S-Corp vs. C-Corp: Key Differences (2026)

S-Corp vs C-Corp

Краткий ответ

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.

Ключевые отличия

АспектS-CorpC-Corp

Tax treatmentPass-through — profits taxed on shareholders' personal returnsEntity-level corporate tax + shareholder dividend tax (double taxation)

Ownership restrictionsMax 100 shareholders, US citizens/residents only, one share classNo restrictions — unlimited shareholders, foreign investors, multiple share classes

Venture capitalCannot accept VC — investors require preferred stockStandard structure for VC-backed companies

Self-employment taxOwner-employees pay SE tax only on salary, not distributionsOwner-employees pay payroll taxes on salary; dividends not subject to SE tax

Fringe benefitsOwner-employees (>2% shareholders) pay tax on most fringe benefitsOwner-employees can receive tax-free fringe benefits

Formation stateAny state; often Delaware for credibilityDelaware overwhelmingly preferred for VC, M&A, and litigation predictability

ComplexityAnnual S-Corp election (Form 2553), strict compliance requiredBoard meetings, resolutions, cap table management required

Когда выбрать 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

Когда выбрать 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

Итог

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.
