BlogIf you own the company you work for, nobody hands you a pay structure — 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 — 10% through 37% in 2025 — 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 — 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.
The constraint is the IRS reasonable compensation standard. Your salary must reflect the work you actually do, judged against what a comparable employee in your industry, market and role would earn. Owners who pay themselves a token $20,000 and take $250,000 in distributions are a well-known audit target, and recharacterisation brings back payroll tax, interest and penalties. Document your reasoning: comparable salary data, hours worked, duties performed.
What salary buys you
Wages are not just a tax cost. They generate the earnings record that determines your future Social Security benefit. They create the compensation base you need to fund a Solo 401(k) or SEP-IRA, which for many owners is the single largest tax-deferral opportunity available. They also make mortgage underwriting dramatically easier, because lenders can read a pay stub far more comfortably than a K-1 and a distribution history.
There is also the qualified business income deduction to consider. For pass-through owners, section 199A can shelter up to 20% of qualified business income, and for higher earners the deduction is limited by W-2 wages paid — which means cutting your salary to the bone can actually cost you deduction capacity.
Don't forget your state
The calculator models federal tax only, and that is a real limitation. A California owner faces personal rates above 13% and an S corporation franchise tax; a Texas or Florida owner faces neither. Some states tax dividends differently from wages. Before you settle on a structure, add your state's corporate, franchise and personal income tax to both columns and see whether the ranking survives.
How to decide
Run the numbers at your actual income level, not at a round number. Crossing the Social Security wage base, the $200,000 Additional Medicare and NIIT thresholds, or a qualified dividend bracket can flip the answer entirely. Then check your entity election, your retirement plan goals and your borrowing plans for the next few years. Finally, revisit the decision annually: thresholds are indexed and your profit will move.
