Best payout| Bargain element (sale − strike) | $350,000 |
| Federal | |
| State | |
| Medicare | −$5,075 |
| Additional Medicare | −$3,150 |
| Market gain over 1 yr at 10.0% | $18,573 |
| LTCG on diversified gain (fed + state + NIIT) | −$5,219 |
| 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

Weaviate equity questions
- How is a Weaviate 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 Weaviate grant and compares selling the shares now against holding past the one-year mark for long-term capital-gains treatment.
- Does Weaviate grant ISOs, NSOs, or RSUs?
- Equity compensation at Weaviate 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 Weaviate 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 Weaviate shares qualify turns on when you acquired them and the company's asset size at that time.
