Do bookkeeping and tax prep from a folder of documents
I used Claude's Cowork to do my bookkeeping and tax prep this year. Task: The user pointed Claude Cowork at a local 'Taxes' folder containing mixed source documents like W-2s, 1099s, and bank statements. Cowork organized these files into subfolders, generated a Context.md briefing, and created a master bookkeeping spreadsheet with income and expense tabs. The workflow also produced a tax summary with refund projections and an accountant briefing, while flagging missing data and discrepancies for human review.; tools: Claude Cowork. Human role: The original post does not say how a person stayed involved.; limitations: Prerequisites include having all source documents (W-2s, 1099s, bank CSVs) available in a single folder. The workflow relies on Claude Cowork's ability to access local files and process mixed formats. Human verification is critical for financial accuracy, as the tool may miss context or misinterpret ambiguous data. The source does not detail specific error rates or costs..

Overview
I used Claude's Cowork to do my bookkeeping and tax prep this year.
Workflow
The user pointed Claude Cowork at a local 'Taxes' folder containing mixed source documents like W-2s, 1099s, and bank statements. Cowork organized these files into subfolders, generated a Context.md briefing, and created a master bookkeeping spreadsheet with income and expense tabs. The workflow also produced a tax summary with refund projections and an accountant briefing, while flagging missing data and discrepancies for human review.
Reported result
The author reported saving 6-8 hours of manual work and producing more organized outputs than previous attempts. Cowork successfully handled messy formats, caught numerical discrepancies, and generated a checklist for the tax appointment. No independent verification of the time savings or accuracy of the financial calculations was provided in the source.
Human role
The original post does not say how a person stayed involved.
Limitations
Prerequisites include having all source documents (W-2s, 1099s, bank CSVs) available in a single folder. The workflow relies on Claude Cowork's ability to access local files and process mixed formats. Human verification is critical for financial accuracy, as the tool may miss context or misinterpret ambiguous data. The source does not detail specific error rates or costs.
Try it
Act as a financial assistant using Claude Cowork. I have a folder named [replaceable_folder_path] containing my tax documents (W-2s, 1099s, bank CSVs, mortgage docs). First, organize these files into subfolders by year and category. Then, create a Context.md file summarizing my filing status, income sources, and key numbers. Next, build a master bookkeeping spreadsheet with tabs for income, expenses, and write-offs. Finally, generate a one-page accountant briefing and a checklist of missing documents. Before finalizing, show me a sample of the organized structure and the Context.md draft for my approval. Do not proceed to full spreadsheet generation until I confirm the initial organization is correct. If any documents are missing or numbers conflict, flag them explicitly in the checklist.
