Short answer: for most new small businesses, an LLC with its default tax treatment is the right starting point. S-corp taxation becomes worth a serious look once your profit is steady — roughly above the $40,000–$60,000 range, as a rule of thumb — where the self-employment tax savings can start to beat the extra payroll and paperwork costs.

And one critical fact before anything else: if you are a non-US founder, the S-corp route is closed to you. Every S-corp shareholder must be a US citizen or US resident alien. Non-resident aliens cannot own S-corp shares at all — not even one share, and not through a foreign co-founder you add later. If that is you, skip to The Verdict for Non-US Founders — the LLC (with default or C-corp tax treatment) is your route.

The Short Answer

  • Choose an LLC with default taxation if you are just starting out, your profit is modest or unpredictable, you have (or might add) non-US owners, or you value simplicity over tax optimization.
  • Consider electing S-corp taxation if you are a US citizen or resident who works in the business, your profit is consistently solid, and you can pay yourself a defensible salary while still leaving money to distribute.
  • Non-US founders cannot use an S-corp at all. Start with an LLC and choose between its default pass-through treatment and a C-corp election based on your tax situation.

The Key Idea: An S-Corp Is a Tax Status, Not a Business Type

This is where most of the confusion lives. “LLC” and “S-corp” are not two versions of the same thing:

  • An LLC is a legal entity you form under state law. It is what gives you liability protection — the separation between you and the business.
  • An S-corp (an “S corporation,” named after Subchapter S of the tax code) is a federal tax classification. No state lets you “form an S-corp.” You form an LLC or a corporation first, then ask the IRS to tax it under Subchapter S.

So the real question in this comparison is not “LLC or S-corp?” It is “should my LLC keep its default tax treatment, or elect S-corp taxation?”

That also means liability protection is identical either way. The S-corp election changes how the IRS taxes you — not your legal entity, your liability shield, or your state formation. Step one either way is forming the LLC properly in the first place — name, registered agent, state filing — and the tax election is a separate decision you can make afterward.

LLC vs S-Corp: Side-by-Side Comparison

LLC (Default Taxation) S-Corp Taxation
What it is State legal entity + default federal tax rules Federal tax election (Form 2553) applied to an LLC or corporation
Formation Articles of Organization filed with your state Form the LLC or corporation first, then file Form 2553 with the IRS
Ownership rules No limit on number of owners; owners can be individuals, companies, or foreign nationals Maximum 100 shareholders; every shareholder must be a US citizen or resident alien; no corporate or partnership shareholders
Profit allocation Flexible — owners can split profits in almost any agreed ratio Rigid — distributions must be pro rata to ownership (one class of stock)
Federal income tax Pass-through: profit appears on owners’ personal returns Pass-through: profit appears on shareholders’ personal returns (via Schedule K-1)
Self-employment / payroll tax Active owners pay self-employment tax (15.3%) on their share of profit Owner-employees pay payroll tax only on salary; remaining profit distributed is free of SE/payroll tax
Payroll requirement None for owners (owners take draws) Mandatory — owners who work in the business must be on payroll with a reasonable salary
Ongoing compliance Low: personal return (plus Form 1065 for multi-member LLCs), state annual report Higher: annual Form 1120-S, K-1s, quarterly payroll filings, W-2s
Best for New businesses, non-US owners, flexible ownership, simplicity Established US owner-operators with steady, meaningful profit

How Each One Is Taxed

LLC with default taxation. A single-member LLC is a “disregarded entity” — the IRS treats the business as you, and profit lands on your personal return (Schedule C). A multi-member LLC is taxed as a partnership (Form 1065). Either way the income is pass-through, but there is a second layer people underestimate: self-employment tax. Active LLC owners pay 15.3% — 12.4% for Social Security (up to an annual wage cap the IRS adjusts most years) plus 2.9% for Medicare — on 92.35% of their net self-employment earnings. (Half of that SE tax is deductible on your personal return, which softens it slightly.) You pay regular income tax on the profit too.

S-corp taxation. The business files its own return (Form 1120-S) and issues each shareholder a Schedule K-1, so income still passes through to personal returns — no double taxation. The difference is how the owner gets paid. An owner who works in the business must take a reasonable salary through payroll, and that salary carries payroll taxes (the same 15.3% combined rate, split between employer and employee; the employer half is a deductible business expense). Profit left over after salary can be taken as distributions, which are not subject to self-employment or payroll tax. That gap — distributions escaping the 15.3% — is the entire S-corp savings story.

One caveat: salary reduces the pass-through income that may qualify for the 20% qualified business income (QBI) deduction, so at some income levels the S-corp move trades one benefit against another. A CPA should model that trade-off with your real numbers.

A Worked Example: $100,000 of Profit

Illustrative example only, with assumed figures — not a quote and not tax advice. It assumes a single US-resident owner, $100,000 of net business profit before owner pay and taxes, a $60,000 salary treated as “reasonable,” and ignores state taxes, the deduction for half of SE tax, and QBI effects to keep the comparison clean.

As an LLC (default taxation):

  • Self-employment tax base: 92.35% × $100,000 = $92,350
  • Self-employment tax: 15.3% × $92,350 ≈ $14,130
  • Plus ordinary income tax on the profit, same as below.

As an S-corp:

  • Reasonable salary: $60,000 → payroll taxes: 15.3% × $60,000 = $9,180
  • Remaining $40,000 taken as distributions → payroll/SE tax: $0
  • Plus ordinary income tax on the salary and the pass-through profit.

Gross difference: roughly $4,950 a year in this example. But that is not the amount you keep: payroll processing, quarterly payroll filings, and a separate Form 1120-S cost real money every year, and the true net saving shrinks accordingly. At lower profit levels it can shrink to nothing, which is why the break-even question matters more than the headline rate.

Notice the temptation baked into the math: the lower the “salary,” the bigger the apparent saving. The IRS knows this too, which brings us to the rule that keeps S-corp owners honest.

The Reasonable Salary Rule

If you work in your S-corp, the IRS requires you to pay yourself reasonable compensation — roughly what another business would pay someone else to do your job — before you take distributions. There is no fixed number or safe percentage in the law. The IRS looks at your duties, experience, hours, the size and profitability of the business, and what comparable businesses pay for comparable work.

Get this wrong and the consequences are not theoretical: the IRS can reclassify your distributions as wages and assess back payroll taxes and penalties. A salary of $20,000 paired with $180,000 of distributions for a full-time operator is the classic profile that invites exactly that outcome.

Practical approach: pick a salary you could defend with market data for your role, write down why it is reasonable, run it consistently through payroll, and revisit it as profits change. If the business has no profit yet, there is generally no salary to pay — the obligation kicks in when there are earnings and you are providing services. An hour with a CPA is genuinely worth paying for here.

Compliance: What an S-Corp Costs You in Time and Paperwork

Electing S-corp status is not fire-and-forget. Expect:

  • Form 1120-S every year, due March 15 for calendar-year businesses (a six-month extension is available), plus a Schedule K-1 to every shareholder.
  • Payroll, for real: quarterly Form 941 filings, annual W-2s and W-3, state payroll and unemployment filings. Most owners use a payroll service.
  • Election deadlines: Form 2553 is generally due within two months and 15 days of the start of the tax year the election takes effect (or of formation, for a brand-new business). Late-election relief exists if you have reasonable cause, but it is paperwork you would rather avoid.
  • State wrinkles: some states tax S-corps at the entity level or do not follow the federal election neatly, so check your state’s treatment before assuming the federal math is the whole story.

An LLC on default taxation has none of the payroll machinery for its owners and, if single-member, no separate federal business return at all. That simplicity has real value in year one.

When an S-Corp Wins

  • You are a US citizen or resident alien and you actively work in the business.
  • Profit is consistent and comfortably into the range where the payroll-tax saving beats payroll and prep costs — roughly $40,000–$60,000 and up, as a rule of thumb, with the case getting stronger as profit climbs.
  • You can pay a genuinely defensible salary and still have meaningful profit left over to distribute.
  • Ownership is simple and stable: few shareholders, no foreign investors on the horizon, pro-rata distributions are fine.

When an LLC (Default Taxation) Wins

  • You are a non-US founder. S-corp status is unavailable to you, full stop — see the verdict section below.
  • The business is new, part-time, or unprofitable so far. The S-corp saving is a percentage of profit; on small profit it will not cover its own compliance costs.
  • Rental real estate: rental income is generally not subject to self-employment tax anyway, so the S-corp mechanism buys little.
  • You want flexible profit splits between co-owners, or plan to bring in partners, entities, or foreign investors — all things S-corp rules restrict.

Can You Switch Later? Filing Form 2553

Yes — and this is why starting simple is low-risk. Your LLC stays an LLC under state law. To be taxed as an S-corp, an eligible LLC files Form 2553 with the IRS, and the IRS treats that filing as also electing corporate classification — a separate Form 8832 is not required for the S-corp route. (Form 8832 is the entity-classification election, the one you would use to choose C-corp taxation instead.) Every shareholder must consent, and the eligibility rules — US citizen/resident shareholders, 100 or fewer, one class of stock — are tested at that point.

Two timing notes: the election is cleanest when effective January 1, so many owners file in the last months of the prior year or the first two and a half months of the new one; and if you ever revoke or lose S status, you generally must wait five years to elect it again. If you have not formed yet, the flexible path is to form the LLC now and elect once your profit picture is clear.

The Verdict for Non-US Founders

Let us be direct, because content aimed at international founders often glosses over this: you cannot own an S-corp. S-corp shareholders must be US citizens or resident aliens. A non-resident alien shareholder does not just create a tax problem — it makes the election invalid, or terminates it the moment a foreign owner comes in. Every “LLC vs S-corp” calculator that never asks about your residency is quietly assuming a US taxpayer.

Your realistic structure choices are:

  • Single-member LLC, default treatment (disregarded entity). Simple and popular with foreign founders. Note your actual US tax bill depends on whether the LLC has US-source income effectively connected with a US trade or business — and foreign owners of disregarded LLCs have annual information reporting (Form 5472 with a pro-forma Form 1120) even in years when no tax is due. Do not skip that filing; the penalties for skipping it are severe.
  • LLC electing C-corp taxation (Form 8832). Worth a look if you plan to raise US investment or want corporate tax treatment, accepting corporate-level tax as the trade-off.
  • Revisit later. If you become a US tax resident down the road, the S-corp question reopens — with a cross-border CPA at the table, because your home country taxes you too.

(Registered agent note, since every LLC needs one regardless of tax treatment: your LLC must maintain a registered agent with a physical address in its formation state. When you form with Registered Agents Inc, the first year of registered agent service is included free — one less compliance item to arrange from abroad.)

FAQ

Is an S-corp a type of business I form with the state?
No. You form an LLC or a corporation under state law, then elect S-corp tax treatment with the IRS using Form 2553. “S-corp” describes how the business is taxed, not what it legally is.

Can a non-US citizen own an S-corp?
Only if they are a US resident alien for tax purposes. Non-resident aliens cannot be S-corp shareholders at all, and adding one terminates an existing election. Non-US founders should use an LLC with default or C-corp tax treatment instead.

How much profit do I need before S-corp taxation saves money?
There is no official threshold. As a rule of thumb, CPAs often point to roughly $40,000–$60,000 of consistent annual profit as the zone where payroll-tax savings start to outweigh payroll and Form 1120-S preparation costs. Your salary level and state rules move the break-even point, so run your own numbers.

Does an LLC taxed as an S-corp still protect my personal assets?
Yes. Liability protection comes from the LLC’s status under state law, and the S-corp election does not change your legal entity. It only changes your federal tax treatment.

Can I elect S-corp status later, after starting as an LLC?
Yes. File Form 2553 (generally within two months and 15 days of the start of the tax year you want it to cover). The IRS treats the filing as your corporate classification election as well, so Form 8832 is not needed for this route. Late-election relief may be available with reasonable cause.

Do S-corp owners still pay income tax?
Yes. S-corp income passes through to your personal return via Schedule K-1. The saving is specifically on self-employment/payroll tax: distributions above your reasonable salary avoid the 15.3%, while your salary is taxed like any wages.

The Bottom Line

Think of it as two decisions, not one. Decision one — your legal entity — is easy for almost every small business: form an LLC. Decision two — your tax treatment — can wait until the numbers justify it. Default LLC taxation wins on simplicity and is the only pass-through option open to non-US founders, since S-corp ownership is restricted to US citizens and resident aliens. S-corp taxation is a legitimate saving tool for established US owner-operators with steady profit, provided you respect the reasonable salary rule and budget for the payroll and Form 1120-S compliance that comes with it.

When you are ready to form, Registered Agents Inc’s Business Formation service costs $100 + state fee and includes your state filing, a domain name, a website, and one year of free registered agent service — so the entity is set up correctly from day one, whichever tax election you choose later. Start the LLC today, and let your first year of profit tell you whether the S-corp election is worth filing.
