If you’re asking “how to find employer identification number?”, you’re not alone. The Employer Identification Number (EIN)—also known as a Federal Tax ID—is issued by the IRS and is essential for filing taxes, opening business bank accounts, applying for licenses, and more.
1. Check IRS EIN Confirmation Letter
When you first applied for an EIN, the IRS sent a confirmation letter (CP 575). This document includes your 9-digit EIN and is often accepted as proof of your tax ID.
2. Look at Filed Tax Returns
If you’ve filed taxes previously, the EIN is listed on:
- Business income tax returns (Form 1120, 1065, etc.)
- Employment tax forms (like 941 or 940)
- W-2 and 1099 forms issued to employees or contractors
3. Check Business Bank Account Records
Many banks include your EIN in account opening paperwork or within business account settings online.
4. Search Official IRS or Government Databases
If your business is public or nonprofit, try:
- IRS Exempt Organizations Search Tool
- SEC EDGAR Database (for public corporations)
- State business entity search portals
These may reveal EINs tied to registered business entities.
5. Call the IR
If all else fails, you can call the IRS Business & Specialty Tax Line at 800-829-4933 (M–F, 7:00 am – 7:00 pm local time).
You must be an authorized party (owner, officer, or legal representative) to receive EIN details over the phone.
6. Ask Your Payroll or HR Department
If you’re an employee looking for your employer’s EIN, check your W-2 form, or contact your HR department or payroll provider directly.
Final Thoughts
Finding your Employer Identification Number is simple if you know where to look. Whether through IRS documents, tax filings, or by contacting the IRS directly, locating your EIN ensures smooth financial operations for your business.
