New Federal Corporate Tax Rates – 2025 Updated
The corporate tax rate in the United States has changed. Starting in 2025, the federal government replaced the flat tax rate with a new tiered system. This update affects how corporations plan and pay taxes. It matters to small and large businesses alike.
What Is the Corporate Tax Rate?
The corporate tax rate is the percentage a business pays on taxable income. This rate only applies to C-corporations. These are companies taxed as separate legal entities.
C-corporations pay taxes on net income. Net income is what remains after subtracting business expenses, wages, and other deductions. The federal corporate tax rate is fixed nationwide. State tax rates are different in each state.
2025 Federal Corporate Tax Rate Brackets
Before 2025, all C-corporations paid a flat 21 percent federal tax. That rate now depends on how much taxable income the business earns.
Here is the new structure for 2025:
- $0 to $50,000 is taxed at 18 percent
- $50,001 to $100,000 is taxed at 21 percent
- $100,001 to $250,000 is taxed at 24 percent
- Over $250,000 is taxed at 28 percent
This is the current Federal Corporate Income Tax Rate structure. It applies only to income earned starting January 1, 2025.
Why the Federal Corporate Tax Rate Changed
The government needed more tax revenue. It also wanted to give smaller companies some relief. The flat 21 percent rate placed a heavier burden on lower-income businesses.
With this new model, businesses that earn less pay a lower tax rate. Companies with higher profits pay more as income grows. The goal is to balance tax pressure more fairly across different business sizes.
Example: Small Business Tax Savings
Let’s say a small business earns $60,000 in taxable income. Under the old system, it would pay:
- $60,000 × 21% = $12,600
Under the new 2025 structure:
- First $50,000 × 18% = $9,000
- Next $10,000 × 21% = $2,100
- Total tax = $11,100
That’s a savings of $1,500. That money can go toward payroll, supplies, or other costs. This new corporate income tax rate benefits smaller operations right away.
Example: Larger Corporation Pays More
Now consider a company with $500,000 in taxable income. Under the old rate:
- $500,000 × 21% = $105,000
Under the 2025 brackets:
- First $50,000 × 18% = $9,000
- Next $50,000 × 21% = $10,500
- Next $150,000 × 24% = $36,000
- Final $250,000 × 28% = $70,000
- Total tax = $125,500
That is an increase of $20,500. Businesses at this level will need to adjust forecasts and plan for the higher rate.
What remains unchanged in the New Federal Corporate Tax Rate of 2025?
Deductions and credits still apply. Businesses can lower taxable income using qualified expenses, such as:
- Equipment depreciation
- Health insurance for workers
- Office rent
- Business travel
- Software or service subscriptions
- Charitable contributions
Credits reduce the tax owed. Popular ones include:
- Research and development credit
- Clean energy investment credit
- Veteran hiring credit
These tools help lower the effective corporate tax rate. That means a company may still pay less than the stated bracket amount after applying for these benefits.
State Corporate Income Tax Still Applies
Most states also charge a corporate income tax rate. Some use flat rates. Others use their own brackets. A few states, like South Dakota and Wyoming, charge no corporate tax.
Here are examples of current state rates:
- California: 8.84%
- New York: 7.25%
- Texas: 0% (franchise tax applies instead)
Businesses must pay both state and federal taxes unless located in states with no corporate tax. The combined total can reach 30 percent or more in some places.
How the IRS Handles the Change
The IRS updated forms and software to match the new tax brackets. Corporations need to make sure they use the latest tax tools for calculating estimated payments.
Businesses must also track deductions and credit claims closely. The IRS may increase checks on large corporations that pay much less than the statutory rate.
Planning Tips for Businesses
Companies should take action now to stay on track:
- Estimate your 2025 taxable income
- Use the correct bracket for each income tier
- Apply all eligible deductions and credits
- Adjust estimated payments for the higher or lower rates
- Keep records clear and organized
Meeting with a tax advisor may help. Every business has different income patterns, deductions, and needs.
Even after the 2025 change, the United States does not have the highest corporate tax rate. Some countries tax corporations at a lower rate, but many others go higher when local taxes are added.
The combined federal and state corporate tax rate in the US now ranges from 25 percent to 32 percent, depending on location. This keeps the US in line with other major economies.
