Say a reviewer overrides a diagnostic on a client's Schedule C mileage deduction in March, and writes one sentence explaining why. The return goes out clean. The note isn't lost — it's still sitting exactly where it was written, inside that year's engagement file. Eleven months later, a different preparer opens the same client's file for the new season, looks at the same mileage figure, and has no idea the note, or the override it explains, ever existed.
Archived is not the same as findable
Tax software organizes by engagement year. Roll a client's file forward into a new season and the software builds a fresh engagement from the old one's numbers — it does not open a window into the old one's notes. The prior file doesn't vanish; it becomes read-only, sealed inside last season's closed folder. Finding what's in it means already suspecting something is there, then going looking for it, on this specific line, in a file nobody has a routine reason to reopen once the return inside it is filed.
Written
A reviewer attaches a note to the line it explains, at the moment the override or judgment call is made.
Filed
The return goes out. The note stays exactly where it was written, inside a file that is about to close.
Archived
The engagement rolls into read-only storage once next season's file is generated from it — a normal step, not a loss.
What it would take to find it
A preparer would need to already suspect something, then open a closed prior-year file and locate this exact line.
Unfindable
Next season's return opens fresh. Nothing in the new file points back to the old one, so the override looks like it was never questioned.
What the newest standard actually says about this
Until December 2025, no professional standard named a review note as a category of documentation at all. The only retention duty on the books belonged to the return itself: 26 CFR § 1.6107-1 requires a preparer to keep a copy, or at minimum the taxpayer's name and identifying number, for three years — a rule about the output, silent on the reasoning behind it. Statement on Quality Management Standards No. 1, effective December 15, 2025, changes the first half of that. Not the second.
SQMS No. 1 lists supervision and review notes among the evidence a firm's quality-management system can point to. It stops short of saying how long they have to survive, or in what form: each firm writes its own retention policy, sufficient to let the firm and its peer reviewer monitor the system — "practical," in the AICPA's own framing, meaning long enough to show trends but not so long as to create unnecessary clutter. A firm can satisfy the standard with a policy that never once asks whether next year's preparer can find anything.
None of this calls for more storage — the note is already archived exactly the way SQMS No. 1 expects. What's missing is a path from this year's return back to the reasoning that explains a line on it, one that doesn't depend on next year's preparer already suspecting it's there to look for. Pernee attaches a reviewer's note to the return line it explains and keeps that link live across tax seasons, so the note surfaces by opening this year's return — not by searching last year's closed file for something nobody knew to ask about.
