Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.

The floor is 10 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“TaxJar (now part of Stripe Tax) stands out as one of the most affordable and highly rated sales tax compliance software options” Grok 4.1 Fast · Sales tax automation · budget prompt · first choice
“TaxJar is the strongest default choice because it is repeatedly positioned as a fit for small businesses/SMBs” Perplexity Sonar · Sales tax automation · budget prompt · first choice
“For many small ecommerce sellers, TaxJar or Stripe Tax provide a good balance of simplicity and automation.” GLM 4.7 FlashX · Sales tax automation · comparative prompt · first choice
“Known for automating the full sales tax lifecycle... especially suitable for small ecommerce sellers” Mistral Small · Sales tax automation · budget prompt · first choice

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.

“Avalara and TaxJar are described as better aligned to sales/use tax than income tax provision-to-return traceability, so they can be a poor fit for provision teams.” Perplexity Sonar · Corporate tax provision · negative prompt · hard negative
“it lacks depth in global invoicing and may not handle local compliance nuances well, making it a risky choice for international operations” Mistral Small · Global e-invoicing compl · negative prompt · hard negative
“Multiple sources indicate significant degradation since the acquisition... current user feedback suggests TaxJar may frustrate you.” Kimi K2 · Sales tax automation · negative prompt · hard negative
“TaxJar users have reported that the company openly admits their reporting is broken with no plans to fix it” Claude Haiku 4.5 · Sales tax automation · negative prompt · hard negative

What carried it into the answer

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

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 174 of the 185 answers that named TaxJar and are not a share of its labels.

How it is countedHide how it is counted

Every page taxjar.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person. Read September 29, 2026.

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 TaxJar'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 TaxJar, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for TaxJar by email, built from the raw record of the edition. It shows:

  • where TaxJar is named, by buyer and by framing, and which cells hold its first choices;
  • the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
  • its vocabulary against the segment leader's, and the pages the models cited;
  • who was chosen in the answers that did not name TaxJar, and every reason the record gives;
  • a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
  • one page of published figures cleared to show a buyer.
The subscriber app

A verification link goes to your work email; an address at taxjar.com is approved on the spot, any other is reviewed by hand. Your email is never published. Claiming gives no say over labels, shares, verdicts or which quotes appear.
