Corporate income tax · auditable · AI-native
From trial balance to Form 1120.
Blanc Tax prepares your corporate income tax return from the general ledger and trial balance: a filing-ready Form 1120, every schedule, every book-to-tax adjustment, every workpaper. One platform, end to end.
A single reviewer does the work of a team. Weeks of prep become a matter of minutes. Every figure on the return traces to its journal entry, defensible under examination.
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
