Educational model only — not tax advice. Assumes immediate sale at vest (disqualifying disposition): spread is ordinary income, capital gain is zero. Section 423 ESPP ordinary income is exempt from FICA. Defaults assume an NYC (Queens) single filer in the ~$200k bracket: 32% federal, 6.85% NY state, 3.876% NYC. Adjust any rate to match your situation.
