Once your restaurant clears about $60,000 in net profit, you are probably handing the IRS $8,000 to $15,000 a year you do not have to. The reason is the 15.3 percent self-employment tax, and a single tax election can shut most of it off. The catch is that the election only pays once your profit is big enough to cover the cost of running it, and most articles never tell you where that line is. This one leads with it.

First, clear up the question itself. "LLC vs S corp" sounds like a fork in the road where you pick one entity or the other. It is not. For almost every restaurant owner reading this, the LLC stays exactly where it is. S corp is a tax election you layer on top of the LLC by filing one form with the IRS. You do not dissolve anything, you do not get a new bank account, and your liability protection does not change. You change how the profit is taxed, nothing else.

The only number that decides this: your net profit

Here is why the election matters. A single-member LLC is a disregarded entity to the IRS, which is a formal way of saying it is taxed like a sole proprietorship. Every dollar of net profit gets hit with self-employment tax: 15.3 percent, split as 12.4 percent for Social Security and 2.9 percent for Medicare. That is on top of regular income tax. The Social Security piece stops at the 2026 wage base of $184,500, but Medicare never stops.

Run a restaurant that nets $120,000 and you are paying self-employment tax on all $120,000. There is one softener built into the sole-proprietor rules: you deduct half of your self-employment tax above the line, and the tax is figured on about 92.35 percent of net profit rather than the full amount. That trims the bite, but it does not close the gap. The S corp closes it.

An S corp changes the math by splitting your profit into two buckets: a reasonable salary that runs through payroll and carries the full FICA tax, and a distribution that does not. The distribution skips the 15.3 percent entirely. That gap is the whole game. A multi-member LLC works the same way, except it defaults to partnership tax treatment instead of sole proprietorship, and the election still rides on top of the same LLC.

The salary math at three profit levels

Talk is cheap, so here is the math at three real profit levels. The pattern is simple: the bigger your profit, the bigger the slice you can move out of payroll and away from self-employment tax. The reasonable salary numbers below are illustrative; yours depends on your role, which we cover in a minute.

At $60,000 the savings are real but thin. Move $15,000 to a distribution and you skip roughly $2,300 in self-employment tax. That sounds great until you subtract the cost of running the S corp, which we get to next. At $120,000 the picture changes hard: roughly $9,180 saved, and the compliance cost barely dents it. At $200,000 a chunk of your distribution sits above the $184,500 Social Security wage base, so the Social Security portion is already maxed out on the salary side, but the 2.9 percent Medicare savings plus the Social Security savings on the salary-to-base spread still push total savings into the $12,000 to $15,000 range. Frame all of these as estimates, because your exact number depends on your salary, your state, and your other income.

The compliance drag, and when this is a bad idea

No honest version of this article skips the costs. An S corp is not free, and the costs are why the election is a mistake for a lot of small operators.

Once you elect, three things become non-optional. You must run payroll, which means a payroll service at roughly $40 to $150 a month. You must file a separate business tax return, Form 1120-S, every year regardless of how the year went, which runs about $1,200 to $2,500 on top of your personal return. And you must pay yourself a reasonable salary, which the IRS audits.

Add it up and the floor cost of running an S corp lands somewhere around $2,000 to $3,500 a year. Now go back to the $60,000 owner saving $2,300. The election barely breaks even, and a slow year could put it underwater. That is why the common practitioner trigger sits at about $50,000 to $60,000 in net profit. Below it, stay a plain LLC and keep your life simple.

There is a second cost that does not show up on an invoice: your time and attention. Payroll has to run on schedule, the salary has to be defensible, and the second return has to be filed even in a year you would rather forget the business existed. If you are a single-location operator already stretched thin, that operational drag is real. The election rewards owners whose profit is both large enough and steady enough to justify the discipline. A restaurant that swings from $90,000 one year to $30,000 the next is a worse candidate than one parked reliably at $70,000, even though the first one looks bigger on a good year.

What "reasonable salary" actually means for an operator

This is where owners get into trouble. Reasonable salary does not mean the smallest number you can get away with. The IRS rule is that an S corp must pay a shareholder-employee reasonable compensation for the work they do before taking distributions. If you pay yourself $20,000 and pull $100,000 in distributions while working sixty hours a week running the floor, you have painted a target on your return.

The test is simple to state: what would you pay someone else to do your job? If a general manager running your operation would earn $65,000, your salary should be in that neighborhood, not a fraction of it. When the IRS reclassifies a too-low salary, it does not just collect the back payroll tax at 15.3 percent. It adds penalties and interest. The savings you chased turn into a bill.

Signs you have outgrown the plain LLC

• Your net profit clears about $60,000 and is steady year over year
• You already pull money out of the business as owner draws
• You can comfortably pay yourself a real, market-rate salary and still have profit left to distribute
• You are willing to run payroll and file a second tax return
• You want a repeatable, defensible structure, not a year-end scramble

The QBI wrinkle most owners miss

Here is the trap that turns "minimize my salary" into a bad strategy. The 20 percent qualified business income deduction, made permanent by the One Big Beautiful Bill Act, lets you deduct up to 20 percent of your business income. But your W-2 salary is excluded from qualified business income. Only the distribution side counts.

So every dollar you move from distribution to salary cuts your self-employment tax savings, and every dollar you keep as distribution shrinks the salary that the IRS will accept as reasonable. The salary is a balance point between two competing benefits, not a number to drive to zero. This is exactly the kind of calculation worth running with a professional before you set your payroll, because getting it wrong costs you on both sides.

How to actually make the switch

If your numbers say yes, the mechanics are not complicated.

1. 1
   Set up or confirm your LLC

   The S corp election rides on top of an LLC. If you do not have one yet, form it first. A formation and registered-agent service such as Northwest Registered Agent handles the state filing and keeps your home address off the public record.
2. 2
   File Form 2553

   Elect S corp tax treatment with the IRS. The general window is two months and fifteen days from the start of the tax year you want it to apply to. Miss it and there is late-election relief if you have reasonable cause, but do not plan around that.
3. 3
   Set up payroll

   Run yourself through a payroll service at your reasonable salary. This is the step that makes the whole structure defensible.
4. 4
   Pay the salary, distribute the rest

   Run your first reasonable paycheck with the right FICA and withholding, then take the remaining profit as distributions through the year.
5. 5
   File Form 1120-S every year

   The S corp return is separate from your 1040, due March 15, and it flows your income to your personal return on a K-1.

One more practical note. If you own more than one location, do not assume one S corp covers everything or that every entity should elect. Multi-entity owners often hold each restaurant in its own LLC for liability reasons, and the election decision gets made entity by entity based on each one's profit. The threshold logic does not change; it just applies more than once.

The entity election is one of several money levers an operator controls, and it is not even the biggest one for most restaurants. If you employ tipped staff, the FICA tip credit and a Section 125 plan often move more money than the S corp election does, and they stack on top of it. An owner who elects S corp, claims the tip credit on reported tips, and runs a Section 125 plan that genuinely saves on payroll tax is pulling three separate savings levers from the same payroll. The point is to pull every lever your numbers justify, in the right order, instead of fixating on one and ignoring the rest.
