Sale of Shareholdings · German Income Tax
Section 17 EStG: German tax on the sale of substantial shareholdings
If an individual sells shares in a corporation, the gain can be taxed in Germany as business income under Section 17 EStG if the individual directly or indirectly held at least 1% of the corporation at any time during the preceding five years. The rule is not limited to German GmbH shares and can also apply to foreign corporations such as a U.S. corporation.
Framework
Section 17 EStG applies to privately held shareholdings that are considered substantial for German tax purposes
Section 17 EStG classifies gains from the sale of certain corporate shareholdings as business income. The shares do not need to be part of an actual business. The provision can also apply to privately held shares once the statutory ownership threshold has been reached.
Typical cases include shareholders of German GmbHs, startup founders and individuals holding significant interests in foreign corporations.
Review
Four issues determine whether Section 17 EStG applies
The tax treatment does not depend solely on the shareholder's percentage on the sale date. Historical and indirect shareholdings can also be decisive.
- individual as seller
- shares in a corporation
- at least 1% ownership during the preceding five years
- sale or a transaction treated as equivalent by law
- direct and indirect interests must be considered
- foreign shareholdings require separate analysis
1% threshold
The ownership percentage on the sale date is not the only relevant percentage
Section 17 EStG generally applies if the taxpayer directly or indirectly held at least 1% of the corporation's capital at any time during the preceding five years.
For example, a shareholder who initially held 10%, later diluted to 0.5% and then sells the remaining shares can still fall within Section 17 EStG because the 1% threshold was exceeded during the five-year period.
Currently 1% or More
The ownership threshold is generally satisfied.
Currently Below 1%
Section 17 EStG can still apply if at least 1% was held during the preceding five years.
Always Below 1%
For privately held shares, the German investment-income rules generally apply instead.
Direct and indirect ownership
Interests held through intermediate entities can also be relevant
The statutory threshold covers both direct and indirect shareholdings. In multi-tier structures, it is therefore necessary to determine what percentage is indirectly attributable to the taxpayer.
For holding structures, family companies and cross-border groups, the complete ownership chain and its historical changes should be documented.
Corporations
Section 17 EStG is not limited to German GmbH shares
The provision can generally apply to shares in foreign corporations if the foreign entity is structurally comparable to a corporation for German tax purposes.
For an ordinary U.S. corporation, corporate classification is usually straightforward. A U.S. LLC, however, can first require a German entity-classification analysis.
Capital gain
The gain is generally sales proceeds less transaction costs and tax basis
The German tax calculation is based on the sales proceeds and the tax basis in the shares. Direct transaction costs connected with the sale can also reduce the gain.
- sales proceeds
- less transaction costs
- less acquisition costs / tax basis
- include later capital contributions
- review additional acquisition costs
- translate foreign-currency transactions separately
Tax basis
The tax basis can change during the life of the investment
Tax basis is not limited to the original purchase price or initial contribution on formation. Later capital increases and certain additional expenses can increase the basis.
Special rules can apply to shareholder loans, guarantees and other forms of loss financing. Whether a loss can create additional acquisition costs depends on the specific structure and the applicable current rules.
Transaction costs
Direct costs of selling the shares can reduce the taxable gain
Expenses directly caused by the sale can generally qualify as transaction costs for purposes of the Section 17 calculation.
Legal Fees
Transaction-specific legal expenses can qualify depending on their direct connection with the sale.
M&A Advisory
Success fees and other directly sale-related advisory costs can be relevant.
Notary & Registry
For German GmbH shares, notarial costs can be directly connected with the transaction.
Partial-income method
Section 17 gains are generally subject to the German partial-income method
For individuals, gains under Section 17 EStG are generally taxed together with the partial-income method. In principle, 40% of the relevant gain is exempt under Section 3 No. 40 EStG, while related deductible expenses are generally limited to 60%.
The taxable portion is subject to the individual's regular progressive income tax rate. The flat 25% German investment-income tax is not the applicable system for a Section 17 gain.
Example
Simplified example
An individual sells a qualifying shareholding for EUR 1,000,000. The tax basis is EUR 200,000 and direct transaction costs are EUR 20,000.
Sales Proceeds
EUR 1,000,000
Gain Before Partial-Income Treatment
EUR 780,000 after deducting EUR 200,000 of tax basis and EUR 20,000 of transaction costs.
Taxable Portion
Generally 60% of the gain calculated under the applicable Section 17 rules.
Special allowance
Section 17(3) EStG provides a limited allowance for smaller gains
A special allowance can apply to gains taxable under Section 17 EStG. The statutory maximum is EUR 9,060 and is adjusted according to the percentage of shares sold.
The allowance is phased out once the gain exceeds a statutory threshold. It therefore normally has little practical relevance for larger business exits.
Partial sale
A sale of only part of the shareholding can also trigger Section 17 EStG
It is not necessary to sell the entire investment. A sale of only part of the shares can fall within Section 17 EStG if the ownership requirements are satisfied.
The tax basis must then be allocated appropriately between the shares sold and the shares retained.
Earn-outs
Variable consideration and earn-outs require separate tax analysis
Business sale agreements frequently include fixed and variable purchase-price components. Additional payments may depend on future revenue, EBITDA, customer retention or other performance measures.
For earn-out structures, it is necessary to determine when and to what extent the additional purchase price is recognized for German tax purposes. It must also be determined whether the payment is truly consideration for the shares or partly compensation for the seller's future services.
Management rollover
Reinvestment in the buyer structure is not automatically tax-neutral
In private-equity and startup transactions, part of the sale proceeds is often reinvested directly into the buyer or a new holding structure. Economically, this can appear to be a “rollover” of the investment.
For German tax purposes, it still has to be determined whether there is first a fully taxable disposal followed by the acquisition of a new investment.
- separate cash consideration and rollover consideration
- document the value of the new shares
- analyze sale and reinvestment separately
- review share-for-share structures
- consider German reorganization tax rules where relevant
Foreign shareholding
A German taxpayer can fall under Section 17 EStG when selling a U.S. corporation
If the seller is subject to unlimited German income tax and owns a qualifying interest in a U.S. corporation, a capital gain is generally part of the German tax analysis.
The fact that the company was formed in Delaware, California, New York or another U.S. state does not prevent Section 17 EStG from applying.
USD / EUR
German tax on a U.S. shareholding is calculated in euros
The acquisition costs and sales proceeds of a U.S. corporation are often denominated in U.S. dollars. For German tax purposes, the relevant amounts must be translated into euros.
The U.S.-dollar gain should not simply be calculated first and then converted at the exchange rate on the sale date. Acquisition and sale transactions are generally reflected using the applicable exchange rates for the respective transactions. Currency movements can therefore become part of the German taxable result.
Double tax treaty
Foreign shareholdings also require a treaty analysis
The fact that a gain is taxable under Section 17 EStG under German domestic law does not by itself determine which country has the treaty right to tax the gain.
For Germany–U.S. cases, Article 13 of the Germany–U.S. tax treaty should be reviewed. Special rules can apply depending on the type of company and the nature of its assets.
U.S. corporation
For ordinary U.S. corporate shares, the taxing right is often allocated to the seller's country of residence
Where a German-resident individual sells shares in an ordinary U.S. corporation, the Germany–U.S. treaty often allocates the capital gain to Germany as the seller's country of residence.
The precise treaty provision should nevertheless be reviewed. Special situations such as real-estate-rich companies, permanent establishments or other specifically covered assets can lead to a different result.
U.S. tax
A German nonresident alien is often not subject to U.S. federal income tax on an ordinary sale of U.S. corporate shares
For an individual resident in Germany who is neither a U.S. citizen nor a U.S. resident alien, ordinary gains from selling U.S. stock are often not subject to U.S. federal income tax under the general domestic rules if no special U.S. tax nexus applies.
This is not universal. U.S. real property interests, a U.S. trade or business, prior U.S. residence or other special rules can require a separate U.S. analysis.
Real-estate-rich companies
U.S. real property interests can trigger special U.S. and treaty rules
If the corporation primarily owns U.S. real estate or the shares qualify as a U.S. real property interest, the ordinary rules for stock sales can be overridden by special U.S. provisions such as FIRPTA.
For real-estate structures, it should therefore not be assumed without further analysis that only Germany can tax the gain.
Capital losses
Section 17 EStG can also apply to losses on substantial shareholdings
Losses from the sale or certain comparable events can generally be relevant for German tax purposes. Loss recognition is, however, subject to specific statutory requirements.
Special analysis can be required for gifted shares, ownership below 1%, later capital transactions, liquidation and insolvency situations.
- document historical ownership percentages
- review whether the shares were purchased or received without consideration
- determine tax basis
- apply the partial-income method
- analyze liquidation and insolvency separately
Liquidation
Dissolution and liquidation can also be relevant under Section 17 EStG
Section 17 EStG is not limited to ordinary share sales. Certain events such as the dissolution of a corporation, capital reductions or distributions from specific equity accounts can have special German tax consequences.
For insolvent or liquidated companies, it is also important to determine when a loss is tax-realized and which acquisition costs can be taken into account.
Gifts and inheritances
Transfers without consideration are not ordinary Section 17 sales
A gift or inheritance of shares is generally not an ordinary sale for consideration under Section 17 EStG. However, the tax basis and historical ownership position can continue to affect the recipient's later sale.
Gift or inheritance tax must also be considered, and cross-border transfers can create additional international tax issues.
Leaving Germany
Section 17 EStG is the foundation for German exit tax on substantial shareholdings
German exit taxation under Section 6 AStG is linked to shareholdings within the scope of Section 17 EStG. The 1% ownership threshold is therefore also highly relevant when planning a move out of Germany.
An actual sale is not required for German exit tax. If the statutory requirements are met, Germany can tax a deemed capital gain upon departure.
Historical ownership
Reducing the shareholding below 1% shortly before a sale does not automatically avoid Section 17 EStG
Because the provision looks back over the preceding five years, reducing the ownership percentage shortly before the sale generally does not eliminate Section 17 exposure.
The complete ownership history should therefore be reviewed before restructurings, gifts or partial sales.
Startups & founders
For founders, Section 17 EStG often becomes economically visible only at exit
A founder often starts with a very high ownership percentage. After several financing rounds, the interest may be diluted substantially, but Section 17 EStG can remain relevant because of the historical ownership percentage.
International startups add further issues such as foreign currency, U.S. corporate law, stock splits, SAFEs, preferred shares and cross-border residence changes.
- document founder shares
- track financing rounds
- record stock splits and conversions
- review vesting and repurchase rights
- document USD acquisition costs
- coordinate treaty and exit-tax issues
Sale before or after moving
The timing of an international move can materially affect the tax result
Where a move into or out of Germany is planned, the expected sale price is not the only relevant factor. It also matters which country is the country of residence when the sale occurs and whether German exit tax was triggered beforehand.
A planned company sale and an international move should therefore be modeled together.
Review process
How a share sale is analyzed under Section 17 EStG
Classify the entity
Determine whether the entity is treated as a corporation for German tax purposes. Foreign entities may require a German entity-classification analysis.
Reconstruct the ownership history
Direct and indirect ownership percentages during the preceding five years are documented.
Determine tax basis
Formation, share purchases, capital increases and possible additional acquisition costs are compiled.
Identify consideration and transaction costs
Fixed purchase price, earn-outs, escrow, holdbacks and transaction expenses are analyzed.
Calculate the capital gain
The gain is determined under Section 17 EStG and, for foreign-currency investments, calculated in euros.
Apply the partial-income method
The partial exemption and corresponding limitation on deductions are taken into account.
Review treaty and foreign tax
For foreign shareholdings, the applicable tax treaty and potential foreign tax exposure are analyzed.
Coordinate exit tax and reinvestment
For international cases, Section 6 AStG, rollover structures and future changes of residence are considered together.
Documents
Documents typically needed for the calculation
Cap Table
Current and historical ownership percentages, including financing rounds.
Share Purchase Agreements
Documents relating to the original acquisition and later share purchases.
Capital Increases
Capital contributions, financing rounds and other basis adjustments.
Sale Agreement

Common mistakes
What is often overlooked under Section 17 EStG
Checking only current ownership
The 1% threshold applies over a five-year lookback period.
Ignoring indirect interests
Indirect shareholdings can also be relevant.
Applying the 25% flat investment tax
Section 17 gains are generally subject to the partial-income method instead.
Incomplete tax basis
Capital increases and certain additional costs can affect the tax basis.
Simply converting the USD gain
Acquisition and sale of U.S. shares must be reflected separately in euros for German tax purposes.
Ignoring the treaty
Foreign shareholdings require an additional review of the allocation of taxing rights.
Misclassifying earn-outs
Variable payments may constitute purchase price or, in part, compensation for future services.
Overlooking German exit tax
A Section 17 shareholding can become taxable under Section 6 AStG before an actual sale occurs.
