Abstract
Family offices allocate much of their long-horizon capital to directly held real estate, yet the holding vehicle for cross-border property is usually chosen as a tax-minimization detail rather than analyzed as an investment decision. This study aims to determine whether the choice of governance structure affects the after-tax structural efficiency of cross-border residential real estate investment through the alignment between the structure’s tax treatment and the portfolio’s return composition, rather than through statutory tax rates alone. A stylized counterfactual simulation applies five domestic fiscal regimes (German GbR, asset-managing GmbH, commercial GmbH, Canadian individual ownership, and Canadian CCPC) to each of 42 residential and mixed-use properties (34 in Berlin, 8 in Montreal), using audited accounting data for 2017–2023 and a 2018–2028 horizon; after-tax structural efficiency is measured by input-oriented, variable-returns-to-scale Data Envelopment Analysis estimated separately for each regime on the same 42 properties. Mean scores are 0.9583 (GbR), 0.9477 (Canadian individual), 0.9381 (commercial GmbH), 0.9246 (CCPC), and 0.9183 (asset-managing GmbH); 33 of 42 properties change rank across regimes, with gaps up to 10 percentage points. The ranking contradicts statutory tax burdens: the lowest-taxed structure is the least efficient. A pre-tax capital gains ratio, identical under every regime, moderates the efficiency effect of capital gains taxation (interaction 15.4 percentage points, p = 0.009), and the association strengthens with the tax differential (up to ρ = −0.759). Efficient structure choice therefore depends on the fit between return composition and fiscal treatment, regulatory specificity, rather than on headline rates.
