Key legal question
Whether extraordinary maintenance costs for the transition period under Art. 218 Abs. 5 lit. a DBG are deductible for business real estate.
Extracted holding
No. The special deduction for extraordinary maintenance costs during the transition period applies only to privately held property subject to the lump-sum deduction regime, not to business real estate.
Extracted reasoning
Art. 218 Abs. 5 lit. a DBG refers to the lump-sum deduction of Art. 32 Abs. 4 DBG, which is limited to private property. Business real estate is governed by different transition rules.
