Pre-IPO assumption: Expected sale price assumes a liquid market at year N. In reality, pre-IPO shares clear via tender offers (priced at a discount to the 409A or last preferred round, on the company's calendar) or at IPO (subject to lockups). Use the haircut to reflect that uncertainty.

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.

Impulse Space 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 Impulse Space's last reported price of $66.15, exercising 5,000 NSOs with a $19.85 strike creates a $231,500 bargain element, taxed as ordinary income on the day you exercise. Combined federal + state + FICA on that bargain typically lands between $62,505 and $104,175 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.

Impulse Space equity questions

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