@wakefern58 Ordinary income is exactly what it is – income from operations, and expenses related to a normal course of business.
It's income directly related to operations (manufacturing, sales, services) and expenses incurred to produce this income (salaries to employees, their insurance, office rent, normal depreciation expense of your assets used in business, repairs and maintenance, travel, meals and entertainment, advertising).
Interest income, royalties, dividend income are both portfolio income, this income is not derived from normal operations but rather from investments.
179 is not an “actual” expense incurred in the course of business
Charitable contributions are not in any way related to producing your ordinary income.
This is probably the most simplified explanations but I hope it makes sense.
