| State | |
| Medicare | −$5,075 |
| Additional Medicare | −$3,150 |
| Market gain over 1 yr at 10.0% | $18,573 |

| Net at year 1 | $199,080 |
Sell every share immediately; invest the after-tax cash at the market return for 1 yr, then liquidate. Diversified — no single-stock concentration risk.
Exercise + hold 1 yr
| Sale proceeds (year 1) | |
| LTCG tax (federal + state + NIIT) | $0 |
| Net at year 1 | $178,297 |
Sold 2,678 shares at exercise to cover strike + tax; 2,322 shares held 1 yr for LTCG.
Social Security + Medicare are payroll taxes (collectively called FICA) — they apply because you're exercising as a current employee.
Both columns are stated in year-1 dollars: sell-now proceeds compound at the market return and pay LTCG on the gain at year 1; any cash paid out of pocket on the hold side carries the same opportunity cost.
Net at year N — by hold period
Estimates only. Excludes AMT (NSOs do not trigger AMT), state-AMT, multi-state moves, and disqualifying-disposition edge cases. Not financial advice.
You calculated one NSO decision. The beta plans NSOs alongside RSUs and ISOs in a single multi-year tax plan.

Jay Chaudhry and K. Kailash founded Zscaler in 2007 to rebuild corporate security as a cloud service rather than a stack of on-premise appliances. The San Jose company routes employee web and application traffic through its Zero Trust Exchange, brokering access per-session instead of trusting the network perimeter. Core products split into ZIA for internet filtering, ZPA for private app access, and ZDX for digital experience monitoring. Shares debuted on NASDAQ in March 2018 at $16, and annual recurring revenue has since crossed $2 billion as enterprises retire legacy VPNs.

Equity comp at Zscaler
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

Use this calculator to estimate your Zscaler (ZS) NSO exercise tax (federal, state, FICA), then compare selling now versus holding through the long-term capital gains threshold. Inputs are yours: grant terms, current price, your income, your state.
Example: at Zscaler (ZS)'s last close of $127.23, exercising 5,000 NSOs with a $38.17 strike creates a $445,300 bargain element, taxed as ordinary income on the day you exercise. Combined federal + state + FICA on that bargain typically lands between $120,231 and $200,385 depending on your bracket and state. The calculator above computes the exact figure for your situation and compares selling now vs. holding through the long-term capital-gains threshold.

Zscaler equity questions
- How is a Zscaler NSO exercise taxed?
- Exercising a non-qualified stock option (NSO) creates ordinary income on the bargain element (the price on the day you exercise minus your strike), subject to federal income tax, state income tax, and FICA. The calculator above computes that tax for your Zscaler grant and compares selling the shares now against holding past the one-year mark for long-term capital-gains treatment.
- Does Zscaler grant ISOs, NSOs, or RSUs?
- Equity compensation at Zscaler typically takes the form of non-qualified stock options (NSOs) and restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Zscaler RSUs use double-trigger vesting?
- No. Zscaler restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
