In plain English
A corporation is created under state law. Its owners are shareholders, who exchange money, property or both for the corporation's stock. The tax code defines a C corporation simply as a corporation that is not an S corporation for that year. For federal tax purposes, a C corporation is its own taxpayer. It files Form 1120 and pays tax on its taxable income.
Profit is taxed to the corporation when it is earned, then taxed to shareholders when it is paid out as dividends. The corporation gets no deduction for the dividends it pays, and shareholders cannot deduct the corporation's losses. That is the double taxation people talk about.
An LLC can also choose to be taxed as a corporation by filing IRS Form 8832. It stays an LLC under state law. Taxed as a corporation without an S election, it files Form 1120 like any C corporation.
Example
Why it matters
Double taxation makes a C corporation sound like a mistake. It is not automatically one. A C corporation is not subject to the S corporation limits on how many shareholders it can have, what kinds of owners it can have, or how many classes of stock it can issue. Corporations can raise money by selling stock. That can matter for a business planning to bring in outside investors or eventually sell. Whether it fits is a question for a CPA and an attorney.
Where people get confused
"Corporation" and "C corporation" are not quite the same thing. Corporation describes the legal entity your state creates. C and S describe how the IRS taxes it. A corporation that elects S status is still a corporation.
Owners who work in the business are not paid the way sole proprietors are. Under federal employment tax rules, corporate officers who perform services and receive payments for them are employees, and those payments are wages.
