When it comes to filing taxes electronically, there’s a key role in the process that many people may not know about. That role is called an ERO.
So, what is an ERO in taxes? ERO stands for Electronic Return Originator—a tax professional authorized by the IRS to submit tax returns electronically on behalf of clients.
If you’re new to the tax industry or simply want a better understanding of how electronic filing works, this article will break down what an ERO is, what they do, and why their role is essential—whether you’re preparing taxes professionally or filing your own.

What Does ERO Stand For?
ERO stands for Electronic Return Originator. This is the person or business that starts and submits electronic tax returns to the IRS. In other words, the ERO is responsible for sending the taxpayer’s information from the software directly to the IRS through the IRS e-file system.
Anyone who files tax returns electronically must go through an ERO, either directly or through a tax business that acts as one.
What Does an ERO Do?
The role of the ERO includes several key responsibilities:
- Entering taxpayer information into tax preparation software
- Verifying that the return is accurate and complete
- Ensuring the taxpayer signs the return (either electronically or on paper)
- Transmitting the return to the IRS electronically
- Monitoring the return to confirm it is accepted by the IRS
In many small tax businesses, the ERO is also the tax preparer. However, in larger offices, these may be two separate roles.
How Do You Become an ERO?
To become an ERO, you must be authorized by the IRS. This requires applying to the IRS e-File Program and completing the following steps:
- Get a PTIN (Preparer Tax Identification Number)
Anyone who prepares taxes for compensation must have a PTIN. - Apply for an EFIN (Electronic Filing Identification Number)
This is done through the IRS online portal and involves submitting an application, verifying your identity, and undergoing a suitability check. - Pass a Background Check
The IRS will review your credit history, tax compliance, and possibly conduct a criminal background check.
Once approved, you are allowed to file electronic tax returns as an ERO using your EFIN. Tax season software can then help streamline the process by providing the tools needed to efficiently prepare and submit returns electronically. Many tax preparers rely on specialized tax season software to simplify the process, ensure accuracy, and meet IRS requirements for e-filing.
Do You Have to Be a Tax Preparer to Be One?
Not always. While most EROs are also tax preparers, it is possible for a person or business to act solely as an ERO. That means they transmit the return but may not actually prepare it.
Still, many tax preparers apply to become EROs so they can manage the full tax filing process for their clients under their own business name and EFIN. By doing so, they can integrate tax prep software with bank products, offering clients additional services such as refund anticipation loans or direct deposit options, enhancing the overall tax preparation experience.
Why Becoming an ERO Matters for Tax Professionals
For tax preparers, what is an ERO in taxes? It’s an Electronic Return Originator (ERO), and being one gives you greater control and flexibility over the filing process. Instead of relying on another company’s EFIN, you can file returns through your own business, with your own credentials. This allows you to operate independently, manage your own pricing, and build trust with your clients.
Here are a few benefits of becoming an ERO:
- File returns under your own brand
- Keep more of your revenue
- Manage your own clients directly
- Grow your business without limitations
It also helps tax professionals stay compliant with IRS rules by giving them full access to filing records, software tools, and IRS acknowledgments.
What If You Have a Low Credit Score?
TThe IRS does conduct a suitability check when you apply for your EFIN, which includes a review of your credit history. However, a low credit score alone will not automatically disqualify you.
The IRS looks at your overall background, including whether you have any criminal history or unresolved tax debts. Many people with less-than-perfect credit have still been approved.
Being honest and transparent on your application is important. If you have concerns about qualifying, it’s helpful to work with a company that understands the process and can guide you through it, especially if you plan to use service bureau tax software. These software solutions are designed to streamline the filing process and ensure compliance, providing a reliable option for both experienced and new tax professionals.
What is an ERO in Taxes? What’s the Difference Between an ERO and a Tax Preparer?
While the roles are often combined, it’s important to understand the difference.
A Tax Preparer is the person who prepares the return by entering the taxpayer’s income, deductions, and credits.
An ERO (Electronic Return Originator) is the person or business that submits the return electronically to the IRS. So, when you ask What is an ERO in taxes?—it’s essentially the professional or business responsible for ensuring that the tax return is properly filed electronically.
Both roles are important, and both require proper authorization. If you are doing both, you will need a PTIN and an EFIN.
