State Income Tax

State Rates and State Income Tax Forms

In addition to the federal income tax system administered by the IRS, 44 individual states operate and collect a marginal state income tax that is similar in many different ways to the federal income tax system. These tax systems generally consist of one or more tax brackets from all individuals, who are a resident or nonresident, that earn an income (wages, investment, interest, etc.) within a particular state’s borders.

In addition, there may be other state benefits that help residents of the states. For example, several states have programs like the earned income credit and other measures to help out lower income residents. However, in order to qualify for any of these programs, a resident must file a state tax return. Also, if you end up paying state income taxes, the IRS allows a deduction for state taxes on your federal tax return. This help alleviate the burden of being taxed by states and the federal government.

Most states also levy some form of corporate income tax (Nevada and Wyoming do not; South Dakota levies a franchise tax on the net income of financial institutions, but has no general corporate income tax; Texas does not have a corporate income tax but does impose a franchise tax upon all taxable entities that do business in the state or that are chartered or organized in the state; Washington does not have corporate income tax, but persons engaged in business in Washington are subject to business and occupation tax).
