Yes, the Internal Revenue Service accepts scanned signatures on a wide and growing list of tax forms, and it also accepts digital signatures, electronic signatures, and photographed ink signatures on many of the same documents. The IRS made this flexibility permanent on October 17, 2023, when it updated the Internal Revenue Manual 10.10.1 to codify pandemic-era allowances that had been set to expire, giving taxpayers and tax professionals long-term certainty.
The core problem is simple. Internal Revenue Code §6061 requires every return, statement, or other document to be signed under rules the Secretary prescribes, and historically that meant a wet-ink signature on paper. When wet-ink was impossible during COVID-19, the IRS issued Memorandum NHQ-10-1121-0005 and successor memos allowing scanned and digital signatures, but those flexibilities had rolling sunset dates that created compliance confusion. The consequence of getting it wrong is severe: an unsigned or improperly signed return is treated as not filed, which can trigger failure-to-file penalties under IRC §6651, blown statute-of-limitations arguments, and rejected power-of-attorney submissions.
According to the IRS Fiscal Year 2024 Data Book, the IRS processed more than 266 million returns and forms in FY 2024, and over 213 million were filed electronically, meaning roughly 80% of all taxpayer interactions already rely on some form of non-wet-ink signature technology.

The Legal Foundation for IRS Signature Rules
Signature law for federal taxes starts with IRC §6061(a), which states that any return, statement, or other document required under the internal revenue laws must be signed in accordance with forms or regulations prescribed by the Secretary of the Treasury. The plain-English meaning is that the IRS decides what counts as a valid signature, and the agency has broad authority to accept or reject signature formats. The consequence of filing a return without a valid signature is that the document is treated as a nullity, so the filing clock never starts, and penalties continue to accrue as if the return were never submitted.
A common misconception is that any mark on the signature line is legally binding. In Elliott v. Commissioner, 113 T.C. 125 (1999), the Tax Court held that an unsigned return does not start the statute of limitations on assessment, which means the IRS can audit that year forever. That ruling still controls today, and it applies equally to scanned signatures that are missing, illegible, or placed on the wrong line.
Congress expanded electronic filing authority in IRC §6061(b), which authorizes the Secretary to develop procedures for alternative signature methods. Treasury then issued Treas. Reg. §1.6061-1, which allows the Commissioner to prescribe any signature method that identifies and authenticates the signer. The consequence of this delegation is that the IRS can approve new technologies, like DocuSign or Adobe Sign, without waiting for Congress to pass a new statute.
The Electronic Signatures in Global and National Commerce Act (ESIGN Act, 15 U.S.C. §7001) gives electronic signatures the same legal weight as handwritten signatures in most commercial settings. However, ESIGN carves out certain government filings, so the IRS is not automatically bound by it. The real-world example is that a bank can accept a DocuSign on a mortgage under ESIGN, but the IRS only accepts DocuSign on forms it has specifically approved in the IRM.
IRM 10.10.1 and the 2023 Permanent Rules
The controlling internal guidance is IRM 10.10.1, IRS Electronic Signature (e-Signature) Program, which the IRS rewrote on October 17, 2023 to make pandemic-era scanned and digital signature allowances permanent. The plain-English explanation is that the IRM is the IRS’s own rulebook, and employees must follow it when processing taxpayer submissions. The consequence of an IRS employee ignoring IRM 10.10.1 is that the taxpayer can escalate through the Taxpayer Advocate Service or raise the violation in Tax Court.
A real-world example is Martinez CPA Group, a three-partner firm in Austin, Texas. Before October 2023, the firm scanned every Form 2848 and hoped the temporary memos would be extended. After the IRM update, the firm now relies on the permanent rule, which eliminates the annual anxiety of watching for sunset dates. A common misconception is that the 2023 update allows every form to be signed electronically, but the IRM still contains a specific list of covered forms.
The COVID-19 Signature Memoranda Timeline
The IRS first allowed broad use of scanned and digital signatures in Memorandum NHQ-10-0820-0001, issued August 28, 2020, which was then extended by a series of follow-up memos including NHQ-10-1121-0005 in November 2021. The plain-English explanation is that each memo pushed the expiration date forward by six to twelve months while the IRS studied whether to make the rule permanent. The consequence of relying on an expired memo is that the IRS processing center may reject the filing, which happened frequently in late 2023 as the rules shifted.
A common misconception is that the temporary memos are still the governing authority. They are not. The permanent rule now lives in IRM 10.10.1, and the memos have been formally superseded.
What Counts as a Scanned Signature
A scanned signature is an image of a handwritten, wet-ink signature that has been captured by a scanner, camera, or smartphone and then attached to a digital document. The IRS defines it in IRM 10.10.1.3.2 as an image of a signature, distinct from a typed name, a digital certificate, or a third-party e-signature platform output. The consequence of confusing these categories is that the IRS may accept one format but not another on the same form, so practitioners must match the format to the form.
The real-world example is Priya Shah, a sole proprietor in Dayton, Ohio. Priya prints Form 2848, signs it with a blue pen, snaps a photo with her iPhone, and emails the image to her CPA. That photographed signature qualifies as a scanned signature under IRM 10.10.1, and the CPA may upload it through the Tax Pro Account without any additional authentication.
Scanned vs. Digital vs. Electronic Signatures
The three signature categories are often used interchangeably in casual conversation, but the IRS treats them as legally distinct. The plain-English explanation is that a scanned signature is a picture of a pen stroke, a digital signature uses cryptographic keys to verify identity, and an electronic signature is a typed name, checkbox, or mouse-drawn mark captured by a software platform. The consequence of mislabeling a signature is that the wrong authentication trail may be attached to the filing, which can cause processing delays.
| Signature Type | IRS Definition and Use |
|---|---|
| Scanned signature | Image of a wet-ink signature captured by scanner or camera, accepted on listed forms per IRM 10.10.1 |
| Digital signature | Cryptographically secured signature using PKI, accepted through IRS-approved providers |
| Electronic signature | Typed name, mouse mark, or click-to-sign on an IRS-approved platform such as the e-file signature PIN |
A common misconception is that any DocuSign envelope satisfies every IRS form. It does not. DocuSign must use the IRS-compliant workflow with knowledge-based authentication (KBA) for certain forms like Form 8879.
Which Forms Accept Scanned Signatures
The permanent rule in IRM 10.10.1.3.2.1 lists the forms that the IRS will accept with a scanned or digital signature. The plain-English explanation is that if your form is on the list, you can sign it in ink, scan it, and submit it by fax, mail, or the Document Upload Tool. The consequence of submitting a scanned signature on a form not on the list is that the IRS will reject the filing and send a correspondence notice requiring a wet-ink original.
The Permanent List Under IRM 10.10.1
The covered forms include Form 706 (Estate Tax Return), Form 709 (Gift Tax Return), Form 1066 (REMIC Income Tax Return), Form 1120-C (Cooperative Association Return), Form 1120-H (Homeowners Association Return), Form 2848 (Power of Attorney), Form 8821 (Tax Information Authorization), Form 8832 (Entity Classification Election), and Form 3115 (Application for Change in Accounting Method). The plain-English explanation is that these forms typically cannot be e-filed through the regular MeF pipeline, so the IRS allows imaged signatures to avoid forcing paper-only processing.
A real-world example is Kenji Watanabe, an estate executor in Honolulu, Hawaii. Kenji signs Form 706 with a blue pen, scans it to PDF, and mails the paper copy while emailing the PDF to the IRS estate tax specialist assigned to the case. Both copies carry legal weight under IRM 10.10.1.
The Non-Permanent List and Form 1040 Nuances
Form 1040 is not on the scanned signature list because it flows through the e-file system, which uses a Self-Select PIN or Practitioner PIN instead of a scanned image. The plain-English explanation is that when a form can be e-filed, the IRS prefers the PIN-based authentication built into MeF. The consequence of scanning a 1040 signature and mailing it is that the return will still be accepted because paper 1040s with wet-ink originals are valid, but a scanned image on a mailed paper return can trigger a manual review.
A common misconception is that Form 1040-X (Amended Return) follows the same rule. In fact, the IRS allows amended 1040-X returns to be e-filed using the same PIN framework, and scanned signatures are not separately listed for paper 1040-X filings. An expansion example is Linda Okafor, a taxpayer in Newark, New Jersey, who amends her 2024 return in 2026. Linda e-files Form 1040-X through her tax software and uses the Self-Select PIN instead of worrying about scanning.
Three Common Scenarios
Real-world scenarios illustrate how the rules work in practice. The plain-English explanation is that most taxpayers will fall into one of three buckets: practitioner-submitted authorizations, taxpayer-submitted estate or gift returns, and entity elections.
Scenario Table 1: Practitioner Power of Attorney
| Practitioner Action | IRS Processing Outcome |
|---|---|
| CPA scans Form 2848 signed in ink by client and uploads through Tax Pro Account | IRS processes within 5 business days under IRM 10.10.1 |
| CPA types client’s name on Form 2848 signature line without authorization | IRS rejects as unauthorized practice under Circular 230 §10.51 |
Scenario Table 2: Estate Tax Return
| Executor Action | IRS Processing Outcome |
|---|---|
| Executor signs Form 706 in ink, scans to PDF, mails paper copy | IRS accepts under permanent scanned signature rule |
| Executor uses DocuSign without KBA on Form 706 | IRS rejects because 706 requires scanned image of wet-ink, not e-signature |
Scenario Table 3: Entity Election
| Business Action | IRS Processing Outcome |
|---|---|
| LLC member scans Form 8832 with ink signature, faxes to IRS service center | IRS processes election effective on chosen date |
| LLC member submits typed name on Form 8832 | IRS rejects, election date may be lost per Rev. Proc. 2009-41 |
Named Examples of Scanned Signature Use
Concrete examples make the rules easier to apply. The plain-English explanation is that the IRS evaluates each signature against the IRM and the form instructions, and named scenarios help practitioners spot the pattern.
Example 1: Maria Gonzalez and Form 2848
Maria Gonzalez is a retired teacher in Phoenix, Arizona, who receives a CP2000 notice proposing $4,800 in additional tax. Maria hires an enrolled agent named David Chen, signs Form 2848 in ink, and scans it to PDF. David uploads the PDF through the Tax Pro Account, and the IRS processes the authorization in four business days. The consequence of Maria using a typed name instead of a scanned ink signature would have been an immediate rejection and a delay of several weeks in responding to the CP2000.
Example 2: Robert Nguyen and Form 706
Robert Nguyen serves as the executor for his late mother’s estate in Seattle, Washington. The estate is valued at $14.2 million, which exceeds the 2026 federal estate tax exemption and requires Form 706. Robert signs the return in blue ink, scans it to PDF, and emails the PDF to the IRS estate tax examiner while also mailing the paper original. The scanned image satisfies the permanent IRM rule, and the examiner begins reviewing the return without waiting for the mailed copy.
Example 3: Aisha Patel and Form 8832
Aisha Patel forms a single-member LLC in Atlanta, Georgia, and wants her LLC taxed as a C-corporation starting January 1, 2026. She completes Form 8832, signs it in ink on December 20, 2025, and faxes the scanned image to the Cincinnati service center. The IRS accepts the election with the effective date she chose. A common misconception is that typed names work on Form 8832 because the form is a simple election. They do not, and the consequence of a typed name is that the election is treated as never made, which can cost the business thousands in unexpected self-employment tax.
Mistakes to Avoid
Errors with scanned signatures can cost time, money, and legal protections. The plain-English explanation is that even small formatting mistakes can cause rejection under IRM 10.10.1.
- Typing a name instead of scanning an ink signature. The IRS rejects typed names on forms that require a scanned image, and the consequence is a lost filing date under Elliott v. Commissioner.
- Using a signature on a form not listed in IRM 10.10.1. Forms such as Form 1040-ES vouchers do not require any signature, and confusion about which forms need what can cause unnecessary filings.
- Submitting a low-resolution scan. The IRS may reject an illegible scan, and the consequence is that the return is treated as unsigned, triggering failure-to-file penalties.
- Missing the date field next to the signature. Form 2848 Instructions require the signature date, and a missing date causes rejection because the authorization window cannot be calculated.
- Using an expired memorandum as authority. The COVID memos are no longer controlling, and citing them to an IRS employee may cause confusion.
- Applying DocuSign without KBA on Form 8879. Form 8879 (IRS e-file Signature Authorization) requires knowledge-based authentication for remote electronic signatures per Publication 1345.
- Forgetting spousal signatures on joint returns. A joint return without both spouses’ signatures is treated as not filed for the non-signing spouse, destroying joint filing benefits.
- Scanning only page one of a multi-page form. The IRS requires the entire form, and a missing page can cause rejection.
- Relying on state rules for federal filings. Some states accept typed names; the IRS does not on listed forms.
Do’s and Don’ts
Signature compliance is easier with a clear checklist. The plain-English explanation is that doing a few things right prevents most rejections.
- Do sign in blue or black ink before scanning, because it makes the image clearly distinguishable from a photocopy.
- Do save the scan as a 300 DPI PDF, because the IRS prefers crisp images that can be read during processing.
- Do verify the form is listed in IRM 10.10.1 before relying on a scanned signature.
- Do keep the wet-ink original for at least three years, in case the IRS requests verification.
- Do use the Document Upload Tool when available, because it creates a timestamped receipt.
- Don’t use a stamp or autopen unless the taxpayer has an authorized signature procedure under Rev. Rul. 68-500.
- Don’t email a scanned Form 2848 to a general IRS email address, because the IRS does not accept general email submissions.
- Don’t assume your state tax agency follows the same rules; California, New York, and Illinois each have separate e-signature standards.
- Don’t use a cropped image that cuts off any part of the signature line.
- Don’t forget the signer’s title (e.g., Trustee, Executor, Member) when signing in a representative capacity.
Pros and Cons of Scanned Signatures
Weighing the trade-offs helps taxpayers choose the right format. The plain-English explanation is that scanned signatures save time but require extra care.
- Pro: Faster submission than mailing a wet-ink original, especially for executors and practitioners with tight deadlines.
- Pro: Permanent rule under IRM 10.10.1 eliminates sunset-date anxiety that plagued 2020-2023 filings.
- Pro: Works with the Document Upload Tool for real-time delivery confirmation.
- Pro: Accepted on high-stakes forms like Form 706 where e-file is not available.
- Pro: Reduces paper storage costs for large practitioner firms.
- Con: Not accepted on every IRS form, so practitioners must check IRM 10.10.1 each time.
- Con: Low-quality scans can cause rejection and force re-filing.
- Con: Does not eliminate the need for a wet-ink original in audit defense situations.
- Con: States do not uniformly follow the federal rule, creating multi-jurisdiction complexity.
- Con: Requires stronger internal controls to prevent forgery, because a scanned image is easier to replicate than a wet-ink signature.
How the Document Upload Tool Works
The IRS Document Upload Tool is the agency’s primary channel for submitting scanned signed documents in 2026. The plain-English explanation is that taxpayers receive an access code on an IRS notice, log in, and upload the signed PDF directly to the assigned IRS unit. The consequence of not using the tool when available is that mailed correspondence can take 8-12 weeks longer to reach the correct processor.
A real-world example is Samuel Reyes, a small business owner in Miami, Florida, who receives a Letter 6419 requesting additional documentation. Samuel scans his signed response, uploads it through the tool, and receives a confirmation number the same day. A common misconception is that the tool accepts any form; it only accepts documents tied to a specific open IRS case referenced in a notice.
State Nuances and Federal Interaction
Although federal law controls IRS filings, state rules can affect the same transaction. The plain-English explanation is that a taxpayer signing a federal Form 2848 for the IRS may also need a separate state power of attorney using the state’s own signature rules.
The California Franchise Tax Board Form 3520-PIT accepts scanned signatures but requires a separate declaration, while the New York Department of Taxation and Finance Form POA-1 accepts electronic signatures only through the state’s Online Services portal. The consequence of using a federal 2848 for a state matter is that the state agency will reject it because the authorization does not cover state tax matters. A common misconception is that a signed federal Form 2848 authorizes the practitioner for state audits. It does not, and the practitioner must file the state-specific authorization separately.
Key Entities and Their Roles
Understanding who is involved clarifies the signature process. The plain-English explanation is that multiple parties share responsibility for valid signatures, and each has a different legal role.
- The Commissioner of Internal Revenue sets signature policy under delegated Treasury authority.
- The Office of Chief Counsel issues legal memoranda interpreting §6061.
- The Taxpayer Advocate Service helps taxpayers when an IRS employee ignores IRM 10.10.1.
- Circular 230 practitioners (attorneys, CPAs, enrolled agents) may sign Form 2848 for limited purposes.
- Authorized IRS e-file Providers handle electronic signature authentication for 1040s.
Recap of Relevant Rulings and Guidance
Court decisions and IRS rulings shape signature practice. The plain-English explanation is that the rules have evolved through litigation and administrative guidance, not just regulations.
Elliott v. Commissioner, 113 T.C. 125 (1999) holds that an unsigned return does not trigger the statute of limitations. Dingman v. Commissioner, T.C. Memo 2011-116 extends the principle to returns signed by someone without legal authority. Rev. Rul. 68-500 authorizes autopen and facsimile signatures only when the taxpayer has established an internal authorization procedure. Chief Counsel Advice 201927014 confirmed that electronic signatures from third-party platforms are valid when they meet the identify and authenticate standard of Treas. Reg. §1.6061-1.
FAQs
Does the IRS accept scanned signatures on Form 1040?
No. Paper Form 1040 requires a wet-ink original signature; e-filed 1040 returns use a Self-Select or Practitioner PIN rather than a scanned image under IRS e-file signature rules.
Are scanned signatures permanent under IRS rules?
Yes. The IRS made scanned and digital signatures permanent on October 17, 2023, through the revised IRM 10.10.1, replacing the temporary COVID-era memoranda.
Can I scan a signature on Form 2848?
Yes. Form 2848 is explicitly listed in IRM 10.10.1, so you can sign in ink, scan the form, and submit via the Tax Pro Account or by fax.
Does the IRS accept DocuSign signatures?
Yes. The IRS accepts DocuSign on approved forms when it meets the identity authentication standard, but DocuSign is not valid on every form, so check IRM 10.10.1 first.
Can a spouse scan a signature on a joint return?
No. Paper joint 1040s require wet-ink originals from both spouses; a joint return with a scanned signature may be processed but can be challenged as unsigned on audit.
Does the IRS accept photographed signatures from a phone?
Yes. A clear smartphone photo of a wet-ink signature qualifies as a scanned image under IRM 10.10.1 if the form is on the approved list and the image is legible.
Can I use an autopen on IRS forms?
Yes. Rev. Rul. 68-500 permits autopen signatures when the taxpayer has an internal written authorization procedure, though most individual taxpayers will not meet this bar.
Are typed names accepted as signatures?
No. A typed name on a signature line is not a valid signature on forms requiring scanned or wet-ink signatures, and the consequence is rejection under Elliott v. Commissioner.
Does the IRS accept scanned signatures on Form 8879?
Yes. Form 8879 allows electronic signatures with knowledge-based authentication per Publication 1345, and scanned ink signatures are also accepted.
Can I email a scanned signed form to the IRS?
No. The IRS does not accept general email submissions; use the Document Upload Tool, fax, or mail instead.
Does the IRS accept scanned signatures on amended returns?
Yes. Form 1040-X can be e-filed with PIN authentication, and paper 1040-X with a wet-ink or legible scanned ink signature is also accepted under current processing rules.
Are scanned signatures valid on Form 706 estate returns?
Yes. Form 706 is on the permanent IRM 10.10.1 list, so an executor may sign in ink, scan the document, and submit both paper and digital copies.
