The future of tax in Alternatives starts with data

  • November 18, 2025

In today's world, tax is no longer just about being compliant with statutory filings. In the alternative investment industry especially, large transactions, complex global structures, and rising regulatory scrutiny are forcing tax managers to fundamentally rethink how they work. Tax teams must shift from form-filling and reconciliations to strategic advice, complex structure management, and global reporting consistency. For alternative investment managers, this evolution isn’t only about compliance — it also affects regulatory risk, investor confidence, and the speed of closing deals. The foundation to turning these challenges into strategic advantage? Well-organised, high-quality data.

Why tax is now in the spotlight

Tax functions worldwide are under growing pressure. Global initiatives such as Pillar II and DAC8 increase complexity, yet most tax teams must manage these demands with constrained budgets, leaner teams, and shorter deadlines. At the same time, tax authorities are modernising: traditional audits based on manual document checks are giving way to data-driven supervision, including semi-automated submissions, e-audits, real-time reporting, and mandatory e-invoicing.

The OECD’s report Tax Administration Digitalisation and Digital Transformation Initiatives (2025) highlights that tax administrations are increasingly using AI across their operating model. Central to this is the collection and analysis of large volumes of data, which enables AI systems to identify patterns and assess risk more effectively. For example, Luxembourg’s VAT authorities have introduced the OECD-recommended Standard Audit File for Tax (SAF-T), locally known as the Fichier Audit Informatisé AED (FAIA), requiring structured, machine-readable data directly from accounting or ERP systems.

These developments reflect a broader trend: tax authorities are increasingly seeking access to live, transaction-level data, making outdated systems, manual workarounds, and siloed information flows unsustainable. Closing this digital gap is not just about compliance, it is a key step toward transforming the tax function into a proactive strategic partner.

From pressure to pain: a real-world example

The following example, based on common industry situations, features TechNova, a hypothetical private equity firm. During a year-end closing, the tax authorities requested detailed reconciliations for 10 fund entities within just 10 working days. The data needed was scattered across inconsistent spreadsheets and fragmented ERP systems. What followed were weeks of late nights, urgent calls with service providers, and repeated back-and-forth with deal teams simply to compile the numbers. By the time TechNova submitted, the tax authorities had already flagged inconsistencies. The case was eventually resolved, but only at the cost of strained regulator relationships, additional professional fees, and an exhausted tax team.

This example shows how crucial it is to have structured and reliable data. Without a proper database, even skilled tax teams will struggle to provide an appropriate response to regulatory requests in due time. 

The data is there, but often out of reach

Every transaction a business makes can carry tax implications. Yet many tax professionals still spend a large part of their time gathering, cleaning, and reshaping data to make it usable.

Recurring challenges include:

  • Dispersed data sources: ERP platforms, spreadsheets, and local databases rarely provide ready-to-use formats;
  • Manual intervention: Human effort increases error risk and slows processes;
  • Regulatory pressure: Authorities expect granular, real-time, transparent data; and
  • Limited visibility: Tax often lacks real-time access to operational data.

At TechNova, tax-related data was spread across multiple systems, so even simple reconciliations required constant back-and-forth. This slowed down processes and increased risk.

Why data strategy is key to tax transformation

PwC’s 2025 Asset Management Compliance Insights Survey found that firms are shifting from many small tools to integrated platforms. Yet many still struggle to achieve results because the underlying data is fragmented or poorly governed. This reflects the industry’s broader push toward digital transformation and highlights why structured data is critical.

It’s important to remember that technology alone cannot achieve this. Digital tools deliver value only when supported by clean, structured, and well-governed data.

We have seen several players in the alternative investment industry invest heavily in advanced platforms and technologies to be disappointed by the results. The reason? Poor data. Technology alone cannot solve tax challenges if the underlying data is fragmented, inconsistent, or poorly governed.

For example, firms deploying workflow tools, robotic process automation, or even AI without first addressing data quality often find themselves spending even more time reconciling mismatched inputs and correcting errors. Without a clear strategy for how data is captured, structured, and maintained across the organisation, new tools create complexity rather than clarity.

The lesson is clear: digital investments only deliver value when built on a solid data foundation.

For TechNova, listing all required data points across regions and output filings was the first step. They are now streamlining processes, leveraging technology and AI to increase automation, and focusing on higher-value tasks. The result? Reconciliations that once took weeks can now be completed in days.

Building a foundation with structured data

The future of tax compliance is moving toward seamless integration and real-time exchange of information. Increasingly, clients are looking to connect their data environments (cloud-based warehouses or internal systems) directly with their tax service providers. To achieve this, tax teams need to start today by structuring and standardising their data, systematically organising and classifying it from the start, defining clear categories, applying consistent naming conventions, and using standardised formats.

When tax data is clean, centralised, and connected, teams can reduce compliance risk through automated controls, enhance decision-making with real-time access to transaction-level details, free up time by automating routine data work, and respond quickly to regulatory changes. Structured, connected data also makes it easier to establish governance, define ownership, and implement automated checks for accuracy, consistency, and compliance, laying the foundation for a resilient, future-ready tax function.

Three priorities for tax managers?

To conclude, having explored why data is essential, today’s challenges, and what tax needs to achieve, we suggest three key areas that tax managers may consider prioritising to build a future-ready function:

  1. Get involved early in digital initiatives – Don’t wait for technology to be rolled out. Join projects from the start to influence how systems are designed, ensure data is structured correctly, and make reporting and compliance easier. Early involvement saves time, reduces errors, and ensures technology actually meets tax needs;
  2. Build diversified tax teams – Focus on developing a team with the right mix of skills. PwC’s 2025 Asset Management Compliance Insights Survey highlights that leading firms are complementing technical tax expertise with strong data management and digital skills. For tax teams, this means being able to structure and analyse the detailed data behind transactions to meet new requirements such as Pillar II and DAC8. Tax managers who build digitally fluent teams will not only reduce compliance risk but also position the tax function as a strategic business partner; and
  3. Partner with strategic advisors – Choose advisors who go beyond filing tax returns. Look for those who understand your business, your data flows, and can help design processes, ensure governance, and anticipate regulatory changes. The right advisors become true partners, not just service providers.

By acting on these priorities, tax managers not only strengthen compliance but also reduce regulatory risk and create the confidence to move faster on strategic transactions.
