EIN Application: How to Apply Online for Free

Getting an Employer Identification Number (EIN) for your business is like getting a Social Security number for yourself — it’s how the IRS identifies your company for tax purposes. The good news? It’s completely free and takes about 15 minutes if you know what you’re doing.

An EIN is a nine-digit number (formatted like 12-3456789) that the IRS assigns to your business. You’ll need it to open a business bank account, hire employees, file tax returns, and handle most official business transactions. Even if you’re a single-member LLC with no employees, you’ll likely need an EIN eventually.

Here’s what happens if you skip this step: You can’t open a business bank account without mixing personal and business finances (which kills your liability protection if you’re an LLC or corporation). You can’t hire employees. You can’t properly file business tax returns. Basically, you’re stuck operating in a legal and financial gray area that creates problems down the road.

What You Need to Know

The EIN requirement is straightforward but has some nuances depending on your business structure.

Who needs an EIN:

All corporations and partnerships (required)
LLCs with multiple members (required)
Any business with employees (required)
Single-member LLCs that want to be taxed as an S-Corp or C-Corp (required)
Single-member LLCs that want to separate business and personal finances (recommended)

Who might not need one:

Sole proprietors with no employees can use their Social Security number
Single-member LLCs with no employees that are comfortable mixing personal and business banking (not recommended)

Timing matters. You can apply for an EIN as soon as your business is legally formed. For LLCs and corporations, that means after your state accepts your articles of organization or articles of incorporation. Don’t wait until you need it — get it done within a few weeks of formation.

The IRS processes EIN applications immediately for online applications submitted Monday through Friday, 7 AM to 10 PM Eastern. Outside those hours, you’ll get your EIN the next business day.

How to Handle It — Step by Step

Here’s exactly how to get your EIN directly from the IRS for free:

Step 1: Gather your information
You’ll need:

Your business legal name (exactly as it appears on your formation documents)
Business address (can be your home address)
Responsible party’s name and SSN (usually the business owner)
Business structure (LLC, corporation, partnership, etc.)
Reason for applying (starting a new business, banking purposes, etc.)
Business start date or acquisition date

Step 2: Go to the official IRS website
Navigate to IRS.gov and search for “Apply for EIN Online.” The official application is at www.irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online.

Warning: Many third-party websites charge $50-$300 to do what you can do for free. They often rank higher in search results than the official IRS site. Look for the .gov domain.

Step 3: Complete the online application
The SS-4 form is built into the online system. Answer each question carefully:

Business name must match your formation documents exactly
Choose your business structure from the dropdown menu
For “reason for applying,” select the option that best fits (usually “Started new business”)
Be consistent with dates and information

Step 4: Submit and receive your EIN
Click submit. If you applied during business hours (Monday-Friday, 7 AM-10 PM Eastern), you’ll get your EIN immediately. Print or save the confirmation notice — this is your official EIN document.

Step 5: Keep records
Save your EIN confirmation notice in your business records. You’ll need to provide this number constantly, so store it somewhere accessible. Consider adding it to your business contact template or storing it in your password manager.

The entire process takes 10-15 minutes if you have your information ready.

What It Costs

Getting an EIN directly from the IRS costs exactly $0. It’s completely free.

However, you might encounter these costs:

Third-party services charge $50-$300 to file for you (unnecessary)
If you lose your EIN and need the IRS to research it: $0 (they’ll help you find it for free)
Expedited processing: Not available (online applications are already immediate during business hours)

There are no penalties for applying late since there’s no specific deadline. But delaying your EIN application can create practical problems like being unable to open a business bank account or properly file taxes.

State-by-State Differences

EIN applications are federal, so the process is identical regardless of which state you formed your business in. However, some state-specific considerations affect timing:

States with fast formation processing:
Delaware, Wyoming, and Nevada typically approve LLC and corporation formations within 1-2 business days. You can apply for your EIN immediately after approval.

States with slower processing:
California, New York, and Illinois can take 2-4 weeks to approve formations. Don’t apply for your EIN until you receive confirmation that your business is officially formed.

Multi-state businesses:
If you plan to operate in multiple states, get your EIN in your formation state first. You’ll use the same EIN for tax purposes in other states, though you may need to register as a foreign entity.

State tax ID numbers:
Some states require separate state tax ID numbers in addition to your federal EIN. This is separate from the EIN application but worth noting:

California requires a separate state employer ID if you have employees
Texas requires a state taxpayer number for certain business types
New York requires state tax registration for most business entities

Check your state’s Department of Revenue website after getting your federal EIN to see if additional registrations are required.

Common Mistakes and How to Avoid Them

Mistake 1: Using third-party services unnecessarily
Many people pay $100+ for something that takes 15 minutes to do for free. Unless you’re using a comprehensive service that handles multiple steps (like business formation + EIN + compliance setup), there’s no reason to pay for EIN filing alone.

Mistake 2: Applying before your business is legally formed
You need your business to officially exist before getting an EIN. Wait until your state approves your Articles of Organization (LLC) or Articles of Incorporation (corporation).

Mistake 3: Inconsistent business names
Your EIN application must use your exact legal business name. If your LLC is “Smith Consulting LLC” on your Articles of Organization, don’t put “Smith Consulting” on the EIN application.

Mistake 4: Losing your EIN confirmation
Your EIN confirmation notice is important. Banks and other institutions often want to see the official IRS document, not just the number. Save multiple copies in different locations.

Mistake 5: Applying multiple times
If you don’t get immediate confirmation, don’t resubmit. Multiple applications for the same business create problems. Wait 24 hours, then call the IRS at 1-800-829-4933 if you need help.

Mistake 6: Using personal information for business applications
Use your business address and legal business name throughout the application. Don’t mix personal and business information unless specifically required (like the responsible party’s SSN).

FAQ

Can I apply for an EIN before forming my business?
No. Your business must be legally formed (LLC, corporation, etc.) before you can get an EIN. For sole proprietorships, you can apply as soon as you start business operations.

How long does an EIN last?
Forever. Once assigned, your EIN stays with your business permanently. You don’t need to renew it, and it doesn’t expire.

Can I change my EIN if I make a mistake?
The IRS rarely allows EIN changes. If you made an error on your application, you’ll likely need to use the EIN as assigned and update your business records accordingly. In cases of significant errors, you may need to close the incorrect EIN and apply for a new one.

Do I need a new EIN if I change my business structure?
Usually yes. Converting from an LLC to a corporation, or changing from single-member to multi-member LLC typically requires a new EIN. However, adding members to an LLC or changing business names usually doesn’t.

Can I get an EIN if I’m not a U.S. citizen?
Yes, but the process is more complex. Non-U.S. residents need to apply by mail or fax using Form SS-4, and you’ll need an Individual Taxpayer Identification Number (ITIN) or Social Security Number for the responsible party.

What if I need my EIN immediately outside business hours?
The online system only provides immediate EINs Monday-Friday, 7 AM-10 PM Eastern. Outside those hours, you can still submit your application, but you’ll receive your EIN the next business day.
