Form HW-4, Employee's Withholding Allowance and Status Certificate, is a legal document completed by an employee for their employer's records to provide information about withholding allowances. If this document is not submitted, the employer will withhold tax from the employee's wages as if the individual is single and claimed no withholding allowances. You have to file a new certificate within ten days if you are divorced or legally separated, your spouse begins claiming their own withholding allowance, or the dependent for whom you claimed a withholding allowance can no longer qualify as a dependent. Submit a new certificate before December 1 if your spouse or dependent dies, unless it happens in December.
This form was released by the Hawaii Department of Taxation. The latest version of the form was issued in 2019 with all previous editions obsolete. You can download a fillable HW-4 Form through the link below.
