## Summary

A new study involving 12 licensed junior accountants reveals that frontier AI models now outperform humans on medium-length, well-defined accounting tasks. The researchers hired CPAs with an average of five and a half years of experience to complete four realistic month-end close scenarios. In these tests, which required digging through working files to find numbers and perform calculations, AI models were both faster and more accurate than the best human participant.

The study highlights a rapid shift in capability. Just eighteen months ago, the best AI models scored below the average accountant’s 37% mark, but today they ace these same tasks. The authors note that this does not mean accountants are replaceable, as the tasks tested only detail-oriented instruction following and file navigation, excluding broader job duties like client communication and context building. The models were also significantly cheaper, costing more than an order of magnitude less per task criterion than human labor.

The findings suggest substantial productivity gains in accounting are likely in the coming years, even if model progress stalls. The study also critiques current benchmarking practices, arguing that as AI improves, benchmarks are evolving to test tasks that are too complex for any single human to complete, shifting the focus from comparing AI to humans to measuring previously impossible or prohibitively costly work.

## Key points

- Frontier AI models outperformed 12 junior accountants on specific month-end close tasks.
- AI models were faster, more accurate, and more than an order of magnitude cheaper than humans.
- The study notes AI excels at detail-oriented tasks but does not replace full accounting roles.

## Why it matters

This data provides concrete evidence of AI's current economic value in knowledge work, suggesting significant productivity gains in accounting and similar fields, while highlighting the limitations of current human-comparison benchmarks.
