Personal property held out for rental is not “stock-in-trade" under sub. (17). Village of Menomonee Falls v. Falls Rental World, 135 Wis. 2d 393, 400 N.W.2d 478 (Ct. App. 1986).
The exemption under sub. (9) applies only to personal property. Pulsfus v. Town of Leeds, 149 Wis. 2d 797, 440 N.W.2d 329 (1989).
“Interstate traffic" in sub. (3) means interstate commerce; what constitutes a boat in interstate commerce is discussed. Town of LaPointe v. Madeline Island Ferry, 179 Wis. 2d 726, 508 N.W.2d 440 (Ct. App. 1993).
A mobile home is an improvement to real property under s. 70.043 (1) when the home is resting for more than a temporary time, in whole or in part, on some other means of support than its wheels, but a mobile homes may be personal property and exempt under sub. (19) (b) although it may have some weight off its wheels. Ahrens v. Town of Fulton, 2002 WI 29, 251 Wis. 2d 135, 641 N.W.2d 423, 99-2466.
In applying sub. (20), the use of the equipment rather than the primary purpose of the underlying business is the determining factor in deciding whether equipment is exempt from taxation. De minimis uses of the property are not sufficient to invoke this exemption. Village of Lannon v. Wood-Land Contractors, Inc., 2003 WI 150, 267 Wis. 2d 158, 672 N.W.2d 275, 02-0236.
Sub. (22) unambiguously expresses the legislature's clear intent to exempt rental property from taxation that is held for rental for one month or less and for property available for rental for more than one month to be taxed. There is no ambiguity in the statutory language such that it might possibly apply to property that is held for rental for one month or less and that is also available for rental for more than one month. United Rentals, Inc. v. City of Madison, 2007 WI App 131, 305 Wis. 2d 120, 741 N.W.2d 471, 05-1440.
As used in sub. (1), “kept for personal use" does not explicitly limit the use of personal property solely to personal use. The decisive question is whether the use is de minimus or inconsequential. Faydash v. City of Sheboygan, 2011 WI App 57, 332 Wis. 2d 397, 797 N.W.2d 540, 10-2073.
