Use this guide to understand the changes to corporate taxes and the steps you can take to minimize your tax burden in 2024 and beyond. 

Notable corporate income tax changes in 2024

Did the corporate tax rate change? Review notable changes and issues surrounding the federal and state corporate tax rate.

Federal

The federal corporate income tax rate of 21% remains unchanged from the previous year, with 2024 being relatively quiet in terms of notable changes. However, with a new administration assuming control of Washington in 2025 and the potential expiration of TCJA, some experts expect more sweeping federal corporate tax changes in the future.

State

Arkansas, Iowa, Kansas, Nebraska, New Jersey, and Pennsylvania all had reductions in their corporate tax rates starting in January. A handful of other states made retroactive changes to their corporate tax rates that impacted the 2023 tax year

How Will Corporate Income Tax Rates Change After TCJA Expires?

Trillions of dollars in tax breaks will expire with the TCJA if Congress fails to take action. These tax breaks include: 

  • Lower tax brackets

  • Higher standard deductions

  • Large child tax credit

  • Bigger estate and gift tax exemptions

  • 20% tax break for pass-through businesses

The outcome of the 2024 US elections has provided some clarity regarding the direction of future corporate tax rates. During the campaign, Vice President Kamala Harris proposed a 28% corporate tax rate, while President-elect Donald Trump supported corporate tax rates of 15% and 20%.

According to the Bipartisan Policy Center, "TCJA stands as the most substantial overhaul of the business tax code in decades. Though many business provisions in TCJA are permanent law, several continue to inspire debate and deliberation among lawmakers, experts, and the business community, such as the tax treatment of R&D and bonus depreciation."

Federal corporate income tax rate

Since the TCJA was passed, the federal corporate tax rate has been 21%. This rate applies to taxable income, a small business's revenue minus expenses.

Calculating your federal corporate income tax burden is simple. In this example, the annual revenue is $100,000, and the expenses are $20,000.

1) Subtract expenses from your revenue.
$100,000 - $20,000 = $80,000 in taxable income.

2) Multiply your taxable income by the federal tax rate.

$80,000 x .21 = $16,800 you owe in federal corporate taxes.

State corporate income tax rate

Most businesses do not pay corporate income taxes because they are pass-through entities, including limited liability companies (LLCs) and partnerships. Businesses with this status pass income and deductions to the business owners, who must report their distributions on their personal income tax returns. If your business entity lacks a pass-through taxation feature, such as those formed as C corporations, you will likely be responsible for paying corporate income taxes both state and federally. While most states have a corporate income tax, South Dakota and Wyoming don't have any corporate tax.

Corporate Tax FAQ

How do pass-through entities’ federal taxes work?

Pass-through entities are not taxed at the federal level on business income. Instead, profits are passed through to ownership to be handled on their individual income tax returns. Generally, the personal income tax rate is more favorable than a federal corporate tax rate for owners. 

What are non-taxable corporate transactions?

Certain corporate transactions are considered non-taxable, meaning some business activities are not subject to taxation. Corporate acquisitions where the buyer pays a seller mostly in stock are considered one of the more common examples of a non-taxable transaction. 

What is the TCJA?

The TCJA, or Tax Cuts and Jobs Act, is a series of tax reforms and cuts passed in 2017 that will begin expiring in 2025. Due to the outcome of the 2024 US elections, there is an expectation that the TCJA will be extended in 2025, but no formal plans or details have been presented.  

Could the TCJA be renewed in 2025?

Yes, there's a strong possibility that the TCJA, or Tax Cuts and Jobs Act, will avoid expiration in 2025. The new administration, which presided over the country during the introduction of the TCJA, is expected to opt to extend these tax cuts. 

Is there any pending legislation that will change tax rates in 2024?

Tax changes can occur throughout the year, with some retroactively applied to previous years. Federal and state corporate tax rates are expected to remain unchanged for the remainder of 2024. 

What is withholding tax?

The money employers deduct from their W-2 employees' gross wages and pay directly to the government is known as a withholding tax. The withheld amount functions as a credit to be applied to a W-2 employee's federal income taxes. W-2 employees will receive a tax refund if too much money is withheld throughout the fiscal year and may owe the Internal Revenue Service (IRS) if too little is taken out.
