Final answer:
Rex can expense the entire $150,000 of new equipment under Section 179 because his net income of $50,000, after other expenses, sufficiently covers the deduction without reducing his business income below zero.
Step-by-step explanation:
Rex's decision to use Section 179 to expense the purchase of new equipment falls under business taxation rules. For the year in question, the maximum deduction limit under Section 179 is significantly higher than the $150,000 spent on the equipment, allowing for the entire purchase amount to be expensed, provided that the business's total income supports such a deduction.
Rex's gross income for the year is $1,200,000, and his expenses, excluding the Section 179 deduction, total $1,150,000. Thus, his net income before the Section 179 expense is $50,000. This means that Rex can expense the whole $150,000 purchase under Section 179 since it does not exceed his net income for the year after accounting for other expenses. It is important to note that Section 179 deductions cannot push a business's income below zero, which is not a concern in Rex's situation.
Therefore, Rex will get to expense the maximum amount he has purchased, which is $150,000, using Section 179, without any amount to carry forward to the next year.
