Legal & IP Basics
Thinking about electing S corp taxation for your LLC? See where the tax savings come from, the reasonable-salary rule, the costs, and when to skip it.

You formed an LLC, and now someone (an accountant, a founder friend, a video that autoplayed at 2 a.m.) is telling you to elect S corp status and stop overpaying taxes. Before you file anything, it helps to know what you are actually choosing. The real S corp benefits over an LLC come down to one thing: how the profit you already earn gets taxed.
An S corp is not a different company you go and start. It is a tax election your existing LLC can make. So the question is not "LLC or S corp" the way you pick a business name. You keep your LLC, and you decide whether to have it taxed under the S corporation rules. Whether that saves you money depends on how much your business earns, how much of the work you personally do, and how much added complexity you are willing to run.
This trips up almost everyone. S corporation status is not an entity type you register with your state. It is a federal tax classification, and when you elect it, your LLC stays an LLC. The state still sees the same company. Only the way the profit is taxed changes.
You make the switch by filing Form 2553 with the IRS. Nothing about your company's legal form changes, so you keep the same liability protection and the same operating agreement you already have. There is a filing window tied to the start of your tax year, and missing it can push the election to the following year unless you qualify for late-election relief, so this is a deadline worth marking early.
By default, the IRS treats a single-member LLC as a disregarded entity and a multi-member LLC as a partnership, with the profit flowing straight to the owners' personal returns. An LLC can instead elect to be taxed as a corporation, and a qualifying LLC that elects S corp treatment files an 1120-S return while keeping its LLC shell intact.
If you are still weighing the underlying entity itself, that is a different question from the tax election. It is covered in LLC vs Inc and the guide to moving on from a sole proprietorship.
The entire appeal is self-employment tax. When your LLC is taxed the default way, you owe self-employment tax on all of your net earnings from the business. That tax is 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare, and it sits on top of your regular income tax. On a healthy profit, that is a real bite before income tax even enters the picture.
An S corp election changes how you pay yourself. Instead of every dollar of profit counting as self-employment earnings, you split your take into two buckets: a salary that runs through payroll, and a distribution of the remaining profit. The salary carries the usual Social Security and Medicare taxes. The distribution does not carry self-employment tax. That gap is where the savings live.
Picture a founder whose business nets $120,000. Taxed as a default LLC, all $120,000 is exposed to self-employment tax. As an S corp, that same founder might run a salary of $70,000 through payroll and take the remaining $50,000 as a distribution, sparing that portion from the 15.3% layer. The catch is that you do not get to invent the salary number, which brings us to the rule that governs the whole strategy.
The IRS knows the salary-versus-distribution split is exactly where owners are tempted to game the system, so it built a guardrail: reasonable compensation. Before you take any profit out as a distribution, an S corp has to pay a shareholder who works in the business a fair wage for the work they actually do.
There is no magic percentage. The IRS points to factors like your training and experience, your duties, the time and effort you put in, and what comparable businesses pay someone for the same role. Pay yourself a token $12,000 salary on $200,000 of profit to dodge payroll tax, and you are inviting the IRS to reclassify those distributions as wages, with back taxes and penalties attached. A defensible salary is the price of admission for the distribution savings, not an optional detail.
The savings only matter if they clear the cost of capturing them. Running payroll, filing a separate return, and paying for more bookkeeping is not free, so a small sliver of distribution does not justify the switch.
You will hear a commonly cited rule of thumb: the math often starts to favor an S corp once your business nets somewhere in the range of $40,000 to $80,000 in profit above a reasonable salary. Treat that as a starting point for a conversation, not a line that is true for everyone. Your state's taxes, your salary level, your benefits, and your specific numbers all move where the line sits. This is the moment to run your actual figures with a CPA rather than a blog post or a free online calculator, because the difference between a good election and an expensive one is in the details.
An S corp election is not a set-and-forget checkbox. It brings ongoing obligations a default LLC does not have:
None of this is a reason to avoid the election. It is a reason to confirm the savings are large enough to be worth the extra work and expense before you commit.
For plenty of businesses, staying a default LLC is the smarter call:
The S corp election is a tax optimization, not a growth strategy or a status symbol. It rewards a specific situation: a profitable business, an owner who takes real money out, and enough margin above a reasonable salary to outrun the added costs. It does little for a business that is not there yet, and it can quietly cost you if you elect it too early. The separate question of how the two corporate tax classifications compare is covered in S corp vs C corp, which matters most once you are raising outside money.
Because this is tax law and your situation is specific, treat everything here as general education rather than advice for your business. The owners who get the most out of the election are the ones who modeled it with a CPA first, using their real revenue, a salary they can defend, and their own state's rules.
