A lot of owners are leaving money on the table by not electing S-Corp at the right time. Others jump in too early, elect S when the administrative and compliance costs eat up everything they saved, and end up paying more than they would have as an LLC.
S-Corps are most famous for saving self-employment taxes. The timing matters, though. And there are quite a few pitfalls along the way.
The Self-Employment Tax Problem
So if you're a sole prop, a single member LLC, or a partnership where you're a general partner, 100% of your profits get hit with self-employment tax. Social Security at 12.4%. Medicare at 2.9%. On $100,000 in profit, you're paying $15,300 in self-employment tax alone, and then you have income tax on top of it.
It gets expensive fast.
On $200,000 in profit you're looking at roughly $30,600, though the Social Security wage base does cap at $176,100 for 2025. So the 12.4% ends there. The 2.9% Medicare goes on to infinity.
How the S-Corp Saves Tax
With an S-Corp election, you become a shareholder in your business and also an employee. You pay yourself a reasonable salary, and then the rest of the profits are counted as distributions. Only the salary is subject to payroll taxes. Distributions are not.
Example:
- $170,000 in business profit
- $90,000 reasonable salary (subject to 15.3% payroll tax)
- $80,000 distribution (not subject to payroll tax)
- Savings: $80,000 x 15.3% = $12,240
The bigger the gap between salary and profits, the more money you save. But you have to pay reasonable comp. It is one of the most abused issues when it comes to S-Corps, and I'll get into why in a minute.
Why the $50,000 Threshold Advice Is Wrong
A lot of times you'll hear CPAs give the advice that once profit exceeds $50,000, make the switch. I don't agree with this. Below $40,000 in profit, the savings rarely justify the extra complexity. Fine. But the $50,000 number assumes you're paying yourself $50,000, and there are very few professions where you're going to make an argument to the IRS that $50,000 is reasonable compensation for a full-time employee with ownership or management responsibility. That is especially true if your services are 100% of the revenue of the business.
I don't think a universal threshold works here. It needs to be looked at on an individual, case by case basis, because the gap in reasonable compensation between industries is enormous. A solo IT consultant billing $250,000 has a completely different salary benchmark than a freelance designer earning $75,000.
Work through the numbers for your specific situation. Factor in industry, role, revenue mix, and the real cost of maintaining an S-Corp. Then make the call.
The Hidden Costs
So here's where people get surprised.
Processing payroll, even with the most affordable providers, you're still looking at $600 to $700 a year. Additional bookkeeping, unless you do it yourself, runs in excess of $1,200 a year for a low volume entity. And the tax prep fees for an 1120S return are going to be north of $1,000.
Your administrative fees for an S-Corp are at a minimum $2,500 to $3,000 a year. Unless you want to do the work yourself. You need to factor this into your tax savings because it's often a hidden cost people don't think about when they're reading articles about how everyone needs an S-Corp.
I see this every year in our practice. An owner reads a blog post, makes the election, and then gets the bill for $3,000 in compliance fees nobody told them about.
The Reasonable Salary Trap
The IRS watches S-Corp owners who try to lowball their salary to maximize their low tax distributions. Paying yourself a $20,000 salary and taking $80,000 in distributions is a big red flag. If the IRS reclassifies your distributions as wages, the penalties they assess on top of it get expensive in a hurry.
Here's what happens when the IRS reclassifies:
The reclassified amount gets hit with the full 15.3% in FICA taxes. The company owes the employer's half at 7.65%, and since it never withheld the employee's half, the company gets stuck paying both sides. So right off the bat you're looking at 15.3% in back taxes on every dollar the IRS reclassifies.
Then the penalties start stacking. Under IRC Section 6651, the penalty for unfiled Form 941 quarterly payroll returns runs 5% per month of the unpaid tax. Caps at 25%, but it gets there fast. IRC Section 6656 tacks on failure to deposit penalties ranging from 2% all the way up to 15% depending on how late the deposits are. And IRC Section 6662 adds a 20% accuracy penalty on any underpayment due to negligence.
Interest compounds daily at the federal short-term rate plus three percentage points. It doesn't stop until everything is paid.
Then there's IRC Section 6672. The Trust Fund Recovery Penalty. This one is a 100% penalty assessed against the shareholder personally for the employee's share of FICA and withholding that should have been collected. Read that again. Personally. Not against the company. Against you. The IRS looks at two things: were you a "responsible person" (you're the sole shareholder and officer, so yes), and was the failure "willful" (you chose to pay yourself distributions instead of running payroll, so yes). I had a client come to me after the fact on one of these. What started as a $15,000 payroll tax problem turned into over $40,000 in personal liability once the TFRP and all the other penalties stacked up.
The courts have gone after S-Corp owners on this over and over. In Watson v. United States (2012), a CPA, a CPA of all people, paid himself $24,000 on income north of $200,000. Court didn't hesitate. In Radtke v. United States (1990), an owner took every dollar as dividends. Zero salary. The court reclassified every cent as wages.
So pay yourself what the market would pay someone doing your job. Pull up BLS data, look at salary surveys and job postings in your area. And document it. If the IRS comes asking, you need to be able to show your work.
Filing the Election
File IRS Form 2553. It typically needs to be filed within 75 days of formation or by March 15 for the election to apply to the full tax year. For late elections, the IRS has a pretty generous relief policy with reasonable cause. You file the form with an explanation of why you're late. They approve these routinely.
People confuse this constantly. Your LLC stays an LLC under Ohio law (or whatever state you're in). The 2553 only changes your federal tax classification. Your operating agreement, your EIN, your state registration, none of it changes.
When Not to Elect S
So I had a client a few years ago, a real estate investor, who came in after electing S-Corp on the advice of a friend. The problem: he owned three rental properties inside the S-Corp, all appreciated, and when he wanted to pull one out to do a 1031 exchange, the distribution triggered a taxable gain on the difference between his basis and fair market value. In a partnership or LLC, no taxable event. He would have walked away clean. Instead he owed over $60,000 in taxes on a property he didn't even sell.
Real estate and S-Corps don't mix. Period.
Investor situations are another one. S-Corps restrict you to one class of stock, 100 shareholders max, domestic owners only. No foreign investors. So when you're sitting across from somebody who wants preferred returns or a different economic split, you don't have the tools to make the deal work. I've watched owners lose funding because their entity structure couldn't accommodate the terms.
And if your income bounces around year to year, the fixed salary creates problems. You set your salary at $90,000 based on a $200,000 year, and then revenue falls to $120,000. You still owe payroll taxes on the $90,000. Quarterly 941 deposits don't care about your cash flow.
Watch your state too. California hits S-Corps with a minimum $800 franchise tax plus 1.5% on net income. Ohio is friendlier on this front, but every state is different and you need to know before you file.
One year of projections tells you almost nothing. Run both scenarios out three to five years.
The Partner S-Corp Setup
So one arrangement I think is underused, especially with multi-owner professional firms, is where each partner forms their own S-Corp and those S-Corps become the partners in the main partnership.
Why does this work? The partnership gives you all the flexibility: special allocations, multiple income classes, no cap on owners, foreign partners if you want them. And each individual S-Corp gives the partner inside it the self-employment tax savings from the salary and distribution split. Best of both worlds.
We set one of these up for a three partner consulting firm last year. Each partner was earning between $300,000 and $450,000 through the partnership. By routing the income through their individual S-Corps, we saved the group roughly $85,000 in combined self-employment taxes in the first year alone. Pretty significant.
Now, the compliance overhead is real. You've got the partnership return, plus an 1120S for each partner's entity, plus W-2s, plus the guaranteed payment analysis on the partnership side. The partnership agreement needs specific language around distributions, and each S-Corp has to maintain reasonable comp standards independently. If you mess up any one of those pieces, the IRS has an opening.
This is not something you put together from YouTube. You need a CPA or tax attorney who has structured these before and knows where the landmines are.
What It Comes Down To
We've saved clients six figures with the S-Corp election over the years. For the right business, the math is obvious and the savings are real.
But I've also cleaned up messes where somebody elected too early, set their salary at $30,000 on $200,000 in revenue, or shoved rental properties into an S-Corp because a friend told them to. Those conversations are never fun.
If somebody is telling you there's one magic income number where everyone needs to elect S, they're selling you something. Have your CPA run both scenarios with your actual numbers before you file the 2553.
