State Treatment	Some states impose entity-level tax or fail to recognize S status.	All states recognize C corporation taxation uniformly.

Common Examples	Family-owned restaurants, local real estate firms, and small consultancies.	Google, Apple, Microsoft, and most publicly traded enterprises.
Typical Users	US-based small businesses with fewer than 100 individual owners.	Startups seeking venture funding or firms planning public listing.
Limitations	No foreign owners, no corporate shareholders, and strict deadline for election.	Double taxation and heavier administrative formalities burden owners.
Best-Fit Scenario	Profitable small business with few US owners wanting single taxation.	High-growth venture needing outside investment and eventual IPO.

What Is S Corp?

S Corp is a special tax election available to domestic corporations. It allows business income, deductions, and losses to pass through to shareholders, avoiding double taxation. S Corp exists to help small businesses save on taxes while keeping corporate liability protection.

Definition of S Corp

An S Corporation is a corporation that elects to be taxed under Subchapter S of the Internal Revenue Code. It passes corporate income, losses, deductions, and credits through to shareholders for federal tax purposes, so shareholders report business activity on personal tax returns.

Key Characteristics of S Corp

Characteristic	What It Means in Practice
Pass-through taxation	Profits and losses flow to shareholders, who report them on personal tax returns.
100-shareholder limit	Only up to 100 shareholders are allowed, keeping the ownership group small.
Single class of stock	All shares carry identical rights, so no preferred stock or varying dividends are permitted.
US citizen requirement	Shareholders must be US citizens or resident aliens; non-residents cannot own shares.
Reasonable salary rule	Owner-employees must pay themselves a market-rate salary before taking distributions.
Calendar year required	The tax year must be a calendar year unless a valid business purpose justifies otherwise.

C Corp is a legal business structure where the company is taxed separately from its owners. It exists to allow businesses to raise capital by selling stock to unlimited investors while providing owners with limited liability protection.

Definition of C Corp

A C Corporation is a legal entity chartered under state law that files a federal corporate income tax return using Form 1120, pays taxes on its profits at corporate rates, and distributes after-tax earnings to shareholders as taxable dividends.
