Idaho’s 1999 income tax on working-poor and near-poor families:
No tax on families with incomes at the poverty line ($17,028 for family of four, $13,290 for family of three).
No tax on families of three or four with full-time minimum-wage earnings ($10,712).
For families of four with incomes at 125% of the poverty line ($21,285): $87.	17th lowest

Idaho has consistently exempted families with below-poverty earnings from the income tax. In 1991, a family of four owed no tax until its income reached 3 percent above the poverty line. Idaho’s tax threshold is now 8 percent above the poverty line.
