Line 1
Enter gross receipts from your trade or business. Be sure to check any Forms 1099 you received for business income that must be reported on this line.
If you received one or more Forms 1099-NEC, be sure line 1 includes amounts properly shown on your Forms 1099-NEC. If the total amounts that were reported in box 1 of Forms 1099-NEC are more than the total you are reporting on line 1, attach a statement explaining the difference.
Statutory employees.
If you received a Form W-2, and the "Statutory employee" box in box 13 of that form was checked, report your income and expenses related to that income on Schedule C. Enter your statutory employee income from box 1 of Form W-2 on line 1 of Schedule C and check the box on that line. Social security and Medicare tax should have been withheld from your earnings; as a result, you do not owe self-employment tax on these earnings. Statutory employees include full-time life insurance agents, certain agent or commission drivers and traveling salespersons, and certain homeworkers.
If you had both self-employment income and statutory employee income, you must file two Schedules C. You cannot combine these amounts on a single Schedule C.
