Is Tax Litigation Becoming More About Information Than Interpretation?

For years, tax litigation was often centred around one question: “What does the law mean?” 

Today, that question is increasingly being followed by another: “What does the data show?” 

With tax authorities having access to richer datasets, digital trails, third-party reporting, and advanced analytics, disputes are no longer driven only by different interpretations of the law. They are just as likely to begin with inconsistencies in information, documentation, or reporting. 

This doesn’t make legal interpretation any less important. But it does mean that businesses need to think beyond compliance. Strong documentation, consistent reporting across different filings, and reliable data governance are becoming just as critical as understanding the law itself. 

As professionals, our role is evolving too. We’re no longer only interpreting legislation we’re helping clients ensure that the information supporting their position is complete, consistent, and capable of standing up to scrutiny. 

In many cases, the strongest defence isn’t just a well-argued legal position. It’s well-managed information.
