Whether you’re filing taxes or applying for a business loan, knowing where to find your Employer Identification Number (EIN) is essential. The EIN, issued by the IRS, uniquely identifies your business for tax and legal purposes—similar to how a Social Security Number identifies an individual.
Where to Find Your EIN
Here are the most common and secure ways to locate your EIN:
1. IRS EIN Confirmation Letter (CP 575)
When you first apply for an EIN, the IRS sends a confirmation letter. If you saved a physical or digital copy, your EIN will be listed at the top.
2. Tax Returns
Your EIN appears on your past business tax filings, including IRS forms like 1120, 1065, or 941.
3. Banking Documents
If you used your EIN to open a business bank account, it may be listed on your original account setup paperwork.
4. Payroll Records
Check pay stubs, payroll reports, or W-2s issued to employees—these usually include your EIN.
5. State or Local Business Filings
State registrations, licenses, or permits may display your EIN, especially if submitted with IRS documentation.
6. Contact the IRS
Call the IRS Business & Specialty Tax Line at 800-829-4933. Be prepared to verify your identity before they provide EIN details.
Where to Find an Employer’s EIN (If You’re an Employee)
If you’re looking for your employer’s EIN, try these:
- W-2 Form: Box ‘b’ shows your employer’s EIN.
- Old pay stubs: Sometimes the EIN appears on check stubs.
- Contact HR: Your employer’s human resources or payroll department can provide the EIN.
Final Thoughts
Knowing where to find your Employer Identification Number can save you time and prevent compliance issues. Keep your EIN stored securely for easy access during tax season or official business activities.
