Most tax software assistants combine a large language model with retrieval. When you ask a question, the system searches the company's help articles and tax content, may read context from your return, and writes an answer grounded in what it found. The actual tax calculation is not done by the language model. A deterministic rules engine, built and tested against the tax code, computes your tax from the answers you enter. Keeping that division in mind is useful. The engine is generally reliable for the inputs it receives, while the chatbot's advice about what to enter is the weaker link. Independent testing has borne this out. Journalists and reviewers who have put tax questions to assistants like TurboTax's and H&R Block's have found many answers wrong, incomplete or unhelpful. Assistants have also been built to decline or deflect certain questions, which lowers the risk of harmful advice but can leave users without an answer. Performance changes as vendors update models and content, so any single test is a snapshot. The errors resemble general chatbot errors, with one difference: the assistant appears inside a trusted product. Users may assume its answers carry the same guarantee as the calculations. Accuracy guarantees are defined in each product's terms, and you should read them rather than assume the chat is covered. Escalate to a human when your situation involves Schedule K-1s, rental property, self-employment with significant expenses, cryptocurrency, foreign income or accounts, a multi-state move, a home sale, a business purchase or sale, or an IRS notice. Escalate too whenever the assistant hedges or contradicts itself. Most major products sell access to credentialed preparers for review, and free help exists through IRS VITA and TCE sites for eligible filers.
