How a return flows through the platform
01
Upload return
CPA uploads the PDF. Browser extracts text and redacts SSNs / EINs / account numbers locally — raw bytes never leave the browser.
02
AI audit
Sonnet 4 runs the redacted text against the full IRC catalog, deduction master, and Tax Court precedents. Cites every position.
03
Two-tier review
Staff toggles each finding (apply / reject / needs info). Partner ratifies. Audit log captures every click for SOC 2.
04
Deliver
Download a branded PDF report and send it to your client however you already send things. We never email your clients.
Beyond the tax audit

The same platform generates 9 more deliverables your firm can bill for — Business Setup Plans, Entity Restructuring Memos, Real Estate Tax Briefs, Funding Roadmaps, Marketing Strategies, and full Business Plans.

Built for compliance from day one
  • Zero-knowledge architecture
    PDFs never leave the CPA’s browser. Server sees only redacted text + a SHA-256 fingerprint.
  • §7216 consent gate
    Audit cannot run until signed client consent (Rev. Proc. 2013-14 wording) is on file.
  • Two-tier review
    Staff proposes, partner approves. No finding ships without sign-off.
  • Append-only audit log
    Every read of customer data logged. Owners get a queryable view.
  • MFA mandatory
    AAL2 required before any audit or deliverable. TOTP enrollment per user.
  • Firm-only access
    No client portal. The CPA stays the gatekeeper. Cleaner UPL / Circular 230 posture.
