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

Equity comp at Klaviyo
- 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 Klaviyo (KVYO) 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 Klaviyo (KVYO)'s last close of $13.84, exercising 5,000 NSOs with a $4.15 strike creates a $48,450 bargain element, taxed as ordinary income on the day you exercise. Combined federal + state + FICA on that bargain typically lands between $13,082 and $21,803 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.

Klaviyo equity questions
- How is a Klaviyo 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 Klaviyo grant and compares selling the shares now against holding past the one-year mark for long-term capital-gains treatment.
- Does Klaviyo grant ISOs, NSOs, or RSUs?
- Equity compensation at Klaviyo typically takes the form of incentive stock options (ISOs), non-qualified stock options (NSOs), and restricted stock units (RSUs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise. Restricted stock units are taxed as ordinary income when they vest.
- Do Klaviyo RSUs use double-trigger vesting?
- No. Klaviyo 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.
