Key takeaways

  • A signature shows who signed a file; a Firm can use a sign-off packet to show what was checked before they signed.
  • The Firm can choose six starting lines: file index, tie-outs, sample plan, notes, open items and sign-off.
  • The Firm can have each line identify the relevant record already in the file, with counts where relevant.
  • The Firm can make the packet the Reviewer's last step and decide how an incomplete line affects sign-off.
  • The Firm can keep open items on the page with an owner and a reason, and decides which ones can stand at sign-off.
  • The Firm can use the packet to record what was checked and leave the judgment that the file is right with the Reviewer who signed.

A signature on a file shows who signed it. It doesn't show what they checked. On a file where an AI tool drafted the entries, the checks are spread across the folder: a tie-out line here, a readback record there, a stack of cleared notes somewhere else. The Firm's packet can point to those records; it doesn't establish that they are sound. Put together, they still leave a later reader digging through the whole file to learn what was done.

The Firm can use a one-page sign-off packet to index those records. The Firm can place it on top of the file to index the checks people already did. The Firm can have the tool draft the entries and people check them. The Firm can ask the Reviewer to assemble the packet before deciding whether to sign off.

This post covers what goes on that page, how the Reviewer fills it, and how someone opening the file later reads it.

What goes on the page

The Firm picks the lines. The Firm can start with these six lines and adapt them to its file.

File index. Which version of the file index the review used, and how many documents it lists. The Firm can use that line to tie the packet to a known set of source documents.

Tie-outs. How many documents have printed totals, how many were tied out, and how many are still open.

Sample plan. The Firm's chosen sample plan, its recorded result, and a pointer to the Reviewer's readback record.

Notes. How many review notes were opened and how many were cleared. The Firm can leave the notes themselves where it already keeps its review notes and carry the count on the packet.

Open items. Anything not settled at sign-off; the Firm can give each one an owner and a one-line reason.

Sign-off. The Firm can have the sign-off line record who drafted the entries, who reviewed them, who signed, and the date of each.

The Firm can have each line point to a record already in the file. The Firm can keep the packet free of new checks of its own.

Point to the records, don't copy them

The Firm can treat the packet as an index, not a summary. The Firm can have a line that says "6 of 6 tied out" also name the record behind it, such as the tie-out lines on the entry list. If the Firm uses pointers, a reader who wants the detail can follow them.

If the Firm copies the detail onto the cover page, it creates a second version of each record. Detail the Firm copies can become stale when the underlying record changes. The Firm can compare the packet's counts with the current records before sign-off.

The Firm can keep the trail behind each figure under the entry it supports, with the packet on top of the whole file pointing down to it.

Build it last, before the signature

The Firm can make the packet the Reviewer's last step before signing. The Firm can ask the Reviewer to open each record in turn and fill its line from what the record shows, not from memory or from what the Preparer said in a hand-off.

The Firm can treat a line that can't be filled as a finding. If the notes record shows five opened and four cleared, the Firm can keep the packet from saying "all cleared," and the Firm's rule can be that sign-off waits until the fifth note is cleared or listed as an open item. For a missing supporting record, the Firm can choose a follow-up owner and record the unresolved item.

The Firm decides who assembles it. The Firm can have a Preparer pre-fill the lines before hand-in and the Reviewer then check each line against its record. The Firm can require every packet line to be completed before the Reviewer decides whether to sign off.

Open items stay on the page

A Firm may close some files with something still open: a document the client hasn't sent, or a question parked for the manager. The Firm can list these on the packet. The Firm can give each open item a one-line reason, an owner and the next step.

The Firm decides which kinds of open items can stand at sign-off and who approves them. An item that touches an entry the file relies on is a different case from a document that only matters next season, and the Firm's rule can treat them differently. The Firm can leave unresolved items visible on the page for a later reader to assess.

How a later reader uses it

The packet's reader might be a manager checking the season's files, a second Reviewer, or the Preparer who picks up the client next season. Where the Firm uses the packet, that reader can start on the cover page, see what was checked and what was left open, and pick one line to test against its pointer and record.

The Firm can also use the packet to show what fell outside the recorded checks. If the Firm's sample line records 8 of 40 lower-tier entries read back, 32 fall outside that recorded sample; the reader can consult other records before deciding what further checking is needed.

The Firm can use the packet to record what was checked, not to say every entry is right; the Firm can leave that judgment with the Reviewer who signed.

A Doe example

The figures below are made up for illustration.

Jane Doe, a Preparer at Doe & Co. CPA, hands in the file for the client Doe Holdings. An AI tool drafted 52 entries from 14 documents. Pat Doe is the Reviewer.

Pat builds the packet. The file index lists 14 documents. Six of them print totals, and all six have tie-out lines, so the tie-out line reads 6 of 6 tied, 0 open. Under the Firm's sample plan, 12 entries sit in the top tier and Pat read back all 12. The other 40 sit in the rest, and Pat read back a sample of 8, with no failures. That's 20 entries read back out of 52.

The notes record shows 5 notes opened and 4 cleared. Under the Firm's rule, Pat can't fill the notes line as cleared, so she sends the fifth note back to Jane. Jane fixes the entry against its page, and Pat clears the note. The line now reads 5 opened, 5 cleared.

Under the Firm's rule, one open item stays on the page: a new account the client mentioned, which belongs in next season's file. Jane is the owner, and the next step is to request its opening statement. The Firm's manager approves it as an item that doesn't touch any entry in this file. As the Firm's process asks, Pat fills the sign-off line with Jane, herself and the date, and signs.

Next season, Morgan Doe picks up the file, reads the page first, and opens the tie-out lines to test one count.

Where TracePrep fits

TracePrep's one shipped workflow today is the Reasonable Compensation Study for an S-corporation shareholder-employee. It's a different job from this sign-off packet, and it keeps the same kinds of records:

In this sign-off packet

In the Study

The Firm can have each line point to a record already in the file

Every figure traces to its source, occupation, geography, and period, at field level

The Firm can give each open item a one-line reason, an owner and the next step

Each Preparer adjustment carries a documented rationale

The Firm can have the sign-off line record who drafted the entries, who reviewed them, who signed, and the date of each.

The audit log records who prepared, who changed what, and who approved

The Firm can place it on top of the file to index the checks people already did.

Finalized evidence stays with the Firm, with an immutable evidence manifest

The Firm can require every packet line to be completed before the Reviewer decides whether to sign off.

A qualified Reviewer controls the conclusion and signs off

We've built a TracePrep plugin that runs these steps in your Firm's workflow.

This is general information, not tax or legal advice. Your licensed professional and your Firm's Reviewer are responsible for every return and every conclusion. Keep client data inside the systems your Firm has approved. As general guidance only, not advice: if you use an AI tool with client data, firms generally look for a business or commercial plan whose terms cover how that data is handled; read the vendor's current terms before you do.

Frequently asked questions

Is the sign-off packet a second review?
No. Under the Firm's design, it adds no new check. The Firm can use it to index the checks the Preparer and Reviewer already did, so the Reviewer's work can be seen on one page instead of spread across the file.
Who fills in the packet, the Preparer or the Reviewer?
The Firm decides. This piece assumes the Firm has the Reviewer fill it as the last step before signing. A Firm can have the Preparer pre-fill the lines at hand-in, and the Reviewer then checks each line against its record.
What if a line can't be filled?
The Firm can treat that as a finding. The Firm can assign a follow-up owner for the missing record or unresolved item and identify it on the packet. The Firm can choose to hold sign-off until every line is filled.
Does a complete packet mean every entry is right?
No. The Firm can use it to show which checks were done and what they found. A Firm's sample line, for example, can show how many lower-tier entries fell inside and outside the recorded sample. Under the Firm's process, the judgment on the file belongs to the Reviewer who signed.
Can the AI tool fill in the packet?
The Firm can let the tool draft the counts from the records in the file, and the Firm can have the Reviewer check every line against its record. The Firm can reserve the sign-off line for the person who signs and dates it.
