Social media made the S-Corp sound like a cheat code.
Set one up, slash your taxes, done.
But that's not how it works — and a lot of business owners are finding that out the hard way.
The entity structure isn't the win.
What you do inside the structure is.
And most S-Corp owners — even the ones pulling $750k+ in profit — are getting it wrong in ways that cost them tens of thousands every year.
TL;DR
The move: Use your S-Corp structure to maximize retirement contributions, QBID, and accountable plan reimbursements — not just reduce SE taxes.
The risk: A low or zero salary with a SEP-IRA caps your retirement contributions around $25k and may eliminate your QBID entirely.
The upside: With the right salary, plan design, and a Solo 401(k), you can shelter up to $72k per year in tax-deferred or tax-free dollars.
The Strategy
Here's what an S-Corp actually does well.
It lets you split your business income between a W-2 salary and distributions — and only the salary portion gets hit with the 15.3% self-employment tax.
At $200k+ in profit, that savings becomes real.
At $500k+, not having this structure can be very expensive.
But here's where most people stop thinking.
They get the S-Corp, set a low salary to minimize SE taxes, open a SEP-IRA, and call it a day.
The problem: a SEP-IRA caps contributions at 25% of W-2 compensation.
At a $100k salary, that's roughly $25k in deductions.
That's it.
Meanwhile, business owners at $750k–$1M in profit are paying taxes on hundreds of thousands of dollars that could have been sheltered with the right plan design.
And there's another layer most people miss entirely — QBID.
For non-SSTB businesses above $500k in profit, failing to structure your S-Corp correctly can wipe out your Qualified Business Income Deduction completely.
That's a 20% deduction on qualified income.
Gone.
We regularly see clients come in at the $500k+ level getting $0 in QBID because they never made the switch.
The Playbook
Step 1: Run the actual numbers before assuming an S-Corp makes sense.
Under $100k in profit, the payroll costs, compliance, and accounting fees often outweigh the savings.
$100k–$200k is where it becomes a real conversation.
$200k+ is where it usually pays off — but only with the right moves inside the structure.
Step 2: Set a reasonable salary that's actually defensible — and optimized.
The IRS requires a "reasonable compensation" figure.
But reasonable doesn't mean minimal.
Your salary also determines how much you can contribute to your retirement plan, so there's a strategic middle ground that needs to be modeled, not guessed.
Step 3: Replace your SEP-IRA with a Solo 401(k) — or something more powerful.
With a Solo 401(k) at a $100k salary, you can contribute:
$23,500 employee deferral
~$25,000 employer contribution (25% of W-2)
Up to $72,500 total with a Mega Backdoor Roth design (which a SEP-IRA doesn't allow)
That's nearly triple what most S-Corp owners are currently sheltering.
Step 4: Set up an accountable plan.
If your S-Corp is reimbursing you for home office, phone, internet, or vehicle expenses — it needs to be done through a formal accountable plan.
Done correctly, those reimbursements are tax-free to you and deductible to the business.
Done incorrectly, or not at all, that's free money left on the table every year.
Step 5: Bring in the right people.
This isn't a set-it-and-forget-it structure.
You need a CPA who does proactive planning — not just return filing — and ideally someone who can coordinate your entity structure, salary, retirement plan, and state tax strategy together.
