If a Power of Attorney is requested from you, you should email completed copies of the forms namelyPOA@Namely.com with the CID in the subject line for processing. We will update our system and maintain a copy of each form for record-keeping purposes

STATE INCOME WITHHOLDING FORMS
Namely uploads Federal and State W-4 documents to your HRIS site for use during Onboarding, or if you need to send W-4s to employees who need to make withholding adjustments.
TIP:
The most up to date W-4 documents can be found in the Namely section of the Document dropdown menu in Onboarding and Manage eSignature.
Form Name: HW-4
Accepts Federal W-4: No
Comments: Each new employee must complete a Form HW-4, Employee's Withholding Allowance and Status Certificate, showing the number of exemptions claimed, not to exceed the number of exemptions that the worker is entitled to claim. Federal W-4s are not acceptable. Employers that do not have a Form HW-4 for a worker must withhold as if the employee were single with no withholding exemptions
