The Rise of AI Tax Preparation: A Double-Edged Sword for American Taxpayers

AI Adoption in Tax Filing Surges Despite Growing Concerns

The way Americans approach tax season is undergoing a dramatic transformation. More and more people are turning to artificial intelligence tools like ChatGPT, Claude, and Elon Musk’s Grok chatbot to help navigate the often-confusing world of tax preparation. According to recent polling from Adobe, about 26% of Americans are now using AI to file their 2025 tax returns—a significant jump from just 11% the previous year. This surge in adoption reflects both the growing comfort with AI technology and the desperate search for assistance in understanding our increasingly complex tax system. Elon Musk himself has promoted this trend, posting on X (formerly Twitter) that his Grok AI chatbot “can help with your taxes,” and highlighting a case where someone claimed the tool helped boost their tax refund by $1,400. However, beneath this seemingly helpful technological advancement lies a minefield of potential problems that could cost taxpayers dearly.

Understanding the Fundamental Limitations of AI in Tax Preparation

While AI has indeed become integrated into professional tax preparation software, there’s a critical difference between purpose-built tax systems and general-purpose chatbots. Caroline Bruckner, a tax professor at American University’s Kogod School of Business, emphasizes that while AI is not new in tax preparation—it’s built into professional tax software that generates returns—the consumer-facing chatbots that have become ubiquitous carry significant risks. The fundamental problem is that AI on its own simply isn’t capable of preparing an accurate tax return. These large language models draw information from vast databases of online content, including government websites like IRS.gov, which contain enormous amounts of outdated information that doesn’t reflect current tax law. The IRS website must maintain historical information from 2020 alongside current 2025 guidance, but tax laws and tax breaks have changed dramatically over those five years. When someone asks a general question about deductions, the AI might pull from outdated sources and present information about deductions that are no longer applicable or that have been significantly modified. Recent changes under the Republicans’ “one big beautiful bill act” (OBBBA) may not yet be reflected in AI-generated responses, creating a dangerous gap between the advice given and current reality.

Where AI Can Actually Help with Tax Preparation

Despite the warnings, experts acknowledge that AI tools do have legitimate and useful applications when it comes to tax preparation, as long as they’re used appropriately. One of the most valuable uses is asking AI to explain complicated tax concepts without providing any identifying personal information. For example, if you’re a worker who earns gratuities, you can ask an AI chatbot, “What is the no tax on tips deduction?” and get a reasonably clear explanation. As Bruckner notes, AI can be excellent at translating complicated tax concepts into plain English, making the tax code more accessible to ordinary people who don’t have accounting degrees. Lisa Greene-Lewis, a tax expert with Intuit (the maker of TurboTax), agrees that it’s perfectly fine to use free, publicly available AI programs for general education purposes around tax concepts—learning what terms mean, understanding basic principles, or getting a general overview of how certain provisions work. However, she draws a clear line when it comes to actually filing returns. There’s a significant difference between these general-purpose AIs and specialized TurboTax AI models, which have been trained on hundreds of millions of actual tax returns and financial data points, are continuously updated with the latest tax code changes, and are validated by human tax professionals. The key is understanding that AI should be a learning tool, not a replacement for proper tax preparation software or professional guidance.

The Serious Risks and Pitfalls of Relying on AI Chatbots

Tax professionals are sounding the alarm about multiple serious pitfalls that come with relying on general AI chatbots for tax preparation. Mark Gallegos, a tax accountant at Porte Brown accounting firm, makes it clear that while AI might potentially help outline changes to the tax law under recent legislation, it’s absolutely no substitute for working with an experienced tax professional or tax-specific software. The technology simply isn’t there yet—AI won’t actually prepare your tax return correctly at this moment, and we might get to that point in the future, but we’re definitely not there today. Danny Werfel, who served as IRS commissioner from 2023 to 2025, points out that ChatGPT and similar AIs are not specific to the realm of taxes and haven’t been tested for accuracy in this specialized domain. He issued a particularly important warning: never feed sensitive personal information to these models. Users should be extremely wary of using AI for tax purposes and should seek assurances that their information won’t be harvested or shared for commercial purposes. The privacy implications are enormous—once you’ve entered your financial details into a chatbot, you have no control over where that information goes or how it might be used. This security concern alone should give taxpayers serious pause before typing their income, Social Security numbers, or other sensitive data into a general-purpose AI tool.

The Problem of Interpretation and Accountability

One of the most insidious problems with using AI for tax preparation involves the technology’s difficulty in interpreting between outdated and current information, particularly because the IRS’s own materials can be misleading. Julie Siegel, former deputy chief of staff at the Treasury Department, explains that large language models don’t truly understand how a certain set of facts apply to your particular tax situation. They’re pattern-matching machines, not reasoning entities with genuine comprehension of tax law. The IRS materials themselves can confuse AI systems in dangerous ways. For example, an IRS form with a headline reading “No tax on overtime” might cause an LLM to conclude that you don’t owe taxes on any overtime pay whatsoever, which would be completely inaccurate. Even when an LLM is looking at an authoritative source like the IRS, it may mistakenly calculate no tax at all on overtime when, in reality, complex calculations and exemptions apply. The most critical point Siegel raises is about accountability: at the end of the day, you—the individual taxpayer—are solely responsible for the accuracy of your own tax return. If Claude or ChatGPT misinterprets an IRS form and gets it wrong, and that mistake causes you to owe a lot of money or triggers an audit, you are the one holding the bag. The IRS won’t accept “but the AI told me” as an excuse. Penalties, interest, and potential legal consequences all fall on your shoulders, not on the AI company that provided faulty guidance.

The Larger Context: Why Americans Are Turning to AI Despite the Risks

Understanding why Americans are increasingly turning to these imperfect AI tools requires looking at the broader context of tax filing in the United States. Julie Siegel points out that people are turning to large language models in large part because of the absence of a free, government-provided filing tool that works well. The IRS had created a Direct File tool during the Biden administration that saved taxpayers an average of $160 each by allowing them to file directly with the government for free. However, this tool was eliminated, leaving taxpayers to navigate a landscape of commercial tax preparation services that often charge substantial fees, particularly for anyone with a slightly complicated tax situation. In this vacuum, free AI chatbots naturally look attractive—they’re available 24/7, they don’t charge fees, and they can answer questions immediately without requiring an appointment or a wait on hold. The appeal is understandable, especially for people on tight budgets who are looking at spending $100, $200, or more on tax preparation software or professional services. However, what seems like a money-saving shortcut could end up costing far more in penalties, interest, lost deductions, or overpaid taxes. The situation highlights a fundamental problem in American tax policy: our tax code has become so extraordinarily complex that ordinary citizens can’t reasonably be expected to navigate it without assistance, yet affordable, reliable assistance isn’t readily available to everyone. Until this fundamental issue is addressed—either through tax simplification or through accessible, government-provided filing assistance—Americans will continue to seek solutions wherever they can find them, even when those solutions come with significant risks.
