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.

Retirement Income and Wyoming Taxes

Wyoming's lack of a state income tax extends to every form of retirement income — no carve-outs, no thresholds, no age requirements. The Wyoming state tax on each of the following is simply $0:

• Social Security benefits— $0 Wyoming state tax on any Social Security income, regardless of your total income level.
• Pension distributions— $0 Wyoming state tax on government, military, or private employer pensions.
• 401(k), IRA, and annuity distributions— $0 Wyoming state tax on withdrawals from traditional or Roth retirement accounts and annuities.
• Military retirement pay— $0 Wyoming state tax on military pensions and survivor benefit plan payments.
• Investment income— $0 Wyoming state income tax on dividends, interest, or capital gains.

Wyoming retirees are also not required to file a state income tax return. Only the federal Form 1040 applies. Combined with no inheritance tax and no estate tax, Wyoming is consistently ranked among the lowest-tax states for retirees and high-income individuals. Wyoming stands alongside Alaska as one of only two states that fund state government operations primarily from natural resource extraction — mineral severance taxes on coal, natural gas, and oil — effectively offloading much of the tax burden onto resource companies rather than residents.

Wyoming Tax Credits, Deductions, and Filing

Because Wyoming has no state income tax, the entire landscape of state-level tax credits and deductions is irrelevant for Wyoming residents. There is no Wyoming Earned Income Tax Credit (EITC), no Wyoming standard deduction, and no Wyoming itemized deductions — because there is no Wyoming income tax return on which to claim them. Federal credits and deductions apply in full:

• Federal EITC— Wyoming wage earners who meet federal income thresholds are fully eligible for the federal Earned Income Tax Credit. Wyoming offers no state-level EITC match.
• Federal Child Tax Credit— up to $2,000 per qualifying child under age 17, with the refundable Additional Child Tax Credit available to lower-income filers.
• Federal standard deduction— $16,100 for single filers and $32,200 for married filing jointly in 2026. Wyoming residents claim this (or itemized deductions) on their federal return only.
• Retirement contribution deductions— traditional 401(k), IRA, HSA, and SEP-IRA contributions reduce federal taxable income; there is no state benefit to capture because Wyoming levies no income tax.

Filing deadline: Wyoming residents file only the federal Form 1040 by April 15 each year (or the next business day if April 15 falls on a weekend or federal holiday). No Wyoming state income tax return exists. Extensions for the federal return are available through October 15 by filing Form 4868, but any tax owed must still be paid by April 15 to avoid interest and penalties.
