Tax compliance has traditionally relied heavily on people to manage documentation, withholding and reporting obligations. But as financial institutions face increasingly complex tax rules across multiple jurisdictions, the operational burden is growing, creating demand for technology that can handle more of the process without removing human oversight.
Artificial intelligence could provide part of that solution. TAINA Technology argues that AI is beginning to change the role of tax operations, moving the function away from labour-intensive administrative work and towards more automated workflows that can monitor information, identify potential issues and trigger action.
Tax operations teams currently spend substantial time reviewing tax forms, checking supporting documentation, validating Tax Identification Numbers and monitoring whether documents are approaching expiry. They can also be responsible for answering routine customer queries and managing large-scale resolicitation campaigns.
These activities are essential for meeting requirements including FATCA, IRS Chapter 3 and Chapter 4 rules and the OECD Common Reporting Standard. However, their repetitive nature makes them potential candidates for automation.
Specialised AI agents could be assigned different responsibilities across the tax documentation process. One agent could determine which forms a customer needs, while another checks information against supporting documents. Further systems could validate Tax Identification Numbers, monitor documentation or identify potential changes in customer circumstances.
The greater opportunity comes when these individual capabilities are connected. Rather than using technology to automate isolated tasks, financial institutions could create workflows in which information gathered at one stage automatically informs the next.
This could help move tax compliance towards continuous monitoring. Instead of discovering an issue during an annual review or in the run-up to a reporting deadline, institutions could identify potential problems as they emerge and intervene earlier.
Tax documentation resolicitation is one area where this approach could have a significant operational impact. Forms can expire, customers can change their tax residency and companies can restructure, potentially creating a need for updated documentation.
The traditional process can require teams to identify affected accounts, prepare communications, track responses and repeatedly follow up with customers. When carried out across large customer populations, this can create a significant administrative workload.
TAINA’s Resolicitation Agent, TAINA-Renew, is designed to automate parts of this process. It can analyse account data to identify expired or soon-to-expire forms before preparing personalised email and letter communications using approved templates.
Human oversight remains part of the workflow, with users able to review and authorise communications before they are sent. This allows AI to reduce preparation and administrative work while keeping professionals responsible for customer-facing decisions.
When integrated with TAINA’s tax documentation platform, the agent can take the process further. It can monitor relevant information through a direct feed, identify events that could trigger a documentation requirement and initiate outreach. Customers can then be directed to secure, authenticated journeys to complete the required forms.
The workflow can also track whether documentation has been received and update solicitation statuses, connecting identification, outreach, customer action and completion monitoring.
For the wider RegTech sector, this illustrates a broader move towards AI that can manage workflows rather than simply perform individual tasks. Technology could increasingly identify a compliance issue, determine the appropriate next step and escalate cases that require professional judgement.
Governance will remain critical as this develops. Tax documentation can influence withholding and reporting, so financial institutions need transparency around automated decisions, clear escalation rules and audit trails showing what actions were taken and why.
The emerging model is therefore likely to combine automation with human expertise. AI can manage repetitive activity at scale, while tax professionals retain responsibility for complex cases, regulatory interpretation and material compliance risks.
TAINA Technology’s analysis suggests this could ultimately reshape tax operations around continuous monitoring and proactive intervention, rather than periodic compliance exercises. For financial institutions, the result could be a more scalable approach to managing increasingly complex tax obligations without sacrificing oversight or accountability.
