Starting an LLC feels exciting until the paperwork starts asking for numbers you do not have yet. You form your company, get your Articles of Organization approved, and then suddenly the bank, payment processor, tax platform, payroll provider, or state agency asks for your EIN.
That is where many new business owners freeze.
An EIN sounds technical, but it is actually one of the simplest business IDs you can get. The IRS calls it an Employer Identification Number. It is a 9-digit federal tax ID used for tax filing and reporting purposes. Think of it as your LLC’s federal identity number, separate from your personal SSN or ITIN. The IRS uses Form SS-4 to issue EINs, and the IRS says you can get one directly from the agency for free.
For a small business owner, freelancer, Amazon seller, agency owner, consultant, or international founder, getting an EIN can change how seriously your business is treated. You can open a business bank account, apply for licenses, hire employees, set up payroll, file certain tax forms, and keep your personal identity more separate from your LLC.
The good news? If your LLC is already formed and you qualify for the online IRS application, you may get your EIN in minutes. The bad news? If you enter the wrong legal name, apply before your LLC exists, use a nominee, or choose the wrong LLC tax classification, you can create problems that take much longer to fix.
Let’s walk through it clearly.
Why Does an LLC Need an EIN?
An EIN is not just a random tax number. It connects your LLC to the IRS and, in many cases, to state tax systems, banks, payroll platforms, and compliance filings.
You usually need an EIN if your LLC:
- Has employees
- Has more than one member
- Elects corporate or S corporation tax treatment
- Needs to file employment, excise, partnership, or certain information returns
- Opens a business bank account
- Applies for business licenses
- Registers for state payroll or sales tax
- Is owned by a foreign person and has U.S. tax reporting obligations
The IRS states that businesses need an EIN for several tax-related reasons, including hiring employees, paying certain federal taxes, operating as a partnership or corporation, and changing business structure or ownership. It also says that businesses can request an EIN for banking or state tax purposes even when one is not required for federal tax purposes.
What Happens If You Skip It?
Skipping the EIN may not always create an immediate penalty, but it can slow down almost every serious business step.
Here is what can happen:
- Bank account delays: Many banks ask for an EIN before opening a business checking account.
- Tax confusion: Multi-member LLCs usually need an EIN because they are taxed as partnerships by default.
- Payroll problems: If you hire employees without an EIN, you cannot properly report federal employment taxes.
- Privacy issues: Without an EIN, you may keep using your SSN on W-9s, contractor forms, and business paperwork.
- State registration delays: Some states ask for a federal EIN before you complete sales tax, withholding, or employer registrations.
- Payment processor issues: Stripe, PayPal, Shopify Payments, Amazon, and other platforms may ask for your EIN to verify your business.
For international entrepreneurs, the EIN is even more important. It is often needed for U.S. banking, payment platforms, tax filings, and proof that your U.S. LLC exists as a business entity.
Before You Apply: What You Need Ready
Do not jump straight into the IRS form. Get your details ready first.
You should have:
- Approved LLC name exactly as shown on state records
- Formation state, such as Wyoming, Delaware, Florida, Texas, or New Mexico
- Formation date
- Business mailing address
- Responsible party name
- Responsible party SSN, ITIN, or valid foreign status entry
- Number of LLC members
- Reason for applying
- Principal business activity
- Expected employee information, if applicable
The IRS specifically says that if you are creating a legal entity, including an LLC, you should register it with the state before applying for an EIN. If you apply before forming the LLC, the EIN application may be delayed.
Here is the simple rule: form the LLC first, then get the EIN.
Step-by-Step Breakdown: How to Get an EIN for an LLC
This is the section you should keep open while applying. The EIN process is easy when the information is clean.
Step 1: Confirm That Your LLC Is Officially Formed
How to do it:
Check your state approval document. This may be called Articles of Organization, Certificate of Formation, Certificate of Organization, or Articles of Formation depending on the state.
Where to do it:
Go to your state’s Secretary of State website and search your LLC name in the business entity database.
Pro tip to save time:
Use the exact legal name shown in your state records. If your LLC is registered as “BrightStone Media LLC,” do not enter “Bright Stone Media” or “BrightStone Media, LLC.” Small name differences can trigger bank verification issues later.
Step 2: Choose the Right Application Method
You have four main ways to apply:
| Method | Best For | Timeline | Notes |
|---|---|---|---|
| Online IRS application | U.S.-based applicants with SSN or ITIN | Usually immediate | Fastest option |
| Fax Form SS-4 | U.S. or international applicants | About 4 business days if fax number is provided | Useful when online does not work |
| Mail Form SS-4 | Applicants who cannot use online or fax | Around 4 weeks | Slowest option |
| Phone | International applicants only | Often same call if accepted | Not available for domestic taxpayers |
The IRS online EIN tool is free and can issue an EIN immediately if approved. The online session must be completed in one sitting, and the application expires after 15 minutes of inactivity. The IRS also limits EIN issuance to one EIN per responsible party per day.
Where to do it:
Use the official IRS EIN application page, not a random paid website. The IRS warns that you never have to pay a fee to get an EIN.
Pro tip to save time:
Apply during IRS online tool hours and keep all LLC details beside you. Do not start the form while searching for your formation date or business address.
Step 3: Identify the Responsible Party Correctly
This is one of the most important parts of the EIN application.
The responsible party is the person who ultimately owns, controls, or manages the entity and its assets. The IRS says nominees are not authorized to apply for an EIN, and using a nominee can put the entity’s information and privacy at risk.
For most small LLCs:
- A single-member LLC owner is usually the responsible party.
- A multi-member LLC usually lists one managing member or person with real control.
- A manager-managed LLC may list the person who actually controls the company.
- A third-party service provider should not be listed as the responsible party just because they filed the form.
How to do it:
Enter the responsible party’s legal name and taxpayer ID details.
Where to do it:
On the IRS online EIN application or Line 7a and 7b of Form SS-4.
Pro tip to save time:
Do not use your registered agent as the responsible party unless that person truly owns or controls the business. A registered agent receives legal notices. That is not the same thing as controlling the LLC.
Step 4: Select the Correct LLC Type and Tax Classification
An LLC is a legal structure, not automatically a tax structure. That is where many people get confused.
For federal tax purposes:
- A single-member LLC is usually treated as a disregarded entity by default.
- A multi-member LLC is usually treated as a partnership by default.
- An LLC can elect to be taxed as a corporation or S corporation if eligible.
The IRS Form SS-4 instructions explain that a domestic LLC with two or more members is treated as a partnership by default, unless it elects corporate tax treatment. The instructions also give specific directions for disregarded entities, including single-member LLCs.
How to do it:
Choose the LLC option carefully and enter the number of members.
Where to do it:
In the IRS EIN Assistant or on Lines 8a to 9a of Form SS-4.
Pro tip to save time:
If you are a single-member LLC and just need an EIN for banking, state registration, or foreign-owned reporting, do not randomly choose “corporation.” That can create tax filing confusion.
Step 5: Choose the Reason for Applying
The IRS asks why you are applying for an EIN.
Common options include:
- Started a new business
- Hired employees
- Banking purpose
- Changed type of organization
- Purchased an existing business
For a new LLC, “Started a new business” is usually the cleanest choice. If you only need the EIN for a bank account and your LLC is otherwise not required to have one, “Banking purpose” may apply.
The Form SS-4 instructions say to choose only one reason and not enter “N/A” for this line.
How to do it:
Pick the reason that best matches your actual situation.
Where to do it:
In the IRS online application or Line 10 of Form SS-4.
Pro tip to save time:
Do not overthink this if your LLC is newly formed and you are starting business activity. Most new LLC owners will use “Started a new business.”
Step 6: Enter Business Activity and Employee Details
The IRS wants to know what your LLC does.
Examples:
- Digital marketing agency
- E-commerce retail
- Consulting services
- Software development
- Real estate investment
- Online education
- Content publishing
- Professional services
You may also need to answer whether you expect to hire employees within the next 12 months.
How to do it:
Use a simple, accurate business description. Avoid vague wording like “online business” if you can be more specific.
Where to do it:
IRS online application or Lines 13 to 17 of Form SS-4.
Pro tip to save time:
If you are not hiring employees yet, do not guess. Mark that you do not expect employees if that is true. You can handle payroll registrations later when you actually hire.
Step 7: Save the EIN Confirmation Letter Immediately
If your online EIN application is approved, the IRS will generate your EIN confirmation letter. This is commonly called CP 575.
How to do it:
Download, print, and save the confirmation letter as a PDF.
Where to do it:
At the end of the IRS online EIN application.
Pro tip to save time:
Do not close the page until you save the PDF. You may need the letter for banks, payment processors, tax professionals, affiliate networks, and vendor approvals. If you lose your EIN later, the IRS says you can request confirmation through an entity transcript or call the business and specialty tax line for Letter 147C.
How International Entrepreneurs Can Get an EIN for a U.S. LLC
If you are a non-U.S. resident forming a U.S. LLC, your process may be different.
You may not be able to use the online EIN application if your principal place of business is outside the U.S. The IRS says international applicants can apply by phone, fax, or mail. The phone number listed by the IRS for international EIN applicants is 267-941-1099, available Monday through Friday during IRS-stated hours.
If the responsible party does not have and is not eligible for an SSN or ITIN, the Form SS-4 instructions say to enter “foreign” or “N/A” on Line 7b.
Best Route for Non-U.S. Residents
| Situation | Recommended EIN Method |
|---|---|
| You have SSN or ITIN and U.S. principal office | Online may work |
| You have no SSN or ITIN | Fax, mail, or international phone |
| You need EIN quickly | International phone, if reachable |
| You want a paper trail | Fax Form SS-4 |
| You are unsure how to classify the LLC | Ask a CPA before filing |
Pro tip:
For foreign-owned single-member LLCs, be careful with Form 5472 and related reporting. A U.S. disregarded entity wholly owned by a foreign person may have additional information return obligations. The Form SS-4 instructions specifically reference foreign-owned U.S. disregarded entities filing Form 5472.
State-Specific Nuances: Wyoming, Delaware, and Florida
The EIN is federal, so the IRS process is the same across all states. Still, your state can affect what happens before and after you get the EIN.
Wyoming LLC
Wyoming is popular for privacy-focused and online businesses. You still need to form the LLC first through the Wyoming Secretary of State before applying for the EIN.
Wyoming LLCs have an annual license tax based on assets located and employed in Wyoming. The minimum is $60 or two-tenths of one mill on the dollar, whichever is greater. Wyoming also says an entity can be administratively dissolved if the annual report is not filed within 60 days after the due date.
EIN tip:
If your Wyoming LLC is owned by a non-U.S. resident, prepare Form SS-4 carefully. Your state formation may be fast, but your EIN can still take time if you cannot use the online IRS tool.
Delaware LLC
Delaware is common for startups, holding companies, and investors. After formation, you can apply for the EIN.
Delaware LLCs do not file an annual franchise tax report with the Division of Corporations, but they must pay a $300 annual tax by June 1. Failure to pay can trigger a $200 penalty plus monthly interest.
EIN tip:
Make sure your Delaware legal name matches the Certificate of Formation. Banks and payment processors often check the exact entity name.
Florida LLC
Florida is popular for local service businesses, e-commerce owners, consultants, real estate professionals, and creators.
Florida’s official LLC fee page lists a $125 total fee for a new Florida or foreign LLC, which includes the required filing fee and registered agent fee. It also lists the LLC annual report fee as $138.75, or $538.75 if received after May 1.
EIN tip:
After getting your EIN, Florida businesses may still need sales tax, reemployment tax, local business tax receipts, or industry-specific licenses depending on the business activity.
Cost and Timeline: What Will You Actually Spend?
Getting the EIN itself should cost $0 if you apply directly with the IRS. The IRS says the EIN tool is free, and it warns that you never have to pay a fee for an EIN.
Here is the realistic cost breakdown:
| Item | Cost | Required? | Notes |
|---|---|---|---|
| IRS EIN application | $0 | Yes, if EIN needed | Apply directly with IRS |
| LLC state formation fee | Varies by state | Yes before EIN | Must form LLC first |
| EIN service provider | $50 to $300+ | Optional | Convenience only |
| CPA/tax advisor help | $100 to $500+ | Optional | Useful for foreign-owned or tax election cases |
| Faxing Form SS-4 | Usually $0 to $20 | Optional | Depends on your provider |
| Mailing Form SS-4 | Postage cost | Optional | Slowest method |
| Registered agent | $0 to $300/year | Often needed | Required if you do not have an in-state agent |
| State annual report/tax | Varies | Yes in many states | Example: Delaware LLC tax is $300; Florida LLC annual report is $138.75; Wyoming minimum annual license tax is $60 |
Timeline by Method
| Method | Expected Timeline |
|---|---|
| Online IRS application | Usually immediate |
| Fax Form SS-4 | About 4 business days if fax number is provided |
| Mail Form SS-4 | Around 4 weeks |
| International phone | Often during the call if accepted |
The IRS says online EINs can be used immediately for most business needs, such as opening a bank account, applying for licenses, and filing paper tax returns. However, it may take up to 2 weeks before the EIN works for e-filing, TIN matching, or electronic federal tax deposits.
Common Mistakes to Avoid When Getting an EIN for an LLC
1. Applying Before the LLC Is Formed
This is one of the biggest mistakes. The IRS says to form the legal entity with the state before applying for the EIN.
2. Entering the Wrong Legal Name
Your EIN should match your LLC formation documents. Do not use your brand name unless it is the LLC’s legal name.
3. Listing a Nominee as the Responsible Party
A filing company, registered agent, or friend should not be listed unless they truly control the business. The IRS warns that nominees are not authorized to apply for an EIN.
4. Choosing the Wrong Tax Classification
Single-member LLC, multi-member LLC, partnership, corporation, and S corporation are not the same for tax purposes. If you choose the wrong option, talk to a tax professional before filing returns.
5. Applying Multiple Times
Do not apply online, then fax, then mail because you got impatient. The IRS instructions say to use only one method for each entity so you do not receive more than one EIN.
6. Losing the EIN Confirmation Letter
Save the confirmation letter immediately. Banks often ask for it.
7. Forgetting to Update Responsible Party Changes
If your responsible party changes, the IRS says changes must be reported within 60 days using Form 8822-B.
Comparison: EIN Application Options for LLC Owners
| Option | Pros | Cons | Best For |
|---|---|---|---|
| Apply online yourself | Free, fast, immediate letter | Only works for eligible applicants | U.S.-based LLC owners |
| Fax Form SS-4 | Works when online fails | Slower than online | International founders, complex cases |
| Mail Form SS-4 | Simple paper trail | Slow | Non-urgent cases |
| Hire a formation service | Convenient | Costs more for something IRS provides free | Busy owners |
| Use a CPA | Better for tax-sensitive cases | More expensive | Foreign-owned LLCs, S corp elections, multi-owner setups |
My practical advice: if your case is simple, apply yourself through the IRS. If your LLC has foreign owners, unusual ownership, tax election plans, or Form 5472 issues, pay for professional help before you submit anything.
2025-2026 LLC Compliance Checklist After Getting an EIN
Once your EIN is issued, do not stop there. Use it to set up the rest of your business foundation.
Federal Checklist
- Save the EIN confirmation letter.
- Create a business tax folder.
- File required federal returns on time.
- Register for EFTPS if you need to make federal tax deposits.
- Update the IRS if your responsible party or address changes.
- Check whether your LLC needs to file Form 1065, Schedule C, Form 1120, Form 1120-S, Form 5472, or employment tax returns.
Banking and Finance Checklist
- Open a dedicated business checking account.
- Keep personal and business money separate.
- Use the EIN for business payment platforms.
- Give vendors a completed W-9 when needed.
- Track business income and expenses from day one.
State Compliance Checklist
- File your state annual report.
- Pay franchise tax or annual license tax if required.
- Register for sales tax if you sell taxable goods or services.
- Register for payroll withholding if you hire employees.
- Keep your registered agent active.
- Maintain a current business address.
BOI Checklist for 2025-2026
As of FinCEN’s March 2025 interim final rule, entities created in the United States, including domestic LLCs, are exempt from BOI reporting requirements. FinCEN’s current definition of “reporting company” applies to certain foreign entities registered to do business in a U.S. state or tribal jurisdiction.
Still, do not ignore BOI completely. If your entity was formed outside the U.S. and registered to do business in a U.S. state, check the current FinCEN rules before assuming you are exempt.
FAQs About Getting an EIN for an LLC
1. Can I get an EIN before forming my LLC?
You should not. The IRS says to register your legal entity with the state before applying for an EIN because applying before formation may delay the application.
2. Is an EIN free for an LLC?
Yes. Getting an EIN directly from the IRS is free. Paid websites may charge for convenience, but the IRS itself does not charge an EIN fee.
3. Does a single-member LLC need an EIN?
Often, yes for practical reasons. Even when a single-member LLC may not need an EIN for every federal tax situation, banks, payment processors, state agencies, and privacy concerns often make getting one worth it.
4. Can a non-U.S. resident get an EIN without an SSN?
Yes. International applicants can apply by phone, fax, or mail. If the responsible party has no SSN or ITIN and is ineligible to obtain one, the IRS instructions allow “foreign” or “N/A” on Line 7b of Form SS-4.
5. How long does it take to get an EIN for an LLC?
Online applications can be approved immediately. Fax applications may take about 4 business days if you provide a fax number. Mail applications can take around 4 weeks.
6. Can I use my EIN right away?
Yes, for many business needs. The IRS says you can use the EIN immediately for opening a bank account, applying for licenses, and filing a tax return by mail. Some systems, such as e-filing and TIN matching, may take up to 2 weeks.
7. Do I need a new EIN if I change my LLC name?
Usually no. The IRS says you generally need a new EIN when ownership or structure changes, but not simply for a business name, address, or responsible party change.
8. What if I lost my EIN confirmation letter?
First, check your original IRS notice, business bank records, licenses, and past tax returns. If you still cannot find it, the IRS says authorized persons can call the business and specialty tax line to request the EIN.
9. Can I apply for more than one EIN in one day?
No. The IRS limits EIN applications to one EIN per responsible party per day, whether applying online, by phone, fax, or mail.
10. Should I pay an LLC formation company to get my EIN?
Only if you want convenience or your case is complex. For a basic U.S.-based LLC, you can usually apply directly through the IRS for free. For a foreign-owned LLC, multi-member setup, or tax election case, a CPA may be more useful than a generic filing service.
Final Action Plan
Here is the cleanest path:
- Form your LLC first with your state.
- Confirm the exact legal name from your approved formation document.
- Decide who the responsible party is based on real ownership or control.
- Choose the correct method: online for eligible U.S.-based applicants, phone/fax/mail for many international applicants.
- Complete the IRS EIN application carefully and use only one method.
- Download and save your EIN confirmation letter.
- Use the EIN to open your business bank account, set up tax records, register with state agencies, and keep your LLC compliant.
Getting an EIN is not the hardest part of running an LLC. But doing it correctly gives your business a cleaner foundation from day one.
