DAYJOB: Tax — Benchmarking AI Agents on Professional Tax Work

Surge AI’s DAYJOB: Tax benchmark evaluates AI agents on 50 realistic professional tax assignments spanning eight practice areas, requiring them to analyze complex client records, prepare filings and workpapers, provide advice, identify unasked but consequential issues, and resolve incomplete or conflicting evidence. Built and reviewed by tax experts, the benchmark includes 1,789 files across formats such as PDFs, spreadsheets, tax returns, correspondence, receipts, and transaction records, reflecting the messy documentation common in real tax work. On its leaderboard, Claude Sonnet 5.5 led with a 10.8% pass rate at a stringent 95% rubric threshold, followed by Claude Fable 5.1 and Claude Opus 5.5, highlighting the difficulty of reliably completing end-to-end tax tasks. Illustrative cases showed agents could answer clients’ stated questions while overlooking critical concerns, such as a deadline that could eliminate a homeowner’s capital-gains exclusion or uncertainty over a couple’s legal marital status that could alter retirement-account advice. Unlike benchmarks focused primarily on defined legal questions, return calculations, or information gathering, DAYJOB: Tax emphasizes professional judgment: determining what the actual problem is, investigating overlooked risks, and carrying findings into a complete, defensible deliverable.
