JJ Englert describes giving Claude Cowork a local tax folder containing forms, bank statements, mortgage documents and business records. The agent organized the source documents into year and category folders, then created a Context.md briefing so later work could use filing information, entities, key figures and unresolved questions consistently.
Cowork used bank CSVs to build a master bookkeeping spreadsheet with income, expenses, write-off analysis and home-office material. It also produced a tax summary, highlighted discrepancies and missing documents, and assembled a checklist for the author's appointment. A one-page accountant briefing was the final handoff artifact.
The author reports saving six to eight hours and finding the output more organized than his previous preparations. Those are personal estimates, not an independent audit of the calculations or deductions. The source describes preparation for a tax professional, not an autonomous filing or verified refund. The author supplied the previous year's finalized return as a reference and retained the accountant appointment as the next review step. The practical outcome is a structured document and spreadsheet package with open questions made visible before filing decisions.
