PwC's latest global financial results reveal a notable development in the professional services market: Tax and Legal Services have emerged as the network's fastest-growing business line, outperforming both Advisory and Assurance.
For the financial year ended 30 June 2026, PwC reported aggregate global gross revenues of US$60.2 billion, representing growth of 5.7% in US dollar terms and 3.5% at constant exchange rates. Within that performance, Tax and Legal Services recorded 6.3% like-for-like growth, supported by demand for international tax compliance, regulatory reporting and technology-enabled tax solutions.
Tax and Legal Services Outperform Advisory and Assurance
According to PwC's financial results published on 19 October 2026, all three principal service lines recorded positive revenue growth. However, the pace of expansion differed considerably.

Tax and Legal Services generated approximately 23% of PwC's global gross revenues, compared with around 43% from Advisory and 34% from Assurance.
The tax and legal business also recorded an 8.6% increase in reported US dollar revenues against adjusted FY2025 comparatives.
Importantly, PwC's figures combine tax and legal activities. The network does not disclose a separate global tax-only revenue figure in this announcement.
Pillar Two and International Tax Complexity Support Demand
One of the principal factors behind the performance was continued demand for assistance with increasingly complex international tax obligations.
PwC specifically identified Pillar Two, cross-border taxation and tax operating models as areas of particularly strong client demand.
The implementation of the Organisation for Economic Co-operation and Development (OECD) global minimum tax framework has introduced additional reporting and compliance requirements for multinational groups.
For affected businesses, these obligations can involve coordinating financial and tax data across jurisdictions, assessing effective tax rates, calculating potential top-up taxes and preparing the required disclosures.
Beyond Pillar Two, multinational enterprises are also responding to changes in global trade, evolving tax regulations and cross-border reporting obligations.
These developments create demand not only for technical tax advice but also for ongoing compliance support, process redesign and stronger tax governance.
PwC's results suggest that the increasing operational complexity of taxation is becoming an important commercial driver for professional services firms.
Tax Operating Models and Technology Become Growth Areas
Another notable element of PwC's announcement is the emphasis on how companies organise and deliver their tax activities.
PwC highlighted demand for assistance with tax operating models as businesses seek to balance compliance requirements, efficiency and governance.
This reflects a broader shift in the role of external tax advisers.
Traditional advisory work remains important, but multinational tax departments increasingly require support with recurring processes, data management and technology-enabled delivery.
PwC identified several capabilities under development or expansion, including:
- Tax data aggregation and project management platforms.
- Artificial intelligence (AI)-enabled tax research agents.
- Data-driven service delivery models.
- Technology-enabled compliance and governance solutions.
The development of these capabilities suggests a move towards more integrated tax services combining technical expertise, technology and operational execution.
For corporate tax departments, the potential implications extend beyond outsourcing individual tax filings. Technology-enabled advisory models may increasingly influence how tax functions allocate responsibilities between internal teams, external providers and automated systems.
PwC Invests US$3 Billion in AI and Technology
Technology investment was another major feature of the FY2026 results.
PwC reported US$3 billion in network-wide investment in capabilities, particularly AI and technology, alongside AI training for more than 330,000 people across the network.
The investment included the initial rollout of PwC One, an AI-enabled platform designed to integrate the network's knowledge, professional standards and expertise.
PwC also continued developing its AI-native assurance platform and technology solutions supporting tax data aggregation, project management and automated workflows.
While the financial results do not disclose how much of the US$3 billion investment was allocated specifically to tax technology, the explicit reference to tax platforms indicates that tax transformation forms part of the network's broader technology strategy.
Regional Performance: Asia Pacific Leads, EMEA Slows

Asia Pacific delivered the strongest growth, with PwC identifying India, Japan and South Korea among markets performing particularly well.
The Americas recorded 4.6% growth, supported by markets including the United States and Brazil.
Europe, the Middle East and Africa (EMEA) experienced much slower growth at 0.7%, although PwC highlighted stronger performances in Germany, Greece and Spain.
These figures represent overall regional revenues rather than regional tax-specific performance. Consequently, they do not establish which geographic markets contributed most to the expansion of Tax and Legal Services.
What the Results Indicate for the Tax Advisory Market
PwC's FY2026 performance provides several insights into the evolving tax professional services market.
First, regulatory complexity remains a significant source of demand. International tax developments, including Pillar Two and cross-border reporting requirements, continue to create work for advisers even when other professional services markets experience slower growth.
Second, tax technology is becoming increasingly integrated into advisory delivery. Investment in AI, tax data platforms and automated workflows indicates that professional services firms are developing capabilities beyond traditional technical advice.
Third, tax operating model transformation is becoming commercially important. Companies are increasingly assessing how tax activities should be organised, governed and delivered, creating opportunities for services combining tax expertise with operational and technological capabilities.
Finally, the relative performance of Tax and Legal Services suggests resilience in demand for compliance-driven services. Unlike certain discretionary consulting projects, many tax obligations must be addressed regardless of broader economic conditions.
However, PwC's financial announcement does not quantify the individual contributions of Pillar Two, AI-enabled services or other tax offerings to revenue growth. Their respective commercial importance cannot therefore be measured directly from the published figures.
Outlook: Tax Compliance and Technology Convergence
PwC's results highlight an increasingly close relationship between tax advisory, regulatory compliance and technology.
For multinational enterprises, tax functions are facing growing expectations to manage complex reporting obligations while improving efficiency and governance.
For professional services firms, this creates opportunities to develop more scalable delivery models, supported by AI, data management and automated processes.
The key question for the coming years is whether technology investment will primarily increase the efficiency of existing tax services or create additional sources of revenue through new delivery models.
PwC's FY2026 performance demonstrates that, at least for this reporting period, Tax and Legal Services have been a stronger growth engine than the network's other major business lines.
