Why KKATC
Other AI tax tools give you an answer. KKATC gives you a position you can defend.
Any developer can wrap Claude or GPT-4 around a tax question and ship a product in a weekend. What they cannot ship is twelve years of Fortune-level corporate tax experience, a working knowledge of how IRS examiners actually conduct Schedule C audits, and a card collection that made the tax problem personal. That gap is not a feature. It is the product.
The problem with AI tax wrappers is not that they are wrong sometimes. It is that you cannot tell when.
A generic AI tax tool has no accountability layer. It has no authority citations. It has no published correction history. It has no practitioner behind it who signs their name to the output. When it is right you feel confident. When it is wrong you find out at the worst possible moment — during an audit, when a penalty notice arrives, when your CPA has to unwind months of decisions built on a bad answer.
The IRS Office of Professional Responsibility released guidance in June 2026 mapping six Circular 230 duties to AI use in tax practice. The requirement is clear: every AI output used in a tax context must be reviewed against authoritative sources before it reaches a client or a filing. Generic wrappers have no mechanism for this. KKATC was built around it.
Prose answer, no citations, no way to verify.
Every answer cites its IRC section, its IRM examination procedure, and its state authority. Not because it sounds professional. Because if you ever face an IRS examiner, the answer on your screen needs to hold up to the same scrutiny the examiner is applying.
One model for every question regardless of complexity or stakes.
Four tiers. Simple federal questions route to a fast efficient model. Multi-state OBBBA questions route to the most capable model available. The model matches the stakes.
| T1 | Haiku | Routine federal questions |
| T2 | Sonnet 5 | State-specific, OBBBA, complex |
| T3 | Opus 4.8 | High-stakes paid path |
| T4 | Fable 5 | Apex — highest stakes determinations |
Model generates output, output ships to user.
Before any output reaches a client it passes three independent review passes. Level 1 generates. Level 2 verifies every citation and checks regulatory currency. Level 3 validates position sustainability and audit risk. A REJECT at any level disables delivery. This is the Big 4 quality control framework implemented in software.
Trained before the One Big Beautiful Bill Act of 2025. Giving wrong answers on §30D, §25C, §25D, the tips deduction, the overtime deduction, and dozens of other provisions with no mechanism to know it is wrong.
23 rules hardcoded in KKATC Core Rules v2.2.3 that override the model's training data on every OBBBA question. When the law changes KKATC changes with it.
No published error history. No accountability trail. No mechanism for admitting mistakes.
Every AI tax error KKATC finds — including errors made by KKATC Tax — is published at kkatc.com/watchdog. 12+ published corrections. No generic AI tax tool publishes its own mistakes. KKATC does because trust is the product.
Built by a developer. No tax credential. No audit experience. No understanding of how IRS examiners actually conduct Schedule C examinations.
Built by Konstantin Koretskiy. 12+ years of Fortune-level corporate tax experience. PTIN P03475545. Someone who went through a real Schedule C audit for a real card reselling business and built the documentation framework inside the tool he created.
Using an AI tax tool without a practitioner behind it is not just a bad user experience. It is a compliance risk.
Under IRC §6662 a taxpayer can be assessed a 20% accuracy-related penalty on any underpayment attributable to negligence or disregard of rules and regulations. Relying on an AI tool that gives wrong answers without the user knowing is not a defense. It is the definition of negligence.
Under Circular 230 §10.22 any practitioner who uses AI in tax practice must thoroughly review every AI-generated output before it reaches a client or a filing. A generic wrapper with no review chain puts the practitioner at personal disciplinary risk.
KKATC is built to satisfy both standards. The three-level review chain is the §10.22 compliance mechanism. The IRC authority citations are the §6662 defense. The Watchdog is the public record of due diligence.
