The Form Schedule C Profit or Loss From Business
Schedule C has five parts. In Part I, you list all the income of your business and calculate your gross profit. In Part II, you subtract all your business expenses and calculate your net profit or net loss. This is the figure you report on your income tax return. You only need to complete Parts III through V if your business requires you to purchase inventory, you need to claim deductions for car expenses or if you have any other expense not listed in Part II.
