As of early March, more than 36.5 million refunds totaling about $136.6 billion had been issued. The average refund is about $3,676 — roughly 10.6% higher than at the same point last year.So, the idea that a chatbot could help identify additional refund money may sound understandably appealing.But while AI may help explain tax rules or highlight areas worth reviewing, the process for changing a filed tax return is more structured than a viral post might suggest. Here's what you need to know.Artificial intelligence tools like ChatGPT, Perplexity, and Claude AI, to name just a few, have improved rapidly in recent years. In many cases, AI can help taxpayers better understand tax concepts or identify questions worth revisiting.For example, AI might help:In that sense, AI can serve as a useful research tool during tax season.However, identifying a possible issue on a return is very different from actually correcting a filed tax return.If a taxpayer discovers a legitimate mistake after filing, the IRS requires a formal process to correct the return.Common reasons taxpayers file an amended return include:In most cases, that means submitting Form 1040-X, the official amended return used to update previously filed tax information.Taxpayers generally have three years from the date the original return was filed — or two years from the date the tax was paid, whichever is later — to amend a return and claim an additional refund. After that window closes, the IRS typically will not issue the extra refund even if an error is later discovered.The amended return must clearly explain what changed and why. Taxpayers must also include documentation supporting the adjustment.In other words, a chatbot might help flag a potential issue with your return, but the IRS still requires proper documentation. If a legitimate error is found, taxpayers must file a formal amended return before the IRS can issue any additional refund.Amended returns are relatively uncommon. In most years, the IRS typically processes around 160 million individual tax returns, but it reportedly receives only a few million amended filings.Many discrepancies are identified by the tax agency's automated matching systems. Those compare income reported on tax returns with information submitted by employers and financial institutions on reporting forms like W-2s and 1099s.While AI can be useful for explaining tax rules or identifying areas worth reviewing, there are important limitations and potential consequences to consider.A few important limitations include:Privacy: Uploading sensitive financial information into an AI chatbot may expose personal data depending on how the platform stores or processes user inputs.Incomplete financial information: Most AI systems don't have access to a taxpayer’s full financial documentation, including W-2s, 1099s, receipts, and prior tax records. Without that full context, a chatbot may misinterpret eligibility rules or overlook important details.Timeliness of tax updates: AI tools may not have access to the most recent tax law changes, IRS guidance, or regulatory updates. Tax rules can change, as they did in the 2025 Trump/GOP tax bill. In some instances, chatbots may rely on outdated or incomplete information when responding to questions about recently enacted tax provisions.Potential inaccuracies and hallucinations: AI tools can sometimes misinterpret tax law or generate incorrect explanations, particularly when dealing with complex eligibility rules or uncommon deductions.If a taxpayer files an amended return requesting a refund they aren't entitled to, the IRS can deny the refund and may require repayment of any additional amount issued, with interest. Some taxpayers could also face accuracy-related penalties.Artificial intelligence isn't new to the federal tax system. The IRS already uses advanced analytics and machine learning to review large volumes of tax data and identify returns that may warrant closer review.For example, the tax agency uses automated systems to flag potential discrepancies, compare reported income against third-party records like W-2s or 1099s, and help prioritize enforcement resources.If you identify a legitimate mistake after filing, correcting it is relatively straightforward. To amend a return:1. Complete Form 1040-X2. Identify the changes being made3. Attach any supporting documentation4. Submit the amended return electronically or by mailThe IRS notes that amended returns can take up to 20 weeks to process.You can track the status of an amended return using the IRS “Where’s My Amended Return?” tool.AI might help taxpayers better understand tax rules or identify areas worth reviewing on a return. Even so, those tools are not a substitute for the IRS process required to change a filed return. If a legitimate error is discovered, you still need to document the change and file an amended return.Also, most tax software already checks for many common credits and deductions during the filing process. So that so-called "AI reviews" might not uncover additional refunds in many straightforward situations.If you're unsure whether you've claimed all of the tax benefits to which you are entitled, it's good to consult a qualified tax professional who can help ensure any corrections to your return are handled properly.Profit and prosper with the best of Kiplinger's advice on investing, taxes, retirement, personal finance and much more.
