S-Corp status is a tax election — not a business structure. It lets you split your income into a salary and owner distributions, so payroll tax only applies to the salary portion. At higher incomes, that split can save thousands per year. Below roughly $80,000 in net income, the costs outweigh the savings.
What an S-Corp actually is
First, a common source of confusion: S-Corp is not a type of business entity. It's a tax status — specifically, an election you make with the IRS to have your business taxed as an S Corporation under Subchapter S of the Internal Revenue Code.
Most 1099 contractors who elect S-Corp status first form an LLC at the state level, then file IRS Form 2553 to elect S-Corp taxation. The LLC provides the legal liability protection. The S-Corp election changes how the IRS taxes the income that flows through it.
Without the S-Corp election, a single-member LLC is a "disregarded entity" — all income flows to your personal return as self-employment income, and you pay the full 15.3% SE tax on all of it. With the S-Corp election, you pay yourself a reasonable salary through payroll, and take the remainder as owner distributions. Only the salary is subject to payroll tax. Distributions are not.
"An LLC is legal protection. An S-Corp election is a tax decision. They are different things layered on top of each other."
— The distinction that trips up most contractors considering this move
How the tax savings actually work
The self-employment tax rate is 15.3% — 12.4% Social Security plus 2.9% Medicare — applied to 92.35% of your net self-employment income. As a sole proprietor or single-member LLC, you pay this on everything you earn.
Under an S-Corp, you pay yourself a salary and take the rest as distributions. The salary goes through payroll and is subject to payroll tax — the employer and employee halves of FICA. The distributions skip payroll tax entirely. The tax savings come from that gap.
This is the same math the calculator on the homepage runs in the S-Corp section — using a 60/40 salary-to-distribution split as a starting estimate. Your actual split depends on what the IRS considers "reasonable compensation" for your role, which is a fact-specific determination.
The $80,000 threshold — why it exists
Running an S-Corp isn't free. You need payroll software or a payroll service, a more complex annual tax return (Form 1120-S plus your personal return), and usually a CPA who understands S-Corps. Those costs typically run $2,000–$5,000 per year depending on how much help you hire.
Below a certain income level, the SE tax savings don't exceed those costs. The commonly cited threshold is around $80,000 in net self-employment income — at which point the gross SE tax savings start to meaningfully outrun the administrative overhead.
| Net SE income | Estimated SE tax saved (60/40 split) | Typical admin cost | Net benefit |
|---|---|---|---|
| $60,000 | ~$2,760 | ~$3,000 | −$240 (not worth it) |
| $80,000 | ~$3,680 | ~$3,000 | ~$680 (borderline) |
| $100,000 | ~$4,600 | ~$3,000 | ~$1,600 |
| $150,000 | ~$7,450 | ~$3,000 | ~$4,450 |
| $200,000 | ~$9,200 | ~$3,000 | ~$6,200 |
These are simplified estimates using a flat 60/40 split and $3,000 in admin costs. Your actual numbers depend on your specific salary determination, your state, and what you pay for payroll and accounting. Use the calculator on the homepage to run your specific income through the S-Corp analysis.
The "reasonable compensation" requirement
This is the part most guides gloss over, and it's the part that gets S-Corp owners into trouble with the IRS. You cannot simply minimize your salary to maximize distributions and pocket the payroll tax savings. The IRS requires that S-Corp owner-employees pay themselves reasonable compensation — a salary that reflects what you'd pay someone else to do the same work.
What makes compensation "reasonable" is fact-specific: your industry, your role, your geographic market, your company's revenue. The IRS scrutinizes situations where an S-Corp owner pays themselves very little in salary relative to distributions, because that's the obvious way to game the system.
The 60/40 salary-to-distribution split used in the calculator is a common starting point and is defensible for many situations — but it's not a rule. Some CPAs use 50/50 for higher earners. Others use 70/30 for service-heavy businesses. The right number is one a CPA who knows your industry would sign off on.
The IRS has reclassified distributions as wages in audit cases where the salary was unreasonably low. This triggers back payroll taxes, penalties, and interest. Reasonable compensation is not optional — it's an IRS requirement with real enforcement consequences.
What S-Corp status actually costs to run
The ongoing costs are real and often understated in "S-Corp saves you money" articles. Here's what you're actually signing up for:
- Payroll processing — You're now an employee of your own company. You need to run payroll, withhold payroll taxes, and remit them to the IRS and your state on a regular schedule. Payroll software like Gusto or a full-service payroll provider runs $50–$150/month for a single employee.
- Additional tax return — Your S-Corp must file Form 1120-S annually. This is separate from your personal 1040 and typically adds $500–$1,500 to your CPA's fee, depending on complexity.
- State filing fees and franchise taxes — Many states charge annual fees or franchise taxes for S-Corps that don't apply to sole proprietors. California charges a minimum $800/year. New York, Texas, and others have their own requirements.
- CPA fees — Running an S-Corp correctly essentially requires a CPA. If you're not currently using one, budget $1,500–$3,000/year for a CPA who specializes in self-employed clients.
- Registered agent — If your LLC requires a registered agent in your state, that's typically $50–$150/year.
Total real-world annual overhead: typically $2,500–$5,000/year for a solo contractor running a clean, simple operation. That's your break-even hurdle for the SE tax savings to be worth it.
LLC vs S-Corp — the actual decision
These two things address different questions entirely:
| Question it answers | LLC | S-Corp election |
|---|---|---|
| Legal liability protection | Yes | No — that's the LLC's job |
| Reduces self-employment tax | No | Yes — at sufficient income |
| Requires annual state filing | Usually yes | Yes — more complex |
| Requires payroll | No | Yes — you must pay yourself |
| Can be combined | Yes — LLC + S-Corp election is the standard approach | |
The typical path: form an LLC first to get liability protection, then elect S-Corp status once your income crosses the threshold where it makes financial sense. An LLC without an S-Corp election is taxed as a sole proprietor by default — you get the legal protection without the payroll complexity.
How to make the S-Corp election
File Articles of Organization with your state's Secretary of State. Fees range from $50 to $500 depending on the state. You'll also need an Operating Agreement and, typically, a registered agent. A service like Collective handles this for you, or you can do it directly through your state's portal.
Apply at IRS.gov — it's free and takes about 10 minutes. You'll need this to open a business bank account, run payroll, and file business tax returns. Do this before filing the S-Corp election.
File Form 2553 with the IRS to elect S-Corp taxation. For the election to apply to the current tax year, you must file within 75 days of forming your entity, or by March 15 for the election to apply to that calendar year. Late elections are possible but require IRS approval. Your CPA or a service like Collective handles this filing.
Once you're an S-Corp, you must run payroll for yourself as an employee. Set up a payroll service, determine your reasonable compensation, and start paying yourself on a regular schedule. Gusto and Collective both handle this for solo S-Corp owners.
The S-Corp must have its own bank account separate from your personal finances. Commingling funds is one of the fastest ways to invite IRS scrutiny. Keep salary payments and distributions clearly documented and separate.
Your S-Corp files its own tax return (Form 1120-S) by March 15 each year. This generates a Schedule K-1 that flows to your personal 1040. Your CPA handles this — it's not something to DIY unless you have a strong tax background.
Timing the election — what most contractors get wrong
The S-Corp election has strict timing rules that catch a lot of contractors off guard:
- For a new entity: You must file Form 2553 within 75 days of formation for the election to apply from day one.
- For an existing LLC: To elect S-Corp status for the current calendar year, you must file by March 15 of that year. Miss that deadline and the election applies to the following year.
- Late election relief: The IRS has a late election procedure that allows you to retroactively elect S-Corp status in some cases, but it requires showing "reasonable cause" and isn't guaranteed. Don't count on it as a fallback.
The practical implication: if your income is crossing the threshold mid-year and you want the S-Corp election to apply to the current year, move quickly. Talk to a CPA before the March 15 deadline, not after.
Who the S-Corp election is actually right for
The S-Corp election makes the most sense for contractors who meet all of the following criteria:
- Net self-employment income consistently above $80,000–$100,000. The savings need to outrun the costs year after year, not just in a good year.
- Relatively stable, predictable income. The payroll requirement means you're committing to regular salary payments. If your income is highly variable, managing payroll through slow months adds complexity.
- Working primarily in one state. Multi-state S-Corps are significantly more complex and expensive. If you're working across state lines, the calculus changes.
- Comfortable with some administrative overhead — or willing to pay someone else to handle it. This isn't a "set it and forget it" structure.
- Planning to stay self-employed for the foreseeable future. The setup costs don't make sense if you're likely to return to W2 employment within a year or two.
Tools built for S-Corp contractors
Running an S-Corp correctly requires at minimum a payroll solution and ideally a CPA who specializes in self-employed clients. These are the two platforms we've seen work best for solo contractors:
Collective handles LLC formation, the S-Corp election filing, monthly bookkeeping, payroll, and annual business tax filing — all under one flat monthly membership with a dedicated bookkeeper and CPA on your account. You're not assembling four separate services or explaining your situation from scratch every quarter. Everything connects, and someone who knows your file is always there.
The honest trade-off: it costs more than running payroll software alone. If you're just above the $80k threshold, run the math carefully. But if your income is solidly in S-Corp territory, it tends to pay for itself and then some.
If you'd rather manage your own bookkeeping and just need payroll done right, Gusto is the most contractor-friendly payroll platform available. Payroll taxes filed automatically in all 50 states, built-in reasonable salary benchmarking, and W-2 and 1099 payments in one place.

Common questions
Can I elect S-Corp status without forming an LLC first?
Yes — you can elect S-Corp status as a sole proprietor by incorporating as a C-Corp and then making the S-Corp election. But the LLC-then-S-Corp election path is far more common for solo contractors because it's simpler, cheaper, and provides the same liability protection with less formality than a C-Corp.
What happens if I elect S-Corp and then my income drops?
You can revoke the S-Corp election, but the process has timing rules similar to the election itself. More importantly, revoking it doesn't eliminate the administrative costs you've already incurred for that year. If your income is variable, this is a reason to be conservative about when you elect — do it when you're confident the income level will persist, not after a single good year.
Do S-Corps pay self-employment tax?
The S-Corp entity itself doesn't pay SE tax. The salary you pay yourself through payroll is subject to FICA (payroll tax), which is the equivalent — but only on the salary portion, not on distributions. That's the whole point of the structure.
Should I form an LLC or elect S-Corp status?
An LLC is primarily about legal liability protection — it doesn't change how you're taxed by default. An S-Corp election is a tax status you layer on top, and it only makes financial sense once your net self-employment income is high enough that the SE tax savings outweigh the added payroll and accounting costs. The two are complementary, not alternatives — most contractors who go this route do both.
