Comparison
S-Corp vs C-Corp
Quick answer
An S-Corp is a pass-through entity that avoids corporate-level federal tax but has strict eligibility rules (max 100 shareholders, US citizens/residents only, one class of stock). A C-Corp pays corporate tax at the entity level but has no ownership restrictions, can issue multiple share classes, and is the only structure that can raise venture capital. For most early-stage companies seeking institutional funding, C-Corp is the default; for profitable small businesses with no VC ambitions, S-Corp can reduce self-employment taxes.

Key differences
When to choose S-Corp
- You are a profitable small business owner who wants to reduce self-employment taxes on distributions above your salary
- You have no plans to raise institutional venture capital
- Your ownership group is under 100 US-person shareholders with no plans to bring in foreign investors
- You want pass-through taxation without the restrictions of a partnership structure
- You are converting from a sole proprietorship or LLC and want a corporate structure with tax efficiency
When to choose C-Corp
- You plan to raise venture capital or angel investment now or in the future
- You want to issue preferred stock, convertible notes, or SAFEs — all of which require C-Corp
- You have foreign founders, employees with options, or plan to bring in non-US investors
- You are building toward an IPO or large acquisition where C-Corp is standard
- You want to retain earnings in the company to fund growth without triggering personal income tax
Which Should You Choose?
If there is any realistic chance you will raise institutional capital, use a Delaware C-Corp from day one — converting later is expensive and creates tax complexity. If you are building a profitable lifestyle business or professional practice with no VC ambitions, an S-Corp election can meaningfully reduce your tax burden. Consult a CPA and business attorney before choosing — the decision has multi-year tax and legal consequences.
