The IRS inaugurated IRIS, their successor to the FIRE system, on Monday, January 23, 2023. The system has 2 components (1) a web application or portal and (2) an API server.

IRIS Portal

The portal URL is: https://la.www4.irs.gov/irportal/.

Business owners or their accountants may:

• enter data into the web application. See IRIS portal screen shots.
• or upload a CSV file for processing.

IRIS API Server

It appears that the API portion of the system will not be active until May 2023. Acceptance testing will be required for submitters to IRIS.

IRIS CSV

The IRIS portal accepts data in CSV format.

See IRIS CSV file formats.

IRIS XML

The IRIS API accepts data in XML format.

See IRIS XML data structures.
