Definition of Electronic Return Originator (ERO)
An Electronic Return Originator (ERO) is an authorized IRS e-file provider that originates the electronic submission of tax returns. This role is distinct from a transmitter or an intermediate service provider. The ERO is the first point of contact for the taxpayer and is responsible for the integrity of the data submitted to the Internal Revenue Service.
Operation as an ERO requires federal authorization and adherence to strict regulatory standards. Business owners must distinguish between preparing a return and originating the electronic file. Those who prepare returns but do not possess an Electronic Filing Identification Number (EFIN) must work through a provider that offers ERO services.
IRS E-file Application Process
To operate as an ERO, a tax professional must complete the IRS e-file Application. This process is handled through the IRS e-services portal.
Technical Requirements for Application:
- Create an e-services Account: Requires identity verification through the IRS-approved credential service.
- Submit Application: Select the "ERO" role within the application.
- Suitability Check: The IRS performs a background check, including a credit check and a criminal history check.
- Fingerprinting: Applicants must provide fingerprints unless they are a licensed professional (CPA, Enrolled Agent, or Attorney) in good standing.
The approval process can take up to 45 days. Once approved, the IRS issues an EFIN. This number is mandatory for any business transmitting more than 10 tax returns per year.

IRS Publication 1345 Compliance
IRS Publication 1345, Handbook for Authorized IRS e-file Providers of Individual Income Tax Returns, is the primary regulatory document for ERO operations.
Data Transmission Standards
EROs must ensure that the electronic return data is transmitted accurately. If an ERO does not transmit directly to the IRS, they must use an authorized transmitter. All data must be encrypted during transmission to prevent unauthorized access.
Form 8879: IRS e-file Signature Authorization
The ERO must obtain a signed Form 8879 from the taxpayer before the return is transmitted. This document authorizes the ERO to file the return electronically.
- Retention: EROs must keep Form 8879 and all supporting documents (W-2s, 1099s) for three years.
- Verification: EROs are responsible for verifying the identity of the taxpayer. This includes checking government-issued photo identification.
Infrastructure and Professional Software
Scaling a tax business requires high-capacity infrastructure. EROs must select software that supports direct transmission and integrates with bank products for refund processing.
Software Selection
Professional software is categorized into desktop installations and Software as a Service (SaaS).
- Essential Tax Software: Designed for small to medium firms requiring reliable cloud access. View Essential Tax Software.
- Unlimited Tax Software: Necessary for high-volume EROs managing multiple offices or sub-offices. View Unlimited Tax Software.
Hardware Requirements
Efficient operations require:
- High-speed document scanners for paperless document retention.
- Encrypted local storage or secure cloud servers.
- Multi-factor authentication (MFA) on all devices accessing tax data.

Security and the WISP Requirement
EROs are subject to the FTC Safeguards Rule. This requires the implementation of a Written Information Security Plan (WISP). Failure to maintain a WISP can lead to IRS sanctions and EFIN suspension.
Components of a WISP:
- Designated Coordinator: One individual must be responsible for the security program.
- Risk Assessment: Identification of internal and external risks to taxpayer data.
- Safeguard Implementation: Firewalls, anti-virus software, and data encryption.
- Service Provider Oversight: Ensuring that third-party vendors (like software providers) maintain high security standards.
The TIG Tax Pros infrastructure provides built-in security features that assist EROs in maintaining compliance with federal data privacy laws.
State-Specific Operations: Ohio Compliance
While federal ERO status is primary, state-level requirements vary. For operations in Ohio, EROs must be aware of specific state filing mandates.
Ohio Department of Taxation Requirements
Ohio requires practitioners to file electronically if they prepare more than 11 returns per year. EROs must ensure their software is updated with the latest Ohio Department of Taxation schemas.
- Ohio Form IT 1040: Must be filed using the same EFIN used for federal returns.
- Local/Municipal Filings: Some Ohio municipalities require separate filings (e.g., RITA or CCA). EROs must determine if their software supports these specific local integrations.
Staying updated on state-specific changes is critical. For current updates on tax law changes across different jurisdictions, visit our Updates Category.

Service Bureau Onboarding
Large-scale EROs often transition into a Service Bureau model. In this capacity, the ERO provides software and support to other tax preparers (sub-offices).
Responsibilities of a Service Bureau:
- Software Provisioning: Licensing SaaS products to smaller firms.
- EFIN Management: Verifying the EFIN status of all sub-offices.
- Support: Providing technical and tax law support to the network.
Becoming a Service Bureau allows for revenue growth through software overrides and administrative fees. Information on joining the network can be found at Become a TIG Tax Pro.
Audit Protection and Due Diligence
EROs face significant liability for the accuracy of the returns they originate. IRC Section 6695(g) details the due diligence requirements for specific credits (EITC, CTC, ODC, AOTC, and Head of Household filing status).
Due Diligence Checklist:
- Form 8867: Must be completed and submitted with every return claiming the specified credits.
- Knowledge Requirement: The ERO must not ignore information that a reasonable person would find incorrect or incomplete.
- Record Retention: EROs must retain copies of any documents provided by the taxpayer that were used to determine eligibility for credits.
Integrating audit protection services into your ERO operations provides a layer of security for both the business owner and the client.

Managing EFIN Security
The EFIN is a valuable asset. The IRS monitors EFIN usage patterns to detect fraud.
Best Practices for EFIN Security:
- Monitor EFIN Activity: Regularly check the e-file application on e-services to verify the number of returns transmitted under your EFIN matches your records.
- Limit Access: Only authorized employees should have access to software containing the EFIN.
- Reporting: If an EFIN is compromised, notify the IRS e-help desk immediately.

Financial Operations for EROs
EROs must manage bank product integration to offer "No Out of Pocket" filing to clients. This involves partnering with a tax-focused bank (such as Santa Barbara TPG, Republic Bank, or Refundo).
Bank Product Workflow:
- Software Integration: Link the EFIN to the preferred bank within the tax software.
- Fee Setup: Set prep fees and electronic filing fees.
- Disbursement: Fees are deducted from the taxpayer's refund and deposited into the ERO's business account via the bank partner.
