Understanding how C-Corporations are taxed is essential for effective business planning and compliance. C-Corporations pay a flat 21% federal tax rate and may also be subject to the Corporate Alternative Minimum Tax (CAMT) under recent tax law changes. However, corporations should be aware of double taxation, where profits are taxed once at the corporate level and again when distributed as dividends to shareholders. 

How C-Corporations Are Taxed

Unlike a Sole Proprietorship, Partnership, or S Corporation, a C Corporation is not a pass-through entity. This means the corporation itself pays taxes on its earnings before distributing any profits to shareholders.

C-Corporations pay a flat federal corporate tax rate of 21% on all profits for tax year 2024. Unlike other business structures, a C Corporation can also retain and reinvest profits within the company for growth, expansion, or other business purposes.

The Corporate Alternative Minimum Tax (CAMT)

While the Tax Cuts and Jobs Act repealed the old Corporate Alternative Minimum Tax (AMT), the Inflation Reduction Act of 2022 introduced a new Corporate Alternative Minimum Tax (CAMT).

The CAMT imposes a 15% minimum tax on the adjusted financial statement income of large corporations with average annual financial statement income exceeding $1 billion.

This rule generally affects only the largest U.S. corporations and aims to ensure that highly profitable companies pay at least a minimum level of tax.

Double Taxation: A Key C-Corporation Disadvantage

One of the main disadvantages of forming a C Corporation is double taxation:

1. The corporation pays tax on its profits.
   
   

2. Shareholders pay tax again on dividends received from those profits.
   
   

C Corporations cannot deduct dividends paid to shareholders as a business expense. Additionally, when profits are distributed, income loses its original character. For example:

• Rental income earned by the corporation becomes dividend income when paid out to shareholders.
  
  

• Even tax-exempt income, such as interest from municipal bonds, becomes taxable dividends once distributed to shareholders.
  
  

Income Sources for C-Corporations

A C Corporation can earn revenue from multiple sources, including:

• Product sales and service income
  
  

• Rental or investment income
  
  

• Dividends or capital gains from investments
  
  

Regardless of the source, all income is first taxed at the corporate level. Any subsequent distribution to shareholders is then taxed again as a dividend.
