What Wyoming residents actually pay
Wyoming 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 state income tax.
Traditional 401(k) in Wyoming
A pre-tax 401(k) contribution reduces federal taxable income today but not state (there's no state income tax in Wyoming). At retirement, withdrawals are federal-taxed only if you still live here. If you move to a high-tax state before drawing down, you pay that state's rate on every dollar.
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 Wyoming, 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.
Frequently asked
- Does Wyoming tax RSU income the same as wages?
- Wyoming 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 Wyoming?
- Wyoming 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 Wyoming 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 Wyoming move, expect the old state to tax the portion of each tranche attributable to workdays earned there. Wyoming taxes the remainder.
- Can I reduce Wyoming taxes by timing my RSU sales?
- Wyoming has no state income tax, so sale timing affects only your federal bill. NIIT and federal capital-gains brackets are still in play.
