Self-Employment Tax in Wyoming (2026)

Q: What is the self-employment tax rate in Wyoming?

The federal rate is 15.3% - 12.4% for Social Security up to the annual wage base plus 2.9% for Medicare - applied to 92.35% of net profit from self-employment. Wyoming adds nothing, because the state has no individual income tax. High earners also pay 0.9% Additional Medicare Tax.

Q: Does Wyoming have a state self-employment tax?

No. Wyoming imposes no individual income tax and no separate state self-employment tax. The only income-based tax on self-employment earnings is federal. Wyoming does levy sales and use tax and property tax, which are separate obligations from income.

Q: When do I have to pay self-employment tax?

You owe SE tax if your net earnings from self-employment reach $400 for the year. Because nothing is withheld, the IRS expects quarterly estimated payments on Form 1040-ES covering both income tax and SE tax, with the final reconciliation on Schedule SE filed with your Form 1040.

Q: How is self-employment tax calculated?

Take net profit from Schedule C, multiply by 92.35%, then apply 12.4% Social Security up to the annual wage base and 2.9% Medicare on the whole amount. One-half of the resulting SE tax is deductible in figuring adjusted gross income, which reduces income tax but not SE tax.

Q: Does forming a Wyoming LLC reduce self-employment tax?

Not by itself. A single-member LLC is disregarded by default, so its profit remains self-employment income to the owner. Only an S-corporation election changes the analysis, by splitting earnings into a reasonable salary and distributions that are generally not subject to SE tax.

Q: Do I pay self-employment tax on rental income in Wyoming?

Usually not. Rental income from real estate is generally excluded from net earnings from self-employment, so it is not subject to SE tax, although it is still reported for income tax. Substantial services provided to occupants can change that treatment, so check the facts of your arrangement.

Self-employed people in Wyoming pay federal self-employment (SE) tax of 15.3% - 12.4% Social Security up to the annual wage base plus 2.9% Medicare - on net earnings, computed on Schedule SE. Wyoming imposes no state individual income tax, so no state layer is added on top of the federal amount.

Quick Answer

Federal SE tax rate: 15.3% (12.4% Social Security + 2.9% Medicare)
Base: 92.35% of net profit from self-employment
Filing threshold: $400 or more of net earnings from self-employment
Form: Schedule SE, filed with Form 1040
Wyoming income tax: None - Wyoming has no individual income tax
Deduction: One-half of SE tax is deductible in figuring adjusted gross income

What Self-Employment Tax Is

Self-employment tax is the Social Security and Medicare contribution paid by people who work for themselves. An employee splits those contributions with an employer: the worker pays 7.65% and the employer pays a matching 7.65%. A self-employed person is both sides of that relationship and therefore pays the whole 15.3% - 12.4% for Social Security and 2.9% for Medicare.

SE tax is entirely separate from income tax. It is not a Wyoming tax and not a substitute for federal income tax; a profitable sole proprietor or single-member LLC owner in Cheyenne generally owes both on the same dollars of profit. Understanding that the two run in parallel is the single most useful thing a new Wyoming business owner can learn about their tax bill. See the national self-employment tax guide for the full mechanics.

Who Pays It in Wyoming

You owe SE tax if your net earnings from self-employment are $400 or more for the year. That threshold applies to sole proprietors, independent contractors, freelancers, gig workers, general partners in a partnership, and members of an LLC treated as a partnership. It also applies to the owner of a single-member LLC that the IRS disregards, because the profit is treated as the owner's self-employment income.

Forming a Wyoming LLC does not by itself change this. A disregarded single-member LLC's profit is still self-employment income to its owner, reported on Schedule C and carried to Schedule SE. The liability shield an LLC provides is a legal benefit, not a tax one - see what an LLC is and LLC vs sole proprietorship.

Some income is outside the SE tax base. Wages already subject to FICA withholding, most rental income from real estate, interest, dividends, and capital gains are generally not self-employment income. If you have both a W-2 job and a side business, the wages you already paid Social Security tax on count against the annual wage base, so the Social Security portion of your SE tax can be reduced or eliminated.

How the Tax Is Calculated

The calculation runs in a fixed order:

Start with net profit from the business - gross receipts minus deductible business expenses, from Schedule C.
Multiply by 92.35%. This adjustment exists because an employer's share of payroll tax would have been deductible, so the law approximates that treatment.
Apply 12.4% for Social Security to that amount, but only up to the annual Social Security wage base, which is indexed each year and published by the Social Security Administration.
Apply 2.9% for Medicare to the entire amount - Medicare has no cap.
Add 0.9% Additional Medicare Tax on combined wages and self-employment income above $200,000 for single filers or $250,000 for married filing jointly.

Then take the offsetting deduction: one-half of the SE tax you computed is deductible in arriving at adjusted gross income. It is an adjustment to income, not an itemized deduction, so you get it whether or not you itemize. It reduces income tax only - it does not reduce the SE tax itself. Run your own numbers with the self-employment tax calculator.

Reporting and Paying

SE tax is reported on Schedule SE, filed with your Form 1040, with the business profit itself reported on Schedule C. Because nothing is withheld from a self-employed person's income, the IRS expects payment during the year through quarterly estimated tax payments using Form 1040-ES. Estimated payments cover both income tax and SE tax in a single amount.

The usual estimated-payment due dates fall in April, June, September, and the following January. Underpaying can trigger a penalty even if you pay in full by the April filing deadline, so most Wyoming self-employed people set aside a fixed percentage of every payment received. A common rule of thumb is to reserve enough for 15.3% SE tax plus your marginal federal income tax rate - since Wyoming adds no state income tax, that reserve does not need a state component.

Wyoming Has No State Income Tax

Wyoming is one of a small group of states with no individual income tax. For a self-employed person that means the SE tax and federal income tax are the entire income-based burden - there is no Wyoming return on which to report business profit, and no state estimated payments to make. The Wyoming Department of Revenue confirms that the state does not levy a personal income tax.

That does not make Wyoming tax-free. The state funds itself substantially through sales and use tax and severance taxes, so a Wyoming business that sells taxable goods or services registers with the Department of Revenue, collects sales tax, and remits it. Property tax applies to business property. And local licensing can still apply - see business licenses in Wyoming and the national business license overview.

Can an S-Corp Election Reduce SE Tax?

Sometimes. If an LLC elects S-corporation treatment on Form 2553, the owner becomes an employee of the company and must be paid a reasonable salary, which is subject to payroll tax. Profit distributed beyond that salary is generally not subject to self-employment tax. For a consistently profitable business, that split can produce real savings.

The election is not free. It brings payroll processing, quarterly employment tax returns, a separate Form 1120-S, and additional accounting cost, and the "reasonable salary" standard is enforced - setting an artificially low salary invites IRS adjustment. Most advisers treat the election as worth evaluating only once profit is comfortably above the cost of compliance.

Legitimate Ways to Lower the Bill

Because SE tax is computed on net profit, the most reliable lever is claiming every ordinary and necessary business expense you actually incurred: mileage, home-office space that qualifies, equipment, software, professional fees, and business insurance. Each dollar of legitimate expense reduces both income tax and SE tax. Self-employed retirement plans and the self-employed health insurance deduction reduce income tax, though they generally do not reduce SE tax. Keep contemporaneous records - a deduction you cannot substantiate is a deduction you will lose. See how to get an EIN if you need a business tax ID and the glossary for terminology.
