Tax Research Software for CPAs
The right research tool does more than produce a fast answer. It shows the authority behind the answer, makes the source easy to verify, and fits the way your firm already works.
For CPAs, EAs, tax attorneys, and small firms · Primary sources · Source-linked results
The Standard
AI can make tax research feel fast. For client work, the question that matters is simpler: can you trace the conclusion back to the governing authority and verify it yourself? A polished explanation with an unreliable citation is not a research conclusion.
Evaluation Criteria
01
Ask which authorities the software can retrieve—not just what it claims to know. For federal work, that includes the IRC, Treasury Regulations, and current IRS guidance.
02
A source is the handoff from a useful first pass to defensible professional review. The researcher should be able to read it in context.
03
The useful tool lets you state the issue clearly, locate the controlling text, and follow the needed sources without losing context.
04
Know which sources are included, which are limited, and when the work requires a different research tier.
