Unexpected income tax bill this year? Time to review your Idaho W-4 withholding

BOISE, IDAHO — June 24, 2020 — Did you owe more tax than expected when you filed your state income tax return this year? Did you get a smaller-than-expected refund? In either case, it’s a good time to review your paycheck withholding to make sure you’re having the right amount of income tax withheld from your pay. Updating your W-4 now will improve your tax situation when you file next year.

The Idaho State Tax Commission recommends that all employees review their withholding at least once a year or more often to reflect changes in their lives.  

Some life changes include: 

  • Getting married, divorced, or having a child.
  • Having a child become too old for the child tax credit. (A child must be age 16 or under at the end of the year to qualify.)
  • No longer qualifying for the "head of household" filing status. (You got married, or your dependent or child no longer qualifies you.)
  • Working multiple jobs.

You can find the Idaho W-4 and related information on the Tax Commission website at The website includes a link to the federal W-4, so you also can update your federal withholding.
