The Self-Employment Tax

Updated for Tax Year 2015


Are you starting your own business? Then get ready to pay the self-employment tax. TurboTax provides everything you need to prepare your tax return, make smart tax decisions, and get your biggest tax refund.

I'm starting a new business. Do I need to pay the self-employment tax?

So, you’ve started a business and freed yourself from the daily grind of that old job. But there’s no freedom from paying taxes. In fact, you’ll owe tax that you never had to pay as an employee. The self-employment tax (officially known as the SECA tax for Self-Employment Contributions Act tax) is the self-employed person's version of the FICA (Federal Insurance Contributions Act) tax paid by employers and employees for Social Security and Medicare, and it's due on your net earnings from self-employment.

What is the self-employment tax?

Many newly self-employed people – sole proprietors, independent contractors and the like – are surprised at their tax bills at the end of the year because they notice they're suddenly paying a lot more in tax as a self-employed person than as an employee. That's because they're carrying the full burden of paying for their Social Security and Medicare.

When you're an employee, you share that cost with your employer, with each of you paying a share of the FICA tax. When you're self-employed, though, you're stuck with the full full amount yourself.

The tax is divided into two parts:

  • 12.4 percent for Social Security. For 2015, this part of the tax applies to the first $118,500 of earnings. If you earn more than that (from self-employment or, if you also have a job, from the combination of your job and your business), then the 12.4 percent part of the tax that pays for Social Security stops for the year.
  • 2.9 percent for Medicare. The Medicare portion of the self-employment tax doesn’t stop. No matter how much you earn, you'll pay the 2.9 percent Medicare tax. For more information on this tax, see IRS Tax Topic 554: The Self-Employment Tax.

How do I report the self-employment tax?

Of course, a new tax means new paperwork too. When you start a small business and you do not incorporate or form a partnership, you report the results of your operations on Schedule C and file it with your Form 1040.

You calculate your self-employment tax on Schedule SE and report that amount in the "Other Taxes" section of Form 1040. In this way, the IRS differentiates the SE tax from the income tax.

Good news

When figuring self-employment tax you owe, you get to reduce self-employment income by half of the self-employment tax before applying the tax rate. Say, for example, that your net self-employment income is $50,000. That's the amount you report as taxable for income tax purposes on Form 1040.

But when figuring your self-employment tax on Schedule SE, Computation of Social Security Self-Employment Tax, the taxable amount is $46,175. Not paying the 15.3 percent tax on $3,225 difference in this example saves you $493.

More good news

You can claim 50 percent of what you pay in self-employment tax as an income tax deduction. For example, a $1,000 self-employment tax payment reduces taxable income by $500. In the 25 percent tax bracket, that saves you $125 in income taxes. This deduction is an adjustment to income claimed on Form 1040, and is available whether or not you itemize deductions.

An example

You run a catering business as a sole proprietor. In 2014 your net profit as reported on Schedule C is $35,000. Your net earnings as calculated on Form SE would be $32,323 ($35,000 x 0.9235). Your self-employment tax would be $4,945 (32,323 x 0.153) and you would report that amount on Form 1040 in the "Other Taxes" section.

Then you would report one-half of your self-employment tax, $2,473, ($4,945 X .50) on Form 1040 as an adjustment to income, which reduces your Adjusted Gross Income and the amount of income tax you owe.

Should I file estimated taxes?

If you have worked as an employee, you know that what you get in your paycheck is usually less than what you really made.

Why? Because your employer withheld money for Social Security, Medicare and income tax and sent that money to the government.

When you are self-employed, the entire burden for paying employment taxes and prepaying estimated income tax liability is left to you. The government wants you to make payments of your estimated taxes throughout the year in quarterly installments. If you don't, you may be subject to underpayment penalties.

If you're not sure whether you meet the definition of being self-employed, see IRS Tax Topic 554: The Self-Employment Tax.
