Most states levy an income tax on their residents that is in addition to the federal income tax. Laws vary from state to state but in most states the state income tax is a tax on the annual earnings of individuals, corporations, trusts, limited liability companies, and other legal entities.
There are nine states that do not have a state income tax—including Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. But New Hampshire levies a tax on capital gains and Washington state recently enacted a tax on extraordinary profits from the sale of financial assets over $250,000.
In Kansas (KS), residents are subject to state income tax in addition to the federal income tax. The Kansas state income tax applies to the annual earnings of individuals, corporations, trusts, limited liability companies, and other legal entities. The tax rates and brackets for individuals are progressive, meaning that the rate increases as income rises. Corporations are taxed at a flat rate. Kansas provides various deductions, credits, and exemptions that can affect the overall tax liability for residents and businesses. Unlike the nine states mentioned that do not have a state income tax or only levy taxes on certain types of income, Kansas has a more comprehensive state income tax system that encompasses a range of income sources.
