An entity comparison should start with how the owner plans to use the profits. Cash retained for operations, cash paid as reasonable compensation and cash distributed as dividends have different consequences. Do not compare a corporate tax rate directly with a shareholder's top personal rate and call the difference savings. Include state tax, payroll costs, benefit treatment and the timing of distributions in the same model.
Use explicit assumptions for the second layer
A C corporation generally pays its own income tax, and taxable dividends can create shareholder-level tax when profits are distributed. Compensation requires a separate deductibility and payroll analysis. Distribution treatment depends on earnings and profits and other rules, not simply the bank transfer label. A useful projection identifies which cash is retained, which is paid for services and which is distributed to shareholders.
Worked planning example
For arithmetic only, assume $100,000 of taxable corporate profit, a 21 percent federal corporate tax and distribution of all $79,000 remaining cash. If an assumed 20 percent shareholder tax applies to that entire dividend, that layer is $15,800 and combined tax is $36,800. The assumed dividend rate is not a prediction: state tax, net investment income tax, qualification and the shareholder's bracket can change it. This example demonstrates why the second layer belongs in the comparison.
Records to bring to the review
- Forecast retained cash and shareholder withdrawals.
- State all company and shareholder rate assumptions.
- Separate deductible pay from dividends.
- Compare multi-year cash and exit outcomes.
Does a 21 percent corporate rate establish that a C corporation is cheaper?
No. The comparison must include shareholder-level treatment, compensation, state tax and how profits ultimately leave the company.
Read this alongside the AE book and published cases
This companion guide provides additional education for readers of C Corporation Tax Strategy. It is not a quotation or chapter excerpt. The worked example is hypothetical and should not be confused with a reported AE client outcome.
Use the AE Tax Advisors c corporation case-study collection to compare the assumptions and supporting records behind published reports. Reported results are publisher statements, not independently audited results or a prediction for another taxpayer. The case-study methodology explains those limits.
