Can 8453EX be signed electronically?

Yes. An electronic signature that demonstrates intent, consent, signer attribution, and reproducible retention meets ESIGN and UETA requirements. Maintain the audit trail with timestamp and signer identity to support authenticity.

Who can sign on behalf of the business?

An authorized officer (for example, CEO, CFO, controller) or an agent with a valid power of attorney may sign. Retain evidence of authority such as corporate resolution or POA to substantiate the signer’s authority.

What happens if the EIN is incorrect?

An incorrect EIN can cause identification mismatches and processing delays. It may trigger notices from the IRS and, in certain circumstances, backup withholding if taxpayer identification issues are not corrected.

Is notarization required for 8453EX?

Not necessarily. Notarization depends on the type of supporting documents attached and state rules. If a supporting document requires notarization, comply with state notary or RON rules before submission.

How long must I keep the signed transmittal?

Retain signed transmittals at least three years from the filing date per IRS guidance, extend to six years where understatement of income may apply (IRC §6501(a)). Industry-specific rules may require longer retention.

If an agency requests original documents, what should I do?

Provide the originals as requested and include a copy of the signed 8453EX to link the documents to the e-file. Keep proof of delivery and communication records in your file.

What Business Document 8453EX Is and when it applies

Business Document 8453EX is a transmittal and authorization form used to accompany electronically filed business tax or informational submissions when the filer must provide supporting hard-copy documentation or authorized signature evidence to the IRS or another U.S. federal agency. It records attestation statements, identifies the taxpayer or responsible officer, and documents that the electronic return was prepared and transmitted with the filer’s authorization. Use of this form preserves a paper trail that links electronic submission to signed authorizations and helps agencies reconcile e-filed records with required source documents.

Why 8453EX matters for e-file compliance

Business Document 8453EX creates a signed, auditable connection between an electronically filed business submission and required supporting documents.
