If you own the company you work for, nobody hands you a pay structure β you design it. And the design matters: the same profit can leave your business as W-2 wages or as a dividend, and the difference in what you keep can run into five figures. Here is how to think about it under 2025 federal rules.

Two routes, two tax systems
Salary is a deductible business expense. It reduces the company's taxable profit, but it carries payroll tax on both sides: 6.2% Social Security up to the $176,100 wage base for 2025, plus 1.45% Medicare with no cap, matched dollar for dollar by the employer. Wages above $200,000 for a single filer pick up an extra 0.9% Additional Medicare Tax that the employer does not match. On top of that, wages are taxed at ordinary rates β 10% through 37% in 2025 β after the $15,000 standard deduction.
Dividends from a C corporation take the other path. Profits are taxed once at the flat 21% federal corporate rate, and the distribution is then taxed to you at qualified dividend rates of 0%, 15% or 20%, plus the 3.8% net investment income tax above $200,000 of modified AGI. No payroll tax at all β but the profit has effectively been taxed twice.
A concrete example
Suppose you want $120,000 of gross income. Paid as S corporation salary, your company spends roughly $129,000 including its half of FICA. You lose about $9,180 in employee payroll tax and around $18,400 in federal income tax, so roughly $92,400 reaches your bank account. Paid as a C corporation dividend, distributing $120,000 requires about $151,900 of pre-tax profit. After roughly $15,700 of qualified dividend tax, you keep about $104,300.
The dividend wins on take-home, but it consumes almost $23,000 more of company profit and generates zero Social Security credit. That trade-off is the whole debate in one line.
Why most owners use an S corporation
The S corporation exists precisely to split the difference. You pay yourself a reasonable salary, subject to payroll tax, and take the remaining profit as a distribution that is not subject to payroll tax and is not taxed again at the entity level. That structure captures most of the payroll-tax saving without the double taxation of a C corp.
