IRS Releases Updated ACA Information Returns (AIR) Submission Composition and Reference Guide


The IRS has released the latest version of Publication 5258: “ACA Information Returns (AIR) Submission Composition and Reference Guide.” The guide has been updated for use in 2019.

This publication is meant to assist various entities with electronic information return (AIR) submissions required under the ACA — Forms 1094-B and 1095-B under Section 6055, and Forms 1094-C and 1095-C under Section 6056.

The guide includes information on the process for applying for the program, technical requirements and updates to the 2019 version, what testing is necessary before the actual transmission, parameters for filing, and data file size limits. The technical nature of this reference guide reinforces the need for employers to partner with an IT professional (either in-house or external) or experienced vendor if planning to file ACA information returns electronically.

As a reminder, if you’re a self-insured employer or an applicable large employer, the deadline to provide information returns to employees or responsible individuals is Jan. 31, 2019, for tax year 2018. Also, employers filing 250 or more forms must file electronically with the IRS. Employers filing fewer than 250 forms may file by paper or electronically. Paper filings are due by Feb. 28, 2019. Those filing electronically must report 2018 data by April 1, 2019 (since March 31, 2019 falls on a weekend).
