W-2 Box 12 Code V after NSO exercise: what it means and what to do

Box 12 Code V identifies NSO exercise spread included in Box 1 — do not report it again as separate wages.

You exercised nonqualified stock options and your W-2 Box 12 shows Code V with a dollar amount — or HR said the spread is on your W-2. You want to know how Code V relates to Box 1 wages, whether you report it again on your return, and how it differs from RSU vest reporting.

In plain terms

IRS instructions define Box 12 Code V as income from the exercise of nonstatutory stock options included in Boxes 1, 3, and/or 5. The spread at exercise is ordinary wage income already counted in Box 1 — Code V is a breakout label, not separate taxable income. Do not add Code V on top of Box 1 on your tax return. wages typically appear in Box 1 without a Code V line — Code V is specific to exercises.
