Tax Strategy — Entity & Tax Election
In This Guide
An LLC is a legal entity. An S-corp is a tax election — not an entity at all. An LLC can be taxed as an S-corp. So “S-corp vs. LLC” is the wrong frame: you are really choosing between an LLC taxed under its default rules and an LLC (or corporation) that has filed an S-election.
The short version: by default, all of an LLC’s active profit is hit with self-employment tax at 15.3%. An S-election splits that profit into a W-2 salary (subject to FICA) and distributions (not subject to FICA), which is where the savings come from. The election starts to pay once net profit consistently clears roughly $40,000–$50,000. In California, the math shifts because the state adds a 1.5% S-corp franchise tax on top of the federal savings.
Almost every “S-corp vs. LLC” comparison gets the premise wrong. An LLC is a legal entity created under state law. An S-corp is a federal tax classification under Subchapter S of the Internal Revenue Code. They are not two options on the same menu.
Here’s the actual issue. When you form an LLC with your Secretary of State, you have made a legal decision — you now have liability protection, an operating agreement, and a separate legal person that can own assets and sign contracts. You have not yet made a tax decision. The IRS does not have an “LLC” box on its forms. It taxes your LLC as something else.
An LLC can be taxed four different ways: as a disregarded entity, as a partnership, as an S-corporation, or as a C-corporation. The first two are the defaults. The last two require an election. So when someone asks whether they should “be an LLC or an S-corp,” the honest answer is that they can be both — an LLC that has elected to be taxed as an S-corp. The real choice is between the default tax treatment and the S-election.
The whole question here hinges on self-employment tax. That is the dollar difference between the two paths, and it is what the rest of this page is about. Keep the distinction in mind as you read: when we say “LLC” below, we mean an LLC under its default tax rules. When we say “S-corp,” we mean any eligible entity — an LLC or a corporation — that has filed Form 2553.
A default LLC passes all of its active profit through to the owners, where it is subject to both income tax and self-employment tax. An S-corp passes profit through the same way for income tax, but only the owner’s salary is subject to employment tax.
Start with the default. A single-member LLC is a disregarded entity — the IRS ignores it and treats the business as a sole proprietorship for tax purposes. You report the income on Schedule C of your personal return. A multi-member LLC defaults to partnership taxation and files Form 1065, with each owner receiving a K-1. In both cases, all net earnings from an active trade or business flow to the owners and hit self-employment tax: 15.3% on the first $176,100 of net earnings in 2026 (12.4% Social Security plus 2.9% Medicare), then 2.9% Medicare-only on everything above that wage base.
That 15.3% is the part that surprises people. It replaces the FICA taxes a W-2 employee splits with an employer. As an LLC owner, there is no employer to split with. You pay both halves. On $150,000 of net profit, that is roughly $19,500 in self-employment tax — before any income tax. You do get to deduct half of it under IRC § 164(f), which softens the blow, but it is still a real second layer of tax.
Now the S-corp. An eligible entity files Form 2553 and is taxed under Subchapter S. The business files its own return — Form 1120-S — and issues a K-1 to each shareholder. The profit still passes through to your personal return for income tax. The difference is on the employment-tax side: as an S-corp owner who works in the business, you become a W-2 employee of your own company. You pay yourself a salary, which is subject to FICA. The profit left over after your salary comes to you as a distribution, and distributions are not subject to self-employment or FICA tax. That gap is the entire tax play.
| LLC (Default) | S-Corp (Election) | |
|---|---|---|
| What it is | A legal entity, taxed under default rules | A tax election filed by an eligible entity |
| Tax return | Schedule C (single-member) or Form 1065 (multi-member) | Form 1120-S, plus a K-1 to each owner |
| How the owner is paid | Owner’s draw — no payroll, no W-2 | Reasonable W-2 salary + distributions above it |
| Self-employment / FICA exposure | All net profit subject to 15.3% SE tax | Salary subject to FICA; distributions exempt |
| Profit/loss flexibility | Flexible special allocations among members | Strictly pro-rata; one class of stock only |
| Administrative cost | Low — no payroll required | Higher — payroll, separate return, more rules |
The S-corp savings come from one move: paying yourself a reasonable W-2 salary and taking the rest of the profit as a distribution that skips the 15.3% employment tax. The salary is taxed like wages; the distribution is taxed as ordinary income but with no FICA on top.
Walk through the mechanics. Say your business throws off $200,000 in net profit. As a default LLC, all $200,000 runs through Schedule C or a K-1 and is exposed to self-employment tax. As an S-corp, you might pay yourself an $80,000 salary and take the remaining $120,000 as a distribution. Only the $80,000 carries FICA. The $120,000 is still ordinary income on your 1040 — you do not escape income tax — but it avoids the employment-tax layer entirely.
Worked Example — $200,000 Net Profit
Default LLC: the full $200,000 is subject to SE tax. First $176,100 at 15.3% = $26,943. Remaining $23,900 at 2.9% = $693. Total employment tax: about $27,600.
S-corp election: $80,000 reasonable salary → FICA of $12,240 (employer + employee combined). $120,000 distribution → no FICA. Total employment tax: $12,240.
Approximate federal savings: about $15,000 per year on the same $200,000 — before the cost of running payroll (typically $1,200–$2,400/year) and the second tax return.
That roughly $15,000 is real, repeatable money — and the reason the S-election is one of the most common pieces of advice a profitable owner-operator hears. But it comes with a catch that controls the whole strategy: the salary has to be defensible. You cannot pay yourself $10,000 and call the other $190,000 a distribution. We cover why in the next two sections.
One more interaction worth flagging. The 20% qualified business income deduction under IRC § 199A applies to pass-through profit from both a default LLC and an S-corp. For an S-corp, the QBI base is the profit net of your W-2 salary, so the salary/distribution split can move the § 199A number up or down depending on your income level and the wage limitations. A lower salary raises QBI but lowers your reasonable-comp cushion; a higher salary does the reverse. This is a calculation to run with your actual numbers, not a rule of thumb.
The S-election starts to make sense once your net profit consistently exceeds roughly $40,000–$50,000 a year. Below that, payroll costs, the extra 1120-S return, and state fees tend to eat up the FICA savings.
The breakeven logic is straightforward. The savings come only from the profit above your reasonable salary. If you net $50,000 and a reasonable salary for your role is $40,000, only $10,000 is left to take as a distribution. The FICA savings on $10,000 is about $1,530 — and payroll service, a separate return, and any incremental CPA time usually run $1,500 to $2,500. At that level you break even at best, and you have taken on real administrative work for the privilege.
The picture changes as profit climbs:
Two honest caveats. First, “consistently” matters — a one-time spike to $120,000 in a business that normally nets $45,000 is not a reason to elect, because the overhead is annual and the formalities are sticky. Second, these thresholds assume an active owner-operator. If you are a passive investor in an LLC, you may not owe self-employment tax on your share in the first place, and the analysis is different.
An S-corp buys you FICA savings, but it costs you in administration, flexibility, and audit exposure. The reasonable-compensation requirement is the big one — a salary that is too low is the number-one S-corp audit trigger.
Start with the compensation rule, because it is where most of the risk lives. An S-corp owner who works in the business must pay themselves reasonable compensation for the services they perform. The obligation traces to IRC § 3111, which imposes employment taxes on wages, and to Rev. Rul. 74-44, which holds that the IRS can recharacterize distributions to a working shareholder as disguised wages. The factors come from that ruling and the case law that followed: the nature and extent of your services, time devoted, the company’s revenue and profits, what comparable businesses pay for similar work, and whether the distribution looks proportionate to ownership rather than labor.
The case everyone cites is Watson v. Commissioner, 668 F.3d 1008 (8th Cir. 2012). David Watson, a CPA, ran his practice through an S-corp, paid himself a $24,000 salary, and distributed more than $200,000 to himself. The IRS argued the bulk of those distributions were really wages. The Eighth Circuit agreed. The logic was simple: Watson performed the work that generated the revenue, that work had a market value far above $24,000, and the structure was a transparent attempt to dodge employment tax. Watson is why a zero-salary or nominal-salary S-corp is an automatic audit flag — the IRS runs a compliance program specifically targeting S-corps with significant profit and little or no officer pay. If you elect S-corp status, set the salary with data and document it. We go deeper on how in our guide to how to pay yourself as a business owner.
Beyond compensation, the S-corp comes with structural constraints a partnership-taxed LLC does not have:
None of this is a reason to avoid the election. It is a reason to confirm the savings clear the cost and that your ownership structure actually qualifies before you file.
California changes the answer. The state taxes S-corps at a 1.5% franchise tax on net income (minimum $800), and it taxes LLCs with an $800 minimum franchise tax plus a gross-receipts fee. So the generic national advice understates the cost of an S-corp for a California business.
This is the part most online comparisons skip, and it matters a lot for our clients. California does not simply follow the federal pass-through treatment. It imposes entity-level taxes on both structures, and they are different:
California Worked Example — $200,000 Net Profit
Federal FICA savings from electing S-corp: about $15,000 (from the example above).
Less the California 1.5% franchise tax on $200,000 net income: about $3,000 that an S-corp owes and a default LLC does not.
Net benefit in California: roughly $12,000 a year, not $15,000 — still well worth it at this profit level, but meaningfully smaller than the national number suggests. At lower profit, the $3,000 state tax can erase the federal savings entirely, which pushes the California breakeven higher than the national one.
The practical takeaway: run the breakeven with the California numbers, not the federal ones. The 1.5% franchise tax raises the profit level at which the election pays, and the gross-receipts fee means a high-revenue, low-margin LLC can owe a meaningful fee regardless of which path it takes. For more on California’s entity-level taxes, see our overview of the California Franchise Tax Board.
A C-corporation pays a flat 21% federal tax at the entity level, then the owners pay again on dividends — the “double tax.” It rarely beats a pass-through for an owner who pulls profits out every year, but it can win for retained earnings, QSBS, and venture-backed companies.
A C-corp is a genuinely different animal, not a variation on the pass-through. Profit is taxed once inside the corporation at 21%, and again at the shareholder level when distributed as a dividend (15% or 20%, plus the 3.8% net investment income tax where it applies). For most owner-operators who need the cash, that second layer makes the C-corp less efficient than an S-corp or a default LLC.
There are real cases where it still wins. If you can leave earnings inside the company and have a use for them there — reinvestment, capital expenditures, building toward an acquisition — the 21% rate may beat your personal rate, and the dividend tax is deferred until you actually pull the money out. The bigger driver for many founders is Qualified Small Business Stock under IRC § 1202, which can exclude a large portion of the gain on a future sale of C-corp stock from federal tax. Venture-backed companies are also effectively required to be C-corps, because their investor base — funds, foreign investors, entities — cannot hold S-corp stock. If a sale or outside capital is on the horizon, the C-corp analysis deserves a serious look; start with our overview of QSBS and Section 1202.
The decision comes down to three questions: how much active profit you make, who owns the business, and whether you need the cash now or can leave it in the company.
Here is the framework we use with clients:
One thing to keep straight: the election is not permanent and it is not all-or-nothing across your life as a business. Plenty of owners start as a default LLC, elect S-corp status the year their profit crosses the threshold, and revisit a C-corp conversion only if a sale or capital raise comes into view. If you missed the deadline for the year you wanted, Rev. Proc. 2013-30 provides late-election relief that the IRS routinely grants, so a missed filing date is usually fixable.
Entity choice is a legal and strategic decision, not just a tax-prep checkbox. We handle the structuring, the timing of the S-election, the reasonable-compensation documentation, and the California-specific optimization — alongside your CPA, not in place of them.
The work usually breaks into four pieces: the entity analysis itself, running your actual numbers to confirm whether the S-election clears the breakeven in your state and whether your ownership even qualifies; the election mechanics, including late-election relief under Rev. Proc. 2013-30 if the deadline has passed; building a defensible reasonable-compensation position with market data and a contemporaneous written record, so a low salary is not an audit liability; and the California layer, modeling the 1.5% franchise tax and the gross-receipts fee into the decision.
We work alongside your existing CPA — or we can refer you to one if you need a good one. The legal and strategic layer is ours: entity structure, opinion-level analysis on reasonable compensation, and the documentation that holds up if the IRS or the FTB asks. The return preparation and bookkeeping stay with your accountant.

Frequently Asked Questions
Neither is “better” — they answer different questions. An LLC is a legal entity; an S-corp is a tax election an LLC can make. The real comparison is between an LLC under its default tax rules (all profit hit with 15.3% self-employment tax) and an LLC that has elected S-corp treatment (only the owner’s salary hit with FICA). The S-election is better for an active owner-operator once net profit consistently clears about $40,000–$50,000. Below that, the payroll and filing overhead usually outweighs the savings.
An LLC is a business entity formed under state law. An S-corp is a federal tax classification under Subchapter S, made by filing Form 2553. An LLC can choose to be taxed as an S-corp, so they are not mutually exclusive. The practical difference is how profit is taxed: a default LLC pays self-employment tax on all net profit, while an S-corp pays the owner a reasonable W-2 salary (subject to FICA) and treats the remaining profit as distributions that are not subject to employment tax. The S-corp also carries more rules and more administrative cost.
The savings come from self-employment tax. A default LLC’s entire net profit is subject to SE tax at 15.3% (up to the $176,100 wage base in 2026, then 2.9% above it). An S-corp splits profit into a W-2 salary, which carries FICA, and distributions, which do not. On $200,000 of profit with an $80,000 salary, that gap is about $15,000 a year in federal employment-tax savings. The catch is that the salary must be reasonable for the work performed — an artificially low salary is the number-one S-corp audit trigger.
Generally, the S-election starts to pay once net profit consistently exceeds about $40,000–$50,000. Below that, payroll services, the separate Form 1120-S return, and state fees tend to cancel out the FICA savings. Around $100,000 the savings clearly justify the election; above $200,000 they are substantial. In California, the state’s 1.5% S-corp franchise tax raises the breakeven, so run the math with California numbers rather than national rules of thumb. “Consistently” matters — a one-time profit spike is not a reason to elect.
Yes. California taxes S-corps with a 1.5% franchise tax on net income (minimum $800), which does not exist at the federal level. It taxes LLCs with an $800 minimum franchise tax plus a tiered gross-receipts fee based on total California revenue. On $200,000 of net income, the 1.5% S-corp tax is about $3,000, so the net benefit of electing is closer to $12,000 than the $15,000 federal figure. The election still pays at that profit level, but the California breakeven is higher than the generic national number.
Yes — this is the key point most comparisons miss. An LLC keeps its legal status under state law and separately elects to be taxed as an S-corporation by filing Form 2553 with the IRS. The LLC does not convert into a corporation; it simply changes its federal tax classification. The owner then becomes a W-2 employee of the LLC and takes distributions on top of salary. If you missed the election deadline, Rev. Proc. 2013-30 offers late-election relief the IRS routinely grants, so a missed filing date is usually fixable.
A C-corp pays a flat 21% federal tax, then owners pay again on dividends — the double tax that makes it inefficient for owners who pull profits out yearly. It makes sense when you can retain earnings inside the company, when you are targeting a future stock sale that could qualify for the QSBS exclusion under IRC § 1202, or when you are raising venture capital from investors who cannot legally hold S-corp stock. For a service-based owner-operator who needs most of the profit each year, a pass-through is almost always better.
