S-Corp vs LLC
An LLC is a legal entity; an S-corp is a tax election layered on top of an LLC or corporation. LLCs suit simplicity; S-corp status suits profitable owners who want to cut self-employment tax.
S-Corp vs LLC: Side-by-Side
| Dimension | LLC (default tax status) | S-Corp Election |
|---|---|---|
| What it is | A state-law business structure | A tax election an LLC or corporation can make with the IRS |
| Default taxation | Pass-through, taxed as sole proprietor or partnership | Pass-through, but profit splits into wages and distributions |
| Self-employment tax | Owner pays it on all net profit | Owner pays payroll tax only on wages, not distributions |
| Payroll requirement | None required | Owner must run payroll and take a reasonable salary |
| Paperwork and compliance | Minimal — Schedule C or partnership return | Adds Form 1120-S, payroll filings, and often a state return |
| Ownership flexibility | No restrictions on owners or classes | Limited to 100 shareholders, one stock class, U.S. individuals |
When does an LLC make more sense?
An LLC (taxed in its default status) works well when profit is modest or the business is still finding its footing. The part people miss: running payroll and filing a separate S-corp return costs time and money, and that overhead only pays off once profit is high enough to make the self-employment tax savings worth it.
If you're a new business, a side venture, or a real estate holding entity, the LLC's simplicity usually wins. It also keeps things flexible if you bring on partners or investors later, since LLCs don't face the same ownership restrictions an S-corp does. A fractional CFO can help you model the actual break-even point before you decide.
When does the S-corp election make more sense?
The S-corp election tends to make sense once net profit is consistently high enough that the self-employment tax savings outweigh the added payroll and filing costs. In plain terms: you pay yourself a reasonable salary through payroll, and the remaining profit passes through as a distribution that isn't subject to self-employment tax.
This only works cleanly with good books, since the IRS expects a defensible "reasonable salary" and accurate payroll records. If your bookkeeping isn't current, monthly bookkeeping services are usually the first step before making the election. From there, S-corp and business tax services can help with the election paperwork, payroll setup, and the annual 1120-S filing.
Frequently asked questions
Can an LLC become an S-corp without changing its legal structure?
Yes. The LLC stays an LLC at the state level; you simply file Form 2553 with the IRS to elect S-corp tax treatment. Your legal entity doesn't change, only how it's taxed.
Does an S-corp election guarantee lower taxes?
No. Savings depend on your profit level, reasonable salary requirement, and added payroll costs, so results vary by business. A comparison run through tax planning services is the reliable way to see whether it makes sense for your numbers.
What happens if I pay myself too little as an S-corp owner?
The IRS can reclassify distributions as wages and assess back payroll taxes and penalties if your salary isn't reasonable for the work you do. This is general information, not tax advice for your specific situation — book a free consultation to talk through your numbers with a professional.
