During 2022, Leisel, a single taxpayer, operates a sole proprietorship in which she materially participates. Her proprietorship generates gross income of $142,000 and deductions of $420,000, resulting in a loss of $278,000. The large deductions are due to the acquisition of equipment and the use of immediate expense and additional first-year depreciation to deduct all of the acquisitions. Can Leisel use all of this loss to offset other income she has? Explain.
