Paycheck taxes in Wyoming

Wyoming's budget is dug out of the ground rather than withheld from paychecks. The total severance tax on crude oil, lease condensate, and natural gas is 6% under W.S. 39-14-204, while coal is split by extraction method — 6% for surface-mined coal and 3.75% for underground coal under W.S. 39-14-104. Part of that take is not the legislature's to spend: one and one-half percentage points of the rate is imposed directly by Article 15, Section 19 of the Wyoming constitution, and that portion is deposited into the permanent Wyoming mineral trust fund rather than the general severance tax distribution account. It is an unusual arrangement — a constitutionally mandated savings account fed by mineral extraction, standing in for the income tax the state has no need to levy.

Bonuses and supplemental wages in Wyoming

Wyoming has no state income tax, so a bonus carries no state supplemental withholding at all — whichever method your employer uses, the state takes nothing. Only federal supplemental withholding applies, which is a flat 22% on supplemental wages up to $1 million.

For the federal half, which this site does model, compare what withholding takes from a bonus against what you actually owe — the 22% flat rate is withholding, not a tax bill, and the difference comes back at filing.

Wyoming vs. its neighbors

Wyoming levies no state income tax, so any gap above is state income tax paid by the other states — federal income tax and FICA are identical everywhere. Single filer, $100,000 of wages, no 401(k) or other pre-tax deductions, 2025 state tables. Local income taxes (city and county) are not included. Run your own salary through the calculator above, or on any state's page.

Neighbours are only part of the picture. The study behind these figures ranks what a $100,000 salary takes home in all 50 states, with Wyoming's row in place — the entire spread between best and worst is state income tax, since federal tax and FICA are identical everywhere.

A worked example at Wyoming's median income

That is an effective all-in tax rate of 18.4% at the median — your own number depends on filing status, 401(k), and benefits. Enter your salary above for the exact figure.
