State Tax & Revenue Agency Directory

Every state routes business filings through a different set of agencies, under different names. This directory records which office administers sales tax, where you register as an employer, and where the entity itself is filed — plus the base rate, the economic nexus threshold for remote sellers, and how filing frequency is assigned.

These are factual reference pages. Rates and thresholds change; everything here reflects August 2026 and should be verified against the current authority before you rely on it. We name agencies but never link to third-party sites.

White Glove Accounting is a bookkeeping firm — not a licensed CPA firm, public accountancy firm, or registered tax preparer. We keep your books clean so your CPA or tax preparer can do their job.
