S Corp or C Corp: Picking the Right Tax Structure for Your Business

How C Corps Are Taxed

A C corporation is its own taxpayer. It pays a flat 21% federal tax on its profits. If it then distributes those profits to shareholders as dividends, the shareholders pay personal income tax on that same money again. That’s the double taxation people talk about, and it’s the main downside of the C corp structure for a small, closely held company that just wants to pay its owners.

How S Corps Are Taxed

An S corporation avoids that. It’s a pass-through entity, meaning the business itself generally doesn’t pay federal income tax. Instead, profits and losses flow through to the owners’ personal returns, and tax gets paid once, at the individual level.

S corp owners who work in the business also get a nice side benefit: they can split their income between a reasonable salary (subject to payroll tax) and additional distributions (not subject to payroll tax), which is a common way small business owners reduce their self-employment tax burden.

So Why Would Anyone Choose a C Corp?

A few real reasons:

• Raising venture capital: Most institutional investors want a C corp, partly because S corps can’t have more than 100 shareholders, can’t have corporate or foreign shareholders, and can only issue one class of stock — none of which works well with how VC deals are structured.
• Reinvesting profits: If you want to reinvest most of your profits back into the business rather than distribute them, the flat 21% C corp rate can actually beat individual rates depending on your income level.
• QSBS eligibility: If you’re hoping to eventually qualify for the QSBS exclusion, that benefit is only available through C corp stock. S corp stock doesn’t qualify, full stop.

The Practical Trade-offs

• S corps come with ownership restrictions and stricter compliance requirements around reasonable salary, which the IRS pays close attention to.
• C corps have more flexibility on ownership and stock structure but carry the double taxation risk and more complex compliance generally.

So Which One Fits?

• If you’re a service business with a handful of working owners who want to minimize self-employment tax and keep things simple, S corp is usually the better fit.
• If you’re building something you intend to scale fast, bring in outside investors, or eventually sell for a large gain, C corp deserves serious consideration, especially with QSBS now offering even better terms than it used to.

Bottom Line

This isn’t a decision to make off a quick online comparison chart. The right answer depends heavily on your growth plans, your income level, and your exit strategy.
