The Future of VAT Consulting in the AI Era

Like many other professional services, VAT consulting and advisory are undergoing a period of structural change. For decades, much of the profession has relied on specialist knowledge, manual tax research, spreadsheets, compliance reviews, and repeated analysis of similar transactions across different jurisdictions. AI is changing how this work is done, while the wider digitalization of VAT is changing what businesses need from their advisers.

Both professionals and regulators are moving quickly to adopt AI. Thomson Reuters reported in 2025 that 79% of tax, audit and accounting firm professionals expected AI to have a high or transformational impact on their industry within five years. At the same time, tax administrations are also adopting AI: the OECD reported that 69% of tax administrations were already using AI in 2023, while another 24% were implementing it.

This points to an important fact: AI is more than a passing trend; it is a transformative tool for professionals. VAT consultants and advisors must be careful about how they implement and use AI in their day-to-day operations. Although it is a promising technology that might make VAT professionals' lives easier, it does come with risks.

From Billable Research to Technology-Enabled Advisory

Traditional VAT consulting often involves significant research. A consultant may need to determine the place of supply, VAT liability, registration obligation, applicable rate, invoicing requirements, or reporting treatment for a particular transaction. The process can require reviewing legislation, administrative guidance, case law, and other sources, and, in more complex cases, across multiple jurisdictions.

If used properly, AI can reduce time required for many of these steps significantly. Generative AI tools can search, summarize, and compare large volumes of information. Specialized tax technology can go further by integrating legislation, tax databases, and business data into a single workflow.

As a result, VAT professionals may increasingly spend less time finding the relevant rule and more time determining how that rule applies to a client's business model, systems, contracts, and transactions. Ultimately, this marks a transition from billable research towards technology-enabled advisory.

The VAT Consulting Tasks Most Likely to Be Automated

Not all tasks and activities are suitable for automation. The most suitable ones are repetitive, structured, and data-intensive tasks, such as VAT registration assessments, transaction classification, VAT rate identification, invoice reviews, compliance calendars, and preparation of standard documentation.

AI can analyze documents such as contracts, invoices, transaction records, and legislation, then interpret the data and flag potential VAT issues for human review. It can also compare information across systems and highlight discrepancies that would otherwise require substantial manual effort. The rise of e-invoicing and digital VAT reporting systems such as those planned under the EU ViDA VAT reform will only increase the need to cross-check and verify data, an area where AI will play an integral role. 

New Opportunities Created by AI

While VVAT professionals may feel pressured or threatened by A, automation also creates new opportunities. When routine analysis becomes faster, consultants can devote more resources to complex issues, implementation projects, and strategic advisory services.

One of the most promising opportunities is continuous VAT risk monitoring, which can largely be automated. AI systems could monitor and analyze key VAT data against applicable VAT rules and identify unusual treatment, missing information, or potential compliance risks. Once the system flags potential risk, consultants and advisors may then investigate further specific cases rather than manually reviewing every transaction.

Monitoring VAT changes is particularly critical for international companies that operate in multiple jurisdictions. With AI, VAT professionals could create a centralised view of key requirements across numerous jurisdictions, including registration, invoicing, VAT rates, and reporting obligations, and focus on jurisdiction-specific interpretation and implementation. 

The Changing Economics of VAT Consulting

AI not only changes how the work is done, but also how VAT consulting and advisory services are priced and delivered. Traditionally, the consulting or advisory fee was calculated on the hourly rate. The more hours spent on research, the higher the fee. However, if AI reduces the time required for research and routine analysis, that model may become less sustainable.

Consequently, VAT consulting and advisory companies may instead increasingly offer fixed-fee or subscription-based payment models. This does not mean that consulting will lose value. Technology can allow these companies to serve more clients, analyse larger datasets, and provide services that would previously have been too expensive or time-consuming. Essentially, the pricing model will shift from how many hours can be billed to how much measurable value can be delivered by combining technology with professional expertise.

Human Expertise vs. AI: Where Each Adds Value

The OECD Tax Policy Reforms 2026 notes the shift from traditional VAT compliance toward digitally controlled VAT systems, with non-resident suppliers, online platforms, and electronic transaction data becoming increasingly important to tax administrations. Although AI will play a major role in tax compliance, VAT remains a complex, rules-based field.

More specifically, legislation can contain exceptions, administrative practice can differ between jurisdictions, and the correct treatment may depend on facts that are not immediately apparent from transactional data. In such situations, human judgment remains vital. Consultants need to assess whether an AI-generated interpretation is supported by authoritative sources, understand the commercial context, and communicate the consequences of different approaches to clients.

There are also important questions regarding confidentiality, data security, accuracy, accountability and governance. The OECD has emphasised that AI in tax administration should be trustworthy, transparent and accountable, and that AI should be integrated with human expertise rather than treated as a standalone technology.

For VAT professionals, this means AI governance will become part of professional quality control. Human review may remain essential for material advice, uncertain interpretations, and high-risk transactions.

The Future VAT Consultant

The future VAT consultant will be a hybrid professional, combining deep technical tax expertise with technology fluency and commercial insight. AI will shift their focus from manual compliance and research to high-value advisory, data interpretation, and risk management. Success will belong to those who use AI to work more efficiently while providing the human judgment, client empathy, and ethical oversight that technology cannot replicate.
