From trial balance
to Form 1120.
Blanc Tax turns your general ledger, workbooks, and final trial balance into a complete Form 1120, every schedule, every book-to-tax adjustment, every workpaper. One platform, end to end.
Computed, never guessed.
AI is probabilistic. Your tax numbers should not be. Blanc Tax is AI-native, yet every figure on the return comes from a deterministic engine, never a language model. The productivity of AI, without the risk.
How we keep your data safe0 data sent to third-party LLMs
Blanc Tax runs on a deterministic engine, not a language model. Your clients' data never leaves for a third-party LLM or AI provider.
No hallucinations
It computes, it never guesses. The same input gives the same answer, every single time.
No prompt injection
There is no language model to trick. Content hidden inside a document cannot steer the outcome.
Auditable by construction
Every figure traces to its journal entry and workpaper. Explained, challengeable, defensible under examination.
Everything the corporate return demands.
One platform, end to end. Retire the patchwork of tools in between.
4x your junior accountants

One platform, end to end
Journal entries, trial balance, book-to-tax, schedules, and workpapers: the entire corporate return in one system. Retire the patchwork of tools you stitch together and re-key between today.
