When an S corp election actually saves you money, and when it just adds payroll

Start with what's left after you pay yourself

Short answer: if what's left of your profit after paying yourself a fair wage is under about $25,000, an S corp election usually costs about what it returns. For many owner-operators, that's around $80,000 of profit before they pay themselves. Above $150,000 of profit it's usually real money. Those are rules of thumb, not law, and I'll show you the arithmetic so you can run your own.

Two numbers drive everything, and people mix them up. The first is your profit before you pay yourself. If you do $900,000 in revenue as a roofing company and $820,000 of it goes out the door in materials, crew, truck payments and insurance, you are an $80,000 business for this conversation. Revenue is vanity. The second number is what's left after you subtract what you'd have to pay an outsider to do your job. That second number is the only place the savings can come from.

I've owned a bakery, built escape rooms and rehabbed houses, so I've been on the owner's side of the paperwork. I'm not your CPA, though. Take this math to yours before you file anything.

Where the money actually comes from

As a sole proprietor or a single-member LLC, your business profit is hit with self-employment tax: 15.3% total, which is 12.4% Social Security plus 2.9% Medicare (IRS). The Social Security piece stops at the annual wage base. For 2026 that's $184,500 (IRS), and for 2027 it's $192,300 (Social Security Administration). It moves every January. Medicare's 2.9% never stops.

Elect S corp status and the business splits your take into two buckets. Bucket one is W-2 wages, and those get the full 15.3% payroll tax, half paid by the company and half by you. Bucket two is distributions, and distributions are not subject to Social Security or Medicare tax.

That's the whole trick. This is not an income tax play. Your federal income tax stays roughly the same either way, apart from the 199A wrinkle below. The only thing you're buying is a smaller payroll-tax base. So your savings top out around 15% of whatever you can legitimately take as a distribution instead of wages, and the word doing all the work in that sentence is "legitimately." In practice they run a bit lower, because self-employment tax only applies to 92.35% of your profit.

The same math at $80K, $150K and $250K of profit

These are hypothetical worked examples, payroll tax only, using the 2026 wage base and the statutory rates. Each dollar figure in the headings is profit before you pay yourself. I'm assuming $2,500 to $4,000 a year in added costs, which is a budgeting guess, so get real quotes. Your CPA will sand off the edges, but the shape is right.

$80,000 of profit. Say a fair salary is $55,000, which leaves $25,000. Self-employment tax would be about $11,300. Payroll tax on the salary is about $8,400. You save roughly $2,900. Subtract payroll service, a corporate return and the bookkeeping cleanup, and you're at a wash or a small loss for a meaningful pile of new hassle.

$150,000 of profit. Say salary $75,000, leaving $75,000. Self-employment tax would be about $21,200. Payroll tax on the salary is about $11,500. You save roughly $9,700. After costs, that's about six or seven grand a year. That's real money.

$250,000 of profit. Here's the part nobody mentions at the networking lunch: your reasonable salary has to climb too. Say $130,000 salary, leaving $120,000. Self-employment tax would be about $29,600, because the Social Security piece already stops at the wage base. Payroll tax on the salary is about $19,900. You save roughly $9,700, not the $18,000 the napkin math promised, and about the same as the $150,000 example. The benefit does not scale forever. It plateaus.

There's a second wrinkle at the high end: the 20% qualified business income deduction under Section 199A. Paying yourself wages lowers your pass-through profit, which can lower that deduction. Above certain income levels, W-2 wages can also help you clear a limit on it. That's a CPA question, not a napkin question.

Reasonable salary is where owners blow it, in both directions

The IRS requires that an S corp shareholder who works in the business take reasonable compensation before distributions. There is no formula in the code. The factors courts and the IRS look at are your duties, hours, training, what comparable businesses pay for the same role, and what it would cost to hire a replacement.

Owners get this wrong two ways.

• Too low. The guy who nets $200,000 and pays himself $24,000 is writing the audit adjustment himself. When the IRS recharacterizes distributions as wages, you owe the back payroll tax plus penalties and interest, and you spend a lot of your life on it. The 60/40 split you hear about is a rule of thumb somebody invented, not a safe harbor.
• Too high. The owner who panics and runs the whole profit through payroll has created an S corp that saves exactly zero American dollars and added three filings. Fear is expensive.

The honest test: what would you have to pay a competent stranger to do everything you do in this business, at market, in Northern Colorado? Write that number down. Keep the comparable job postings you used in a folder. If anybody ever asks, you have an answer in five minutes instead of five weeks.

What being an S corp actually costs you every year

Here's the line item list people skip:

• Payroll service. Even for one employee, you're registering for federal and state withholding and handling 941s, a 940, a W-2 and W-3, and state unemployment. Get a quote, because the price depends on the provider and your state registrations.
• A corporate tax return. Form 1120-S is a separate return with K-1s. Most CPAs charge more for it than for a Schedule C. Budget a meaningful increase, and ask for the number in writing before you elect.
• Real bookkeeping. Not a shoebox. The entity has to behave like an entity.
• Your time. Payroll deadlines don't move because you're on a roof or your dishwasher quit.
• State items. In Colorado that includes unemployment insurance registration and FAMLI premiums on wages, plus a pass-through entity tax election worth asking about.

Add it up honestly and add 20% for the oopsie fund. If the total cost is more than half your projected savings, you're paying a lot for a story you get to tell at lunch.

It makes your books messier before it makes them better

Year one is the ugly year. You can no longer take money whenever you feel like it. Draws become either payroll or documented distributions. The business card has to stay business. If you've been running your phone bill and your kid's hockey through the company, that stops, or it becomes a shareholder loan somebody has to track.

Two things trip up a lot of owners: health insurance premiums for a more-than-2% shareholder have to run through your W-2 to be deductible, and expense reimbursements need an accountable plan so they aren't treated as wages. Neither is hard. Both are easy to forget until March.

The flip side, and this is why I still like the election when the math works: it forces separation. Clean books are an asset, not a liability. Three years of 1120-S returns with a real salary line and clean distributions is a business a buyer or a banker can read. A Schedule C with personal gas and groceries in it is a mess somebody has to untangle, and they'll discount your price for the trouble.

What it does to a loan application or a sale

If you're going to apply for an SBA 7(a) loan or a commercial mortgage in the next two years, talk to the lender before you elect. Underwriters look at your personal income too. An owner who shrinks his W-2 to $38,000 to save payroll tax just told the mortgage desk he makes $38,000. Distributions and K-1 income often need two years of history before a lender will count them. A few thousand in payroll tax savings isn't worth missing the loan.

On the sale side, a buyer values your business on seller's discretionary earnings, which means they add your salary back anyway. The structure matters less than the cleanliness. But one real thing: if you ever sell the business itself, an S corp can change whether the deal is an asset sale or a stock sale and what the tax bill looks like, including built-in gains rules if you converted from a C corp. That's a conversation to have before the election, not during a letter of intent.

I sold my bakery with seller financing, which puts the seller in the lender's seat. Whoever is carrying the risk wants the numbers on the returns to match the numbers in the room. That's about consistency more than structure.

Deadlines, late elections, and the 15-minute CPA conversation

Form 2553 is the election. For an existing business on a calendar year, it's generally due by March 15 to be effective for that year. A brand-new entity generally gets two months and 15 days from the start of its first tax year. Miss it and you're not necessarily cooked: the IRS offers late election relief under Rev. Proc. 2013-30, generally within 3 years and 75 days of the intended effective date, if you had reasonable cause and you've otherwise been acting like an S corp. Your CPA can tell you whether you qualify.

Now, how do you eat this elephant? One bite. Pull last year's return, find net profit, subtract what you'd pay a stranger to do your job, and multiply what's left by 15%. That's your ceiling before costs. Then bring these to your CPA and the meeting takes fifteen minutes:

1. What do you think my reasonable salary should be, and what are you basing it on?
2. What's your fee for the 1120-S versus my Schedule C, all in?
3. What happens to my 199A deduction at that salary?
4. Does the Colorado pass-through entity election help me?
5. Am I applying for financing in the next 24 months, and does this hurt it?
6. If we elect, who's running payroll in January, and what's the calendar?

If the net is under a couple thousand dollars a year, skip it and revisit when profit grows. That's not failing the test. That's passing it. If you want a second set of eyes on the whole picture before you file anything, the free Business Checkup is a good first stop to see whether this is even your biggest problem.
