Sell-to-Cover Strategy: A Guide for Equity Compensation

Sell-to-cover is a strategy where you sell just enough shares to cover the tax obligations associated with equity compensation events, such as RSU vesting or option exercises. This approach allows you to retain the majority of your shares while meeting your tax obligations without using cash from other sources.

How Sell-to-Cover Works

Basic Mechanics: When equity compensation vests or is exercised:

• The company calculates the tax obligation
• Automatically sells the minimum number of shares needed for taxes
• Deposits the tax payment with relevant authorities
• Delivers remaining shares to your account

Example Calculation: Sarah receives 1,000 RSUs vesting today:

• Current stock price: $100 per share
• Total value: $100,000
• Required tax withholding: 35% ($35,000)
• Shares needed to cover taxes: 350 shares ($35,000 ÷ $100)
• Net shares retained: 650 shares
