Someone at your company has told you to exercise early. Probably at lunch, probably casually, in the tone people use for things that are obvious. Before the next 409A. While the spread is small. You will thank yourself later.
They may be right. They are also not in a position to say. They do not know how much cash you have, what your tax picture looks like this year, or what happens to your household if the money never comes back.
Because here is what that lunchtime advice is actually asking you to do. Take money you have today, that you could spend, invest, or leave in savings, and hand it to your employer in exchange for shares you cannot sell, at a company whose outcome is unknown, in a transaction that may generate a tax bill payable in cash next April whether or not anything becomes liquid.
That may still be a good decision. It is not a small one, and it is not primarily a tax decision, which is how it is almost always presented.
Two different things get called early exercise
The phrase covers two situations that behave differently, so settle which one you are in before anything else.
The first is exercising options that have already vested, ahead of any liquidity event. You have the right to buy the shares, you have not bought them yet, and you are choosing to buy them now rather than wait.
The second is exercising options that have not vested yet, which only some plans allow. Where a plan permits it, you buy shares subject to a repurchase right that lapses on the original vesting schedule, and the election that typically accompanies it is the 83(b) filing, which we covered in the piece on the two-page form that changes the tax on unvested shares.
Whether your plan permits early exercise at all, and on what terms, is in your plan document and your grant agreement. Do not assume from what a coworker did. Plans differ, grants under the same plan can differ, and the answer is written down.
The cash is the first question, not the last
Start with the money, because it is the part people underestimate and the part that is not theoretical.
Exercising costs the strike price times the number of shares, paid in actual dollars, generally at the time you exercise. That is money leaving your household for an asset you cannot sell and cannot value with any precision.
The numbers below are invented for illustration. They are not a recommendation, and they are not anyone’s situation.
An employee holds forty thousand vested options at a two dollar strike. Exercising all of them costs eighty thousand dollars in cash, before considering any tax at all. If the current 409A price were twelve dollars, the spread would be four hundred thousand dollars, and depending on what type of options these are, that spread can carry a tax consequence in the year of exercise.
Notice what happened there. A decision framed as tax optimization required eighty thousand dollars up front and potentially created a second cash obligation on top of it, for an asset that produced no cash at all.
This is why I treat early exercise as a cash flow question first. Not because the tax does not matter, but because the tax analysis is worthless if writing the check leaves your household without a reserve. We laid out how to think about the order in which money should be deployed in the article on the sequence of accounts, and an illiquid private stock purchase belongs nowhere near the front of that sequence for most households.
What the tax can do, in general terms
I am going to describe mechanics in general terms, because the specifics depend on what you hold, what your income looks like this year, and where you live, and because none of it can be applied to you from here.
If you hold nonqualified options, exercising generally creates ordinary income on the spread between the strike and the fair market value at exercise. That income typically flows through payroll with withholding. It is taxable in the year of exercise regardless of whether you can sell the shares.
If you hold incentive stock options, the spread at exercise is generally not ordinary income, but it can be an item in the alternative minimum tax calculation, which is its own parallel system with its own rules. That is the mechanism behind the stories you have heard about people owing large sums on paper gains they never realized.
California layers its own tax treatment on top of the federal outcome, which is part of why the arithmetic here is harsher for Bay Area households than the national commentary suggests, as we covered in the piece on why the Bay Area high earner’s tax situation is different. If you are unsure which type of options you hold, that is the first thing to establish, and we walked through it in the article on which kind of options you actually have.
None of the above tells you what you would owe. Nobody can tell you that without your full return. Take the actual numbers, from your actual grant, to a CPA who has handled private company equity, before you exercise rather than after.
The risk is not that the stock goes down
Ask most people what the risk of early exercise is and they will say the shares could lose value. That is true and it is not the sharpest version of the risk.
The sharper version has three parts.
The first is that private company shares can go to zero, and unlike a public position, there is no point along the way where you can decide to get out. There is no market. You hold until there is an outcome, and the outcome may be nothing.
The second is that the tax can come due even when the money never does. A tax obligation created by exercise is generally payable in cash on the normal schedule, whether or not the shares ever become sellable. That is the part that turns a bad outcome into a household problem rather than a disappointment.
The third is timing you do not control. Companies stay private longer than people plan for, and the stretch between writing the check and any chance of liquidity can run years. During those years the money is not funding your reserve, is not diversified, and is not available in the year one of you loses a job.
The tax code contains mechanisms intended to reconcile some of this over time when an alternative minimum tax liability is triggered. Whether any applies to you, and what it would recover and when, is a question for your CPA and not a reason to treat the risk as smaller than it is.
The pressure that makes this feel urgent
Two things push people into this decision faster than they would otherwise move.
The first is the post-termination exercise window. Many plans give a departing employee a limited period to exercise vested options or lose them. If you are leaving, that window can turn a considered decision into a deadline, which is exactly the condition under which people write checks they should not write.
The second is the assumption that the 409A only goes up, so exercising sooner is always cheaper. Valuations can move in either direction, and a lower future 409A is not a rescue if the company is worth less, as we covered in the recent piece on what a private company equity number actually measures.
Urgency is real when the window is real. Read your plan document, find your actual post-termination period and your actual expiration dates, and let the real deadline set the pace rather than a rumor at lunch.
The questions that make this decidable
You do not need an opinion from me. You need five things in front of you.
- From your plan document and grant agreement: whether early exercise is permitted, your strike price, your vesting schedule, your expiration dates, and your post-termination exercise window.
- From your equity administrator: the current 409A price per share and the date it was set.
- From your own records: the total cash the exercise would require, and what percentage of your accessible savings that represents.
- From your CPA, before you act: what the exercise would do to your return this year, under your actual income, including any alternative minimum tax exposure.
- From a conversation with your spouse: whether your household could write that check, never see the money again, and continue on without changing anything that matters.
If the answer to that last one is no, the tax analysis does not rescue the decision. It just makes an unaffordable transaction slightly more efficient.
Early exercise is a purchase, not a tax strategy. Before you optimize the tax on it, decide whether you want to own the asset at that price, with that much of your cash, for an unknown number of years.
