.
In the longer term, the attractiveness of the German market will depend on the level of flexibility preserved by the final rules. If indirect ownership structures are restricted aggressively, the space available for traditional private equity investment may become very limited. If room remains for differentiated ownership models, an entirely new market landscape could emerge.
The rules have not changed yet. The direction, however, is already visible. The window for forward-looking positioning remains open. Those who use it will be better prepared than those who wait. That was true before the Bundesrat vote, and it remains true today.
