RSU tax in New Mexico
A $60,000 vest costs $3,240 in New Mexico tax on top of the federal bill. And the federal share withheld is $2,970 short.
What a $60,000 vest actually costs in New Mexico
A single filer already earning $180,000 in salary. The vest stacks on top of that, so it fills the highest brackets rather than starting at the bottom:
| Withheld by your employer at 22.0% | $13,200 |
| Federal tax the vest actually costs | $16,170 |
| Federal shortfall, owed in April | $2,970 |
| New Mexico income tax on the vest | $3,240 |
| Total still to find | $6,210 |
The withholding rate is flat, 22.0% below $1 million of supplemental pay. And takes no account of your salary. That is why the gap grows the more you earn.
The gap widens with salary
| Salary | Withheld | Actually owed | Shortfall | New Mexico tax |
|---|---|---|---|---|
| $90,000 | $13,200 | $13,764 | $564 | $2,940 |
| $160,000 | $13,200 | $14,570 | $1,370 | $3,040 |
| $260,000 | $13,200 | $20,630 | $7,430 | $3,540 |
How New Mexico treats a vest
New Mexico taxes a vest as ordinary income like any other wages, adding $3,240 on top of the federal bill for $60,000 of vesting stock.
If you moved during the vesting period, the income is split between the states you worked in across it: Days worked in each state / total days in vesting period x RSU income = each state's allocation That is worked out day by day, not by where you lived on the vesting date.
New Mexico specifics that change the number
New Mexico is a community property state. In community property states, income earned during marriage is generally owned equally by both spouses. This affects QJV eligibility, MFS filing strategies, and retirement account contribution rules.
New Mexico is one of the twelve states that still taxes Social Security benefits, which matters if you are drawing benefits alongside a vest.

RSU questions in New Mexico
Should I sell at vest?
Selling immediately raises the cash for the $6,210 you still owe and leaves no capital gain, because the sale price equals the price you were already taxed on. Holding turns it into an investment decision, any further gain is a capital gain, and any fall is a loss you take on shares you were already taxed on at the higher value.
I moved to New Mexico mid-vest, who taxes it?
Both states, split by workdays. The income is allocated across the vesting period, not assigned to wherever you happened to live on the vesting date. The state you left can still claim its share, and California, New York and Massachusetts pursue it hardest.
