What's the Difference Between an LLC and an S-Corp?

Before we dive into the tax math, let's clear up a common misconception: an LLC and an S-Corp are not an apples-to-apples comparison. An LLC (Limited Liability Company) is a legal entity type — it's a business structure you form with your state. An S-Corp is a federal tax election — it's a way the IRS taxes your business. You can actually have an LLC that's taxed as an S-Corp, and this is the setup most small business owners end up choosing.

Here's the key distinction:

·         LLC (default taxation): All net profit flows to your personal tax return and is subject to both income tax and self-employment tax (15.3%). You report income and expenses on Schedule C (for single-member LLCs) or Form 1065 (for multi-member LLCs).

·         S-Corp (tax election): You pay yourself a reasonable salary (subject to payroll taxes), and the remaining profit passes through as a shareholder distribution — free of self-employment tax. The business files Form 1120-S.

Both entities provide limited liability protection for your personal assets. Both are pass-through entities for federal income tax purposes, meaning the business itself doesn't pay income tax — profits flow to your personal return. The real difference comes down to how the IRS treats your earnings for self-employment tax purposes, and that's where the potential savings live.

How Are LLCs Taxed by Default?

By default, a single-member LLC is treated as a "disregarded entity" by the IRS. That means all of your business income and expenses show up on Schedule C of your personal tax return (Form 1040). A multi-member LLC files a separate return as a partnership using Form 1065, and each member receives a Schedule K-1 showing their share of income.

The critical point: every dollar of net profit from a default LLC is subject to self-employment (SE) tax. The SE tax rate is 15.3%, broken into two pieces:

·         12.4% for Social Security (on the first $168,600 of earnings in 2026)

·         2.9% for Medicare (on all earnings, with an additional 0.9% surtax on earnings above $200,000 for single filers or $250,000 for married filing jointly)

On $100,000 of net profit, that's roughly $14,130 in self-employment tax alone — completely separate from your federal and South Carolina state income taxes. You do get to deduct half of your SE tax on your personal return, which reduces your adjusted gross income. But you still write a check for the full $14,130. This is the tax that drives most business owners to explore the S-Corp election.

How Are S-Corps Taxed?

When your LLC elects S-Corp taxation (or you form a standalone S-Corporation), the business files its own return on Form 1120-S. Profits still pass through to your personal return — the S-Corp itself doesn't pay income tax. But here's the crucial twist: only the salary you pay yourself is subject to payroll taxes (FICA).

The S-Corp splits your income into two distinct buckets:

·         Reasonable salary: This portion is subject to FICA payroll taxes (the same 15.3%, split between employer and employee portions at 7.65% each). You'll withhold Social Security, Medicare, and federal/state income taxes from your paycheck — just like any W-2 employee.

·         Shareholder distributions: The remaining profit after salary is paid as shareholder distributions. These distributions are subject to income tax but are NOT subject to self-employment or FICA payroll tax. This is where the savings happen.

The IRS requires that your salary be "reasonable" — meaning it must reflect what someone in your role, industry, and geographic area would earn as an employee. You cannot simply pay yourself a token salary of $10,000 and take $90,000 as distributions. The IRS actively flags S-Corps with unreasonably low officer compensation, and it's one of their top enforcement priorities.

S-Corp vs LLC Tax Savings: A Real-Numbers Comparison

Let's walk through a concrete example using $100,000 in net business profit to show the difference between s corp vs llc taxes. This is the kind of analysis we perform daily for clients at Elite Pro-Tax.

Scenario A: Default LLC (Schedule C)

·         Net profit: $100,000

·         SE tax base (92.35% of net profit): $92,350

·         SE tax (15.3% x $92,350): approximately $14,130

·         Deductible half of SE tax: approximately $7,065

·         Total self-employment tax owed: approximately $14,130

Scenario B: LLC Taxed as S-Corp

·         Reasonable salary: $50,000

·         Shareholder distribution: $50,000

·         FICA payroll tax on salary (15.3% x $50,000): approximately $7,650

·         FICA payroll tax on distribution: $0

·         Total payroll tax owed: approximately $7,650

Annual tax savings with S-Corp election: approximately $6,480. Over five years, that's more than $32,000 staying in your business instead of going to the IRS. And the higher your net profit climbs, the larger the savings become. A business earning $150,000 could save $9,000 or more per year.

Keep in mind that the S-Corp does come with additional costs. You'll need to run payroll (typically $50-$150 per month through a payroll provider), file a separate business tax return (Form 1120-S, which typically costs $500-$1,500 to prepare), and potentially pay higher accounting fees. For most business owners earning above $50,000-$60,000 in consistent net profit, the self-employment tax savings easily outweigh these added costs.

The Reasonable Salary Requirement Explained

The "reasonable salary" requirement is the most misunderstood aspect of S-Corp taxation — and the area where the IRS focuses its enforcement. If you're working in your business as an owner-operator, the IRS requires that you pay yourself a salary that's commensurate with what a non-owner employee in a similar role would earn.

Factors the IRS considers when evaluating reasonable compensation include:

·         Your duties, responsibilities, and time commitment

·         Training, education, and experience required for your role

·         Comparable wages for similar positions in your industry and geographic area

·         The size, complexity, and revenue of your business

·         Your history of distributions relative to salary

There's no single formula, but a good rule of thumb is that your salary should represent at least 40%-60% of the business's net income, depending on your industry. A marketing consultant earning $120,000 in net profit might set a reasonable salary at $55,000-$70,000, for example. Setting it too low invites IRS scrutiny; setting it too high negates the tax benefits of the S-Corp election.

At Elite Pro-Tax, we use industry compensation data and IRS guidelines to help our clients determine the right salary — one that's defensible if the IRS asks questions while still maximizing your tax savings.

When Does an LLC Make More Sense?

An S-Corp isn't always the right answer. A default LLC may be the better choice if:

·         Your net profit is under $50,000 per year. The added costs of running payroll ($600-$1,800/year) and filing a separate S-Corp return ($500-$1,500) may wipe out the SE tax savings entirely.

·         Your business is brand new. In the first year or two, many businesses operate at a loss or have wildly inconsistent income. An LLC with Schedule C keeps things simple while you find your footing and establish revenue patterns.

·         You're a side hustler with a full-time W-2 job. If your business income is modest and your employer-provided W-2 already covers your Social Security contributions near the cap, the incremental savings from an S-Corp may be minimal.

·         You want maximum simplicity. A single-member LLC with Schedule C is the easiest structure to maintain. No payroll processing, no corporate tax return, minimal compliance requirements, and straightforward quarterly estimated tax payments.

·         You have significant losses to deduct. S-Corp loss deductions are limited by your basis in the company (contributions plus loans you personally make to the business). LLC members have more flexibility in deducting losses in certain situations.

Starting with an LLC and electing S-Corp status later is a perfectly valid and common strategy. You're not locked in — the S-Corp election can be made at any time (subject to filing deadlines). Many of our clients at Elite Pro-Tax take this staged approach: launch as an LLC, grow the business, and convert to S-Corp taxation once profits justify the added complexity.

When Should You Elect S-Corp Status?

The S-Corp election typically makes strong financial sense when:

·         Your net profit consistently exceeds $50,000-$60,000 per year

·         You can set a reasonable salary and still have meaningful distributions remaining

·         You're comfortable with the added compliance requirements (payroll, quarterly filings, Form 1120-S)

·         You want to reduce your self-employment tax burden without changing your liability protection

·         You plan to reinvest profits into the business rather than taking all earnings as personal income

Industries where S-Corp election is especially popular include consulting, freelance professionals, real estate agents, medical and dental practitioners, IT contractors, marketing agencies, e-commerce businesses, and skilled tradespeople. If you're a South Carolina business owner earning consistent, solid profit, it's worth crunching the numbers with a professional.

South Carolina-Specific Filing Requirements

If you're forming or restructuring a business in South Carolina, here are the state-level details you need to know for both LLCs and S-Corps:

·         LLC formation: File Articles of Organization with the SC Secretary of State. The filing fee is $110. Online filings are typically processed within 1-2 business days.

·         S-Corp election: File IRS Form 2553 at the federal level. South Carolina automatically recognizes your federal S-Corp election — no separate state election form is required.

·         State income tax: SC has a graduated income tax with rates from 0% up to 6.3% for tax year 2026. Both S-Corp salary and distributions are subject to SC income tax on your personal return.

·         SC S-Corp return: S-Corps doing business in SC must file Form SC 1120-S with the SC Department of Revenue annually.

·         Annual report: Both LLCs and S-Corps must file an annual report with the SC Secretary of State. There's no filing fee for LLCs; corporations pay a small fee.

·         Business license: Most SC municipalities — including Greenville, Easley, Simpsonville, Spartanburg, and Anderson — require a local business license regardless of your entity type.

South Carolina is generally considered a business-friendly state with relatively low costs and straightforward formation processes. That said, navigating the interplay between federal and state requirements — especially when adding an S-Corp election — is where having a local tax professional makes a real difference.

How to Make the S-Corp Election (Form 2553)

Ready to elect S-Corp status for your LLC? Here's the step-by-step process:

Step 1: Form your LLC with the South Carolina Secretary of State if you haven't already. Pay the $110 filing fee and receive your approved Articles of Organization.

Step 2: Obtain your EIN (Employer Identification Number) from the IRS. This is free and can be done online at IRS.gov in about 5 minutes. You'll receive your number immediately.

Step 3: File IRS Form 2553 (Election by a Small Business Corporation). This must be filed by March 15 of the tax year you want the election to take effect, or within 75 days of forming your entity. All shareholders must consent and sign the form.

Step 4: Set up payroll to pay yourself a reasonable salary. You'll need to withhold federal and SC state income taxes, Social Security, and Medicare from each paycheck. Most S-Corp owners pay themselves monthly or semi-monthly.

Step 5: File Form 1120-S annually to report the S-Corp's income, deductions, credits, and shareholder distributions. The deadline is March 15 (or the 15th day of the third month after the fiscal year ends).

The Form 2553 deadline is strict. If you miss the March 15 cutoff for the current tax year, you may be able to apply for late election relief under Revenue Procedure 2013-30 — but approval isn't guaranteed. Planning ahead with a tax professional ensures you don't lose a full year of savings waiting for the next election window.

Frequently Asked Questions

Can I change my LLC to an S-Corp?

Yes, and you don't need to dissolve your LLC or form a new entity. Simply file IRS Form 2553 to elect S-Corp taxation. Your LLC remains your legal entity — the S-Corp election only changes how the IRS taxes your business income.

How much can I save with an S-Corp election?

Savings depend on your net profit and reasonable salary. On $100,000 in profit with a $50,000 salary, you'd save approximately $6,480 per year in self-employment taxes. Higher earners save even more — a business netting $200,000 could save $12,000 or more annually.

What is a 'reasonable salary' for an S-Corp?

A reasonable salary is what someone in your position, with your experience and qualifications, would earn in your industry and geographic area. The IRS evaluates factors like job duties, training, experience, time commitment, and comparable wages. Our team helps clients determine the right number using industry compensation data.

Does South Carolina require a separate S-Corp election?

No. South Carolina automatically follows your federal S-Corp election. Once the IRS approves your Form 2553, SC recognizes your S-Corp status — no additional state filing is needed for the election itself.

When is the deadline to elect S-Corp status?

You must file Form 2553 by March 15 of the tax year you want the election to take effect. New businesses have 75 days from formation. Late election relief may be available under certain conditions, but it's not guaranteed.

Do I need to run payroll as an S-Corp?

Yes. If you're an owner working in the business, you must pay yourself a reasonable salary through payroll. This includes withholding federal and state income taxes, Social Security, and Medicare. Failure to run payroll can jeopardize your S-Corp status and trigger IRS penalties.
