How to Get a Tax ID Number in West Virginia for a New Business

To get a tax ID number for a new business in West Virginia, first separate the federal EIN from any state tax registration the business may need. The IRS issues the federal Employer Identification Number (EIN). State tax accounts are handled separately by the state where the business has tax obligations.

West Virginia and Virginia are different jurisdictions. The federal EIN rules below apply to eligible businesses nationwide, including those in West Virginia. However, the Virginia registration details in this article apply only if the business is actually located in, employs people in, sells in, or otherwise has relevant tax obligations in Virginia. A West Virginia business should not register with Virginia Tax merely because the state names are similar.

Identify Which Tax ID Number the Business Needs

“Tax ID number” can refer to more than one identifier. A new owner should identify the purpose of the number before starting an application.

A business may need a federal EIN, one or more state tax accounts, or both. Obtaining an EIN does not by itself establish every state tax account the business might need. Likewise, registering an LLC or corporation is not the same as completing federal and state tax registration.

If the business is in West Virginia, confirm that applications and account selections are for West Virginia. If “West Virginia” was entered by mistake and the business is actually in Virginia, consult the Virginia Tax ID Number Guide for Startups.

Prepare for the Federal EIN Application

The IRS issues EINs directly through its online EIN tool at no charge. Before applying, settle the business’s legal structure and identify the person who will act as the responsible party.

An LLC, partnership, corporation, or tax-exempt organization should be formed through the state before its EIN application is submitted. Applying before forming one of these entities may delay the EIN application. This sequencing helps ensure that the legal name and entity type used on the EIN application match the newly formed organization.

For the IRS online tool, the principal place of business must be in the United States or a U.S. territory. The responsible party must have an SSN or ITIN, and the person submitting the application must be that responsible party or an authorized representative.

Gather the following information before opening the online application:

• The entity’s exact legal name and any trade name used in the application
• The business mailing and physical addresses
• The selected entity type
• The responsible party’s identifying information
• A clear description of the business’s principal activity
• Information about why the EIN is being requested

Review names, addresses, and entity selections against the business’s formation records. Small inconsistencies can create confusion later when the owner opens financial accounts or completes state registrations.

Complete the EIN and Applicable State Registration

Apply online through the IRS

The IRS online EIN application must be completed in one session and cannot be saved. It expires after 15 minutes of inactivity, so preparing the information in advance is important. If the application is approved, the EIN is issued immediately online. Save the resulting confirmation with the business’s permanent records.

The IRS limits EIN issuance to one EIN per responsible party per day. This limit applies across application methods, including online, telephone, fax, and mail. An owner organizing multiple entities should plan around that restriction rather than repeatedly submitting applications on the same day.

Use Form SS-4 when applying by fax or mail

Applicants may use Form SS-4 to apply by fax or mail. For an applicant whose principal business, office, agency, or legal residence is in a state or the District of Columbia, the IRS mailing address is Attn: EIN Operation, Cincinnati, OH 45999, and the fax number is 855-641-6935.

Complete the form using the entity’s legal information and retain a copy of the submitted form. Do not submit conflicting applications through multiple channels simply because a number has not yet been received.

Register only in the applicable state

After obtaining the EIN, determine whether the business must establish state tax accounts. For a West Virginia business, use the appropriate West Virginia process. The Virginia procedures below are relevant only when the business has applicable Virginia tax obligations.

All new businesses registering with Virginia Tax are required to register online. A business that cannot register online for a reason listed by the agency must instead submit Form R-1 by mail or fax.

Virginia Tax’s online registration requests the FEIN, information about the primary account user and responsible party, business details, entity type, NAICS code, applicable tax types, and the date business begins for each tax type. Preparing those items before starting can reduce interruptions.

Virginia Tax identifies retail sales tax, use tax for remote or out-of-state dealers with nexus, employer withholding for businesses with Virginia employees, and corporate or pass-through entity income tax as common registration types. These are examples rather than accounts that every business must select. Applicability depends on the business’s activities and Virginia tax obligations.

After registration, Virginia Tax issues a Virginia Tax account number for each registered tax type. A business registered to collect retail sales or use tax also receives a sales tax certificate, and online registrants are automatically enrolled in a business online-services account. Owners who specifically need that registration can review the Virginia Sales Tax Registration Guide for New Businesses.

Avoid Common Tax ID Problems

Choosing the wrong state

Do not treat “Virginia” as an abbreviation or shortened reference to “West Virginia.” Confirm the jurisdiction displayed on every state website, form, certificate, and account notice. If the company operates across state lines, analyze each state separately rather than assuming that one registration covers both.

Applying before the entity is formed

If the business will be an LLC, partnership, corporation, or tax-exempt organization, complete state formation first. Then use the finalized legal name and entity type on the EIN application.

Confusing an EIN with a state account

An EIN is federal. A state account number corresponds to a state-administered tax type. Keep the EIN confirmation, formation documents, state registration notices, and tax certificates labeled separately so that the correct identifier is used when requested.

Selecting every available tax type

A registration menu may present several possible accounts, but that does not mean all of them apply. Base selections on what the business actually does, where it operates, whether it has employees, and what it sells. When the answer depends on nexus, entity classification, or another legal determination, seek advice based on the business’s particular facts.

Starting the online EIN application unprepared

Because the online application cannot be saved and expires after inactivity, verify the necessary details before beginning. Avoid guessing at the legal name, entity type, responsible party, or principal activity merely to complete the session.

Final Decision Checklist

• Jurisdiction: Is the new business in West Virginia, Virginia, or operating in both states?
• Identifier: Is the request for a federal EIN, a state tax account, or both?
• Entity status: If forming an LLC, partnership, corporation, or tax-exempt organization, has state formation been completed before the EIN application?
• Responsible party: Is the online applicant the responsible party or an authorized representative, and does the responsible party have an SSN or ITIN?
• Application readiness: Are the legal name, addresses, entity type, responsible-party details, and business activity information ready before opening the IRS tool?
• State obligations: Has the owner evaluated which state tax accounts correspond to the business’s actual activities rather than selecting every account shown?
• Records: Is there a secure place to retain the EIN confirmation, formation documents, state account notices, and any sales tax certificate?

For a West Virginia startup, the practical sequence is to form the chosen legal entity when applicable, obtain the federal EIN, and then complete only the West Virginia or other state registrations that match the company’s activities. Use Virginia Tax procedures only when the business has a genuine Virginia registration obligation.
