How to Start a Contractor Business in Wyoming: No State License, City Licenses in Cheyenne and Casper, and the 4% Nonresident Bond

If you are searching for a wyoming contractor license, start with the most useful fact: the state does not issue one. Wyoming has no state license for general contractors, handymen, roofers, painters, plumbers or HVAC technicians. Contractor licensing happens city by city. The state's role is narrower: the Secretary of State registers your business entity, the Department of Revenue handles sales and use tax, the Department of Workforce Services runs workers' compensation and unemployment insurance, and the state licenses electrical trades.

This guide follows the order most new contractors use: form the entity, insure it, obtain the city licenses for each place you work, set up sales and use tax, and handle the nonresident project bond if you are not a Wyoming resident. Cheyenne and Casper are the main examples, with notes on other cities.

Informational content only. This article is not legal or tax advice. Fees, insurance minimums and rules change, so confirm every figure with the agency named before you file or pay. For complex situations, such as bidding on projects across state lines or hiring subcontractors from out of state, talk with a qualified attorney and a CPA.

What you need before you start

Gather these items before you file anything:

  • A business name that is available on the WyoBiz filing search
  • A Wyoming physical street address for your registered agent (a drop box does not qualify)
  • The filing fee for your entity: $100 for Articles of Organization (LLC) or Articles of Incorporation (corporation)
  • A general liability insurance certificate that meets each city's minimums
  • A Wyoming workers' compensation letter of good standing, which Cheyenne requires before issuing a license
  • A list of every city and unincorporated area where you plan to work
  • A federal employer identification number (EIN) from the IRS
  • A business bank account and a system for keeping materials receipts
  • A surety bond or cash deposit if you are a nonresident contractor, or if you are a Wyoming prime contractor hiring nonresident subcontractors

Step 1: Confirm what the state does and does not license

Wyoming's state-level requirements for a contractor are light. You do not need a state contractor, plumber or HVAC license. Electrical trades are the exception: the state licenses them, and you should check with the Department of Fire Prevention and Electrical Safety before doing electrical work. Everything else runs through the city where you operate. Wyoming also has no general statewide business license. The Secretary of State directs applicants to the city clerk in the city where they will operate to find any business-specific license or permit.

Put that in writing for yourself: your Secretary of State filing does not authorize you to perform construction work anywhere. The city license does.

Step 2: Form your entity with the Secretary of State

Most contractors form a limited liability company (LLC) through the Wyoming Secretary of State's WyoBiz portal at wyobiz.wyo.gov. The steps are:

  • Check the name. Search the business filing search to confirm your name is available and distinguishable. An LLC name must include Limited Liability Company or an accepted abbreviation such as LLC, L.L.C., LC or Ltd. Liability Co. Names beginning with the letter A must be filed on paper rather than online.
  • Reserve the name if needed. A name reservation costs $60 and holds the name for 120 days. It is available on paper only, using the LLC name reservation form.
  • File the Articles of Organization. The filing fee is $100. Online filings are active as soon as they are completed. Paper filings are processed in the order received and can take up to 15 business days. Expedited processing is not available for an online initial formation.
  • Appoint a registered agent. The agent must have a physical Wyoming street address, including any suite number. A PO box may be listed only in addition to a physical address. A commercial registered agent pays a $50 annual registration. Appointing a new agent and office costs $5.
  • Calendar the annual report. The annual report license tax is a $60 minimum, or two-tenths of one mill ($.0002) on the dollar of Wyoming assets, whichever is greater. It is due the first day of your formation's anniversary month. You may file up to 120 days early. If it is not paid within 60 days of the due date, the entity is subject to administrative dissolution.

Wyoming levies no corporate income tax, no personal income tax and no franchise tax. The annual report is the only recurring state entity charge for most small contractors.

If you operate under a name other than your LLC name, you can register a trade name. Registration is optional. It costs $100 for a 10-year term, is filed with the Secretary of State rather than a county clerk, and is submitted by mail with a notarized application.

Step 3: Buy insurance and set up workers' compensation

City insurance minimums vary, so get the requirements for each city before you buy a policy. Several examples:

  • Cheyenne: $1,000,000 / $2,000,000 for Classes A, B and R; $300,000 / $600,000 for Classes C, D and F.
  • Casper: $250,000 per person, $500,000 per incident and $250,000 for property damage.
  • Jackson: $1,000,000 / $2,000,000 for Classes A and B.

Workers' compensation in Wyoming comes from a single state fund administered by the Department of Workforce Services. Coverage is compulsory for construction businesses (NAICS 23). Sole proprietors, partners, officers and LLC members are generally excluded unless they elect coverage, so an owner working alone may not need a policy, but a crew almost always does. Cheyenne asks for a workers' compensation letter of good standing before it issues a license. Unemployment insurance is also a state obligation, so check with the Department of Workforce Services before you hire your first employee.

Step 4: Get the city licenses where you work

Cities and towns issue contractor licenses. Counties do not issue business licenses. They handle land use, building, septic and liquor matters. If a job sits outside city limits, the county may control the permit even though you need no city license.

Cheyenne. Under City Code chapter 5.44 (regulations revised March 10, 2026), you may not perform construction work, provide services or advertise without the required licenses. The city will not issue a license until insurance and the workers' compensation letter are on file. License classes include A (general), B (building), R (residential), C1 (tested trade), C2 (non-tested trade), D1 to D3 (handyman) and F (fire). Every company must register an Individual Qualified Supervisor. For current fees, contact the Cheyenne Compliance Division at (307) 637-6200.

Cheyenne also has an owner exemption. The owner of an owner-occupied one-family dwelling may take a permit and do the work personally. The exemption does not apply within three years of a prior owner permit, so it is not a workaround for repeated flipping or building.

Casper. Call Building Inspection at 307-235-8254 and review the fee table on the City of Casper website (casperwy.gov). Class I (any structure) is $300 for a new license and $150 for renewal. Roofing and demolition are $150 for new and $75 for renewal. Other classes cover: Class IIA for projects up to 12,000 square feet, Class IIB for up to four dwelling units, Class III for single-family remodels up to 25% of the home, and Class IV for limited maintenance. Confirm the fee for each class on the fee table, because the table is the controlling source.

Gillette. The 2026 renewal fees (form dated June 25, 2026) are $500 for Class A, $300 for Class B, $150 for Class R, $75 for Class C, $50 for Class D and $75 for Class F. Gillette requires good standing with the Secretary of State, workers' compensation and unemployment insurance compliance, and an active surety bond.

Laramie. Under LMC 15.24.015 (Ordinance 1875, adopted November 18, 2025), you need a city license and a Qualified Supervisor of Record. Check with the City of Laramie for current fees.

Natrona County and other unincorporated areas. Check with Natrona County directly before working outside city limits.

Septic work. The Department of Environmental Quality permits small wastewater systems only in Campbell County (commercial), Carbon, Niobrara, Platte and Weston counties. Check with DEQ for installer rules before you bid septic work.

Step 5: Register for sales and use tax if you make taxable sales

Wyoming's sales tax license is a separate obligation from your entity filing. You need it if you make taxable sales. Register through the Department of Revenue Excise Tax Division at the sales and use tax registration page. The application carries a $60 non-refundable fee.

The state rate is 4% as of October 2026. County option taxes and resort district taxes are added on top, and there is no city sales tax. County rates change quarterly, so check the current rate chart on the Department of Revenue site before you quote a job or set up your invoicing.

Sales tax in Wyoming applies to goods and to a short list of enumerated services. Repair and alteration of personal property is one taxable service, so a contractor who repairs customers' equipment may need to charge tax on that work. Labor on real property is not taxable, which is covered in Step 6.

Step 6: Understand the contractor tax rule on materials

Under W.S. 39-15-303(b)(i), a contractor who furnishes property under a contract or develops real property is the consumer of the materials it installs. In practice, you pay sales tax on the materials you buy and install, and you charge your customer no tax on those materials. Labor on real property is not taxable.

Wyoming issues no resale certificate. When you buy goods to resell rather than install, you give the seller a signed certificate instead. Keep those certificates with your records, since they are your proof of why you did not pay tax at the counter.

Step 7: Handle the nonresident project bond

A nonresident is someone who was not a bona fide Wyoming resident for one year before bidding, under W.S. 39-15-301. Nonresident contractors face extra steps under W.S. 39-15-303 to -306. This is a sales and use tax requirement, not income tax withholding, since Wyoming has no income tax.

  • Nonresident prime contractors must file a surety bond or security equal to 3% plus 1% of contract payments, which is 4%. A standing $1,000,000 bond is an alternative.
  • Project registration. Nonresident primes, and resident primes that hire nonresident subcontractors, must register the project with the Department of Revenue within 15 days of starting work. Registration requires a bond or a cash deposit of at least 4%.
  • Withholding from subcontractors. A prime contractor who pays a nonresident subcontractor withholds 3% plus 1% (4%) of those payments until the Department of Revenue certifies that the subcontractor's tax is paid. Labor-only subcontractors are not covered by this withholding.
  • Late registration. A late registration carries a 1% penalty, and work can be enjoined until the bond is filed.

The 4% figure is the thread through all of this, so keep the sequence clear: confirm your residency status before you bid, register the project within 15 days of starting, and post the bond or deposit at 4% of the contract.

Step 8: Register construction machinery and keep your records

Construction machinery is registered annually with the county treasurer in place of a property tax under W.S. 31-18-203 to -208. Add that deadline to your calendar alongside your Secretary of State annual report and your city license renewals. Keep copies of every license, certificate, bond and receipt in one place, because cities, the state and your insurer may each ask for different documents.

Common mistakes to avoid

  • Assuming a state license exists. Wyoming does not license general contractors, plumbers or HVAC technicians at the state level. Your city license is what allows you to work.
  • Assuming one city license works everywhere. A Cheyenne license does not carry over to Casper, Gillette or any other city.
  • Skipping the Individual Qualified Supervisor. Cheyenne requires one for every company, and Laramie requires a Qualified Supervisor of Record. Naming someone who does not meet the standard can delay your license.
  • Using a drop box for your registered agent. A physical street address is required. A PO box may be added, but never used alone.
  • Charging sales tax on labor. Labor on real property is not taxable. Charging tax on it confuses customers and creates problems at audit.
  • Missing the 15-day project registration. A late registration carries a 1% penalty and can stop work until the bond is filed.
  • Letting the annual report lapse. The $60 minimum annual report is due on the first day of your anniversary month. Missing the 60-day window can lead to administrative dissolution.
  • Assuming the owner exemption applies to you. It covers only owner-occupied one-family dwellings and does not apply within three years of a prior owner permit.

What results to expect

Working through these steps in order gives most contractors a workable setup, though the timing depends on how quickly you gather documents. An online LLC filing is typically active as soon as you complete it. A paper filing may take up to 15 business days. City licensing timelines vary, and the cities named above set their own review periods, so ask when you apply. Once licensed, you may find that the process is mostly paperwork and renewals, with the annual report, city renewals and sales tax filings recurring on fixed schedules.

Expect the most friction in the nonresident bond process and in multi-city work, where each city can require a different insurance limit and a different supervisor. Plan those steps early so they do not hold up your first bid.
