Electronic Return Originators (EROs) face increased scrutiny from the Internal Revenue Service (IRS) and state tax authorities in 2026. As the digital landscape for tax preparation evolves, the responsibility of the ERO to maintain high standards of integrity and accuracy becomes a critical business function. Audit protection for an ERO is not merely about defending individual returns; it is about establishing a systemic framework that protects the ERO’s Electronic Filing Identification Number (EFIN) and the viability of the tax business.
Defining ERO Audit Protection in 2026
For a tax professional, audit protection refers to the proactive measures and reactive protocols implemented to ensure compliance with IRS Publication 1345, "Handbook for Authorized IRS e-file Providers of Individual Income Tax Returns."
While consumer-facing audit protection services focus on representing taxpayers during an examination, ERO-centric audit protection focuses on:
- Maintaining rigorous due diligence records.
- Securing taxpayer data against unauthorized access.
- Verifying the identity of taxpayers to prevent fraud.
- Ensuring the accuracy of electronic submissions to minimize IRS error triggers.
Failure to implement these protections can result in the suspension of e-filing privileges, significant monetary penalties under Internal Revenue Code (IRC) Section 6695(g), and legal liability.
IRS Due Diligence and IRC Section 6695(g)
The IRS continues to prioritize due diligence for specific tax credits. In 2026, the penalties for failing to meet due diligence requirements have increased. EROs must adhere to the standards set for the Earned Income Tax Credit (EITC), Child Tax Credit (CTC), Additional Child Tax Credit (ACTC), Credit for Other Dependents (ODC), American Opportunity Tax Credit (AOTC), and the Head of Household (HOH) filing status.
Form 8867 Requirements
EROs must complete Form 8867, "Paid Preparer’s Due Diligence Checklist," for every return involving these credits. The form must be based on information provided by the taxpayer or information the preparer reasonably believes to be true.
Record Retention
Under Section 6695(g), EROs must retain:
- A copy of Form 8867.
- The applicable due diligence worksheets.
- A record of how and when the information used to determine the credits and filing status was obtained.
- Copies of any documents provided by the taxpayer that the preparer relied on to determine eligibility.
Records must be kept for three years from the latest of the return's due date (excluding extensions) or the date the return was filed.
Publication 1345 Compliance Standards
IRS Publication 1345 dictates the operational requirements for EROs. Compliance in 2026 requires strict adherence to the following:
Identity Verification
EROs must verify the identity of taxpayers, spouses, and dependents. In an environment with heightened identity theft, the IRS expects EROs to inspect valid government-issued photo identification. For remote clients, EROs should utilize multi-factor authentication (MFA) and secure portals that comply with National Institute of Standards and Technology (NIST) guidelines.
Safeguarding the EFIN
Your EFIN is the most valuable asset of your tax business. Unauthorized use of an EFIN can lead to immediate suspension. EROs should:
- Monitor their EFIN status via the IRS e-services portal at least once a week during peak season.
- Ensure the number of returns filed matches internal records.
- Update the IRS e-file application within 30 days of any changes to business structure, address, or key personnel.
Data Security and the FTC Safeguards Rule
The Federal Trade Commission (FTC) Safeguards Rule requires non-banking financial institutions, including tax preparers, to develop, implement, and maintain a comprehensive information security program.
Written Information Security Plan (WISP)
Every ERO must have a Written Information Security Plan (WISP). A compliant WISP for 2026 must include:
- Designation of a qualified individual to oversee the security program.
- A written risk assessment identifying internal and external threats to taxpayer data.
- Implementation of safeguards to control identified risks (e.g., encryption of data at rest and in transit).
- Regular testing and monitoring of the effectiveness of these safeguards.
- A plan for responding to security incidents and data breaches.
State-Specific Compliance: Ohio ERO Requirements
For EROs operating in Ohio, the Ohio Department of Taxation (ODT) maintains specific standards that complement federal requirements. As of April 2026, Ohio EROs must ensure they are in good standing with the state’s electronic filing program.
Ohio E-file Registration
Ohio generally follows the federal e-file program. However, EROs must be authorized by the IRS to participate in the Ohio program. If the IRS suspends an ERO, Ohio residency and business filing privileges are typically suspended concurrently.
Income Reconciliation for Ohio Returns
The Ohio Department of Taxation utilizes sophisticated data matching to identify discrepancies between federal and state filings. EROs should perform a final reconciliation of 1099-MISC, 1099-NEC, and 1099-K forms against the Ohio IT 1040 and SD 100 to prevent automated state audit flags.

Internal Audit Protocols
Establishing an internal audit process is a primary defense against external IRS examinations. EROs should conduct "desk audits" of their staff’s work throughout the filing season.
Compliance Checkpoints
- Documentation Completeness: Verify that every file contains a signed Form 8879 (IRS e-file Signature Authorization).
- Accuracy Checks: Ensure that data entry matches source documents exactly. In 2026, the IRS uses AI to flag rounded numbers or inconsistent patterns in expense reporting.
- Client Interview Records: Maintain contemporaneous notes of the client interview, especially when clarifying suspicious or inconsistent information provided by the taxpayer.
Utilizing Service Bureaus for Infrastructure
Partnering with a service bureau can provide the technological infrastructure necessary for robust audit protection. Service bureaus often provide:
- Integrated due diligence software modules that prevent return transmission if required forms are incomplete.
- Cloud-based document storage with bank-grade encryption.
- Real-time reporting on EFIN activity.

Mitigating Risk of Fraud and Identity Theft
In 2026, the IRS has increased its focus on "ghost preparers" and fraudulent EROs. To differentiate your business and protect against audits:
- Avoid Excessive Deductions: Encourage clients to use real-time expense tracking and mileage logs rather than estimates.
- Verify Bank Information: Incorrect bank account numbers for refunds are a frequent cause of IRS inquiries. Implement a double-verification process for all direct deposit entries.
- Income Reporting: Before filing, reconcile all third-party income documents (1099s, W-2s) with the IRS Wage and Income transcripts if available.
Conclusion
ERO audit protection in 2026 requires a proactive, technology-driven approach to compliance. By adhering to IRC Section 6695(g), maintaining a current WISP, and performing regular internal audits, EROs can safeguard their business against the risks of the current tax landscape. Compliance is not an annual event but a daily operational requirement.
