Established Public Company: Liquid Equity and Year-Over-Year Optimization

With liquid public stock, you can execute flexible tax strategies: timing exercises and sales to manage tax brackets, harvesting losses in down years, and diversifying on your schedule. Learn exercise-and-sell tactics, when to hold for long-term gains, and how 10b5-1 plans coordinate with tax planning.

Liquid stock means more options. Unlike private company equity, you can sell public company shares whenever you want (subject to insider trading rules). This liquidity makes tax planning more flexible: you can time sales to manage bracket exposure, harvest losses in down years, and diversify on your own schedule.

Exercise-and-sell strategies for options. With NSOs, many employees exercise and sell immediately to avoid holding risk. With ISOs, the question is whether holding for the qualifying period (one year after exercise, two years after grant) to get long-term capital gains treatment is worth the price risk of holding a concentrated position. A CPA models the breakeven: how much would the stock need to drop before the tax savings from LTCG treatment are wiped out.

Tax-loss harvesting with company stock. If your stock drops below your cost basis (the value at vesting for RSUs, or the exercise price plus spread for options), selling generates a deductible capital loss. You can use up to $3,000 per year of net capital losses against ordinary income, and carry forward the rest. But watch wash sale rules if you're still receiving new grants.

10b5-1 trading plans. If you're an insider (officer, director, or someone with regular access to material nonpublic information), a 10b5-1 plan lets you set up a predetermined selling schedule during an open trading window. The plan then executes automatically, providing an affirmative defense against insider trading claims. These plans have tax implications that your CPA should coordinate with your securities attorney.

The pitfall: Familiarity breeds complacency. When equity comp arrives every quarter like clockwork, people stop thinking about tax optimization. But small decisions compounding over years -- which lots to sell, when to exercise, whether to hold for LTCG -- add up to significant differences in after-tax wealth.
