Does New Hampshire tax RSU income the same as wages?

New Hampshire has no state income tax on wages, so RSU ordinary income is federal-only. Note that Washington residents still owe the 7% state long-term capital gains tax on sales above the threshold, and other states may claw back some income if your grant pre-dated your move.

What happens if I exercise ISOs while living in New Hampshire?

New Hampshire 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 New Hampshire 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 New Hampshire move, expect the old state to tax the portion of each tranche attributable to workdays earned there. New Hampshire taxes the remainder.

Can I reduce New Hampshire taxes by timing my RSU sales?

New Hampshire has no state income tax, so sale timing affects only your federal bill. NIIT and federal capital-gains brackets are still in play.

RSU vesting schedules in New Hampshire: cadence, withholding, and annual tax cycle

What New Hampshire residents actually pay

New Hampshire has no state income tax on wages. That removes a layer — but federal AMT, federal capital gains, and the 3.8% Net Investment Income Tax still apply, and a prior state may still have a claim.

No wage-income tax; interest & dividends tax phasing out.

The vest-day mechanics

On each vest date, shares settle at the closing price and the full value adds to W-2 wages. Your employer runs federal supplemental withholding at 22% (37% above $1M YTD supplemental) with no state withholding, since New Hampshire does not tax wages, plus Medicare and Social Security up to the wage base.

Quarterly cadence

A typical four-year, quarterly-cliff RSU grant produces 16 vesting events. Each one is a supplemental-withholding event at the same statutory rates, which means your under-withholding gap compounds across the year if your marginal bracket is above 22%. Model it per tranche, not per year.

Three scheduled planning windows

Three times a year the math is worth re-running: after the Q1 vest (when you can see YTD withholding trajectory), before the Q3 vest (when you set up Q4 estimates or adjust W-4), and in December (final true-up plus the decision to hold or sell the year's accumulated shares).
