The partner-level expertise.
Without the partner-level price.
In my corporate tax career I sat across the table from Big 4 partners, C-suite executives, and IRS agents. At that level, a small business owner never gets in the room. KKATC exists to change that. Fully virtual. Research powered by KKATC Flow. Human accountability on every return.
Got a letter from the IRS?
That is exactly what we are here for.
The gap that should not exist. But does.

12 years.
You get all of them.
Konstantin Koretskiy spent 12 years in Fortune-level corporate tax across Financial Services, Media and Entertainment, and Advanced Manufacturing. He identified and executed on $32.6M in federal tax reductions, including a $23M IRC §45X Advanced Manufacturing Production Tax Credit claim built before most corporate tax teams had finished reading the IRA.
He built KKATC because the clients who need that level of expertise most are the ones who can never afford it at a firm. That changes here.
Tax Desk and Corp Desk run the research and workpapers behind every engagement. Every answer cites its IRC section. Every position is defensible.
The KKATC Watchdog publishes every AI tax error we find — including our own. You can read our corrections log before you hire us.
No office means lower overhead means your bill reflects expertise, not square footage.
The IRS does not wait.
Neither should you.
15 minutes. No commitment. Ask anything.
