Taxation of Stock Options Cheat Sheet

Overview

Stock options are a form of equity compensation that can provide financial benefits but come with tax implications. The tax treatment depends on the type of stock option and how it is exercised or sold.

Types of Stock Options & Tax Treatment

*1. Incentive Stock Options (ISOs)*

• No taxable event at grant or exercise.
• Alternative Minimum Tax (AMT) may apply if exercised and held.
• Gains taxed at long-term capital gains rates if held 1 year after exercise & 2 years after grant.
• Disqualifying disposition (selling early) results in ordinary income taxation.

*2. Non-Qualified Stock Options (NSOs)*

• No taxable event at grant.
• Upon exercise, the difference between the strike price and fair market value is taxed as ordinary income.
• Any subsequent gains taxed as capital gains based on holding period.

*3. Employee Stock Purchase Plans (ESPPs)*

• Discounted stock purchases may be taxed as ordinary income.
• Holding period determines whether gains are taxed at capital gains rates.

Tax Planning Strategies

1. Hold ISOs for Long-Term Gains: Avoid early sales to qualify for lower tax rates.
2. Plan for AMT on ISOs: Monitor AMT triggers when exercising options.
3. Time NSO Exercises Strategically: Avoid pushing income into higher tax brackets.
4. Use ESPPs for Tax-Efficient Investing: Consider holding periods for favorable tax treatment.

Common Pitfalls & How to Avoid Them

• Ignoring AMT on ISOs: Plan for potential tax liabilities.
• Selling Too Soon: Early sales may result in higher ordinary income tax rates.
• Overlooking Payroll Taxes on NSOs: Ensure proper withholding at exercise.
