The TaxJar installed base represents one of the most commercially valuable B2B target segments available. Companies that have already invested in TaxJar have demonstrated a willingness to purchase and deploy enterprise software — they have budget, a procurement process, and decision-makers who are accustomed to evaluating technology solutions. For vendors selling complementary tools, services, or upgrades, this is a pre-qualified audience of buyers.

Unlike generic email lists or broad industry databases, the TaxJar users list is built on verified technology install signals. ELP Data tracks which companies are actively running TaxJar through job postings, LinkedIn technology signals, integration partner data, and direct verification — meaning every company in the list is a confirmed TaxJar user, not an estimate. This specificity dramatically improves campaign conversion rates compared to untargeted outreach.

The decision-makers in this list — CFO, Controller, Finance Director, Bookkeeper — hold direct budget authority for technology purchases in the 86,518 companies using TaxJar. They are actively engaged with the Accounting Software ecosystem, making them highly receptive to relevant vendor outreach, especially for solutions that integrate with, extend, or modernise their existing TaxJar environment. Timing matters: companies that have recently deployed TaxJar are in an active expansion phase and are most likely to purchase additional solutions.

ELP Data refreshes the TaxJar users list quarterly, removing companies that have churned off the platform and adding newly identified users. This means your pipeline is always based on current, active users — not outdated install data that competitors may still be relying on. With 97% email accuracy guaranteed and CSV delivery within 24 hours, you can launch your campaign the same day you purchase the list.
