What Is
An S-Corp,
Really?

An S-Corp isn't a type of business. It's a tax election you file with the IRS, usually on top of an LLC or a corporation you already formed. Nothing about how you operate changes. What changes is how the tax code treats the money you take out of the business, and how much of it gets hit with self-employment tax.

That distinction matters because most of the confusion around S-Corps comes from people treating it like a status symbol, something you graduate into once your business is "real enough." It's not that. It's a mechanical tax decision with a breakeven point, and below that point, it actively costs you money.

What the election actually does

If you're self-employed (a sole proprietor or a single-member LLC taxed the default way), every dollar of profit your business makes is subject to self-employment tax. That's 15.3% on top of your regular income tax, covering both the employer and employee halves of Social Security and Medicare. There's no way around it inside that structure. Profit is profit, and the tax code treats all of it as earnings from your labor.

An S election changes the shape of that income. Once you make the S election, the tax rules require you to pay yourself a reasonable salary through payroll for the work you actually do in the business. That salary is subject to payroll taxes, same as any employee's paycheck. But anything left over (the profit beyond your salary) gets paid out to you as a distribution, and distributions are not subject to self-employment tax. To be clear, distributions still get hit with regular income tax, since the profit passes through to your return either way. What they skip is the 15.3%.

That's the entire mechanism. Split income into salary and distribution. Salary pays payroll tax. Distribution doesn't. The savings come entirely from the gap between what you'd have paid in self-employment tax on the full amount versus what you pay in payroll tax on just the salary portion.

That gap, the payroll tax you avoid on the distribution portion, is the entire benefit. It's real money. It's also the only thing the election does. It doesn't lower your income tax rate, it doesn't create new deductions, and it doesn't shield you from liability any differently than your LLC already does.

The breakeven logic, explained in plain terms

The reason we won't just hand you a number and call it a day is that the breakeven point depends entirely on your situation, but the logic behind it is simple enough to walk through.

Running an S-Corp costs money no matter what: payroll processing, a separate business tax return, usually more involved bookkeeping. Call that your fixed overhead. It typically runs somewhere in the range of a couple thousand dollars a year once you account for payroll software and the additional filing.

The tax savings, on the other hand, scale with your profit. The more distribution income you can shift out of self-employment tax, the bigger the savings, but you can't shift all of it, because the IRS expects you to pay yourself a real, defensible salary first. On a small profit, almost all of it has to go toward a reasonable salary anyway, leaving little room for distributions that skip self-employment tax. There's nothing left to actually save on, but you're still paying the overhead.

As profit grows, the salary portion stays roughly tied to what the work is worth, while the distribution portion grows. That's where the savings start to outpace the overhead. Where exactly that crossover lands is different for every business, because it depends on your profit level, what a defensible salary looks like for your work, your state's costs, and your filing overhead. There is no universal breakeven number, and anyone who hands you one without running your numbers is guessing. One more wrinkle: since 2018, the QBI deduction has narrowed the S corporation's edge for many owners, because the salary you pay yourself is not eligible for that deduction while pass-through profit generally is. The self-employment tax savings are still real, but the net benefit is smaller than the older rules of thumb suggest.

If you can't answer all three with confidence, you're not ready to make the election yet, even if your business is comfortably profitable.

Who actually benefits

The S election tends to make sense for profitable, self-employed business owners and LLC members whose income comes primarily from their own labor and who've cleared their own breakeven point consistently, not just in one good year. Think consultants, contractors, agency owners, and service providers who've moved past the early, lean stage of the business.

It tends to make less sense for businesses that are capital-intensive rather than labor-intensive, where most of the profit comes from assets or inventory rather than the owner's personal work. It also makes less sense for anyone whose income swings wildly year to year, since payroll is a commitment you have to keep up even in a slow quarter.

What people skip when they get excited about the savings

The tax savings get all the attention. The tradeoffs get glossed over, and they're real.

None of these tradeoffs are reasons to avoid the election if your numbers support it. They're reasons to make the decision with real numbers instead of a rule of thumb you heard from another business owner whose situation might look nothing like yours.

How we actually make the call

Before we ever recommend the election, we run your actual profit, your actual reasonable salary range, and your actual overhead costs through the math, not a generic rule of thumb. If the numbers clear the bar, we help you set up payroll correctly and file the election on time. If they don't, we tell you that too, and we revisit it as your numbers change.

The S election is a tool, not a milestone. The goal isn't to elect it as early as possible; it's to elect it exactly when it starts paying for itself, and not a year before.
