Research Scope and Qualification

Questions This Section Answers

• How many prompt observations qualified for the public benchmark this month?
• What is the difference between the raw collection universe and the qualified observations used as the public denominator?

The public benchmark is narrower than the raw collection universe by design. Brand-level percentages use the qualified observations as the public denominator, not the raw collection.

For full qualification rules, see AI Visibility Market Discovery Methodology.

Current Brand Standings

Questions This Section Answers

• Where do the tax preparation brands rank by valid recommendation coverage?
• How does presence rate differ from valid recommendation coverage in the standings?

This table is the primary current-month benchmark view, sorted by valid recommendation coverage.

How to Read the Standings

• Presence rate: share of qualified observations where the brand is mentioned at all.
• Valid recommendation coverage: share of qualified observations where the brand appears in a recommendation shortlist.
• Top-three rate: share of qualified observations where the brand appears in the first three recommendation slots.
• Rank-one rate: share of qualified observations where the brand is the first recommendation.
• Net sentiment: positive mentions minus negative mentions as a share of all mentions, ranging from -1 to 1.

Recommendation Coverage Movement

Questions This Section Answers

• Which tax software brand gained the most recommendation coverage since the July 2026 baseline?
• What drove Jackson Hewitt's coverage decline across the measurement series?

Largest Increase: TaxSlayer

TaxSlayer recorded the largest coverage increase, rising to 63.0% in October 2026 from 57.2% in July 2026, a move beyond normal month-to-month variation. The brand's top-three rate also rose to 14.8% in October 2026 from 9.2% in July 2026, and its rank-one rate rose to 1.5% from 0.4% in July 2026. TaxSlayer dipped slightly in August 2026 before rising through September 2026 and holding steady into October 2026.

Largest Decline: Jackson Hewitt

Jackson Hewitt recorded the largest coverage decline, with valid recommendation coverage falling to 10.2% in October 2026 from 18.5% in July 2026, beyond normal month-to-month variation. The decline was not uniform: coverage fell from 18.5% in July 2026 to 8.2% in September 2026 before recovering to 10.2% in October 2026. Its presence rate also fell to 13.6% in October 2026 from 23.9% in July 2026. The brand appeared in 68 qualified observations in October 2026, down from 124 in July 2026.

Category Leader: FreeTaxUSA

FreeTaxUSA remained the category leader with valid recommendation coverage of 84.1% in October 2026, down from 84.3% in July 2026, a move within normal month-to-month variation. Its rank-one rate moved down to 20.4% in October 2026 from 29.7% in July 2026. Its top-three rate rose to 70.3% in October 2026 from 60.9% in July 2026.

The remaining brands held steady within normal variation across the series. Cash App Taxes, eFile.com, H&R Block, Liberty Tax, TaxAct, and TurboTax all remained within normal month-to-month variation from baseline to current.

Recommendation Placement Snapshot

Questions This Section Answers

• How can brands with similar recommendation coverage have different first-position rates?
• Which brand claims the first recommendation position most often among the leading cluster?

Coverage alone does not show how prominently a brand is recommended. The leading cluster shows how placement rates can differ meaningfully even when coverage is similar.

FreeTaxUSA holds slightly higher coverage than TurboTax in October 2026, but TurboTax claims the first position at 50.2% versus 20.4% for FreeTaxUSA, and TurboTax's top-three rate of 72.4% exceeds FreeTaxUSA's 70.3%. Close coverage can still hide different first-position rates.

Buyer-Intent Distribution

Questions This Section Answers

• What buyer-intent class did qualified observations fall into this month?
• Which buyer-intent classes are not yet represented in the public series?

All qualified observations in both months fell into the Brand Recommendation class of discovery, where consumers are seeking which brand to use.

The current public series measures the Brand Recommendation class of discovery and does not yet contain qualified observations in the Pricing & Value or Multi-Brand Comparison classes.

Historical Measurement Record

Questions This Section Answers

• Who has held the coverage lead across all recorded measurements?
• Has the largest coverage movement changed month over month in this evergreen benchmark?

This is an evergreen benchmark URL. New measurements are added to the same report.

Evidence and Source Layer

Questions This Section Answers

• What source information is retained for each prompt-level observation?
• Does citing a source prove it caused a brand recommendation?

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

The overlap rate between the current leader and previous leader remains high, with all ten tracked brands appearing in both July 2026 and October 2026.

Scope Boundaries

This public benchmark does not measure:

• Market share or sales attribution
• Every possible AI response to a given query
• Organic search ranking positions
• Social media mention volume
• Private or sponsored channels
• Causality from a metric movement alone

Top 10 Cited Domains

Questions This Section Answers

• Which domains are cited most often across AI surfaces in tax preparation software?
• How concentrated are citations among the top ten domains, and which brand domains appear in the list?

The benchmark observed 6,528 total citations across 678 unique domains in October 2026.

Citations are moderately concentrated: the top ten domains account for roughly 44% of all citations, with the remaining citations distributed across the long tail of 668 additional domains. Two tracked brand domains appear in the top ten: freetaxusa.com at rank five and hrblock.com at rank eight. Government and news sources lead the list, with irs.gov and cnbc.com occupying the top two positions, followed by consumer technology and product review sites including cnet.com and pcmag.com. Community and video platforms including reddit.com and youtube.com also feature prominently, suggesting that AI surfaces draw on both official guidance and third-party evaluations when shaping recommendations in this vertical.
