TaxBase — Source-First Tax Research

tb.tax Observed source

Editorial interest 74/100 Selection signal · not a rating of the site

A proposed research workspace for tax professionals that connects questions to organized, citable U.S. tax guidance.

Landing page captured for the 2026-09-04 issue.

Field notes

The page describes a four-stage workflow: ask a tax question, review source passages and context, save findings, then return to them as work continues. Its sample research surface points to IRS Publications 587 and 334 and emphasizes tax-year organization rather than isolated answers. Proposed workspaces range from individual research to firm administration, but the page says payment processing is not yet connected to production.
