Question juridique clé
Whether the book-value uplift on a property contributed to a simple partnership is taxable income.
Solution extraite
Yes. The booked revaluation of business property is income under § 24(1) StG and must be taxed at partner level.
Motifs extraits
The property was business property acquired for resale with profit; the taxpayer himself documented the revaluation and declared it as profit from real estate trading. Taxable appreciation arises upon bookkeeping, not only upon cash realization. The fact that a simple partnership is not itself bookkeeping-bound under civil law is irrelevant for income tax purposes.
