MiUI Processes and Capabilities

Can TPA accounts have multiple users with different access levels?

There is only one level of access for TPAs (TPA System Administrator).

Can TPAs connect an employer to their account?

The employer can complete the association or a TPA can request association, in certain circumstances (Professional Employer Organizations / Fiscal Intermediaries), between the employer and TPA accounts. TPA roles can be assigned by an employer directly or requested by a TPA. Employers will have the ability to edit those TPA roles afterwards.

Can TPAs update client level reporting using the upload/import POA?

If a TPA has the Submit Employment and Wage Detail role, they will be able to upload wage files for that client.
