Wyoming Income Tax Calculator 2026

Wyoming has no individual or corporate income tax

Wyoming taxes neither personal income nor corporate income. Residents file no state income tax return, so the federal Form 1040 (due April 15, 2027 for 2026) is your full income tax obligation, whether your income comes from wages, a business, investments or retirement.

The state relies on sales tax (4% state rate, 5.39% average combined), property tax and severance taxes on minerals. Food bought for home consumption is exempt from state sales tax.

2026 federal income tax for Wyoming residents

Wages only, standard deduction:

Retirees in Wyoming

Pensions, IRA and 401(k) withdrawals, and Social Security are all untaxed by Wyoming, so a retiree’s only income tax question is how much of their benefits the IRS taxes. That depends on “combined income” (AGI plus nontaxable interest plus half of benefits); IRS Publication 915 has the worksheet. A retiree living on Social Security alone usually owes nothing.

Federal relief for seniors: filers 65 or older can claim an extra senior deduction of up to $6,000 each, phasing out above $75,000 ($150,000 joint).

Itemizers: deduct sales and property tax

Wyoming residents who itemize can deduct state and local general sales tax instead of income tax, plus property tax, up to a combined $40,400 for 2026. With Wyoming’s relatively low sales tax, the IRS optional tables may give a small figure, but sales tax paid on a vehicle or other major purchase can be added.

Business owners and the self-employed

With no corporate or personal income tax, profit from a Wyoming sole proprietorship, partnership, LLC or S corporation is taxed only on the federal return. For an owner who works in the business, the biggest federal cost is often self-employment tax rather than income tax.

Example: a single Wyoming consultant with $90,000 of net profit owes about $12,717 of self-employment tax and $9,571 of federal income tax for 2026, after the standard deduction and the deduction for half of the self-employment tax but before any qualified business income deduction, which would lower the income tax further. That is $22,288 in total, or 24.8% of profit. A flat 5% state tax on the same profit would add $4,500; in Wyoming it adds nothing. Because nothing is withheld, the federal amount has to be paid through quarterly estimated payments (see IRS Topic 306 for the penalty rules).

Moving to Wyoming or earning income elsewhere

If you move to Wyoming mid-year, file a part-year return in your former state for income earned while you lived there. Wyoming residents who earn wages in a state with an income tax, such as working a contract in Colorado, Idaho or Utah, generally file a nonresident return in that state. Wyoming has no tax to credit against it, so that tax is a real cost.
