Explaining Startup Equity to Employees: What to Share
Employees can only value equity they understand. Share share counts, fully diluted totals, strike price, vesting, exit windows, and tax basics.
Explaining Startup Equity to Employees: What to Share
1 / 7
The core idea
- Equity only works as pay if the person receiving it can estimate what it might be worth and what it could cost them.
- Good communication gives employees the inputs—share counts, prices, and terms—rather than a single projected dollar figure.
- Employees who understand their grants make better exercise and tax decisions and are less likely to feel misled later.

What numbers belong in an offer?
- The number of shares or units granted and the company's fully diluted share count, so ownership can be calculated.
- The strike price for options, the latest 409A fair market value, and the date of that valuation.
- The most recent preferred price investors paid, clearly labeled, since it usually exceeds the common-stock 409A value.
- The vesting schedule, cliff, any acceleration terms, and the post-termination exercise window.
How should grant types and taxes be explained?
- ISOs can receive favorable tax treatment, but only on up to $100,000 of value first exercisable each year; the excess is treated as NSOs.
- NSO exercises create ordinary income on the spread, while ISO exercises can trigger alternative minimum tax even without a sale.
- RSUs are taxed when they settle, which at private companies often depends on an IPO or acquisition.
- Companies can explain mechanics, and it helps to tell employees plainly to confirm their own situation with a tax professional.
Should companies offer early exercise or longer exercise windows?
- Early exercise with an 83(b) election can reduce taxes when the spread is near zero, but employees may pay for stock that becomes worthless.
- Unvested early-exercised shares are usually subject to a company repurchase right on departure; plan documents set the price and terms.
- ISOs generally must be exercised within three months of leaving to keep ISO status, so longer windows turn them into NSOs after that.
- Longer windows keep already-granted options outstanding, which affects pool management and overhang rather than creating new dilution.
What ongoing updates help employees?
- Share each new 409A value and the fully diluted count after financings, so employees can track their stake.
- Explain dilution and liquidation preferences in plain terms; preferences can leave common holders with little at modest exits.
- Label any exit scenarios as illustrative, not forecasts, and include a case where the equity is worth nothing.
- If a company issues more than $10 million under Rule 701 in 12 months, securities law requires added financial and risk disclosure.
Common mistakes
- Quoting a dollar value based on the preferred price, which overstates what common shares are likely worth.
- Leaving the exit window unexplained until someone resigns and faces an exercise bill with 90 days to decide.
- Treating the 409A value as a market price; it is a tax-compliance appraisal, not a price anyone has agreed to pay.
Key takeaways
- Give employees the inputs—shares, fully diluted count, strike, 409A, and preferred price—rather than a promised outcome.
- Explain ISO, NSO, and RSU tax differences at a high level and point people to professional tax help.
- Disclose exit windows and repurchase rights up front, before they become urgent.
- Pair every upside scenario with a zero-value scenario to keep the picture fair.
