Deer Park, NY-based Sales Tax Defense, a firm specializing exclusively in sales and use tax matters, has joined Armanino, the top 20 accounting firm said on Tuesday.
Financial terms of the deal weren’t disclosed.
Armanino said this addition expands its capabilities in this highly specialized area, allowing the firm to better support clients facing multistate compliance, audit defense, and dispute resolution challenges.
“This is a powerful combination that significantly strengthens our tax consulting capabilities,” Matt Armanino, CEO of Armanino Advisory LCC, said in a statement. “Sales Tax Defense brings a team that lives and breathes sales and use tax, and equally important, understands the need to deliver superior outcomes for clients through exceptional service, and we couldn’t be more excited to have them on our team moving forward.”
Founded in 2008, Sales Tax Defense is a boutique tax consulting firm that provides sales, use, and transaction tax advice to businesses and other professionals.
According to the firm’s website, its core sales tax services include:
- Sales tax audit defense
- Multistate sales tax research
- Offer in compromise and voluntary disclosure
- Sales and use tax filings
- Payment plans and penalty abatements
- Nexus studies
Armanino said this focused expertise, coupled with increasingly complex tax law, complements its broader tax practice and strengthens the accounting and business consulting firm’s position as a comprehensive resource for clients with sophisticated needs.
“Joining Armanino allows us to bring our specialized experience to a broader range of clients, including larger enterprises that are increasingly facing complex multistate challenges,” said Mark Stone, CPA, MST, managing partner of Sales Tax Defense. “Together, we can offer deeper resources and additional capabilities while ensuring our clients and the CPAs that we work with continue to benefit from the hands-on approach Sales Tax Defense is known for.”
Armanino said in October 2024 it had received a minority investment from Further Global Capital Management, a New York-based employee-owned private equity firm that makes investments in businesses within the financial services industry. Armanino said at the time that the investment supports its strategic growth into additional markets, improves the firm’s technology infrastructure, and provides additional resources.
