The Washington Initial Report is a mandatory reporting process for employers in the state of Washington. It is part of the state's Unemployment Insurance (UI) program and is used to determine an employer's eligibility and contribution rate for UI taxes. There are two types of Washington Initial Reports: the New Employer Report and the Quarterly Report. The New Employer Report is used by employers who are new to the state or who have not been covered by the UI system in the past. This report is used to register the employer in the UI system and to determine their initial contribution rate. The Quarterly Report is used by existing employers to report their wages and contributions each quarter. This report is used to update the employer's contribution rate and to calculate the amount of UI taxes they owe. Both reports must be filed electronically through the Washington State Employment Security Department's website.
