How to Apply for an EIN for Your LLC (Free IRS Guide)
Quick Take
Getting an EIN (Employer Identification Number) for your LLC takes about 15 minutes and can be done completely free through the IRS website. You’ll walk away with a nine-digit tax ID number that your business needs for everything from opening a bank account to filing taxes.
This is one of the most straightforward parts of setting up your business — much easier than the LLC formation itself. By the end of this guide, you’ll have your EIN in hand and know exactly what to do with it.
Before You Start
What You’ll Need
You need your LLC’s formation documents — specifically your articles of organization (the document that officially creates your LLC) or your state filing confirmation. The IRS will ask for your LLC’s exact legal name, formation date, and state of formation.
Have the responsible party’s information ready. This is typically you as the LLC owner, but it’s the person who controls the LLC’s finances and operations. You’ll need their full legal name, SSN, and address.
Know your business structure details. Single-member LLC? Multi-member LLC? The IRS treats these differently for tax purposes, and you’ll need to specify.
How Long This Takes
The actual application takes 10-15 minutes if you have everything ready. The IRS processes EIN applications immediately when filed online — you get your number right away.
Watch out for processing delays if you apply by mail or fax. Those methods can take 4-5 weeks. Stick with the online application unless you’re applying from outside the US.
Why This Matters for Your Business
Your EIN is your business’s Social Security number. Banks require it to open business accounts. Vendors and clients need it for 1099s. The IRS uses it to track your business taxes.
Even if you’re a single-member LLC that doesn’t plan to have employees, get an EIN anyway. It protects your personal SSN and makes your business look more professional.
Step-by-Step Process
Step 1: Go to the Official IRS Website
Navigate to IRS.gov and search for “EIN application” or go directly to the EIN application portal. You want the page titled “Apply for an Employer Identification Number (EIN) Online.”
Critical warning: Dozens of third-party websites charge $50-200 to file the same free IRS form. Make sure you’re on IRS.gov — the URL should start with “www.irs.gov.” These scam sites often rank higher in Google than the actual IRS page.
The IRS system is only available Monday through Friday, 7 AM to 10 PM Eastern. If you try to access it outside these hours, you’ll see an error message.
Step 2: Start the Application
Click “Apply Online Now” to begin. The system will ask you to confirm that you’re authorized to apply for an EIN for this entity. Click “Continue.”
You’ll see a screen asking about the type of entity. Select “Limited Liability Company (LLC)” from the dropdown menu.
Time estimate: 2 minutes
Step 3: Enter Your LLC Information
The system asks for your LLC’s legal name exactly as it appears on your Articles of Organization. Get this exactly right — even extra spaces or punctuation differences can cause problems later.
Enter your state of formation and the date you filed your Articles of Organization. The date format is MM/DD/YYYY.
If your state hasn’t processed your LLC filing yet, stop here. Wait until you receive confirmation from your state before applying for an EIN. The IRS may verify your LLC exists with your state.
Time estimate: 3 minutes
Step 4: Provide Business Details
The system asks “What is the reason you are applying for an EIN?” Select “Started a new business” unless you’re applying because you need to change how your existing LLC is taxed.
For “Type of entity,” select “Limited Liability Company (LLC)” again.
Number of members: This is crucial for tax purposes. Single-member LLCs are taxed as sole proprietorships by default. Multi-member LLCs are taxed as partnerships by default. Answer honestly — this affects your tax treatment.
Time estimate: 2 minutes
Step 5: Enter the Responsible Party Information
The responsible party is the person who ultimately controls the LLC. For most small LLCs, this is the primary owner or managing member.
Enter their full legal name, SSN, and address. This person will be associated with this EIN permanently, so choose carefully if you have multiple LLC members.
Common mistake: Don’t use your attorney’s or accountant’s information here unless they actually control your business operations.
Time estimate: 3 minutes
Step 6: Confirm Your Business Address
Enter your LLC’s principal business address. This can be your home address if you operate from home — it doesn’t have to be a commercial address.
If you want IRS correspondence sent to a different address (like your accountant’s office), enter that as the mailing address. Otherwise, check the box to use the same address for both.
Time estimate: 2 minutes
Step 7: Review and Submit
The system shows a summary of all information you entered. Review everything carefully — you can’t easily change this information later without contacting the IRS directly.
Pay special attention to:
- LLC name spelling and punctuation
- State of formation
- Responsible party SSN
- Number of LLC members
Click “Continue” to submit your application.
Time estimate: 2 minutes
Verify It Worked
Immediate Confirmation
If successful, you’ll see a confirmation screen with your nine-digit EIN. The format is XX-XXXXXXX (two digits, hyphen, seven digits).
Print or screenshot this confirmation page immediately. The IRS doesn’t email you a copy, and you’ll need this number right away for banking and other business setup tasks.
Official Documentation
The IRS will mail Form 147C (EIN Confirmation Letter) to your business address within 1-2 weeks. This is your official documentation, but you don’t need to wait for it to start using your EIN.
If you need official documentation immediately for banking, the confirmation screen printout is usually acceptable to banks as temporary proof while you wait for the official letter.
What to Do If It Didn’t Work
“Your session has timed out”: The IRS system times out after periods of inactivity. Start over — your information wasn’t saved.
“Entity already has an EIN”: This means someone already got an EIN for your LLC. Contact the IRS at 1-800-829-4933 to get your existing number.
“Cannot verify LLC with state”: Your state hasn’t processed your LLC formation yet, or there’s a mismatch in the name/date. Double-check your information or wait a few more days after state filing.
Common Mistakes
1. Using Third-Party Paid Services
Why it happens: These services advertise heavily and often rank higher than the IRS website in search results.
How to avoid it: Only use IRS.gov. The EIN application is always free when filed directly with the IRS.
Quick fix: If you already paid a service, you still get a valid EIN. Just remember it’s free next time.
2. Wrong LLC Name
Why it happens: People use their DBA name or a shortened version instead of the exact legal name from their Articles of Organization.
How to avoid it: Use the exact name from your state filing confirmation, including punctuation and spacing.
Quick fix: You’ll need to contact the IRS to correct this. It’s easier to start over with a new application if you catch it immediately.
3. Incorrect Member Count
Why it happens: Confusion about whether spouses count as separate members or uncertainty about LLC structure.
How to avoid it: Count actual LLC members as listed in your operating agreement. Spouses are separate members unless the LLC is owned by one spouse individually.
Quick fix: This affects your tax treatment. Contact the IRS or a CPA if you need to correct it — this isn’t just a paperwork error.
4. Wrong Responsible Party
Why it happens: Using an attorney, accountant, or family member who doesn’t actually control the business.
How to avoid it: Use the person who has ultimate authority over the LLC’s operations and finances — typically the managing member.
Quick fix: The IRS allows responsible party changes, but it requires paperwork. Get it right the first time.
5. Not Saving Confirmation
Why it happens: People assume they’ll get an email confirmation or can log back in to retrieve it.
How to avoid it: Print or screenshot the confirmation page immediately. The IRS doesn’t provide online account access to retrieve this later.
Quick fix: Wait for the mailed confirmation letter or call the IRS business line to request a duplicate.
What to Do Next
Open Your Business Bank Account
Your EIN is the key to separating business and personal finances. Most banks require an EIN to open business accounts, even for single-member LLCs.
Call banks in advance to ask what documents they need. Some want to see the official IRS letter rather than just the confirmation printout.
Set Up Business Credit
Your EIN lets you build business credit separate from your personal credit. Start with vendors who report to business credit agencies — office supply stores, gas cards, and business credit cards are good starting points.
Understand Your Tax Obligations
Single-member LLCs are taxed as sole proprietorships by default — profits and losses flow through to your personal tax return. You’ll file Schedule C with your Form 1040.
Multi-member LLCs are taxed as partnerships by default — the LLC files Form 1065, and members receive K-1s for their personal returns.
Both structures can elect S-Corp taxation by filing Form 2553, which can save self-employment taxes if your LLC is profitable enough.
Consider Quarterly Tax Payments
Unlike employees who have taxes withheld, LLC owners typically pay estimated taxes quarterly. Set aside 25-30% of profits for taxes if you’re unsure how much you’ll owe.
Get Professional Help for Complex Situations
If your LLC has multiple members, significant startup costs, or you’re considering the S-Corp election, talk to a CPA or tax attorney. These decisions affect your taxes for years and are worth getting right.

FAQ
Do I need an EIN if I’m the only member of my LLC?
Yes, you should get one even as a single-member LLC. While the IRS doesn’t require it unless you have employees, banks typically require an EIN for business accounts, and it protects your personal SSN from appearing on business documents.
Can I apply for an EIN before my state approves my LLC?
No, wait until your state processes your Articles of Organization. The IRS may verify your LLC exists with your state, and mismatched information can delay your application or create complications later.
What if I made a mistake on my EIN application?
Minor errors like address changes can be updated by filing Form 8822-B. Major errors like the wrong business name or responsible party require calling the IRS Business & Specialty Tax Line at 1-800-829-4933. It’s often easier to get it right the first time than to fix it later.
How long does an EIN last?
Forever, unless you formally dissolve your LLC. Once issued, your EIN stays with your business permanently. You don’t need to renew it or pay maintenance fees to the IRS.
Can I use my EIN immediately after getting the confirmation?
Yes, you can start using your EIN right away for banking, vendor applications, and other business purposes. You don’t need to wait for the official confirmation letter in the mail, though some institutions may prefer to see the official documentation.
Conclusion
Getting an EIN for your LLC is one of the easier parts of business formation — the hardest part is avoiding the paid services that charge for something the IRS provides free. Once you have your nine-digit number, you’re ready to open business bank accounts, establish vendor relationships, and handle your business taxes properly.
