Each pay period is calculated separately. A dash means the current per-paycheck deductions exceed pay at that frequency. Annualized pay repeats the selected paycheck; actual yearly totals can differ near wage and contribution limits.

Assumptions and sources
- One employer; work and residence are in the selected state.
- Missing YTD wages are projected from the selected pay date and current pay pattern.
- Idaho uses the revised 2026 percentage method issued in July and rounds state withholding to whole dollars.
- Idaho Child Tax Credit withholding allowances are zero after the credit sunset, so the allowance count does not change this schedule.
- The earlier 2026 Idaho schedule is not implemented; pay dates before July 31 are unavailable.
