BlackRock leads $500m Avalara equity deal

Avalara, a global leader in agentic tax and compliance automation, has announced a $500m equity investment led by BlackRock’s Private Financing Solutions.

Vista Equity Partners, which is Avalara’s majority shareholder, will retain its controlling stake. All proceeds from the investment will be used to purchase shares from existing shareholders.

Founded over two decades ago, Avalara has been instrumental in transforming tax compliance through technology. The company’s solutions serve more than 43,000 businesses and government entities in over 75 countries, offering a vast library of tax content and integrations to simplify complex compliance processes.

Avalara’s new Agentic Tax and Compliance™ platform leverages advanced AI technology to automate tax filings, registrations, and compliance tasks while maintaining human oversight.

Each AI agent within the system includes built-in checkpoints that allow for human review and approval, ensuring transparency and full audit-ready visibility for enterprises.

The platform’s architecture is powered by MCP servers, enterprise LLMs, and domain-specific SLMs, supported by a multi-cloud infrastructure engineered for scalability, resilience, and performance.

Avalara CEO and co-founder Scott McFarlane said, “Avalara’s mission is to be part of every transaction in the world.

“With support from partners like Vista, we’ve evolved from a single-product innovator to a trusted, comprehensive provider of tax and compliance solutions embedded in our customers’ financial systems through a powerful partner ecosystem. We’re proud to welcome BlackRock as an investor as we work to advance our position as a trusted provider of innovative tax and compliance software.”
