❓ Frequently Asked Questions
What is the federal corporate tax rate in 2026?
The federal corporate income tax rate is 21%, set by the Tax Cuts and Jobs Act (TCJA) of 2017. This flat rate applies to all C-Corporations regardless of income level. There is no graduated bracket system for corporations.
Which states have no corporate income tax?
Nevada, South Dakota, Texas, Washington, and Wyoming have no traditional corporate income tax. However, some impose alternative business taxes. Ohio replaced its corporate income tax with a Commercial Activity Tax (CAT).
How is a pass-through entity taxed differently?
LLCs, S-Corporations, and partnerships are pass-through entities — they don't pay corporate income tax. Instead, profits pass through to the owner's personal tax return. However, this may subject income to self-employment tax (15.3%).
Can I change my state of incorporation to lower taxes?
Yes, but you must consider nexus rules. If you operate in a high-tax state, you may still owe taxes there regardless of where you incorporate. Consult a tax attorney before relocating for tax purposes.
