All of the assets were placed into service immediately. Mary elects to take additional bonus depreciation of $100,000 on the greenhouse, and expense the agricultural equipment under § 179. She elects maximum regular cost recovery on these assets. The business earns $600,000 in 2020 before §179 cost recovery. What is Mary’s cost recovery for 2021, and is there any carryforward?
