What Is the Corporate Tax Rate? [Federal & State Guide]

Your company’s tax liability largely depends on the business structure you choose. And if you structure your business as a corporation, you’re responsible for paying the corporate income tax rate on company earnings. So, what is the corporate tax rate?

How do corporation taxes work?

A corporation, or C Corp, is a business structure where owners enjoy limited liability protection. Corporations are separate legal entities, meaning they are separate from their owners. Owners are not responsible for their corporations’ actions and debts (hence limited liability).

Because corporations are separate legal entities, corporations are subject to double taxation. The company pays taxes on its earnings and the owner also pays taxes. In other business structures (e.g., sole proprietorships), taxes pass through to the owner so they only pay taxes on earnings once.

How do corporate taxes work? Corporations are taxed and business owners are taxed

If you own a corporation, report its profits and losses on Form 1120, U.S. Corporation Income Tax Return. And, report your personal income on your individual tax return.

Corporations are generally taxed at both the federal and state level. When a corporation pays taxes on its taxable income, it must pay at a rate set by both the federal and state levels.

So if you structure as a corporation, you need to know the corporation tax rates.

Incorrectly calculating your tax liability is one mistake you don’t want to make.

What are corporate tax rates?

Again, there are both federal and state corporation tax rates.

The federal corporate tax rate is a flat rate that applies to all businesses. On the other hand, state tax rates vary by state.

So, how much are corporate taxes? 

Federal corporate income tax rate

First things first: what is the federal corporate tax rate? The current corporate tax rate (federal) is 21%.

Prior to the 2017 Tax Cuts and Jobs Act of 2017, there were taxable income brackets, and the maximum tax rate was 35%. The Tax Cuts and Jobs Act slashed the tax rate from 35% to 21%. In March 2024, President Biden proposed raising the corporate income tax rate from 21% to 28%, so stay tuned.

The corporate tax rate applies to your business’s taxable income, which is your revenue minus expenses (e.g., cost of goods sold).

Federal corporate tax rate example

Let’s say you have annual revenues of $250,000 and qualifying expenses of $55,000. You want to figure out how much you owe in federal taxes.

First, subtract your expenses from annual revenues:

Taxable Income = $250,000 – $55,000  

Taxable Income = $195,000 

Next, multiply the federal corporate tax rate of 21% (0.21) by your taxable income:

$195,000 X 0.21 = $40,950

You would owe $40,950 in federal corporate taxes.

State C Corp tax rates

Most states set a corporate tax rate in addition to the federal rate. State corporate income tax rates range from 0% – 9.8%. But, not all states levy a corporation tax rate.

The following states do not have a state corporate tax rate:

  1. Nevada
  2. Ohio
  3. South Dakota
  4. Texas
  5. Washington
  6. Wyoming

Nevada, Ohio, Texas, and Washington levy gross receipts taxes on corporations instead of corporate taxes. A gross receipts tax is a tax on a business’s gross receipts, which includes the business’s total revenue without deductions (e.g., operating expenses). 

South Dakota and Wyoming do not have state corporate income taxes at all. 

Some states have both corporate income tax and gross receipts tax. 

Some states apply a flat tax to all corporations while others use brackets. The states with brackets apply tax rates based on the corporation’s taxable income.

How to decrease your corporate income tax liability 

You can reduce your corporate tax liability by deducting qualifying business expenses from your taxable earnings.

Another way you can change up your tax liability is by choosing a business structure that does not impose double taxation. For example, structuring as an S corporation is an alternative to structuring as a C Corp.
