I left a company and exercised my NSOs months later just before they were to expire. I did a “cashless” exercise where I essentially sold shares that I exercised back to the company in order to cover the cost of the exercise event. I did the same to cover the cost of taxes that I assume they were required to collect from me at the time. Example. I had 10,000 options to exercise. I exercised them all but used 3000 to cover the cost to buy the shares and 1000 shares to cover the taxes. I’m left with 6000 shares when it is all said and done. The company uses Carta to handle their options. The stock is not publicly traded.
What form should I look for and who will send it? I got the W2 from the company but it did not include any of this income or the taxes I paid. Should I expect a 1099 from Carta? Will it include these amounts? How do I report this in TurboTax?
