AlgoTax is the evidence layer that sits behind your filing software — built for working CPAs and firms, not DIY filers. Every calculated number on the return carries a line-by-line provenance trail: click any figure to see the source documents, the transactions that fed it, the calculation method, and which AI models were involved.
Three competing AI models — from Google, Anthropic, and OpenAI — extract every uploaded document in parallel. When two models disagree on a value by more than 1%, the document is flagged for CPA review instead of being silently averaged, so no output is treated as more certain than it actually is.
AlgoTax includes full books — chart of accounts, journal entries, trial balance, bank reconciliation, income statement and balance sheet — with the same provenance on every dollar. Pair it with AlgoBooks for day-to-day bookkeeping. The CPA pilot is opening via waitlist for fall 2026.
