What is the Idaho Single income tax filing status?

There are five filing status available to Idaho state taxpayers: Single, Married Filing Jointly, Married Filing Separately, Head of Household, and Qualifying Widow. These five filing status are visible as check boxes on both the IRS Form 1040 and the Idaho Form 40.

Single is the filing type you select if you are not married, do not have children, and have no dependants for example. Filing as Single generally results in paying higher federal and Idaho state income tax rates compared to the other four filing statuses.

Single status tax payers in most states have a relatively lower standard deduction and fewer family oriented credits available to reduce their income tax liability.
