What Is an ERO? How to Become an Electronic Return Originator
You got your PTIN, learned how to prepare returns, and started building a client base. Now you’re thinking about taking the next step and operating your own tax office.
That move may mean becoming an Electronic Return Originator, commonly called an ERO.
But let’s get something straight: becoming an ERO is bigger than buying professional tax software and putting “CEO” in your bio. You are stepping into ownership, compliance, data security, team leadership, and responsibility for the electronic filing operation behind your business.
Here is what you need to know before making that move.
What Is an Electronic Return Originator?
An Electronic Return Originator is an authorized IRS e-file provider that originates the electronic submission of a tax return to the IRS after receiving authorization from the taxpayer.
The ERO is often the first point of contact for taxpayers using IRS e-file.
An ERO may:
Prepare tax returns
Receive completed returns directly from taxpayers
Collect required taxpayer signatures
Verify taxpayer information
Submit returns electronically
Maintain required records
Manage tax preparers working under the firm
Protect sensitive taxpayer information
Monitor acknowledgments and rejected returns
The IRS explains the ERO role in its Electronic Return Originator technical fact sheet.
What Is an EFIN?
EFIN stands for Electronic Filing Identification Number.
An EFIN identifies a firm that has completed the IRS e-file application process and received approval to participate as an authorized IRS e-file provider.
Your PTIN identifies you as an individual paid preparer. Your EFIN identifies the approved firm electronically filing returns.
An EFIN:
Belongs to the approved firm
Is issued after the e-file application and suitability process
Is required for an approved firm to electronically file returns
Cannot be transferred to another person or business
Must be protected against unauthorized use
Does not replace the PTIN requirements for paid preparers
The IRS currently does not charge a fee to obtain an EFIN, but the firm must apply and pass the suitability process.
Review the official IRS EFIN frequently asked questions.
ERO vs. Tax Preparer: What Is the Difference?
A tax preparer prepares or substantially assists in preparing tax returns for compensation. That person generally needs a valid PTIN.
An ERO operates within an authorized IRS e-file firm and originates the electronic submission of returns.
One person can be both a paid tax preparer and an ERO, but the responsibilities are different.
As a preparer, you are responsible for preparing accurate returns, completing due diligence, signing the returns you prepare, and using your PTIN properly.
As an ERO, you are also responsible for the electronic filing process, required authorizations, recordkeeping, security, and the activities performed under your firm’s EFIN.
This is why becoming an ERO is not simply a title upgrade. It is a business and compliance upgrade.
How Do You Become an ERO?
To become an ERO, your firm must apply to become an authorized IRS e-file provider.
The general process includes:
Access the IRS e-file application through e-Services
Enter the firm’s legal and business information
Identify the principals and responsible officials
Select the Electronic Return Originator provider option
Complete required identity-verification or fingerprinting steps
Submit the application
Pass the IRS suitability check
Receive the firm’s approval and EFIN
The IRS states that processing may take up to 45 days after submission. Handle this before filing season - not when clients are already waiting.
Start through the official IRS authorized e-file provider application.
What Is the IRS Suitability Check?
The IRS uses the suitability process to determine whether an applicant should be authorized to participate in IRS e-file.
The process may review:
Tax compliance
Criminal background
Prior noncompliance with IRS e-file requirements
Professional licensing status, when applicable
Other information related to the applicant’s suitability
Not every person connected to an application will necessarily complete the same process. Follow the instructions provided through the official application.
Answer every question truthfully. This is not the time to get creative with the facts.
How Long Does It Take to Receive an EFIN?
The IRS advises applicants that approval can take up to 45 days from submission.
Applications with incomplete information, identity-verification issues, suitability concerns, or missing steps may take longer.
Apply early enough to:
Address application problems
Select professional software
Complete software training
Establish bank-product relationships
Create office procedures
Test your client workflow
Recruit and train preparers
Begin marketing before tax season
Waiting until January to build an entire tax office is not boss behavior. That is panic with a logo.
What Responsibilities Does an ERO Have?
An ERO must follow applicable IRS e-file rules, including the requirements found in Publication 1345.
Responsibilities may include:
Receiving taxpayer authorization before filing
Verifying required taxpayer information
Maintaining applicable records
Safeguarding taxpayer data
Using the correct EFIN
Protecting the EFIN from unauthorized use
Monitoring IRS acknowledgments
Correcting rejected returns
Following electronic-signature requirements
Ensuring returns are not filed before all required tax documents are received
Authorized providers should review the current IRS Publication 1345, which contains rules and requirements for participating in IRS e-file.
How Do You Protect Your EFIN?
Your EFIN is not something you lend out, sell, or allow random preparers to use.
The IRS states that an EFIN is not transferable. You must protect it from unauthorized use.
Protect your EFIN by:
Limiting access to authorized individuals
Reviewing preparer and return activity
Using strong passwords and multifactor authentication
Keeping your e-file application current
Removing individuals who no longer work with your firm
Monitoring return counts for suspicious activity
Reporting suspected compromise quickly
Verifying software and service-bureau relationships
The IRS continuously reviews EFIN activity and may deactivate an EFIN that appears compromised.
Review the IRS guidance on maintaining and protecting your EFIN.
Do EROs Need a Written Information Security Plan?
Yes. Tax professionals handle highly sensitive personal and financial information.
Federal law requires professional tax preparers to create and implement a Written Information Security Plan, commonly called a WISP.
Your plan should address:
How taxpayer data is collected
Where information is stored
Who can access it
Password and authentication standards
Device and network security
Employee training
Data backup and recovery
Incident-response procedures
Record retention and secure disposal
Security is not an optional add-on you handle after making money. It is part of operating the business legally and professionally.
Do You Need Professional Tax Software?
An ERO needs professional software that supports the firm’s filing needs, team structure, security requirements, and business model.
Before selecting software, ask:
Which return types are supported?
Is software training included?
What technical support is available?
Can you add PTIN preparers?
What transmission and service-bureau fees apply?
Are bank products available?
How are electronic signatures handled?
Does it support secure document collection?
Can you monitor preparer activity?
What business support is included?
Do not select software based only on a cute promotional price. You need to understand the full fee structure, included support, and how the system will serve your operation during filing season.
How Do EROs Make Money?
An ERO may generate revenue through:
Tax preparation fees
Document preparation fees
Electronic filing fees
Audit-assistance services
Bookkeeping or payroll
Business tax preparation
Tax planning
Training or team-development services
Software reseller opportunities, when authorized
Service bureau growth, at an advanced level
Your exact services, fees, disclosures, and operations must comply with applicable laws, provider agreements, and professional requirements.
The goal is not to add random charges because you saw somebody else doing it. Build a transparent fee structure tied to real services and value.
Are You Ready to Become an ERO?
You may be ready if:
You already prepare returns accurately
You understand due diligence
You are ready to manage an independent tax office
You can protect taxpayer information
You understand e-file responsibilities
You have procedures for intake, review, signatures, filing, and follow-up
You are prepared to lead PTIN preparers
You can market consistently
You want ownership and accept the accountability attached to it
You may need more preparation if:
You still need every return reviewed
You do not understand basic compliance procedures
You have no security plan
You are unfamiliar with professional software
You have no client workflow
You want an EFIN only because the title sounds impressive
You expect software to build the business for you
There is no shame in building your skills before stepping into ownership. The real mistake is moving too fast and putting clients, your EFIN, and your reputation at risk.
