E-file compliance for tax firms starts with ERO responsibilities

IRS e-file compliance is not limited to a single person listed on the firm’s e-file application. For many tax firms, electronic filing is a shared workflow involving preparers, reviewers, administrative staff, office managers and firm owners. 

An electronic return originator, or ERO, is the authorized IRS e-file provider that originates the electronic submission of a tax return after the taxpayer authorizes the filing. The ERO may also prepare the return, but return preparation and electronic origination are separate responsibilities; a preparer may not be the ERO personally, but may still be part of the process that supports the ERO’s compliance duties.

Quick review of ERO compliance

• Tax firms that e-file returns should review their ERO procedures before filing season pressure begins.
• Publication 1345 is the IRS handbook for authorized IRS e-file providers of individual income tax returns.
• ERO compliance includes taxpayer authorization, return transmission, record retention and rejected return procedures.
• Firms should also review EFIN access, data security and staff responsibilities before returns begin moving through the workflow.

Publication 1345 sets the ERO compliance framework

Publication 1345, Authorized IRS e-file Providers of Individual Income Tax Returns, provides the rules and requirements for participation in IRS e-file for individual income tax returns and related forms. The publication covers how providers handle taxpayer signatures, supporting documents, return copies, acknowledgment files, rejected returns and record retention.

Firms should make sure the person responsible for e-file compliance knows where Pub. 1345 fits into the firm’s procedures. It should also be part of staff training for anyone who helps collect signatures, transmit returns, monitor acknowledgments or communicate with clients about rejected returns.

Identify who handles ERO responsibilities in the firm

Before filing season begins, firms should identify who serves as the ERO and who supports the ERO’s workflow. The ERO is usually the first point of contact for taxpayers using IRS e-file, but the firm’s process may involve multiple people.

A practical preseason review should answer four questions:

1. Who is listed on the firm’s IRS e-file application?
2. Who has access to the firm’s EFIN and e-services account?
3. Who is responsible for confirming taxpayer authorization before transmission?
4. Who monitors acknowledgments, rejections and follow-up communication?

These questions help clarify responsibility before returns begin moving through the firm’s e-file workflow.

Review the firm’s e-file application and EFIN access

The firm’s e-file application should stay current. Firms should also consult Publication 3112, IRS e-file Application and Participation, for guidance on the e-file application process, EFIN responsibilities and continued participation in IRS e-file. Changes involving principals, responsible officials, provider options, addresses or contact information generally require an update to the e-file application, and some business-structure changes require a new application. Firms should also monitor EFIN activity and protect access to IRS e-services.

An EFIN should be treated as a critical IRS-issued identifier for e-filing operations. Unauthorized use or outdated application information can create serious filing-season disruption, especially if the firm does not catch suspicious filing activity early. Before the season begins, firms should confirm that application details are accurate and access controls are current. Staff permissions, login credentials and EFIN monitoring procedures should also be reviewed.

Confirm Form 8879 procedures before returns are transmitted

Form 8879, IRS e-file Signature Authorization, is the declaration document and signature authorization for an individual e-filed tax return filed by an ERO. It is used when the practitioner PIN method applies or when the taxpayer authorizes the ERO to enter or generate the taxpayer’s PIN.

This is one of the most important workflow points for preparers and administrative staff. A return should not be transmitted before the taxpayer has properly authorized the filing. Firms should review how Form 8879 is delivered, signed, returned, stored and retained.

A strong process should make clear:

• Taxpayers must review the return before signing.
• The signed authorization must be received before transmission.
• The firm must retain the form for the required period.
• Staff should know where the signed authorization is stored.

Know when Form 8453 is required for e-filed returns

Even when a return is filed electronically, some supporting documents may still need to be sent to the IRS. Form 8453, U.S. Individual Income Tax Transmittal for an IRS e-file Return, is used to send certain required paper forms or supporting documentation listed on the form.

Firms should train staff to recognize when Form 8453 is required. This is especially important for returns involving certain attachments, elections or supporting forms. A return may be e-filed but required paper support still must be timely sent when Form 8453 applies.

Keep ERO records ready for IRS review

ERO recordkeeping is another area where the firm’s e-file workflow needs clear procedures. EROs must retain required materials and make them available to the IRS upon request. This includes items such as Forms 8878 and 8879, copies of Forms 8453 and supporting documents not included in the electronic record, acknowledgment files and a complete copy of the electronic portion of the return.

Firms should also make sure their storage system supports readability and retrieval. It is not enough to have the records somewhere. The firm should be able to readily locate and reproduce them if the IRS requests them.

Track IRS acknowledgments and rejected e-filed returns

The e-filing process does not end when the return is transmitted. Firms must monitor IRS acknowledgments and returns rejected by the IRS. A rejected electronic return is not filed until the rejection is corrected and the return is accepted, or the taxpayer files using another permitted method.

Before filing season, the firm should assign someone to review acknowledgments, identify rejected returns, determine whether errors can be corrected and communicate with taxpayers when needed. Firms should retain acknowledgment files and related records, and it is prudent to document the steps taken, especially when a rejection affects filing deadlines.

Build taxpayer data security into the e-file workflow

Publication 1345 sets out data security expectations for authorized e-file providers, and firms should treat that security as part of e-file compliance. EFIN protection, account access, phishing awareness, and taxpayer data safeguards should be reviewed before filing season begins and monitored throughout the year.

Firms should review who has access to e-file systems, whether passwords and multifactor authentication are properly managed, how taxpayer documents are transmitted and how suspicious activity and confirmed security incidents are reported. Small firms are not exempt from data security risk. In many cases, they are attractive targets because they hold sensitive taxpayer information and may have fewer formal controls.

Apply ERO rules across the firm’s e-file process

For tax professionals, the practical takeaway is simple: ERO compliance should be built into the filing workflow, not handled as a last-minute technical issue or overlooked as unimportant. A firm does not need every preparer to become an e-file compliance expert, but every person touching the e-file process should understand their role.

Before filing season, firms should schedule a brief internal review of Pub. 1345 procedures, EFIN access, Form 8879 handling, rejected-return tracking and data security controls. The review can reduce filing disruptions, improve client communication and help the firm respond more confidently if the IRS requests records.

ERO compliance is not just about transmitting returns. It is about ensuring the firm’s entire e-filing process is authorized, documented, secure and ready for filing season.
