Income Tax Laws and Rules

Withholding

Idaho law requires employers to withhold income tax from their employees’ wages. If you’re an employee, your employer probably withholds income tax from your pay. You also might see withholding on certain other income — including pensions, bonuses, commissions, and gambling winnings.
