Key legal question
Whether a late extraordinary depreciation on the real estate could be accepted as a balance sheet correction for tax purposes.
Extracted holding
No. The taxpayer failed to show that the book value was unlawfully overstated, and the late write-down was motivated by the unfavorable tax assessment.
Extracted reasoning
A balance sheet correction is allowed only for unlawful accounting values, not for tax-driven late changes. The alleged overvaluation was not credibly proven; the valuation method used by the taxpayer was flawed because it relied on net rather than gross rental income. The burden of proof for tax-reducing facts lay with the taxpayer.
