IRS IRIS Taxpayer Portal is a free web service for filing information returns through the portal or Application to Application (A2A). In the portal, filers can enter returns manually or upload CSV files, manage issuer information, keep filing records, download payee copies, submit corrections, and request automatic extensions. Portal access requires an IRIS Transmitter Control Code, a five-digit code used only for IRIS. IRIS accepts returns for tax year 2022 and later. Filers with their own or third-party software can use A2A for thousands of returns, with uploads up to 100 MB at a time; setup requires an A2A TCC, API Client ID, schema package, and successful Assurance Testing System transmissions. CSV templates and formatting guidance are available in the portal. Starting with tax year 2023, filers with 10 or more information returns must file electronically; Forms W-2 go to the Social Security Administration. For processing year 2026, supported forms are listed for tax years 2025, 2024, and 2023, with additional forms available only through the portal. PDF notifications can take up to 10 minutes, and company firewalls may block external downloads.
