Arc & Ledger Tax Tools is a set of free, read-only tax calculators and explainers built by an Enrolled Agent enrolled to practice before the IRS. Decode an IRS notice, check FBAR/FATCA obligations, compare LLC vs S-Corp, estimate quarterly taxes and IRS penalties, check ITIN eligibility, compare US formation states, and more. Every answer is general information (not tax advice) and can hand you off to a human Enrolled Agent if you want personal help. Especially useful for US small businesses, international founders, and anyone who just received an IRS letter. No account or login required.

Concordance

@matharrismma

Language models generate; Concordance verifies. The verify tool checks a claim deterministically (no model in the loop) and returns HOLDS / BROKEN / INCOMPLETE with the worked reasoning and a sealed receipt (content_hash + cite_url) that re-fetches byte-identical or not at all. Also: ranked search over an ~11k-record library, seal_fetch to re-verify any receipt, redact to strip PII before text travels, and a sealed connection graph. Runs sovereign/offline too (stdlib-first Python). A public false-positive benchmark covers every domain: the engine has never sealed a falsehood. 38 tools live; remote endpoint at https://narrowhighway.com/mcp.
