IRS E-file Procedures — Mandate, Authorization, Signatures & Rejections

Rule

IRS e-file processes >96% of individual returns and ~81% of corporate returns (FY2024). E-filing is faster and more accurate than paper filing, but the taxpayer remains responsible for accuracy and timely submission.

Preparer E-file Mandate (10-return threshold)

A paid preparer who files 11 or more Form 1040 individual and/or Form 1041 estate/trust returns in a calendar year MUST e-file those returns. The mandate covers only individual, trust, and estate returns — NOT business returns under this preparer rule.

Firm aggregation: All members of a firm are counted together. If the firm files 11+ such returns, every member must e-file all the 1040/1041 returns they prepare — even a member who personally prepares fewer than 11.
Does NOT apply to: unpaid/volunteer preparers (VITA/TCE), individual taxpayers (who may choose paper), fiduciaries acting in a fiduciary capacity (even if paid for fiduciary duties), and preparers of employment-tax returns (Form 940/941/944) or extensions (Form 4868/7004).
Exemptions:
- Foreign preparers without an SSN who cannot get an EFIN (still need PTIN; exempt from mandate)
- Form 8944 (Preparer e-file Hardship Waiver Request) — economic hardship, including being in a Presidentially declared disaster area; approved case-by-case; denied for mere lack of software or personal preference
- Recognized religious groups with conscientious objection to e-filing — NO Form 8944 needed; attach Form 8948 (Preparer Explanation for Not Filing Electronically) to the paper return, checking the religious-objection box

Business/Entity E-file Mandate (10-return threshold, separate rule)

Treasury/IRS final regulations greatly expanded entity e-filing: an entity filing 10 or more total returns/information returns in a year MUST e-file its self-prepared business returns AND information returns. Count ALL applicable returns together (W-2, 1099, 1120, 1065, 990, excise, etc.).

Replaced the old 250-return threshold
Excluded from the count/mandate: employment-tax returns (Form 940, 941, 944) and extension requests (Form 4868, 7004, 8868) — these may still be paper-filed
Applies whether or not the entity uses a paid preparer
Partnerships with >100 partners must also e-file Form 1065 (since 2024)

Applying to E-file — EFIN

To e-file, a preparer needs an Electronic Filing Identification Number (EFIN) by applying to become an Authorized IRS e-file Provider. Process takes ~45 days; no fee.

Step 1: Create an IRS e-Services account (need SSN, address, prior-year AGI)
Identify a principal responsible official and at least one responsible official — each must be a U.S. citizen/lawful permanent resident, 18+, and comply with state/local preparer license/bond rules
Non-credentialed principals/officials must submit fingerprints (Fieldprint® Livescan); attorneys/CPAs/EAs are exempt from fingerprinting
IRS reviews each principal/official (credit check, tax compliance, criminal background)
EFIN is issued per origination location — each fixed location from which an ERO originates electronic submissions needs its own EFIN. A preparation/collection-only location forwarding returns to another origination location may use the owner's fixed-location EFIN. EFIN is non-transferable.
EFIN application must list all return types the provider will transmit (1120, 1065, 990, etc.). Transmitting an unlisted return type will be rejected.

Electronic Return Originator (ERO)

The ERO initiates the e-file transmission to IRS. The ERO may either prepare the return OR accept a self-prepared return from the taxpayer for transmission. ERO duties:

File timely; submit any required paper attachments
Furnish the taxpayer a return copy
Retain records of each filed return and provide them to IRS on request
Enter preparer identifying info (name, address, PTIN)
Watch for and report fraud/abuse; cooperate with IRS investigations
If an ERO only collects (does not prepare) a return but makes a substantial change, the ERO becomes the paid preparer and must sign. "Non-substantial" changes = repositioned entries, typographical, or arithmetic fixes only.

Authorized Transmitter

After the ERO submits, the return goes to an Authorized Transmitter (typically the tax software company — Lacerte, ProSeries, Drake, TaxSlayer, UltraTax, etc.), which transmits to IRS. IRS auto-checks for errors; returns that cannot process are sent back to the originating transmitter.

Electronic Signatures

Two methods let a taxpayer e-sign an individual return using a PIN:

Self-Select PIN — taxpayer provides prior-year AGI or prior-year PIN to verify identity; can be fully paperless if the taxpayer enters their own PIN, OR the ERO enters the PIN after the taxpayer reviews and signs Form 8879.
Practitioner PIN (most common) — taxpayer does NOT need prior-year AGI/PIN; taxpayer must sign the completed Form 8879.

Form 8879 (IRS e-file Signature Authorization): contains taxpayer consent to e-file, declaration the return is true/correct/complete, and the signature method. Retain at least 3 years from the later of the return due date or IRS acceptance date. NOT filed with the return unless IRS asks.

Form 8453 (U.S. Individual Income Tax Transmittal) — used to mail paper attachments/supporting documents needed with an e-filed return; must be mailed within 3 business days of IRS acceptance. If the ERO signs as representative, Form 2848 must be attached.

Identity verification for e-signatures:

In-person: check valid government-issued photo ID, compare photo to person, record name/SSN/address/DOB (credit check optional)
Remote: verify name/SSN/address/DOB/other info against authoritative sources or credit-bureau databases
Remote e-signature does NOT include a handwritten signature on Form 8879 sent by hand/mail/fax/email/website to the ERO

Rejected E-file Returns

ERO must notify the taxpayer within 24 hours of rejection and provide the rejection code and explanation
Perfection period: time to correct and re-transmit (or paper file) without late-filing penalty:
- Individual electronic resubmission: by the fifth calendar day after the return due date when the original electronic submission was timely
- Business returns (1120/1120-S/1065/1041/990): 10 calendar days after IRS rejection notice
- Business extensions (Form 7004) and exempt-org extensions (Form 8868): 5 calendar days
Re-transmission without new signature/authorization allowed if changes are small: gross income/AGI differ by ≤$50; or taxable tax/withholding/refund/balance-due differ by ≤$14.
If a timely submitted individual return cannot be corrected and accepted electronically, a paper return is timely when postmarked by the later of the return due date or 10 calendar days after IRS rejection notification. It must have an original ink signature; the e-file PIN cannot serve as the paper signature.
Paper return filed after a rejected e-file must include: a statement of why it's late, a copy of the rejection notice, a brief history of actions taken to correct, and "Rejected e-file return — (date)" written in red on the top of page 1.

Paper Filing (when allowed/required)

A taxpayer may always choose paper. When a preparer prepares a paper-filed return, attach Form 8948 explaining why it was not e-filed. Paper return requires an original ink signature. Forms that CANNOT be e-filed: Form 706 (estate tax), Form 709 (gift tax), older amended individual returns, fiscal-year individual returns (rare), returns with forms/schedules the e-file system can't process, returns with TINs in 900-00-0000–999-99-9999 range (some ITIN/ATIN excepted), and many nonresident/dual-status alien returns.

E-filed Form W-2 Rules

An e-file provider must NOT e-file a return before receiving ALL of the taxpayer's Forms W-2, W-2G, and 1099-R. Advertising that returns can be filed using only a pay stub/earnings statement is prohibited. If a W-2 cannot be obtained, Form 4852 (Substitute for W-2) may be used — but only as a last resort after trying to get the W-2 from the employer.

E-file Advertising Standards

Approved providers may call themselves an "Authorized IRS e-file Provider" and use the IRS e-file logo
May NOT use the official IRS logo/seal/eagle, the U.S. Treasury seal, or imply any special relationship with IRS
May not combine the e-file logo with the IRS eagle, the word "Federal," or other terms implying an IRS relationship
May not make misleading ads or promise specific refund timeframes
Ads containing fee info (broadcast/TV/internet/print) must be retained for 36 months from last transmission/use

E-file Suspension/Revocation & Penalties

IRS may revoke e-file privileges if a firm/individual is enjoined by court order or barred by federal/state action. Before penalizing, IRS may issue a warning letter specifying corrective action.

Three severity levels: Level 1 (least serious), Level 2, Level 3 (most serious) — there is NO Level 4
Sanctions: written reprimand, suspension, or expulsion from IRS e-file
Suspended providers typically cannot participate for 1–2 years depending on severity
If a principal/responsible official is suspended/expelled, every entity on the firm's e-file application may also be expelled
Suspended/expelled providers may request administrative review within 30 days; the revocation stays in effect during review
IRS may immediately suspend/expel without prior notice (e.g., felony conviction with license revocation)

Protecting the E-file System

Authorized providers must help identify/prevent fraud and abuse, follow mandated security/privacy/business standards, and report security incidents. A provider e-filing individual returns must report an incident to IRS as soon as possible, but no later than the next business day. Reportable incidents: any unauthorized disclosure, misuse, alteration, or destruction of taxpayer information.

Edge Cases

Fiduciary exception: A person who files estate/trust returns (Form 1041) in a fiduciary capacity is NOT a "preparer" and is exempt from the e-file mandate — even if paid for fiduciary services.
ERO who makes a substantial change becomes the preparer: Correcting math errors or repositioning entries is non-substantial; anything else makes the ERO the signing preparer.
Perfection period is NOT an extension: It only relieves the late-FILING penalty; if tax is owed, payment was still due by the original due date to avoid the late-PAYMENT penalty.
Foreign preparer without SSN: Cannot get an EFIN and is exempt from the e-file mandate — but still must have a PTIN and put preparer info on the return.
EFIN is per location, PTIN is per person: All preparers in one office share one EFIN; each preparer uses their own PTIN. Selling a business does not transfer the EFIN.

Common Traps

11 returns, not 10: The preparer mandate triggers at 11 or more Form 1040/1041 returns. Business returns and employment-tax returns do NOT count toward this preparer threshold.
24-hour notification rule: ERO must notify the taxpayer of a rejection within 24 hours. Candidates often pick 48 or 72 hours.
Individual perfection timing: A timely rejected individual e-file must be electronically resubmitted by the fifth calendar day after the return due date. Individual paper fallback uses the later of the due date or 10 calendar days after rejection notification. Business MeF periods are separately governed by Publication 4163.
Cannot advertise "pay stub only" filing: Promoting early filing using only a final pay stub is prohibited and can get a provider expelled from e-file. Form 4852 is the only permitted substitute, and only as a last resort.
EFIN vs. PTIN vs. EFIN transfer: EFIN cannot be sold/transferred with a business; each fixed location originating electronic submissions needs its own, while collection-only locations may use the owner's origination-location EFIN. PTIN is personal and non-transferable.
Religious objection needs Form 8948, not 8944: Conscientious objectors in recognized religious groups are automatically exempt — they attach Form 8948 (not a waiver request) to the paper return.
No Level 4 violation: Severity levels run 1 (least) to 3 (most). A "Level 4" answer is always wrong.
Identity verification for remote e-signatures does NOT accept a handwritten Form 8879 sent by mail/fax/email — it requires database/credit-bureau verification.
