KKATC provided me with timely answering to pressing tax filing questions, and detailed links to resources for further support. I'm currently at a crossroads with a few financial planning decisions with tax implications, and the tool produced solutions backed by respected industry expertise. The perfect blend of tooling and professional insights that help people like me, with a limited understanding of tax procedures, the conviction and confidence to make the best decisions for my long-term future.

I have been on the force for years and never had time to figure out what I actually owed. Between the house and two kids I had real questions. KKATC gave me straight answers without the runaround. First tax tool I actually trusted.

Two kids, a home purchase in progress, and a lot of tax questions. KKATC answered them with actual IRS sources, not opinions. For someone who values accountability and precision, this is the tool I was looking for.

Nobody teaches you how to do your taxes in school. KKATC does. Moving out for the first time, first adult job, KKATC answered all of the questions I had. Easy to use, and reliable. Exactly what I needed.

I filed my taxes last night using the TurboTax app. The app had AI, but it wasn't helpful at all. Using your tool was the difference for me. It helped me confirm all my forms, and also the biggest tax breaks I can get. It also helped me get money back on the state, which last year I didn't get. 10/10.

Now Accepting Beta Organizations
KKATC™ Tax Foundation

We are building KKATC Tax Foundation with the organizations that will use it. Three founding nonprofit organizations are being onboarded now as honest beta stress testers. In exchange for real-world feedback, founding organizations receive grandfather pricing for life.

The tool covers federal 501(c)(3) and private foundation compliance, NY, NJ, and CT nonprofit exemption layers, UBIT, excess benefit transactions, PF distribution requirements, and state AG registration — all backed by IRS EO citations and reviewed weekly by a practitioner.

Public Accountability

Don't believe AI can be accountable? Try to break it.

Every error is logged publicly. Every stress test is signed by a human expert before publication. Every correction is hardcoded so the mistake cannot happen again. If you find an error we missed — the fix goes public and you get a month on us.
