S-Corp taxes with two agents
Claude Code wrote Python scripts that compute the author's S-Corp tax forms from QuickBooks and bank data, while Codex reviewed the code.
Codex caught real errors, including a wrong Schedule L field mapping, and the author found their own 2025 mistakes.
Overview
How it was set up
QuickBooks data and bank statements in a private Git repo. Claude Code with Opus 4.6 writes the scripts. Codex with a high-reasoning model reviews them in multiple rounds.
Worth knowing
The source does not say whether a CPA reviewed the final filings. The author has used a CPA since 1996.
A prompt to start from
Review the tax-form scripts in [repo path]. Trace the data from [source JSON] through to the generated [CSV or form]. List findings ordered by severity, flagging any wrong field mappings.
