// rollover and reinvestment structures in german private equity transactions
why rollovers matter
most private equity buyers want founders and management to stay invested. a rollover keeps their interests aligned with the investor. it also reduces the cash the investor has to fund at closing, since part of the purchase price is settled in shares of the acquisition structure.
under german tax law, a rollover can generally be implemented on a tax-neutral basis. it can also be lost years later, long after the deal team has moved on.
two basic routes
cash sale and reinvestment: the seller sells all shares, pays tax on the full gain and reinvests part of the net proceeds. advantage: simple, no holding period, high tax basis in the new shares. the downside: tax is paid on proceeds the seller de facto never receives in cash.
share-for-share exchange: the seller contributes part of the target shares to the acquisition structure in exchange for new shares. under § 21 german reorganization tax act (umwandlungssteuergesetz, umwstg), the rollover can be done at book value, i.e. tax-neutral. this is the standard route where the rollover is material.
small private stakes: for shares held as private assets below the 1% threshold of § 17 of the german income tax act (einkommensteuergesetz, estg) § 20(4a) of that act applies instead of § 21 umwstg. the acquisition costs of the old shares carry over to the new shares without an application, and the seven-year holding period generally does not apply. cash received alongside the new shares is taxed immediately. whether a negotiated management rollover meets the statutory requirements should be assessed case by case.
requirements for a tax-neutral share-for-share exchange
book value treatment under § 21 umwstg grequires, in particular, a receiving corporation in the eu or eea, a majority of voting rights in the target after the contribution, new shares as consideration, other consideration within the statutory limits and a timely application.
three aspects regularly have to be considered carefully:
sequencing: rollover and cash acquisition happen in the same transaction. the closing mechanics should ensure that the receiving company holds the majority when the contribution takes effect.
new shares: the seller must receive shares from a capital increase. an allocation to capital reserves alone is not sufficient.
other consideration: loan notes or cash received alongside the new shares in exchange for the contributed shares count as other consideration. above the statutory thresholds, book value treatment is partially lost. the institutional strip needs to be designed with the rollover in mind.
the seven-year holding period
if the receiving company sells the contributed shares within seven years (or a harmful disposal as set out below takes place), the deferred gain is taxed retroactively at seller level (einbringungsgewinn ii), reduced by one seventh for each full year. this applies to individual sellers/contributors; corporate sellers/contributors are largely outside its scope.
private equity holding periods are typically four to six years. an exit within the lock-up is the base case. the tax is triggered by the investor's decision but generally borne by the seller.
how rollovers get lost after closing
several standard post-closing steps may qualify as a harmful disposal:
mergers in the course of a debt push-down, which the tax authorities generally treat as a disposal
onward contributions from topco to bidco that do not meet the requirements for book value transfers
capital repayments exceeding the book value of the contributed shares
reorganizations to integrate add-on acquisitions
secondary sales, including to continuation vehicles
in addition, the seller must provide annual evidence to the tax office that the contributed shares are still held by the receiving company. the obligation runs for seven years. each year's evidence refers to the anniversary of the contribution and is due by may 31 of the following calendar year. a contribution on october 1, 2026, for example, requires the first evidence by may 31, 2028. if the evidence is not provided, the shares are deemed disposed of as of the relevant anniversary.
a related trap prior to the transaction itself: sellers who contribute their shares into a personal holding company shortly before a sale. if the holding then sells within seven years, the expected benefit largely disappears.
documentation
spa and contribution agreement: sequencing, valuation of the contributed shares and an undertaking by the receiving company to file the application for book value treatment in due time.
shareholders' agreement: investor covenants to avoid triggering events during the lock-up, or a compensation mechanism if they occur. otherwise the seller carries a risk controlled by the investor.
exit provisions: drag-along rights and waterfalls should address the tax cost of an early exit for rolling sellers.
information rights: access to the data needed for the annual evidence and for monitoring reorganizations.
valuation: rollover shares should be issued at the investor's entry price. favorable terms for managers raise wage tax questions.
conclusion
a tax-neutral rollover requires precise structuring at signing. preserving it requires the same precision for seven years after closing.
for sellers, this means contractual protection and reliable annual compliance. for investors, it means accepting constraints on debt push-downs, add-on integration and exit timing. both are best settled in the structure memo and the shareholders' agreement, while each side still has leverage.
