Same $5,000, Different Tax Structures
1️⃣ Introduction: Same Owner, Different Tax Rules
When I consult with S-Corp and C-Corp owners, the most common questions I hear are:
“If I take a $5,000 salary, how much does it actually cost the company?”
“If I take $10,000 as a dividend, how much tax will I owe?”
Even though the amounts are the same, the tax structure and cash flow impact are very different. Understanding these differences is the first step to an efficient cash distribution strategy.
2️⃣ Payroll Tax Perspective: FICA Exemption
Payroll taxes like FICA (Social Security & Medicare), FUTA/SUTA, and Workers’ Comp apply to salaries for both S-Corp and C-Corp owners.
Owners pay 7.65% as employees, and the company pays 7.65% as the employer.
The main difference comes in how income beyond salary is treated:
-
S-Corp: Profits distributed as Distributions → FICA exempt → payroll tax savings
-
C-Corp: Profits distributed as Dividends → FICA exempt, but Dividend Tax applies → limited payroll tax savings
I often see C-Corp owners surprised when they calculate dividend taxes. This is where confusion usually happens.
3️⃣ Key Difference in Dividend/Distribution Treatment
-
Commonality: Neither distributions nor dividends are deductible for the company → corporate taxable income is not reduced.
-
FICA Exemption: Both S-Corp distributions and C-Corp dividends are not considered earned income → no FICA.
-
Income Tax Difference:
-
S-Corp: distributions are already passed-through → no additional personal tax
-
C-Corp: dividends come from after-tax corporate profits → Qualified Dividend Tax (0–20%) applies
-
In practice, many S-Corp owners forget this and only focus on payroll, ending up surprised by actual cash outflow.
C-Corp owners, on the other hand, often underestimate dividend tax, leading to unexpected total tax bills.
4️⃣ Cash Flow Example
Assume a $5,000 salary plus $10,000 cash withdrawal:
| Item | S-Corp | C-Corp |
|---|---|---|
| Salary | $5,000 → Payroll tax included: $5,512.50 | $5,000 → Payroll tax included: $5,512.50 |
| Extra Cash | $10,000 distribution → FICA & additional tax exempt | $10,000 dividend → Qualified Dividend Tax 15% → $1,500 tax |
| Net Received by Owner | $15,000 | $13,500 |
| Total Tax Paid | Only payroll & income tax on salary | Payroll + dividend tax included |
Many C-Corp owners are surprised by the extra dividend tax when planning withdrawals.
5️⃣ Key Takeaways
| Point | S-Corp | C-Corp |
|---|---|---|
| FICA Tax | Salary only | Salary only |
| Distribution/Dividend | FICA exempt, no extra tax | FICA exempt, Dividend Tax applies |
| Deductible Expense | No | No |
| Strategy | Salary + Distribution → maximize payroll tax savings | Salary + Dividend Tax → manage total tax liability |
Bottom line: C-Corp owners must plan cash withdrawals considering corporate tax, payroll tax, and dividend tax together.
S-Corp owners can maximize tax efficiency by leveraging distributions to reduce payroll taxes.
