You have a group structure in which a parent company, as the controlling entity (Organträger), holds a subsidiary as the controlled entity (Organgesellschaft) based on a profit and loss transfer agreement (PLTA). This structure functions efficiently for tax purposes and is widespread among German SMEs. However, the moment a sale is imminent, it becomes clear that this efficiency comes with considerable structural complexity.
What initially appears to be a classic share deal quickly evolves into a challenging issue at the intersection of tax law, corporate law, and transaction practice. The challenge lies less in the sale itself than in the correct temporal and economic classification of the fiscal unity.
Fiscal Unity: Tax Advantage with Structural Ties
Tax fiscal unity allows for the tax consolidation of profits and losses within a group. The profit of the controlled entity is attributed to the controlling entity and taxed there. Prerequisites for this include, in particular, an effective profit and loss transfer agreement and corresponding financial integration.
This construct creates tax efficiency but also leads to close legal and economic ties between the companies. Precisely this entanglement becomes a problem in the transaction context because it complicates a clear separation between the seller's and buyer's periods.
The Central Problem: Timing Between Signing and Closing
In practice, signing and closing rarely coincide. There is often a period of several weeks or months between the contractual agreement and the execution of the transaction. During this time, the fiscal unity continues unchanged.
This means that the controlled entity continues to generate profits which – as long as the profit and loss transfer agreement exists – accrue to the controlling entity. At the same time, it is already clear that the economic allocation of these results will be subject to the transaction.
This is where the actual tension arises: the fiscal unity follows its own logic, while the transaction demands clear economic demarcation.
Termination of Fiscal Unity: No Automatic Process
Fiscal unity does not automatically end with the sale. Rather, the profit and loss transfer agreement must be actively terminated. A distinction must be made between two legally different paths: mutual agreement to terminate and termination – especially for good cause.
The mutual termination of the profit and loss transfer agreement is the standard case. It generally takes place at the end of a fiscal year. The background lies in the tax requirements for fiscal unity according to Section 14 KStG (German Corporate Income Tax Act). Tax recognition requires that the profit and loss transfer agreement be concluded for at least five calendar years and actually implemented during this period. This implementation is tied to full fiscal years.
An intra-year termination would break this system. In such cases, the tax authorities may not recognize the fiscal unity at all – i.e., retroactively – because the minimum term was not properly observed. The consequence would be significant tax corrections, particularly the retroactive denial of loss offsets. For this reason, termination is practically only 'safely' possible at the end of a fiscal year.
Distinct from this is the termination of the profit and loss transfer agreement for good cause. This can also occur intra-year and does not automatically break the tax recognition of the fiscal unity – provided that the good cause is recognized for tax purposes. Such good cause typically exists when the economic basis of the contract ceases to exist, for example, upon the sale of the shareholding in the controlled entity.
However, the demarcation here is not without risk. Not every transaction is necessarily recognized as good cause for tax purposes. Especially in the case of purely planned, economically motivated restructurings, the tax authorities may critically examine whether there is indeed good cause or merely a tax-motivated termination is being sought.
Precisely for this reason, termination is often not relied upon as the sole solution in practice. Instead, the structure is adjusted so that termination is possible at the end of a – possibly shortened – fiscal year. This way, the tax recognition of the fiscal unity can be secured, and a clean transition within the transaction can be ensured.
The Practical Solution: Short Fiscal Year and Clean Cut
To resolve the temporal discrepancy between the transaction and the fiscal year, the structuring of a short fiscal year has become particularly established in practice.
By shortening the fiscal year of the controlled entity, a clearly defined cut-off date is created at which the fiscal unity ends. All results generated up to that point are demarcated and transferred. From this point onwards, there is no longer any profit transfer, and the buyer acquires an economically 'cleaned-up' company.
This approach involves administrative effort, particularly with regard to commercial and tax law coordination. However, it offers a high degree of legal certainty and significantly reduces the risk of later disputes.
The Balance Sheet and Profit Problem in the Closing Year
A particularly sensitive point is the demarcation of results in the year of closing. The profit of the controlled entity until the termination of the PLTA economically accrues to the controlling entity. At the same time, this profit is usually not yet finally determined at the time of closing.
This creates an interim phase in which economic allocation and the actual numerical basis diverge. In practice, this problem is solved through estimates and subsequent settlements. However, this requires that the underlying mechanics are clearly agreed upon.
Purchase Price and Profit Transfer: Economic Allocation
The specifics of fiscal unity directly impact the purchase price structure. The buyer does not acquire the company along with the profits generated up to that point, as these accrue to the seller via the profit and loss transfer agreement.
This economic separation must be reflected in the purchase price. Depending on the structure, this is done via a locked-box mechanism or via closing accounts. It is crucial that there is no ambiguity about which period is economically attributable to the seller and which to the buyer.
The After-Effects of Fiscal Unity
Even after the termination of fiscal unity, legal and economic interdependencies persist.
A central issue is the liability of the controlling entity for the controlled entity's liabilities from the period of fiscal unity. This liability continues for several years and can remain relevant even after the sale.
Furthermore, claims from the profit and loss transfer agreement may remain, for example, in connection with incompletely transferred profits or subsequent corrections. These issues are regularly a subject of disputes in practice if they are not clearly regulated.
Typical Provisions in the Share Purchase Agreement
Against this background, the SPA plays a central role. It must explicitly address the specifics of fiscal unity and translate them into clear regulations.
In particular, it must be stipulated when and how the profit and loss transfer agreement ends and how the results of the current fiscal year are economically allocated. It must also be ensured that this allocation is correctly reflected in the purchase price logic.
In addition, indemnification provisions are required to protect the buyer from liability risks from the period of fiscal unity. Finally, the practical settlement of outstanding claims must also be regulated to avoid future conflicts.
A Real Example: The Holding Company Sale
A family business consists of a holding company as the controlling entity and two operating companies as controlled entities, connected via profit and loss transfer agreements. The founder sells the entire structure to a financial investor.
Legally speaking, the fiscal unity could continue, as nothing changes in the structure. In practice, however, it is often terminated before closing.
The reason is not a legal necessity, but economic considerations. On the one hand, liability risks from the period of fiscal unity persist, which are regularly shifted back to the seller within the framework of the SPA. On the other hand, an ongoing fiscal unity complicates the clear demarcation of results until closing.
In addition, financial investors generally prefer clear structures, free from old entanglements. The termination of fiscal unity therefore creates transparency and reduces complexity.
In practice, a short fiscal year is often introduced, the fiscal unity is terminated before closing, and a final profit demarcation is carried out. The buyer acquires a clear structure without outstanding profit transfer claims.
Practical Tips for Entrepreneurs
Anyone with a fiscal unity in a sales process should start structural planning early. The timing of the termination of fiscal unity is crucial and cannot be 'fixed' at short notice.
Equally important is clean documentation of profit transfers and loss compensations over the entire term of the fiscal unity. This information is regularly subject to due diligence and forms the basis for purchase price determination.
On the buyer's side, it is advisable to examine the history of the fiscal unity in detail. Incomplete or incorrect transfers can have significant economic consequences.
Last but not least, a deep understanding of the purchase price mechanism is required. The allocation of results between seller and buyer is complex in existing fiscal unities and should be understood in detail.
Conclusion: Master Complexity Instead of Avoiding It
Fiscal unity is a powerful tax instrument that, however, poses special requirements in the sales process. Its complexity is manageable – provided it is integrated into transaction planning early and structured cleanly.
Those who coordinate timing, documentation, and contractual arrangements can leverage the advantages of fiscal unity while controlling its risks. This is precisely the difference between a formally concluded and an economically successful transaction.
