Messy PDFs.
Unclear rules.
Back-and-forth emails.
You see the final numbers,
but never understand:

You understand:
We explain how taxes, benefits, and thresholds actually work — so you can see what changed and what it means next.
After meeting with thousands of tax advisors, one issue kept appearing again and again.
The numbers were there.
The software worked.
But the why was missing.
Advisors were handed results without context. Their clients were even further removed not because the questions were bad, but because the systems were built for tax pros.
Most tax software is designed for compliance not explanation. Professionals are paid to file not to explain how rules interact over time.
So NotTaxAdvice does something different.
You don’t need insider knowledge.
You don’t need to be a tax professional.
You just need clarity.




Deterministic rules. Explicit assumptions. Human review. Explanations that hold up under inspection.
The goal isn’t prediction or optimization it’s understanding. You should be able to see how an outcome was produced, step by step, using rules that are explicit and assumptions that are visible.
Rather than presenting a single result, the system shows the sequence of interactions that led there. You can trace how inputs flow through the rules, how thresholds are applied, and how different components of the system influence one another over time.
If a number changes, you can see exactly what moved which threshold was crossed, which rule was triggered, and which interactions actually mattered. Nothing is hidden behind a score or a black box.
That visibility makes it possible to reason about outcomes rather than simply accept them. The purpose is not to tell you what to do, but to make the mechanics legible so decisions are made with context instead of guesswork.
