Wyoming No Income Tax 2026: Full State Tax Breakdown

Wyoming is one of nine US states with no personal income tax — and unlike Nevada (where the prohibition is enshrined in the state constitution), Wyoming simply never enacted one. There is no law forbidding it, no constitutional amendment needed. The legislature just never passed an income tax. That makes Wyoming unusual: its no-tax status is a political choice rather than a legal barrier, but it has remained stable for over a century.

What makes Wyoming's tax situation distinctive is the Mineral Trust Fund. Royalties from oil, gas, coal, and trona mining flow into a fund that now exceeds $9 billion. The fund's earnings subsidise state government, reducing the need for broad-based taxes on residents. Wyoming has no income tax, no estate tax, no capital gains tax, and no corporate income tax — making it one of the most tax-friendly states in the country by almost any measure. The tradeoff: Wyoming has one of the smallest state governments per capita in the US, with correspondingly limited public services compared to higher-tax states.

Wyoming vs High-Income-Tax States: What You Actually Save

The income tax saving from Wyoming residency depends entirely on what state you are comparing against. Wyoming has no state income tax at all — $0 regardless of income level. Here is what that means at common income levels:

• $75,000 income: Save $3,450 vs Colorado (4.40%), $4,620 vs Oregon (8.75%), $5,170 vs California (9.30%)
• $100,000 income: Save $4,600 vs Colorado, $6,600 vs Oregon top bracket, $6,600 vs California effective rate
• $150,000 income: Save $6,900 vs Colorado, $9,800+ vs Oregon (9.9% top bracket), $13,700 vs California (10.3% + surcharges)
• $500,000 income: Save $22,000 vs Colorado, $49,500 vs Oregon, $55,000+ vs California (13.3% top bracket)

Unlike Nevada or Texas — which are large states with major metros — Wyoming is a low-population state with limited urban amenities. The tax saving is real, but the lifestyle tradeoff is significant for those accustomed to large-city infrastructure.

What Taxes Wyoming Residents Actually Pay

Sales Tax: Wyoming levies a 4% state sales tax. Counties add between 1% and 2% local option tax, giving a statewide average of approximately 5.36% combined. Teton County (Jackson Hole) charges 6% combined — the highest in the state but still below the national average of ~7.1%. Groceries are exempt from state sales tax but counties may apply local tax on food.

Property Tax: Wyoming property tax is assessed at 9.5% of market value for residential property, then the mill levy (set by local governments) is applied to that assessed value. Effective rates average approximately 0.57% of market value — among the lowest in the Mountain West and well below the national median of ~1.1%. On a $400,000 home, expect roughly $2,280/year in property tax. Teton County (Jackson Hole) is significantly higher due to sky-high property values, though effective rates remain moderate.

Federal Taxes: Wyoming residents pay the same federal income tax as all Americans — 10% to 37% marginal brackets with standard deductions. Because there is no state income tax deduction to claim, the SALT deduction cap ($10,000) primarily affects property tax deductibility for Wyoming residents who itemise.

Wyoming for Trusts, LLCs, and Asset Protection

Wyoming has quietly become one of the premier trust and LLC domicile states in the US — second only to South Dakota for dynasty trusts, and arguably equal or superior for LLCs and asset protection.

Wyoming LLCs: Wyoming invented the LLC in 1977 (it was the first US state to create the LLC structure). Wyoming LLCs have strong charging order protections — creditors of an LLC member cannot seize the member's interest, only attach a charging order against distributions. Wyoming also allows single-member LLCs with the same protections and permits perpetual duration with no mandatory dissolution requirements.

Dynasty Trusts: Wyoming abolished the Rule Against Perpetuities (RAP) in 1995. Wyoming trusts can hold assets indefinitely across generations with no forced termination — a 'dynasty trust' for multi-generational wealth preservation. There is no state income tax on trust income accumulated in a Wyoming trust for out-of-state beneficiaries, making Wyoming competitive with South Dakota and Nevada for trust domicile decisions.

Domestic Asset Protection Trusts (DAPTs): Wyoming enacted DAPT legislation allowing self-settled spendthrift trusts — you can contribute assets to a trust that benefits you and potentially protect them from future creditors after a two-year seasoning period. Wyoming's DAPT statute is considered strong, though South Dakota and Nevada are sometimes preferred for their longer track records.

Wyoming for Retirees: Pension, Social Security, and Investment Income

Wyoming is an exceptionally tax-friendly retirement destination. With no income tax, retirees pay $0 state tax on:

• Social Security benefits (all exempt at state level)
• 401(k), IRA, and pension distributions
• Investment income — dividends, interest, capital gains
• Part-time income or consulting revenue

A retiree drawing $80,000/year from a pension plus Social Security would pay no Wyoming state income tax — saving $3,500/year vs Colorado, $6,700/year vs Oregon, and $5,300/year vs Montana. Combined with Wyoming's low property taxes and moderate sales tax (below national average), retirees frequently rank Wyoming among the top five most tax-efficient states.

The main considerations for retirees: Wyoming has a smaller healthcare infrastructure than larger states, severe winter weather across most of the state (Cheyenne, Casper), and limited public transportation. Jackson Hole (Teton County) offers more amenities but is one of the most expensive real estate markets in the country.
