UPDATE: Additional information has been added below regarding the 2025 Year End process. Also, a reminder of the deadline to submit requests is December 12, 2025.
2025 Year End
For other State’s income taxes that will be reported on employees’ 2025 W-2 forms, agencies need to submit a request to OFM to configure the State ID number in HRMS.
Review all employees that have withholding taxes from another state and compare the states with the Agency State Income Tax ID’sspreadsheet. If your agency has already reported the State ID number(s) for other states, no action needed. If not, the agency must complete the Employer’s State ID Number form and submit it to HeretoHelp@ofm.wa.gov.
To ensure the information is included in the 2025 Year End process, the request must be submitted to the OFM Help Desk by close of business Friday, December 12, 2025.

Manual adjustments may be required in order for other state taxes to appear on an employee’s W-2.
