Does New Jersey tax RSU income the same as wages?

Yes. New Jersey treats RSU ordinary income as wages, taxable at the state's top marginal rate of 10.75%. 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 New Jersey?

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

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

New Jersey 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.

ESPP taxation in New Jersey: ordinary income, qualifying dispositions, and payroll

What New Jersey residents actually pay

New Jersey taxes ordinary income at a top marginal rate of 10.75%. 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.

Top bracket at $1M; many NYC-area equity earners are NJ residents.

Two taxable events, one plan

An ESPP produces two taxable events. The first is ordinary discount income at purchase (for non-qualified plans or disqualifying dispositions of qualified plans), which New Jersey taxes at up to 10.75%. The second is capital gain or loss on sale, taxed at long- or short-term rates federally and at 10.75% if held as ordinary state income.

Qualifying disposition math

A qualifying disposition requires you hold the shares two years from offering date and one year from purchase. Holding that long converts some of the gain to long-term federal capital gains, which for a high earner in New Jersey still costs 10.75% state plus federal LTCG rates. The trade-off: two years of concentration risk in your employer's stock.

Payroll reporting

Discount income at purchase flows through W-2 Box 1 and is withheld on payroll. The cost basis reported on Form 1099-B usually excludes the W-2 income component, so you must adjust on Form 8949 to avoid double-taxation. This is the most common ESPP filing error.
