One place to understand where professional services get taxed — and to catch what changes, every business day.
Most U.S. states do not tax professional services — but a growing minority do, and the categories moving fastest (IT, data, and staffing services) are the ones businesses most often get wrong. This site keeps two things in one place:
A comprehensive, plain-English synopsis of how sales tax applies to professional services across the states. Read it once and you'll understand the topic soundly — even if it's brand new to you.
Each business day we scan the state revenue departments and the major tax publishers and record what changed. One tab for today, plus a tab for each of the last four business days.
Seven pages in all — this home page, the baseline, and five business-day briefs.
The full landscape as of Jul 23, 2026: how states tax services, which states tax professional services, the specific service categories at risk, and the mechanics (tax base, sourcing, nexus) that decide taxability.
