Equity compensation modeler

Take two earners with equity vesting on top. Each salary is withheld as if it were the only income, the vests at a flat 22%, and none of them see the rest. Together you land in a higher bracket, and the gaps stack into one five-figure shortfall by filing.

The modeler finds yours, from your own numbers.

Your company

Every company’s plan is its own.

Every company’s equity plan works a little differently, and those differences are exactly what decide your outcome. That is why each tool is built for one company at a time, so the numbers reflect your own plan, not a template.

How this is computed

Traceable to the source.

2025-32
Federal brackets and thresholds read from IRS Rev. Proc. 2025-32, not memory.
50
State figures pulled from each state’s own published tables (cross-checked against the Tax Foundation 2026 summary), verified before a state is shown.
Monthly
Every figure re-checked against the published source each month, with a dated report. Drift is flagged, never silently patched.
Directional
Every estimate is directional, meant to inform a conversation, not to file.
