Federal W-4 plus the Idaho Form ID W-4
Idaho employers must keep a federal W-4 on file for each employee. Idaho withholding is calculated from the allowances on the employee's Idaho Form ID W-4, and the Idaho State Tax Commission encourages employees to use the most recent version so that Idaho withholding is updated.
The Idaho child tax credit has ended, so the allowance amount used in the withholding tables is now zero. In practice the allowances on the ID W-4 no longer reduce your withholding.
How Idaho withholding is calculated for 2026
The Tax Commission's percentage method for 2026 withholds 5.3% of the amount above a threshold and nothing below it. For a full year the threshold is $16,100 for single filers and heads of household and $32,200 for married filers, which matches the federal standard deduction for single and married filers. The same thresholds are divided down for each pay period, for example $619 for a biweekly paycheck for a single filer and $1,238 for a married filer.
For example, a single employee earning $60,000 has ($60,000 − $16,100) × 5.3% = about $2,327 of Idaho tax withheld a year.
Bonuses and tables
Idaho taxes bonuses, commissions, overtime and similar pay earned in Idaho. Employers can combine a supplemental payment with regular wages or multiply a separately issued payment by 5.3%. When the Tax Commission issues a new table, employers use it going forward and do not need to adjust earlier paychecks.
