- 9 - properties’ adjusted bases (i.e., by receipts) or their fair market values immediately before the loss. Therefore, petitioner is not entitled to a deduction for a theft loss. Generally, damages resulting from animals and insects are not deductible because they occur not from a sudden event but rather gradually over time, unless it can be shown that the destruction was occasioned by a sudden invasion that occurred in a relatively short time (i.e., 1-3 months or 1 year). Cf. Rosenberg v. Commissioner, supra at 50; Fay v. Helvering, 120 F.2d 253 (2d Cir. 1941), affg. 42 B.T.A. 206 (1940); United States v. Rogers, 120 F.2d 244, 246 (9th Cir. 1941). The destruction of petitioner’s properties that was caused by animals’ entering the wall’s opening is not a type of “sudden, unexpected, or unusual cause” within the definition of a casualty. Without evidence to the contrary, the Court surmises that petitioner’s damages were not occasioned by a sudden invasion of raccoons and birds within a short period of time but rather occurred gradually over time (i.e., from 1998-2002). Additionally, the damages resulting from the inadequacy of the structure are neither unexpected nor unusual. Therefore, they are not deductible, and accordingly, respondent’s determination is sustained.Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 10, 2007
