Case Study - Automating Tax Form Collection at a Global Tier 1 Bank
Case Study: Global Tier 1 Bank Automates CRS Tax Form Collection at Enterprise Scale with TAINA
A global Tier 1 bank modernised its CRS tax form collection across multiple regions and business lines by digitising customer self-certifications with TAINA’s API-first solution.
Legacy paper and PDF-based processes slowed onboarding, increased operational risk, and created friction for customers. By embedding TAINA’s guided online journey into its existing onboarding and remediation flows, the bank achieved straight-through processing, significantly improved data quality, and unlocked enterprise-wide scalability, without changing its front-end experience.
Discover how this Tier 1 bank transformed tax documentation into a seamless, compliant, and fully digital customer journey.
