ISO exercises and AMT in Nebraska

Nebraska does not run a separate state AMT. Federal AMT still applies on your ISO bargain element; we walk through the interaction.

What Nebraska residents actually pay

Nebraska taxes ordinary income at a top marginal rate of 5.84%. 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.

Federal AMT on the bargain element

Exercising ISOs and holding the shares creates AMT "preference income" equal to the spread between fair market value at exercise and your strike price. That's the bargain element. It doesn't show up on a W-2, and many people discover it only when their CPA calculates AMT in April.

Frequently asked

Does Nebraska tax RSU income the same as wages?
Yes. Nebraska treats RSU ordinary income as wages, taxable at the state's top marginal rate of 5.84%. 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 Nebraska?
Nebraska 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 Nebraska 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 Nebraska move, expect the old state to tax the portion of each tranche attributable to workdays earned there. Nebraska taxes the remainder.
Can I reduce Nebraska taxes by timing my RSU sales?
Nebraska 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.
