PwC Australia cut partners by 35% and staff by nearly 40% since 2023, yet partner income went up 6%. Meanwhile, the IRS says it just had its “most successful filing season in history” with 25% fewer employees. Fewer people are doing more work than ever. But the accounting profession’s core systems for measuring performance, deciding who to hire, and tracking technology investments were built for a different world.
In a recent episode of The Accounting Podcast, hosts Blake Oliver and David Leary talk about a profession transforming from the inside out. From IRS staffing cuts and Big Four workforce reductions to outdated metrics and licensing bottlenecks, we’re seeing technology race ahead while the infrastructure lags.
Tax Season Success Story (with a Catch)
IRS CEO Frank Bisignano told the Senate Finance Committee that the 2025 filing season was remarkably successful despite the agency losing about a quarter of its staff. The IRS received more than 134 million individual returns, 98% of which were filed electronically. Over 90% of filers got refunds in under 21 days, and the average refund jumped 11% to over $3,400.
The agency credited technology upgrades and AI for the performance boost. Using AI and data analytics to identify underreporting, the IRS sent 500,000 letters that prompted corrections, generating $250 million in additional collections. Enforcement revenue was up 12%, and amended return processing improved from six weeks to just three days. Five noncompliance cases alone brought in $2 billion.
“Just five cases and $2 billion,” Blake noted. “That shows there are some real whales out there when it comes to not paying your taxes.”
But David pointed out an interesting wrinkle. There’s still no confirmed IRS commissioner. Bisignano is serving as CEO without congressional approval, yet Congress seems to have accepted this arrangement with little pushback.
Managing by an Outdated Scorecard
For decades, accounting firms have relied on metrics known as LUMBAR: Leverage, Utilization, Margin, Billing rate, and Realization. These metrics made sense when firms billed by the hour and success meant maximizing billable hours. But as AI compresses work time and firms shift to fixed fees and advisory services, these metrics become misleading.
Douglas Slaybaugh argued in Accounting Today that firms need to track different categories entirely. Instead of hours and billing rates, he suggests measuring:
- Value creation, like advisory revenue as a share of total revenue
- Automation rates
- Redefined leverage, like revenue per employee rather than staff-to-partner ratios
- Organizational health, including “regrettable turnover,” or losing people you wanted to keep
- Client relationships
Blake was blunt about why traditional metrics fail. “If you go over or under on a job based on a job profitability calculation, which is based on hours, it doesn’t actually change anything in the firm because your staff costs are fixed.” When staff are salaried and clients pay fixed fees, being “over budget” on hours is meaningless. “We get so in the weeds,” he added. “We lose the forest for the trees.”
David pushed further, comparing it to Apple before Steve Jobs returned. The company had separate profit-and-loss statements for every product, optimizing each individually while missing the bigger picture. Jobs collapsed it all into one P&L, recognizing Apple as an ecosystem. “Why do you need all these metrics?” David asked. “Focus on the big picture of your firm.”
The shift is already happening at big firms. Client accounting services is the top growth driver for Top 100 firms for the third straight year, with 85% of firms reporting CAS growth. These services now include cash flow forecasting, budgeting, and strategic finance. That work doesn’t fit hourly billing models, yet many firms still try to manage these engagements with traditional utilization targets.
Licensing Rules as a Talent Bottleneck
Current CPA licensing creates what Jack Castonguay of Hofstra University calls a one-way street: firms can hire accountants and train them in AI, but they can’t easily bring in AI experts and train them in accounting.
“The US licensure model almost forces us to start with accountants and teach them AI skills,” Jack wrote in Bloomberg Tax. “It’s good to have accountants who are well versed in AI, but it would be better to also have AI experts trained in accounting. We should create space for both.”
Jack delivered a sharp observation about recent reforms. “We took away the 150-hour moat around the profession, but ultimately built a wall higher for non-accounting majors seeking to become CPAs.”
Blake agreed strongly. “If you can learn accounting theory on your own and pass the CPA exam, why do we require you to go take all these courses? The CPA exam is supposed to test the knowledge. And if you got the knowledge in another way, why do we care?”
The problem plays out in real life. A viewer shared that, despite having a business degree with an accounting minor, Arizona’s requirements and the need for CPA sign-offs create additional barriers for those with non-traditional backgrounds, such as military service.
There’s some progress. Maryland and Nevada joined roughly 30 states adopting alternative CPA pathways that require a bachelor’s degree, two years of experience, and passing the exam, without the 150-hour rule. But David expressed frustration. “We just got past the 150-hour rule, and we’re going to be on this debate and treadmill now for the next five years.”
Meanwhile, big firms aren’t waiting. Beyond PwC Australia’s dramatic cuts, Deloitte US slashed benefits for non-client-facing staff, halving parental leave from 16 to 8 weeks, cutting PTO by five days, and eliminating the $50,000 adoption and surrogacy benefit.
“What if this is just a way to get people to quit so you don’t have to lay them off from AI later on?” David wondered. The timing makes sense. While 51% of workers said they’d quit over return-to-office mandates in 2025, that number has crashed to just 7% in 2026. Workers are scared, and employers know it.
Betting on AI Without Measuring Results
A Thomson Reuters survey of 1,500 professional services respondents across 27 countries revealed only 18% track AI’s return on investment. Forty-two percent don’t measure at all, and 40% aren’t sure whether they do.
“Pretty much 80% aren’t tracking the return on their AI spend,” David said.
Those who do measure focus on the wrong things. Seventy-seven percent track cost savings, 64% track employee usage, but only 26% track client satisfaction, 23% track revenue growth, and just 17% track new business generation.
“They’re not tracking the correct metrics in their firms,” David noted. “This is not an accounting firm problem. This is professional services.”
The risks of poor AI implementation are real. Deloitte faces investigation in Newfoundland and Labrador after a resident discovered its $1.6 million healthcare report contained AI-generated fake citations. This is at least the third Big Four AI incident.
“They’re selling AI consulting services,” David said, “and then they prove they can’t do it themselves.”
The measurement problem extends beyond AI. Annual recurring revenue (ARR), the metric driving virtually every subscription company’s valuation, has no GAAP definition or standardized calculation. Companies define it however they want. A startup CEO recently made headlines for simply making up ARR numbers.
“If I were in charge of accounting standards, SaaS metrics is the first project I would have FASB do,” Blake said. “It’d be the best thing we could do for tech companies.”
The Path Forward
The accounting profession faces a challenge. The technology works, but the supporting infrastructure hasn’t caught up. Firms still manage by metrics that don’t reflect value creation. Licensing rules block the tech talent firms desperately need. And most organizations aren’t even measuring whether their AI investments pay off.
PwC Australia’s CEO, Kevin Burrowes, put it bluntly: “The future is fewer people doing the same amount or fewer people doing more.” Firms that don’t rebuild their internal systems to match this reality risk falling behind in a rapidly transforming profession.
