Option Exercises Employees Actually Understand
Exercising options means real money and real tax, and most employees fly blind. Fintra shows the cost, the tax by grant type, and the outcome - then updates the cap table.
What option exercise covers
Fintra runs the exercise flow: it checks how many vested options are exercisable, shows the exercise cost and an estimated tax impact based on the grant type (ISO vs NSO) and the spread to fair market value, records the exercise, and updates the cap table and holdings - so the equity picture stays correct after exercise.
- Eligibility from live vesting
- Exercise cost and estimated tax by grant type
- ISO vs NSO treatment surfaced clearly
- Cap table and holdings updated on exercise
The tax employees need to see
| Grant type | At exercise | Watch-out |
|---|---|---|
| ISO | No ordinary tax, but AMT on spread | AMT can be large |
| NSO | Ordinary income on spread | Withholding due |
| RSU | Income at vesting/settlement | Not an exercise decision |
Clarity prevents costly mistakes
Connected to equity and payroll
- Reads vesting and grant terms from the cap table
- Updates holdings and fully-diluted ownership
- NSO withholding can flow to payroll
Frequently asked questions
What happens when an employee exercises options?
They pay the exercise cost (strike price × shares) to convert vested options into shares. Fintra checks eligibility from live vesting, shows the cost and an estimated tax impact by grant type, records the exercise, and updates the cap table and holdings.
What’s the tax difference between ISOs and NSOs at exercise?
NSOs generate ordinary income on the spread at exercise (with withholding), while ISOs have no ordinary tax at exercise but the spread can trigger alternative minimum tax. Fintra surfaces the grant type and an estimate so employees aren’t blindsided - this is an estimate, not tax advice.
Does exercising update the cap table?
Yes - an exercise converts options to shares and updates holdings and fully-diluted ownership on the cap table automatically, so your equity records stay correct without a manual entry.
Can employees model an exercise before committing?
Yes. They can see exercisable quantity, cost, and estimated tax before deciding, which - combined with the exit-waterfall view - helps answer whether exercising makes sense at the current valuation.
