What is an EIN and Why is it Important?
An EIN identifies your business for tax purposes․ It’s essential for virtually all formal business operations and federal tax filings․ Without it, you cannot fulfill many legal and financial obligations as a business․
When is an EIN Required?
While sole proprietors without employees might use their SSN, an EIN is mandatory if your business:
- Has employees․
- Is structured as a corporation or partnership․
- Files employment, excise, or alcohol, tobacco, and firearms taxes․
- Withholds taxes on income (other than wages) for a non-resident alien․
- Has a Keogh plan․
- Is a trust (excluding certain grantor trusts), IRA, tax-exempt organization, farmers’ cooperative, or real estate mortgage investment conduit․
How to Apply for an EIN
The IRS provides several methods for obtaining an EIN․
Online Application (Recommended)
This is the fastest method․ Available during specific IRS operational hours, the online application provides an EIN immediately upon successful validation․ The responsible party must have a valid SSN, ITIN, or existing EIN․ This is suitable for entities whose principal business is in the U․S․ or U․S․ Possessions․
Fax Application
Complete Form SS-4 and fax it to the appropriate IRS number․ Expect processing to take approximately four business days, with the EIN being faxed back․
Mail Application
Send a completed Form SS-4 via mail․ This is the slowest option, with processing times extending several weeks․ Ensure accuracy to prevent delays․
Telephone Application (International Applicants)
For applicants outside the U․S․, an EIN can be obtained by phone․ Have a completed Form SS-4 ready to answer questions; the EIN is assigned during the call․
Information Needed for Application
To apply, you’ll generally need:
- Business’s legal name and mailing address․
- Type of entity (e․g․, sole proprietorship, corporation)․
- Reason for applying․
- Responsible party’s name and Taxpayer Identification Number (SSN, ITIN, or existing EIN)․ This individual ultimately owns or controls the entity․
Finding an Existing EIN
If you’ve misplaced your EIN, here’s how to find it:
- Review Business Documents: Check past tax returns, IRS letters, business licenses, permits, or bank statements for your business account․ The EIN is typically on these․
- Contact the IRS: Call the IRS Business & Specialty Tax Line․ An IRS representative can provide it after verifying your identity․
- Check with Your Bank: Your bank likely has your EIN if you opened a business account there․
- Public Records: For public companies or some non-profits, the EIN might be publicly discoverable․ Less reliable for private businesses․
Common Mistakes to Avoid
- Duplicate Applications: Do not apply for a new EIN if one has already been issued, unless there’s a major change in business structure․ This causes confusion․
- Incorrect Information: Ensure all application details are accurate and consistent with official records to avoid processing delays․
- Unnecessary Application: Only apply for an EIN if your business truly requires it․
An EIN is a vital component of business identity and compliance in the U․S․ Whether starting a new venture today or needing to retrieve a lost number, understanding the application process and knowing where to search ensures smooth federal tax compliance․
