If the applicant is a parent entity applying on behalf of multiple subsidiaries and it would like each subsidiary to receive its own payment, the applicant should create an Optum ID account and submit an application for each TIN that should receive its own payment. The applicant should include the unique banking information for each subsidiary’s application.
If the applicant is a parent entity applying on behalf of multiple subsidiaries and it would like a single payment for all of the included subsidiaries, the applicant should create one Optum ID account for the parent entity and submit a single application with the filing TIN.
The parent entity should add its TIN as the “Organizational TIN” on their dashboard. If applying on behalf of subsidiaries, the parent entity will have the opportunity to enter multiple subsidiary TINs associated with the parent organization TIN. After adding the “Organizational TIN,” the applicant should click “Get Started” once they arrive on the “Practice Detail” page, under the “Group/Individual Information” heading. The applicant can enter up to 1,200 subsidiary TINs into the “List of Subsidiary TINs Associated with This Entity” field.
The applicant may paste a list of TINs directly into this field. Next, the applicant should review their information and click “Submit TIN.” Once the organization or subsidiary TINs are verified, the applicant will progress to the DocuSign form, where they can submit the applicable tax information that accounts for each TIN included in the application.
