Once a business starts making real money, one tax question comes up again and again: should it be taxed as an S-corp? This is one of the most misunderstood topics in small business, partly because “LLC” and “S-corp” get talked about as if they’re the same kind of thing. They aren’t. An LLC is a legal structure; an S-corp is a tax election that certain businesses can choose. Understanding the difference — and the payroll-tax savings the S-corp election can offer — can save a profitable business real money, or waste time and fees if chosen too early. This guide explains what the election actually is, how the savings work, and when it makes sense.
Structure vs Tax Election
Here’s the key distinction. An LLC is a legal entity that gives you liability protection and flexibility. By default, a single-member LLC is taxed like a sole proprietorship and a multi-member LLC like a partnership — meaning all the profit is subject to self-employment tax. An S-corp, by contrast, isn’t a separate kind of company you form; it’s an election you make with the IRS about how your business is taxed. An LLC can elect to be taxed as an S-corp while remaining an LLC. So the real question isn’t “LLC or S-corp?” — it’s “should my LLC (or corporation) elect S-corp tax treatment?”
How the S-Corp Election Saves on Taxes
The appeal is self-employment (payroll) tax savings. As a default LLC, essentially all of your net profit is hit with self-employment tax (the Social Security and Medicare portion) on top of income tax. With an S-corp election, you split your income into two buckets: a reasonable salary you pay yourself (which is subject to payroll taxes) and the remaining profit as distributions (which are not subject to self-employment tax). Because only the salary portion gets hit with payroll tax, an owner taking a reasonable salary plus distributions can pay less self-employment tax than they would as a default LLC. That’s the entire mechanism — and it only produces meaningful savings once profits are high enough.
The Catch: Reasonable Salary and Extra Costs
The savings come with strings. The IRS requires that your salary be reasonable for the work you do — you can’t pay yourself a tiny salary and take everything else as distributions to dodge payroll tax; that invites trouble. An S-corp also adds administrative burden and cost: you have to run actual payroll, file a separate business tax return, and often pay for more bookkeeping and a tax professional. Those added costs — often a meaningful yearly amount — eat into the savings. That’s why the election rarely pays off for a business with modest profit; the overhead can exceed the tax saved.
When It Makes Sense
As a rough guide, the S-corp election starts to make sense once a business is consistently profitable enough that the payroll-tax savings clearly exceed the added payroll, filing, and accounting costs. Many advisors point to a level of steady net profit — often somewhere in the range where an owner is earning well beyond a reasonable salary — as the point to run the numbers. The right move is to have an accountant model your specific situation: your profit, a defensible reasonable salary, and the real added costs. Electing too early is a common mistake that creates paperwork and expense without a payoff.
A Worked Example
Imagine your LLC nets $120,000 in profit. As a default LLC, roughly all of that is subject to self-employment tax. Elect S-corp treatment and you might pay yourself a reasonable salary of, say, $70,000 (subject to payroll tax) and take the remaining $50,000 as distributions (not subject to self-employment tax). The self-employment tax you avoid on that $50,000 can be several thousand dollars — but from it you subtract the cost of running payroll, filing a separate return, and extra accounting, which might run a quarter to a third of the savings. Net, a profitable business like this often comes out ahead. Run the same math on a $30,000-profit business and the added costs likely swamp the savings — which is exactly why it’s a numbers question, not a one-size answer.
Frequently Asked Questions
Is an S-corp better than an LLC?
They’re not opposites — an LLC is a legal structure, and S-corp is a tax election an LLC (or corporation) can make. For a profitable business, electing S-corp treatment can lower self-employment taxes; for a lower-profit one, the added payroll and filing costs often outweigh the savings. It depends on your numbers.
What is a “reasonable salary” for an S-corp?
It’s pay that’s reasonable for the work you actually do, comparable to what someone would earn doing your job elsewhere. The IRS requires it because the salary portion is subject to payroll tax; paying yourself an unreasonably low salary to avoid tax on distributions can trigger scrutiny and penalties.
When should I elect S-corp status?
Generally once your business is consistently profitable enough that the payroll-tax savings clearly beat the added costs of payroll, a separate tax return, and extra accounting. Have an accountant model your specific profit and a defensible reasonable salary before electing — doing it too early is a common, costly mistake.
The Bottom Line
The S-corp question is really about a tax election, not a type of company: an LLC can elect S-corp treatment to split income into a reasonable salary plus distributions, cutting self-employment tax on the distribution portion. But the election adds payroll, a separate return, and accounting costs, so it only pays off once profits are high enough for the savings to clear that overhead. Don’t elect on a hunch — have an accountant run your actual numbers, and make the move when the math, not the hype, says so.
