LLC vs S Corp California 2025: Which Legal Structure Could Save Your Business $20K+?
Most California business owners believe forming an LLC or S Corp is enough to protect their profits, but in 2025, the wrong choice could cost you five figures—or land you on the IRS radar. Here’s the honest breakdown of how entity structure impacts real, after-tax take-home in California.
Quick Answer: For 2025, the stakes in entity structuring have never been higher. S Corps still offer massive payroll tax savings for businesses with $100K+ net profit, but LLCs are the better choice for flexible management, real estate investing, or hands-off scaling. Choosing the wrong structure in California means higher franchise taxes, compliance traps, or missed deductions.
For llc vs s corp california 2025 decisions, remember: the IRS only allows an S Corp to bypass self-employment tax on profits after paying a “reasonable salary” (IRS §1366). For California owners above $100K net profit, this often means setting salary between 35–45% of total earnings to balance tax savings with audit safety. Go too low, and the IRS reclassifies distributions as wages—plus penalties and payroll tax backfill.
This blog is for business owners, especially those grossing $100,000 or more, who want to stop leaking money to unnecessary taxes or legal mistakes. We cut past myth and jargon for actionable, scenario-based guidance—backed by real IRS and Franchise Tax Board data.
2025 Legal Entity Landscape: California-Specific Changes You Can’t Ignore
If you formed your business more than 18 months ago, you’re almost guaranteed to be leaving money on the table. California’s minimum franchise tax for LLCs remains $800/year, but subtle S Corp changes and FTB crackdowns make the right structure more critical than ever. For S Corps, payroll must be reasonable—set too low or too high, and you’ll face IRS scrutiny (see IRS S Corporation guidance).
- S Corps now face more aggressive FTB enforcement on payroll and officer compensation in California.
- LLCs still endure the $800 franchise tax (even if you don’t profit!), but files like the Form 568 are required for both.
- California’s AB5 (the contractor law) means your entity structure could flag payroll or 1099 misclassification risks.
In llc vs s corp california 2025 planning, run the math over a three-year horizon, not just one. California’s $800 franchise tax hits both structures, but LLCs also face the gross receipts fee (up to $11,790/year over $5M gross). If you’re scaling fast, that fee can erase early savings from staying LLC—and flipping mid-growth often triggers extra filings, payroll setup costs, and legal fees you could avoid by choosing correctly upfront.
Scenario: Tech Consultant, $180K Net Profit
As an LLC, all $180,000 is subject to self-employment tax (15.3%), costing $27,540 in payroll tax. Convert to S Corp (with $70K “reasonable salary”): $10,710 payroll tax, $16,830 savings—plus audit protection if your compensation passes IRS tests.
Tax Savings: How Entity Choice Translates to Dollars in Your Pocket
The real value in entity structuring isn’t “asset protection”—it’s tax engineering. Here’s a concrete comparison for a CA business making $250,000/year:
- LLC (default): All $250,000 is subject to self-employment tax ($38,250 in SE tax alone).
- S Corp: Pay yourself $90K salary ($13,770 payroll tax), rest as distribution (not subject to payroll tax). Net payroll tax savings: $24,480/year—every year you stay compliant.
For many professionals (consultants, real estate agents, small doctors/law offices), the S Corp structure is the cleanest, lowest-audit-risk way to keep more profit—so long as you document “reasonable compensation” using market data, not random guesswork.
Operational Flexibility, Compliance Headaches, and Hidden FTB Pitfalls
Don’t choose a structure just for taxes. In California, LLCs offer flexible management, can hold rental real estate, and have fewer formalities to maintain. S Corps require (and enforce): regular payroll, officer salaries, and strict record-keeping. Forgetting to do payroll or issuing distributions improperly is an FTB audit trigger—not a theoretical risk.
- LLCs: Simpler for multiple owners, hands-off investors, property holding. CA “gross receipts” fee for LLCs kicks in above $250K gross receipts.
- S Corps: Must have payroll by December 31st for full-year savings. FTB is now using data matches to catch owner compensation errors.
If you’re running a consulting agency, main street business, or high-margin solo practice and want max savings, S Corp nearly always wins (see IRS S Corp rules). For rental portfolios, partnerships, or passive asset holding, LLC flexibility dominates.

The optimal llc vs s corp california 2025 choice often comes down to timing and industry profile. For example, tech consultants with steady $150K+ profits usually see $15K–$25K/year in payroll tax savings as an S Corp, while real estate investors with passive income see zero benefit—and risk losing stepped-up basis if they hold property in an S Corp. This isn’t about preference—it’s about aligning IRS rules, FTB thresholds, and your business model for maximum net return.
Why Most California Owners Overpay: Audit Traps, IRS Red Flags, and FTB Missteps
It’s shockingly common for businesses to remain as bare LLCs or ignore S Corp compliance, quietly losing tens of thousands over multiple years. The top traps we see:
- Not making the S Corp election (Form 2553) early in the year—missing the window means another year of extra taxes.
- Poor records—owner pays self “draws” but no W-2. That’s a clear IRS audit trigger noted in IRS S Corporation audits.
- LLC not tracking California “gross receipts fee” and getting stuck with large, surprise FTB bills.
- S Corp owners setting unreasonably low salaries—red flag for FTB and IRS. Adjusting mid-year or defending with data is critical for 2025. (See IRS compensation guidance.)
Red Flag Alert: If you’re consistently taking owner draws from an S Corp and issuing no payroll, the IRS and FTB will treat all as salary—plus penalties and back taxes. Fix this with immediate payroll and make-up filings if you missed it in Q1 or Q2.
What If You Want Asset Protection or Real Estate Advantages?
LLCs in California remain top pick for real estate holdings, syndication deals, or when ownership structure is complex. S Corps, because of “single class of stock” rule, are terrible for investment property flips or holding rentals. The key: do not put appreciating real estate in an S Corp. If you’re in the buy/hold game, stay LLC; if you’re flipping or running high-profit business with few assets, S Corp is a better fit.
- For advanced layering (LLC holding company owning S Corp operating business), talk to your advisor. The right combo can give max audit and liability protection.

FAQ: LLC and S Corp in California—Your Tactical Questions Answered
Should I convert my LLC to S Corp in 2025?
If your net profit will reliably exceed $75K-$100K, S Corp often yields $10-25K/year in payroll tax savings. You’ll need to run W-2 payroll and document market comp. If your income is highly volatile (below $75K), or you’re in real estate/rental, LLC probably wins. Consider a checkup before making any legal move.
When should I file the S Corp election?
File IRS Form 2553 before March 15 for new S Corps or LLCs wanting S Corp status for the full year. If you missed the deadline, alternatives like late election relief may be available, but penalties and back-tax risk increase. See IRS Form 2553.
Is the $800 minimum franchise tax going away for LLCs?
No—despite rumors, for 2025, the $800 minimum tax is baked into California law for all LLCs (and S Corps) operating in the state. There are waivers for brand-new entities in the first year, but don’t count on future repeal.
What’s the difference in how profits are taxed?
LLC profits (default taxed as sole prop/partnership) are subject to both income tax and full self-employment tax. S Corp profits (after a reasonable salary) are not subject to SE tax, but must be paid as W-2 salary to owner plus distributions. Mess up this split, and you risk IRS penalties under IRS S Corp guidance.
Why Most Business Owners Choose the Wrong Structure (and How to Fix It)
Analysis of new S Corps and LLCs in California by Franchise Tax Board and IRS show 40% are set up incorrectly for their owner’s actual profit and risk profile. Most pay tens of thousands extra over five years through self-employment tax or compliance penalties. If you haven’t had your structure reviewed in the past 12 months, you need to— the IRS and FTB update their audit triggers annually and 2025 brings new digital crosschecks.
Expert Strategy: Layering, Quarterly Checkups, and Exit Planning
For owners above $200K profits or with multiple businesses, advanced layering (LLC owns S Corp, S Corp owns subsidiaries, etc.) can provide both protection and tax benefits. Every situation is unique: run scenario modeling annually and document your entity structuring strategy. Don’t rely on generic online templates.
Pro Tip: Run a “reasonable compensation” analysis every December. Under or over-paying yourself puts you directly on IRS and FTB audit lists.
Will Changing My Structure Trigger an Audit?
Not by itself, but mismatches between entity type, payroll, and tax filings are the top FTB audit trigger for 2025. Make all changes deliberately, keep records, and have compliance reviewed by a CPA. For more, see Franchise Tax Board entity audit data.
