Ask The Hammer – How do ISOs work?

Key Takeaways

• Track three key dates for ISO taxation: grant date (when options become available), exercise date (when you convert options to stock), and sale date (when you sell). Failing to meet holding period requirements can convert long-term capital gains rates into ordinary income tax rates, costing up to 20% more in taxes for high earners.
• File an 83(b) election within 30 days of receiving ISOs to convert ordinary income into long-term capital gains treatment, but understand the risk: if the stock price drops, you don't recover the taxes already paid on the higher grant price.
• If you believe your company's stock will decline, exercise and sell immediately to lock in gains, accepting higher taxes on those gains rather than facing larger losses if the stock continues falling.
• If you're a long-term believer in your company, hold the stock through the required two-year and one-year holding periods to qualify for long-term capital gains rates (15%) rather than your ordinary income tax rate, which could be as high as 35%.
• Consult a tax professional to map out your specific holding period requirements based on your grant date and exercise date, as the tax impact varies significantly based on your tax bracket.
