September 2026 Edition. Every number here is derived from the raw labels under vendor table vv2026-09.2, every buyer segment counted.

Standing

4 labels, too few to rank

A product needs 10 labels in a category before a share or quadrant is stated. TaxSlayer was named 4 times in Corporate tax provision, where Thomson Reuters ONESOURCE Tax Provision led with 26%. The labels and the evidence are below, counted exactly.

Movement

This is the first edition on this tier, so no move can be computed for TaxSlayer yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Lowest viable software cost: TaxSlayer Pro (~$540/year)” GLM 4.7 FlashX · Corporate tax provision · budget prompt · first choice

“TaxAct or TaxSlayer are the clearest low-cost picks in the results, but those are better aligned to tax preparation” Perplexity Sonar · Corporate tax provision · budget prompt · alternative

“Best for: Price-sensitive filers” MiniMax M2.5 · Corporate tax provision · budget prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“found glitches missing deductions; some poor support access.” Grok 4.1 Fast · Corporate tax provision · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named TaxSlayer. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 10 of the 10 answers that named TaxSlayer and are not a share of its labels.

Is this your product?

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when TaxSlayer's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as TaxSlayer, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at taxslayer.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
