By April, that optimism had vanished.

Accountant attitudes closed the season slightly negative, around -1 to -1.8, marking a swing of more than 30 points in four months.

It was one of the sharpest same-season reversals in the Barometer’s 24-year history, and it followed a pattern practitioners have seen before: expectations rising in the fall, then breaking under the weight of the season itself.

The difference in 2026 was the speed—and the causes.

Kenji Kuramoto: Basis Moves to Close AI’s Biggest Gap

When accountants and AI agents work side-by-side

“The future of the profession is accountants and agents working together,” Kuramoto says.

For CPA Trendlines

“Managing partner-in-residence” is not a standard role in accounting, and that was the first point of friction when Kenji Kuramoto was asked to explain his new job at Basis, the accounting AI agent company. What does that actually mean?
