What North Carolina residents actually pay
North Carolina taxes ordinary income at a top marginal rate of 4.25%. 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.

Withholding gap
Federal supplemental-wage withholding on RSU vesting is flat — 22%, rising to 37% once year-to-date supplemental wages exceed $1M. If your actual marginal rate is higher, the shortfall shows up at filing. In North Carolina, layer on 4.25% at the top and model what you'll owe before year-end.
Sourcing when you move
If you earned part of a vesting tranche while in a different state, most high-tax states (California, New York, Massachusetts) use workday allocation between grant and vest. Your payroll will likely withhold only for your current state, so a manual true-up at filing is the rule, not the exception.
Frequently asked
- Does North Carolina tax RSU income the same as wages?
- Yes. North Carolina treats RSU ordinary income as wages, taxable at the state's top marginal rate of 4.25%. 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 North Carolina?
- North Carolina 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 North Carolina 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 North Carolina move, expect the old state to tax the portion of each tranche attributable to workdays earned there. North Carolina taxes the remainder.
- Can I reduce North Carolina taxes by timing my RSU sales?
- North Carolina taxes long-term capital gains at the same rate as ordinary income, so timing alone does not produce a state savings — only federal. Holding for 12 months still halves the federal rate on gains above basis.
