When AI engines like ChatGPT, Claude, and Perplexity answer questions about tax advisory firms, EY comes up most often, appearing in 75% of relevant AI responses across the engines tracked. Deloitte and PwC follow closely, rounding out a Big Four dominated top three. If you ask an AI assistant to recommend a tax advisory firm, these three names will almost certainly appear in the answer.
The rankings reflect where AI engines pull their information from. The top cited sources include vault.com (a career and firm-ranking aggregator), forbes.com, reddit.com, youtube.com, and ryan.com. The presence of aggregator and community sites means AI engines are weighting third-party comparative rankings and user-generated discussion heavily, not just official firm websites. Firms that appear frequently and positively across those platforms earn more AI visibility.
For a buyer using this page, the practical takeaway is this: AI engines reward firms with broad third-party validation across review and ranking sites, not just brand size. When shortlisting firms, check whether a firm has strong coverage in your specific tax need (international tax, transfer pricing, R&D credits) on sites like Forbes or Reddit, because that topical specificity is exactly what pushes a firm higher in AI-generated recommendations.
At a glance
What we observed in this categoryauto-generated
EY dominates AI visibility in the tax advisory category with a 75.0% visibility score, a composite score of 52.5, and a gap of 62.5 percentage points over the next closest brands, Deloitte, PwC, and KPMG, which each sit at 12.5%. The category average visibility is just 5.6%, meaning EY is running at roughly 13 times the average. This concentration at the top is unusually steep even by professional services standards, and it means the vast majority of AI-generated answers in this category are dominated by a single firm.
A notable divergence exists between visibility and citation across the top brands. EY, Deloitte, PwC, and KPMG each hold a 0.0% citation rate despite their visibility scores. Ryan, ranked fifth with 0.0% visibility, is the only brand in the top five that earns any citation at all, at 12.5%. This pattern means the Big Four are named frequently in AI responses but are not being sourced as reference links, while Ryan is cited as a source without appearing in AI-generated narratives.
Google AI Mode is the sole engine recorded for every brand in this audit, suggesting the dataset is anchored entirely on that platform. The top cited external sources include vault.com, forbes.com, reddit.com, and nerdwallet.com, none of which are the firms themselves, with ryan.com being the only brand domain appearing in the cited sources list. This indicates AI responses in this category draw heavily on third-party ranking and review platforms rather than the firms' own content.

How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically. How AI search ranking works →
