In almost every conversation about wealth management, investors arrive eventually at the same question: what should I buy? That question deserves careful treatment. But beyond a certain portfolio size, it is no longer the most important question. The more important question is: where should I hold what I buy?
That shift sounds unremarkable. In practice it has larger consequences than thirty basis points of fee differential, than a single strong vintage year, or than most asset allocation discussions I have had across sixteen years of market work. This piece attempts to lay out the structural logic behind that claim, not as individual tax advice, but as a framework description. Whether and how this logic applies to your specific situation is a question for your Steuerberater or your specialist tax lawyer. I am neither. I am a wealth manager with CFA and CAIA credentials and several years in a family office. What I describe here is structural knowledge, not an individual recommendation.
What the private depot leaves on the table
The private depot, the standard German brokerage account, is where most investors begin, and where many remain even after their portfolio has reached a scale that justifies more differentiated thinking. Within that structure there are several mechanics that remain systematically underused, even among otherwise sophisticated investors.
The Sparer-Pauschbetrag is the most familiar. One thousand euros per person per year, free from capital gains tax (the amount since 2023). For married couples filing jointly it doubles to two thousand euros. What is underused is not the allowance itself but what I would call the Ehegatten-Hebel, the spousal lever: the ability to structure accounts so that both partners exhaust their allowances fully. In practice I repeatedly see households where the account sits in one name while the other partner records no capital income at all. The second partner's allowance expires year after year, unused. This is not the product of bad intent. It is the product of habit. Habit is expensive in tax terms.
The Teilfreistellung is technically better known, but its practical effect is less intuitively understood. A thirty percent partial exemption applies to distributions and disposal gains from equity fund units, at the investor level. This means only seventy percent of the gain is subject to Abgeltungssteuer. Different rates apply to mixed funds and to real estate funds. The decision whether to hold a direct position or a fund therefore carries a tax dimension through this mechanism, a dimension that should be part of the original allocation decision and usually is not.
The Vorabpauschale is the mechanism most likely to produce unexpected liquidity strain. It is an annual minimum taxation charge on accumulating funds, regardless of whether any distribution has actually been paid. The precise calculation depends on the Bundesbank base rate. For investors holding accumulating funds in any substantial size (very roughly from around fifty thousand euros of fund holdings upward) an annual tax liability accrues that the depot does not service automatically. The custodian draws the amount from the clearing account if a balance exists there. If that balance is insufficient, a forced partial sale can result. This is not an edge case. It is a standard feature of German fund tax law that surprised many investors when it was introduced in 2018 and that still does not appear in every financial plan.
The NV-Bescheinigung, the Nichtveranlagungsbescheinigung, a certificate of non-assessment, is an instrument that remains underused in advised households. It allows individuals who fall below the income tax basic allowance to receive capital income without withholding tax being deducted. It applies frequently to children with their own accounts, to retired family members with modest total income, and sometimes to partners without independent earned income. The administrative burden is low. The compounded effect over years is real. And yet most families never apply for it.
These four mechanics are not loopholes. They are provisions of the law designed to reflect specific economic circumstances. An investor who knows them and incorporates them systematically is not behaving aggressively. He is behaving in an informed way.
The vermögensverwaltende GmbH: structural logic, not a magic instrument
Above a portfolio threshold I would roughly place between five hundred thousand and one million euros (depending on individual circumstances, investment horizon, and the cost structure of the setup) the vermögensverwaltende GmbH enters the conversation as a holding wrapper. I write "enters the conversation" deliberately. It enters as a question to be thought through with a tax adviser, not as an answer.
What is the structural logic? A GmbH that manages financial assets exclusively and carries no operating activity is subject to Körperschaftsteuer and Solidaritätszuschlag on its returns, but not to the personal income tax of the shareholder. The effective tax rate on retained profits therefore sits materially below what an investor with a high marginal personal rate pays in a private depot. That difference is not a detail. It is the mechanism on which the entire analysis rests.
The §8b KStG and the Schachtelprivileg deserve a brief clarification. Where a GmbH holds at least ten percent of the shares in another Kapitalgesellschaft, dividends from that shareholding are ninety-five percent exempt from Körperschaftsteuer. The remaining five percent are treated as non-deductible operating expenses and taxed accordingly. This is a substantial reduction relative to full taxation. It is tied to a shareholding threshold rarely reached in diversified portfolios, but for more concentrated positions, for direct participations, for structures that resemble private equity in their construction, it can become relevant.
The Teilfreistellung also applies at GmbH level for equity fund holdings, under the same basic conditions as in the private depot but on a different tax base, producing a different net result.
What the GmbH structure is not: a solution. It is an instrument. And like any instrument it has limitations that need to be understood before deployment.
The most significant structural constraint is the exit question. Profits retained within the GmbH have been taxed at Körperschaftsteuer rates. When the shareholder wishes to extract those funds (whether as a dividend distribution or as a liquidation proceed) a second level of taxation applies at the natural person level: Abgeltungssteuer plus Solidaritätszuschlag. For those subject to Kirchensteuer, that applies too. The GmbH is therefore not a permanent escape from taxation. It is an instrument of tax deferral and rate arbitrage. The advantage lies in the fact that reinvested after-tax capital compounds on a larger base over long periods, the result of allowing the deferred tax liability to work as an interest-free loan for the duration of the holding period. The disadvantage lies in the second tax event that awaits at exit. An investor who plans the GmbH as a short-term wrapper loses this advantage entirely. An investor with a ten, fifteen, twenty-year horizon and a high marginal rate is looking at a structurally different picture.
The break-even calculation (determining at what portfolio size the GmbH structurally outperforms the private depot, net of setup cost, ongoing accounting, annual audit, tax advisory fees, and exit taxation) cannot be answered in a general form. It depends on portfolio size, income composition, personal tax rate, investment horizon, and intended succession planning. That is not an evasion. It is an honest description of an instrument whose value depends on parameters that differ from case to case.
The limits: §42 AO and the substance requirement
I want to address a point that receives insufficient attention in much writing on this topic, because it is uncomfortable.
§42 of the Abgabenordnung is the general anti-avoidance provision of German tax law. It states, in substance, that a legal arrangement that lacks genuine economic content and is directed exclusively at tax avoidance will be treated for tax purposes as if the simpler, economically obvious arrangement had been chosen instead. The Finanzamt (and in contested cases the Finanzgerichtsbarkeit) assesses whether a structure serves a genuine economic purpose or exists only to circumvent taxation.
This is not a theoretical reservation. It is applied. Structures that can only be explained by reference to their tax effect, and that an independent party would not choose for economic reasons, run the risk of being recharacterised. An investor who establishes a vermögensverwaltende GmbH for strategic, long-term reasons (because he has a long investment horizon, because he plans to accumulate over years, because he wishes to structure a succession) is acting within the law. An investor who establishes one because an adviser told him it "avoids tax", without genuine economic substance behind the choice, is on thin ice.
I describe this boundary not to discourage these structures. I describe it because an informed investor needs to know where the line falls. Tax optimisation and tax avoidance in the sense of §42 AO are different categories. The mechanics described in this piece are legitimate optimisation within applicable law, but only when deployed in a genuine economic context.
The incentive problem that rarely gets named
Why is the structural impact of the holding wrapper on net wealth so rarely the subject of the conversations investors have with their advisers?
My view is that the answer lies in the incentive structure of the industry. An adviser compensated on the basis of assets under management has no financial motivation to move a portion of those assets into a structure that falls outside his mandate. Tax structure optimisation (the decision whether to hold assets in a GmbH, whether to spread allowances across multiple accounts, whether to use gift allowance windows) has no positive AUM effect for the adviser. It sometimes has a negative one, because assets are moved. This is not a moral judgement. It is a structural observation.
The investor who understands this mechanism asks his adviser not only: what should I buy? He also asks: what interest does my adviser have in answering that question the way he answers it? And: who in my advisory network is structurally positioned to ask the second question (where should I hold) at all?
At Kronfeld Kapital, holding structure and tax architecture form a standing part of the Academy curriculum, because I believe that an informed investor asks better questions, and thereby achieves better outcomes, independent of who holds his mandate.
Generational transfer: a brief lateral view
This piece would close incompletely if it ignored the generational dimension entirely (though I will only touch it here, because the subject deserves its own treatment).
The ten-year gift allowance windows (the ability to transfer assets up to statutory thresholds free of gift tax every ten years) are among the most effective instruments of wealth transfer available under German tax law. They produce no spectacular result in any single year. Across three or four decades, across two transfer generations, they accumulate to meaningful amounts. Here again, most households do not use these windows systematically (not because they do not want to, but because no adviser is actively driving the planning).
Foundation structures, Mittelstand succession, the transfer of direct participations in the context of valuation methodologies and depreciation models (these are topics that connect closely to wrapper choice and that I will address in a separate briefing).
The real asymmetry
I return to the opening question. What should I buy? That is the first question. Where should I hold what I buy? That is the second.
The first question is the one for which the majority of advisory mandates are paid. It is not unimportant. But at portfolios that exceed a certain scale, the second question becomes structurally more powerful. The right combination of holding structures (private depot, vermögensverwaltende GmbH, gift allowance planning, systematic use of exemptions) can produce, over ten or fifteen years, an outcome advantage that no fee reduction and no fund manager can replicate.
That is not a criticism of fund management. It is an invitation to widen the frame.
Thirty basis points less in annual fees is real. On a portfolio of one million euros that is three thousand euros per year. Compounded over twenty years, that is a meaningful sum. But structural tax optimisation (the right wrapper decision, the consistent use of allowances, the anticipation of the Vorabpauschale, the correct deployment of Teilfreistellung) operates at a different order of magnitude. It is not visible on an annual statement as a separate line. But it accumulates.
That is the core of this piece. Not: do X or Y. Rather: consider whether the conversational agenda that your current advisory arrangement produces actually addresses the most important questions in your portfolio.
If it does not: that is the asymmetry this piece is naming.
