Self-Employment Tax Deductions

See how to maximize tax deductions when you’re self-employed.

Being self-employed isn’t always all it’s cracked up to be, especially when it comes to taxes. Not only do you have to use a tax estimator to make estimated tax payments, you also don’t have an employer to split the Social Security and Medicare taxes with. For tax purposes, the IRS considers you self-employed if you’re in business for yourself, are a sole proprietor or have a single-member LLC, or if you’re a member of a partnership. You’re required to pay self-employment taxes if you have $400 or more in self-employment income. Read on to learn what deductions you can use to reduce your self-employment tax.

Income Subject to Self-Employment Tax

Only your net income from self-employment is subject to self-employment tax. So, even though you might be self-employed, other income isn’t subject to self-employment taxes. For example, if you also have capital gains, interest income, or even employee income, those other types of income aren’t counted when calculating your self-employment taxes even though they’re subject to federal income taxes. But there’s also a number of income tax deductions that only reduce the federal income tax you owe and not your self-employment tax.

2 Types of Self-Employment Tax Deductions

You can take deductions from your self-employment taxes in two ways: business expenses and a portion of your self-employment checks. Here are details on the two self-employment tax deductions:

1. Deduction for Business Expenses

You can reduce your self-employment taxes by deducting business expenses. For example, if you have your own consulting practice and work out of your own home, your deductions could include:

  • Office supplies
  • Vehicle expenses
  • Home office expenses

Alternatively, if you own your own law firm, you could deduct:

  • Rent expenses for your office space
  • Advertising costs
  • Deductible meals and other entertainment for client development

If you sell widgets, deductions could include:

  • Costs of the goods you sell
  • Attorney’s fees to have contracts drawn up

If your business has employees, you open up a whole new wave of potential deductions. Of course, you can deduct any wages you pay your employees. If you also provide benefits, such as health insurance or contributions to a retirement plan, you can write off those costs as well. However, when making contributions to your own retirement plan, such as a SEP IRA, SIMPLE IRA, or solo 401k, those contributions only reduce your income tax and won’t reduce your self-employment taxes.

2. Deduction for Paying Self-Employment Taxes

When you’re an employee, you can’t deduct the payroll taxes that are withheld from your paychecks by your employer. When you’re self-employed, however, you can write off the portion of your self-employment checks that are equal to what an employer would have paid if you were an employee. Currently, that means you can deduct half of your self-employment taxes on your federal income taxes.

Reporting Self-Employment Tax Deductions

IRS Schedule C, Profit or Loss from Business, which is where you report all of your business income and deductions to calculate your net self-employment income. After reporting all of your income in Part I, you report your expenses in Part II. Each expense has its own line. For example, advertising costs are reported on Line 8 and office expenses are reported on Line 18.

Once you’ve calculated your net self-employment income, transfer that amount to Schedule SE to calculate the self-employment tax you’ll owe. Self-employment taxes are calculated based on 92.35 percent of your self-employment income.

Cap on Social Security Portion of Self-Employment Tax

It’s not technically a deduction, but every year there is a cap on the maximum amount of Social Security tax you can pay. For tax year 2017, the Social Security portion of the self-employment tax — 12.4 percent of the total 15.3 percent — only applies to the first $127,200 of self-employment income. If your self-employment tax exceeds that amount, you only pay the Medicare portion — 2.9 percent — on the excess.
