TurboTax vs H&R Block: whose tax AI is actually better?
Two incumbents, two very different AI strategies — and a sharp split in what you get for free versus what triggers an upgrade.
TurboTax and H&R Block between them handle a large share of American tax returns, and both now put an AI assistant at the centre of the DIY experience. The products are close enough on filing mechanics that the AI, the human backstop, and the pricing model are where the decision actually gets made.
They have taken different routes. Intuit built Intuit Assist into TurboTax and is simultaneously expanding physical presence — nearly 600 tax offices and around 20 TurboTax storefronts for the 2026 season. H&R Block, which has had offices since 1955, built AI Tax Assist with Microsoft and trained it using its in-house Tax Institute of CPAs, tax attorneys, and enrolled agents.

The AI assistants, side by side
Intuit Assist answers tax questions in plain language within the context of your return, checks in real time for errors and missed deductions or credits, and reads uploaded documents to auto-fill forms. Intuit reported roughly $90 million in annualised efficiencies from its AI investments in the first half of 2025, which tells you how central this is to the company.
AI Tax Assist is free inside H&R Block's DIY online and desktop products, answers unlimited questions at around two seconds per response, and — the meaningful part — can hand off to a live tax professional at no extra charge. Usage has grown 152% since its 2023 launch to 6.45 million cumulative messages, including 1.91 million in the 2026 season alone.
The free-human-handoff is the real differentiator
The pattern in AI tax support is that the assistant handles the easy 80% and the hard cases still need a person. What differs is what that escalation costs. H&R Block includes the handoff from AI Tax Assist to a live professional at no extra charge, which is why CNET named its platform Best Overall Tax Service and Best Use of AI for 2026.
TurboTax's equivalent access is a paid tier. That is a defensible model — but it is the single most common source of complaint, where the objection is not that the AI failed, but what reaching a human then cost.
What the complaints are actually about
Both brands attract the same criticism, and it is not about the AI. The recurring complaint is commercial: fees that appear partway through a return, upgrade prompts triggered by a form you did not know was premium, and difficulty reaching a person once something goes wrong.
That matters more than it sounds, because the cost of switching rises the further into a return you are. Price the escalation path before you start — what a human costs, whether it is bundled, and at which point the product decides your situation is no longer simple — rather than discovering it at the end.
