What Is IRS Schedule C (Form 1040) (2012) For
IRS Schedule C (Form 1040) (2012) is used to report business income and business expenses for small business owners and sole proprietors who operate a trade or business for tax purposes. The schedule helps calculate net profit or loss by capturing revenue, costs, and ordinary and necessary expenses related to the business activity.
Filing your Schedule C is essential for accurate reporting and helps prevent issues related to an unfiled federal income tax return. It applies to a sole proprietorship, a single-member LLC, or any self-employment income that must be included on a personal tax return. Taxpayers use this schedule to meet federal requirements for reporting self-employment income on the correct tax form for the tax year.
When You’d Use IRS Schedule C (Form 1040) (2012)
You use IRS Schedule C (Form 1040) (2012) when your business activity produces taxable income that must be reported on a personal return.
- Self-employment income situations: You would file the Schedule C when you earn self-employment income as a sole proprietor or single-member LLC because this income must be reported directly on your personal tax return.
- Independent contractors: You would file the schedule when you receive payments reported on Forms 1099 because contract work requires you to report income earned through independent contractor services.
- Statutory employee rules: You would file the schedule when your employer designates your earnings as statutory employee income because statutory employee wages must be reported on Schedule C instead of wage income lines.
- Qualified joint ventures: You would file the schedule when spouses elect qualified joint venture treatment because each spouse must file a separate Schedule C to report their share of business income.
- Multiple businesses: You must complete a separate Schedule C for each distinct business activity, as the IRS requires separate reporting for each trade or business.
Schedule C is filed as part of your IRS Form 1040, ensuring all self-employment income is properly reported.

Common Mistakes and How to Avoid Them
Several filing errors can occur when preparing IRS Schedule C (Form 1040) (2012), and understanding them can help prevent IRS adjustments.
- Mixing personal and business expenses: You avoid this mistake by separating personal purchases from business use expenses and deducting only the portion that directly relates to business activity.
- Failing to report all income: You avoid IRS notices by reporting income from all sources to match the reported income amounts shown on information returns.
- Missing required forms: You avoid processing delays by including necessary attachments and ensuring that each filing schedule is completed correctly.
- Capitalizing long-term assets incorrectly: You avoid errors by capitalizing business property that produces value for more than one year rather than deducting the full cost immediately.
- Incorrect vehicle records: You avoid car and truck-related issues by maintaining mileage logs that verify the business use of your vehicle.
- Incorrect deduction claims: You avoid IRS adjustments by confirming that fees paid, wages paid, lease payments, and business insurance qualify as allowable tax deductions.
You can use a business tax transcript service to review your IRS records and verify your reported business income and deductions.
What Happens After You File
Once IRS Schedule C (Form 1040) (2012) is submitted with your tax return, the IRS reviews your figures to confirm that your profit or loss aligns with the income and expenses reported for the tax year. Net profit increases taxable income and requires you to pay self-employment taxes, including Social Security and Medicare tax components, on your personal tax return. Net loss may reduce taxable income, although the IRS may apply limitations when the loss exceeds allowable thresholds. The IRS may also match business income to information returns to ensure accurate reporting.
