Ask an AI Accountant 2.0 is Keeper’s AI tax Q&A experiment for answering questions about U.S. individual tax law. The most important thing to know in 2026 is that Version 2.0 is no longer being updated. Keeper now directs users to create an account and use its newer AI tax assistant, which can be tailored to a user’s situation.

That makes V2 more useful to review as a demonstration of how Keeper approaches AI-assisted tax guidance than as its current flagship assistant.

The V2 system uses GPT-4o alongside tax-specific retrieval. Keeper says it incorporated federal U.S. tax codes, state tax codes, and IRS announcements from the previous ten years, then built a retrieval system designed to find relevant tax material before producing an answer.

A general AI assistant can discuss taxes, but tax questions expose one of the biggest weaknesses of broad language models: a confident answer can still be wrong.

Keeper tried to reduce that problem by grounding V2 in tax material rather than relying only on what the underlying model already knew. Its retrieval process searches tax-law embeddings related to the question and uses the relevant information when generating a response.

This makes the tool most interesting for focused questions such as filing status, deductions, tax treatment of income, self-employment rules, or unusual personal tax situations.

It is less suitable for simply asking, “How much tax will I owe?” when the calculation requires many assumptions.

One of the better parts of the project is that Keeper published a review system around the AI’s answers.

Responses were periodically evaluated by tax professionals, including CPAs, IRS Enrolled Agents, and other qualified reviewers. Previously answered questions can show whether a professional marked the response correct or incorrect, and reviewed answers may include comments from the grader.

Keeper reports 96% accuracy for the AI compared with 94% for human tax professionals in its evaluation. V2 also scored 88% on a sample of questions from Part 1 of the Enrolled Agent exam.

Those numbers need context, however. Keeper excluded excessively ambiguous and contentious questions from grading. Its published accuracy evaluation also covered English-language questions about U.S. individual tax law, not corporate tax or broader financial advice.

So the benchmark is useful, but it shouldn’t be interpreted as a 96% guarantee for every tax question.

The newer Keeper product goes beyond standalone tax Q&A. Keeper currently combines tax assistance with expense tracking, deduction detection, tax filing, and access to tax professionals. Its help documentation says users can interact with an AI tax assistant through the Ask tab and can also receive help from tax-assistant staff.

For self-employed users, Keeper can also scan linked financial transactions for potential deductions and carry tracked deductions into its tax-filing workflow. That broader context makes the current assistant more useful than V2’s isolated question-and-answer format.

Ask an AI Accountant 2.0 is most useful for:

• Understanding unfamiliar U.S. individual tax concepts.
• Getting a quick explanation of deduction rules.
• Exploring self-employment and freelance tax questions.
• Checking how a particular source of income may be treated.
• Reviewing previously graded tax questions.
• Learning what information you may need before speaking with a tax professional.

Keeper explicitly lists several weaknesses in V2.

Some state and city tax details were not fully covered. Complex calculations involving many reasoning steps could cause problems. Keeper also notes that the system could be overly conservative because it followed the underlying tax rules closely even in situations where real-world practice might be less strict.

There is also the larger issue shared by every AI tax assistant: a tax answer can depend on facts the user leaves out. Filing status, jurisdiction, income sources, dates, business structure, and exceptions can change the result.

Keeper therefore labels the tool as educational and says its responses do not constitute tax, accounting, or legal advice.
