Use Schedule C (Form 1040) to report profit or loss from a business you operated as a sole proprietor. This form is used to calculate your net profit or loss by subtracting total expenses (line 30) from gross income (line 29), resulting in the net profit or loss shown on line 31. The activity must be conducted with continuity and regularity for profit to qualify as a business; sporadic or hobby activities do not qualify.
Reporting Net Profit or Loss
- Line 31: Enter your net profit or loss. For individuals, this amount is reported on Schedule 1 (Form 1040), line 3, and on Schedule SE (Form 1040), line 2, unless you are a statutory employee (in which case, do not report on Schedule SE).
- Statutory Employees: Report net profit or loss on line 31 and include it on Schedule 1, line 3, but do not report on Schedule SE unless you have other self-employment income.
Loss Limitations
- Excess Business Loss Limitation: If you report a loss on line 31, you may be subject to the excess business loss limitation. Use Form 461 to determine the disallowed loss, which will be treated as a net operating loss carried forward. The disallowed amount is reported as income on Schedule 1, line 8p.
- At-Risk Rules: If you have investments in the business for which you are not at risk (e.g., nonrecourse loans, guaranteed amounts), complete Form 6198. Any disallowed loss under these rules is treated as a deduction in the following year.
- Passive Activity Loss Rules: If you checked “No” on line G (indicating you did not materially participate), or if your activity is rental real estate, use Form 8582 to apply passive activity loss limitations. Refer to Pub. 925 for details.
