The IRS announced this month that it is removing 71 revenue rulings, revenue procedures, notices, and announcements it previously published. Most tax pros will skim the headline and move on. That is a mistake, because the real exposure is not at the IRS. It is in your own files.
Think about where old citations live in a small firm: engagement letter language, client email templates, planning checklists, research memos, the folder of "how we handle this" notes that a long-gone senior wrote in 2017. Nobody maintains these. They just get copied forward, season after season, with the same authority attached.
Why this matters
Under Circular 230 Section 10.22, practitioners must exercise due diligence as to the accuracy of what they prepare and advise. A citation to guidance that has since been removed does not automatically make your advice wrong. But it does mean someone should have checked, and "we have always cited it" is a weak answer in an exam or a malpractice conversation.
There is a second problem. Position memos and reasonable-cause files often lean on specific authority. If a file for a client you advised years ago rests on guidance that is now gone, you want to learn that on your own schedule.
A 60-minute audit
You do not need a project plan. You need an hour and a search box.
Start with the list. Pull the full list of removed items from the IRS announcement on IRS.gov. Read how the IRS describes each category of removal, since withdrawn, superseded, and obsolete do not mean the same thing.
Search your own files. Run each document number through your document management system, shared drive, template folder, and any research tool where staff saves notes. Do not forget email templates and the engagement letter library.
Sort the hits. For each one, decide whether the citation is simply outdated housekeeping, whether it needs to be replaced with current authority, or whether the underlying advice needs a second look. Most will land in the first bucket. A few may not.
Fix and date-stamp. Replace the reference, note the date you reviewed it, and initial it. Future you will be grateful.
Check open client files. If a current-year position or a planning recommendation relied on a removed item, document your conclusion on whether it still stands.
Make it a habit
The IRS will do this again. Guidance cleanups, new notices, and superseded procedures are a permanent feature of the job. Turn this hour into an annual one. Pick a date, perhaps the slow weeks in the fall, and review your templates and checklists against what has changed.
Assign one person to own the firm’s knowledge base. Give your staff a simple rule: if you cite it in something that will be reused, put the date you checked it next to it. That single habit makes every future audit a ten-minute job.
This is not glamorous work. But your reputation rests on whether your files are right, not on whether you read the news. If the IRS just cleaned house, spend an hour cleaning yours.
