In an era marked by rapid technological advancement and increasing global cooperation, tax authorities are transforming how they monitor and engage with high-net-worth (HNW) individuals.

In this interview, Aidan Golden sits down with Stephen Atkinson, Global Head of Sales and Marketing in Utmost, to examine the implications of these changes—from predictive analytics and adaptive AI frameworks to the growing scrutiny of digital assets such as cryptocurrency. Together, they unpack what this means for clients and advisers, offering us timely insights into how transparency, accuracy and ethical planning are becoming central pillars of sustainable financial strategy.

 

Q: What has changed in how tax authorities are approaching high-net-worth individuals?

A: The landscape has shifted significantly. While tax authorities have always monitored wealthy individuals, they are now doing so with far greater precision. The integration of artificial intelligence, automation and international data sharing has enabled authorities to move beyond reactive audits to predictive oversight. Even minor inconsistencies can now trigger deeper investigations.

Authorities are leveraging data analytics to identify patterns, automation to handle vast volumes of information and cross-border cooperation to track assets globally. Traditional audits still exist, but they are now more targeted and intelligent.

Q: What types of technology are being used in this new approach?

A: A wide array of technology is in play with new developments occurring at a fast pace. Optical Character Recognition (OCR) is used to digitise handwritten tax returns, while AI-powered pattern recognition algorithms flag anomalies in financial statements. Predictive analytics can help forecast non-compliance based on historical behaviour. More advanced tools use neural networks and data mining to uncover are uncovering offshore fraud and complex ownership structures. Additionally, a newer framework known as Adaptive AI Tax Oversight is being implemented to enhance both accuracy and efficiency in fraud detection.

Basically, all areas of tax compliance are affected with the primary aim of identifying undeclared income or assets.

Q: Are there practical examples of these technologies being used by tax authorities?

A: Yes, I am hearing lots of examples where jurisdictions are already applying these tools. France uses aerial imagery and machine learning to detect undeclared swimming pools and property extensions. Spain employs AI chatbots to assist taxpayers and flag risky filings. Austria analysed 34 million cases last year and flagged over 375,000 for review using real-time risk scoring. Italy’s VeRa algorithm compares tax returns with bank data and flagged over a million high-risk cases in 2022. The Netherlands is scraping online data to uncover hidden ownership structures and undeclared income. Japan and Hong Kong have also enhanced digital reporting and automated compliance checks, particularly around cross-border wealth and digital assets.

Q: What about cryptocurrency? Is that receiving increased attention?

A: Absolutely. Cryptocurrency was once considered a blind spot, but that is no longer the case. Tax authorities are now using blockchain analytics to trace wallet activity and link it to real-world identities. The OECD has introduced the Crypto-Asset Reporting Framework and the EU’s DAC8 directive mandates crypto platforms to report user data. Agencies such as the IRS and HMRC are actively targeting crypto-related tax evasion. For high-net-worth individuals, crypto is now a visible and monitored component of their financial footprint. If you are interested in this area I recommend reading Marie Hainge’s article on crypto legislation in this issue of Navigator.

Q: What does this shift mean for wealthy clients?

A: It means that visibility is now the default. Clients must assume that their financial activities are being tracked across jurisdictions. Errors, whether intentional or accidental, are easier to detect. Systems can cross-reference filings, bank data and public records almost instantly. Enforcement is faster too; what once took months can now begin within days of a filing. Advisers have a heightened responsibility to understand not only local tax regulations but also how client data is interpreted globally.

Q: What is the key takeaway for advisers in this new environment?

A: We are entering a new era of accountability. Advisers must adopt a compliance-first mindset. This involves regularly reviewing client wealth structures, ensuring accuracy across jurisdictions and staying informed about regulatory developments. Insurance-based wealth solutions, such as those offered by Utmost, provide transparency, regulatory alignment and long-term planning flexibility. Ultimately, sustainable wealth management now hinges on ethical planning and accurate reporting with successful advisers likely to be those who take a proactive approach.

Q: In closing, what’s your one prediction about this new normal?

A: Taxpayers will move away from complex corporate multi-layered opaque structures to simple tax efficient solutions such as insurance-based wealth solutions.
