NSO exercises and state tax in Vermont

NSO spread is ordinary wage income at exercise; Vermont takes 8.75% of that at the top bracket, plus its share of any later capital gain on sale.

What Vermont residents actually pay

Vermont taxes ordinary income at a top marginal rate of 8.75%. RSU settlement value, NSO exercise spread, and ESPP discount income all count as ordinary wages for this purpose and flow through the state's normal brackets.

Ordinary income at exercise

NSO spread (FMV minus strike at exercise, times shares) is ordinary wage income in the year of exercise. Vermont taxes it at up to 8.75%, stacked on your base wages. Federal supplemental withholding applies at 22% (or 37%), just like RSUs.

Cash outlay vs tax

NSO exercise requires cash for the strike price plus tax withholding. Cashless exercise (same-day sell) nets out the cash requirement but converts the full spread to ordinary income in the exercise year. Early exercise with 83(b) is available on pre-vesting NSOs at some companies; it starts the long-term capital gain clock on the full share value going forward.

Interaction with later sales

After exercise, your basis equals strike plus spread (the amount taxed as ordinary). Further price appreciation is capital gain on sale, split long-term vs short-term at the one-year mark. For Vermont residents, this is where the state savings from holding a preferential-treatment state matter most.

Frequently asked

Does Vermont tax RSU income the same as wages?
Yes. Vermont treats RSU ordinary income as wages, taxable at the state's top marginal rate of 8.75%. Supplemental-wage federal withholding (22%, or 37% above $1M YTD) does not adjust for state withholding, so you often owe extra at filing.
What happens if I exercise ISOs while living in Vermont?
Vermont does not run a separate state AMT, so only federal AMT applies. You still need to model the bargain element carefully if you plan a cashless exercise-and-sell.
I moved to Vermont from another state. Who taxes my vesting RSUs?
Most high-tax states (CA, NY, MA) source RSU ordinary income to workdays between grant and vest. If your grant pre-dates your Vermont move, expect the old state to tax the portion of each tranche attributable to workdays earned there. Vermont taxes the remainder.
Can I reduce Vermont taxes by timing my RSU sales?
Vermont gives preferential treatment to long-term capital gains. Holding RSU shares 12+ months past vest can produce both federal and state savings. Weigh concentration risk before using this as a reason to hold.
