My husband just started a sole proprietorship business out of or home in Aug of 2016. He purchased a new pick up truck that is eligible for Section 179. Although we have another vehicle for personal use, he does use his truck for personal use sometimes. The truck was purchased in Oct 2016 at which time he took several long mileage trips to pick up materials. Based on actual mileage in 2016 the business use percent of his truck is 91%. However, in future years we expect the business use percentage to be more like 75%. If we take Section 179 based on 91% for 2016, what will happen if our actual business use drops to 75% in future years?
