LLC vs. S-Corp: Cut Self-Employment Tax by $4,000

Learn how choosing the right business structure can save you thousands in self-employment taxes as your income grows.

By MyBizNerd Team · Published

Key Takeaways

  • An S-Corp election can save an owner roughly $5,000 to $9,000 in self-employment taxes once annual profits clear the $70,000 mark.
  • You must pay yourself a 'reasonable salary' under IRS rules to maintain S-Corp status, which adds payroll processing costs of $500 to $1,500 per year.
  • Business owners can often file IRS Form 2553 to change their tax status without dissolving their existing LLC entity.
  • Standard LLCs pay a 15.3% self-employment tax on all profits, while S-Corps only pay that tax on the designated salary portion.

According to data from the U.S. Census Bureau in 2022, nearly 80% of small businesses have no employees, yet many of these solo operators remain structured as standard LLCs long after it stops making financial sense. This choice often boils down to a lack of clarity on how different structures impact the as highlighted in a recent guide by Small Biz Trends regarding business definitions.

Say you run a solo consulting business or a specialized trade like HVAC repair. You pull in $110,000 in net profit after expenses. If you stay a standard single-member LLC, the IRS treats you as a disregarded entity. You'll pay the 15.3% self-employment tax on almost every dollar of that $110,000. That's roughly $16,800 just for Social Security and Medicare before you even touch your income tax brackets.

The Math That Saves You Money

If you elect S-Corp status, you split that $110,000.

You might pay yourself a 'reasonable salary' of $60,000. 3% tax on that $60,000 ($9,180). The remaining $50,000 is taken as a distribution, which isn't subject to self-employment tax. You just saved over $7,600 in one year. Even after paying $1,000 for a payroll service and extra tax prep, you're up by $6,600.

Three Actions for Your Week

  1. Run the $70k test. Review your 2023 Schedule C. If your net profit was over $70,000, ask your CPA to run a side-by-side comparison of your current tax bill versus an S-Corp election. Generally, the administrative costs of an S-Corp aren't worth it until you hit this threshold.
  2. Check your state's S-Corp fees. While the IRS election is free, states like California charge a minimum franchise tax ($800) for S-Corps. Search your Secretary of State website for 'entity filing fees' to see the local cost of switching.
  3. Draft a 'Reasonable Salary' memo. If you decide to switch, you must justify your pay to the IRS. Use the Bureau of Labor Statistics to find the median wage for your job title in your zip code. Print this out and keep it in your tax folder.

The Administrative Reality Check

The reason most people don't start as S-Corps is the 'Reasonable Salary' requirement. The IRS is very clear: you cannot pay yourself $10,000 and take $90,000 in tax-free distributions if the market rate for your work is $70,000. You can find guidance on what the IRS considers a business versus an employee relationship on the IRS official site.

  • You must run a formal payroll (paying into unemployment and withholding taxes).

  • You must file a separate corporate tax return (Form 1120-S).

  • You must keep more rigorous bookkeeping records than a simple LLC.

  • Failure to pay a salary can lead to the IRS reclassifying all your distributions as wages, hitting you with back taxes and penalties.

Can I keep my LLC and just change the tax status?

Yes. This is a common point of confusion. You don't have to incorporate as a 'Inc' to get these benefits. Most small business owners remain a legal LLC at the state level but file IRS Form 2553 to be taxed as a Subchapter S Corporation. This gives you the liability protection of the LLC with the tax flexibility of the S-Corp. (Disclosure: we may earn a commission if you sign up for legal or tax services through our links.
