Family Trust for Long-Term Wealth Succession

What advantages, disadvantages and costs come with a family trust and at what level of wealth the long-term preservation and structuring of family assets may become worthwhile.

A family foundation is particularly appropriate where the aim is to keep the assets together in the long term and protect them from access by third parties, where the family accepts that the assets are irrevocably tied up, and where the income significantly exceeds the running costs of the structure. If any of these conditions are not met, the objectives can usually be better achieved using simpler instruments, such as a transfer agreement with a right of usufruct and rights of reclamation. As the foundation has neither shareholders nor heirs, its assets can neither be bequeathed nor sold, pledged or distributed in the event of divorce. Retained income is also subject to corporation tax at 15 per cent plus the solidarity surcharge, and inheritance tax is payable every 30 years.

What are the advantages of a family foundation?

The key advantage is structural in nature: the foundation has neither shareholders nor heirs. Assets transferred to it can no longer be bequeathed, sold, pledged or distributed as part of a matrimonial property settlement. They are shielded from the life risks faced by individual family members. Divorces, insolvencies or business failures affecting individual beneficiaries do not affect the foundation’s assets, as beneficiaries are only entitled to the benefits set out in the articles of association, not to the assets themselves. For entrepreneurial families, there is the added protection against fragmentation: Instead of a growing number of shareholders with diverging interests, a single legal entity permanently holds the shares together – under a governance structure determined by the founder themselves. The business-related variations on this concept are discussed in our article on corporate foundations.

Protection against the founder’s creditors is also a reality, though there is no immediate protection: transfers to the foundation remain vulnerable within the time limits set out in the Act on the Voidability of Transfers – up to four years for transfers made without consideration and up to ten years in cases of deliberate prejudice to creditors. Asset protection through a foundation is therefore only possible as a long-term precaution using unencumbered assets, not as a reaction to an already foreseeable crisis. The same applies to claims to a compulsory share: donations to the foundation are subject to the compulsory share supplement, which is phased out over a period of ten years, meaning that, here too, an early start is decisive for the measure’s effectiveness.

What tax benefits does a family foundation actually offer?

From a tax perspective, a family foundation is no panacea, but in certain circumstances it can offer clear advantages. Retained earnings are subject to corporation tax at 15 per cent plus the solidarity surcharge at foundation level. As long as the foundation is engaged solely in asset management, no trade tax is payable. Dividends from shareholdings in limited companies remain 95 per cent tax-free, subject to the conditions set out in Section 8b of the Corporation Tax Act (KStG). In the case of property assets, there is an additional point that is often underestimated: the asset-managing foundation can sell land tax-free once the ten-year disposal period has expired. A limited liability company (GmbH) acting as an asset manager does not offer this advantage.

This is offset by two tax liabilities that must be factored into every calculation. Firstly, inheritance substitute tax: by law, the foundation’s assets are taxed every 30 years as if they were being passed on to two children. Tax allowances and the exemption for business assets mitigate the tax burden; nevertheless, predictable liquidity is required. Secondly, there is taxation on distributions: payments to beneficiaries are subject to capital gains tax, meaning that assets that have been drawn down are ultimately taxed at two stages. The foundation therefore realises its tax advantages through long-term retention and reinvestment, rather than through ongoing full distribution to the family. Those who wish primarily to transfer assets during their lifetime and make use of tax allowances are often better off adopting the direct gifting strategy described in the article on gift tax.

What are the disadvantages of a family trust?

The most significant disadvantage is its irrevocability. Once recognised, the foundation’s assets are dedicated to the foundation and belong neither to the founder nor to their family. Nor can it be reclaimed. Amendments to the articles of association are only possible within the framework of the reformed foundation law and the foundation’s own articles of association. The purpose and the restrictions on the use of assets are largely set in stone. Anyone wishing to keep open the option of selling the business, using the assets in old age or simply allowing the next generation to change strategy should not set up a foundation.

Added to this are the running costs: The foundation requires a board of directors, accounting records and annual financial statements, tax returns including preparation for inheritance tax, and, from 2026, the maintenance of its entry in the central register of foundations; it is also subject to state supervision of foundations, the intensity of which varies for family foundations depending on regional law. These costs are not one-off items, but are incurred as ongoing expenses across generations – regardless of whether the assets are performing well or poorly. Ultimately, the foundation shifts conflicts rather than resolving them. Disputes amongst shareholders are replaced by disputes over the composition of governing bodies and distribution policy if the articles of association do not contain clear and workable rules on these matters. The quality of the articles of association is therefore the most important factor for success, more important than any tax calculation.

How much does a family foundation cost?

The costs can only be outlined in general terms, as they depend on the size of the assets, the complexity of the foundation and the federal state. When setting up the foundation, costs are incurred for the conceptualisation and drafting of the articles of association by legal and tax advisers. In addition, there may be notary and registration fees for the transfer of property or company shares, the costs of the recognition procedure with the foundation authority, and the costs of declaring the initial endowment for gift tax purposes. On an ongoing basis, there are costs for bookkeeping and annual accounts, tax advice, any remuneration for the board of directors and advisory boards, as well as the administrative costs for maintaining the register.

What matters is not the absolute amount of these items, but their ratio to the sustainable returns on the foundation’s assets. A structure whose administrative costs consume a significant proportion of the annual income is economically ill-conceived – regardless of how elegantly it is structured for tax purposes. Reliable figures for individual cases can only be provided by a detailed cost plan, which we draw up at the start of every foundation project.

At what level of assets is it worth setting up a family foundation?

There is no statutory lower limit, and blanket thresholds are misleading. Instead, a three-stage assessment is a sound approach. Firstly, cost coverage must be guaranteed: the foundation’s ongoing income must consistently exceed its administrative costs by a comfortable margin. Assets consisting mainly of an owner-occupied property or low-yield investments are not viable for a foundation. Secondly, a comparison with the tax-free allowances. If the assets can in any case be transferred tax-free to children and grandchildren within one or two ten-year periods via the gift tax allowances, the foundation creates no additional tax benefit to justify its binding effect. Thirdly, the need for protection: the larger the assets, the more entrepreneurial their structure and the more ramified the family, the greater the importance of protection against fragmentation and continuity, and the more justified the administrative apparatus becomes.

Following this logic, a trust only becomes a viable option for assets that significantly exceed the family’s total tax-free allowances and generate current income on a scale that requires professional management. Below this threshold, transfer agreements, usufruct arrangements and solutions under company law are almost always the better instruments. Our page ‘Wealth Succession and Foundation Law’ provides an overview.

Frequently asked questions about the advantages and disadvantages of a family trust

This makes sense if assets are to be kept together and protected in the long term, the family accepts the irrevocable nature of the arrangement, and the income generated significantly exceeds the running costs. If any of these conditions are not met, transfer agreements incorporating usufruct and rights of recovery are generally the better option.

The disadvantages include the irreversible tie-up of assets, ongoing administrative and advisory costs spanning generations, inheritance tax payable every 30 years, state supervision of the foundation, and the risk of conflicts within governing bodies where the articles of association are unclear. The family is permanently barred from selling or disposing of the assets.

Payments are made exclusively in the form of beneficiary payments as provided for in the Articles of Association, supplemented, where applicable, by appropriate remuneration for duties performed as members of the governing bodies. Such payments are subject to capital gains tax in the hands of the recipient. There is no entitlement to the assets of the fund.

Current income is subject to corporation tax at 15 per cent, plus the solidarity surcharge. No trade tax is payable on pure asset management. Dividends are largely tax-exempt. In addition, there is gift tax upon the establishment of the trust, inheritance substitute tax every 30 years, and taxation of distributions to the beneficiaries.

There is no statutory threshold. The trust is viable if the income comfortably covers its running costs and the assets significantly exceed the family’s tax-free allowance. Below this threshold, direct gifts achieve the same objectives more easily and in a way that is reversible.

No, under the Act on the Voidability of Transfers, transfers remain open to challenge for up to four years, or up to ten years in cases of wilful misconduct. Donations to the trust are subject to the compulsory portion supplement for ten years, with an annual reduction. Asset protection through a trust is a long-term precautionary measure, not a reaction to a crisis.
