Equity Compensation Strategy
ISO & NSO Stock Option Planning
Options give you a choice about when to create taxable income. That choice is where most of the value, and most of the mistakes, live.
Stock options give you the right to buy shares at a fixed strike price, and the tax outcome depends almost entirely on when and how you exercise. Incentive stock options (ISOs) are the more favorable form on paper: no regular income tax at exercise, and long-term capital gains treatment on the full gain if you hold the shares at least two years from grant and one year from exercise. The catch is that the spread at exercise, the difference between the share price and your strike, counts as income for the Alternative Minimum Tax, which can produce a large bill on shares you have not sold. Non-qualified stock options (NSOs) are simpler. The spread at exercise is taxed as ordinary wages, withheld like a bonus, and future growth is a capital gain.
The decisions stack up quickly. Exercise early or wait. Exercise and hold, exercise and sell, or use a cashless exercise. File an 83(b) election on early-exercised shares. Fund the exercise with savings, a loan or a tender offer. Manage a post-termination window when you change jobs. We model each path against your tax picture and your cash, at private and public companies alike, so the option to choose actually works in your favor.
What we handle
- ISO versus NSO tax treatment, and what each means for your regular tax, AMT and payroll withholding
- AMT modeling before each ISO exercise, including how many shares you can exercise before crossing into AMT and how to recover the AMT credit in later years
- Qualifying versus disqualifying dispositions, and the two-years-from-grant and one-year-from-exercise holding periods that separate them
- Early exercise and 83(b) elections at early-stage companies, when the spread is small or zero
- Exercise-and-hold versus exercise-and-sell versus cashless exercise, compared in after-tax dollars
- The $100,000 ISO limit: how much can first become exercisable as ISO in a calendar year, and the NSO treatment of the excess
- Post-termination exercise windows, including the three-month rule that governs ISO status after you leave
- Exercise financing and liquidity risk at private companies, plus tender offers and secondary sales as ways to realize value
How we work together
- 01
Inventory
We gather your option grants, strike prices, vesting schedules, exercise history and any 409A valuations, then lay out what is vested, what it would cost to exercise and what the spread is today.
- 02
Modeling
We project regular tax and AMT under several exercise scenarios across this year and next, including the effect on your cash, your holding periods and your exposure to a single company.
- 03
Plan and follow-through
You receive a written exercise plan with amounts, timing and a funding approach. We revisit it before each exercise, at year-end and ahead of any tender offer, job change or IPO, and hand your CPA the details needed for AMT and basis reporting.
Why work with an independent advisor
Option decisions attract advice from people who benefit when you act: lenders that finance exercises, brokers that execute cashless sales and platforms that hold your shares. We do not earn commissions, referral fees or financing spreads on any of it. Our only stake is whether the exercise is right for your taxes, your cash and your goals, and we are free to say that waiting is the best move. We also coordinate directly with your CPA on AMT and basis reporting rather than leaving you to translate.
Frequently asked questions
What is the difference between ISOs and NSOs for tax purposes?
With NSOs, the spread at exercise is ordinary income reported on your W-2, with tax withheld, and later growth is a capital gain. With ISOs, there is no regular income tax at exercise, but the spread is included in income for the Alternative Minimum Tax. If you hold ISO shares at least two years from grant and one year from exercise, the entire gain from strike to sale price is a long-term capital gain. Sell earlier and the spread becomes ordinary income instead, in what is called a disqualifying disposition.
How does the AMT work when I exercise ISOs?
The AMT is a parallel tax calculation. Exercising ISOs adds the spread to your AMT income even though you have not sold anything. If the AMT calculation produces a higher tax than the regular calculation, you pay the difference, in a year when you may have received no cash from the shares. Part of that extra tax becomes a credit you can recover in future years when your regular tax exceeds AMT. We model how many shares you can exercise before the AMT kicks in and track the credit so it is not lost.
Should I exercise early, before my options vest?
Some companies allow early exercise of unvested options. Combined with an 83(b) election filed within thirty days, this can mean paying little or no tax at exercise when the spread is small and starting the capital gains holding period right away. The risks are real: you pay the strike price in cash for shares you may forfeit if you leave, and the company may never become liquid. Early exercise tends to make the most sense when the strike is low and your conviction is high.
What is the best way to exercise: hold, sell immediately or cashless?
It depends on your tax bracket, your cash and how much of your net worth is already tied to the company. Exercise-and-hold preserves the chance of long-term capital gains but requires cash and carries AMT and price risk. Exercise-and-sell locks in the value and pays tax as ordinary income. A cashless exercise sells just enough shares to cover the strike and tax. We compare these in after-tax dollars for your situation rather than following a rule of thumb.
I am leaving my company. How long do I have to exercise?
Check your plan document. Many plans give you ninety days after departure, though some offer far longer. For ISOs, the tax code is stricter: options exercised more than three months after leaving lose ISO treatment and become NSOs even if the plan allows it. Exercising at departure often requires cash for both the strike price and the tax, so we plan the funding and timing before you give notice whenever possible.
My company is private. How can I turn options into money?
At a private company, the typical routes are a company-sponsored tender offer, a secondary sale to an approved buyer, or waiting for an IPO or acquisition. Each has tax consequences. A tender offer priced above the current 409A valuation, for example, may cause part of the proceeds to be treated as compensation rather than capital gain. Exercising with borrowed money adds risk if the liquidity event never comes. We help you weigh these paths alongside your RSU and RSA planning and your overall equity compensation plan.
