An S Corp is a federal tax status that a corporation or LLC can elect with the IRS. Instead of being a separate kind of business you form, it changes how the IRS taxes a business you already have, and how you pay yourself from it.
If you’re self-employed, you’ve likely heard the term from other freelancers or your accountant. However, it’s easy to mix up an S Corp with an LLC, a corporation, or a tax strategy. This guide explains what an S Corp actually is, how it compares to other structures, who can become one, and what changes once you do.
What is an S Corp?
An S Corp (short for S corporation) is a business that has elected to pass its income, losses, deductions and credits through to its owners for federal tax purposes (IRS). In other words, the owners report the business’s profit on their personal tax returns, and the business itself generally doesn’t pay federal income tax.
What sets an S Corp apart is how owners who work in the business get paid. Instead of taking all profit as owner draws, you pay yourself a salary through payroll and can take remaining profit as distributions. That structure is the reason many self-employed people consider the election.
Here’s an S Corp at a glance:
| S Corp | |
|---|---|
| What it is | A federal tax election, not a legal entity type |
| Who grants it | The IRS, when an eligible business files Form 2553 |
| Who can elect it | An eligible LLC or corporation |
| How profit is taxed | Passes through to owners’ personal returns |
| How owners get paid | A reasonable salary through payroll, plus distributions |
| What it doesn’t change | Your legal entity, liability protection, or state registration |
Why the S Corp exists
The S Corp is an intentional part of federal tax law, built specifically for small businesses. In 1954, President Eisenhower asked Congress to make taxes less of a factor in how small, closely held businesses chose to organize. At the time, owners faced a hard choice: form a corporation and pay tax twice, once at the business level and again on dividends, or stay unincorporated. Congress responded in 1958 by adding Subchapter S to the Internal Revenue Code, which is where the “S” comes from. As a result, small businesses could keep a corporate structure while paying tax once, at the owner level.
Since then, Congress has expanded the rules several times, including raising the owner limit to 100 in 2004. Today, the IRS publishes clear guidelines for how S Corps operate, along with guardrails like the reasonable salary requirement. In other words, electing S Corp status is a choice the tax code deliberately offers small business owners, as long as they follow the rules that come with it. By contrast, a regular corporation that hasn’t made the election is a “C Corp,” named after Subchapter C.
What an S Corp is not
An S Corp isn’t a business entity you form with your state. Your state forms an LLC or corporation; the IRS then recognizes the S Corp election. As a result, your liability protection comes from your LLC or corporation, not from the S Corp status itself. Similarly, electing S Corp status doesn’t give you a new business name or, in most cases, a new EIN.
How an S Corp compares to other business structures
Because an S Corp is a tax status, it helps to see it next to the structures self-employed people most often use. Here’s how they compare for a business with one owner:
| Sole proprietorship | Single-member LLC | LLC or corporation with S Corp election | C Corp | |
|---|---|---|---|---|
| Legal entity you form with your state | No | Yes | Yes | Yes |
| Liability protection | No | Yes | Yes | Yes |
| How the IRS taxes profit | On your personal return | On your personal return | Passes through to your personal return | Taxed at the corporate level, then again when paid out as dividends |
| How you pay yourself | Owner draws | Owner draws | Salary through payroll, plus distributions | Salary, plus dividends |
| Self-employment or payroll tax | Self-employment tax on all net profit | Self-employment tax on all net profit | Payroll taxes on your salary only | Payroll taxes on your salary only |
| Separate business tax return | No | No | Yes | Yes |
For a Business-of-One, the default setup is especially different. Without an election, the IRS treats a single-member LLC the same as its owner, so all of the profit flows to your personal return and generally faces self-employment tax. The S Corp election, on the other hand, separates the salary you earn for your work from the profit you take as an owner.

How a business becomes an S Corp
Who can be an S Corp
S Corp status is open to small businesses of any size, from a single owner up to 100, as long as the business and every owner meet the IRS eligibility rules. To qualify, a business must:
- Be a domestic (U.S.) corporation or LLC.
- Have no more than 100 owners (shareholders).
- Have only allowable owners, such as individuals, certain trusts and estates. Partnerships, corporations and nonresident aliens can’t be owners.
- Have only one class of stock.
- Not be an ineligible business, such as certain financial institutions and insurance companies.
For most freelancers and solopreneurs with an LLC, these rules aren’t a hurdle. However, they matter if you plan to bring on investors or business partners later.
How the election works
First, you need a legal entity, usually an LLC. A sole proprietorship can’t elect S Corp status on its own. Then, you file Form 2553 with the IRS to make the election, and every owner signs it. Timing matters, because the effective date determines which tax year the election covers.
For the step-by-step process, see how to convert an LLC to an S Corp or how to start an S Corp. If you’re past the deadline for this year, switching to an S Corp mid-year and retroactive S Corp elections explain your options.
How states handle the S Corp election
The S Corp election happens at the federal level, but states decide how to treat it. Most states follow your federal election automatically. However, some require a separate state election or form, and a few states and cities don’t recognize S Corp status at all, taxing the business more like a regular corporation.
Beyond the election itself, states vary on which business returns they require, whether they charge franchise taxes, entity-level taxes or annual fees, and how you register for state payroll accounts. As a result, the filing logistics of an S Corp extend well beyond federal requirements. Before you elect, check your state’s rules with your state tax agency or a local tax professional.

What changes when you operate as an S Corp
Electing S Corp status changes more than your tax return. In fact, it changes how you run the business week to week. Here’s what to expect:
- You become an employee of your business. As a result, you pay yourself a reasonable salary through payroll, with taxes withheld.
- You take profit differently. Beyond your salary, you can take remaining profit as distributions. Here’s how owner’s draws and salary differ and how S Corp distributions work.
- You run payroll. That means payroll tax deposits, quarterly payroll filings and a W-2 for yourself each year. Our S Corp payroll guide covers setup.
- Your books get more detailed. Specifically, you track salary and distributions separately and keep books that support a balance sheet. See S Corp financial management.
- You file a separate business tax return. In addition to your personal return, your S Corp files its own return each year. For how the taxes work, see our S Corp taxes guide.
Benefits and trade-offs of an S Corp
An S Corp can be a strong fit for many self-employed people. Still, it’s a trade: potential tax savings in exchange for more structure and admin.
| Potential benefits | Trade-offs |
|---|---|
| Payroll taxes apply only to your salary, not all of your profit | You must run payroll and pay yourself a reasonable salary |
| Profit still passes through to your personal return, avoiding corporate-level income tax | You file a separate business tax return each year |
| A clearer line between what you earn for your work and what you earn as an owner | Bookkeeping becomes more detailed |
| Can support a more structured approach to retirement savings and benefits through payroll | Some states add their own taxes, fees or filings |

Is an S Corp right for you?
The IRS doesn’t set an income requirement for electing S Corp status, so the answer depends on your business. If tax savings are your main motivator, the election makes sense when the savings potential is greater than the cost of the extra work, including payroll, bookkeeping and a business tax return. For a closer look at where that tends to happen, see Is an S Corp worth it?
In general, an S Corp may be worth exploring if you:
- Have steady, consistent profit rather than income that swings widely year to year.
- Have been self-employed long enough to feel confident the business will continue.
- Are ready to run payroll and keep more detailed books, or to get support with both.
On the other hand, staying with your default setup may make more sense if your business is new, your profit is modest or unpredictable, or your state treats S Corps less favorably.

Common S Corp myths and misconceptions
Because the term comes up so often, a few misconceptions tend to follow it. Here are the questions we hear most, and what’s actually true. For more, our S Corp FAQ answers 50 of the most common questions.
Is an S Corp a separate business from my LLC?
No. Your LLC stays the same legal entity, with the same state registration and liability protection. Instead, the S Corp election only changes how the IRS taxes it.
Are S Corps only for large companies?
No. In fact, many S Corps are one-person businesses. The election works for small businesses of any size, as long as every owner is eligible.
Is electing S Corp status a red flag with the IRS?
No. The S Corp is a standard election that the tax code has offered small businesses since 1958, and the IRS has clear rules for it. What draws IRS attention, by contrast, is not following those rules, such as taking distributions without paying yourself a reasonable salary.
Do S Corp owners still pay Social Security and Medicare taxes?
Yes. However, you pay them through payroll on your salary instead of as self-employment tax on all of your profit.
Can S Corp owners pay themselves a very low salary?
No. The IRS requires a reasonable salary for the work you do before you take distributions. As a result, your salary should reflect what similar businesses pay for similar work.
Are S Corp distributions tax-free?
Not entirely. Distributions avoid payroll taxes, but you still pay income tax on your share of the business’s profit.
Is an S Corp election permanent?
No. You can revoke an S Corp election. That said, re-electing soon after generally requires IRS consent, so it’s worth deciding carefully.
The bottom line on S Corps
Ultimately, an S Corp is a tax election that changes how the IRS taxes your business and how you pay yourself, not a new business you form. For many self-employed people with steady profit, it can be a meaningful step forward. However, it also brings payroll, more detailed books and new filings, so it works best when you have systems in place to support it.
