工程师的股票期权指南
An Engineer’s guide to Stock Options

导读
这是一篇写给工程师的股票期权入门指南，解释期权的基本机制、行权以及相关的估值和税务问题。文章想帮助员工理解创业公司期权在薪酬中的意义，但评论指出它没有充分区分 ISO/NQO 等关键税务细节。
为什么经久不衰：它用通俗框架把期权、行权和税务风险讲清楚，而且随着 pre-RSU、远程雇佣等新情境出现，仍不断被拿来讨论，所以多年后依然值得读。

期权税务（NQO/ISO、AMT、83(b)）决定经济风险，早行权有税优也有现金风险。
期权价值与税务密不可分。NQO 行权时按差价计入普通收入；ISO 的差价可能触发 AMT，反而带来大额税负。降低这种风险的办法之一是尽早行权，但你要用现金承担公司长期价值不确定的风险；未 vest 的期权通常还需授予协议特别允许提前行权。若可提前行权，可提交 83(b)，持有至少两年后可能类似限制性股票，直到出售才再纳税并享受长期资本利得税率。

Really nice write-up explaining stock options. A few added thoughts sparked by some of the comments already made in this thread and otherwise: 1. The value of options is inextricably linked to tax and you need to understand the tax basics in evaluating the economic risks and benefits of holding and exercising any kind of option. With NQOs, you are taxed on the spread as ordinary income on the date of exercise (meaning, on the difference between what the stock is worth and what you pay to exercise). With ISOs, the value of the spread becomes subject to AMT and you can wind up paying large taxes that way in spite of the supposed tax benefits of ISOs. The way to avoid having a large spread subjecting you to such tax risks is to exercise as early as possible before the company value goes up much but you then need to take the economic risk associated with having to pay hard cash for stock whose long-term value is highly uncertain. Moreover, early exercise is not possible if your options haven't vested unless you specifically get an early exercise privilege as part of your grant. With an early exercise privilege, and particularly if the grant is made for a bargain price, you can early-exercise, file an 83(b), and (as long as you hold the stock for at least 2 years) get the equivalent of a restricted stock grant by which you pay no further tax until you eventually sell the stock at a liquidation event. In that case, you are also taxed at the lower long-term capital gains rates. Of course, in the early-exercise scenario, you do not get to bypass vesting and your shares remain subject to their original vesting requirements and can thus be forfeited in whole or in part if those requirements are not met. But early exercise does provide an elegant solution to most of the tax risks associated with options provided you are willing to assume the economic risks of paying for the stock up front. 2. Other than the early-exercise scenario, 83(b) elections are not required for option grants. Under 83(a) of the Internal Revenue Code, any service provider who gets property in exchange for services is taxed at ordinary income rates on the value of the property received. For example, if you do work for a startup and are paid in stock when you complete the deliverable, you are taxed on the value of the stock received. You are taxed on the value of that stock as it exists as of the date you receive it in payment for such services. So, if you do development work tied to a milestone, and you meet that milestone, and you get 100,000 shares for the work, you would be taxed on, say, the $1.00/sh that the stock is worth on the day six months or a year (or whatever) out when the milestone is met, and not on the $.01/sh that it was worth when the contract terms began. In contrast to this performance-based form of incentive, let us say that you get a time-based incentive by which you buy the stock up front for a nominal price but you must earn it out over time. With such a time-based performance incentive, which is what is called "restricted stock", you own the stock up front and you pay no tax at the time of purchase in the normal case where the amount you pay for it equals its fair value on the date of the grant. Because the stock must be earned out as part of a continuing service relationship, and is hence subject to a "substantial risk of forfeiture", there is a very important technical question under section 83(a) on what the date is on which you are deemed to have received the stock in exchange for your services. Well, the default rule under 83(a) is that you receive it on the date it is no longer subject to a substantial risk of forfeiture and that then becomes the relevant date on which the value of the stock is measured for purpose of computing the taxable service income on which you must pay tax. So, if you get your 100,000 share grant at $.01/sh, and you pay $.01 share, you pay no tax at inception. But, as that grant vests at, say, a monthly ratabl…
提前行权配合 83(b) 可锁定资本利得时钟，但承担现金和公司失败风险。
我经历过一种“pre-exercise”：在 vest 前就行权，并约定离职时公司按行权价回购未 vest 股份。缺点是提前付现金，公司失败会损失大部分钱；优点是行权价接近普通股公允价、没有即时收益和短期税负，需提交 83(b)，且长期资本利得计时从购买日起算，几年后出售可享长期税率。

I've "pre-exercised" before, with a meaning different from what's depicted here in the article. In the "pre-exercise", I was able to exercise the stock before I'd vested in it, with the understanding, of course, that the company would buy back my unvested shares at the exercise price if I left the company before vesting all the options. The disadvantage, of course, is that you pay for your stock up front, and will lose all or most of the money if the company doesn't pan out. There are several advantages ... Advantage: the price you exercise at is near the fair-market value of the Common Shares you purchase (and haven't yet vested in), so there's no immediate gain and so no immediate short-term gain tax consequences. You need to make sure to file an 83(b) form so you're telling the IRS you're paying your $0 tax up front, rather than monthly as your stock vests. (The disadvantage with the latter is that the difference between what you paid and what your stock is worth as it vests could be huge, and there's no way to liquidate your stock to pay that tax.) (There's also something about AMT in here, I'm kind of fuzzy, but I think consequences can be the same.) Advantage: your long-term capital gains clock starts ticking the day you buy the stock, even though you bought before any of it vested. When, three years down the road, you can liquidate your stock in that acquisition or IPO or secondary-market sale, you already purchased your stock three years ago, and pay only long-term gains. Otherwise, you'd buy the stock and sell on the same day, with the gains considered as short-term-gains/income rather than long-term gains. My personal outcome with pre-exercised stock: worked out OK twice, lost all my pre-exercise once, but overall I came out ahead on taxes even with the loss. YMMV. What the article says is "pre-exercise" is just an "exercise" -- you vested the stock, you have every right to purchase it even though the company's stock isn't yet liquid. The problem, of course, is that you may have a huge gain and no way to pay for taxes on that gain. (Edit: note about AMT, clarification.)
先明确股权策略；追问股权细节可能传递愿意牺牲工资的信号。
文章有信息但缺细节，比如没有区分 ISO 和 NQO，而两者税务处理差别很大。作者一方面让候选人追问股权比例，另一方面又说不要用工资换股权；但一旦你强调股权，就等于发出愿意用工资交换股权的信号，反而进入你想避免的谈判。

There's some valuable information here, but a lot of detail is lacking. For instance, the post does not distinguish between incentive stock options (ISOs) and non-qualified stock options. The tax treatment is quite different. More importantly, technical details aside, I think it's important for a prospective employee to make some strategic decisions about equity up front. The author writes: > If the company seems reluctant to answer these questions, keep pressing and don’t take ‘no’ for an answer. If you’re going to factor in your options into any compensation considerations, you deserve to know what percentage of the company you’re getting, and its value. And in the next paragraph he writes: > I’d be wary of compromising on salary for shares, unless you’re one of the first few employees or founders. It’s often a red flag if the founders are willing to give up a large percentage of their company when they could otherwise afford to pay you. Sometimes you can negotiate a tiered offer, and decide what ratio of salary to equity is right for you. You can't have it both ways. If you focus on equity (by demanding that the company divulge detailed information about its share structure), you are sending the signal that equity is just as important or more important than salary, and thus opening the door to a negotiation that contemplates a trade of equity for salary. Precisely the thing that you want to avoid! Unless equity is expected to be liquid in the near future (i.e. you're at a company expected to go public in the near future), an equity-focused negotiation is more likely to benefit the prospective employer than employee.
409(a) 估值可能导致同日行权出售仍按虚高差价缴税，资本损失不能抵消普通收入。
我曾遇到离职后期权三年内到期、二级市场不佳。我安排同日行权和出售，由买家垫付行权款。虽然售价低于最近 409(a) 估值，税务仍按该估值计算行权价差并作为收入征税；随后低于成本价的出售形成资本损失，两者不能相抵，感觉很荒谬。

Fun situation I found myself in a couple of years back: My options were expiring for a company I had worked for (3 year expiration after I left) and the secondary market was not great. I was able to make a sale well above my strike price but below the most recent 409(a) valuation. I arranged a deal where I exercised and sold the shares in the same day, with the buyer fronting the money to exercise as part of the transaction. In this case despite the fact that I sold the shares on the same day for less than the 409(a) valuation, that valuation is still used to determine taxes owed for exercising. And that spread is taxed as income, whereas the subsequent "loss" on the sale (since the cost basis for the stock was then the 409(a) valuation and I sold lower than that) is a capital loss, and so they do not cancel each other out. Luckily in my case my sale price was just a little below the 409(a) valuation so I didn't get hit too hard but still, it felt absurd.
