Check Your IRS Confirmation Letter
When you first apply for an EIN, the IRS sends a confirmation letter, known as a CP 575 notice. This letter contains your unique EIN and serves as official documentation of your business’s tax ID. If you still have this letter in your business records, locating your EIN will be straightforward.
Review Your Tax Returns and Financial Documents
Your EIN is often included on business tax returns, including Forms 1040 (with Schedule C), 1065, 1120, or 1120S. If you have previously filed taxes, you can check these forms for your EIN. Additionally, business bank statements, payroll records, and previous correspondence with the IRS may also include this number.
Look at Business Licenses and Permits
Many business licenses, permits, and other official registrations require an EIN. If your business has applied for these documents, your EIN may be listed on the paperwork.
Check with Your Bank or Financial Institution
If you used your EIN to open a business bank account, your financial institution may have a record of it. Contact your bank’s customer service or check online banking statements to locate your EIN.
Call the IRS Business & Specialty Tax Line
If you cannot find your EIN through the methods above, you can contact the IRS Business & Specialty Tax Line at 800-829-4933. Be prepared to verify your identity by providing information about your business, such as its name, address, and the responsible party’s Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). The IRS representative will assist you in retrieving your EIN.
Use Your Business Credit Report
If your business has established credit, your EIN may be listed on your business credit report from agencies like Dun & Bradstreet, Experian, or Equifax.
Prevent Future Issues
To avoid losing track of your EIN, store it securely with your other essential business records. Consider keeping a digital and physical copy in separate, safe locations.
