Module 3:
Tax Control Framework + Tax Tech Stack

The modern tax function cannot rely on spreadsheets and ad-hoc checks anymore. A Tax Control Framework (TCF) is the backbone of governance. Effective governance starts with an operating model design, ensuring that risks are identified, processes are followed, and reporting is consistent across all entities. PwC consultants emphasise that organisations often underestimate that control isn’t a one-off project. A strong TCF allows companies to move from reactive compliance to proactive governance.

A robust TCF typically includes:

• Policies and procedures for each jurisdiction
• Risk identification and mitigation measures
• Process monitoring and controls
• KPI measurement and reporting

VJ reflects on Shell’s experience: “Our Tax Control Framework gave leadership confidence that every process was under control, even across 100 countries.” With the right framework, tax work becomes visible, measurable, and repeatable — even in complex multinational operations.

The next step is understanding where risks can occur and how processes flow. Process mapping visualises each task, handoff, and approval. Risk registers capture compliance gaps, inefficiencies, or areas prone to error — and critically, the data connected to each risk should be readily available, enabling teams to act swiftly when issues arise. A clear audit trail ensures that when risks do occur, they can be mapped back to their source, providing full transparency and accountability across the process.

PwC highlights that integration with enterprise risk management is key by stating that a TCF should not exist in isolation. It needs to be linked to broader organisational risk and ESG objectives.

VJ’s experience at Shell shows us to start small and focus first on the most material or high-risk entities and processes. Testing, refining, and learning from early pilots ensures the framework is resilient before full-scale rollout.

Control without measurement is blind. Modern TCFs rely on KPIs to track performance and improvement. Key indicators may include:

• Accuracy of filings
• Timeliness of submissions
• Risk mitigation effectiveness
• Cost efficiency
• Automation adoption rates

As Djanno once put it: “If you don’t measure what matters, you can’t improve what matters.” KPIs provide the feedback loop necessary to continuously refine processes and reduce risk exposure over time.

Technology is no longer optional — it is what allows a TCF to scale globally. A tax tech stack may include:

• One true source of data
• Workflow tools to reduce manual work
• Data analytics and dashboarding for risk detection and benchmarking
• AI-driven tools for anomaly detection and scenario planning

VJ recalls Shell’s approach: “We combined automation with process ownership. The tech was there to support, not replace, the people — and that made the difference.”

Choosing the right tools is critical. It’s not about having the latest software, but about how technology fits your governance model, integrates with existing systems, and drives adoption according to the consultants of PwC.

A successful TCF isn’t just about rules or software — it’s about how people, processes, and technology interact. Clear roles (as covered in Module 2) ensure accountability, while technology streamlines execution, and the TCF defines the rules.

Even the best technology or framework will fail without leadership sponsorship and engaged teams. Identifying “cheerleaders” in your team — employees who can champion change — helps navigate resistance and accelerate adoption.

Implementing a TCF with a tech stack requires careful planning:

1. Start small:
   Pilot key processes and high-risk entities.

2. Test and refine:
   Document what works and what doesn’t.

3. Roll out globally:
   Gradually introduce the framework to other regions, mixing easier and complex cases.

4. Monitor and improve:
   Use KPIs to track performance, identify bottlenecks, and continuously evolve.

VJ advises: “Start with the easy wins but always plan for the complex ones — your TCF should be built to last, not just to survive the first year.”
