How it works

Three inputs. Results in under 30 seconds.

2
Add remote employee locations and salary
Add each state where you have remote workers. Optionally enter an average salary to unlock per-state SUTA cost estimates. The tool maps your full compliance footprint as you type.
3
Review, act, and export
Get a risk-tiered state breakdown, a reciprocity analysis, trailing nexus windows with exact dates, and a prioritized compliance roadmap. Export the roadmap to PDF for your team or advisor.
