Check a tax organizer and compare it with last year
A person used Claude in Chrome and Claude Code to extract organizer fields, complete them from tax records, and catch a missing deduction in the prior return.
- What they did
- The CPA’s organizer was trapped in a locked web app, so Claude in Chrome went through the PDF in short stretches and converted each page’s prompts into JSON. Claude Code then matched those prompts against the person’s tax paperwork, entered the answers it could verify, and marked holes such as a daughter’s SSN. Claude in Chrome copied the finished material back into the organizer in small sets of pages, and the person reviewed each one before it moved ahead. In another pass, Claude examined the 2024 return alongside the supporting documents.
- How it went
- After review, the organizer was completed correctly. The 2024 review turned up a goodwill depreciation deduction that had been missed, and the CPA agreed it belonged on the return. Claude initially said everything checked out even though it had not actually gone through the source documents.
- Tips
- Breaking the work into short batches helped when Claude in Chrome lost track and hit a usage cap. Ask it directly whether it has opened every file and whether any items remain unresolved before you trust its answer.
Try it yourself with Claude in Chrome
Open my tax organizer in [URL] and turn each question into a structured checklist with sections and fields. Use the files in [folder] plus [prior-year return file] to supply answers, mark any blanks you cannot verify, and compare everything against the prior return to spot changes or omissions. Do not invent values; leave unknowns empty and gather them in a separate list. Before any submission, sending, deletion, or other irreversible action, stop and ask me to approve the final version. Also confirm whether you have reviewed every relevant file, and name anything you still have not checked.
Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
