Rank inside each engine’s own top 10 · a dash means the brand is not in that engine’s top 10 · n/a — the engine gave too few answers here to publish a ranking.
The rest depend on which engine the buyer opens — so a rank from a single engine is not a market position.

Frequently asked questions
What does this Tax Preparation & Accounting Services AI Search report measure?
Which tax preparation & accounting services brands ChatGPT, Gemini and Google AI Mode name when buyers in the United States ask them for advice. We asked 400 buyer questions, each once to each engine, and counted how often every brand appears and which websites the engines cite. Measured Oct 2026.
What does “mention rate” mean?
The share of questions where an engine names the brand in its answer. A 10% mention rate means the brand came up in about one question in ten. Every rate carries a 95% range: the interval the true value most likely falls in.
How are the top Tax Preparation & Accounting Services brands ranked?
By mention rate, separately for each engine — pick the engine above the table. When two brands’ 95% ranges overlap, their order is not really different — tick “Only distinguishable places” to see the ranks the data can actually separate.
Why does a brand rank differently across AI engines?
Each engine retrieves from different sources and weighs them differently, so the brands it knows best differ too. Only 8 of 12 brands make the top 10 of every engine here; the rest depend on which engine the buyer opens.
What counts as a citation?
A link or source an engine shows alongside its answer. We record every cited domain, whether it appears inline or in the source list.
Why can AI mention a brand without citing its website?
Engines learn brand names from reviews, expert sites, retailers and forums, then cite those sources rather than the brand’s own pages. A brand can be named often while its own site is rarely among the sources.
What does “share of citations” mean?
Of all the citations one engine gave across our questions, the share that went to a given domain. The shares of one engine add up to 100%.
Will I get the same answers if I ask these questions myself?
Not word for word. AI answers vary between runs, accounts and locations, which is why we ask every question once to each engine and report a 95% range instead of a single answer.
