Determination of the profit threshold for the investment deduction (“Investitionsabzugsbetrag”) (Sect. 7g of the Income Tax Act)

Tax

The question of how to determine “profit” is relevant in several areas of income tax law. In ad-dition to the assessment basis “profit” in Sect. 2(2) sent. 1 no. 1 of the Income Tax Act, such questions arise particularly in Sect. 4(4a) of the Income Tax Act, Sect. 34a of the Income Tax Act, but also with regard to the investment deduction (“Investitionsabzugsbetrag”) of Sect. 7g(1–4), 7 of the Income Tax Act. In this regard, the Federal Tax Court has now ruled that off-balance-sheet adjustments must also be taken into account when determining this “profit threshold”.

Business split-up (“Betriebsaufspaltung”) and trade tax

Business split-up | Trade tax

The business split-up (“Betriebsaufspaltung”) is not regulated by German tax law, but is based on case law. It originally arose with a view to trade tax and its possible erosion when a domi-nant shareholder leases assets to a corporation. In the meantime, it has detached itself from this "context" according to the case law of the Federal Tax Court (“Bundesfinanzhof”) and now has a life of its own that is not enshrined in law. Nevertheless, it continues to have a noticeable impact on trade tax, as a new ruling by the Federal Tax Court (file number IV B 31/25) shows.

Typical silent partnership or atypical silent partnership? Co-entrepreneur yes or no?

BFH-Insights

Sect. 230 et seqq. of the German Commercial Code (“Handelsgesetzbuch”) specify a single "silent partnership". The silent partner participates "in the commercial business operated by another person with a capital contribution" (Sect. 230(1) of the German Commercial Code). From a tax point of view, on the other hand, the details of the articles of association are of utmost importance. Anyone who "builds" a typical silent partnership gets an almost contractual relationship. Anyone who "builds" an atypical silent partnership gets an almost complete income tax co-entrepreneurship (“Mitunternehmerschaft”) with (almost) all positive and negative consequences. The Federal Fiscal Court has now ruled again on the distinction between the two versions of the silent partnership (file number IV R 24/23).

Actual implementation of the profit and loss transfer agreement in the German fiscal unity

Profit and loss transfer agreement

The profit and loss transfer agreement is a "German peculiarity" for establishing a fiscal unity (“Organschaft”) for income tax purposes. It must be concluded for at least five years and implemented throughout its entire term. Unlike other criteria, such as financial integration, there can be no "interruption" in its implementation. If it is not actually implemented, the fiscal unity cannot be established and must be treated as a "failed fiscal unity." The Federal Tax Court has now specified the details of the actual implementation in a new ruling with great practical relevance.
