If you’re working at (or investing in) a private company, equity compensation can feel both exciting and confusing—especially when you hear terms like double-trigger RSUs or ISOs vs. NSOs. If you’re wondering, “What does this mean for my actual paycheck and tax bill?” you’re not alone.
Below is a plain-English overview of how these plans commonly work. (Tax rules are nuanced, so consider this educational—and a good reason to coordinate with your CPA before you make election or exercise decisions.)
What are RSUs?
Restricted Stock Units (RSUs) are a promise to deliver shares to you in the future once certain conditions are met—most often a time-based vesting schedule.
What makes an RSU “double-trigger”?
In many private companies, RSUs are structured so taxes don’t hit before you can turn shares into cash. A double-trigger RSU typically requires two events (“triggers”) before shares are delivered and taxed:
- Time/service vesting (you stay employed long enough), and
- A liquidity event, such as an IPO or company sale (or sometimes another company-defined event).
This approach is often designed to help employees avoid being taxed on shares they can’t sell.
How are double-trigger RSUs taxed?
In many cases, taxation occurs when the RSUs settle (when shares are actually delivered)—which is typically after both triggers happen.
- The value of the shares at settlement is usually treated as ordinary income (similar to a bonus).
- Payroll taxes may apply, and the company may withhold shares or cash (if available) to cover withholding.
- After settlement, any future change in value is generally taxed as a capital gain or loss when you sell (short-term if held 1 year or less; long-term if held more than 1 year).
What are stock options in a private company?
A stock option gives you the right to buy shares later at a set price (the strike price). The two common types are:
Incentive Stock Options (ISOs)
- Typically no regular income tax at exercise, but the “spread” (difference between fair market value and strike price) may count for AMT (Alternative Minimum Tax).
- If you meet certain holding rules (often: 2 years from grant and 1 year from exercise), the eventual sale may be taxed at long-term capital gains rates.
Nonqualified Stock Options (NSOs)
- When you exercise, the “spread” is typically taxed as ordinary income and may be subject to payroll withholding.
- Any additional gain/loss after exercise is generally capital gain/loss when sold.
A practical planning note
With private-company equity, timing matters—especially around IPO windows, tender offers, and share-sale restrictions. Before acting, it often helps to review:
- Your vesting schedule and plan documents
- Whether you have double-trigger language
- The difference between ISOs and NSOs
- Your cash flow for taxes and potential AMT exposure
