Here’s what HIVE AI had to say about “Electronic signature requirements for tax documents”:

Electronic signature requirements for tax documents

Statutory authority to accept e-signatures

• The IRS is authorized to accept digital or other electronic signatures and to publish standards for their use. Documents signed under an IRS-adopted electronic method are treated the same as ink signatures for all civil and criminal purposes, including penalties of perjury 1.

General IRS program rules for e-signatures

IRS e-Signature Program and accepted methods

• IRS programs accept various electronic methods depending on the form and program, including: checkbox selection (e.g., Form 8655), PIN entry (e.g., Forms 1040, 1065, 1120, 2290, 8878/8879 families), electronic signature pads, stylus-captured signatures, voice signatures (Form 8850), and scanned/digitized images of handwritten signatures (e.g., 8879-F). The IRS publishes which forms accept which e-signature method in IRM 10.10.1 2.
• IRS Chief Counsel has stated there’s no legal bar to accepting faxed, scanned, electronic, or digital signatures; acceptance is a business decision and may require stronger authentication for higher‑risk documents 3. IRS has also advised to balance e-signature use against disavowal risk and to implement heightened authentication and signing processes for high‑risk documents 4.

Tax return and preparer signature rules

Preparer signature requirements with e-file

• A signing preparer must sign completed paper returns before presenting to the taxpayer. For electronically signed returns, the preparer need not sign before presenting the completed copy, but must furnish all information that will be transmitted along with Form 8879 (or similar e-file signature form) when obtaining the taxpayer’s authorization 5.
• Publication 1345 governs e-file providers. For Forms 8878/8879 e-signatures, software must retain a digital image of the signed form, date/time, IP address and username for remote transactions, identity verification results (KBA or in‑person ID check), and an audit trail of the signature method. EROs must produce this evidence to IRS upon request. Identity proofing should meet NIST SP 800‑63 Level 2 for remote e-signing 6.

Taxpayer signature acknowledgments and disclosures

• When taxpayers sign Form 8879 or the return, they acknowledge under penalty of perjury that the return is true, correct, and complete; this is part of the e-file process and disclosures the IRS expects providers to communicate 7.

Third‑party authorizations and disclosures

Form 2848 (POA) and 8821 (TIA)

• The IRS now accepts electronic signatures for POA and TIA, aligning with the Taxpayer First Act’s directive to provide digital signature options. Tax Pro Account and online submission allow e-signed authorizations to be uploaded and processed 8.
• Form 8821: Acceptable e-signature methods include typed name in the signature block, digitized/handwritten image, signature pad, stylus, or third‑party e-sign tools. For remote e-signing, a third party submitting the form must attest to taxpayer identity authentication 9.
• Form 2848: For remote e-signatures, the submitter must authenticate both the signer’s identity and, for entities, the signer’s authority/relationship, using steps such as verifying government photo ID and entity details, unless the submitter has personal knowledge from an established relationship 10.
• Section 6103(c) disclosures can use electronic taxpayer consent; IRS regulations allow consent and certain acknowledgments for e-filed returns and combined Fed/State programs, provided proper consent language and confidentiality protections exist 11.

Withholding certificates and information reporting

Forms W‑8 series electronic signatures

• Electronic W‑8 signatures are permitted if the signature is the final entry, made by the named person, and authenticates and verifies the submission; the perjury statement and instructions must immediately precede the electronic signature. Withholding agents may accept e-signed W‑8s if the form reasonably demonstrates it was electronically signed by the recipient or an authorized signer (e.g., signature block shows signer’s name, timestamp, and electronic signature statement); a typed name alone without other indicators is insufficient 12.
• The same regulation specifies e-sign placement and perjury statement adjacency requirements for electronic W‑8 collection systems 12.

Employer/benefit returns and signatures

Form 8928 and related excise/benefit filings

• Returns, statements, or other documents for excise/benefit taxes under sections 4980B/D/E/G must be signed by the person required to file, or duly authorized signers, as prescribed in applicable forms or instructions. An individual’s signature is prima facie evidence of signing authority 13.
• For ACA AIR filing, there is no “taxpayer electronic signature” requirement for TY2015; however, transmitters must sign portions of the SOAP message with a valid X.509 certificate per AIR specs. Subsequent-year AIR guidance continues to require certificate-based signing at the transmission level 14.

Reporting Agents and other authorizations

Form 8655 (Reporting Agent Authorization)

• IRS allows e-signatures for Form 8655 via specific identity authentication approaches; each retained e-signed form must display evidence of the e-signature and identity/authentication method, and RAs must retain reproducible images and follow submission/record retention rules in Pub. 1474 15.

Consent to use/disclose tax return information

Electronic consents under §7216

• When obtaining taxpayer consent to use or disclose return information electronically, the consent must ensure affirmative, knowing consent of the taxpayer; electronic signatures verifying consent are required. Offshore disclosures have additional safeguards and data protection framework requirements in the same revenue procedure 16.

Practical implementation standards

Authentication, placement, and audit trail

• For returns signed via 8878/8879 families, implement NIST SP 800‑63‑2 Level 2 identity proofing for remote e-signing, capture IP and username for remote sessions, and preserve audit trails and signature images; be prepared to furnish evidence upon IRS request 6.
• For W‑8 electronic signatures, ensure perjury statement immediately precedes the signature, the e-signature is the final entry, and the form reasonably demonstrates it was signed by the identified recipient or authorized person; a typed name alone without other indicators is not sufficient 12.

Program-specific notes and temporary measures

Temporary acceptance of images/digital signatures during COVID

• IRS temporarily allowed images of signatures and digital signatures on certain determination/collection documents and email transmission via secure methods during 2020; these measures were time‑limited and program‑specific. Always confirm current acceptance for your document type 17.

Quick compliance checklist

For individual return e-file (8878/8879)

• Capture signature evidence: signed form image, timestamp, IP and username (remote), identity proofing results, and method/audit trail. Maintain records and furnish on request 6.
• Provide the full return data that will be transmitted when presenting 8879 for e-signature; then transmit after taxpayer authorization 5.

For POA/TIA

• Use IRS e-sign options and, for remote signatures, follow identity/authentication procedures (ID verification, authority verification for entities) before submission 9 10.

For W‑8/W‑9 collection

• Ensure the perjury statement placement and final-entry signature; retain indicators demonstrating the signer’s identity/authority; do not rely on typed name alone 12 12.

If you tell me which document types you need to e-sign (returns, 8879s, W‑8s, 2848/8821, 8655, ACA AIR, etc.), I can give you a tailored step-by-step setup and recordkeeping list.
