POWER OF ATTORNEY FORMS

Please note, Namely does not require a Power of Attorney for this state at this time. It is not required to file or remit payments on your behalf. If one is needed to resolve a tax matter, the tax notice team will request one from you at that time.

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: D-4

Accepts Fed W-4: No

Comments: Every resident employee must file a Form D-4, Employee Withholding Exemption Certificate, indicating the number of exemptions claimed for withholding purposes. The certificate becomes effective with the first payment of wages or at the beginning of the next payroll period after the D-4 form is provided. If a resident employee does not file a Form D-4, the employer must withhold District of Columbia income tax as if the employee had claimed no exemptions.
