Oh boy, stock options! I’ve had to do a lot of research about those for work, as we have a lot of clients who get stock options or other equity awards of various types, and we have to figure out how to report them, or even before that, advise on the tax consequences of selling them if they’re smarter than the average client and think to ask first.
First, there are the normal well-trod stock options. But wait! There are two kinds! Qualified and non-qualified. This is with respect to a certain tax advantage I’ll get to later. With stock options there are 3 ways that you make money: First, the discount of the strike price to the market price at the time the option is granted. This is always ordinary income - the company is basically giving you something for “free” in exchange for your labor. Second, the change in value of the stock between the time you are granted the option. This is capital gain if the option is qualified and you meet the holding period requirements, and not realized until you sell the stock. For non-qualified options this is ordinary income and is realized at the time the option is exercised, even if you don’t sell the stock after exercise.*** Third, the change in value of the stock between when you exercise it and when you sell it. This is always capital gain.
***(However, in the case of qualified options, the income that you would recognize if they were non-qualified must be taken into account for the Alternative Minimum Tax, giving you a potentially massive difference in your AMT tax liability. You might end up owing more AMT then than the stock is worth by the time the lockup period ends if you’re really unlucky. You technically get to take a credit for excess AMT paid in later years when your AMT is less, but it can be very slow to reverse if you don’t have a large gain when you sell the stock and thus have much lower AMT due that year compared to regular tax due to your higher AMT basis in the stock. And because you pay AMT at ordinary income rates, but get the credit back when you’re being taxed on capital gain, you don’t get it all back just when you sell, so for large enough purchases you could be stuck with a large AMT bill that will take forever to reverse.)
But there is also a 83(b) election, which allows you to pay taxes on the value of the options when they are granted instead of when they vest. I have only seen this used in cases where the time value of the options cannot be determined because there is no market for the stock, and the intrinsic value of them is zero, thus you get taxed on zero dollars of income. This is also the case if you are given a profits interest in an LLC/partnership; so long as you aren’t given equity capital but only a profits interest, the IRS says that since you’ll be taxed on the profits when you receive them through the LLC, and you don’t have the ability to get capital out until you accrue profits that are taxed, you don’t need to pay tax right away, and thus don’t pay anything. In these cases it does mean that you’ll pay a lot in capital gains tax if the stock takes off, but you don’t recognize any ordinary income. Since this is mainly only done in the startup phase before other investors come in, it’s done mainly with the first few starting employees as well as the founders. But it does mean those people can get a huge payday from the equity award and have no ordinary income.
Then there are RSUs - restricted stock units. These are grants of stock you don’t have to pay for that you can’t sell for a while. You recognize ordinary income equal to the fair market value of the stock when the RSUs vest, even if you don’t sell them. This usually means that you end up with far less in stock because you need some automatically sold to cover the payroll taxes and federal (and state) withholding.
There’s also Employee Stock Purchase Programs (ESPP) which are kinda like equity awards, but are simply the ability to buy company stock at a discount, as opposed to being given it (RSUs) or being given the option of waiting to buy when you know you’ll pay much less than it’s worth. You have to recognize ordinary income equal to the discount you’re given.
