Does New Mexico tax RSU income the same as wages?

Yes. New Mexico treats RSU ordinary income as wages, taxable at the state's top marginal rate of 5.9%. 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 Mexico?

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

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

New Mexico 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.

401(k) and retirement accounts in New Mexico: state deduction and Roth considerations

What New Mexico residents actually pay

New Mexico taxes ordinary income at a top marginal rate of 5.9%. 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.

Up to 40% of net capital gains deducted from state tax.

Traditional 401(k) in New Mexico

A pre-tax 401(k) contribution reduces both federal and New Mexico taxable income today. At the top bracket, every $1,000 contributed saves 40.9 cents on the dollar (federal 35% + state 5.9%). At retirement, withdrawals are taxed at your then-current bracket.

Roth 401(k) breakeven

Roth 401(k) contributions are taxed at today's rates; withdrawals are tax-free. The Roth choice beats traditional when your retirement bracket is higher than your contribution bracket. For equity earners in high-income years, traditional is usually right during big RSU years and Roth is right during low-income transition years.

Mega-backdoor Roth

After-tax 401(k) contributions above the standard $23,500 limit can be converted to Roth in plans that allow it. For high earners in New Mexico, this is the largest tax-advantaged bucket available after the primary 401(k) and IRA caps. Check whether your plan allows after-tax contributions and in-plan Roth conversions.
