If you run your own business, at some point someone tells you to set up an S-Corp and save on taxes. It sounds like a quick switch that drops money back in your pocket. The real story has a few more moving parts, and the answer depends on how much you earn and how you want to run things. Let’s walk through what these two are and where the savings come from.
What an LLC Actually Is
An LLC is a legal structure, not a tax structure. That trips up a lot of people. When you form an LLC with your state, you get liability protection, which keeps your personal assets separate from the business. For taxes, though, the IRS does not have a box called “LLC.” By default, a one-owner LLC gets taxed as a sole proprietorship, and a multi-owner LLC gets taxed as a partnership.
How an LLC gets taxed by default
With the default setup, all of your business profit flows to your personal return. You pay income tax on it, and you also pay self-employment tax, which runs 15.3% on the first chunk of earnings (12.4% for Social Security plus 2.9% for Medicare). That self-employment piece is where the pain shows up, because it applies to your full profit, not just what you pay yourself.
What an S-Corp Actually Is
Here is the part that confuses people. An S-Corp is also a tax election, not a separate kind of company you form at the courthouse. You can have an LLC that is taxed as an S-Corp. You file Form 2553 with the IRS, and from that point your business gets treated differently for tax purposes while staying an LLC on paper.
The salary & distribution split
Once you elect S-Corp status, you have to pay yourself a reasonable salary through payroll. That salary gets hit with the 15.3% payroll taxes. The rest of the profit can come to you as a distribution, and distributions skip that 15.3%. That gap is the whole reason people talk about S-Corp savings.
Say your business clears $120,000 in profit. As a default LLC, the full $120,000 faces self-employment tax. As an S-Corp, you might pay yourself a $60,000 salary and take the other $60,000 as a distribution. You save the 15.3% on that $60,000, which lands around $9,000 back in your pocket.
Where the Savings Get Eaten Up
The math above looks great until you add the costs that come with an S-Corp. This is the part the “just set up an S-Corp” crowd skips over.
Payroll & filing costs
Running payroll for yourself is not free. You need a payroll system, you file quarterly payroll reports, and you file a separate business return (Form 1120-S) on top of your personal one. The bookkeeping load goes up too. Add it all up and you are often looking at a few thousand dollars a year in extra admin.
The reasonable salary rule
You cannot pay yourself a $10,000 salary and take $110,000 as a distribution to dodge the tax. The IRS expects the salary to match what someone doing your job would earn. Pay yourself too little and you invite an audit, plus back taxes and penalties. The salary has to hold up.
A Simple Way to Find the Break-Even
So when does the S-Corp election start to pay off? A rule a lot of people lean on: once your profit sits somewhere around $60,000 to $80,000 a year and stays there, the tax savings tend to outrun the added costs. Below that, the payroll and filing expenses can wipe out the benefit, and you end up doing more paperwork for nothing.
It also rides on how steady your income is. A business that swings from year to year is harder to plan around than one that earns a predictable amount.
Other Things That Tip the Decision
Taxes are not the only factor.
Retirement & benefits
Both setups let you open retirement accounts, but the salary you run through an S-Corp can change how much you are allowed to put away in certain plans. That matters if you want to save a lot for retirement.
Your own time & patience
Some owners are fine handling payroll and a second return. Others want the lightest setup so they can focus on the work itself. There is no shame in keeping things simple if the savings are thin.
Making the Call
The honest answer to which one saves more is that it depends on your numbers. A default LLC keeps life easy and costs little to maintain, which fits newer or lower-earning businesses. An S-Corp election can cut your tax bill once profits climb high enough to cover the added costs, but it asks more of you in paperwork and payroll.
The move that pays off is running your real profit through both scenarios before you file any forms. Plug in your income, subtract a fair salary, and compare the self-employment tax you would owe each way against the cost of running an S-Corp. If the gap clearly favors the S-Corp, switch. If it is close, the simpler path usually wins.
Sit down with someone who can model it on your specific income before you commit. The election is easy to make and harder to undo, so get the numbers right the first time.
