Wyoming Income Tax Calculator

How to Use This Wyoming Income Tax Calculator

This Wyoming income tax calculator estimates your annual federal tax liability for 2025 and 2026. Enter your gross wages, filing status, and any pre-tax deductions or credits above. Because Wyoming levies no state income tax, the state line in your results will always show $0 — your liability consists entirely of federal income tax and FICA (Social Security and Medicare).

This tool focuses on your annual tax picture — total taxes owed for the year, effective rates, and net income. For a per-paycheck breakdown, use the Wyoming paycheck calculator.

Why Wyoming Has No State Income Tax

Wyoming is one of nine US states with no individual income tax on wages. Unlike Texas, which has a constitutional barrier requiring voter approval to impose an income tax, Wyoming has simply never enacted one since statehood in 1890. The other no-income-tax states are Alaska, Florida, Nevada, New Hampshire (investment income only), South Dakota, Tennessee, Texas, and Washington.

Instead of an income tax, Wyoming funds state and local government through:

• Mineral severance taxes— Wyoming is one of the largest coal, natural gas, and oil producers in the United States. Severance taxes on mineral extraction are the state's primary revenue source, effectively subsidizing public services for residents at the expense of resource companies.
• Federal mineral royalties — the federal government shares royalties from energy extraction on federal lands with Wyoming, providing a revenue stream unique to resource-rich Western states.
• State sales tax — 4% on most goods and services, with local counties adding up to 2% (6% maximum combined). Notably lower than most states.
• Property tax — Wyoming has among the lowest effective property tax rates in the nation; residential property is assessed at 9.5% of fair market value.

Federal Income Tax — The Only Income Tax Wyoming Residents Owe

Federal income tax uses a progressive bracket system: each tier of income is taxed at an increasing rate, but only the dollars within each bracket are taxed at that rate. For a single Wyoming filer in 2026:

• 10% on the first $12,400 of taxable income
• 12% on $12,400–$50,400
• 22% on $50,400–$105,700
• 24% on $105,700–$201,775
• 32% on $201,775–$256,225
• 35% on $256,225–$640,600
• 37% above $640,600

Taxable income is gross income minus the standard deduction ($16,100 for single filers in 2026) or your itemized deductions if those are higher. Your marginal rate is the top bracket you reach; your effective rate is always lower because lower-tier income is taxed at lower rates.

FICA Taxes — Social Security and Medicare

FICA taxes apply to every Wyoming paycheck regardless of state of residence. They are federal taxes, not state taxes.

• Social Security: 6.2% on wages up to $176,100 (2025) or $184,500 (2026). No further withholding once you hit the wage base.
• Medicare: 1.45% on all wages with no cap.
• Additional Medicare: 0.9% on wages above $200,000 (single) or $250,000 (married jointly) — employee only, no employer match.

Self-employed Wyoming residents pay the full 15.3% self-employment tax (both halves) on net earnings, but can deduct the employer-equivalent half from gross income to reduce federal income tax.

Wyoming vs. Neighboring States — Annual Tax Savings

Living in Wyoming means keeping significantly more of your annual income compared to neighboring states with income taxes. A few annual examples for a single filer in 2026:

• vs. Colorado ($80,000): Colorado charges a flat 4.4% state income tax — about $3,520 on $80,000 taxable income. A Wyoming resident keeps that full amount. Compare using the generic paycheck calculator.
• vs. Montana ($80,000): Montana uses a 5.9% flat tax, meaning a Montana resident at $80,000 pays roughly $4,720 in state income tax. The Wyoming advantage is nearly $5,000 per year at this income level.
• vs. Utah ($80,000): Utah charges a flat 4.55% — about $3,640 on $80,000 taxable income. Wyoming workers keep the entire difference.
• vs. Idaho ($80,000):Idaho uses progressive brackets up to 5.8%, resulting in roughly $4,150 in state income tax on $80,000. Wyoming's zero-income-tax status saves this amount in full.

How to Reduce Your Wyoming Annual Tax Liability

Because Wyoming has no state income tax, every pre-tax deduction saves only federal tax — but federal rates reach 22–37%, so the savings are still meaningful.

• Maximize traditional 401(k) contributions — the 2026 limit is $23,500 ($31,000 if age 50+). At the 22% bracket, maxing out a 401(k) reduces federal income tax by $5,170/year.
• Contribute to an HSA — if enrolled in a high-deductible health plan, the 2026 limit is $4,300 (self-only) or $8,550 (family). HSA contributions are pre-tax, growth is tax-free, and qualified withdrawals are tax-free.
• Use a Dependent Care FSA — up to $5,000 per household in pre-tax dollars for childcare or elder care expenses.
• Harvest capital losses — realized investment losses offset capital gains dollar-for-dollar, and up to $3,000 per year can offset ordinary income.
• Adjust your W-4 — if you regularly receive a large federal refund, you are giving the government an interest-free loan. Update your W-4 to reduce withholding and receive more in each paycheck throughout the year.
