AI Is Raising New Red Flags for Professionals in Tax Season 2026

The other day, a partner at a mid-sized CPA firm told me, “Clients are asking if ChatGPT can just do their return this year.” He laughed, then paused. “They’re asking seriously.” That tension right there sums up tax season 2026. AI can draft contracts, summarize case law, and crank out marketing copy in seconds. Yet when it comes to signing a Form 1040 under penalties of perjury, most taxpayers still want a human in the room. And the data backs that up.

Is AI losing its nerve this tax season?

According to Invoice Home’s 2026 U.S. Tax Filing Report, only 37% of taxpayers said they would consider trusting AI over hiring a tax professional. Last year, that number was 43%. That is a meaningful drop in a single filing season. Comfort with AI slipped across every generation. Gen X fell from 43% to 40%. Millennials dropped from 54% to 50%. Gen Z slid from 49% to 46%. Even Baby Boomers and the Silent Generation pulled back slightly. At the same time, confidence in self-filing barely moved. Just 42% of respondents said they feel confident filing correctly, up from 41% last year. That means well over half the country still feels shaky about getting it right. So here we are.

Taxpayers do not fully trust themselves. They are cool with fully automated AI filing. But they are not exactly lining up to ignore technology either. Almost a quarter say they are seeking AI support for financial management, and 24% report using ChatGPT for financial advice. In other words, people want tech in the mix, but not holding the pen alone.

Why are deepfakes and IRS impersonators suddenly part of tax planning?

Layer on another reality: AI is not just helping professionals. It is also helping criminals. FBI data show government impersonation scams generated over 17,000 complaints in 2024, with losses exceeding $400 million. Total reported internet crime losses topped $16.6 billion. That is not small potatoes. Voice cloning, deepfake video calls, and hyper-personalized phishing emails have moved from sci-fi to everyday risk. A widely reported 2024 case involved fraudsters using AI-generated video and voice to impersonate senior executives during a video call, leading to approximately $25 million in fraudulent wire transfers. If a sophisticated engineering firm can get burned through a fake executive call, what do you think a stressed taxpayer feels when they receive a polished “IRS notice” by email or text?

Tax season creates the perfect storm: money on the line, refund expectations, and a tight timeline. AI has removed the sloppy grammar and awkward formatting that used to give scams away. As one cybersecurity executive put it, the tools are widely available now. You do not need elite technical skills. For practitioners, this changes client conversations. It is no longer enough to warn about suspicious links. Firms now need clear callback procedures for wire transfers, secondary verification for client data changes, and internal policies on AI usage. Trust but verify has become verify twice.

If taxpayers fear AI, why are they still using it?

Here is the twist. Even as fewer taxpayers say they would trust AI over a professional, they are still experimenting with AI tools. 24% of survey respondents said they are seeking support from AI in managing finances. Another 24% rely on ChatGPT for financial advice. Meanwhile, 29% are investing in digital tools, and 22% are hiring a financial planner for the first time. This is not an anti-tech movement. It is a recalibration. Professionals are seeing the same thing inside firms. AI tools are helping draft client emails, summarize IRS notices, extract data from PDFs, and streamline onboarding. Generative AI adoption is accelerating in bookkeeping and tax prep workflows. Many firms expect to use AI in financial reporting within the next three years.

Yet no serious firm is turning over final review to a bot. Audit evidence still requires professional skepticism. Tax positions still require judgment. Circular 230 still applies to a human name on the signature line. Tom Hood of the AICPA framed it well: Do you want your taxes done by AI, by a CPA, or by a CPA using AI? The answer for most clients is obvious. They want the trusted adviser who uses the best tools available. That is the sweet spot.

Are refunds masking deeper financial stress?

There is another layer here that should catch every practitioner’s attention. Early IRS data show the average refund is up roughly $200 compared to last year, aided by recent tax law changes and stable withholding tables. On the surface, that sounds like good news. Dig into the survey, and the picture shifts. 21% of Gen Z respondents said they rely on their tax refund to cover cost-of-living expenses the month they file. If the refund does not arrive as expected, 18% of Gen Z say they will struggle to afford rent or mortgage. 16% say groceries become an issue. 15% would need to set up a payment plan with the IRS. That is not a rounding error. That is real cash flow stress.

We are seeing this in practice. Clients treat refunds like forced savings. They plan vacations, pay off credit cards, or cover deferred bills. When a refund is smaller than expected, the phone lights up. When a client owes, the anxiety spikes fast. Combine that stress with AI-powered scams and a lack of confidence in filing accuracy, and you get a combustible mix. People want speed and convenience, but they also want reassurance that someone competent is watching their back. As Benjamin Graham famously noted, in the short run, the market is a voting machine, but in the long run, it is a weighing machine. Tax season feels similar. In the moment, convenience and novelty attract attention. Over time, accuracy and accountability carry the weight.

So where does this leave the profession?

AI is not going away. Deepfakes are not going away. Client expectations are not going back to 2015. But this season’s data suggest something important: taxpayers are drawing a line. They will use AI as a calculator, an assistant, maybe even a draft writer. They are not ready to let it sign their return alone. For firms, that creates both responsibility and opportunity.

• Responsibility means setting guardrails. Clear internal AI policies. Documented review procedures. Client education about impersonation scams and IRS contact methods. Proactive communication that the IRS does not initiate payment demands by text or gift card.
• Opportunity means leaning into hybrid service. Use AI to reduce admin time. Automate low-value tasks. Free up senior staff for planning conversations, entity structuring, and risk management. That is where real advisory value lives.

Ask yourself a few practical questions. Have you updated engagement letters to address AI usage? Do your staff know how to verify a suspicious client request that “sounds” like the partner? Are you educating clients about deepfake fraud as part of tax season outreach? This is not about hype. It is about discipline. The takeaway feels straightforward. AI will keep getting sharper. Scammers will keep exploiting it. Clients will keep feeling the squeeze from cost-of-living pressures. Through all of it, the steady hand of a licensed professional still matters. Tax returns may be numbers on a page. Trust is not.
