Tax Advisory Platform

Tax Advisory Platform

TaxPlannerPro needed to modernize its decade-old tax software and transform it into a scalable, cloud-based advisory platform for U.S. tax professionals. MindInventory re-architected the legacy system into a multi-tenant SaaS platform with a modular tax engine, AI-assisted document processing, strategy simulations, and dedicated Admin, Accountant, and Client portals. The solution enabled tax firms to move beyond compliance-focused filing toward proactive, data-driven tax advisory.

Challenge

  • Legacy infrastructure: The decade-old technology had become slow, brittle, and increasingly difficult to enhance or maintain.
  • Hard-coded tax rules: Tax logic was embedded directly into application code, making annual tax-law updates complex and risky.
  • Manual data entry: Client information was scattered across PDFs, spreadsheets, QuickBooks, and Drake, requiring repetitive manual re-entry.
  • Limited advisory capabilities: The existing system primarily supported tax filing and lacked tools for scenario modeling, strategy comparison, and advisory reporting.
  • Scalability requirements: The platform needed to support multiple accounting firms while securely isolating their data and workflows.
  • Limited client engagement: Tax professionals lacked a dedicated client-facing experience for sharing strategies and reports.italic text

Solution

  • Re-architected the legacy application into a cloud-based, multi-tenant SaaS platform.
  • Developed a modular and configurable tax engine to simplify tax-rule updates without requiring application-code changes.
  • Implemented AI-assisted document intake using Amazon Textract and Claude to extract and structure information from tax documents.
  • Added an advisor review workflow to ensure extracted data was validated before entering the tax calculation engine.
  • Built nine tax strategy simulation modules to help advisors model, compare, and evaluate different scenarios.
  • Developed separate Admin, Accountant, and Client portals with role-based access controls.
  • Introduced white-label capabilities, allowing tax firms to provide the platform through their own branded subdomains.
  • Integrated essential business systems including QuickBooks Online, Drake Software, Stripe, and SendGrid.
  • Built the platform on a modern technology stack using React, Node.js, PostgreSQL, and AWS for scalability and reliability.
  • Designed the architecture with independently evolving tax calculation, document processing, and reporting components to support future growth.
