The VAT treatment of construction and renovation of real estate is complex – particularly when financing is provided through grants or when there are activities that consistently operate at a deficit. The Federal Fiscal Court (judgment of July 9, 2025, XI R 32/22) clarifies: The decisive factor for input VAT deduction is the taxable person’s objectively documented intention of use, not the type of financing or profit-making. In cases of mixed building use, an appropriate allocation must be made. Complete documentation of the intended use is essential.
