Secure by design.
Every number on the return is computed by a deterministic engine, never guessed by a language model. Your data is yours: never sold, never used to train generative AI. With Blanc Tax, trust is the default, not an afterthought.

The tax math is deterministic
Your return is computed, not generated. The same trial balance always produces the same numbers: no language model in the tax math, so nothing is guessed or hallucinated.
AI bookkeeping, only if you want it
You can let our engine categorize transactions and build journals for you. It's our own categorization system, not a third-party chatbot, and you review every suggestion before it counts.
How your data is used
We use your bookkeeping data to improve our own categorization over time. We never sell it, and we never feed it to a general-purpose or generative AI model to train on.
Immune to prompt injection in the return
Because the numbers are computed by a deterministic engine, instructions hidden inside a document can't change a single figure on the return.
Encrypted and isolated
Enterprise-grade encryption, isolated per client. Your data is unreadable without the key.
Defensible under examination
Every figure traces to a journal entry and a workpaper. Built to stand up to an IRS exam.
Expert in the loop
Nothing files itself. A qualified professional reviews, approves, and signs every return.
Your clients trust you with everything. We built Blanc Tax so you never have to think twice about trusting us with it.
