LLC vs S-Corp: Which Is Right for You?
This is not really a choice between two different entities. An S-Corp is a tax election you make on top of your LLC. The real question is: should your LLC be taxed as an S-Corp?

Key insight
An LLC and S-Corp are not mutually exclusive. You form an LLC, then optionally elect S-Corp tax treatment. You keep all the legal protections of an LLC while getting the tax benefits of an S-Corp.
The 30-Second Version
As an LLC owner, you pay self-employment tax (15.3%) on all your business profits. With an S-Corp election, you pay yourself a "reasonable salary" and only pay employment taxes on that salary. The remaining profit passes through as distributions, which are not subject to self-employment tax.
The savings come from the gap between your total profit and your salary. If you make $100K and pay yourself $50K, you save self-employment tax on the other $50K — roughly $7,650.
When Does the S-Corp Election Make Sense?
The $50-60K Threshold
The general rule of thumb: if your net business income consistently exceeds $50,000-$60,000 per year, an S-Corp election starts to make financial sense. Below that, the administrative costs eat up most of your tax savings.
Real Numbers: LLC vs S-Corp Tax Comparison
| Scenario | LLC (default) | S-Corp | Savings |
|---|---|---|---|
| $40K net income | $6,120 SE tax | $5,508 + costs | -$388 (not worth it) |
| $60K net income | $9,180 SE tax | $6,885 + costs | $295 (break-even) |
| $80K net income | $12,240 SE tax | $6,885 + costs | $3,355 |
| $100K net income | $15,300 SE tax | $7,650 + costs | $5,650 |
| $150K net income | $22,950 SE tax | $9,180 + costs | $11,770 |
"Costs" include payroll service (~$500/year), additional tax return (~$500-1,000/year), and potential accounting fees. Assumes reasonable salary of ~$45-60K depending on income level. Your actual numbers will vary.
The S-Corp Makes Sense When:
- Your net business income consistently exceeds $60K/year
- You are a service business (consulting, freelancing, agency)
- You do not need to retain significant earnings in the business
- You are willing to run payroll (even if it is just for yourself)
- You have stable, predictable income (not wildly variable month to month)
The S-Corp Does NOT Make Sense When:
- Your net income is below $50K
- Your income is highly variable (great months, terrible months)
- You want to retain earnings in the company for growth
- You have multiple owners with different ownership classes
- You are planning to raise outside investment (investors prefer C-Corp)
- You have significant losses you want to use on your personal return
Tax Implications in Detail
Self-Employment Tax (The Big One)
Self-employment tax is 15.3% (12.4% Social Security + 2.9% Medicare) on the first $168,600 of income (2024). Above that, you still pay the 2.9% Medicare tax, plus an additional 0.9% if you earn over $200K.
As a standard LLC, you pay this on all your business income. With an S-Corp election, you only pay it on your W-2 salary. That is where the savings come from.
The "Reasonable Salary" Requirement
The IRS requires S-Corp owners who perform services to pay themselves a "reasonable salary." You cannot pay yourself $10K and take $90K in distributions. The IRS will audit that.
"Reasonable" means what someone would be paid for the same work in the open market. For most business owners, this is somewhere between 40-60% of net income, depending on the industry. Use sites like Glassdoor or the Bureau of Labor Statistics to benchmark.
Watch out
Setting your salary too low is the #1 S-Corp audit trigger. The IRS specifically looks for S-Corp owners taking large distributions with small salaries. If audited and your salary is deemed unreasonable, the IRS will reclassify your distributions as wages and you will owe back taxes, penalties, and interest.
How to Elect S-Corp Status (Step by Step)
- Form your LLC first. You need an existing LLC (or corporation) before you can elect S-Corp treatment.
- Get your EIN. You need an Employer Identification Number from the IRS.
- File IRS Form 2553.This is the "Election by a Small Business Corporation" form. All members must sign it.
- Meet the deadline. File within 75 days of the start of the tax year you want the election to take effect. For a calendar year, this means by March 15. If you miss it, you can request late election relief.
- Set up payroll. Once approved, you need to run payroll for yourself. Services like Gusto or QuickBooks Payroll handle this for $40-50/month.
- File Form 1120-S. Instead of reporting business income on Schedule C, you will file a separate S-Corp tax return (Form 1120-S) and receive a Schedule K-1.
Common Mistakes
Electing S-Corp too early
If your income is under $50K, the costs of payroll, additional tax returns, and accounting fees wipe out any tax savings. Wait until your income is consistently high enough.
Setting salary too low
The IRS specifically targets this. If you make $200K and pay yourself $30K, you will be audited. Pay a reasonable salary based on market rates for your role.
Not running payroll
Some owners elect S-Corp but never set up payroll, just taking distributions. This is a tax violation. You must pay yourself a W-2 salary through actual payroll.
Missing the election deadline
Form 2553 must be filed by March 15 for the current year (calendar year filers). If you miss it, you will have to wait until next year or file for late relief.
Not keeping good records
S-Corps have more record-keeping requirements than standard LLCs. You need payroll records, meeting minutes, and separate tax filings. If this sounds like too much overhead, stick with the standard LLC.
Bottom Line
For most small business owners making under $50K, a standard single-member LLC is the right choice. Simple, cheap, and easy to manage.
Once you are consistently making $60K+ in net business income and you are comfortable with the additional administrative burden, the S-Corp election can save you thousands per year in self-employment taxes.
Either way, start with an LLC. You can always add the S-Corp election later. You cannot undo forming the wrong entity type.
