Who buys in US accounting & tax, and is there a single national database?
- Who pays for attention here
- Tax software, CPA firms and bookkeeping SaaS pay for intent clicks at tax season; local CPA leads are sold via Yelp and UpCity.
- What a cross-state index adds
- Local directories list firms; the uncovered side is license verification joined with specialization (audit, tax representation) nationally.
- Single national database?
- Partly — federal and state sources each cover part. National merge via NASBA CPAverify moved to ald.nasba.org/search/cpa and returns uniform 403 (robots.txt also 403) as of 2026-09-17 - the machine-readable national verify is shielded. Machine-readable state source exists: WA data.wa.gov 6du3-3h9e (Washington State Certified Public Accountants, 51,490 rows with status/expires/credential number/city, rowsUpdatedAt 2026-09-17; firm registry pzcu-jpab alongside); TX TSBPA lookup (portal.tsbpa.texas.gov/php/fpl/indlookup.php) returns status and expiration as HTML for single-license queries (partial). IRS EA/PTIN directories (RPO API, PTIN holder search, e-file picklist) are 404-deprecated as of 2026-09-17. Buildable per-state starting WA (PO verification, serp 'cpa license lookup' shows 8 state boards in top 10 while the national page ald.nasba.org is 403-shielded)
