Money, Bills & BenefitsDone with Claude in Chrome, Claude Code
Fill in a tax organizer and review last year's return
Claude in Chrome captured the organizer's fields and entered data, Claude Code filled them in, and Claude reviewed the prior return; it sometimes claimed work was done without the info.
- What They Did
- The CPA's organizer PDF was locked inside a web app, so Claude in Chrome listed its fields as JSON, a few pages at a time. Claude Code filled in the values from his tax documents and flagged missing items such as a daughter's SSN. Claude in Chrome then entered them three pages at a time, and he checked each page. Separately, Claude reviewed the 2024 return and its source documents.
- How It Went
- The organizer was filled in correctly after review. Claude's 2024 review found a missed goodwill depreciation deduction, which the CPA confirmed. Claude first said everything looked fine without reading the source documents.
- Worth Knowing
- Claude in Chrome lost track on long runs and hit a usage limit. Use plan mode, and ask it outright whether it read every file and whether anything is missing.

Open my tax preparer's online organizer at [URL] and list every field and section it asks for. Then fill in the answers using the documents in [folder], and compare it with my prior-year return at [file path] to flag anything that changed or looks missing. Never fill in a field you don't have data for; leave it blank and list it for me, and pause before submitting anything.
