Regular withholding (aggregate method).
- 0% on the first $10,000 of taxable income, 4.0% above (formula 'For Periods In 2026')
- No tax withheld from regular wages -> must aggregate; otherwise may aggregate
- If that substantially over-withholds, may use the highest bracket the employee is expected to reach (4.0%)
If the procedures set forth above result in substantial over withholding, the amount to be withheld may be computed at the percent corresponding to the highest tax bracket the employee is expected to reach.
