Generic AI tax tools assume a standard 1040 workflow. CPA firms and corporate tax departments don't work that way. Clarista lets you build AI tax prep that fits your client mix, your review workflow, and your jurisdiction expertise.
Tools like TaxGPT, Blue J, and CCH ProSystem fx AI features are built around standard tax forms. They handle 80% of cases competently. The remaining 20% — multi-state returns with apportionment, K-1 flowdowns, R&D credit calculations, international compliance — is where firms make their money and where generic AI breaks down.
Clarista lets you encode your firm's tax expertise into a custom AI. Your senior partner's review checklist, your jurisdiction-specific knowledge, your client-specific quirks — captured and applied automatically.
An AI assistant that reads source documents (W-2s, 1099s, K-1s, brokerage statements), extracts the relevant data, drafts the return, and surfaces the items most likely to need partner review. A tax research assistant trained on your prior years' positions, your jurisdiction's recent guidance, and your firm's risk tolerance.
Everything runs on your data. Client information never leaves your perimeter. Every AI decision is logged and traceable for audit defense.

Book a demo →Not in 2026. AI handles the document extraction, line-item drafting, and routine review — partners and senior staff handle judgment calls, complex positions, and client communication. Firms typically see 40-60% productivity gain on routine returns, freeing capacity for higher-margin advisory work.
On Clarista yes, because you encode the rules your firm uses. Generic AI tax tools struggle here because the rules are jurisdiction- and firm-specific. Your AI is trained on your prior years' multi-state returns and your senior reviewers' positions.
Yes. SOC 2 Type II, deploy on your firm's cloud, BYO LLM so model traffic stays in your contracted Anthropic/OpenAI/Bedrock account. No client data flows through Clarista's infrastructure.
