How much do I take home in Wyoming? — short answer first

Wyoming is one of nine US states with no personal income tax — and combined with no corporate income tax, Wyoming has the most business-friendly tax structure in the US. The prohibition on personal income tax is constitutional (Article 15 Section 19), requiring a statewide referendum to amend. Wyoming funds itself through mineral severance taxes (oil, gas, coal — historically 60%+ of state revenue), sales tax (4% state + up to 2% local, combined ~5% in Casper), and property tax (~0.61% effective — below US average). For wage earners, Wyoming offers one of the cleanest paychecks in the US. For business owners, Wyoming combines no entity tax + no franchise tax + strong asset protection + low compliance burden — uniquely competitive nationwide.

How Wyoming taxes payroll in 2026

Wyoming has no personal income tax — the prohibition is constitutional (Article 15 Section 19 of the Wyoming Constitution), requiring a statewide referendum to amend. Wyoming has held this position since the state's founding in 1890. Your Wyoming paycheck is reduced only by federal income tax (IRS 2026 brackets), Social Security (6.2% up to ~$181,000), and Medicare (1.45% on all wages + 0.9% additional above $200K single / $250K joint). Wyoming also has NO corporate income tax — a combination found in only Wyoming, South Dakota, and Nevada (with limited exceptions). Combined with strong asset-protection statutes and minimal LLC compliance requirements, Wyoming is one of the most popular states for LLC formation alongside Delaware and Nevada. The Wyoming LLC structure is uniquely favorable for asset protection. There is no state disability insurance, no PFML deduction, no county or city income tax anywhere in Wyoming. The state funds its public services through three primary streams: (1) Mineral severance taxes — oil, gas, coal, and trona mining contribute historically 60%+ of state revenue, though this share has declined as fossil fuel prices have shifted; (2) Sales tax — 4% state + up to 2% local (Casper combined ~5%, Cheyenne combined ~6%, among the lowest US combined rates); (3) Property tax — ~0.61% effective rate statewide, below national average, with substantial production-specific exemptions for ranching and agriculture. Wyoming has consistently ranked as the most tax-friendly US state in multiple national rankings (Tax Foundation, Forbes), driven by the combination of no income tax + low sales tax + low property tax. The trade-off: limited public services in remote areas, sparse infrastructure, and a small population (~580K, second-smallest US state).

Wyoming city callouts

Cheyenne + Casper — Combined sales tax 5-6% (among lowest US); property tax ~0.61% effective; energy + state government anchors; cost of living near US average.
Jackson + Teton County — Combined sales tax 6%; property tax ~0.42% effective (lowest in WY); high-end tourism + dynasty trust planning anchor; explosive home-price growth (highest in WY).

How to use this calculator

Enter your annual gross salary. Pre-tax, what your employer pays before any deductions.
Pick filing status. Single, married filing jointly, married filing separately, or head of household. Drives both federal and Wyoming brackets.
Add 401(k) and HSA contributions (optional). Both lower your federal taxable income; HSA also lowers FICA wages.
Read the verdict. Annual + monthly + bi-weekly take-home, federal + state + local breakdown, and effective tax rate.

Common mistakes

Confusing gross with adjusted gross. The calculator wants your gross salary — what your employer pays before any pre-tax deductions or contributions. If you enter your W-2 Box 1 (already net of 401k), the math will under-count your tax.
Forgetting that 401(k) is still subject to FICA. Traditional 401(k) reduces federal income tax but NOT Social Security + Medicare. Only HSA (through payroll) reduces both.
Ignoring multi-state implications. If you work in Wyoming but live elsewhere (or vice versa), you may owe taxes in both states with a credit between them. This calculator assumes you both live and work in Wyoming.
