What IRS Schedule SE (Form 1040) Is For
Self-employed individuals use IRS Schedule SE (Form 1040) to calculate the self-employment tax, which covers both Social Security and Medicare contributions. Unlike employees, who have FICA taxes automatically withheld from their paychecks, self-employed individuals must calculate and pay these taxes independently. The form is necessary for freelancers, small business owners, independent contractors, and others with net earnings from self-employment.
It ensures that self-employed individuals contribute to Social Security and Medicare, which provide future benefits such as Social Security retirement or disability benefits. Schedule SE also enables taxpayers to claim a deduction for half of their self-employment tax, reducing their taxable income.
When You’d Use IRS Schedule SE (Form 1040)
IRS Schedule SE (Form 1040) is required for self-employed individuals earning a net income of $400 or more from self-employment during the tax year. Self-employed individuals must pay self-employment tax on their net earnings, which includes both Social Security and Medicare portions. This form is used to calculate tax liability based on self-employment net income, including earnings reported on Schedule C, Schedule F, or other tax forms.
If your income is above the threshold, you will need to report self-employment tax. Schedule SE helps determine how much you owe for the tax year. Single-member LLC owners and independent contractors must also use this form to determine their net earnings and calculate their tax obligations.
Key Rules or Details for 2018
For the 2018 tax year, self-employed individuals must file Schedule SE (Form 1040) if their net profit from self-employment is $400 or more. This form calculates the self-employment tax, which covers both the employee and employer portions of Social Security and Medicare taxes. The self-employment tax rate for 2018 is 15.3%, comprising 12.4% for Social Security and 2.9% for Medicare, applied to net earnings from self-employment.
Net earnings include income reported on Schedule C or Schedule F, and self-employed individuals generally must pay SE tax on their gross farm or other self-employment income. The income tax deduction allows for one-half of the self-employment tax to be deducted, lowering taxable income. Social Security and Medicare taxes contribute to future benefits, such as Social Security retirement and Medicare coverage.
Additional resources for taxpayers who handle federal filing requirements can be found through the IRS Form Help Center, which provides organized guidance on form-specific instructions.
Step-by-Step (High Level)
Filing IRS Schedule SE requires careful steps to ensure correct self-employment tax reporting.
Step 1: Determine whether you need the short or long Schedule SE based on your self-employment income. Use the Short Schedule for simpler income situations, such as sole proprietorships.
Step 2: Calculate your net earnings from self-employment by reviewing income reported on Schedule C or F. Subtract allowable business expenses, including those related to Social Security taxes and Medicare benefits.
Step 3: Apply the 92.35% multiplier to your net earnings. This adjustment accounts for the employer-equivalent portion of your Social Security and Medicare taxes.
Step 4: Report the self-employment tax owed on Form 1040. You may also apply the income tax deduction for half of the self-employment tax.
Common Mistakes and How to Avoid Them
Filing Schedule SE accurately requires careful attention to detail. Below are common mistakes that self-employed individuals make and how to avoid them.
Below is a list of common self-employment tax mistakes and how to avoid them:
1. Missing self-employment tax
- How to avoid it: File Schedule SE whenever your net earnings from self-employment exceed $400.
2. Incorrect net profit calculation
- How to avoid it: Deduct all applicable business expenses from your gross income to calculate an accurate net profit.
3. Overlooking income subject to SE tax
- How to avoid it: Report all self-employment income—including freelance or side work—when determining SE tax.
4. Filing the incorrect form
- How to avoid it: Use Schedule SE specifically for calculating self-employment tax; do not rely on forms such as Schedule C or Schedule F for the SE tax calculation itself.
5. Failing to apply the tax deduction
- How to avoid it: Apply the deduction for half of your self-employment tax on Form 1040 to reduce taxable income.
Correcting these common mistakes ensures accurate filings and reduces the risk of penalties.
What Happens After You File
Once you file IRS Schedule SE, your self-employment tax is calculated and transferred to your main tax return, Form 1040. The IRS uses the information to determine your total tax liability, which includes both the self-employment tax and any applicable income tax. Your net self-employment income is subject to taxes, and the Social Security Administration will receive your earnings data to determine future Social Security benefits.
After filing, if your estimated tax payments do not cover your tax liability, you may owe additional taxes when filing your tax return. Alternatively, if you overpaid, you will receive a refund. Filing Schedule SE also affects your eligibility for credits like the earned income tax credit or additional child tax credit, based on your net income.
