Sales tax services for CPA's and Bookkeepers
Offload sales tax, keep your focus.
We handle multi-state sales tax for your clients — assessment, registration, filing, and audit support — so your firm stays focused on the work that grows the practice.
Every State, it's own rules
Since the 2018 Wayfair decision, economic nexus thresholds differ state by state — and they keep changing.
Hours you can't bill
Registrations, filings, and deadlines pile up and quietly eat into time meant for higher-value work.
Risk you're left holding
Missed thresholds and late filings expose your clients — and your firm's reputation — to costly exposure.
The Challenge
Sales tax pulls firms off course
Your clients have outgrown their DIY tax tools — but they aren't ready for the price tag of enterprise software. That gap lands on your desk, and multi-state sales tax is a fast-moving, high-risk distraction from the advisory work you do best.

NexAssess
We pinpoint exactly where your client has triggered economic or physical nexus, so you know their real multi-state obligations.
