Navigating the world of business compliance can be challenging, especially when it comes to tax identification. One of the most critical first steps for any business in the United States is completing the EIN application process. Whether you’re forming an LLC, incorporating, or hiring employees, obtaining an EIN Number (Employer Identification Number) from the Internal Revenue Service (IRS) is essential.
This guide provides a clear, step-by-step walkthrough of the EIN application process, ensuring you understand the requirements, avoid common pitfalls, and submit a successful application.
What is an EIN and Why is the EIN Application Necessary?
An EIN, also known as a Federal Tax Identification Number, is a unique nine-digit number assigned by the IRS to identify your business entity for tax purposes. Think of it as a Social Security Number for your company.
Completing the EIN application is mandatory if your business:
- Has employees.
- Files business tax returns (e.g., employment, excise, or alcohol/tobacco/firearms returns).
- Operates as a corporation or partnership.
- Withholds taxes on income (other than wages) paid to a non-resident alien.
- Has a Keogh plan (a tax-deferred pension plan).
- Is involved in trusts, estates, or certain non-profits.
Even if not strictly required, most businesses apply for an EIN to open a business bank account, apply for business licenses, and establish credit.
Step-by-Step EIN Application Process
Follow these steps to complete your EIN application successfully:
Step 1: Determine Your Eligibility
Before starting the EIN application, ensure you qualify. You must have a valid reason to need an EIN, and the “responsible party” (the person who controls, manages, or directs the entity and its assets) must have a valid Taxpayer Identification Number (TIN), which for non-U.S. residents is addressed by writing “Foreign” on the form.
Step 2: Gather Required Information
To complete the EIN application form (SS-4), you’ll need:
- Your business’s legal name and trade name (if any).
- Business address (a U.S. address is required).
- Formation date.
- Type of legal entity (LLC, Corporation, Partnership, Sole Proprietorship, etc.).
- Principal business activity.
- Highest number of employees expected in the next 12 months.
- Name and TIN of the “Responsible Party.”
Step 3: Complete the EIN Application Form (SS-4)
The EIN application is submitted using Form SS-4. You can access it on the IRS website.
Key Points for Form SS-4:
- Line 7b (SSN or ITIN of Responsible Party): If the responsible party is a non-U.S. resident without an SSN or ITIN, write “Foreign” in this box. This is crucial for foreign EIN applications.
- Accuracy is Key: Ensure all information matches your official business documents exactly.
Step 4: Submit Your EIN Application
There are several ways to submit your EIN application, but not all are available to everyone:
- Online EIN Application (Fastest for U.S. Entities):
- Available only to businesses formed in the U.S. or U.S. territories whose principal business, office, or agency is located in the U.S., and where the “responsible party” has a valid U.S. SSN, ITIN, or EIN.
- The process takes about 10-15 minutes, and you receive your EIN immediately upon validation.
- Not available for most foreign applicants.
- Fax or Mail the SS-4 Form:
- Complete Form SS-4 and fax or mail it to the appropriate IRS office.
- Fax: Generally faster (4 business days).
- Mail: Can take up to 4 weeks.
- You will receive a CP 575 notice by mail.
- Apply via an Authorized IRS Representative (Best for Foreign Entities):
- This is the recommended method for international businesses.
- Appoint a U.S.-based representative (like an accountant or a service such as SpeedEIN).
- The representative uses your information to call the IRS’s international EIN line and completes the EIN application over the phone.
- Benefits: Fast turnaround (1-3 days), high success rate, expert guidance, and immediate EIN issuance.
Common EIN Application Mistakes to Avoid
A poorly filled-out EIN application can lead to delays or rejection. Avoid these common errors:
- Incorrect Entity Type: Selecting the wrong business structure.
- Inconsistent Business Name: The name on the SS-4 must match state filings exactly.
- Missing “Foreign” Designation: For non-residents, failing to write “Foreign” on Line 7b.
- Invalid U.S. Address: Providing an incorrect or non-operational U.S. mailing address.
- Incomplete Information: Leaving required fields blank.
EIN Application for Foreign Entities: Special Considerations
If you’re applying for an EIN application as a foreign-owned U.S. business (e.g., a foreigner forming an LLC), remember:
- You do not need an SSN or ITIN.
- The “Foreign” designation on Form SS-4 is mandatory.
- The authorized representative method is the most efficient way to apply.
After Your EIN Application: What’s Next?
Once your EIN application is processed:
- You will receive your EIN Number.
- The IRS will send Form CP 575 (EIN Assignment Notice) to the U.S. address on file. Keep this document secure.
- Use your EIN to open a bank account, file taxes, and conduct business.
