Tax E-filing Authorization
What a Tax E-filing Authorization Is and Why It Matters
Key Reasons to Use a Formal Authorization
A clear Tax E-filing Authorization reduces processing delays, establishes legal consent for electronic filing, and creates an auditable record of who may file and which returns are authorized. Proper documentation helps avoid backup withholding, filing rejections, and disputes over filing authority.
Who Typically Completes a Tax E-filing Authorization
Typical users include individual taxpayers, CPAs, enrolled agents, payroll providers, and authorized corporate officers who delegate e-filing duties.
- Individual taxpayers delegating a preparer to file federal and state returns.
- Tax professionals authorizing electronic filing for multiple clients in one workflow.
- Employers granting payroll providers authority to e-file W-2s and 1099s.
Confirm signer capacity (owner, authorized officer, or power of attorney) and include an effective period to prevent unauthorized filings.

Common Preparation Pitfalls to Avoid
- Using an authorization that omits the taxpayer identification number or lists an incorrect TIN, triggering IRS TIN matching failures and backup withholding risks.
- Authorizing a broad ongoing e-filing power without clear expiration or scope, which can lead to disputes or unauthorized filings after relationship termination.
- Failing to attach required supporting documents such as a valid power of attorney or W-9, causing preparers or payers to reject the electronic submission.
- Relying on weak signer authentication (email-only) for high-risk tax filings instead of stronger methods like SMS code, KBA, or SSO.

Frequently Asked Questions about Tax E-filing Authorization
-
Is an e-signature legally valid?
Yes. Under the ESIGN Act (15 U.S.C. ch. 96) and UETA where adopted, electronic signatures that demonstrate intent, consent, attribution, and retention are legally binding. Exceptions such as wills and some court filings may apply; verify any statutory exceptions.
-
Do I need notarization for the authorization?
Not always. Notarization is required only when state law or the recipient demands it. If a POA or a specific payer requires a notarized authorization, use in-person notarization or RON where your state permits remote notarization.
-
How long must I retain signed authorizations?
Retain signed authorizations per applicable statutes: at least three years for IRS-related records (IRC §6501(a)), six years for HIPAA-covered documents (45 CFR §164.530(j)), and longer if contract or state law requires it. Consult counsel for specifics.
-
How can I revoke an authorization?
Revoke in writing, date the revocation, and send it to the preparer and any payers. State the effective revocation date, request written confirmation of receipt, and retain copies. For urgent revocation, notify payer and IRS channels as needed.
-
What confirms a corporate officer can sign?
Confirm authority by title, corporate resolution, or an attached POA. Include the officer's printed name, title, and an explicit statement of corporate authority to delegate e-filing to avoid challenges.
-
Can I use Remote Online Notarization (RON)?
Possibly. Most states permit permanent RON but rules vary. If notarization is required and your state allows RON, use a compliant vendor that performs identity-proofing, AV recording, and retains session records per state rules.
