AI tax software a firm can sign.
AI tax software is only as good as what your firm can defend. A corporate return is not a draft to be eyeballed; it has to stand up to examination. Blanc Tax is AI-native where it helps and deterministic where it counts: the tax math has no language model in it, the same trial balance always produces the same return, and zero client data is sent to third-party LLMs.
What to demand from AI tax software
Deterministic tax math
The same trial balance always produces the same return. Computation, not generation: there is no language model in the tax math.
Zero data to third-party LLMs
Your clients' books are never sent to an outside AI provider, and never train a model. Yours or anyone else's.
Traceable, not plausible
AI that drafts a number you cannot trace is a liability. Every figure here traces to a journal entry and a workpaper.
Corporate scope
Built for return preparation: Form 1120, 1120-S, and 1065, every schedule, Schedule M-1 and M-3, and the workpapers behind them.
Excel-native
Works with the general ledger, workbooks, and trial balance your firm already uses. No migration.
Expert in the loop
Nothing files itself. A qualified preparer reviews, approves, and signs every return.

AI tax software: FAQ
What is AI tax software?
AI tax software applies machine intelligence to tax work. For a CPA firm preparing corporate returns, the bar is higher than a chatbot: the tax math must be deterministic and every figure traceable to a workpaper, because the return has to stand up to an IRS examination, not just read plausibly.
Is AI tax software accurate enough for corporate returns?
It depends entirely on the architecture. Software that generates numbers with a language model can hallucinate. Blanc Tax computes the return deterministically: the same trial balance always produces the same Form 1120, and every figure traces to a journal entry and a workpaper.
Does Blanc Tax send client data to AI models?
No. Zero client data is sent to third-party LLMs, and zero data trains any model. The tax math runs on a deterministic engine, encrypted and isolated per client.
What tax software do CPA firms use for corporate returns?
Most firms stitch together a patchwork: trial-balance software, workpaper apps, reconciliation tools, and spreadsheets around a filing suite. Blanc Tax consolidates that work into one platform: trial balance in, a filing-ready return with every schedule and workpaper out.
The throughput of a team, defensible to the last figure.
