Disconnected technology is creating an increasingly difficult environment for financial institutions managing tax compliance. Processes such as document collection, data validation, customer monitoring and remediation have traditionally been handled by separate applications, leaving compliance teams to reconcile information across systems and rely on manual work to maintain a complete record.
TAINA Technology’s Lé-Anne Voges identifies this lack of integration as a central weakness in the traditional approach. Rather than continuing to add individual products to an already complex technology estate, institutions are showing greater interest in connected platforms that bring the different stages of tax documentation and compliance together.
The pressure is growing as reporting requirements become more demanding. CRS 2.0 and CARF are expanding the information institutions need to collect and report, increasing the number of data points, documentation requirements and jurisdictions they must manage. When systems operate in isolation, regulatory changes can trigger updates across several applications and suppliers, creating more opportunities for inconsistent information, delays and gaps in oversight.
Fragmentation also creates challenges for compliance governance. Institutions are responsible for maintaining the connections between collection, verification and record-keeping systems, often requiring internal IT teams to oversee integrations that can become difficult to maintain. When evidence is distributed across multiple applications, demonstrating how a compliance decision was reached can also become a time-consuming exercise during an audit or regulatory review.
As a result, the evaluation of RegTech platforms is moving beyond individual functionality. Institutions increasingly need to understand whether a provider can support connected workflows, maintain consistent data and accommodate new regulatory requirements without requiring a succession of additional integrations.
A more joined-up architecture can bring different forms of tax documentation into a common validation process. Information submitted through digital forms, populated through APIs using existing AML and KYC records, or extracted from bulk documents using OCR can be assessed against the same rules engine. This creates a consistent basis for determining whether information is complete and valid, regardless of how it entered the institution.
Integration capabilities are equally important. Tax Form, Taxpayer Identification Number (TIN) and withholding APIs can extend the rules engine into existing institutional systems, allowing firms to retain their established customer journeys while connecting compliance processes behind the scenes. Additional workflows, such as Accounts Payable tax compliance, can operate with their own permissions while sharing the same underlying logic.
The approach can also bring change-in-circumstance monitoring, remediation and audit trails into the same environment as collection and validation. This helps reduce manual transfers between applications and gives compliance teams a more continuous view of the documentation lifecycle.
When assessing providers, institutions should therefore look beyond a product’s ability to meet a single requirement. They should ask how it handles a customer’s journey from onboarding and initial validation through to changes in circumstances, remediation and the production of evidence for an audit. Demonstrations should make clear where information is stored, how it moves between components and whether any stages still depend on disconnected systems.
TAINA Technology is advocating a move away from collections of standalone tools towards connected compliance ecosystems, in which institutions can manage more of the tax documentation lifecycle through shared processes and infrastructure. With CRS 2.0 and CARF increasing the demands placed on reporting and oversight teams, the ability to maintain consistent controls across connected workflows is becoming a more significant consideration for RegTech buyers.
