You started an LLC, business is going well, and then someone at a networking event says the four words that ruin your evening: “You should be an S-Corp.” Now you are Googling at midnight, drowning in tax jargon, and not sure if you are leaving thousands of dollars on the table or about to create a payroll headache you do not need.
Here is the clarity you actually want. This guide breaks down what an LLC and an S-Corp really are, how each is taxed, the exact profit level where switching starts to pay off, and how to make the election without tripping over the IRS rules that got stricter in 2026. No fluff, just the decision.
First, the Thing Almost Everyone Gets Wrong
An LLC and an S-Corp are not two versions of the same thing, and comparing them head-to-head is a bit like comparing “a car” to “cruise control.” One is a legal structure. The other is a tax election.
An LLC (limited liability company) is a legal entity you form with your state. It separates your personal assets from your business. An S-Corp is not an entity you form at all. It is a tax status you elect with the IRS, and your existing LLC can keep everything about it the same and simply choose to be taxed as an S-Corp. That single distinction clears up ninety percent of the confusion.
What an LLC Actually Is
When you form an LLC, you get liability protection: if the business is sued or owes money, your house, car, and personal savings are generally shielded. It is cheap to start, light on paperwork, and flexible.
By default, the IRS ignores your LLC for tax purposes. A single-member LLC is taxed as a sole proprietorship, and a multi-member LLC is taxed as a partnership. In both cases the profit “passes through” to your personal tax return. You do not pay a separate corporate tax. You do, however, pay self-employment tax on every dollar of profit, and that is the pain point an S-Corp is designed to relieve.
What an S-Corp Actually Is
An S-Corp is a tax election. You keep your LLC (or you have a corporation) and file a form telling the IRS you want to be taxed under Subchapter S. Nothing about your logo, bank account, or contracts changes. What changes is how the profit is split and taxed.
As an S-Corp, you become an employee of your own business. You pay yourself a salary through payroll, and the leftover profit comes to you as a distribution. The salary is subject to payroll taxes. The distribution is not subject to self-employment tax. That gap is where the savings live.
How Each One Is Taxed (Where the Money Is)
How an LLC is taxed
With a default LLC, all of your net profit is hit with self-employment tax on top of regular income tax. For 2026 the self-employment tax rate is 15.3% (12.4% for Social Security and 2.9% for Medicare), calculated on 92.35% of your net earnings. The Social Security portion applies up to the 2026 wage base of $184,500. You do get to deduct half of the self-employment tax when figuring your income, which softens the blow a little, but the full 15.3% still lands on every dollar of profit.
On $120,000 of profit, that self-employment tax alone is roughly $16,900 before you even get to income tax. For a lot of owners, that number is the whole reason they are reading this article.
How an S-Corp is taxed
With an S-Corp, only your salary gets hit with the equivalent payroll taxes (Social Security and Medicare, split between you and the company but economically the same 15.3%). The distributions you take above your salary skip self-employment tax entirely. Income tax still applies to everything, salary and distributions alike, so the S-Corp does not dodge income tax. It only trims the payroll-tax bill.
A Real Example: $120,000 in Profit
Say your business nets $120,000 after expenses.
As a default LLC, you pay self-employment tax on essentially all of it, about $16,900. As an S-Corp, you might pay yourself a reasonable salary of $70,000 and take $50,000 as a distribution. Payroll taxes apply to the $70,000 (roughly $10,700), and the $50,000 distribution avoids the 15.3%. That is close to $6,000 saved in a single year, before subtracting the added costs of running an S-Corp.
Scale that up. At $180,000 of profit with a $90,000 salary, the savings can push past $12,000 a year. That is the math that makes the midnight Googling worth it, and it is also why the IRS watches this closely.
The “Reasonable Salary” Rule You Cannot Ignore
Here is the catch that ruins the strategy for people who get greedy. The IRS requires S-Corp owners to pay themselves a reasonable salary for the work they do before taking distributions. You cannot pay yourself $15,000 and call the other $105,000 a distribution. Your salary has to reflect what you would pay someone else to do your job.
In 2026 the IRS is using data-matching to flag S-Corps where distributions dwarf salaries, and getting caught means back payroll taxes, penalties, and interest. Pick a salary you could defend to an auditor. Look up market pay for your role, document how you landed on the number, and lean reasonable rather than aggressive. A tax pro earns their fee here.
When an S-Corp Election Actually Pays Off
The rough break-even in 2026 sits around $75,000 to $80,000 of net profit. Below that, the cost of payroll, bookkeeping, and a separate business tax return tends to eat up whatever you would save on self-employment tax.
Above it, the savings usually outrun the costs, and the higher your profit, the better the deal, up until distributions become unreasonable relative to a fair salary. If your business clears roughly $80,000 in profit and that profit is stable, the S-Corp conversation is worth having now, not next year.
The Costs and Hassle of an S-Corp
An S-Corp is not free money. It comes with real overhead you should price in before you elect.
You have to run actual payroll, which usually means a service like Gusto or QuickBooks Payroll and a cost of roughly $500 to $1,500 a year. You file a separate business return (Form 1120-S), so your tax prep bill climbs, often by $800 to $2,000. You need cleaner bookkeeping and a real business bank account to keep the salary-and-distribution split defensible. If you have not separated your money yet, start with the best business bank accounts for freelancers and LLCs, because clean books are what make an S-Corp survive scrutiny.
Add those numbers up, usually $2,000 to $4,000 a year, and compare them to your projected tax savings. If the savings clearly beat the costs, elect. If it is close, wait until your profit grows.
How to Elect S-Corp Status (Form 2553)
Electing is more manageable than it sounds. Keep your LLC, then file IRS Form 2553 to elect S-Corp taxation. For the election to apply to the current calendar year, you generally need to file by March 15. Miss it and you can often still get relief for a late election if you have a reasonable cause, but do not count on it, file on time.
Once elected, set up payroll, run your reasonable salary on a regular schedule, and keep distributions clearly separate from wages in your accounting. If tax structure feels over your head, this is exactly the kind of decision worth mapping out in a simple plan first, and our guide to writing a business plan that actually gets used can help you pressure-test the numbers before you commit.
Mistakes to Avoid
Do not elect S-Corp status too early. If you are netting $40,000, the overhead usually costs more than it saves. Do not lowball your salary to grab bigger distributions, because that is the fastest way to an audit. Do not forget the March 15 deadline. And do not mix personal and business money, because a blurry paper trail undoes the whole defense if the IRS asks questions.
So, Which One Should You Choose?
If you are earning under roughly $75,000 in profit, are just starting out, or want the least paperwork possible, stay a default LLC. It protects you, it is cheap, and it keeps your life simple.
If your profit is comfortably above $80,000, steady, and you can pay yourself a fair salary while still taking meaningful distributions, elect S-Corp status and capture the savings. The best move is not permanent either way. Plenty of owners run as a plain LLC for a few years, then flip on the S-Corp election the year their profit crosses the line. Run your real numbers, or have a tax pro run them, and let the math decide.
Two Tax Perks People Forget to Factor In
The self-employment savings get all the attention, but two other levers can tip the decision, and both are easy to overlook when you are staring at a single year’s numbers.
The QBI deduction cuts both ways
The Qualified Business Income (QBI) deduction lets many pass-through owners deduct up to 20% of qualified business income. Both default LLCs and S-Corps can qualify, but the way an S-Corp splits salary and distributions changes the math, because your wages are not counted as QBI. For some high earners in specified service fields, a well-set salary actually helps them stay inside the income limits and keep the deduction. This is genuinely worth modeling with a CPA, because a salary that is too high or too low can quietly cost you thousands in lost deductions.
Retirement contributions get bigger as an S-Corp
Once you are on payroll, a Solo 401(k) or SEP IRA lets you contribute both as an employee and as the employer. Because the employer contribution is tied to your W-2 wages, running a reasonable salary can unlock larger tax-advantaged retirement contributions than you might manage as a plain sole proprietor. If long-term wealth-building is part of your plan, that added contribution room is a real, recurring benefit, not a one-time trick.
LLC vs S-Corp at a Glance
Think of it this way. The LLC is your foundation: it gives you liability protection and simplicity no matter what. The S-Corp is an upgrade you bolt on when your profit is high enough to justify the payroll, bookkeeping, and extra return. Start as an LLC, watch your net profit, and the year it settles comfortably above $80,000, run the numbers on electing S-Corp status. You are not choosing one forever; you are choosing what fits your business this year.
Frequently Asked Questions
Is an S-Corp better than an LLC?
Neither is universally better. An LLC is a legal structure; an S-Corp is a tax election an LLC can make. For lower-profit businesses the plain LLC usually wins on simplicity and cost. Once profit is comfortably above about $80,000, the S-Corp election often saves thousands in self-employment tax.
At what income should I switch to an S-Corp?
The common break-even in 2026 is around $75,000 to $80,000 in net profit. Below that, payroll and extra filing costs tend to cancel out the savings. Above it, the tax savings usually outrun the overhead.
Do I have to close my LLC to become an S-Corp?
No. You keep your LLC exactly as it is and file Form 2553 to have it taxed as an S-Corp. Your bank account, contracts, and branding all stay the same.
What is a reasonable salary for an S-Corp owner?
It is what you would pay someone else to do your job, based on your role, experience, and industry. The IRS expects your salary to be defensible, so research market rates and document your reasoning rather than picking the lowest number possible.
When is the deadline to elect S-Corp status?
To apply for the current calendar year, you generally must file Form 2553 by March 15. Late elections are sometimes granted with reasonable cause, but filing on time is far safer.
