Large corporations interested in resolving federal tax issues with the IRS before filing their returns have a limited window to apply for a program designed to do exactly that. The Internal Revenue Service announced on September 8 that it is accepting applications for the 2027 Compliance Assurance Process, commonly known as CAP. The application period runs through October 30, 2026, and the IRS expects to notify applicants in February 2027 about whether they have been accepted. Unlike a traditional IRS examination that occurs after a tax return has been filed, CAP is built around identifying and resolving potential tax issues in real time.
