Asset-holding GmbH (vermögensverwaltende GmbH): when does it pay off? Taxes, costs and break-even

In depth12 min read · 12 sources

An asset-holding GmbH (vermögensverwaltende GmbH, a German limited company that manages its own assets) invests money through a corporation instead of a private brokerage account. The appeal: capital gains on shares are almost tax-free within the GmbH, and whatever stays there keeps working without the deduction of flat-rate withholding tax (Abgeltungsteuer). The catch: the tax is due after all when profits are distributed, the GmbH costs money every year, and for ETFs, interest and small dividend holdings it is often more expensive than a private account. Here you can work out when it pays off, as a simplified example and not as tax advice.

The principle: two levels of tax

You set up a GmbH and pay money in, and the GmbH buys shares, funds or bonds. The income is then no longer taxed in your hands but in the company's: with corporation tax, solidarity surcharge and trade tax. As long as the profit stays in the GmbH (retention), that is the end of it. Only when you want money privately does the GmbH make a distribution, and you pay flat-rate tax once more. So the GmbH defers taxes rather than saving them.

Under § 2(2) of the GewStG (2002) (Trade Tax Act), the activity of a corporation counts as a commercial business “always and in full”, even if it only manages a portfolio. The €24,500 allowance on trade income is only available to individuals and partnerships. Take care when contributing an existing portfolio: under § 20(2) sentence 2 of the EStG (2009) (Income Tax Act), even a hidden contribution (verdeckte Einlage) to a corporation counts as a sale. The private book gains are taxed in the process.

Taxes in the GmbH

Corporation tax (Körperschaftsteuer) is 15% for assessment periods up to 2027; after that, under § 23 of the KStG (2002) (Corporate Income Tax Act), it falls by one percentage point a year to 10% from 2032. On top comes a 5.5% solidarity surcharge; the exemption threshold in the SolZG (1993) (Solidarity Surcharge Act) does not apply to a GmbH. Together that is 15.825% today. Trade tax (Gewerbesteuer) is 3.5% of trade income times the municipal multiplier (Hebesatz, § 11 and § 16 GewStG). At a multiplier of 400%, that is 14%, so 29.825% in total. The statutory minimum multiplier rises from 200 to 280% from the 2027 assessment period (§ 16(4) and § 36(5b) GewStG); even in the cheapest municipality, trade tax will then cost 9.8% instead of 7.0%.

What matters is which income is taxable in the first place (CT = corporation tax, TT = trade tax):

Rounded rates with 15% corporation tax, solidarity surcharge and a 400% multiplier; private figures without church tax and without the saver's allowance (Sparer-Pauschbetrag). For shares, 5% of the gain remains taxable as non-deductible expenses: 5% × 29.825% = 1.49%. For an equity ETF: 20% × 15.825% + 60% × 14% = 11.565%.

For capital gains on individual shares, the GmbH is therefore almost tax-free. Dividends from small holdings and interest are actually taxed more heavily in the GmbH than privately. Funds and ETFs do not fall under § 8b KStG, which § 16(3) of the InvStG (2016) (Investment Tax Act) expressly rules out; instead, the partial exemption (Teilfreistellung) for corporations applies, and for trade tax only half of it counts. The Vorabpauschale (advance lump-sum taxation) is also due in the GmbH. And losses on shares are not deductible in the GmbH (§ 8b(3) sentence 3 KStG). That is the flip side of the tax exemption on gains.

Extended deduction: only for real estate

The extended deduction (erweiterte Kürzung) exempts a company from trade tax, but only if it exclusively manages and uses its own real estate, or its own capital assets alongside its own real estate (§ 9 no. 1 sentence 2 GewStG). Only the part of trade income attributable to its own real estate is deducted. A GmbH with a pure securities portfolio therefore does not qualify; a property GmbH with rental buildings then pays only around 15.8% on the rent. The “exclusively” condition is narrow.

Distribution: the second tax

When the GmbH makes a distribution, you as a private individual pay 25% flat-rate tax plus solidarity surcharge (§ 32d EStG (2009)), plus church tax where applicable; the saver's allowance of €1,000 applies here as it does to any investment income. If you hold at least 25%, or at least 1% and work professionally for the GmbH, you can instead apply for the partial income method (Teileinkünfteverfahren): 40% of the distribution is tax-free (EStG § 3 No. 40 2009), and 60% is taxed at your personal rate. The application applies for five years, and the allowance no longer applies. It pays off as long as your marginal tax rate including solidarity surcharge is below 26.375% / 0.6 = 43.96%, for example in low-income years in retirement.

You get your contributions back tax-free: whatever was paid in beyond the share capital (Stammkapital) is recorded by the GmbH in its tax contribution account (steuerliches Einlagekonto, § 27 KStG). However, distributions only reduce this account to the extent that they exceed distributable profit. So profit always counts as distributed first. If the GmbH passes an item of income straight on, the formula above gives:

Without time to retain profits, the GmbH is therefore always worse. Its advantage only arises when income that would be taxed every year in a private account works inside the GmbH for a long time.

Holding structure

Business owners benefit most from the structure: if you hold your operating GmbH through a holding GmbH, its profits flow to the holding as dividends, and with a holding of 15% or more they cost around 1.5% in tax instead of 26.375% privately (§ 8b KStG, § 9 no. 2a GewStG). If the holding invests the money broadly, it becomes an asset-holding GmbH itself. A later sale of the operating GmbH by the holding is also 95% tax-free.

Costs and obligations

• Formation: the articles of association must be notarised (§ 2 GmbHG (1892), the GmbH Act), plus the commercial register entry and a bank account.
• Share capital: at least €25,000 (§ 5 GmbHG); at least half must be paid in before registration (§ 7(2)). The assets needed to maintain the share capital may not flow back to you (§ 30).
• Bookkeeping and annual financial statements under commercial law, corporation tax and trade tax returns, in practice usually with a tax adviser.
• Disclosure: the annual financial statements go to the company register (Unternehmensregister). Micro corporations only have to submit the balance sheet; pure holding companies, however, are expressly excluded from this relief (HGB §§ 267a, 326 2012).
• Chamber of commerce (IHK) fee and charges for the account and portfolio as a corporate client.

In the worked example we assume €2,000 for formation and €4,000 a year. That is an assumption, not a price.

Drawbacks and risks

• Profits are trapped: you can only get at the money privately via distributions, salary or loans, each with its own tax consequences.
• Hidden profit distribution (verdeckte Gewinnausschüttung): benefits the GmbH grants you outside a regular distribution, such as an interest-free loan or an excessive salary, do not reduce its income (§ 8(3) sentence 2 KStG) and are taxable in your hands (hidden profit distribution).
• No offsetting of losses against private assets and no saver's allowance in the GmbH: the company and the shareholder are separate taxpayers.
• Formalities: only the company's assets are liable (§ 13(2) GmbHG), but as managing director you have obligations such as bookkeeping and deadlines.
• Inheritance and gifts: the relief rules for business assets do not apply if administrative assets (Verwaltungsvermögen) make up at least 90% (ErbStG § 13b 2016). In our understanding, a pure securities portfolio is likely to fall into this category. Ask a tax adviser about it.

Worked example: €500,000 over 20 years

A deliberately simplified example: €500,000 starting capital, 7% return a year, 20 years. In the GmbH: corporation tax constant at 15%, multiplier 400%, €2,000 formation costs paid out of the contribution, €4,000 costs a year paid from the portfolio, whose tax effect we ignore. At the end, the GmbH distributes the profit (26.375%), and the contribution comes back tax-free. Privately and in the GmbH: no church tax, saver's allowance or Vorabpauschale.

With other investments, the picture is reversed. Same assumptions; only the type of income changes:

If you buy and hold, you already defer the tax in a private account until the sale. The GmbH then only adds costs and extra tax. With dividends from small holdings, you pay almost the full tax twice.

Break-even: from what level of wealth?

For the favourable case (individual shares with gains realised every year), you can search for the level of wealth at which the GmbH draws level after all taxes. It depends heavily on costs and the holding period:

With €4,000 costs and 20 years, the threshold is around €384,000; with only 5% instead of 7% return, it is €778,627. With a horizon of only ten years, the GmbH with €4,000 costs only pays off from almost a million. With the corporation tax of 10% planned by law (from 2032), the lead in the example grows to €42,439; dividends from small holdings remain clearly at a disadvantage even then (−€308,147).

Simplified example with round assumptions, not tax advice. Costs, the multiplier, the state of the law and your personal situation change the result considerably. Have any specific structure checked individually.

For advanced readers: what the advantage depends on

Roughly, the annual advantage can be written as the tax saving on the realised part of the return, set against the fixed costs:

With r = 7%, q = 1 and a tax difference of 24.88 percentage points, the GmbH saves 1.74% of wealth a year; €4,000 in costs would already be covered from €229,639. The reason the threshold in the example is nevertheless around €384,000 is the distribution: the 26.375% at the end hits the entire increase. The levers are therefore a high share of realised gains (q), a long horizon, low fixed costs and a late or cheap distribution, for example under the partial income method in low-income years. With q = 0 (pure buy and hold), the GmbH can never beat the private account on capital gains, because private tax is then only due at the end anyway.

What the research shows

There are hardly any academic studies on the asset-holding GmbH itself; at its core it is the mechanics of tax deferral. Constantinides (1983) showed that it is optimal to realise losses immediately and gains as late as possible. That is exactly what a private investor who buys and holds already does without a GmbH. The GmbH therefore mainly helps where gains are realised frequently. That frequent trading is itself expensive is shown by Barber and Odean (2000) with data from 66,465 households. The GmbH only lowers the tax, not trading costs or poor decisions.

One rule can be carried over from research on asset location: Dammon et al. (2004) show that tax-inefficient investments such as interest-bearing bonds preferably belong in tax-advantaged accounts. The GmbH, however, taxes interest more heavily than the private account, at 29.825%; in our view, individual shares and large holdings belong in it, while bonds and overnight deposits are better kept as private assets.

Limitations and common mistakes

• Comparing only the tax in the GmbH: 1.5% on share gains sounds like a 25-point advantage, but without the tax on distribution the comparison is skewed.
• Putting ETFs, interest and dividends from small holdings into the GmbH: for an ETF that is bought and held, the private account is around €348,000 better in the example.
• Underestimating fixed costs: below a few hundred thousand euros, the structure does not pay off in the example.
• Assuming the law and the multiplier are fixed: corporation tax changes from 2028, the minimum multiplier from 2027. Over 20 years, the calculation shifts several times.

How Portfolio Lab calculates it

Portfolio Lab's tax module calculates for private investors with a brokerage account in Germany: flat-rate tax with solidarity surcharge and optional church tax, saver's allowance, partial exemption (equity funds 30%, mixed funds 15%, real estate funds 60 or 80%), Vorabpauschale, FIFO and loss offset pots. The app does not calculate GmbH taxation (corporation and trade tax, § 8b KStG, the partial exemption for corporations or the distribution). In the Backtest you calculate the private side with taxes, for example what frequent rebalancing costs; you will need to have the GmbH side calculated outside the app. The overall picture of portfolio, real estate and business holdings is described in total wealth.
