Our verdict on TaxBert
TaxBert is an AI-assisted tax research tool for tax professionals who need federal and state answers in a browser. It combines natural-language questions with follow-up conversations, source-backed answers, and access to TheTaxBook content. The product is included with the WebLibrary Plus subscription rather than sold as a standalone service, making it a fit for practitioners who want AI research alongside a broader tax reference library.
Pricing is straightforward: WebLibrary Plus with TaxBert costs $429 per user per year. An Additional WebLibrary Plus User costs $199 per user per year and provides a separate username and password with access to the subscription. A five-day free trial is available. The paid subscription includes federal and state research content, court cases, government documents, current-law updates, web access, and the TaxBert AI assistant. That combination makes the entry price more useful for buyers who need both conversational research and a searchable reference collection.
Its strongest functional advantage is the breadth of research and follow-through in one web workspace. Users can search the library, recall and search prior conversations, draft client emails, letters, and announcements, and work with bookmarks, history, prior-year archives, PDF printing, and emailing. Coverage spans 51 jurisdictions, while the case-law database and current-law updates support research beyond basic question answering. TaxBert is a sensible choice for tax professionals seeking affordable U.S. federal and state research with AI assistance. Buyers seeking a standalone AI product, integrations, or a non-web deployment should choose another option.
