How to Get an EIN in Wyoming

An Employer Identification Number (EIN) is a nine-digit federal tax identification number issued by the Internal Revenue Service (IRS) to businesses operating in the United States. In Wyoming, your EIN is essential for hiring employees, opening a business bank account, and filing federal tax returns. This article walks you through the process of obtaining an EIN in Wyoming, from preparing your application to receiving your number.

Who Needs an EIN in Wyoming?

An EIN is required if your Wyoming business meets any of these conditions:

• You have employees (or plan to hire them)
• You operate as a partnership, S corporation, C corporation, or LLC with more than one member
• You are a single-member LLC that has chosen to be taxed as a corporation
• You have a Keogh plan or are involved in certain types of trusts
• You are a nonprofit organization
• You withhold income taxes from employees or other workers

Solo self-employed individuals and sole proprietors can file taxes using their Social Security Number instead of an EIN, but many choose to obtain one for privacy and banking purposes.

What You'll Need Before Applying

Gather these materials before you start the application. Having everything ready reduces errors and speeds up processing:

• Your Social Security Number (if you are the principal owner or responsible party)
• Legal business name exactly as it appears on your Wyoming Articles of Organization or Articles of Incorporation
• Doing Business As (DBA) name, if applicable
• Business address in Wyoming (a physical street address; PO boxes are not accepted)
• Mailing address if different from business address
• Business type and structure (LLC, corporation, partnership, etc.)
• Reason for applying (starting a new business, hiring employees, etc.)
• Expected date you will pay wages to employees
• Effective business start date
• Principal officer's name and title (if applicable)

If you have recently formed an LLC in Wyoming, your Articles of Organization filed with the Wyoming Secretary of State will contain most of this information. You can search for your business filing using the WyoBiz filing search.

Step-by-Step: How to Apply for an EIN Online (Fastest Method)

The IRS online application system is available Monday through Friday, 7:00 a.m. to 10:00 p.m. Eastern Time. You can receive your EIN immediately upon approval. Follow these steps:

Step 1: Go to the IRS Application Portal

Visit the official IRS EIN application page at www.irs.gov/ein. Click "Apply for an EIN Online" to access the Business and ITIN EIN Subscription Service (BITE).

Step 2: Select Your Entity Type

From the dropdown menu, choose your Wyoming business structure. For example:

• Limited Liability Company (LLC)
• Corporation (for-profit or nonprofit)
• Partnership
• Sole proprietorship
• Trust

Select the option that matches your business formation exactly. This determines the tax classification and how your business will be taxed at the federal level.

Step 3: Enter Your Business Information

Provide accurate details about your Wyoming business:

• Legal business name (as it appears on your Articles of Organization or incorporation papers)
• Trade name or DBA (if you operate under a different name)
• Physical business address (must be a street address in Wyoming; no PO boxes)
• Mailing address (if different)
• County where your principal place of business is located
• Date your business began operations (or will begin)

Accuracy is critical here. Mismatches between your Articles of Organization filed with the Wyoming Secretary of State and your EIN application can delay processing or cause your application to be rejected.

Step 4: Identify the Responsible Party

The responsible party is the individual with control and authority over the business. This is typically the owner, manager, or principal officer. Provide:

• Full legal name
• Social Security Number
• Date of birth
• Title or role (e.g., Member, Manager, President)

The responsible party does not have to be a U.S. citizen, but they must have a valid identification number (Social Security Number or ITIN).

Step 5: Explain Your Reason for Applying

Select the primary reason you need an EIN from the IRS list. Common reasons include:

• Starting a new business
• Hiring employees
• Opening a business bank account
• Forming an LLC, corporation, or partnership
• Changing the structure of your business
• Purchasing an existing business

If you are forming a Wyoming LLC with multiple members, select "Forming a partnership or LLC." If you will have employees, also select "Hiring employees."

Step 6: Review and Confirm

The IRS application portal will display a summary of your information. Review every detail carefully for accuracy. Do not proceed until you are certain everything is correct.

Step 7: Submit and Receive Your EIN

Click submit. If your application is approved, the IRS will display your nine-digit EIN immediately on your screen. You can print this confirmation for your records. Write down your EIN and save it in a secure location.

The IRS will also email you a confirmation document. Keep this email in your business records. You do not receive a physical EIN card in the mail; the number is your tax identifier.

Alternative Application Methods

If you prefer not to apply online or need to apply outside business hours, the IRS offers these options:

By Phone

Call the IRS Business and Specialty Tax Line at 1-800-829-4933, Monday through Friday, 7:00 a.m. to 10:00 p.m. Eastern Time. The IRS will assign an EIN over the phone, but you will not receive written confirmation until it arrives by mail (typically 2 to 4 weeks). Have all your business information ready before calling.

By Mail

Complete Form SS-4 (Application for an Employer Identification Number). Download it from www.irs.gov/forms and search for "SS-4." Mail it to the IRS address listed on the form for your region. Processing typically takes 4 to 6 weeks. This method is slow but works if you cannot access the online system.

By Fax

Some IRS offices accept faxed Form SS-4 applications. Call the Business and Specialty Tax Line to confirm if fax filing is available and to get the correct fax number for your region. Processing by fax takes 1 to 2 weeks.

Wyoming Tax Requirements After Your EIN

Obtaining an EIN is a federal process, but Wyoming has separate tax obligations. After you receive your EIN, complete these state-level registrations:

Sales and Use Tax License

If your Wyoming business makes taxable sales, you must register for a sales and use tax license from the Wyoming Department of Revenue, Excise Tax Division. Wyoming's state sales tax rate is 4%. Visit excise-tax-div.wyo.gov to apply. There is a $60 non-refundable application fee. This registration is separate from your EIN.

No Corporate Income Tax

Wyoming does not impose a corporate income tax, personal income tax, or franchise tax. This means your federal EIN is your primary tax identifier at the state level, and you will not owe state income tax on business profits.

Annual Report

If you registered your business as a Wyoming LLC or corporation with the Secretary of State, you must file an annual report every year. The annual report fee is $60 (or two-tenths of one mill on the dollar of Wyoming assets, whichever is greater, for LLCs). This is not an EIN-related requirement but is mandatory for all registered entities.

Timeline and Processing

Processing time depends on your application method:

• Online application: EIN issued immediately (same day), usually within minutes
• Phone application: EIN assigned over the phone; written confirmation arrives in 2 to 4 weeks
• Fax application: 1 to 2 weeks
• Mail application: 4 to 6 weeks

The application is free regardless of which method you choose. Do not pay any processing fees to the IRS; legitimate EIN applications have no cost.

Common Mistakes to Avoid

Mistake 1: Mismatched Business Names

Your EIN application must use the exact legal business name from your Wyoming Articles of Organization or Incorporation. If you write your name differently on the EIN form than it appears in your state filing, the IRS may reject the application or assign an EIN to a name that does not match your official registration. Result: complications when opening business bank accounts or filing taxes. Always copy the legal name directly from your Secretary of State filing.

Mistake 2: Using a PO Box as Your Business Address

The IRS requires a physical street address for your principal place of business. A PO box is not acceptable. If you run your business from home, use your residential street address. The IRS will validate the address and may reject the application if it appears invalid or incomplete.

Mistake 3: Delaying the Application Until After You Hire Employees

You must have an EIN before you hire your first employee or issue a W-2. If you are planning to add staff, obtain your EIN before you bring anyone on. Applying after payroll begins creates record-keeping problems and tax filing issues. Apply as soon as you form your LLC or corporation.

Mistake 4: Assuming Your EIN is Your Wyoming Tax ID

Your EIN is a federal tax identification number. Wyoming does not issue a separate state "tax ID." However, you must register separately for sales tax if you sell taxable goods or services. Many new business owners confuse these and think an EIN covers all tax obligations. It does not. The $60 sales tax registration is a separate, required step.

Mistake 5: Falling for EIN Application Scams

Scammers pose as IRS representatives and charge $50 to $300 to "help" you get an EIN. The EIN application is always free directly from the IRS. Never pay a third party for an EIN. Use only official IRS channels: www.irs.gov/ein, the phone number 1-800-829-4933, or IRS mail addresses.

What to Do With Your EIN

Once you have your EIN, keep it safe and use it for:

• Opening a business bank account
• Filing federal income tax returns (Form 1120, 1120-S, 1065, or 990, depending on your structure)
• Hiring employees and filing payroll taxes
• Applying for business licenses and permits
• Registering for state sales tax (if applicable)
• Obtaining business credit and loans
• Filing annual reports with the Wyoming Secretary of State

You may need your EIN when corresponding with the IRS, your accountant, or your bank, so store it with your other important business documents.
