Why Understanding State Income Tax Rates Is Important

Many taxpayers only focus on federal taxes. However, state income tax rules vary significantly.

Some states use:

• Flat tax rate systems
• Progressive tax brackets
• High-income surtaxes
• No state income tax

If you live in a state with a progressive tax system like California or New York, your income may be taxed at different rates depending on your bracket.
