Deloitte has released its latest annual revenue numbers, reporting $74.5 billion in global revenue for fiscal year 2026, once again putting the Big Four firm among the largest professional services organizations in the world.

The results, released September 24, cover Deloitte’s fiscal year ended May 31, 2026. Revenue increased 5.7% in U.S. dollar terms and 3.8% in local currency compared with the prior year. Deloitte rounded the headline increase to approximately 6%.

The firm also continues to get bigger from a headcount perspective. Deloitte said its global workforce has expanded to nearly 500,000 employees and professionals worldwide.

Deloitte’s 2026 Revenue Numbers

The major numbers from Deloitte’s latest announcement are:

  • Global revenue: $74.5 billion
  • FY2025 revenue: $70.5 billion
  • Dollar revenue growth: 5.7%
  • Local-currency growth: 3.8%
  • Global workforce: Nearly 500,000 people
  • FY2025 workforce: More than 470,000 people

Deloitte generated approximately $4 billion more revenue than it did in FY2025, when the firm reported $70.5 billion in global revenue. Last year’s revenue had grown 4.9% in U.S. dollar terms and 4.8% in local currency.

That creates an interesting distinction in the 2026 results. Currency movements helped Deloitte’s reported dollar revenue growth accelerate, but on a local-currency basis, growth actually slowed from 4.8% in FY2025 to 3.8% in FY2026.

Deloitte Is Approaching 500,000 Employees

Perhaps just as notable as the revenue figure is Deloitte’s headcount.

The firm now says it has nearly 500,000 people across more than 150 countries and territories. A year earlier, Deloitte reported having more than 470,000 people globally.

Because Deloitte does not provide an exact FY2026 employee number in its revenue announcement, it isn’t possible to calculate the precise increase. However, the disclosures indicate that the organization’s workforce has grown by roughly tens of thousands of people over the past year.

That continued hiring is particularly notable given the amount of attention the Big Four firms have placed on artificial intelligence and automation.

Rather than reporting a shrinking global workforce as AI adoption accelerates, Deloitte is entering FY2027 with its total workforce close to the half-million mark.

Consulting Growth Slowed

One of the biggest stories inside Deloitte’s numbers is the slowdown in its Technology & Transformation business.

Technology & Transformation revenue grew just 2.5% in local currency during FY2026, down from 4.7% growth in FY2025. Deloitte’s Strategy, Risk & Transactions business also slowed, growing 4.4%, compared with 5.5% a year earlier.

The results suggest that the enormous amount of attention being paid to AI hasn’t automatically translated into equally enormous consulting growth.

The Financial Times also highlighted the weakness in technology consulting when reporting on Deloitte’s results, noting that slower growth in the firm’s largest division weighed on overall revenue growth.

Other parts of Deloitte performed better.

Audit & Assurance revenue increased 5% in local currency, compared with 3.8% growth in FY2025.

Tax & Legal grew 5.8%, improving from 5.4% growth during the prior year.

So while technology consulting slowed considerably, Deloitte’s more traditional audit and tax businesses actually accelerated.

Asia Pacific Was Deloitte’s Fastest-Growing Region

Deloitte also disclosed significant differences among its geographic regions.

Asia Pacific recorded the strongest growth, with revenue increasing 7.5% in local currency. EMEA grew 3.5%, while the Americas grew 3.2%.

That represents a significant shift from FY2025, when the Americas was Deloitte’s fastest-growing region at 7.1% and Asia Pacific grew 4.9%.

The slower Americas growth is therefore another important part of Deloitte’s FY2026 results.

Deloitte Continues to Spend Heavily on AI

Deloitte isn’t backing away from its AI strategy despite slower growth in technology consulting.

The firm said it plans to invest $3 billion through 2030 to modernize its operations and delivery capabilities and develop new technology-enabled services.

Deloitte specifically highlighted agentic AI, its Zora AI platform developed with NVIDIA, AI infrastructure services and additional automation across audit, tax and consulting.

At the same time, Deloitte is investing heavily in training its human workforce. The firm spent nearly $700 million on learning and development in FY2026 and delivered more than 23 million hours of formal training. Much of that training is focused on areas including AI, cloud computing and cybersecurity.

Deloitte Keeps Getting Bigger — But Growth Is Uneven

At $74.5 billion of annual revenue and nearly 500,000 people, Deloitte enters FY2027 at an enormous scale.

However, the underlying numbers show a more complicated picture than the headline revenue record alone.

Overall revenue continues to rise, Audit and Tax growth accelerated, and Deloitte added significantly to its global workforce. At the same time, local-currency growth slowed, Technology & Transformation growth dropped to 2.5%, and growth in the Americas fell sharply from the previous year.

For a Big Four industry increasingly focused on what artificial intelligence will mean for consulting demand and professional-services employment, Deloitte’s FY2026 results provide an interesting early signal: AI is changing where the firm is investing and how it delivers work, but so far it hasn’t stopped Deloitte’s global workforce from expanding toward 500,000 people.
