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.
Four commitments behind every screen.
Compliance-first
Every workflow assumes IRS Pub 1345, due diligence, retention, and audit trails — not bolted on after.
AI-forward
AI augments preparers, classifies documents, scores risk, and assists offices — without replacing professional judgment.
Operationally governed
Tenant isolation, role-based access, lifecycle management, and provisioning built into the bone.
Built for offices
Designed by operating a real tax practice. Every screen reflects how offices actually work, not how outsiders imagine they work.
"Tax offices deserve infrastructure that respects compliance, empowers preparers, and treats AI as an operator — not a gimmick. That's what we built."
