Congratulations. You finally started your own business. Years of working for somebody else are finally over. Now you set your own schedule and reap 100% of the profits from your hard work. Unfortunately, what they don’t tell you is that even though you don’t have any traditional payroll, you still have to pay payroll taxes on your self-employment income in the form of the dreaded self-employment tax. Many new business owners are unaware of this tax and feel bamboozled by their accountants when they go to file their returns for the first time and are notified of this extra tax.

What is self-employment tax and who is subject to SE taxes?

Self-employment income is the earned income derived from the business operations for people who operate as independent contractors, freelancers, sole proprietors, single -member LLCs, and some other small business owners. All SE income is subject to SE taxes. Typically, this applies to all business owners who are either disregarded entities or partners in a service partnership. Disregarded entity is a business that, one, has a single owner or two, not organized as a corporation or three, not elected to be taxed as a separate business entity. Even if you have elected to be treated as a partnership, you may still be subject to SE taxes on your flow through SE income.

What is SE tax?

SE tax is essentially payroll tax, charged at the individual level on Form 1040 to disregarded entities and partners receiving flowed through SE income. SE tax is comprised of two parts, Social Security tax and Medicare tax. As an employee, you would consistently see those extra withholdings on each check in tandem with your income tax withholdings. What you didn’t see was that your former employer was paying a matching amount on those taxes to the government. What? They were paid twice? Yes. And as the owner of your business, acting as the employer and the employee, you now get to pay both sides to a whopping total of 15.3%. The Social Security tax makes up 12.4 % and the Medicare tax makes up 2.9% for the total 15.3. However, there is some relief as the Social Security tax is capped annually after achieving a certain wage base. For 2025, that limit is $176,100. But you still have to pay the 2.9 % on the amount over that, and the Medicare tax bumps up to an additional 3.8 % for people making over $200,000 if you’re single or $250,000 if you’re filing jointly.

How and where is SE tax calculated on my return?

SE tax is calculated on your net income from operations of your business. Net income includes all of your offsets and proper business deductions, including one half of the SE tax, the employer’s side. Net income for disregarded entities is calculated on your Schedule C, profit, or loss from business. For partners in a partnership, it is flowing through your K-1, line 14, and reported on Schedule E, page 2. The tax itself is calculated on Schedule SE and includes all your SE income from all sources.

How do you pay the asset tax?

Although the tax is calculated on your return, you are required to pay as you go using the estimated tax payment system.
