Signed Authorization
Executed power of attorney or equivalent form specifying representatives, scope, effective dates, and any limitations; include witness or notarization when required by jurisdiction or the receiving agency.
Maintaining a complete Tax Representation Portfolio clarifies authority, reduces delays in responding to IRS or state notices, documents consent for disclosures, and helps manage liability by recording scope and limitations of representation.
Use of a portfolio helps all parties confirm authority, manage communications with tax agencies, and meet documentation and retention expectations.
Enrolled agents, CPAs, and tax attorneys serve as the designated representative; they should keep a copy of the signed authorization, verify identity, and record the scope of authority in the portfolio.
The taxpayer signs the authorization and provides identity documents and relevant returns; the portfolio should reflect the taxpayer's legal name, TIN, and explicit consent to representation.
Executed power of attorney or equivalent form specifying representatives, scope, effective dates, and any limitations; include witness or notarization when required by jurisdiction or the receiving agency.

Engagement letter or service agreement that defines responsibilities, fee structure, confidentiality, and termination terms tied to the representation.
