Tax court rules out business deductions for RVs

(Aug. 26, 2014) -- Our finding above that petitioners had some personal use of the RV is fatal to their position. Any personal use, including watching TV in the RV, makes the entire day a personal day. Petitioners therefore used the RV as a dwelling unit for personal purposes for more than 14 days, and section 280A prohibits them from taking any deductions with respect to the RV.
