Built by a tax professional.For tax professionals.
ROSSNEXUS and R&A Pro-Tax exist because the tools that real offices need didn't exist as one ecosystem. After years of operating a tax practice and searching for systems that respected compliance, served preparers, and scaled like enterprise software — the only path forward was to build it.
More than 25 years of professional experience sits behind the service standards enrolled offices receive from Mason H. Ross Jr., Founder, President & CEO.
Four commitments behind every screen.
Compliance-first
Office readiness and required credentials come before software access. R&A does not guarantee IRS or bank approval.
AI-forward
Ask Zyiion™ provides AI-assisted public service guidance. Human representatives confirm eligibility and approval; AI does not replace professional judgment.
Operationally governed
Individual authorized accounts and clear office boundaries protect account-specific information.
Built for offices
Service standards informed by tax-office experience, with guided onboarding and support for independent offices.
"Tax offices deserve infrastructure that respects compliance, empowers preparers, and treats AI as an operator — not a gimmick. That's what we built."
