Agents in Tax accounting

Surge AI's tax benchmark: the best agent passes 10.8% of 50 professional assignments

Surge AI's DAYJOB: Tax tests agents on returns, workpapers and advice across eight areas of tax practice. Claude Sonnet 5.5 leads at 10.8% pass@1, ahead of Claude Fable 5.1 at 9.6% and Claude Opus 5.5 at 9.2%.

Why it matters: Surge says agents can miss issues clients never raised, like a looming sale deadline. A pass needs 95% of rubric criteria, and professional judgment remains out of reach.
