RSU tax in Wyoming
Wyoming takes nothing from a vest, but your employer still under-withholds the federal share, $2,970 of it on the example below.
What a $60,000 vest actually costs in Wyoming
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 |
| Wyoming income tax on the vest | none |
| Total still to find | $2,970 |
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 | Wyoming tax |
|---|---|---|---|---|
| $90,000 | $13,200 | $13,764 | $564 | , |
| $160,000 | $13,200 | $14,570 | $1,370 | , |
| $260,000 | $13,200 | $20,630 | $7,430 | , |
How Wyoming treats a vest
Wyoming has no personal income tax, so a vest is a federal-only event here, $16,170 of federal tax on $60,000 of vesting stock, and nothing to the state.

RSU questions in Wyoming
Should I sell at vest?
Selling immediately raises the cash for the $2,970 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 Wyoming 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.
