TaxOrch is an innovative tax platform powered by AI that aims to enhance transparency and accountability in tax compliance and client management, offering a White-label licensing option for accounting firms, banks, and fintech companies. Distinct from conventional generative AI applications, TaxOrch does not attempt to estimate or fabricate financial figures. Instead, it integrates synthetic and generative AI with a stringent, rules-based tax calculator, ensuring that every number is substantiated by official tax regulations, complete with references to its source and applicable tax year. In instances where a rule lacks verification, TaxOrch proactively notifies the user, avoiding the provision of unreliable estimations. The platform streamlines intelligent document workflows by efficiently processing W-2s, 1099s, K-1s, P60s, T4s, receipts, and invoices, while also identifying missing documents and minimizing the need for manual document retrieval. Each engagement is meticulously managed through a comprehensive 14-step workflow that includes a maker-checker review process, sign-off from reviewers, and an audit trail designed to be tamper-evident. With an emphasis on enterprise-level data security, TaxOrch incorporates isolated workspaces, single sign-on (SSO), SCIM, and ensures compliance with data residency requirements. Furthermore, White-label partners have the flexibility to integrate their own certified tax rule sets under their branding, enhancing customization and brand identity for end-users. Through these features, TaxOrch not only boosts efficiency but also reinforces trust in the tax compliance process.
