Is an S-corp a different type of business entity than an LLC?

No — this is the single most common misunderstanding in this comparison. An LLC (limited liability company) is a legal entity created under state law. An S-corporation is not a competing entity type; it's a federal tax election under IRC Subchapter S that an eligible entity — an LLC or a corporation — can make by filing Form 2553. You don't choose 'an LLC or an S-corp' when you form your business. You form an LLC (or incorporate), and then separately choose how the IRS taxes it: the default treatment (a single-member LLC is a 'disregarded entity,' taxed exactly like a sole proprietorship on Schedule C) or the S-corp election. The LLC's state-law liability protection is identical either way — the election changes only the federal tax mechanics.

Which saves more money: the default LLC or the S-corp election?

It depends entirely on net profit, and the S-corp election is not automatically better. Below roughly $40,000-$80,000 of net profit (state-dependent), the added cost of payroll, a separate Form 1120-S return, and state franchise fees typically exceeds the self-employment tax saved. Above that range, the S-corp election usually wins on SE tax alone — but it also shrinks your Qualified Business Income (QBI) deduction, since the salary portion isn't QBI-eligible while the whole Schedule C profit is. The two effects move in opposite directions, so the real comparison requires running both the SE-tax savings and the QBI difference together, not evaluating either alone.

Does electing S-corp status change my liability protection?

No. Liability protection comes from the LLC itself — the fact that it's a separate legal entity under state law, shielding your personal assets from business debts and claims (with the usual exceptions like personally guaranteed debt or your own negligence). The S-corp election is purely a federal tax classification layered on top of that same LLC. Electing S-corp status doesn't add, remove, or change the liability shield in any way — a single-member LLC taxed as a disregarded entity and the same LLC taxed as an S-corp have identical liability protection.

Do I need payroll if I stay a default LLC, or only if I elect S-corp?

Only if you elect S-corp. A default single-member LLC, taxed as a disregarded entity, has no payroll requirement at all — you pay yourself by simply moving money from the business account to your personal account (an 'owner's draw'), and the entire net profit is subject to self-employment tax on Schedule SE. Once you elect S-corp status, the IRS requires you to pay yourself a 'reasonable compensation' W-2 salary through actual payroll, with FICA withheld and deposited each pay period — you can no longer just draw money informally for the salary portion. This is the single biggest operational change the election brings, and it's the source of most of the added cost and complexity.

Can I switch from a default LLC to an S-corp election later, or is it permanent?

You can switch, and many freelancers do exactly this — starting on the default LLC treatment while profit is modest, then filing Form 2553 once profit clears the break-even point. The election isn't permanent or irrevocable in a way that traps you; it can be revoked later too, though the IRS generally won't let you re-elect S-corp status for five years after a revocation without permission. Because the election must be filed by March 15 for a calendar-year entity to apply to that full year (or you can seek late-election relief under Rev. Proc. 2013-30), most freelancers evaluate the switch at year-end for the following year rather than mid-year.

S-Corp vs. LLC Taxes for Freelancers: What's Actually Being Compared (2026)

Published: August 30, 2026 · Reading time: 9 min

TL;DR: "S-corp vs. LLC" is a misleading question — an LLC is a state-law entity, and an S-corp is a federal tax election an LLC can make. The real comparison is between two ways of taxing the same LLC: the default disregarded-entity treatment (full net profit subject to 15.3% self-employment tax on Schedule C) versus the S-corp election (a reasonable-compensation salary subject to payroll tax, plus a distribution that's exempt from SE tax entirely). At $150,000 of net profit with an $80,000 reasonable salary, the S-corp election saves about $8,954 in SE/payroll tax, minus roughly $3,000 in added payroll and filing cost, minus about $3,331 in extra income tax from a shrunken QBI deduction — a true net benefit of about $2,623, not the full SE-tax savings often quoted. Liability protection is identical either way; only the federal tax mechanics change.

Freelancers searching "LLC vs. S-corp" are usually asking the wrong question, and most of what they find online doesn't correct it. An LLC is a legal entity formed under state law — it's what gives you personal liability protection. An S-corporation is not a competing legal entity at all; it's a federal tax election under IRC Subchapter S, made via Form 2553, that an already-existing LLC (or a corporation) can choose. You don't pick one or the other when starting your business — you form the LLC, and separately decide how the IRS taxes it.

This guide compares the two real options for a freelancer's single-member LLC: staying on the default disregarded-entity treatment or making the S-corp election — side by side, with the 2026 numbers.

What's Actually Different: A Direct Comparison

	Default LLC (disregarded entity)	LLC with S-Corp Election
Legal entity type	LLC (state law)	Same LLC (state law) — election doesn't change it
Liability protection	Full LLC shield	Identical — unaffected by the election
How you're taxed	Schedule C, like a sole proprietorship	Form 1120-S, profit passes through via Schedule K-1
Self-employment / payroll tax	15.3% on ~92.35% of full net profit, up to the SE tax wage base ($184,500 in 2026)	15.3% only on the reasonable-compensation salary; the distribution above it pays no SE/payroll tax
Payroll required?	No — pay yourself by informal draw	Yes — real payroll with FICA withholding, Form 941 filings
Annual tax return	Schedule C attached to your 1040	Separate Form 1120-S, plus Schedule K-1 and your 1040
QBI (§199A) deduction base	Net profit less half the deductible SE tax	Distribution only — the salary is excluded from QBI
Added annual cost	Effectively none beyond normal bookkeeping	Payroll service, Form 1120-S prep, possible state franchise tax — typically $1,500–$4,500/year
Best for	Lower or inconsistent profit; simplicity	Profit consistently above roughly $80,000–$100,000

The Self-Employment Tax Math

On the default LLC treatment, the entire net profit is subject to self-employment tax: 15.3% on 92.35% of net profit up to the 2026 Social Security wage base of $184,500, then 2.9% (Medicare only) above that.

On the S-corp election, only the reasonable-compensation salary is subject to payroll tax at the same 15.3% rate (again up to the wage base). The distribution — profit above the salary — passes through on Schedule K-1 and is not subject to SE tax or payroll tax at all. That gap is the entire basis of the S-corp tax strategy.

Worked Example: $150,000 Net Profit

A freelance consultant projects $150,000 of net profit for the year and estimates a defensible $80,000 reasonable-compensation salary based on comparable market rates for the work.

Default LLC (Schedule C):

	Amount
Net profit	$150,000
SE-tax base (92.35%)	$138,525
Self-employment tax (15.3%)	$21,194

LLC with S-corp election:

	Amount
Reasonable-comp salary	$80,000
Distribution	$70,000
Payroll tax on salary (15.3%)	$12,240
SE/payroll tax saved vs. default	$8,954

Subtracting an estimated $3,000 in added payroll service, Form 1120-S preparation, and state fees leaves a $5,954 raw savings — the number most articles stop at.

The QBI Deduction Cuts Into the Savings

The Qualified Business Income deduction (up to 20% of QBI) applies to both scenarios, but the S-corp's W-2 salary is not QBI — only the distribution is:

Scenario	QBI base	20% QBI deduction
Default LLC (net profit less ½ SE tax)	$139,403	$27,881
S-corp (distribution only)	$70,000	$14,000

That $13,881 smaller QBI deduction ($27,881 vs. $14,000) costs roughly $3,331 in additional income tax at a 24% marginal rate — a real cost that most "S-corp saves you thousands" comparisons leave out entirely.

True net benefit: $8,954 (SE-tax saved) − $3,000 (added cost) − $3,331 (QBI tax cost) = $2,623. Still a genuine saving at this profit level — but roughly a third of the headline $8,954 figure, and the margin narrows further for a Specified Service Trade or Business freelancer already near the 2026 QBI phase-in thresholds of $201,750 (single) / $403,500 (MFJ), where the deduction is already shrinking regardless of the election.

Why the Election Doesn't Touch Liability Protection

A common misconception is that electing S-corp status offers additional legal protection on top of the LLC. It doesn't. The liability shield comes entirely from forming the LLC itself under state law — a separate legal entity that keeps business debts and claims away from your personal assets (subject to the usual exceptions: a personally guaranteed loan, your own negligence, or piercing the corporate veil through commingled funds). The S-corp election is purely a federal tax classification laid on top of that same entity. A single-member LLC taxed as a disregarded entity and the identical LLC taxed as an S-corp have exactly the same liability protection — the election changes the tax return, not the entity.

What the S-Corp Election Actually Adds

Choosing the election isn't just a form you file once — it changes how you operate all year:

Real payroll, not an informal draw — a service like Gusto or OnPay running FICA withholding and deposits each pay period
Form 941 quarterly payroll tax filings
A separate Form 1120-S corporate return each year, plus a Schedule K-1
An accountable plan for any expense reimbursements, or they become taxable wages
State franchise tax in some states (California's $800 minimum is the most commonly cited example)

None of this is difficult, but it's real, ongoing administrative work that a default LLC on Schedule C simply doesn't have. Factor the time cost, not just the dollar cost, into the decision.

When Each Makes Sense

Stay on the default LLC treatment when:

Net profit is inconsistent or under roughly $40,000
You're in year one or two and still ramping up
You'd rather not run payroll or pay someone to run it for you

Consider the S-corp election when:

Net profit has consistently cleared $80,000–$100,000 for at least a full year
You have (or are willing to build) a defensible reasonable-compensation number
You're comfortable with monthly payroll and an annual 1120-S, or willing to pay for both

Run the full math with a CPA when:

Profit falls in the $40,000–$80,000 range, where the state you're in and your reasonable-comp ratio decide the answer
You're a Specified Service Trade or Business freelancer near the QBI phase-in range, where the QBI hit can offset most of the SE-tax saving
