What IRS Schedule SE (Form 1040) Is For
IRS Schedule SE (Form 1040) is used to calculate the self-employment tax. This tax includes contributions to Social Security and Medicare taxes, which would typically be split between the employer and employee in a traditional job. As a self-employed individual, you are responsible for both portions, totaling 15.3% of your net earnings from self-employment.
Self-employment tax ensures that individuals who work for themselves still contribute to the Social Security and Medicare programs. This contribution is essential for your eligibility for benefits such as retirement, disability, and healthcare coverage. You must file Schedule SE if your net earnings from self-employment are $400 or more to comply with tax regulations.
When You’d Use IRS Schedule SE (Form 1040)
Individuals with self-employment income of $400 or more must file IRS Schedule SE (Form 1040). If you are a self-employed individual, this form helps you calculate the self-employment tax on your net earnings. The self-employment tax includes contributions to Social Security and Medicare, similar to those paid by a traditional employee.
This form is used to report self-employment income and deductible business expenses. It is important for those who earn income through freelancing, consulting, or other independent work. Most people need to file this form to ensure they meet tax obligations and possibly receive a refund depending on their tax situation.
Key Rules or Details for 2015

What Happens After You File
Once you submit your Schedule SE with Form 1040, the IRS processes your return and calculates your self-employment tax. The IRS will determine if you owe any additional taxes or if you qualify for a refund. Processing can take six to eight weeks, especially for paper-filed returns.
If you owe self-employment tax, the IRS will issue a bill. Payments are due by the filing deadline, and late payments will incur interest and penalties. You may set up a payment plan with the IRS if you owe taxes but cannot pay immediately, or consider a Mississippi state tax payment plan if your obligation is to the state.
For future filings, quarterly estimated tax payments may be required to avoid underpayment penalties. These payments help self-employed individuals remain compliant throughout the year.
