IRS Electronic Signature (e-Signature) Program - Complete Guide 2024

The IRS Electronic Signature (e-Signature) Program establishes the policies, procedures, and requirements for accepting taxpayer signatures in electronic form. This comprehensive guide covers everything you need to know about signing tax documents electronically in compliance with IRS regulations.

What is an Electronic Signature?

According to the IRS, an electronic signature is an electronic sound, symbol, or process attached to or logically associated with an electronic record and executed or adopted by a person with the intent to sign the electronic record.

Electronic signatures are not the same as:

• Scanned/Faxed Signatures - Images of handwritten signatures sent via fax
• Internal IRS Documents - This program applies only to taxpayer-facing documents
• Unverified Digital Images - Simply typing your name without authentication doesn't qualify

Legal Authority

The IRS e-Signature program is based on several federal laws and regulations:

• IRC 6061 - Directs the Secretary of Treasury to "develop procedures for the acceptance of signatures in digital or other electronic form"
• E-SIGN Act (2000) - Federal law giving electronic signatures the same legal status as handwritten signatures
• GPEA (Government Paperwork Elimination Act) - Mandates federal agencies accept electronic documents and signatures
• NIST SP 800-63 - Digital Identity Guidelines for authentication and identity assurance
• UETA (Uniform Electronic Transactions Act) - Adopted by most states to validate electronic signatures

Five Requirements for Legally Binding Electronic Signatures

For an electronic signature to be legally binding and acceptable to the IRS, it must meet all five of these requirements:

1. Intent to Sign the Electronic Record

The signer must demonstrate clear intent to sign the document. This can be shown through:

• Clicking an "I agree" or "Submit" button
• Typing your name in a signature field
• Using a stylus or finger to draw your signature on a touchscreen
• Checking a box that says "I certify under penalties of perjury..."
• Using a Personal Identification Number (PIN)

2. Attachment or Association with the Electronic Record

The signature must be:

• Embedded in the electronic document, or
• Logically associated with it in a way that can be verified

Examples include:

• A digital signature certificate embedded in a PDF
• A signature field value stored in a database linked to the document
• Cryptographic binding between signature and document

3. Identity and Authentication of the Signer

The IRS must be able to verify the signer's identity. Acceptable authentication methods include:

• Knowledge-based authentication - Answering personal questions based on credit bureau data
• Multi-factor authentication - Password + SMS code, or password + authenticator app
• Digital certificates - PKI (Public Key Infrastructure) certificates
• IRS.gov account authentication - Using verified IRS online accounts
• Self-Select PIN - For e-filed returns (combined with AGI from prior year)

4. Preserving the Integrity of the Signed Electronic Record

Once signed, the document must be protected against alteration. Methods include:

• Digital signatures with hash algorithms - Any change invalidates the signature
• Audit trails - Logging all access and changes to the document
• Version control - Maintaining signed versions separately from drafts
• PDF/A archival format - Long-term preservation standard

5. Secure Storage

Electronic records with e-signatures must be stored securely and:

• Maintained for the required retention period (usually 3-7 years for tax records)
• Protected against unauthorized access
• Retrievable when needed
• Preserved in a format that maintains the signature's integrity

Acceptable Forms of Electronic Signatures

Signature Type	Description	Example Use
Self-Select PIN	5-digit PIN chosen by taxpayer for e-filing	E-filed individual tax returns
Digital Signature	Cryptographic signature using PKI certificates	Business returns, practitioner signatures
Typed Name	Typing full name in signature field (with authentication)	Online forms with account login
Stylus/Touchscreen	Drawing signature on device screen	In-person appointments with tablets
Click-to-Sign	Clicking "I agree" or "Submit" button	Web applications and forms
Checkbox with Attestation	Checking box next to perjury statement	Online applications and requests

Tax Forms That Accept Electronic Signatures

Acceptable Deviations and Special Cases

Images of Signatures (Limited Use)

In certain taxpayer interactions, the IRS may accept:

• Scanned signatures - Image of handwritten signature on uploaded documents
• Faxed signatures - Signatures sent via Enterprise Electronic Fax (EEFax)
• Photo signatures - High-quality photos of signed documents

Note: These are considered "images" of signatures, not true electronic signatures, and are only acceptable in specific circumstances defined by the business unit.

Provisional Signatures

Some forms allow provisional electronic signatures that are verified later:

• Form 3911 - Taxpayer Statement Regarding Refund
• Emergency situations where immediate action is required

Authentication Requirements

The level of authentication required depends on the risk level of the transaction:

Low-Risk Transactions

• Requesting tax transcripts
• Making payments
• Single-factor authentication acceptable

Medium-Risk Transactions

• Filing tax returns
• Updating account information
• Two-factor authentication recommended

High-Risk Transactions

• Power of Attorney (Form 2848)
• Identity verification for fraud cases
• Strong multi-factor authentication required
• May require knowledge-based authentication

E-File Self-Select PIN Method

The most common electronic signature method for individual taxpayers:

How It Works:

1. Choose a 5-digit PIN (any numbers except all zeros)
2. Enter your prior year Adjusted Gross Income (AGI) for verification
3. Provide your date of birth
4. Electronically sign your return with the PIN

Security Features:

• PIN is known only to the taxpayer
• Prior year AGI verification proves you filed previously
• Birth date adds additional identity confirmation
• Cryptographically bound to your return

Practitioner Electronic Signatures

Tax professionals can sign client returns electronically using:

Practitioner PIN (PPIN)

• 6-digit self-selected PIN
• Requires Preparer Tax Identification Number (PTIN)
• Used for signing returns as paid preparer

Digital Certificates

• PKI-based digital signatures
• Higher assurance level
• Required for some business and international returns

Compliance and Record Retention

What You Must Keep:

• The signed electronic record - Complete copy of what was signed
• Authentication logs - Evidence of identity verification
• Audit trail - Who accessed, when, and what actions were taken
• Signature metadata - Timestamp, IP address, method used

How Long to Keep Records:

• Minimum 3 years - General tax record retention
• 6 years - If you underreported income by more than 25%
• 7 years - For bad debt deductions or worthless securities
• Indefinitely - For property records, fraudulent returns, or unfiled returns

Common E-Signature Mistakes to Avoid

Benefits of Electronic Signatures
