The Internal Revenue Manual, commonly called the IRM, is the IRS’s principal compilation of internal operating instructions. In a collection matter, it can help identify how cases are assigned, how financial information is analyzed, how levies and liens are processed, and how collection alternatives are evaluated.
What the Manual is good for
- Locating the procedures assigned to a Revenue Officer or collection function.
- Understanding transaction codes, internal terminology, and case routing.
- Identifying documentation and managerial-approval requirements.
- Comparing what happened in the account with published agency procedure.
What the Manual cannot replace
The Manual is not the Internal Revenue Code, a Treasury regulation, or a judicial decision. An IRM provision should not be cited as though Congress enacted it. When the issue is levy authority, hearing rights, a limitation period, or the legal standard for relief, the analysis must return to the controlling authority.
Versions and dates matter
The online Manual changes as sections are revised. Research involving older collection action may require the version in effect when the action occurred. A current page can accurately describe today’s process while failing to show the instruction applicable to an older event.
