Idaho Personal Income Tax Laws

Created by FindLaw's team of legal writers and editors | Last reviewed June 20, 2016

Not all states collect an annual personal income tax, but most do. For the most part, this tax is collected with an annual deadline the same time federal taxes are due (typically April 15). The term "taxable income" refers to all salaries, wages, lottery winnings, profits from stocks, and other types of income that you must claim on your tax returns. Certain sources of income such as child support, welfare, and a certain limit of retirement funds are not taxable.

Most states have a progressive tax structure (instead of a "flat" tax) that taxes higher income amounts at a higher rate. Tax revenue pays for public education, highway maintenance, emergency preparedness, state police, and other shared public resources.
