LLC Tax Elections Explained: Default, S-Corp, and C-Corp — With Real Numbers

Most people forming an LLC focus on the legal side — limited liability, privacy, protecting their personal assets. And those things matter. But here's something a lot of new business owners don't realize until it's too late: the IRS gives you a choice about how your LLC is taxed. You don't have to accept the default.

That choice can be worth thousands of dollars a year. Or, if made at the wrong time or for the wrong reason, it can cost you. Understanding your options — and knowing when each one makes sense — is one of the most valuable things you can do in your first year of business.

This guide walks through all three LLC tax classifications: the default pass-through treatment, the S-Corp election, and the C-Corp election. We'll use real numbers, explain the IRS forms involved, and give you a clear framework for thinking through the decision. By the end, you'll know enough to have a productive conversation with your CPA — even if you're starting from zero.

What Is LLC Tax Classification?

The IRS doesn't have a special "LLC tax category." An LLC is a state-law creation — it tells the world who's liable for the business's debts. But for federal income tax purposes, the IRS needs to know: should this business be taxed like a sole proprietorship, a partnership, a corporation?

The answer depends on your LLC's structure and whether you've filed an election. The IRS's "check-the-box" regulations (Treasury Regulation §301.7701) give most LLCs the flexibility to be taxed as one of four entity types: a disregarded entity, a partnership, an S corporation, or a C corporation. The default rules cover the first two automatically. The elections cover the last two.

Here's the key insight: your legal structure and your tax structure are separate things. A Wyoming LLC can be taxed as an S corporation. It's still an LLC under state law — with all of Wyoming's privacy and asset protection benefits intact. The S-Corp designation is purely a federal income tax classification.

Default Tax Treatment: How LLCs Are Taxed Without an Election

If you form an LLC and don't file any special elections, the IRS automatically applies the default rules. What those rules are depends on how many members your LLC has.

Single-Member LLC: The Disregarded Entity

A single-member LLC is automatically treated as a disregarded entity for federal tax purposes. "Disregarded" means the IRS ignores the LLC as a separate entity — the business's income and expenses flow directly to your personal return, as if the LLC doesn't exist at all for tax purposes.

In practice, this means you report your LLC's profit and loss on Schedule C of your personal Form 1040. If your business made $80,000 in profit this year, that $80,000 shows up on your personal return.

Here's where it gets expensive: as a Schedule C filer, all of that net profit is subject to self-employment (SE) tax. Self-employment tax covers Social Security and Medicare — the same taxes that employees split with their employers. But when you're self-employed, you pay both halves. The current SE tax rate is 15.3% on the first $176,100 of net self-employment income (2025 threshold; the Social Security wage base adjusts annually), and 2.9% above that.

That's over $11,000 in self-employment tax before you've even touched federal income tax. The SE tax is the reason that high-earning LLC owners start paying attention to elections.

Multi-Member LLC: Partnership Taxation

If your LLC has two or more members, the default treatment is a partnership. The LLC files an informational return on Form 1065, and each member receives a Schedule K-1 showing their share of the LLC's income, deductions, and credits.

Each member then reports their K-1 income on their personal return. Just like a single-member LLC, each member's share of the business's net profit is generally subject to self-employment tax if that member is actively participating in the business. (There are nuances for limited partners and passive members, but if you're working in the business, assume SE tax applies.)

The LLC itself pays no federal income tax — the profit passes through to the members, who pay tax at their individual rates. That's the "pass-through" in "pass-through taxation."

Wyoming's State Tax Advantage Starts Here

One of the reasons so many business owners form their LLCs in Wyoming is what happens at the state level. Wyoming has no state income tax. For LLC owners using pass-through taxation, that means zero state tax on business income at the Wyoming level. Compare that to California (up to 13.3% state income tax) or New York City (additional city income tax on top of state rates) and the advantage compounds quickly — regardless of which federal election you make.

The S-Corp Tax Election: How It Works and What It Saves

The S-Corp election is the most commonly discussed LLC tax strategy, and for good reason. When done correctly, at the right income level, it can meaningfully reduce your self-employment tax burden. Here's the mechanics.

What the S-Corp Election Actually Does

When you elect S-Corp status by filing Form 2553 with the IRS, your LLC is no longer treated as a disregarded entity or partnership. Instead, it's treated as an S corporation for federal tax purposes. The LLC still exists under Wyoming state law — all your privacy and asset protection benefits remain exactly as they were. The S-Corp designation is purely a federal income tax classification.

Under S-Corp taxation, you (as the owner-employee) must pay yourself a reasonable salary for the work you do in the business. That salary is processed through payroll — you withhold income tax, and both the employee and employer halves of FICA (Social Security and Medicare) taxes are paid. This part is the same as any regular employee's paycheck.

Here's where the potential SE tax reduction comes in: any profits above and beyond your salary can be taken as owner distributions. Distributions are not subject to self-employment or FICA taxes. They're still taxable income — you pay ordinary income tax on them — but the 15.3% SE tax does not apply to that portion of the profit.

The S-Corp Savings: A Concrete Example

In this illustrative example, the potential reduction in employment tax is roughly $5,000 — before accounting for any additional payroll costs. As profit grows, the gap between the salary portion and total profit widens, which may further reduce SE tax exposure. On $150,000 in profit with a $60,000 salary, the difference in employment taxes in this type of example can be significant. Actual results depend on your individual situation.

These numbers are illustrative. Actual tax outcomes depend on your profit level, what constitutes a "reasonable salary" in your field, your payroll processing costs, and your overall tax situation. Tax outcomes depend on your individual circumstances. A CPA can model the specific numbers for your business.

The Catches: What S-Corp Status Requires

The S-Corp election is not free money. It comes with real requirements and costs that you need to factor into the decision:

• Payroll is mandatory. You must run actual payroll for yourself — W-2 wages, withholding, quarterly deposits to the IRS (Form 941), and annual W-2 filing. A payroll service (Gusto, ADP, QuickBooks Payroll) typically costs $50–$150 per month for a single-person S-Corp. That's $600–$1,800 per year in recurring cost that offsets any potential reduction in SE tax obligations.
• Annual S-Corp tax return. The LLC must file Form 1120-S annually (in addition to your personal 1040). Accountants typically charge $500–$1,500 to prepare an S-Corp return, more than a basic Schedule C return. Some CPA firms bundle the 1120-S into your overall accounting package.
• Reasonable compensation rules. The IRS requires that owner-employees pay themselves a "reasonable" salary — meaning an amount comparable to what the business would pay an arm's-length employee to do the same work. Paying yourself $1 while taking $200,000 in distributions is an audit trigger. If the IRS reattributes distributions as wages, you'll owe back taxes, penalties, and interest. Your CPA can help you establish a defensible salary.
• Deadline: Form 2553 must be filed on time. For new LLCs, the election must be filed within 75 days of formation (or within 75 days of the start of the tax year you want it to apply to). For existing LLCs switching to S-Corp status, the deadline is March 15 to take effect for the current calendar year. Missing the deadline means waiting until the following year — which is why many new business owners have their formation service file the 2553 at the same time they form the LLC.
• S-Corp eligibility requirements. Your LLC must have 100 or fewer members, all members must be U.S. citizens or resident aliens, and there can only be one class of membership interest. Most small single-owner or small partnership LLCs qualify easily, but it's worth confirming.

When an S-Corp Election Makes Sense

The rough consensus among tax professionals is that the S-Corp election starts to make financial sense when your net business profit reaches approximately $50,000 to $75,000 per year. Below that threshold, the payroll costs, accounting fees, and administrative complexity often eat up more than you save in SE tax.

Above $75,000 in annual profit, many business owners find that the S-Corp election may produce meaningful net reductions in self-employment tax — depending on payroll costs, salary level, and individual circumstances. The wider the gap between your reasonable salary and total profit, the greater the potential reduction in SE tax exposure.

The election may not be right for you even above those thresholds if:

• You want to retain most of the business's profits inside the company (distributions are taxed when taken, but retained earnings are still subject to income tax in an S-Corp)
• You prefer to avoid running payroll for simplicity's sake
• You have passive investors or members who don't qualify under S-Corp eligibility rules

The C-Corp Tax Election: Double Taxation, and When It's Worth It

The C-Corp election is the least common path for small business LLCs — and for good reason. But there are specific situations where it makes genuine sense, and understanding those situations will help you know when to consider it.

How C-Corp Taxation Works

To elect C-Corp status, an LLC files Form 8832 (Entity Classification Election) with the IRS. Once elected, the LLC is taxed as a C corporation for federal income tax purposes.

Under C-Corp taxation, the corporation itself pays federal income tax at the flat 21% corporate rate (as established by the Tax Cuts and Jobs Act of 2017). After-tax profits distributed to owners as dividends are then taxed again as personal income — at qualified dividend rates (0%, 15%, or 20% depending on your income bracket).

This is the "double taxation" that makes C-Corp status generally unappealing for small businesses. A dollar earned in a C-Corp might be taxed at 21% at the entity level, and then at 15–20% again when distributed. Compare that to pass-through taxation where profits are only taxed once, at the owner's personal rate.

When C-Corp Status Can Make Sense

Despite the double-taxation drawback, certain situations legitimately favor C-Corp treatment:

• Raising venture capital or institutional investment. Most VC firms require a C-corporation structure (usually a Delaware C-corp) as a condition of investment. They need a corporate entity that can issue preferred stock, convertible notes, and standard equity instruments. If you're pursuing institutional funding, the C-Corp structure is often a practical necessity rather than a tax choice.
• Issuing equity compensation to employees. Stock options, restricted stock units (RSUs), and other equity incentives are cleaner to implement in a C-Corp. ISO (incentive stock option) rules under IRC Section 422 specifically require a corporation structure. If attracting talent with equity is central to your growth plan, C-Corp status facilitates that.
• Retaining significant earnings inside the business. If your goal is to reinvest most of the business's profits back into operations and you don't need to take distributions, the 21% corporate rate may be lower than your personal marginal tax rate. For a business owner in the 37% federal bracket who reinvests most of their profits, paying 21% at the entity level rather than 37% personally can be attractive — at least until funds are eventually distributed.
• Owner-employee fringe benefits. C-Corp owner-employees can receive certain fringe benefits — including employer-paid health insurance, group term life insurance, and dependent care assistance — as tax-free compensation. In S-Corps and pass-through entities, these benefits are generally included in the owner's taxable income. This advantage is narrower than it used to be, but still meaningful for certain benefit-heavy situations.
• Qualified Small Business Stock (QSBS) — Section 1202. This is a niche but potentially powerful benefit. Under IRC Section 1202, shareholders who acquire stock in a "qualified small business" C-corporation and hold it for more than five years may be able to exclude up to 100% of capital gains on a sale — up to $10 million (or 10 times their basis). The exclusion has income and other qualifications, but for founders building toward an acquisition, the potential tax reduction can be substantial depending on individual circumstances. This exclusion is not available for S-Corp or pass-through LLCs.

Important Cautions About C-Corp Election

A few things to know before considering the C-Corp path:

• Converting back is a taxable event. If you elect C-Corp status and later want to switch to S-Corp or back to pass-through, the conversion can trigger significant tax consequences. The IRS treats the conversion as if you sold all of the C-Corp's assets at fair market value. This "built-in gains" issue can result in a large, unexpected tax bill. C-Corp elections are much easier to make than to undo.
• Accumulated Earnings Tax. The IRS assesses an additional 20% penalty tax on C-Corps that accumulate earnings beyond what the business reasonably needs — specifically to avoid paying dividends to shareholders. This limits the "leave money in the company" strategy if it's being used purely to avoid dividend tax rather than for legitimate business purposes.
• State tax complications. Even though Wyoming has no state income tax, a C-Corp doing business in other states may owe corporate income tax in those states. California, for example, charges an 8.84% corporate income tax on income earned in California, regardless of where the corporation is formed.

The bottom line: the C-Corp election is rarely the right choice for a new small business generating primarily active income. It's a specialized tool for specific situations — primarily around investment capital, equity compensation, and long-term exit strategies.

Which Tax Election Is Right for You? A Decision Framework

With all three options on the table, here's a practical framework for thinking through the decision. This is designed to help you walk into a conversation with your CPA already knowing what questions to ask.

A few additional considerations that often get left out of these conversations:

The default is always the starting point, never the wrong answer. If you form your LLC today and don't know which election to make, defaulting to pass-through taxation is perfectly fine. You're not leaving money on the table if your profit is still building. You can elect S-Corp status in a future year by filing Form 2553 by March 15 of the year you want it to apply.

Payroll costs matter in the S-Corp calculation. The savings estimate above assumed no incremental payroll processing cost. In reality, if you're paying $1,200/year for payroll software and $1,500 more for your accountant to prepare the 1120-S, those costs reduce your net savings. For some business owners at the $50K–$60K profit level, the net benefit after expenses is minimal. For others at $100K+, it's substantial even after accounting for the additional compliance costs.

State taxes are separate from federal elections. Electing S-Corp or C-Corp status at the federal level doesn't automatically determine your state tax treatment. Some states honor the federal S-Corp election; others have their own filing requirements or charge a separate S-Corp fee. Wyoming doesn't levy additional taxes on S-Corps or impose a minimum fee. Your state of residence may be different — confirm with your CPA.

These elections can affect your financial picture beyond taxes. S-Corp owner-salaries affect Social Security benefits calculations at retirement (you're earning "covered wages"), and can affect your ability to contribute to certain retirement accounts. Think holistically, not just about this year's tax bill.

Wyoming's Tax Advantages Apply to Every Election

Here's something worth emphasizing: no matter which federal tax election you make, Wyoming's state-level tax environment works in your favor.

Wyoming charges zero state income tax — on individuals and on LLCs taxed as pass-throughs. If you're running a Wyoming LLC as a disregarded entity or S-Corp and you live in a state without income tax (Texas, Florida, Nevada, and others), you owe no state income tax anywhere on your business income. That's an advantage no federal election can replicate.

Compare that to forming an LLC in California, where you'd pay the state's 8.84% corporate income tax on C-Corp income, or up to 13.3% in personal income tax on S-Corp distributions. Or New York, which layers city income taxes on top of state rates. Wyoming has no state income tax — removing that layer entirely and creating a compounding advantage that grows with your income each year.

Even if you live in a state with income tax, forming your operating LLC in Wyoming and keeping your principal operations there as much as possible can meaningfully reduce your overall tax exposure. A CPA who works with multi-state businesses can help you structure this properly.

Wyoming is designed to support both tax efficiency and asset protection. Wyoming's charging order protection — among the strongest in the country — combined with zero state income tax means the state-level advantages apply regardless of which federal election you choose to make.

When to Talk to a CPA (Before You Do Anything)

This is not a section we're including just to cover ourselves legally. Talking to a CPA before making a tax election is genuinely important, and here's what a good one will actually help you figure out:

• Your realistic "reasonable salary" range. This is the hinge point of the entire S-Corp calculation. What do people in your industry, with your role, make? A salary that's too low is an audit risk; a salary that's too high reduces your savings. Your CPA can research comparables and help you document a defensible number.
• The actual net picture, after all costs. Payroll service fees, 1120-S preparation, your accountant's additional hours — all of these offset any potential SE tax reduction. Your CPA can model the true net outcome for your specific numbers and tell you whether the election pencils out.
• Timing. If you're near the 75-day window from your formation date, or approaching a March 15 deadline, a CPA can advise whether to file now or wait for the next year. Filing an S-Corp election retroactively requires meeting certain conditions.
• State-specific implications. Your CPA should review the state tax rules where you live and where your business operates, not just the federal picture.
• Retirement planning integration. The salary you pay yourself in an S-Corp affects Solo 401(k) and SEP-IRA contribution limits. A CPA can help you weigh potential near-term tax reductions against retirement contribution capacity over time.
• Whether a C-Corp election makes sense for your exit strategy. If you have a potential acquisition in your future, the QSBS exclusion under Section 1202 could be worth millions — but the timing and qualification requirements are strict. A CPA (often working alongside a tax attorney) can help you evaluate whether structuring for QSBS makes sense from day one.

The right time to talk to a CPA is before you make any election — ideally before you even form your LLC if you already know you'll be profitable. A one-hour consultation often costs between $150 and $400 and can save you far more in taxes or costly mistakes.
