“My CPA says I should switch to an S-Corporation — is it really worth it?”
This is one of the most common questions owners ask when preparing 2025 U.S. tax returns (filed in 2026).
The short answer: S-Corp status can reduce employment taxes, but your QBI deduction and compliance costs can change the math — so the best choice depends on your real numbers.

1️⃣ What Is an S-Corporation for U.S. Tax Purposes?
First important point: an S-Corporation (S-Corp) is not a special type of corporation formed at the state level.
It is a tax status under Subchapter S of the Internal Revenue Code.
Legally, you form a corporation (or an LLC), and then you elect S-Corp treatment for federal tax purposes by filing Form 2553.
In most cases, an S-Corp does not pay federal corporate income tax the way a C-Corporation does.
Instead, the company files Form 1120-S and passes income, deductions, credits, and other items through to shareholders via Schedule K-1.
2️⃣ How S-Corps Are Taxed (Big Picture)
- The S-Corp files Form 1120-S each year.
- The company issues Schedule K-1 to each shareholder.
- Shareholders report those items on their individual Form 1040, even if the business does not distribute cash.
The crucial twist is employment taxes:
- Owners who actively work in the business generally must be paid a reasonable W-2 salary.
- That salary is subject to FICA (Social Security & Medicare), just like any employee.
- Distributions on top of salary are generally not subject to SE tax / FICA when structured correctly.
3️⃣ S-Corp vs LLC vs C-Corp — One-Table Comparison
| Category | Schedule C / Default LLC | S-Corporation | C-Corporation |
|---|---|---|---|
| Income tax layer | Pass-through | Pass-through | Corporate level + dividends (often double tax) |
| Employment tax | SE tax on most net profit | FICA on W-2 wages only (not on distributions) | FICA on wages; dividends are not wages |
| QBI deduction | Based on QBI (generally net business income) | W-2 wages are NOT QBI; QBI is generally the pass-through business income after wages | Not a QBI entity (in most cases) |
| Complexity / admin | Lower | Higher (payroll + 1120-S + compliance) | Higher (corporate filings + possible double tax planning) |
| Owner eligibility rules | Flexible | Strict (100 shareholders max, one class of stock, eligible shareholders only) | More flexible for investors |
An S-Corp decision is never “FICA savings only.” The correct analysis is:
(employment tax change) + (QBI deduction change) − (added compliance & payroll cost).
4️⃣ Where the Real FICA Savings Come From
The headline benefit people chase with S-Corps is “FICA savings.” Here’s a simplified example:
Scenario A: Schedule C / Default LLC
• Net business profit: $120,000
• Subject to self-employment tax (15.3%) on most of that amount
→ SE tax roughly: about $18,000 (rounded)
Scenario B: S-Corporation
• Reasonable salary to owner: $70,000 (W-2 wages)
• Remaining profit as distributions: $50,000
• FICA on $70,000 ≈ $10,700 (rounded)
• Distributions of $50,000: generally no FICA / SE tax
▶ Approximate employment tax savings: $18,000 − $10,700 ≈ $7,300/year
*Numbers are rounded for illustration. Actual results vary by wage base, Additional Medicare Tax, and your total tax picture.
Employment tax savings is not the final answer. Estimate your net benefit like this:
Net benefit ≈ FICA/SE savings − (payroll service + payroll filings + FUTA/SUTA impacts + 1120-S prep fee + bookkeeping)
If your “net benefit” is small or inconsistent, staying Schedule C may be the smarter (and safer) choice.
5️⃣ Important Twist: QBI Deduction Can Change After an S-Corp Election
Here’s the nuance many owners miss: the QBI deduction (Qualified Business Income deduction) may change when you move to an S-Corp structure.
In general terms:
- W-2 wages paid to you as the owner-employee are not QBI.
- Your potential QBI amount is typically tied to the pass-through business income (often the profit remaining after wages and other business expenses).
- Depending on your income level and business type, QBI rules can also interact with wage/property limitations (and special service business limits).
An S-Corp can lower employment taxes, but if your wages are set high, your QBI amount may shrink. The “best” structure is the one that wins after you model both employment taxes and the QBI effect together.
6️⃣ Missed the Timing? Late S-Corp Election Relief (Quick Note)
Since this post is being read heavily in January, here’s a real-world issue:
some owners realize “S-Corp was the plan” only after the year has already started.
In certain cases, the IRS may allow a late S-Corp election when you meet the eligibility rules, intended the election, and can show reasonable cause for filing late.
Late-election relief is not automatic. If you think you missed the window, don’t guess — document your facts, confirm eligibility, and consider professional guidance before filing payroll and the first S-Corp return.
7️⃣ When an S-Corporation May Not Be a Good Fit
- Very low or unstable profits: Savings may not cover added payroll + compliance cost.
- High state-level fees/taxes: Some states impose minimum taxes or special entity fees.
- Investor/ownership constraints: S-Corps have strict shareholder and one-class-of-stock rules.
- Audit sensitivity: Too-low wages can trigger reclassification and payroll tax assessments.
8️⃣ Practical FAQs from Small-Business Owners
A1. Often, yes. A domestic LLC can elect S-Corp tax treatment by filing Form 2553 (and sometimes an entity classification election first).
You must still meet all S-Corp eligibility rules and file correctly.
A2. Not always. It usually makes sense only when profits remain meaningful after paying a reasonable salary and covering payroll/compliance costs.
A3. Distributions are generally not subject to FICA, but you are still taxed on your share of S-Corp income.
Also, distributions above your stock basis can become taxable capital gain.
A4. No. This is one of the most common audit triggers. If there is no reasonable compensation,
the IRS can reclassify distributions as wages and assess payroll tax, penalties, and interest.
A5. There is no universal “60/40 rule.” In practice, the IRS looks at job duties, hours worked, and market-rate pay for similar roles.
The safer approach is to support your salary with real-world facts and documentation.
9️⃣ Google Q&A (Quick Answers)
-
Does S-Corp status reduce my total taxes automatically?
Not automatically. It can reduce employment taxes, but your QBI deduction and extra compliance costs can change the result. -
What’s the biggest S-Corp audit risk for owners?
The #1 risk is paying an unreasonably low salary while taking large distributions. The IRS can reclassify distributions as wages. -
How much profit do I need before an S-Corp usually makes sense?
Many owners start exploring it when profits are consistently strong after a realistic salary — but the correct threshold depends on your payroll costs, state rules, and QBI impact.
