Why does one engineer moving from SF to Austin trigger a three-month payroll mess?

When a remote employee moves from California to Texas mid-quarter, payroll scrambles for new state withholding, unemployment registration, and reciprocity, often a quarter late and with penalties.

Who has it: Payroll manager or HR ops at a 50 to 500 person fully remote US company.

Payroll teams describe learning months late that a remote employee moved states, having withheld the wrong state's tax, then facing back payments, new registrations, and a PEO that charges per state and will not help.

Existing players

Gusto, Rippling, Justworks · Handle current-state withholding, do not detect undisclosed moves, no nexus analysis.
Mosey · State compliance tracking, no payroll write-back, no self-attestation flow.
PEO services (TriNet, Insperity) · Charge per state, slow registration, no proactive move detection.

What they are missing

An agent that runs quarterly geofence and IP-based move detection (with consent), prompts self-attestation, auto-registers for unemployment and withholding in the new state, files retroactive amendments, and updates payroll, all from one approval.
