What Is Self-Employment Tax?

Self-employment tax is a tax that covers Social Security and Medicare. If you're self-employed, you're responsible for paying both the employee's and the employer's share of these taxes.

• Social Security Tax: This portion funds the Social Security program, which provides retirement benefits, disability benefits, and other social safety nets.
• Medicare Tax: This tax supports the Medicare program, which provides healthcare coverage for individuals aged 65 and older, as well as certain younger individuals with disabilities.

For employees, these taxes are typically withheld from their paychecks by their employer. However, when you're self-employed, you are responsible for paying the full amount, both the "employee" and "employer" portions.

Who Needs to Pay Self-Employment Tax?

You must pay self-employment tax if your net earnings from self-employment are $400 or more in a year. This includes:

• Freelancers
• Independent contractors
• Small business owners
• Gig economy workers (e.g., Uber drivers, Etsy sellers, etc.)

If you are employed but also have side self-employment income, you will still be required to pay self-employment tax on that income.

How Is Self-Employment Tax Calculated?

The rate for self-employment tax is 15.3% of your net earnings. This rate consists of:

• 12.4% for Social Security
• 2.9% for Medicare

Net Earnings Calculation:

To calculate your self-employment tax, you need to first determine your net earnings from self-employment. This involves subtracting any business expenses from your total income.

For example:

• Total income: $50,000
• Business expenses: $10,000
• Net earnings: $40,000

If your net earnings from self-employment are $40,000, the self-employment tax would be calculated as:

• 12.4% (Social Security) on the first $160,200 (for 2025, this limit may change in the future)
• 2.9% (Medicare) on the full $40,000

The self-employment tax would be:

$40,000 x 15.3% = $6,120

Additional Medicare Tax:

If your income exceeds $200,000 (or $250,000 for married couples filing jointly), you will also be subject to an additional 0.9% Medicare tax on the amount over these thresholds.

How to Pay Self-Employment Tax

Self-employment tax is paid when you file your annual tax return with the IRS, typically using Form 1040 and attaching Schedule SE to calculate the self-employment tax.

However, self-employed individuals are also required to make quarterly estimated tax payments throughout the year, as they do not have taxes automatically withheld from their income. These payments cover not only the self-employment tax but also income tax.

The four deadlines for estimated tax payments are:

• April 15
• June 15
• September 15
• January 15 of the following year

Deductions and Business Expenses

As a self-employed individual, you can deduct business expenses to reduce your taxable income and lower the amount of self-employment tax you owe. Common business expenses include:

• Office supplies
• Equipment (e.g., computers, tools)
• Travel and meals related to business
• Marketing and advertising costs
• Home office expenses (if applicable)

Self-Employment Tax Deduction:

There is a special deduction for self-employed individuals. You can deduct 50% of your self-employment tax on your Form 1040 when calculating your income tax. This reduces your taxable income and helps lower your overall tax bill.

For example:

If your self-employment tax is $6,120, you can deduct $3,060 from your taxable income, which may reduce the amount you owe in income taxes.

Tips for Managing Self-Employment Tax

• Track Your Income and Expenses: Keep detailed records of all income and business-related expenses. This will make it easier to calculate your net income and deductions come tax time.
• Set Aside Money for Taxes: Because taxes aren't withheld from your income, it’s a good idea to set aside a percentage of your earnings for taxes.
• Pay Estimated Taxes Quarterly: This helps avoid penalties for underpayment and ensures you don't face a large tax bill at the end of the year.
• Consult a Tax Professional: If you're unsure about how to handle self-employment tax, a certified tax professional can guide you in minimizing your tax liability and maximizing your deductions.
