THE KKATC® BELIEFAI didn’t replace us.
AI didn’t replace us.
We stopped leveraging it.
For most of human history every generation faced the same choice: adapt to a new technology or fall behind it. The printing press. The calculator. The internet. Every time, the people who leveraged the technology first won.
AI is no different. Except this time the technology thinks.
KKATC® was built on a different belief. AI is not a replacement for human judgment. It is the first technology in history capable of being held to the same standard as a human. It can cite its sources. It can publish its mistakes. It can be audited. It can be made accountable.
The model researches. I decide. The Watchdog proves it.
— Konstantin Koretskiy, Founder
THE AI
Reads the IRC, OBBBA, and 19 state codes in real time. Surfaces applicable law. Flags risk. Never sleeps.
THE HUMAN
12 years in corporate tax. Consulting work is reviewed by KKATC before it reaches you.
THE PROOF
A public registry of AI tax errors — including ours. Every correction published. Trust is not a marketing line.
The question is not whether AI belongs in tax practice. It does. The question is whether the AI you are using can defend its answers. Generic AI tax wrappers give you information. KKATC® gives you a position you can defend — backed by IRC authority, IRM examination procedures, a three-level review chain, and a public error registry that publishes every mistake including our own.

KKATC® Cards: Reseller Workflow
Every sale. One ledger.
Import your eBay sales or a CSV into KKATC® Cards, and each sale is recorded against its card’s cost basis. Come tax time, your Schedule C is already built: IRC §471(c) cost basis, an XLSX workbook with authority citations. The optional KKATC® planning session is a separate consulting service from KKATC, booked through KKATC Consult; it is not part of the software.

Modern consulting. Affordable by design.
AI handles the research load that used to require a senior associate billing at $400/hour. You get the judgment layer — the part that actually requires 12 years of corporate tax experience — at a fraction of what a Big 4 firm charges. That is not a discount. That is a structural cost advantage built into every engagement.
AI accelerates. Humans decide.
KKATC® analyzes your situation against current law including all OBBBA amendments. Consulting work is reviewed by KKATC before it reaches you.
Packages, not hourly billing.
CP2000 responses, amended returns, and planning sessions are fixed-scope engagements. No invoice surprises. No retainer.
Corporate tax credentials. Small business access.
12 years across Financial Services, Media & Entertainment, and Advanced Manufacturing. Available without a Big 4 relationship.
