One of the most common questions we hear at S&S CPA INC in Downey is whether a California business should be organized as an LLC or elect S-Corporation status. The answer is not the same for every owner. It depends on profit level, how much of the work you personally perform, whether you have partners, your plans for retirement contributions, and how much administrative overhead you are willing to carry.
This guide walks through the real numbers — including California's $800 minimum franchise tax, the LLC gross-receipts fee, the self-employment tax savings of an S-Corp, and the reasonable-compensation rule that most DIY filers get wrong. By the end you will know at roughly what profit level the S-Corp election starts to save you money in California.
How a California LLC is taxed by default
A single-member LLC is a disregarded entity for federal income tax. All profit flows through to the owner and is reported on Schedule C of the personal return. A multi-member LLC files a partnership return (Form 1065) and issues K-1s to each member.
In both cases the net profit is subject to self-employment tax at 15.3% on the first $168,600 (2024 wage base, indexed) and 2.9% Medicare above that, plus an additional 0.9% Medicare surtax on high earners. This is the tax that surprises new business owners the most — it applies on top of ordinary federal and California income tax.
California layers on the $800 minimum franchise tax that every LLC owes each year regardless of profit, plus a gross-receipts LLC fee that starts at $900 once total California-source revenue exceeds $250,000 and climbs to $11,790 above $5 million.
How an S-Corporation is taxed
An S-Corporation files Form 1120-S at the federal level and Form 100S in California. Profit is not subject to self-employment tax. Instead the owner-employee must be paid a reasonable W-2 salary, which does carry payroll tax. Any profit above that salary flows through on a K-1 as distribution income and escapes the 15.3% self-employment layer.
That is the entire tax-savings mechanism of the S-Corp election. If you pay yourself a $90,000 reasonable salary and the company has $80,000 of additional profit, roughly $80,000 avoids self-employment tax — a federal savings of about $12,000 per year for a typical service business.
California, however, imposes a 1.5% franchise tax on S-Corp net income with an $800 minimum. So the California cost of the S-Corp is higher than the LLC's $800 flat fee, and the calculation must include it.
The reasonable-compensation rule (and why the IRS cares)
The IRS requires S-Corporation owner-employees to pay themselves reasonable compensation for the services they perform before taking distributions. Owners who zero out W-2 wages and take everything as distributions are a known audit target.
Reasonable compensation is what you would pay a non-owner employee to do the same work in your market. For a Downey-based dentist, marketing agency owner, or consultant this is usually documented with BLS wage data, industry compensation surveys, or a comparable-role analysis. We prepare a written reasonable-compensation memo for every S-Corp client we set up, which becomes the first document we produce if the IRS ever questions the wage.
At what profit level does the S-Corp actually win?
As a working rule for California service businesses, the S-Corp election starts to pay for itself once net profit (before owner comp) reaches roughly $80,000–$100,000. Below that, the extra payroll processing, corporate tax return, 1.5% California franchise tax, and reasonable-compensation study cost about as much as they save.
Between $100,000 and $250,000 of profit, the S-Corp typically saves $5,000–$15,000 per year in California after all added compliance costs. Above $250,000 the savings scale further but flatten because the wage base cap on Social Security is already covered by the reasonable salary.
Every situation is different — this is not one-size-fits-all — and the number is very sensitive to your reasonable-comp figure and whether you already run payroll. We model it for each client before recommending the election.
When the LLC is the better answer
Real-estate holding entities almost always stay as LLCs — rental income is not subject to self-employment tax to begin with, so the S-Corp buys nothing but costs the 1.5% California franchise tax and payroll setup.
New businesses that have not yet cleared six figures in profit usually stay as LLCs for the first year and revisit the election when they file the second return.
Businesses with foreign partners, venture capital plans, or a multi-class ownership structure cannot use the S-Corp election at all and should stay as an LLC or C-Corp.
Frequently asked questions
Can I convert my California LLC to an S-Corp without dissolving the entity?
Yes. You keep the LLC as the legal entity and file IRS Form 2553 to elect S-Corp tax treatment. The LLC keeps its EIN, bank accounts, and contracts. Only the tax reporting changes.
Do I still owe the $800 California franchise tax as an S-Corp?
Yes. Both LLCs and S-Corps owe the $800 minimum franchise tax to the FTB each year. S-Corps also owe 1.5% on net income above roughly $53,000 (the point where 1.5% exceeds $800).
What is a reasonable salary if I am the only employee?
It's what you would pay someone else to do your job in your market. We benchmark it against BLS occupational wage data and industry comp surveys, and we document the analysis in a written memo you keep in your permanent file.
When during the year should I file the S-Corp election?
Form 2553 must generally be filed within 2 months and 15 days of the start of the tax year you want the election to apply to. Late elections are often granted with reasonable cause, but do not rely on it — plan the election, do not scramble.
Conclusion
The LLC-vs-S-Corp decision is one of the highest-leverage tax choices a California business owner makes. The savings can be five figures per year — or the wrong election can add cost with no benefit. Run the numbers with a CPA before you file the paperwork.
