The most common entity question we hear is built on a misunderstanding: LLC and S corp are not competing options. An LLC is a legal entity created by your state; S corp is a federal tax classification an eligible LLC (or corporation) can elect. The real question is: how should my LLC be taxed?
Here is the framework, the math, and the situations where electing S corp taxation is a mistake.
Legal Wrapper vs. Tax Treatment
The LLC gives you liability protection and exists regardless of taxation. By default, a single-member LLC is taxed like a sole proprietorship (Schedule C) and a multi-member LLC as a partnership (Form 1065). Neither default changes your self-employment tax bill at all.
Filing Form 2553 layers S corporation taxation on top of the same LLC. Same company, same protection — different tax math.
The Tax Difference in One Table
For an owner-operated business netting $120,000:
- Default LLC: all $120,000 subject to 15.3% SE tax ≈ $16,955
- S corp with $60,000 salary: payroll taxes ≈ $9,180; $60,000 of distributions SE-tax-free
- Gross annual savings ≈ $7,700; net of ~$2,500 payroll/compliance costs ≈ $5,200
- At $200,000 profit, net savings typically exceed $12,000/year
When the Default LLC Wins
S corp election is the wrong move more often than the internet admits:
- Profit under ~$50K — compliance costs eat the savings
- Rental real estate — rentals pay no SE tax anyway, and S corps poison future property moves (see our entity structuring guide)
- Businesses retaining heavy profits for reinvestment where QBI and payroll interplay favors defaults
- Owners unwilling to run real payroll and keep clean books
- Certain visa holders and non-resident owners — S corps prohibit nonresident alien shareholders
California Specifics
Every California LLC pays the $800 annual franchise tax, plus a gross-receipts fee starting at $250,000 of revenue. S corps pay $800 minimum or 1.5% of net income. High-margin S corps can actually owe more state tax than an LLC paying gross-receipt fees — one more reason the decision deserves modeling with your real numbers, not a listicle.
How We Decide With Clients
We model both structures with your actual profit, a defensible salary, your state's fees, QBI impact, and retirement goals — then show the side-by-side. If the election wins, we file Form 2553, help stand up payroll, and document reasonable compensation. The full process is part of our small business tax services.

Does forming an LLC lower my taxes by itself?
No — a default LLC is tax-invisible: same Schedule C, same SE tax as a sole proprietor. LLCs deliver liability protection and credibility. Tax savings come from elections and strategy layered on top.
Can I switch to S corp taxation mid-year?
Elections are generally due 2 months and 15 days into the tax year to be effective that year, but late-election relief frequently allows retroactive treatment when you qualify. We evaluate eligibility and prepare the relief request.
What if my business income drops after electing?
You can revoke S status or simply let low-profit years ride with a proportionally lower reasonable salary. We review the election's economics annually as part of ongoing advisory.
