Multi-State Sales Tax Filing for Controllers with Expensify
Run multi-state sales tax filing on autopilot inside Expensify.
The Problem
Tracking nexus across 30+ states for Mid-Market Controller clients and filing the right return on the right cadence is a full-time job — and one missed Wayfair threshold triggers back-taxes and penalties.
What We Build in Expensify
AI monitors nexus thresholds, pulls transaction data from NetSuite, prepares state-by-state returns, and logs filings with evidence — nexus risk is tracked in real time, not discovered at audit. Purpose-built for teams running Expensify — uses the native API or agent integration so nothing leaves the system of record.

Integration happens inside Expensify — no data leaves the system, no parallel tool for your team to learn, no license changes.
Human-in-the-loop handoff
Every automation routes exceptions back to a human in Expensify with enough context to act — AI handles the 80%, your team owns the judgment calls.
