So, what’s the corporate income tax rate united states in 2025? For federal taxes, it’s a flat 21% for most businesses, set by the Tax Cuts and Jobs Act of 2017.

For example, a company earning $100,000 in taxable income pays $21,000 in federal taxes, plus state taxes depending on where it’s based. This rate applies to C corporations, which are businesses taxed separately from their owners. Knowing the corporate income tax rate united states helps you plan your budget, avoid surprises, and maybe even save some money.
What Is the Corporate Income Tax Rate United States?
Let’s start with the basics of the corporate income tax rate united states. This is the percentage a business pays on its profits to the government. In the U.S., taxes for businesses are split into federal and state levels. The federal rate is the same for all companies, but state rates depend on where your business is located.
In 2025, the federal corporate income tax rate united states is a flat 21%. This rate was set by the Tax Cuts and Jobs Act of 2017, which lowered it from 35% to make the U.S. more competitive with other countries. On top of that, 44 states add their own corporate taxes, with rates ranging from 0% in states like South Dakota and Wyoming to 11.5% in New Jersey. Some states, like Nevada and Texas, don’t have a corporate income tax but might charge a gross receipts tax instead, which is a tax on your total sales without deductions.
This tax applies to C corporations—businesses that are taxed separately from their owners. If your business is a pass-through entity, like an LLC or S corporation, your profits are taxed on your personal tax return at individual rates, not the corporate income tax rate united states. Knowing this rate helps you figure out how much you’ll owe and plan your business expenses.
Anecdote: Maria runs a small bakery in Florida, earning $150,000 in profits. She was nervous about the corporate income tax rate united states, but since Florida has no state corporate tax, she only paid the federal 21%—about $31,500. She wanted to find ways to lower that bill even more.
How the Corporate Income Tax Rate United States Works
Now that you know what the corporate income tax rate united states is, let’s talk about how it actually works. It might seem complicated, but it’s really just a process to figure out what your business owes.
Federal Tax Rate Explained
The federal corporate income tax rate united states is 21% on your taxable income. Taxable income is your total revenue minus expenses—like wages, rent, and supplies. So, if your business makes $200,000 in revenue and has $50,000 in expenses, your taxable income is $150,000. At 21%, you’d owe $31,500 in federal taxes.
State Taxes Add On
On top of the federal rate, most states add their own corporate tax. For example:
- New Jersey: 11.5%.
- California: 8.84%.
- Texas: 0% (but has a gross receipts tax).
Your total tax bill combines both federal and state taxes. In New Jersey, a $150,000 taxable income means $31,500 federal tax plus $17,250 state tax—totaling $48,750.
Pass-Through Businesses
Not all businesses pay the corporate income tax rate united states. If you’re an LLC, S corporation, or partnership, you’re a pass-through entity. Your profits “pass through” to your personal tax return, and you pay individual income tax rates, which can go up to 37%.
Anecdote: Jake, a tech startup owner in California, earns $300,000 in profits. His C corporation pays $63,000 in federal taxes (21%) plus $26,520 in California state taxes (8.84%), totaling $89,520. He wished he’d structured as an S corporation to avoid the corporate income tax rate united states.
How the Corporate Income Tax Rate United States Affects Your Business
