The model
01
Projected total federal tax, recomputed on every change.
02
Withholding plus estimates against the safe-harbor line.
03
Cash parked so April is a transfer, not a scramble.
How it works
04
Salary, withholding, a vest or a sale. Two minutes, in your browser.
05
Each event recomputes the estimate and the safe-harbor position.
06
A vest that pushes you into a new bracket, a safe-harbor gap forming. That is when you hear from it.
Planned for March 2027
