- Extracts taxpayer data from source forms (W-2, 1099, K-1) and pins each value to its bounding box on the page — so the number carries its provenance from the first hop.
- Datapoint provenance
The governed Tax AI that proves every number.
A 4-agent pipeline — intake → deduction-finder → return-reviewer → compliance-check — prepares, reviews, and compliance-checks returns. Unlike any horizontal copilot, every deduction and figure traces to its source form in a tamper-evident ledger you can hand to an auditor.
Aligned with IRS Circular 230 · SOC 2 · EU AI Act · high-risk: bias monitoring
A preparer is responsible for every number — so the AI must be too.
IRS Circular 230 makes the practitioner accountable for diligence and accuracy; an AI that quietly hallucinates a deduction or paraphrases a figure is a liability, not a productivity tool. Cortex grounds every figure to the source form, scores accuracy against a gold eval suite, and seals each return so the number on the line can always be traced back to the box on the page.
A 4-agent pipeline — each step grounded and gated.
Every agent is a registered, identity-bound actor with allowed models and actions; each hands off through the Action Fabric and seals its output into the ledger.
- Identifies eligible deductions and credits grounded to the extracted facts and IRS rules — citing the source figure for each, never inventing one.
- Grounded RAG
- Reviews the assembled return against the gold eval suite (faithfulness, citation coverage, safety) and flags discrepancies for a human in ≤ 30 minutes.
- Observability & evals
- Runs the Circular 230 diligence checks and bias monitoring as Policy-as-Code, blocking sign-off if a figure can't be traced to its source.
- Policy-as-Code
- Every figure links to its source form, page, and bbox in a hash-chained ledger — click a number, see exactly where it came from, verify it wasn't altered.
- Trust Ledger
97% accuracy. 95% citation coverage. ≤ 30-minute review.
These aren't aspirations — they're the measured targets of the @cortex/pack-tax gold eval suite. Every figure cites its source form, the reviewer turns a return in under thirty minutes, and the whole thing ships in your own environment with the evidence pack attached.
- 97% accuracy measured against a gold evaluation suite — not a vibe check
- 95% citation coverage: every figure traces to its source form, page, and bbox
- ≤ 30-minute review turnaround with discrepancies pre-flagged
- EU AI Act high-risk posture: bias monitoring and human review built in
The verdicts you'll see in the demo.
Challenge the pipeline and it fails closed — an uncited number never makes it onto a signed return.

Model the domain
Map the work to typed ontology objects — Taxpayer, Return, Form, Deduction, Finding — with restricted fields like ssn / ein locked at the property level.
- 02
Encode the rules
Translate the obligations above into Policy-as-Code and Action Fabric approvals — the gates fail closed, returning a precise code, not a guess.

Prove the outcome
Every run lands in a hash-chained Trust Ledger with signed receipts and 10-hop provenance — a record you can hand the regulator.

Trust Center
Map the pipeline to Circular 230, SOC 2, and EU AI Act high-risk controls.
Built for the diligence Circular 230 puts on the practitioner.
The grounded pipeline, gold evals, sealed ledger, and bias monitoring map directly to the diligence, accuracy, and AI-management-record controls a tax practice reports against. Aligned with — never claiming certification you don't hold.
AI agents for tax — questions, answered.
How does Cortex Tax AI prove a number is correct?
Each figure is pinned to its source form, page, and bounding box at intake, carried through the pipeline with a value hash, and sealed into a hash-chained ledger. Click any number to see exactly where it came from, and verify it wasn't altered after extraction.
What is the Tax pack's published SLA?
97% accuracy measured against a gold evaluation suite, 95% citation coverage so every figure traces to its source form, and a review turnaround of 30 minutes or less.
How is the Tax AI a 4-agent pipeline?
Intake extracts and grounds the data, deduction-finder identifies eligible deductions, return-reviewer checks the assembled return against the eval suite, and compliance-check runs Circular 230 diligence and bias monitoring before sign-off.
Does this satisfy EU AI Act requirements for high-risk AI?
Cortex treats tax preparation as high-risk: it adds bias monitoring, mandatory human review, grounded outputs, and a sealed AI-management record. It is built for alignment with the EU AI Act — Cortex does not assert certification you don't hold.
