Do I Have an EIN? How to Check and Verify Your Business EIN

Understanding whether your business has an Employer Identification Number (EIN) is crucial for compliance and operational efficiency. An EIN serves as a unique identifier for businesses, akin to a Social Security number for individuals, and is necessary for tax filing, opening bank accounts, and applying for licenses.

Searching Your Existing Business Records

To determine if your business already has an EIN, examine your business formation documents, such as articles of incorporation or organization. These foundational records, often filed with the Secretary of State or a similar regulatory body, may include the EIN if it was obtained during setup.

Check your internal accounting records as well. Financial statements, such as balance sheets and income statements, may reference the EIN, particularly if your business processes payroll or files taxes. Accounting software can also store this information, making a review of digital records efficient. If you work with an accountant or bookkeeper, they may also have this information on file, as the EIN is essential for tax preparation and financial documentation.

Reviewing Past Tax Filings

Tax filings are a reliable source for verifying your EIN. IRS forms like Form 941 for payroll taxes or Form 1120 for corporate income tax prominently display the EIN on the first page. State-specific tax filings, such as those for sales tax, may also include the number.

Organized tax records are critical for long-term compliance. The IRS recommends retaining copies of all filed tax returns for at least seven years, covering the statute of limitations for audits. Businesses that have undergone name changes, mergers, or acquisitions should carefully review these filings, as such events may have required a new EIN.

Checking Bank and License Documentation

Bank and license documentation can also help confirm your EIN. Financial institutions typically require the EIN when opening accounts, and it is often listed on bank statements or account-opening materials. If your business has multiple accounts, review all associated documentation thoroughly.

Licenses and permits may also reference your EIN. Regulatory bodies often require this number for operational permits or industry-specific licenses, such as food service certifications. Renewal notices or payment receipts from licensing authorities may also include the EIN.

Contacting the IRS for Verification

If other methods fail, contact the Internal Revenue Service (IRS) directly to verify your EIN. Call the IRS Business & Specialty Tax Line with verifiable information, such as your business’s legal name, address, and the owner’s Social Security Number or Individual Taxpayer Identification Number.

The IRS may require additional documentation, particularly if the inquiry is made by an authorized representative rather than the business owner. Submitting Form 2848, Power of Attorney and Declaration of Representative, can streamline the process. Check the IRS website for current procedures and downloadable forms to ensure compliance and avoid delays.
