An xAI executive recently suggested that taxpayers could “have Grok check your taxes,” sparking immediate concern among tax professionals. While Grok, the AI chatbot developed by xAI, is praised for its ability to analyze complex documents, experts caution that relying on AI for tax advice can lead to costly mistakes. This article explores the implications of this recommendation, expert reactions, and what taxpayers should consider during the 2026 tax season.
Grok’s Capabilities and the Executive’s Suggestion
Elon Musk and xAI have touted Grok’s ability to process and analyze lengthy, complex documents. In May 2025, Musk highlighted a user’s experience of having Grok analyze a 389-page tax bill, calling it “amazing” and noting that Grok can “instantly help figure issues in complex documents” .
Building on this, an xAI executive reportedly encouraged users to “have Grok check your taxes,” implying that the AI could assist with tax preparation. However, this suggestion has not been accompanied by any formal guidance or disclaimers from xAI regarding the limitations of Grok in tax matters.
Why Tax Experts Advise Caution
Inaccuracy and Hallucinations
Tax professionals warn that AI tools like Grok and ChatGPT often produce inaccurate or incomplete responses, especially when dealing with complex tax scenarios. A 2024 review by the Washington Post found that leading AI tax chatbots provided incorrect or irrelevant answers up to 50% of the time when asked complex tax questions .
Virginia La Torre Jeker, a tax law expert, emphasizes that AI tools may misinterpret nuanced international tax concepts, such as confusing the Foreign Tax Credit with the Foreign Earned Income Exclusion, or hallucinating nonexistent exceptions .
Real-World Consequences
Errors in tax filings can lead to serious consequences. La Torre Jeker notes that AI-generated mistakes could trigger IRS audits, penalties, and interest charges. For example, failing to report foreign assets correctly could result in penalties up to $10,000 or a 40% accuracy-related penalty on unpaid tax .
Similarly, Zacks reports that AI may misinterpret deductions—such as suggesting a full home internet deduction when only a portion is allowable—potentially leading to IRS scrutiny .
Declining Trust in AI for Tax Filing
A recent survey by Invoice Home shows that trust in AI for tax filing is declining. In 2026, only 37% of respondents said they would consider trusting AI over a tax professional, down from 43% in 2025 .
Tom Hood, CPA/CITP, CGMA, underscores that taxpayers should prefer a CPA using AI tools rather than relying on AI alone .
Privacy and Liability Concerns
Public AI chatbots may not safeguard sensitive financial data. Jason Wiggam, an attorney, warns that information shared with AI tools is not protected and may be used for learning purposes. The IRS also does not hold AI accountable for bad advice .
Ed Jenkins, accounting professor at Penn State, cautions that AI tools may make significant errors in tax calculations, raising both accuracy and privacy concerns .
Balancing Innovation and Oversight
While AI has limitations, it also offers potential benefits. The U.S. Treasury and IRS are exploring AI for taxpayer support, fraud detection, and operational efficiency. Governance measures are being implemented to ensure responsible use, including transparency and oversight .
AI can assist with organizing paperwork, performing basic calculations, and providing general explanations. But experts stress that these tools should complement—not replace—professional judgment .

Conclusion
The suggestion by an xAI executive to “have Grok check your taxes” highlights the growing intersection of AI and tax preparation. While Grok’s document analysis capabilities are impressive, tax experts uniformly advise against relying on AI for filing returns. Inaccuracies, privacy risks, and potential IRS penalties underscore the importance of professional oversight. AI can be a helpful tool—but not a substitute for expert judgment.
