Sell + invest
| Bargain element (sale − strike) | $20,000 |
| Federal | |
| State | |
| Medicare | −$290 |
| Additional Medicare | −$180 |
| Market gain over 1 yr at 10.0% | $1,141 |
| LTCG on diversified gain (fed + state + NIIT) | −$321 |
| Net at year 1 | $12,233 |
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
Best payout| Sale proceeds (year 1) | |
| LTCG tax (federal + state + NIIT) | −$14,385 |
| Net at year 1 | $48,218 |
Sold 4,185 shares at exercise to cover strike + tax; 815 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.

Software delivery.
Equity grants at Harness typically include incentive stock options (ISOs) and non-qualified stock options (NSOs).
Jyoti Bansal, who previously founded and sold AppDynamics to Cisco for $3.7 billion, launched Harness in 2017 to replace fragile, script-heavy CI/CD pipelines with an opinionated software delivery platform that automates deployments, rollbacks, feature flags, cloud cost management, and security testing in a single developer console. In December 2025 Harness raised a $240 million Series E led by Goldman Sachs at a $5.5 billion valuation, bringing total funding to roughly $614 million across 14 rounds.

Harness NSO exercise creates ordinary income on the bargain element (federal, state, and FICA) at the price on the day you exercise. The calculator works at any valuation, so you can model your exercise cost at the current 409A FMV, an expected IPO price, or post-IPO scenarios.
Example: at Harness's last reported price of $14, exercising 5,000 NSOs with a $4.2 strike creates a $49,000 bargain element, taxed as ordinary income on the day you exercise. Combined federal + state + FICA on that bargain typically lands between $13,230 and $22,050 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.

Harness equity questions
- How is a Harness 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 Harness grant and compares selling the shares now against holding past the one-year mark for long-term capital-gains treatment.
- Does Harness grant ISOs, NSOs, or RSUs?
- Equity compensation at Harness typically takes the form of incentive stock options (ISOs) and non-qualified stock options (NSOs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise.
- Are Harness shares eligible for QSBS?
- They might be. Qualified small business stock (QSBS) under Internal Revenue Code Section 1202 can exclude federal tax on much of the gain when shares were acquired at original issuance from a C-corporation while its gross assets were under $50 million, and held at least five years. Whether your Harness shares qualify turns on when you acquired them and the company's asset size at that time.
