When Should You Exercise NSOs? A Clear Framework for High-Income Tech Employees
You’re Probably Asking the Wrong Question
If you have NSOs, you’re probably asking:
“Should I exercise now… or wait?”
That’s where almost everyone starts.
But here’s the issue.
That’s not actually the decision you’re making.
Because the moment you exercise, a few things happen whether you realize it or not:
You create a tax bill
You take on risk
And you give up some flexibility
So instead of asking:
“When should I exercise?”
A better question is:
“What am I signing up for if I exercise today?”
Once you look at it that way, this starts to get a lot clearer.
Why This Decision Gets Expensive Faster Than People Expect
This usually doesn’t feel urgent at first.
Until it is.
For a lot of high-income tech employees, this turns into a six-figure tax decision pretty quickly.
And when I see this go wrong, it usually looks like one of these:
Someone exercises and owes taxes on value they never actually keep
They think taxes are handled… and then get hit with a big bill later
They wait too long and lose the ability to make a clean decision
This isn’t about trying to be perfect.
It’s about not walking into something you didn’t fully see.
How NSOs Actually Work (Without Overcomplicating It)
At a basic level, NSOs give you the right to buy shares at a set price.
That part’s straightforward.
Where people get tripped up is what happens when you exercise.
What Is the “Spread” in NSOs?
The spread is just the difference between:
What you pay (your strike price)
What the stock is worth today
Quick example:
Strike price: $10
Current price: $50
Spread: $40
Now let’s say you exercise 5,000 shares.
That $40 difference × 5,000 shares = $200,000
Here’s where people misread this:
They think:
“I just made $200,000.”
What actually happened is:
You created $200,000 of taxable income.
That number isn’t telling you what you made.
It’s telling you what’s about to show up on your tax return.
How Are NSOs Taxed? (What Actually Happens at Exercise)
This is where things get a little more technical, but it matters.
When you exercise:
The spread is taxed as ordinary income
It shows up on your W-2
It’s taxed at your marginal rate
For most high earners, that’s:
32–37% federal
Plus state
Why Taxes Feel “Handled”… But Aren’t
A lot of people think:
“Well, taxes were withheld, so I’m good.”
Not quite.
Here’s what’s happening behind the scenes:
Your company usually withholds around 22%
Your actual tax rate is often much higher
So there’s a gap.
Example (This Is Where Surprises Happen)
Spread: $200,000
Withholding: $44,000
Actual tax: ~$85,000+
Now you’re short $40,000+
And the tricky part is:
You don’t feel that right away.
It shows up later, when you have fewer options.
What If the Stock Drops After You Exercise?
This is the scenario people don’t think through.
If the stock drops:
You still owe tax on the original $200,000
You may not be able to sell
You’re covering that difference with cash
So now you’ve got:
A tax bill
Less value
And limited flexibility
That’s a tough spot.
So… Should You Exercise Early or Wait?
This is where I push back a bit.
There isn’t a clean, one-size-fits-all answer.
Because this isn’t just a timing decision.
A Better Way to Think About It: Three Dials
The way I explain this is:
You’re standing in front of a control panel with three dials:
Tax
Time
Risk
And every time you turn one…
The others move.
Try to lower taxes → you might take on more risk
Try to reduce risk → you may have to act sooner
Try to wait → you might lose the opportunity
You can improve one.
But you don’t get to optimize all three at the same time.
That’s the tradeoff.
What Risk Are You Actually Taking When You Exercise?
Once you exercise, the decision shifts.
Now you’re holding the outcome.
And there are a few layers to that.
1. Liquidity Risk
You own shares.
But you may not be able to sell them.
So you’ve taken:
Cash
A tax bill
And turned it into something you can’t easily access.
2. Concentration Risk
Your income already depends on this company.
Now your investments do too.
If things go well, that’s great.
If they don’t, it hits in more than one place.
3. Asymmetry (This One Gets Missed a Lot)
If the stock goes up, you benefit.
If it goes down:
You already paid taxes on the higher value
Getting that back is slow and limited
So the downside tends to stick longer than people expect.
A Simple Framework to Actually Make the Decision
Instead of guessing, here’s how I walk through this with clients.
Step 1: Look at the After-Tax Value
Not just the spread.
What do you actually keep after taxes?
Step 2: Understand Your Time Window
When do your options expire?
What happens if you leave?
Time pressure changes the decision.
Step 3: Be Honest About Risk
How much is tied to one company after you exercise?
What happens if it drops 30–50%?
You don’t need a perfect answer.
Just an honest one.
Step 4: Map Out the Tax Impact
What’s your real tax rate?
What’s being withheld?
What’s the gap?
Plan for it upfront.
Step 5: Decide How to Act
You don’t have to go all in at once.
Full exercise
Partial exercise
Cashless exercise
There’s flexibility here.
Step 6: Decide What Happens Next
This is where most people stop too early.
After you exercise:
Are you holding?
Are you diversifying?
Are you reducing risk?
Have a plan before you make the move.
Where Most High Earners Get Stuck
Most people I talk to understand pieces of this.
They know:
Taxes matter
Risk matters
Timing matters
But they’re thinking about each one separately.
Not together.
So the decision never fully clicks.
