How to Get an EIN (Employer Identification Number)
Starting a business involves numerous administrative steps, and obtaining an Employer Identification Number (EIN) is one of the most crucial early tasks you’ll need to complete. Whether you’re forming an LLC, corporation, or partnership, understanding how to get an EIN is essential for establishing your business’s legal and financial foundation.
An EIN serves as your business’s unique identifier with the Internal Revenue Service (IRS), similar to how a Social Security Number identifies individuals. This nine-digit number is required for filing tax returns, opening business bank accounts, hiring employees, and handling various other business transactions. Without an EIN, you’ll face significant obstacles in operating your business legally and efficiently.
In this comprehensive guide, you’ll learn everything about obtaining an EIN, from understanding when you need one to navigating the application process. We’ll cover the step-by-step procedures, associated costs, common pitfalls to avoid, and how formation services can simplify this process for new business owners.
Understanding the EIN: What You Need to Know
What Is an EIN?
An Employer Identification Number, also called a Federal Tax Identification Number, is a unique nine-digit identifier assigned by the IRS to businesses operating in the United States. The number follows the format XX-XXXXXXX and remains with your business throughout its lifetime, regardless of changes in ownership structure or business activities.
When Do You Need an EIN?
Most business entities require an EIN, but the specific requirements depend on your business structure:
- LLCs: Required if you have employees, multiple members, or elect corporate tax treatment
- Corporations: Always required, regardless of size or employee count
- Partnerships: Always required for tax filing purposes
- Sole Proprietorships: Required only if you have employees or want to separate personal and business banking
Legal Requirements and Implications
The IRS mandates EIN registration for specific business activities. Beyond basic entity requirements, you’ll need an EIN if you plan to open a business bank account, apply for business licenses, set up payroll, or establish business credit. Many banks and vendors require an EIN for business transactions, making it practically necessary even when not legally required.
Common Misconceptions
Many new business owners believe they can use their Social Security Number for all business purposes, but this creates unnecessary personal liability exposure and complicates accounting. Others assume EIN applications are complex or expensive, when the process is actually straightforward and free when done directly through the IRS.
Step-by-Step Process for Getting an EIN
Pre-Application Preparation
Before applying for an EIN, ensure you’ve completed your business formation process. You’ll need your entity type finalized, business name registered, and formation documents filed with your state. Having your operating agreement or corporate bylaws prepared, while not required for EIN application, demonstrates business legitimacy.
Required Information and Documents
Gather the following information before starting your application:
- Business Details: Legal business name, trade name (if different), business address, and mailing address
- Entity Information: Business structure (LLC, corporation, partnership, etc.) and state of formation
- Responsible Party: Name, Social Security Number, and address of the individual with control over the business
- Business Purpose: Brief description of your primary business activities
- Employee Projections: Expected number of employees within 12 months
Filing Methods and Timeline
The IRS offers several methods for obtaining an EIN:
Online Application (Recommended)
The fastest method involves using the IRS website’s online application system. This option is available Monday through Friday, 7:00 AM to 10:00 PM Eastern Time. You’ll receive your EIN immediately upon successful completion.
Telephone Application
Call the IRS Business & Specialty Tax Line at (800) 829-4933. This method provides same-day processing but requires staying on hold and completing the application verbally with an IRS representative.
Fax Application
Submit Form SS-4 via fax for processing within four business days. This option works well if you prefer written documentation of your application.
Mail Application
Send completed Form SS-4 by mail, expecting 4-5 weeks processing time. This is the slowest method but provides a complete paper trail.
Post-Application Steps
Once you receive your EIN, immediately save the confirmation document in your business records. This document serves as official proof of your EIN assignment. Update your business formation documents with the EIN, notify your registered agent if applicable, and begin using the number for all business transactions.
State-Specific Considerations
While EIN applications follow federal procedures, some states have additional requirements. Certain jurisdictions require EIN registration with state tax authorities, while others mandate specific business license applications that reference your EIN. Research your state’s requirements to ensure full compliance.
Costs & What to Expect
IRS Filing Costs
The IRS never charges for EIN applications when filed directly. Any fees associated with EIN acquisition come from third-party services, not the federal government. Be wary of websites charging for “expedited processing” or “guaranteed approval” – these are unnecessary for standard EIN applications.
Formation Service Fee Ranges
If you obtain your EIN through a business formation service, expect varying fee structures:
- Basic Services: $0–$50 for simple EIN applications as part of formation packages
- Premium Services: $50–$150 for EIN acquisition with additional business setup assistance
- Comprehensive Packages: $100–$300+ for EIN applications bundled with registered agent services, operating agreements, and ongoing compliance support
What’s Typically Included vs. Add-On Fees
Most formation services include EIN application as part of their standard formation packages. However, some providers charge separately for expedited processing, business banking assistance, or tax election filings. Review package details carefully to understand what’s included versus additional fees.
Hidden Costs to Watch For
Some providers advertise low-cost EIN services but charge extra for basic necessities like document delivery, customer support, or correction services. Others require monthly fees for “EIN monitoring” or “compliance tracking” that provide minimal value for most small businesses.
Total Cost Estimates by Approach
DIY Approach: Free when applying directly through the IRS, requiring only your time investment
Formation Service: $0–$300+ depending on provider and package selection
Attorney Assistance: $200–$500+ for professional guidance, typically unnecessary for straightforward applications
Choosing a Formation Service for EIN Assistance
Key Factors to Consider
When selecting a service to help with EIN applications, prioritize these elements:
Pricing Transparency: Look for providers with clear, upfront pricing without hidden fees or mandatory add-ons. Services like ZenBusiness and Northwest Registered Agent typically offer transparent pricing structures.
Included Documentation: Quality services provide complete EIN documentation, confirmation letters, and clear instructions for next steps.
Processing Speed: While the IRS determines actual processing time, good services submit applications promptly and provide regular status updates.
Customer Support: Choose providers offering multiple support channels and knowledgeable representatives who understand business formation requirements.
Service Tiers and Inclusions
Basic Tier ($0–$100): Simple EIN application submission with basic documentation
Standard Tier ($100–$250): EIN application plus registered agent services, basic operating agreement templates
Premium Tier ($250–$500+): Comprehensive packages including EIN, multiple state filings, ongoing compliance support, and business banking assistance
Red Flags to Avoid
Avoid providers that pressure immediate purchases, require payment before explaining services, or make unrealistic promises about processing times. Be cautious of services advertising “guaranteed approval” – legitimate EIN applications are rarely denied when properly completed.
Comparing Providers Effectively
Research multiple providers including established names like Incfile, Bizee, and Swyft Filings. Compare not just pricing but included services, customer reviews, and post-formation support options. Many comparison platforms provide side-by-side analysis of features and costs across different providers.
Common Mistakes to Avoid
Choosing the Wrong Business Entity
Many entrepreneurs apply for EINs before finalizing their entity structure. Changing entity types after obtaining an EIN can create tax complications and require additional paperwork. Finalize your business structure before applying.
Providing Incorrect Information
Simple errors in business names, addresses, or responsible party information can delay processing or create future complications. Double-check all information against your formation documents before submitting.
Using Third-Party Scam Sites
Numerous websites mimic the official IRS site while charging unnecessary fees. Always verify you’re using the legitimate IRS website (irs.gov) or working with reputable formation services.
Neglecting Record Keeping
Failing to properly store EIN documentation creates problems when opening bank accounts or filing taxes. Maintain both digital and physical copies of all EIN-related documents.
Misunderstanding Tax Implications
An EIN doesn’t automatically determine your tax classification. LLCs, for example, can elect different tax treatments that require separate filings. Understand how your EIN relates to your overall tax obligations.
Overpaying for Unnecessary Services
While formation services provide value, simple EIN applications rarely require expensive premium packages. Evaluate whether additional services justify higher costs for your specific situation.
Frequently Asked Questions
How long does it take to get an EIN?

Can I get an EIN before forming my business?

What happens if I make a mistake on my EIN application?
