A breakdown of when and how startups should use different equity compensation types — restricted stock awards (RSAs), incentive stock options (ISOs), non-qualified stock options (NSOs), and restricted stock units (RSUs).

Equity compensation is the cornerstone of startup talent strategy, but the landscape of equity instruments has grown increasingly complex. Understanding the differences between stock options, restricted stock awards, and restricted stock units — and knowing when to use each — is critical for companies that want to attract and retain top talent.

The Four Main Equity Instruments

Restricted Stock Awards (RSAs) are typically used in very early-stage companies when the stock price is near zero. Incentive Stock Options (ISOs) offer favorable tax treatment for employees but come with significant limitations and complexity. Non-Qualified Stock Options (NSOs) are more flexible and can be granted to advisors and contractors. Restricted Stock Units (RSUs) have become increasingly popular at later-stage companies because they have value even if the stock price doesn't appreciate above the grant price.

The right equity instrument depends on your company's stage, valuation, and the tax implications for your employees. Early-stage companies typically rely on ISOs for their tax advantages, while later-stage companies often transition to RSUs as their stock price increases and the exercise cost of options becomes prohibitive for employees.

Building Your Equity Strategy

A thoughtful equity compensation strategy considers the full employee lifecycle — from initial grants to refresh grants, promotions, and retention packages. Work with experienced compensation advisors and tax counsel to design a program that aligns employee incentives with company goals while minimizing unintended tax consequences.
