Some of our customers have reported issues with being able to find the IRS upload pages for either Test files or Production files. Here is a new link to open the IRS site where you can select which channel you want to use and then log in to upload your files, obtain your Receipt ID, and then check the status of your submission and (in the case of Production files) Download your Acknowledgement file.
After clicking on the link below an IRS web page will open. Scroll down on the far right-hand side under the header UI Channel Link, and then choose either the AIR UI Channel Login – AATS (Testing) for uploading Test files, or AIR UI Channel Login – Production for uploading your actual production files.
