Nobody reviews their own work well. Firms accept this in principle. Review is a separate stage, staffed by a different person, and no partner would sign a return that had only ever been read by the preparer who built it.
What firms agree on less is what that second person is for. In a calm week, review means an independent reading of the judgment inside a file. By the third week of September, it often becomes a scan for obvious errors, because that is all the time anyone has.
This article describes how our review layer works: what the reviewer receives, what they are required to do with it, and what happens when they disagree with the preparer. The detail matters, because “two-EA reviewed” is a phrase anyone can print on a website.
What the second reader is for
A preparer who has spent four hours inside a return ends up knowing what it is supposed to say. That knowledge is most of the value of the four hours. It is also what makes them the worst available reader of the finished file. They see the return they meant to build.
The mistakes that survive this are the ones that look right. A treaty position taken in March and never revisited after the facts changed. A carryforward carried over from a return somebody else prepared. An election that made sense under last year’s numbers and quietly stopped making sense under this year’s.
A second enrolled agent has no memory of any of those decisions. They have the file and nothing else. That absence is the qualification.
The reviewer does not start with the return
When a reviewer opens a case on our platform, the draft return is not the first thing in front of them. Four other things are.
The preparer’s note comes first: a short written statement of where to look and what they were unsure about. A preparer who flags their weakest position is not confessing to a weakness. They are aiming the review.
Next is the preparer’s own grading of the return, on two scales of one to five — how complex the work was, and how much effort it took to get what was needed from the client. The reviewer uses it to calibrate. A five-out-of-five return earns a slower pass; a one-out-of-five rarely needs much.
Third is a written summary of what moved against the prior year, so the reviewer knows where the surprises are before reading a single schedule.
Only then comes the draft return itself, with the preparer’s workpapers and the client’s original source documents open alongside it. A reviewer who wants to check a figure against the document it came from does not have to go looking for the document.
Sending it back is the expensive part
A reviewer has two available actions. Approving moves the return forward to filing. Sending it back requires a comment, and the comment is the whole control.
“Page 4, line 17: the foreign tax credit shows $1,200, and the Form 1042-S in the source documents shows $1,500. Verify.” That is a send-back. “Please fix” is not, and our reviewers are not permitted to leave it.
The reason is arithmetic of a different kind. Each round trip between reviewer and preparer costs roughly two days of elapsed time, and in October a firm does not have many of those to spend. One complete comment is cheaper than three partial ones. When the preparer resubmits, the draft version number increases, and the reviewer checks the new file against their own earlier comments rather than starting again.
There is a stopping rule as well. After three send-backs on the same return, we escalate rather than continue. Three rounds usually means the two people disagree about something neither has said out loud, and another lap will not surface it.
Your review is the third one
None of this removes your firm from the return. You remain preparer of record, you sign, and you file. We never sign a return or e-file under our PTIN.
What changes is what arrives on your desk. You are not receiving a finished object to approve on trust. You are receiving a file that two enrolled agents have already disagreed about, with the disagreement attached — every send-back, every comment, every version, in order, on a record that cannot be rewritten afterward. If a number looks wrong to you, the history tells you whether someone already questioned it and what they were told.
Senior preparers tend to be the last people in a firm to warm to outsourced preparation, and the first to like this part once they see its shape. The review layer does not compete with their judgment. It moves their judgment to the end of the chain, where it is worth the most.
What this actually replaces
In most firms of two to ten preparers, the second reading is done by the partner, and partner review is the scarcest hour in the building. It is also the first thing compressed when the pile gets deep — not because anyone’s standards drop, but because there is only one of them and the deadline does not move.
A second enrolled agent, reviewing before the file ever reaches you, gives that hour back. You still read the return. You read it after somebody else already has, with their objections in front of you, which is a different and much shorter job than being the only line of defence in the last week of September.
