7 Mistakes You’re Making with ERO Operations (and How to Fix Them)
Operating as an Electronic Return Originator (ERO) requires more than tax knowledge. It requires strict adherence to IRS guidelines, robust data security protocols, and efficient business systems. Many tax business owners focus exclusively on tax preparation while neglecting the operational infrastructure that protects their EFIN and ensures long-term viability.
Below are seven common operational mistakes identified in the tax professional industry and the specific actions required to correct them.
1. Compromised EFIN Security and Monitoring
The Electronic Filing Identification Number (EFIN) is the most critical asset of an ERO. A common mistake is failing to monitor the EFIN activity through the IRS e-services portal. Many owners do not realize their EFIN has been compromised or used for unauthorized returns until they receive a letter from the IRS.
The Fix:
Log into your IRS e-services account at least once a week during peak tax season and monthly during the off-season. Verify the number of returns transmitted under your EFIN. If the count on the IRS website does not match your internal software records, contact the IRS e-help desk immediately. Additionally, never share your EFIN credentials with unauthorized staff or third-party preparers without formal agreements and background checks.
2. Absence of a Written Information Security Plan (WISP)
The FTC Safeguards Rule and IRS Publication 4557 require all "financial institutions," which includes professional tax preparers, to have a Written Information Security Plan (WISP). Operating without a WISP is a violation of federal law and puts your business at risk of heavy fines and the loss of your EFIN.
The Fix:
Develop and implement a comprehensive WISP tailored to your specific office size and complexity. This document must outline how you protect client data, who is responsible for the program, and how you handle data breaches.

3. Inadequate Due Diligence Processes
IRS Section 6695(g) imposes significant penalties for failure to exercise due diligence regarding the Earned Income Tax Credit (EITC), Child Tax Credit (CTC), and Head of Household filing status. Many EROs rely on verbal confirmations from clients without documenting the interview process or retaining required records.
The Fix:
Standardize your intake process. Use digital checklists that mirror Form 8867 requirements within your tax software. Ensure all staff members are trained to ask probing questions when information appears inconsistent or incorrect. Retain copies of all documents used to determine eligibility for at least three years from the return's due date.
4. Relying on Consumer-Grade Software and Hardware
Using retail-level tax software or unencrypted hardware is a significant operational bottleneck and security risk. Consumer-grade products lack the multi-user capabilities, diagnostic tools, and administrative controls necessary to run a professional ERO operation.
The Fix:
Invest in professional-grade tax software designed for EROs and Service Bureaus. This software should offer bank product integration, remote signature capabilities, and robust reporting. Ensure your office hardware meets the minimum requirements for the software to prevent system crashes during high-volume periods.

5. Failure to Implement Tiered Staff Oversight
In many tax offices, the ERO acts as the primary preparer, office manager, and technical support. This lack of delegation and oversight leads to errors in tax preparation and administrative oversights. Without a clear hierarchy, individual preparers may file returns that have not been properly reviewed, leading to increased rejection rates and potential audits.
The Fix:
Establish a clear organizational structure. Every return should undergo a secondary review by a senior preparer or the ERO before transmission. Use tax software with administrative "queues" that prevent preparers from hitting "send" until the ERO has electronically signed off on the file.
6. Ignoring State-Specific Compliance Requirements
While federal compliance is a priority, EROs often overlook state-specific mandates. For example, states like California and Texas have specific registration and bond requirements for tax preparers that differ from federal PTIN requirements. Failing to maintain state compliance can result in the suspension of your right to file returns in that jurisdiction.
The Fix:
Conduct a quarterly audit of your state licenses, bonds, and registrations. If you operate in multiple states, maintain a compliance calendar to track renewal dates. Professional organizations like TIG Tax Pros help EROs navigate the complexities of multi-state operations and regulatory changes.

7. Poor Client Data Management and Retention
Manual document management is inefficient and prone to security breaches. Storing physical copies of sensitive client data in unlocked filing cabinets or unsecured offices is a violation of the Safeguards Rule. Furthermore, failing to have a digital backup plan can lead to total data loss in the event of hardware failure or natural disaster.
The Fix:
Transition to a paperless environment using secure, cloud-based document storage. Ensure all client files are encrypted both at rest and in transit. Implement a formal data retention and destruction policy that specifies how long records are kept and how they are permanently destroyed once the retention period expires.
Operational Infrastructure for Growth
Correcting these mistakes is the first step toward scaling a tax business. Many EROs hit a plateau because their manual processes cannot handle higher volumes. By automating due diligence and securing your EFIN, you create the bandwidth necessary to focus on marketing and client acquisition.
Partnering with a Service Bureau can alleviate many of these operational burdens. A Service Bureau provides the software, training, and backend support required to maintain high standards without the ERO needing to manage every technical detail.
