Thank you for clarifying. You are a bit wrong, and I'm not a tax accountant, but speaking from experience as someone who has had options that have vested and exercised in startups, and have paid taxes on them. I appreciate you engaging with me and I'm trying to help you.
If you buy an option right now in uber, you will not be taxed until you exercise that option (I'm 99% sure of this -- I don't trade options, but also I think you can buy/sell options contracts themselves, and I don't know the tax implications of that) You will either have a capital gain, or a capital loss. An option is the right to buy/sell a stock at a price. You don't get taxed until the moment you actually buy/sell the asset.
When you are given options in a startup they work the same way, it's just a contract, you will have no tax implications until you actually receive something of value, by exercising the right to purchase the stock.
> So a very low strike price seems to force employees to pay taxes when they vest.
People don't pay taxes when the options vest, because that's just a part of a contract. People pay taxes when they exercise the right to purchase those options which converts them into shares. If your equity is worth 100,000 FMV and your strike price for those options equals 10k and you do nothing, you have no tax. If you execute that contract, you pay 10k, get 100k worth of stock, and have a 90k gain. That's what you are taxed on.
This is what forces people in startups to pay taxes and the dangerous part is you might pay taxes and never get a chance to sell the stock.
I'll share two examples:
- I've exercised options where the strike price == FMV, and paid no tax. But the operative word you keep mixing up is vesting and exercising.
- I also currently have options that are vesting in 10 days, and I will not pay tax until I exercise them.
RSUs are different, because they are literally actually stock, it's not a contract to buy stock, so you are given an asset, and you are taxed appropriately for it as you had a capital gain. (The same as the second half of an options contract, you get stock, you are taxed on the value that you get)
Does this help to clarify?
