Venture-backed startup companies are big fans of using stock options as a major compensation tool to attract and retain employees. Companies often allow early-exercising of unvested stock because the tax savings is a significant benefit and the invested capital is a demonstration of commitment by the employee. If your company's stock value rises over the years, you can avoid two major tax issues by having exercised early. First is the ever-increasing AMT liability if the Fair Market Value of your stock rises before you finally exercise. Second, is qualifying for long term capital gains based on the exercise date when you actually invested as opposed to the subsequent vesting date. To solve the latter problem, you need to file an 83(b) election within 30 days of your exercise date or else taxes will be computed when the possibility of forfeiture goes away (your vesting date) and the FMV is usually higher at the future vesting dates. A higher FMV results in higher taxes even though you exercised at an earlier date.
Filing an 83(b) with the IRS means that you are bound to consummate your intended stock purchase. The IRS isn't capable of tracking whether you actually leave the company early resulting in a repurchase of the unvested stock, so they simply subject you to the applicable taxation up front based on your expressed intent. However, your cost basis and the fair market value are equal up front so there shouldn't be any taxes due. The exception is if you waited some period of time before executing the early exercise and the fair market value of your company's stock at the time of exercise had risen above your option grant exercise price. Even then, you may or may not be subject to tax depending on several factors such as whether these were qualified ISOs, the implied gain in value, and your level of income. Establishing the purchase date right away also makes the stock eligible for long term capital gains (LTCG) treatment after it is held for at least one year and at least 2 years has passed since the date of the option grant. There is a 20% federal tax savings associated with LTCG but drops to 15% if you are in the highest tax bracket. Although there is no additional tax savings for California because capital gains and ordinary income are taxed at the same rate, there are many other states that do provide an additional tax savings for LTCG.
There is no special form for filing an 83(b) but a sample is provided here. You are cautioned to review this with your tax advisor for compliance with your particular situation and since IRS rules are continually subject to change. Send 2 copies to the IRS along with a self-addressed stamped envelope for them to return a stamped acknowledgment. For exercises that occured on or after January 1, 2015, you no longer need to file a copy of the 83b with your actual tax return. Of course, keep a copy for your records at least until you received the stamped acknowledgment from the IRS.
Exercising stock options early can require a lot of capital and yet the time to liquidity for your company can be quite long. As your shares are vested, you may be tempted to sell some shares to recover your original investment or perhaps fund other financial needs. Be aware that a sale is a taxable even and most likely at high tax rates. A sale also truncates any possibility of future upside on the shares being sold. An alternative solution for partial liquidity is to get an advance from the ESO Fund. This is an attractive solution because no payments are due until a liquidity event is reached on the stock. Furthermore, if the stock becomes worthless, ESO absorbs the loss, not you. For more information, please contact us at the Employee Stock Option Fund.
