Transferring Startup Shares into a Holding: 3 Ways for Founders and Angel Investors (2026)

Founders and angel investors often face the question: how do I subsequently bring my startup shares into a holding GmbH? This guide shows you the three most important ways with all the tax consequences – as of 2026.

Why Subsequently Bring Startup Shares into a Holding?

For founders and investors involved in a startup, there are two main ways to hold shares:

• Private Assets: Holding shares as a private individual
• Holding Structure: Holding shares through an investment holding GmbH or UG

For beginners, holding shares in a German GmbH privately initially appears less complicated. However, from a tax perspective, this variant entails significant disadvantages – especially if sales proceeds from startup exits are to be reinvested. (Detailed pros and cons of a holding can be found here)

A former main argument against holdings – high ongoing administration costs due to annual financial statements – is largely obsolete today. Thanks to modern technology such as the Resolvio platform for holding annual financial statements, costs are now very manageable.

The consequence: Most founders and investors eventually found an investment holding due to the tax advantages. Then the question arises: how do I subsequently bring my existing startup shares into the holding?

Method 1: Contribution via Share Exchange according to Section 21 of the German Reorganization Tax Act (UmwStG)

A share exchange according to Section 21 UmwStG is the most elegant solution from a tax perspective if German GmbH shares are to be contributed without an immediate tax burden.

How the Share Exchange Works

The contribution is made through a contribution agreement. In return, the founder or investor receives new shares in their holding GmbH. In practice, the capital increase with a premium in kind (Sachagio) has established itself as the fastest and most cost-effective variant.

Advantage of Sachagio: Compared to a formation in kind or a capital increase in kind, the complex requirements for a capital increase in kind do not have to be observed.

Frequent Problem: Majority Requirement

The decisive catch with the share exchange: For a contribution at book value – i.e., without taxation of a fictitious capital gain (Section 21 para. 2 UmwStG) – Section 21 para. 1 sentence 2 no. 1 UmwStG requires that the holding company must hold the majority of voting rights (>50%) in the startup GmbH after the contribution (qualified share exchange).

Since angel investors typically only acquire minority stakes, this requirement is usually impossible to meet. Also, with founders who generally found with 2 or more people and distribute shares equally, a majority stake is usually lacking.

Method 2: Contributing a Minority Stake via Voting Rights Design (Section 21 UmwStG)

This solution makes it possible to contribute a minority stake tax-neutrally under Section 21 UmwStG as well. The key lies in the temporary adjustment of the voting ratios.

Basic Principle: Creating a Voting Rights Majority Temporarily

According to Section 21 para. 1 sentence 2 UmwStG, the contribution must only lead to the holding GmbH directly holding the majority of voting rights in the startup GmbH after the contribution of the shares. The voting rights are decisive here, not the capital participation.

Important Note: The majority voting right must be linked to the share and not to the person of the minority shareholder, because the majority voting right must be transferable from the shareholder to the holding.

Practical Implementation: Step by Step

1. Amendment of Articles of Association before Contribution

Before the contribution, the shareholders of the startup GmbH amend the articles of association:

• The share held by the founder or angel investor receives 51% of the voting rights (despite a lower capital participation)
• At the same time, it is specified that all important shareholder resolutions require a 2/3 majority (or unanimity)

Result: The holding receives the voting majority after the contribution (requirement for Section 21 UmwStG), but still cannot decide alone.

2. Implementation of the Contribution

After the amendment of the articles, the tax-neutral contribution of the investment into the holding takes place according to Section 21 UmwStG at book value.

According to the prevailing view in tax law literature, the majority-conferring investment must only exist for one second after the time of the qualified share exchange. The transfer of economic ownership of the contributed shares is decisive, which is regularly the time at which the new shareholder list of the startup GmbH is published in the Commercial Register.

3. Reversing the Voting Rights (Optional)

If the voting majority is lost again after this point in time, this has no effect on the book value continuation. The other shareholders can receive their original voting rights back. It is also possible that another shareholder now receives the majority of voting rights in order to contribute their own minority stake into a holding.

The share exchange triggers the seven-year blocking period according to Section 22 para. 2 UmwStG. According to this, the contributed shares must not be sold by the holding within seven years after the share exchange. However, a change in voting rights is not prohibited.

Tax Advantages of this Design

• Book Value Continuation: No taxation of hidden reserves upon contribution
• No Immediate Liquidity Burden through tax payment
• Long-term Holding Advantages become feasible
• 7-year Blocking Period for book value continuation (Section 22 para. 2 UmwStG)

Requirements for this Design

• Consent of Co-shareholders required for amendment of articles
• Relationship of Trust between shareholders is important
• Careful Documentation of voting rights regulations necessary
• Notarial Certification of the amendment of articles and contribution

Method 3: Contributing a Minority Stake via German UG & Co. KG within the Framework of an Expanded Accrual (Section 20 UmwStG)

This method uses Section 20 UmwStG instead of Section 21 UmwStG and is particularly elegant as it works without the consent of co-shareholders. It is based on the so-called "expanded accrual model" (erweiterte Anwachsung).

Basic Principle: Contribution via Partnership

According to Section 20 UmwStG, tax neutrality can be achieved if a business, part of a business, or co-entrepreneurial share with all essential business assets is contributed to a German GmbH.

The trick: if an investment in a capital company belongs to the business assets of the contributed unit, it is contributed regardless of whether it represents an essential or non-essential business asset and remains tax-neutral.

Practical Implementation: The Three-Stage Process

Step 1: Founding a German UG & Co. KG

The minority shareholder forms a UG & Co. KG together with their holding UG/GmbH as a liability company (general partner GmbH):

• The liability UG/GmbH: 0% profit and asset participation
• The investor as a limited partner: 100% profit and asset participation
• The liability UG/GmbH only receives a fixed fee for assuming liability

Advantage: For this structuring, no consent from other startup shareholders is needed, as it is a private restructuring of the investor.

Step 2: Hidden Contribution of the Minority Stake into the UG & Co. KG

The founder or investor brings their minority stake in the startup GmbH without consideration (hidden contribution) into the UG & Co. KG.

Tax Treatment:

• The contribution of a share within the meaning of Section 17 EStG (from 1% participation) into a partnership is according to Section 6 para. 1 no. 5 sentence 1 letter b EStG always to be valued at acquisition costs
• Therefore, this step is tax-neutral
• Important: The contribution must be made without consideration (no increase in limited partner capital)

Special Business Assets: The founder's or investor's 100% participation in the holding UG/GmbH automatically becomes Special Business Assets II (Sonderbetriebsvermögen II) in the UG & Co. KG.

Step 3: Contribution of the UG & Co. KG into the Holding (Expanded Accrual)

In the final step, the participation in the UG & Co. KG is contributed to the holding in accordance with Section 20 UmwStG against a capital increase.

The Expanded Accrual Model:

• The holding thereby becomes the sole shareholder of the UG & Co. KG
• The UG & Co. KG dissolves (no more shareholders)
• Its assets accrue to the holding (Section 738 BGB analogous)
• Thus, the holding then becomes a shareholder of the startup GmbH

Treatment of Special Business Assets (Holding Shares)

The business assets of the UG & Co. KG also include the special business assets and thus the 100% stake in the holding company.

Problem: Tax neutrality under Section 20 UmwStG can only be achieved if all essential business assets are contributed. Are the holding shares an essential business asset?

Solution according to UmwStE Rz. 20.09:
The shares in the holding can be retained without affecting tax neutrality if an application is simultaneously made whereby the contributor agrees that these shares are to be considered subject to a blocking period.

Consequence: The tax authorities must be proven for seven years annually that the shareholder still holds all shares in their holding. This is usually planned anyway and is therefore not a significant restriction.

Tax Advantages of Expanded Accrual

• Full Tax Neutrality: No taxation upon contribution
• No Consent of Co-shareholders required
• Book Value Continuation according to Section 20 UmwStG
• Long-term Holding Advantages are realized
• 7-year Blocking Period for the holding shares

Requirements and Points to Observe

• Seven-year Proof Obligation: Annual proof of unchanged share ownership in the holding
• Careful Documentation of all steps required
• Tax Guidance by specialist advisors strongly recommended
• Notarial Certifications for formations and contributions

Conclusion and Recommendation for Action: Choosing the Right Strategy

The decision whether and how startup shares should be subsequently transferred to a holding depends on several factors: these include the relationship with co-shareholders, the level of participation, and the development of valuation.
