Tax Submission Authorization Form
What the Tax Submission Authorization Form Is
Why a Clear Authorization Matters for Tax Filings
A clear, signed authorization reduces processing delays, helps establish consent for electronic filing, and documents who may receive tax documents or submit returns on behalf of the taxpayer. Proper authorization also supports audit trails and helps resolve disputes about filing responsibility or data disclosure.
Who Typically Completes This Authorization
The form is commonly completed by individuals, small business owners, and organizations that delegate tax preparation or submission to agents, payroll providers, or third-party payers.
- Independent contractors and freelancers who authorize a payer or agent to file 1099s on their behalf.
- Small business owners who grant an accountant or payroll vendor permission to prepare and e-file returns.
- Nonprofit treasurers or fiduciaries who delegate filings to contracted tax preparers or volunteers.
Use the form whenever a named agent will access or submit tax data; retain a signed copy to document consent and scope for compliance and audit purposes.
Primary Signers and Parties
Taxpayer — Individual
The person whose tax data appears on the return. They must sign to grant authority; for business returns, an authorized officer or owner signs. Accurate legal name and TIN are essential to avoid backup withholding or incorrect filing.
Authorized Agent — Professional
A CPA, enrolled agent, payroll provider, or third-party designee authorized to prepare or file tax returns. The agent should provide contact information, their preparer tax identification number (PTIN) when applicable, and the precise scope of authority.

Technical Considerations for eSubmission and Signing
Choose a platform that supports secure e-signing, strong authentication, and long-term retention for tax records.

Key Filing Deadlines and Timing to Remember
W-9 provision:
Provide upon payer request; no fixed filing date
1099-NEC:
Recipient and IRS due Jan 31 each year
1099-MISC:
Recipient due Jan 31; paper IRS Feb 28; electronic Mar 31
Form 1040:
Due April 15; extension to Oct 15 with Form 4868
FBAR (FinCEN 114):
Due Apr 15 with automatic extension to Oct 15
Common Preparation Errors to Avoid
- Providing a mismatched name or TIN that triggers backup withholding or IRS correction requests, delaying processing and risking penalties.
- Using vague authorization language that fails to specify which forms or years the agent may prepare or file, creating ambiguity for payers or auditors.
- Failing to attach required supporting documents (W-9, identity proof) or to set conditional fields for attachments in digital workflows, leading to incomplete submissions.
- Collecting signatures without a demonstrable audit trail or consent record, weakening enforceability under ESIGN and UETA in disputes.

Practical Tips for Reliable Authorizations
Frequently Asked Questions About Tax Submission Authorizations
-
Are e-signatures legally valid?
Yes. Electronic signatures meet legal standards under the ESIGN Act (15 U.S.C. ch. 96) and UETA where adopted, provided intent, consent, attribution, and retention requirements are met.
-
What if the TIN is incorrect?
An incorrect TIN can trigger backup withholding at 24% and IRS notices. For information returns, penalties under IRC §6721 may apply for incorrect filings.
-
Is notarization required?
Notarity is not generally required for tax authorizations, but state rules or attached documents (durable POA, deeds) may require notarization or witnesses.
-
How do I revoke authorization?
Revoke in writing, send notice to the agent and payers, and retain proof of delivery. Specify an effective revocation date and remove electronic access immediately.
-
Can an agent e-file for multiple years?
Yes if authority explicitly covers multiple tax years. State scope clearly to prevent accidental overreach and to align with retention obligations.
-
How long should records be kept?
Retain authorizations at least as long as the related tax records. IRS baseline: 3 years from filing (IRC §6501(a)); longer retention may be required for audits or industry rules.
