From the makers of Citation Safe
Tax Cite Safe: verify IRC sections and Treasury Regulations before you file.
The same deterministic, no-LLM-in-the-loop existence check that powers Citation Safe, pointed at tax authority. We check every IRC section and Treasury Regulation citation in your document against the actual public source — live, not from a cached table — and tell you exactly what we found.
Checked live against Cornell Law's Legal Information Institute.
Checked live against the eCFR's official versioner API.
Checked against CourtListener's Tax Court index, with a case-name cross-check whenever a case name accompanies the cite. Lower-confidence than case law — a citation whose claimed name does not match the record comes back UNCONFIRMED, never VERIFIED.
Honest coverage note
Revenue Rulings, Revenue Procedures, IRS Notices, and Private Letter Rulings are recognized by our parser but marked UNCONFIRMED — OUTSIDE COVERAGE today. We have not found a reliable free structured public source for these yet, and we would rather tell you that than fake a check.
Why a separate vertical, same engine
Tax citation coverage is a different data problem than case law, so it ships as its own data adapter on the same verification engine (see /quality for how Citation Safe's engine works) rather than a bolt-on. Free tier verifications are shared with Citation Safe: 3/month, no card required.
