What Schedule C (Form 1040) (2018) Is For
IRS Schedule C (Form 1040) is a form issued by the Internal Revenue Service for self-employed individuals who report business income and business expenses. It applies to sole proprietorships, independent contractors, and small business owners who provide services or sell property for profit. The form determines net earnings, taxable income, and the correct amount of self-employment tax, which includes Social Security tax and Medicare taxes.
Schedule C information affects adjusted gross income, income tax, and eligibility for both the earned income tax credit and the child tax credit. Proper completion ensures that income sources and deductions are accurately documented for filing a tax return. Proper filing also confirms compliance with federal tax rules and supports transparency with the Internal Revenue Service.
Taxpayers reviewing filing rules and business reporting requirements often consult resources such as Individual Tax Forms when preparing Schedule C (Form 1040) (2018) and related documentation.
When You’d Use Schedule C (Form 1040) (2018)
Taxpayers file Schedule C (Form 1040) (2018) to report self-employment income and calculate their taxable business earnings. The form applies to sole proprietors, independent contractors, and freelancers who provide goods or services for payment. It also helps determine whether a filer qualifies for specific tax breaks or the standard deduction available to single filers and joint filers.
The Internal Revenue Service generally requires filing when annual net earnings exceed $400.

Individuals receiving Social Security benefits may also need to file if their income meets IRS thresholds.

What Happens After You File
After filing Schedule C (Form 1040) (2018), the Internal Revenue Service reviews the return through its automated systems. The IRS matches income and deductions against third-party forms, such as 1099s, to verify accuracy. This process helps identify reporting errors, missing entries, or inconsistencies between reported income and actual payments received.
If discrepancies appear, the IRS may send a notice requesting clarification or supporting documentation. The taxpayer must review all entries, including business and personal expense records, to confirm that figures were entered correctly. Accurate documentation helps resolve issues quickly and reduces the likelihood of a formal audit.
Once the IRS completes the review, it issues any refund or adjusts the tax liability based on verified information. Taxpayers preparing additional documents or updating prior filings may consult Federal Fillable Tax Forms to access consistent and accurate federal forms that support complete and compliant submissions.
