open-tax

plugin Software development

Free, open-source US federal tax preparation assistant for Claude Code. Drop your W-2s, 1099s, and crypto exchange CSVs into the workspace — Open Tax parses them, computes your federal tax liability with full bracket breakdowns, handles capital gains (Form 8949), backdoor Roth IRA (Form 8606), excess Social Security tax, and crypto staking income. It runs sanity checks, suggests missed deductions, and exports ready-to-import files for FreeTaxUSA or TurboTax. 100% local and private — no tax data ever leaves your machine. Zero pip dependencies — Python stdlib only.
