Federal and State E-File Program
Introduction
The modernized e-file system has changed how federal and state tax returns are filed in the United States.It allows taxpayers and professionals to submit returns online using a secure IRS platform.
This system also supports the federal and state e-file program under one submission process. As IRS guidance confirms, modernized e-file improves speed, accuracy, and tracking.
What Is the Modernized E-File System?
The modernized e-file system, also called MeF, is an IRS-developed platform that allows electronic filing of tax returns using XML format. It replaces older legacy e-file systems and supports individual, business, and information returns.
The IRS uses built-in business rules to validate data before processing.As per IRS documentation, this structure helps reduce errors and manual intervention.
How Does the Federal and State E-File Program Work?
The federal and state e-file program works as a single submission channel for eligible filers
Federal Submission
- The taxpayer or authorized provider prepares both federal and state returns
- IRS-approved tax software is mandatory
Transmission to IRS
-
Both returns are transmitted together to the modernized e-file system
-
The IRS validates the federal return and issues an electronic acknowledgment
Forwarding to State
-
Once accepted, the IRS forwards the state return data
-
This forwarding is provided at no additional cost
State Processing
-
The state revenue department reviews the return
-
A separate state acknowledgment confirms acceptance or rejection
This flow is officially described by the IRS and state revenue authorities.
What Are the Key Benefits of Modernized E-File?
The modernized e-file system offers clear operational and compliance benefits.
- Faster acknowledgments through near real-time processing
- Electronic payment authorization during filing
- Built-in validation rules that reduce filing errors
- Reduced paper usage and manual handling
IRS guidance highlights that these benefits directly reduce return rejections and delays.
Who Can Participate in the State E-File Program?
Participation in the state e-file program depends on the filing method and role.
-
Individual taxpayers typically file through commercial software
-
Businesses rely on authorized e-file providers
-
Software developers and transmitters must register with the IRS
-
IRS testing and approval are mandatory before participation
Some states may still require separate filing despite federal acceptance. For example, the District of Columbia follows specific independent procedures.
What Should Filers Know Before Using Modernized E-File?
While modernized e-file simplifies filing, filers must follow business compliance rules.
-
Use only IRS-approved tax software
-
Confirm state participation before relying on combined filing
-
Review acknowledgments from both the IRS and state authorities
-
Maintain filing records for audit and verification
IRS documentation clearly states that federal acceptance does not always guarantee state acceptance.
