A new West Virginia business may need more than one identification number. The Internal Revenue Service issues the federal Employer Identification Number (EIN). The West Virginia Tax Division issues a Business Registration Certificate and establishes identification numbers for applicable state tax accounts. These numbers serve different purposes and should not be treated as interchangeable.
Identify Which Tax ID Number the Business Needs
An EIN is generally needed for employers, corporations, partnerships, many LLCs, and other situations described by the IRS. Some sole proprietors use an EIN for business purposes even when federal rules do not require one. The correct answer depends on the entity and activity.
West Virginia generally requires a Business Registration Certificate before a person engages in business activity in the state. Registration also establishes the accounts needed for actual activities, such as sales and use tax or withholding. A business should select only the accounts that apply.
Prepare for the Federal EIN Application
- Complete the legal entity’s West Virginia formation or qualification first when applicable.
- Use the exact approved legal name, entity type, formation date, and addresses.
- Identify the responsible party and prepare the requested taxpayer identification number.
- Determine the reason for applying, accounting closing month, expected employees, and first wage date when applicable.
- Describe the principal business activity accurately.
Complete the EIN and Applicable State Registration
Apply through an official IRS route
Eligible applicants may use the IRS online EIN assistant at no charge. The online process must be completed in one session. Applicants who use Form SS-4 should check the current fax, mail, or international instructions immediately before filing.
Keep the federal confirmation
Save the EIN confirmation with the formation records and use the same legal name and entity facts in later accounts. Do not submit duplicate applications merely because a confirmation letter was misplaced; the IRS provides procedures for locating an existing number.
Register only for applicable West Virginia accounts
The One Stop Business Portal can coordinate applicable Secretary of State, Tax Division, and WorkForce West Virginia registrations. Paper applicants use the current WV/BUS-APP and any separate agency filings. Out-of-state remote sellers may have an eligible MyTaxes route.
Registration results can include a Business Registration Certificate and account identification numbers for the taxes that apply. A sales-tax account, withholding account, unemployment account, and federal EIN are distinct.
Avoid Common Tax ID Problems
Choosing the wrong state
This article concerns West Virginia. Do not use Virginia Tax registration merely because an older URL contains a “va-” prefix. Preserve the established URL, but follow West Virginia agencies and instructions.
Applying before the entity is formed
Form the legal entity first, then apply under the approved name. This helps keep federal and state records consistent.
Confusing an EIN with a state account
The EIN is federal. West Virginia’s certificate and tax-account IDs are state records. A bank, payroll provider, vendor, or agency may ask for one or more of them depending on the transaction.
Selecting every available tax type
Register accounts that correspond to the business’s actual activities. If the classification is unclear, use Tax Division guidance or qualified advice before creating unnecessary filing obligations.
Starting the online process unprepared
Gather the legal name, EIN, responsible parties, addresses, locations, activities, start dates, tax types, and employee facts before opening the One Stop or IRS process.
Final Decision Checklist
- Structure: Is the legal entity formed or qualified under the intended name?

- West Virginia certificate: Has the business identified the applicable Business Registration Certificate route?
- Tax accounts: Do the selected accounts match actual sales, employment, or other activities?
- Locations: Has each West Virginia business name or location been evaluated?
- Records: Are the EIN confirmation, state certificate, account notices, and formation documents retained together?
