Open Tax

plugin

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

Works with: Claude Code (native)
native: this artifact type is that client's own format

Security audit

Not scanned yet. We audit npm-published capabilities for known advisories, install-time scripts and permission surface; this one has no npm package we can resolve, or has not reached the queue.

You searched for one. Check the rest of your stack:

npx tashan-cli doctor

Reads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.

Everything on this page is public evidence and free. What it cannot know is whether you run this — check your whole config, free, in the browser. tashan Pro adds the series behind each row and names a replacement for anything dying.

Already running this? Check your whole config — free, in your browser, nothing installed. Or npx tashan-cli doctor locally, which sends nothing at all.
