C Corporation Double Taxation Explained

A C Corporation offers business owners a separate legal structure, limited liability protection and flexibility in raising capital. However, one important tax consideration is C Corporation double taxation.

Unlike businesses that generally use pass-through taxation, a C Corporation is typically taxed separately from its shareholders. The corporation pays federal income tax on its taxable profits. If it distributes its after-tax profits to shareholders as dividends, shareholders may also owe individual income tax on those dividends.

This two-level tax treatment is commonly called double taxation.

For U.S. business owners, understanding how this process works is important when deciding how to structure a business, distribute profits and plan for long-term growth.

What Is Double Taxation in a C Corporation?

Double taxation in a C Corporation refers to the potential taxation of corporate profits at two different levels:

• Corporate level: The corporation pays income tax on its taxable profits.
• Shareholder level: Shareholders may pay individual income tax when the corporation distributes those after-tax profits as taxable dividends.

A C Corporation is treated as a separate taxpayer for federal income tax purposes. Its shareholders do not generally report the corporation's ordinary business profits directly on their individual returns merely because they own shares.

Instead, the corporation reports its taxable income and pays applicable corporate income tax. When it distributes earnings as dividends, shareholders generally report taxable dividend income on their individual tax returns.

The corporation generally cannot deduct dividends paid to shareholders as a business expense. This is why the same underlying corporate earnings can be subject to tax at both levels.

For a broader explanation of the business structure, see our guide to how a C Corporation works.

How Does C Corporation Double Taxation Work?

C Corporation double taxation generally occurs through the following process.

Step 1: The Corporation Earns Taxable Income

A C Corporation generates income through its business activities. After applying allowable deductions and other applicable tax adjustments, the corporation determines its taxable income.

The general federal corporate income tax rate is 21% under Section 11 of the Internal Revenue Code.

The corporate tax is calculated on taxable income, not simply on gross revenue.

For a detailed explanation of the corporate tax calculation, see our guide to the C Corporation federal tax rate.

Step 2: The Corporation Pays Federal Income Tax

The corporation calculates and pays its applicable federal income tax.

For example, assume a C Corporation has $100,000 in taxable income and qualifies for the general 21% federal corporate income tax rate.

The corporation has $79,000 remaining after the illustrative federal corporate tax, before considering any other applicable taxes, liabilities or business decisions.

Step 3: The Corporation Distributes Profits to Shareholders

The corporation may decide to distribute some or all of its available after-tax profits to shareholders as dividends.

For example, assume the corporation distributes the entire $79,000 to its shareholders as a dividend.

The dividend is not deductible by the corporation. Therefore, the corporation's payment of dividends does not reverse the corporate income tax already paid.

Step 4: Shareholders May Pay Tax on Dividends

Individual shareholders who are U.S. citizens or resident aliens generally report taxable dividends on their individual federal income tax returns.

The applicable tax treatment depends on whether the dividends are qualified or nonqualified, the shareholder's income and filing circumstances, and other relevant tax rules. Corporate shareholders may be subject to separate dividend tax rules. Dividends paid to nonresident alien shareholders are generally subject to U.S. withholding tax, which may be reduced under an applicable tax treaty.

This creates the second level of taxation.

How Are C Corporation Dividends Taxed?

When a C Corporation distributes profits to shareholders, the tax treatment generally depends on whether the distribution qualifies as a dividend and how the dividend is classified for individual income tax purposes.

Qualified Dividends

Qualified dividends may be eligible for preferential federal tax rates rather than ordinary income tax rates.

Generally, qualified dividends must meet requirements relating to the paying corporation, the type of dividend and the shareholder's holding period. For most common stock, the shareholder must generally hold the stock for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date. Certain preferred stock is subject to a different holding-period requirement.

For example, dividends paid by an eligible U.S. corporation may qualify if the shareholder satisfies the applicable holding-period and other statutory requirements.

The maximum federal tax rates that generally apply to qualified dividends are 0%, 15% or 20%, depending on the taxpayer's circumstances and applicable tax-year thresholds.

Ordinary or Nonqualified Dividends

Nonqualified dividends are generally taxed at the shareholder's ordinary income tax rates.

A dividend does not automatically qualify for preferential treatment simply because it is paid by a U.S. corporation.

The shareholder should review the dividend information reported by the corporation, including Form 1099-DIV where applicable, and determine the correct treatment on the individual tax return.

Are All Shareholder Distributions Taxable Dividends?

No. Not every payment or distribution made by a corporation to a shareholder is automatically treated as a taxable dividend.

The tax treatment generally depends on the corporation's current and accumulated earnings and profits, the shareholder's stock basis and the nature of the transaction.

A distribution that is not treated as a dividend may reduce the shareholder's stock basis. Any amount exceeding the applicable basis may result in a taxable gain.

Therefore, business owners should not assume that every shareholder payment has the same tax treatment.

How Does C Corporation Double Taxation Compare With S Corporation Taxation?

One major difference between C Corporations and S Corporations is how business income is generally taxed for federal income tax purposes.

A C Corporation generally pays corporate income tax on its taxable income. Shareholders may then pay individual income tax when the corporation distributes taxable dividends.

An eligible S Corporation generally uses pass-through taxation. Its income, deductions, credits and other applicable tax items generally pass through to shareholders, who report their allocated amounts on their individual tax returns.

An S Corporation does not automatically eliminate every form of entity-level tax. Certain S Corporations may be subject to specific federal taxes, and state tax treatment can differ.

S Corporation eligibility requirements include restrictions on shareholder types. Nonresident aliens generally cannot be S Corporation shareholders.

Similarly, S Corporation shareholders may owe tax on allocated income even when the business does not distribute cash to them.

The appropriate structure depends on the business's ownership, profitability, financing plans, shareholder circumstances and compliance requirements.

Conclusion

C Corporation double taxation is an important consideration for U.S. business owners because corporate profits may be taxed once at the corporate level and again when distributed to shareholders as taxable dividends.

However, the actual tax burden depends on more than the general corporate tax rate. Dividend classification, shareholder income, distribution decisions, state tax obligations and the company's long-term financial plans can all affect the outcome.

Before choosing a C Corporation structure or deciding how to distribute profits, business owners should evaluate the corporate and shareholder tax consequences together.
